Medical waste incineration programme
First, the types and characteristics of medical waste:
1. Disposable syringes, infusion sets, cotton yarns, surgical treatments, residual limbs, rubber gloves, protective clothing, etc.
2. CDC, blood bags from bloodstream, infectious and hazardous bed supplies.
3. Dangerous medical waste generated by a major epidemic.
4. The calorific value of mixed medical waste is generally 3500Kcal/kg-4180Kcal/kg.
Second, the working principle of the incinerator:
WSL series medical waste incinerator adopts the most advanced one-stage pyrolysis gasification + surround wind co-firing + secondary incineration + burn-out incineration method. The design of the primary combustion chamber of the incinerator uses the gasification incineration technology to change the temperature inside the furnace of the incinerator from 200 ° C to 400 ° C. The waste does not cause problems such as frit, slag, and sintering during the incineration process. At high temperatures, the combustible gas in the flue gas can be fully burned, and the gas generated by the gasifier can be efficiently mixed with the air to prevent the carbon material in the gas flame from escaping and late burning. When the flue gas enters the high-temperature burnout chamber, the combustion mode is adopted such as tangential entry and tangential entry of the combustion-supporting air, so that the flue gas can be fully combusted again in the burn-out chamber, and the flue gas is removed by the swirling airflow, and the flue gas is incinerated. The residence time in the furnace is more than 2 seconds, so that the combustible gas in the flue gas and the combustible material in the fly ash are completely incinerated, and the dry exhaust gas purification device is arranged in the upper part of the incinerator, and hydrogen chloride, sulfur oxide, etc. generated in the incineration are generated. The adsorption treatment is performed, and components such as odor in the flue gas are decomposed at a high temperature. The flue gas purification system is provided with a calcium hydroxide filter brick and an acid gas for neutralization reaction, thereby achieving the purpose of adsorbing acid gas and purifying exhaust gas. Reduce harmful components in the flue gas to below the national “Hazardous Waste Incineration Pollution Control Standard (GB18484-2001)” and other standard values.
The operation control of the incinerator adopts automatic program control, which reduces the labor level of the workers. The design of the incinerator door and the cleaning door adopts a fully sealed structure in the form of a mother-in-the-mouth. When incinerated, the furnace is completely isolated from the outside of the furnace to form a negative pressure. Burning eliminates the possibility of secondary pollution.
third. WSL series medical waste incinerators have the following characteristics compared with similar products:
1. Using gasification and incineration technology, it is suitable for medical equipment such as incineration syringes, drip containers, and various types of paper waste materials, bandages, absorbent cotton, various medical wastes, and various wastes excluded by hospitals and medical institutions.
2. Three-dimensional structure, small size, small footprint, compact structure and low requirements for supporting facilities.
3. The combustion mode of the aero-engine is used to make the flue gas tangentially enter the high-temperature burnout chamber and the combustion-assisted air tangentially enter and other combustion modes, so that the flue gas can be fully burned again in the burn-out chamber, and the flue gas is used for dust removal.
4. The gasification and incineration method is adopted to prevent the problem of frit, sintering and the like in the process of incineration of medical waste. The garbage generated every day can be incinerated at one time.
5. Using technologies such as gasification and incineration, mixed incineration, and burn-out treatment, so that the smoke and dust content of the exhaust gas can meet the national emission standards.
6. Use a fully enclosed operation. The incinerator door and the cleaning door are all in the form of a mother-in-the-mouth, fully sealed structure, completely isolated from the outside world when incinerated, forming a negative pressure combustion, suitable for treating infectious medical waste and avoiding secondary pollution.
Treatment plan
First, the design basis of medical waste incinerator:
1. "Drug Control Standard for Medical Hazardous Waste Incineration" (GB18484-2001)
2. "Standards for Pollution Control of Domestic Waste Incineration" (GB18485-2001)
3. Technical Requirements for Medical Waste Incinerators (GB19218-2003)
4. "Dangerous Waste Landfill Pollution Control Standards" (GB18598-2001)
5. Regulations on the Administration of Medical Waste (Order No. 380 of the State Council)
Second, the design principles:
1. After the medical waste is disposed, the user's required discharge standard is reached.
2. The incineration process is simple, the equipment runs reliably, and the treatment effect is good.
3. The project has less one-time investment, small floor space, simple operation management and low operating cost.
