Plasma continuous gasifying and splitting treatment device for medical waste

Abstract

The invention discloses a plasma continuous gasifying and splitting treatment device for medical waste. The device comprises a gasifying and splitting furnace. A gasifying and splitting furnace body is vertically arranged, a first plasma torch, a feed port, an ash outlet and an air replenishing port are formed in the gasifying and splitting furnace body, a first push rod is arranged at the position of the feed port, and a closed ash outflow device is arranged at the position of the ash outlet. Intermittent operation is changed into continuous feeding, residues are continuously discharged, andthe operation is convenient; with the help of the characteristics of high temperature and high energy of plasma torches, under the assisting effect of air, the medical waste is completely treated; gasifying and splitting are carried out in a reducing atmosphere, synthesis gas is generated for secondary combustion, and low Nox is generated; and the plasma torches can completely destroy a dioxin generation precursor, and generation of dioxin is avoided.

Description

technical field [0001] The invention relates to the technical field of hazardous waste treatment, in particular to a plasma continuous gasification and cracking treatment device for medical waste. Background technique [0002] Although the current medical waste disposal industry has achieved rapid development, many problems are still exposed. At present, there are many medical waste disposal technologies in my country: [0003] (1) The high-temperature incineration method is suitable for all kinds of medical waste. After incineration, the volume and weight of the waste are significantly reduced, the sterilization and pollutant removal effects are good, and the technology is mature, but the construction and operation costs are high, and dioxins will be generated. Toxic substances and other harmful gases; [0004] (2) High-pressure steam sterilization has low investment, low operating costs, and low risk of residues, but it is prone to odor, may cause air pollution emissions...

AI Technical Summary

Problems solved by technology

[0003] (1) The high-temperature incineration method is suitable for all kinds of medical waste. After incineration, the volume and weight of the waste are significantly reduced, the effect of disinfection and pollutant removal is good, and the technology is mature, but the construction and operation costs are high, and dioxins will be generated. Toxic substances and other harmful gases;

[0004] (2) High-pressure steam sterilization has low investment, low operating costs, and low risk of residues, but it is prone to odor, may cause air pollution emissions, and medical waste must be shredded to a size smaller than 50mm;

[0006] The current gasification cracking method is mostly intermittent gasification cracking, which has problems such as small processing capacity, poor operation stability and low cracking efficiency, which restricts the application of gasification cracking technology in medical waste
