Description

The invention relates to the field of special agricultural and food technology, in particular to technologies and mobile installations, mainly for the disinfection of vans of vehicles used in the transportation of agricultural products.

Road transport has been widely used for transporting animals and agricultural products in the agricultural sector, which allows us to simplify and speed up transportation to processing enterprises and sales. When operating the equipment, it is necessary to comply with sanitary requirements, namely, to carry out regular cleaning and disinfection of vans of vehicles.

During transportation in a car van, favorable conditions arise for the development of pathogenic microflora, such as: high humidity, temperature, the presence of a nutrient medium and when dangerous and harmful microorganisms get on work surfaces, such as walls and floors, their development and growth begins. All this can lead to infection of the finished product and reduce its safety and quality.

A known method of disinfection based on water-dispersible paint with a cationic active substance, which increases the period of residual biocidal (bactericidal and fungicidal) activity (RF patent No. 226951, IPC A61K 33/10, A61K 33/14, published on 02.27.2005. )

Surfactants can have a negative impact on the environment (water quality, self-cleaning ability of water bodies, living organisms, including humans, animals, birds).

A known method of photocatalytic disinfection of surfaces, including transport, comprising spraying an ultrasonically treated aqueous suspension of titanium dioxide nanoparticles with an average diameter of 23.3 nm at a concentration of 0.5 g / l and subsequent irradiation of the surface with narrow-band bactericidal ultraviolet radiation (RF patent No. 2404814, A01L 2/10, publ. 11/27/2010).

The method is complex and time-consuming, provides for three types of equipment for implementation, which lengthens the time and cost of processing.

A known method of disinfection of vehicles and containers after transporting livestock cargo, including their processing with a disinfectant containing a solution of oxidants, propylene glycol, sodium nitrite, sodium benzoate, the products of the interaction of glycerol with formic acid, and processing is carried out once at a disinfectant consumption of 0.15-0 , 25 l / m with an exposure of 55-65 minutes, immediately after treatment with a disinfectant, the surface of vehicles and containers is additionally irradiated for 30-60 m n constant ultraviolet light at a wavelength of 254 ± 5 nm at a dose of 12,8-25,6 J / cm ² (RF Patent №2489170 IPC A61L 2/16, publ. 10.08.2013 g).

The method is complex, time-consuming due to the multicomponent disinfectant and the need for an ultraviolet device.

A known method of disinfection of vehicles and containers after transportation of livestock cargo, including their processing with a disinfectant containing active chlorine, the treatment being carried out twice at 15-25 ° C at a rate of 0.5-1.0 l / m ² with an interval of 90-95 minutes (RF patent No. 2403916, IPC A61L 2/16, publ. November 20, 2010).

Chlorine and its preparations are toxic compounds, so working with them requires strict adherence to safety precautions. The inability to use it in large quantities is associated with the formation of halogen-containing compounds (HSS) with pronounced general toxic properties and long-term effects (embryotoxic, mutagenic, carcinogenic).

A known method of disinfection of vehicles and containers after transportation of livestock cargo, including their processing with a disinfectant containing a solution of oxidizing agents, propylene glycol, sodium nitrite, sodium benzoate, the products of the interaction of glycerol with formic acid, and processing is carried out once at a consumption of disinfectant 0.25-0 , 35 l / m ² with an exposure of 55-65 minutes (RF patent No. 2403916, IPC A61L 2/18, publ. 08.20.2012).

Sodium nitrate has a generally toxic and toxic property, as well as a carcinogenic effect, which is unsafe for people who carry out disinfection.

A known method of disinfection with water vapor mixed with peracetic acid as a disinfectant material through a steam generator (RF application No. 2012106318, IPC A01M 7/00, publ. 08/28/2013).

However, a sufficiently strong smell of vinegar, inherent in deoxones, complicates their widespread use.

A known method of disinfection with steam mixed with peracetic acid as a disinfecting material by means of a steam generator with an ejector (French patent No. 2954705, IPC A61L 2/22, publ. 08.28.2013).

However, the complex hardware implementation and the rather strong smell of vinegar inherent to deoxones make their widespread use difficult. To implement the method there is no portable, mobile equipment with the possibility of disinfection by one operator. The method cannot be attributed to environmentally friendly technologies for living organisms.

A known method of high-speed disinfection of surfaces coming from the nozzle of a steam generator with dry steam with 35% hydrogen peroxide as a disinfecting material at a relatively high temperature, and the remaining hydrogen peroxide vapor is then removed from the tank by purging it with hot air with high temperature (RF patent No. 2275208, IPC A61L 2/00, A61L 2/016, publ. 04/27/2006).

The method allows you to quickly and economically disinfect various containers with a small surface treatment. Hydrogen peroxide is odorless and quickly decomposes in the environment into non-toxic products. However, hydrogen peroxide is inconvenient for use, has a local irritant effect and has a low bactericidal activity, so it is not used for disinfection of large areas.

Closest to the proposed method is a method of disinfecting surfaces of premises and plants with water vapor mixed with alcohol as a disinfecting material using a telescopic rod with a perforated nozzle (RF application No. 2012106318, IPC A01M 7/00, published on 08/28/2013 - prototype).

The method is simple, but has a low bactericidal activity at low concentrations of alcohol. At higher concentrations, odor deodorization is required, which is not economically feasible. The use of flammable material (alcohol) requires compliance with fire safety.

A known machine for the complex disinfection of agricultural production facilities of poultry complexes, containing installed on a self-propelled chassis with an engine, water tanks, a foaming agent and a disinfectant solution with a heating system, connected to a pump, a compressor, a mixer, a piping system and a flexible outlet hose with nozzles, and the mixer the inlet is connected to the pump and through the pressure reducer and the receiver to a compressor, and at the outlet to a flexible hose (RF patent No. 2099088, A61L 2/00, publ. 12/20/1997).

The large dimensions and weight of the machine limit its use in the disinfection of vans for transportation of agricultural products.

A mobile cleaning device is known, including a water tank, a pump, a heater and a water vapor output device with a temperature of 170-185 ° C (patent EP 1862229, B08B 3/02, publ. 05.12.2007).

The device provides one type of disinfecting effect - water vapor at high temperature and pressure, which requires special safety measures. This type of processing requires a significant processing time to ensure the heating of the treated surfaces. The disinfection effect will be instantaneous and does not have a prolonged effect.

A device for disinfection of water vapor containing a steam generator and a nozzle connected to a steam generator (patent WO 9948538, A61L 2/07, publ. 09/30/1999).

The device provides one type of disinfecting effect - water vapor, which does not suppress the entire pathogenic flora formed in vans of vehicles used in the transportation of agricultural products.

A known disinfection machine containing a steam generator, sources of hydrogen peroxide, a source of disinfectant in the form of peracetic acid, a means for mixing water vapor and peracetic acid and an ejector mixture (patent WO 2011076947, A61L 2/22, A61L 9/03, A61L 9/14 , published on June 30, 2011).

The machine is suitable for disinfection of only small work surfaces, including any standard container for food packaging, and the processing of work surfaces in contact with agricultural or food products requires special safety measures and is laborious.

A known installation for applying coatings using water vapor, containing a steam generator with a nozzle connected to a source of coating material in liquid form (patent US 59890705, B05B 7/00, B05B 7/04, B05B 7/06, publ. 09/22/2005, )

Disinfecting plants using varnishes in bactericidal compositions are not environmentally friendly and fireproof. The disinfection operator must be equipped with personal protective equipment against disinfectant material on the surface of the skin and respiratory tract. The introduction of the liquid coating material in the form of varnish directly into the nozzle disrupts the steam jet, preventing a good mixing of steam with the coating material, which reduces the quality of the coating.

Closest to the proposed invention is a device for disinfection and sanitization of objects using water vapor, containing a container for accommodating the disinfectant liquid added to the steam during its supply, a tubular body forming a chamber for discharging steam from a source of compressed steam, having a handle for transferring and a nozzle integrated inside the chamber at its closed end, the chamber being open at the other end to supply steam to the disinfection object and has a cross-sectional area greater than the cross-section the nozzle opening is 30-150 times, and the container for placing the disinfectant liquid is fixed outside the tubular body with the possibility of supplying the specified liquid to the chamber cavity for mixing it with steam before disinfection of the object (RF patent No. 2409390, B05B 7/00, B05B 7/04 , B05B 7/06, B05B 7/16, B05D 1/02, publ. 09/22/2005 - prototype).

The device allows you to disinfect small objects with a small work surface, including surgical and / or medical instruments and equipment. To process objects with a larger surface, for example, motor transport salons for transporting agricultural products or premises for its storage and processing, a large disinfectant tank is required, which increases the weight and dimensions of the device and complicates the manual transfer of the device during disinfection. It may be necessary to frequently refill the container with the indicated liquid, which lengthens and complicates the disinfection process. In addition, the liquid is fed into the chamber from below and it enters directly into the steam without preheating, which reduces the temperature of the steam and requires high precision dosing of the liquid into the chamber to ensure uniform distribution of the disinfectant material in the steam without spray. Equipping the device with an additional device to prevent liquid splashing outside the chamber significantly complicates and increases the cost of the device. At the same time, more time is required for maintenance, since it is difficult to clean and repair the device.

The technical result of the invention of the method is to create a universal accessible disinfection technology without the use of harmful, toxic, flammable materials, providing high antimicrobial activity in a wide range of antibacterial, antifungal effects for effective environmentally friendly disinfection of air and work surfaces using simple portable equipment for the production of humate aerosol in water vapor by one operator.

The technical result of the invention of the installation is to create a high-speed universal environmentally friendly and fireproof, portable portable installation for high-quality integrated disinfection of large surfaces and hard-to-reach surfaces in industrial and field conditions with at least one operator with minimal disinfection and maintenance costs.

The technical result of the invention of the method is achieved by the fact that in the method of treating work surfaces with a disinfectant solution using water vapor, including the formation of a mixture of a disinfectant solution and water vapor during the processing of the work surface, humate is used as a disinfecting solution, and this mixture is a humate aerosol in water couple.

It is advisable to have a humate aerosol in water vapor with a temperature of at least 60 ° C and a dispersion of 5-10 microns.

Preferably, the concentration of humates in water vapor is in the range of 80 to 150 ml / l. As a disinfecting solution, humate with a content of humic acids of at least 19.0 g / l and a total of humic and fulvic acids of at least 28.0 g / l, including the feed liquid additive “Kormogumat AS”, was used.

Preferably, the release of humate aerosol in water vapor to the working surface for processing is carried out at a distance of not more than 0.5 meters from the specified surface. It is advisable to treat the working surface with a humate aerosol in water vapor once for 15-20 seconds.

The technical result of the invention is achieved in that the installation for treating work surfaces with a disinfectant solution using water vapor, comprising a steam generator with a steam line and a nozzle integrated in a tubular body having an open end for disinfecting solution discharge with steam, and a container for the disinfecting solution is provided an autonomous source of disinfectant solution in the form of a humate, a container for a disinfectant solution is formed inside the tubular body and is made in the form of a chamber with an external odnym pipe for connection to an autonomous source of disinfecting solution, said chamber being arranged to heat the nozzle and introducing the disinfectant solution into the nozzle channel.

The nozzle of the steam generator is made in the form of a spacer sleeve, the cavity of which is the channel of the nozzle, and the specified sleeve is tightly installed in the tubular chamber and is made with elongated inlet and outlet conical parts mated with smaller bases so that a ring-shaped chamber is formed in the tubular body, inner wall which is the nozzle wall.

The spacer sleeve inside the elongated inlet conical part has a plurality of helically arranged disinfectant solution input elements from the tubular body chamber to the nozzle channel.

It is advisable that each element of the input of the disinfectant solution from the chamber of the tubular body into the nozzle channel be made in the form of a tube with a bevel at the end facing the open end of the tubular body.

In the chamber of the tubular body, the inlet pipe is preferably made over the inlet conical elongated part of the spacer sleeve.

It is advisable to make the spacer sleeve removable, the tubular body to perform with an annular groove for installation in it of the specified sleeve with the possibility of fastening by a fixing element.

A humate with a content of humic acids of at least 19.0 g / l and a total of humic and fulvic acids of at least 28.0 g / l, including the feed liquid additive Kormogumat AS, was used in an autonomous source of disinfecting solution.

Preferably, the tubular body chamber can be connected to an autonomous source of disinfectant solution through a dispenser integrated in the connecting hose for connection to the inlet pipe. The dispenser is preferably made in the form of a pump.

It is advisable to make the tubular body in the form of a nozzle on the steam line of the steam generator. Preferably, the steam generator and the stand-alone source of the disinfectant solution are portable.

When conducting patent research, no solutions were found that are identical to the claimed, and therefore, the proposed solution meets the criterion of "novelty." The invention does not follow explicitly from the known solutions, therefore, the proposed invention meets the criterion of "inventive step".

A method of treating work surfaces with a disinfectant solution using water vapor comprises forming a mixture of a humate disinfectant solution and water vapor during processing of a work surface with a humate concentration in the water vapor of from 80 to 150 ml / l. The specified mixture is a humate aerosol in water vapor with a temperature of at least 60 ° C, a dispersion of 5-10 microns and a pH of 7 to 9. Processing of the working surface is carried out once for 15-20 seconds by releasing a humate aerosol in water vapor at a distance of not more than 0.5 meters from the indicated surface. A humate with a content of humic acids of at least 19.0 g / l and a total of humic and fulvic acids of at least 28.0 g / l, for example a feed liquid additive with a high concentration of humic substances "Kormogumat AS" (TU 9296-001, was used as a disinfecting solution) -44909314-2007, manufacturer of LIKO LLC, Ryazan).

The method can be implemented using a portable installation for processing work surfaces with a disinfectant solution using water vapor in figure 1. The installation comprises a steam generator 1 with a steam line 2 and a nozzle 3 integrated in the tubular body 4 (Fig. 2), having a chamber 5 for the disinfecting solution inside and an open end 6 for discharging the disinfecting solution with water vapor. In the tubular body 4, the chamber 5 has an external inlet pipe 7 in the form of a fitting, and the chamber 5 is made with the possibility of heat exchange with the nozzle 3 and the introduction of a disinfecting solution into the channel 8 of the nozzle 3. The nozzle 3 is made in the form of a spacer sleeve, the cavity of which is the channel 8 of the nozzle 3 The spacer sleeve is made with input elongated and output conical parts 9, 10 mated with smaller bases in such a way that a ring-shaped chamber 5 is formed inside the tubular body 4. The nozzle 3 inside the elongated inlet conical part 9 has a plurality of helically arranged disinfectant solution input elements from the chamber 5 of the tubular body 4 into the channel 8 of the nozzle 3.

Each input element of the disinfectant solution from the chamber 5 of the tubular body 4 to the channel 8 of the nozzle 3 is made in the form of a tube 11 with a bevel 12 at the end facing the open end 6 of the tubular body 4. The inlet pipe 7 (fitting) of the chamber 5 of the tubular body 4 is made over the inlet tapered elongated portion 9 of the spacer sleeve. The nozzle 3 is removable for periodic cleaning. In this case, the tubular body 4 is made with an annular groove for installation of a nozzle 3 in it with the possibility of fastening by a fixing element 13 (for example, a nut). The installation is equipped with an autonomous source 14 of disinfectant solution with a capacity of 5 to 10 liters, which provides the possibility of continuous or periodic refueling of the chamber 5 of the tubular body 4 with a disinfectant solution. An autonomous source of disinfectant solution is a liquid humate (potassium or sodium), which is an environmentally friendly means for suppressing a wide spectrum of pathogenic flora, including E. coli, staphylococci, viruses, bacteria.

The chamber 5 of the tubular body 4 is configured to be connected to an autonomous source 14 of disinfectant solution through a dispenser 15 integrated in the connecting hose 16. The dispenser 15 is preferably made in the form of a pump. The tubular body 4 can be made in the form of a threaded nozzle on the steam line 2 of the steam generator 1 (not shown in Fig.).

A steam generator 1 and an autonomous source of disinfectant solution 14 are made with the possibility of transferring by one operator.

Installation for processing work surfaces with a disinfectant solution using water vapor works as follows. The water entering the steam generator 1 is heated to a boiling point, as a result of which steam is formed. At the same time, the disinfectant solution is supplied from an autonomous source 14 through a connecting hose 16 through a dispenser 15 (in the form of a pump) to an annular chamber 5 formed inside the tubular body 4. The input elements of the disinfectant solution in the form of tubes 11 provide its drip supply to the channel 8 of the nozzle 3 through spirals.

Superheated water vapor through the steam line 2 enters the channel 8 of the nozzle 3, in which the disinfecting solution is dispersed. The resulting mixture of aerosols of the disinfecting solution and water vapor is evenly distributed in the nozzle 3 using these tubes 11 made with bevels 12.

The wall of the nozzle 3 is at the same time the inner wall of the chamber 5, which provides good heat transfer for heating the disinfectant solution contained therein. Due to the fact that the tubes 11 with bevels 12 are installed in the channel 8 of the nozzle 3, they are heated with water vapor and the disinfectant solution evaporates towards the open end 6 of the tubular body 4 for application to the surface to be treated.

Thus, at the exit of the tubular chamber 4, a cloud is formed consisting of a mixture of water vapor and an aerosol of a disinfectant solution, which makes it possible to obtain droplets of smaller diameter and distribute them evenly on the working surface. Due to the temperature difference between the steam and the working surfaces, for example, the wagon interior, a phase transition and condensation of the disinfectant solution occur, which helps to improve the adhesion of the solution to the working surface. Due to the adhesion of the solution to the surface, a layer of disinfectant is created, which in turn will prevent the propagation of pathogenic microorganisms. The combined action of superheated steam and a disinfecting aerosol allows for the disinfection of the working surfaces of an automobile van with prolonged action. The implementation of the removable nozzle provides the convenience of cleaning it from precipitation of the disinfectant solution.

In the installation, the steam generator and an autonomous source of disinfectant solution have the optimal weight and dimensions, which ensures high-speed processing of large surfaces. The installation also provides a steam disinfection mode when the connecting hose 16 is removed from the inlet pipe 7 of the chamber 5. In the absence of disinfectant liquid in the chamber 5, the installation operates in the indicated mode. In this case, the inlet pipe 7 is closed by a plug (not shown in Fig.). It is advisable to apply this mode before disinfection for preliminary cleaning of work surfaces, including dust, dirt, mold.

The proposed method and installation have been tested. During the experiment, a method for treating the body surfaces of a vehicle carrying farm animals was evaluated. The treatment was carried out with a disinfectant - humate in the form of a liquid feed additive "Kormogumat AS" using water vapor. As a disinfectant, a humate solution with a pH of 7 and a pH of 9 was used. The humate concentration in water vapor was 80 ml / L and 150 ml / L, respectively. The temperature of the humate aerosol in water vapor 60 ° C with a dispersion of 5-10 microns. The working surface was treated with humate aerosol in water vapor once at a distance of 50 cm for 15-20 seconds.

The treatment result was evaluated by such microbiological indicators as KMAFAnM, BGKP, the presence of enterococci, molds and pathogenic microflora, including St. aureus. Washings were taken from 100 cm of various sections of the treated surface with sterile moistened cotton-gauze swabs fixed on a wire in a tube stopper containing 5 cm ^{3 of} sterile physiological sodium chloride solution. Washings were taken 15 and 30 minutes after treatment, thereby assessing the time of action of aerosol humate in water vapor on microbial cells (exposure). The processing results are presented in table 1.

The experimentally obtained data allow us to conclude that the humate aerosol in water vapor has a universal wide spectrum of microflora suppression, including pathogenic on working surfaces, reducing its activity by 80-100% at low humate concentrations in water vapor, and may be widely used in agriculture. The method and installation is advisable to use for prompt and economical disinfection of surfaces of various types, of any shape and area, sensitive to microbiological damage or contamination. In this case, the use of harmful, toxic, flammable materials is excluded, which contributes to the preservation of environmental cleanliness.

Installation is simple and safe design and operation. Ease of use will allow the installation to be widely used in agriculture, mainly for the treatment of salons in vans of vehicles for transporting agricultural products, as well as additionally for the disinfection of premises, containers and utensils for animal husbandry, storage and processing of agricultural products.
