Description

Highly infectious medical waste incinerator

technical field

The utility model relates to a medical waste incinerator with an improved structure, in particular to an incinerator applied to highly infectious medical waste. It has the effect of complete combustion, which can avoid the leakage and pollution of highly infectious medical waste.

Background technique

Most of the incinerators in the prior art have a main combustion chamber and a secondary combustion chamber. The main combustion chamber burns waste, and the waste gas produced is guided to the secondary combustion chamber for secondary combustion and then discharged. Since the secondary combustion chamber in the prior art is mostly equipped with a heater in a single large space, the heater heats and burns the inflowing exhaust gas, so it is impossible to completely burn the introduced exhaust gas, especially when a large amount of exhaust gas is quickly introduced into the main combustion chamber It is more obvious that this will have a very bad impact on the discharge of exhaust gas in the following procedures, and the secondary pollution of the environment is even more serious. If waste with toxins is processed, the exhaust gas containing toxic substances will be discharged without complete combustion, and the impact of pollution will be severe. Even more terrifying. In addition, the treatment method of highly infectious medical waste (highly infectious medical waste such as: used syringes containing viruses, bacteria and other organisms, gloves, surgically removed organs, etc.) is mostly packaged in plastic bags After that, outsourced processors are entrusted to handle the highly infectious medical waste. In the process of delivery, the packaging of highly infectious medical waste is likely to be broken due to external factors such as collisions, and the highly infectious medical waste is exposed, resulting in serious infection incidents. There are good and bad outsourced processors, and it is often heard that waste is piled up and discarded at will.

Detailed ways

The embodiment of the utility model will be further described below in conjunction with the accompanying drawings. As shown in the accompanying drawings, the highly infectious medical waste incinerator related to the utility model mainly includes a main combustion chamber 1, a secondary combustion chamber 2, and a control device 3 [figure not shown] and exhaust device 4 constitute, this secondary combustion chamber 2 is provided with several layers of porous mesh body 20, and is provided with heating element 21 between each layer of porous mesh body, this porous mesh system curve Made of refractory material, it has several interpenetrating mesh pores, so that the exhaust gas introduced from the main combustion chamber can enter the pores of the porous mesh body, and be divided into fine volumes for complete combustion. This secondary combustion chamber 2 has catalytic reaction air supply hole 22 [referring to Fig. 1, Fig. 2], is provided with a main combustion chamber 1 below, and this main combustion chamber 1 has a thermal cracking tank 10, and this thermal cracking tank 10 is airtight, There is a heating element 11 on its side, the upper end is connected to the secondary combustion chamber, and the lower end has an opening to set a material receiving cylinder 12, which is placed on a hearth 13 that can be moved outwards and lifted [displacement mechanism 130, lifting mechanism 131 is a known technology, please refer to Fig. 2], there are heating elements 11 and insufficient air supply holes 14 [referring to Fig. Place in the thermal cracking tank 10, and make the thermal cracking tank 10 form an airtight state, the exhaust device 4 has devices such as a flue heat exchange system 40, a dust collector 41, and an exhaust fan 42 [see Fig. 3 ]. After being treated by the secondary combustion chamber 2, the temperature of the flue gas is lowered, and then the dust is filtered by the dust collector 41 to ensure that the discharged gas is non-toxic, colorless, odorless, and dust-free. The highly infectious medical waste incinerator involved in the utility model must first heat the secondary combustion chamber 2 to the working temperature [such as 1200-1400°C], and then heat the main combustion chamber 1 to form a closed and insufficient supply. The method of measuring air makes the highly infectious medical waste in the material receiving cylinder 12 form anoxic combustion pyrolysis, and the flue gas produced by pyrolysis is introduced into the secondary combustion chamber 2, and after catalytic reaction, the air supply hole 22 is introduced into the required Air, catalytically introduced flue gas is completely combusted.

The following is a further description of the implementation steps of this creation:

1. Put the highly infectious medical waste into the material receiving cylinder 12 [at this time, the material receiving cylinder 12 is located outside the incinerator].

2. The displacement mechanism 130 sends the material receiving cylinder 12 into the furnace and closes the furnace door, and the lifting mechanism 131 lifts the material receiving cylinder 12 to position in the thermal cracking tank 10, and the thermal cracking tank 10 is in a closed state at this time.

3. Heat the secondary combustion chamber to the working temperature (such as 1200-1400°C).

4. Start the exhaust blower 42.

5. Heat the thermal cracking tank 10 to the working temperature (such as 800-1000°C), and introduce insufficient oxygen to form the thermal cracking of anoxic combustion [the secondary combustion chamber 2 needs to reach the working temperature before this program can be started. Can avoid like this because the secondary combustion chamber does not reach the complete combustion temperature, the flue gas of thermal cracking tank 10 cracking enters the secondary combustion chamber 2, so that cause the danger that is discharged without complete combustion].

6. The flue gas produced by pyrolysis is introduced into the secondary combustion chamber 2 for complete combustion.

7. The flue gas that has been completely burned in the secondary combustion chamber 2 is cooled down, and then the dust is filtered by the dust collector 41 [the non-combustible gas can be cooled and turned into carbon, which can be collected by the dust collector] to ensure that the discharged gas is free of dust. Toxic, colorless, odorless and dust-free.

8. After cooling down, lower the material receiving cylinder 12 and open the furnace door, remove the material receiving cylinder, and proceed to the next procedure after removing the ash.
