[Prior Art] Normally, used medical waste, used disposable diapers, etc. at public facilities, hospitals, private practices, etc. are not disposed of on their own premises, but are treated as medical waste at specialized waste disposal sites. In many cases, this is outsourced to a contractor;
This is because conventionally, processing such medical waste on one's own premises required a large amount of space, a great deal of effort, and a large investment of capital. In addition, when outsourcing to such specialized disposal companies, it goes without saying that the people involved in transporting these medical wastes are constantly exposed to the risk of secondary infection, and the quality of the disposal company is also affected. In some cases, there are even concerns about illegal dumping.

[0003]Furthermore, in the conventional incinerator, the combustion chamber has a one-chamber structure, and medical waste, disposable diaper general garbage, etc. are incinerated all at once in one combustion chamber. In particular, when medical waste with the risk of secondary infection is incinerated together with other general waste, there are deep concerns as to whether the process will be sterilized safely and completely. It existed.

0004

[Problems to be Solved by the Invention] Therefore, the present invention aims to solve the problem of incinerating infectious medical waste and general garbage together, since conventional incinerators have a one-room incinerator. The technical challenge is to avoid incomplete combustion, especially situations where infectious medical waste is not sterilized, leading to serious consequences.

Another technical object of the present invention is to provide a medical incinerator that is compact in size, economical in price, and easy to operate, and is capable of discharging medical waste from hospitals, medical laboratories, medical facilities, private practices, etc. This means safely incinerating garbage, including waste, on one's own premises.

[0006]Furthermore, another technical object of the present invention is to provide a medical incinerator for minimizing the risk of secondary human infection during the transportation and handling of medical waste. be.

Still another technical object of the present invention is to provide a medical incinerator that can accurately and quickly process medical waste and disposable diapers without storing them for a long period of time.

[0008]

[Means for Solving the Problems] The means adopted by the present inventor to solve the above problems are as follows.

In other words, the two chambers, the general combustion chamber (9) and the sterilization combustion chamber (8), are of separate and independent structure, and the cyclone chamber (11) is further added to form a three-chamber structure. Medical waste is incinerated in the combustion chamber (9), and medical waste is incinerated in a separate sterilization combustion chamber (8) to confirm sterilization, and high-temperature gas generated during incineration in the sterilization combustion chamber (8) is is sent to the general combustion chamber (9) as auxiliary fuel to assist the incineration process in the general combustion chamber (9), thereby avoiding wasted energy and sterilizing the combustion chamber (8).
and sends odor, smoke, soot, etc. generated during and after incineration in the general combustion chamber (8) to the cyclone chamber (11),
It is an object of the present invention to provide a medical incinerator equipped with a means for deodorizing, reburning, and separating operations, and making it possible to discharge the air without polluting the surrounding atmosphere.

[Example] Referring to FIG. 1, reference numeral (1) is a main body of a medical incinerator according to the present invention, and a sterile combustion chamber (8) is provided inside.
, a general combustion chamber (9), and a cyclone chamber (11) are formed separately and independently, and outside there is a chimney (2) that discharges exhaust gas as clean air, and a chimney (2) that promotes smooth combustion of waste. , a turbo blower for complete combustion (3), a door used when putting medical waste etc. into the sterilized combustion chamber (4), a burner for general combustion chambers (5), and a disposable one for general combustion chambers. It consists of a sliding door (6) for putting in diapers and the like, and an ash outlet (7) below the sliding door for scraping out the ash that has become the remains of the incineration. In the sterile combustion chamber, in order to incinerate medical waste,
In order to prevent the scattering of infectious bacteria, viruses, etc. during combustion, this sterilization room door (4) guarantees complete sealing.

[0011] According to Figure 2, the blacked-out arrow (X)
indicates the flow of thermal heat released from the burners (5, 12, and 13), the white arrow (Y) indicates the intake of air necessary for combustion and clean exhaust, and the dotted arrow (Z)
shows the flow of hot gas after combustion. This hot gas passes from the sterilized combustion chamber (8) through the hot gas vent (10) and into the general combustion chamber (9) via the upper and lower parts of the rostre (14) provided in the general combustion chamber (9). The cyclone room (11) helps incinerate the disposable diapers etc. sent and thrown in.
will be sent to. Incineration in the general combustion chamber (9) is carried out by a dedicated burner (5), but in the sterile combustion chamber (8)
With the help of the hot gas delivered from the engine, less firepower is used, resulting in savings in the amount of energy used.

Referring to FIGS. 3 and 4, the sterile combustion chamber (8
) adopts a bed-type combustion method, incinerating medical waste such as syringes and needles containing infectious harmful substances at high temperatures of 500°C to 700°C; Turn infectious bacteria and viruses into harmless waste. After the incineration is finished, the door (4) is opened to take out the incinerated ash waste, etc., and dispose of it. On the other hand, the general combustion chamber (9) uses a grate combustion method, and general garbage such as used disposable diapers is incinerated at a high temperature of 700°C to 800°C, and the embers of the incinerated disposable diapers are turned into ash. The ash passes through the rostre (14) and falls into the ash basin, where it is taken out from the ash outlet (7) and disposed of. The combustion exhaust gas from the sterilized combustion chamber (8) and the general combustion chamber (9) is sent to the cyclone chamber (11) together with generated odors, smoke, soot, etc. The cyclone chamber (11) consists of a burner heating section and a cyclone section, and the smoke and odor sent from the general combustion chamber (9) are heated to 700°C to 800°C by the burner (13) installed in the same room. The black smoke is re-burned and the black smoke becomes colorless, and it is thermally decomposed to deodorize the odor, and the soot and dust are separated and captured by the equipped cyclone dust collector (15), and then cleaned through the chimney (2). It is released into the atmosphere in a safe condition.

The turbo blower (3) has air inlets (17, 17b,
17c and 17d) into the sterile combustion chamber (8) and the general combustion chamber (9) to promote the combustion of waste in the sterile combustion chamber (8) and the general combustion chamber (9). and completely burn it out.

Reference numeral (18) indicates a hot gas reservoir formed at the bottom of the sterilizing combustion chamber (8).
When a large amount of hot gas is released from the combustion chamber (10), it acts as a cushion tank for the hot gas to flow smoothly through the passage (10), and also serves as a cushion tank for the hot gas to flow smoothly through the passage (10).
It also has the effect of heating the floor surface of (8) from below, assisting combustion in the sterilization combustion chamber (8), and helping to save fuel consumption.

[0015] The inventor calculated the numerical value of the composition of garbage through statistical research and data collection as a guideline when using this medical incinerator, and created a table as shown in Table 1 below.

[0016]

[Table 1]

[0017] When the combustible components were analyzed, their compositions were as shown in Table 2 below.

[0018]

[Table 2]

When the infectious medical waste shown in the above data and general garbage such as used disposable diapers were incinerated using the medical incinerator of the present invention, it was found that the incinerator had a sufficiently satisfactory incineration capacity.

Normally, the capacity of the medical incinerator according to the present invention is 15 kgs of infectious medical waste in the sterile combustion chamber (8) per hour, and 15 kgs of used diapers, etc. in the general combustion chamber (9). It was 60Kgs per hour.

The preferred embodiments of the present invention have been described above, but, like conventional incinerators, only general garbage such as paper diapers or only medical waste can be stored in the respective general combustion chambers (9) or It is also possible to incinerate it in a sterile combustion chamber (8). In this way, if the incineration is carried out separately, energy will be wasted, and it goes without saying that it is desirable to operate these two chambers at the same time as the gist of the present invention.

[0022]

[Effects of the present invention] According to the present invention, infectious medical waste can be easily disposed of on one's own premises, thereby preventing secondary infection through transportation, and is useful for many medical institutions, especially hospitals. There is no doubt that this will be great news.

Furthermore, the medical incinerator according to the present invention has an extremely compact design and can be provided at a reasonable price, so that it can be used in public facilities such as hospitals as general garbage within their own premises. At the same time as incinerating used disposable diapers, it is now possible to safely dispose of infectious medical waste such as syringes, needles, blood collection tubes, etc., and its value in terms of social hygiene and national health is extremely high. It is something that will be done.
