Medical waste separation, recovery, and incineration processing method

Abstract

The invention relates to medical waste separation, recovery, and incineration processing method, comprising the following steps: 1. waste collection: collecting by adopting an enclosed way; 2. separation: the chunk material and bulk material which can be recycled separately are separated out; 3. smashing: all the material being processed collectively is smashed under the enclosed condition; 4. sterilization: all the smashed material is sterilized; 5. sorting: the medical waste is divided into two categories in a mechanical way according to the proportion of the material, the first is lighter material with the main ingredients being fiber and other organics, and the second is heavier material with the main ingredients being metal, sandrock and other mineral substances, the lighter material is dried and smashed to form incineration material; and 6. incineration: coal power is added into the incineration material as a combustion accelerator and fuel oil is sprayed into an incineration furnace as a second combustion accelerator. The invention is conducive for reasonable utilization of material in the medical waste and the reduction of energy consumption.

Description

technical field [0001] The invention relates to a method for classified recovery and incineration treatment of medical waste, which is mainly used for the recovery and final treatment of medical waste and other infectious and harmful waste. Background technique [0002] For infectious solid wastes such as medical waste, people have adopted a variety of methods to deal with them. The main technical direction is to incinerate, and the microorganisms will be completely decomposed by incineration, so that they are no longer infectious. For example, China No. 200510048910.8 The patent application discloses a circulating fluidized bed incineration method for medical waste. Limestone is used as the inert bed material of the circulating fluidized bed. Calcium oxide generated by burning limestone at high temperature is combined with hypochlorous acid in medical waste and pyrolysis incineration. The neutralization reaction of acid gases such as hydrogen chloride produced in the incine...

AI Technical Summary

Problems solved by technology

This method can effectively solve the infectious problem of medical waste, but due to the use of incineration, it also brings problems such as fuel consumption, loss of recyclable materials, and air pollution. Garbage treatment process, the process includes the following steps: the first step, the medical waste is sent to the comprehensive processor through the garbage conveying device, and sealed; the second step is to deliver steam with a temperature of The pressure rises to 4-8 atmospheres, and the holding time is 20-50 minutes; the third step is to open the garbage discharge device at the lower end of the comprehensive processor, so that the medical waste enters the collector in a closed manner, and the steam is discharged from its chimney; the fourth step, The medical waste in the collector is sent to the sorting machine by the conveying mechanism; the fifth step is to sort out the metals and batteries in the medical waste; the sixth step is to transport the sorted medical waste to the shredder for crushing; Seven steps, transport the crushed garbage to the disposal site

Since this method firstly performs high-temperature steam sterilization, and then sorts to a certain extent, metals that can be recycled are recovered and incineration is not suitable for batteries, which improves the combustion characteristics of materials to a certain extent, but the final treatment is still through Incineration treatment, problems caused by incineration still exist
