Description

A movable high-temperature plasma medical waste disposal shelter and disposal method

technical field

The invention belongs to the technical field of medical waste disposal, and particularly relates to a movable high-temperature plasma medical waste disposal shelter and a disposal method.

Background technique

At present, the output of medical waste in my country is increasing continuously, because of its characteristics of scattered distribution, small output and complex composition, and medical waste is classified as hazardous waste, which is highly infectious and dangerous. The gradually stricter sanitation management regulations and the public's increasing concern about infectious diseases have made the harmless and reduced disposal of medical waste more and more important.

For some special hospitals, such as infectious disease hospitals, when the medical waste generated is transferred to the medical waste treatment center for processing, it will pose a great threat to the life and health of the personnel during the entire transfer process. Therefore, it is necessary to develop a device for on-site disposal of medical waste, which is regularly transported to the site for treatment. At the same time, if a public health incident breaks out in a short period of time, due to the exponential surge of medical waste in the hospital in a short period of time, when the centralized medical waste treatment capacity of the local area is exceeded, a medical waste disposal system with mobile capability can greatly solve the above-mentioned problems. problem.

At present, there are few medical waste disposal system products with mobile capability, and the main technical routes adopted are as follows:

(1) High temperature cooking and sterilization technology

This technology kills bacteria, viruses and living substances in the medical waste through high-temperature cooking of the medical waste, and turns it into general waste and then undergoes secondary treatment in other ways. Although this technology can achieve the purpose of sterilization and inactivation, it has no function of reducing the amount of medical waste, and even the addition of water during the cooking process further increases the volume and weight, requiring secondary treatment; at the same time, cooking will cause medical waste. It emits a great odor, causing harm and discomfort to the surrounding people; at the same time, a large amount of waste water is produced, and the waste water with medical drugs flows into the ground, causing serious secondary pollution.

(2) Microwave sterilization technology

This technology sterilizes medical waste by microwave. Similar to the high-temperature retort sterilization technology, it can only sterilize medical waste, but cannot reduce its weight, and requires secondary disposal. In addition, limited by the small space of the mobile system, the volume of the power supply for microwave disposal is often restricted to a certain extent, so the power cannot be very large, so there will be insufficient microwave penetration capability for large medical waste, and even lead to Waste germs close to the interior cannot be killed.

(3) Incineration technology

Incineration technology is currently a method of incinerating medical waste through rotary kiln and other incineration equipment and using diesel burners. The advantage of this technology is that it can reduce and sterilize medical waste. made progress. But its disadvantage is that due to the low combustion temperature (generally below 1000 ℃), the processing speed is slow, and a large amount of air is introduced into the combustion process, which will produce a large amount of harmful gases such as dioxin, furan, nitrogen oxides, etc. The surrounding people are healthy; at the same time, some macromolecular inorganic substances cannot react effectively, and a large amount of smoke and odor will be generated after being directly discharged, affecting the normal life and production nearby.

performing water quenching recovery on the inorganic matter molten slurry by adopting a slag dragging device;

the micromolecule gas passes through the second combustion chamber section to be combusted secondarily, so that high-temperature flue gas is obtained;

after the high-temperature flue gas is subjected to quenching deacidification treatment, dedusting treatment and denitrification treatment in sequence, clean tail gas is obtained and is discharged through a chimney.
