Description

The invention relates to means of disinfection using ultraviolet radiation, namely to bactericidal irradiators of open type, and is aimed at increasing the efficiency of bactericidal disinfection of air and surfaces in various, mainly medical premises in the absence of people.

The prior art bactericidal irradiator of open type, containing a housing equipped with cartridges, in which bactericidal mercury lamps are fixed, connected to the ballast of the power supply and control unit (RU124152 U1, A61L 2/10, 2012). However, the design of the housing of this irradiator, as well as other known devices of this type, as a rule, does not provide the possibility of placing three or more bactericidal mercury lamps, which reduces the efficiency of disinfecting air and contaminated surfaces in large rooms.

The technical result, to which the invention is directed, is to increase the efficiency of bactericidal disinfection of air and various surfaces in large rooms.

The solution of the task and the achievement of the claimed technical result is ensured by the fact that in a bactericidal irradiator containing a body equipped with cartridges in which bactericidal mercury lamps are fixed, connected to the ballasts of the power supply and control unit, according to the invention, the body is made in the form of a hollow tubular profile with an internal a through channel, on the side surface of which cartridges are installed outside, in which bactericidal mercury lamps are fixed, while a fan is placed in the through channel of the tubular profile, and the case is mounted vertically on supports.

Alternatively, the fan may be mounted at the top of the tubular polyhedral duct.

Alternatively, the fan may be a fan installed at the bottom of the tubular polyhedral duct.

Alternatively, the fan may be a fan installed in the middle part of the tubular polyhedral duct.

In addition, the body is placed on supports equipped with wheels with brakes.

In addition, the power supply and control unit is equipped with a lamp operating time meter.

In addition, the power supply and control unit is equipped with a turn-on delay unit.

In the claimed bactericidal irradiator, linear direct low-pressure mercury gas discharge lamps or low-pressure gas-discharge mercury lamps with one-sided U-shaped or H-shaped leads can be installed.

The claimed embodiment of the body in the form of a hollow tubular profile with an internal through channel, on the side surface of which cartridges are installed outside, in which bactericidal mercury lamps are fixed, significantly increases the number of bactericidal lamps placed on the body, and, accordingly, increases the flow of bactericidal radiation, which increases efficiency bactericidal disinfection of air and various surfaces and allows you to intensively and evenly process rooms of large volume and in less time.

In addition, due to the circulation of air flows caused by the lifting movement of air in the through channel of the hollow tubular body, created by the fan, intensive movement and uniform distribution of the disinfected air throughout the volume of the treated room is ensured, which increases the efficiency of bactericidal disinfection, especially of large rooms. In this case, the walls of the housing and, accordingly, the bactericidal mercury lamps are cooled, which increases the share (power) of useful ultraviolet bactericidal radiation and increases the period of effective operation of the bactericidal mercury lamps, and further increases the efficiency of the bactericidal irradiator.

In addition, the presence in the power supply and control unit of an electronic digital hour meter (operating time meter) of the lamps provides the possibility of timely replacement of a bactericidal mercury lamp that has exhausted its resource, in which the radiated ultraviolet flux decreases by more than 30%, further increases the reliability and efficiency of the bactericidal irradiator.

In addition, the presence in the power supply and control unit of the turn-on delay unit and the operating time setting unit ensures the reliability of automatic control of the operation of the declared open bactericidal irradiator without the operator being in the treated room.

On FIG. 1 shows a general view of a bactericidal irradiator,

in FIG. 2 is a section A-A in FIG. one,

in FIG. 3 - section B-B in Fig. one.

The bactericidal irradiator contains a vertically mounted body 1, made in the form of a hollow tubular profile with an internal through channel 2 (cylindrical or polyhedral pipe), on the side surface - the wall of which cartridges 3 are installed outside, in which linear low-pressure gas-discharge mercury lamps 4 or gas-discharge lamps are fixed. low-pressure mercury lamps with one-sided U-shaped or H-shaped terminals (not shown in the drawing) connected to electronic ballasts (not shown in the drawing) of the power and control unit 5, while an axial fan 6 is installed in the through channel 2, preferably in its upper part. Alternatively, the fan 6 can be installed at the bottom of the channel 2 or in the middle of the channel 2 (not shown).

The body 1 is mounted vertically on supports 7, equipped with wheels 8 with brakes 9, which makes it possible to easily move the bactericidal irradiator and securely fix it in place.

In addition, the power supply and control unit 5 is equipped with an electronic digital lamp operating time meter (not shown in the drawing), and can also be equipped with a turn-on delay unit and an operating time setting unit (not shown in the drawing).

An open type bactericidal irradiator is designed to disinfect air and various surfaces in rooms in the absence of people and works as follows.

The bactericidal irradiator is installed in a decontaminated room and the power and control unit 5 is connected to the power supply (mains). In addition, (as an option) after a time interval set by the turn-on delay unit, for example, 30 ÷ 60 seconds, during which the operator leaves the premises, voltage is automatically applied to the electronic ballasts by means of the power supply and control unit, which starts and maintains the operating mode bactericidal low-pressure mercury gas lamps 5, and the fan 6 turns on. The low-pressure bactericidal mercury lamps 5 generate ultraviolet rays with a wavelength of 253.7 nm into the environment, which have the greatest bactericidal effect, aimed at destroying bacteria, viruses, spores, fungi, yeast, etc., which ensures effective disinfection of air and various surfaces in the treated room. At the same time, as a result of the lifting movement of air in the through channel 2 of the tubular body 1, driven by the fan 6, there is an intensive circulation of air flows, which ensures efficient movement and uniform distribution of the disinfected air throughout the volume of the treated room, which increases the efficiency of bactericidal disinfection, especially of large rooms. , as well as the process of cooling the walls of the housing 1 and, accordingly, bactericidal mercury lamps 5, which increases the share (power) of useful ultraviolet bactericidal radiation and increases the period of effective operation of bactericidal mercury lamps.

After working off a certain time set by the block-setter of the operating time, the power supply of the bactericidal irradiator is automatically turned off. The presence of an electronic digital lamp operating time meter makes it possible to timely replace the spent bactericidal mercury lamp 5, which increases the reliability of the irradiator and, accordingly, increases the efficiency of the disinfection process.
