System and method for treating medical waste through cooperation of high-temperature cooking and pyrolysis incineration

Abstract

The invention provides a medical waste high-temperature cooking and pyrolysis incineration treatment system which is characterized in that a high-temperature cooking subsystem comprises a high-temperature cooking batch feeder, a sterilization device, a high-temperature cooking treatment pot, a drain tank and an alkali liquor tank; the pyrolysis incineration subsystem comprises a pyrolysis incineration batch feeder, a pyrolysis incinerator, a waste heat boiler, a deacidification tower and a dust remover; a high-temperature steam conveying pipeline is arranged between the waste heat boiler and the high-temperature cooking treatment pot; an atomizer at the top of the deacidification tower is communicated with the bottom of the alkali liquor tank through an alkali liquor conveying pipeline. In addition, the invention further provides a method for treating the medical waste through cooperation of high-temperature cooking and pyrolysis incineration. According to the medical waste high-temperature cooking and pyrolysis incineration synergistic treatment system and method, full utilization of resources and energy in the medical waste pyrolysis incineration and high-temperature cooking process can be achieved, the investment of the medical waste treatment system is reduced, the treatment cost of waste liquid and waste gas is reduced, and wide application and popularization prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of medical waste treatment, and in particular relates to a high-temperature cooking collaborative pyrolysis incineration treatment system and method for medical waste. Background technique [0002] Medical waste refers to the directly or indirectly infectious, toxic and other hazardous waste produced by medical and health institutions in medical treatment, prevention, health care and other activities. Medical waste, pharmaceutical medical waste and chemical medical waste. With the development of my country's medical industry, medical waste is also increasing. Especially after the outbreak of some infectious diseases, the production of highly infectious medical waste such as protective clothing, masks, daily necessities for patients from designated hospitals and isolation points has surged. If medical waste cannot be treated scientifically, it may cause disease spread or related public health problems, threa...

AI Technical Summary

Problems solved by technology

However, high-temperature cooking technology is only suitable for treating infectious and damaging medical waste, and the disposal process requires external steam supply, and the odorous steam and liquid produced at the same time still need to be treated separately

[0004] Pyrolysis incineration technology is suitable for the disposal of most medical wastes, and the disinfection and sterilization are thorough. In the existing incineration disposal process, waste heat boilers are mostly used to exchange heat and cool down the incineration flue gas, but the amount of high-temperature steam generated after heat exchange by waste heat boilers is small And the parameters are low, neither can meet the steam demand of the generating set, nor is it suitable for long-distance transportation and use, most of them are directly discharged outside, and cannot be rationally utilized

In addition, the pyrolysis and incineration disposal of medical waste must be equipped with a flue gas purification system, which has a relatively high operating cost
