Medical waste classifying and high-temperature pyrolysis treatment system

Abstract

The invention discloses a medical waste classifying and high-temperature pyrolysis treatment system. The medical waste classifying and high-temperature pyrolysis treatment system comprises a classified collecting device, a manual sorting platform, a high-temperature sterilizing device, a primary smashing device, a sorting device, a secondary smashing device and a high-temperature pyrolysis treatment device, wherein medical waste raw materials mainly treated by the system are preliminarily selected through the classified collecting device and the manual sorting platform; and then the medical waste is classified through a magnetic separator, a wind separator and a gravity washbox, the separated magnetic metal, aluminum, glass, gravel and the like can be treated by a recycle department, recycling of useful materials in the medical waste is realized, and the separated waste with high content of other organic matters is converted into an available energy form through the high-temperature pyrolysis treatment. According to the medical waste classifying and high-temperature pyrolysis treatment system, the reduction of wasting of resources is facilitated, and the system has the characteristics of a high reducing quantity degree, low secondary pollution and high energy recovery.

Description

technical field [0001] The invention relates to a sorting recovery and treatment system of medical waste, in particular to a sorting recovery and high-temperature pyrolysis treatment system of medical waste. Background technique [0002] Environmental and development issues have become the focus of global attention. As a prominent environmental issue, waste disposal, especially the disposal of hospital waste, has attracted more and more attention from the whole society and people in the industry. With the continuous progress and development of society, with the With the continuous emergence of various new diseases, new technologies and medicines are constantly being produced, and the types and quantities of medical waste are undergoing great changes. Especially in densely populated areas, the treatment of medical waste is particularly important. . [0003] However, the vast majority of medical waste has not been scientifically treated. With the widespread use of disposable ...

Problems solved by technology

[0003] However, the vast majority of medical waste has not been scientifically treated. With the widespread use of disposable medical supplies, the output of solid waste in hospitals has increased; in order to save costs, some units often mix medical waste with domestic waste for disposal. , while disposable infusion sets, surgical resections, used gauze, pharmaceutical waste residue, blood and other wastes in medical waste contain a large number of harmful substances such as pathogenic microorganisms and parasites, which are highly infectious and require professional treatment. Segregation and special incineration treatment must not be mixed with ordinary domestic waste. If it is not handled properly, it will definitely cause secondary infection and environmental pollution, and pose a serious threat to the environment and human health.

[0004] With people's recognition of the strong pollution and virality of medical waste, coupled with the flammability and high calorific value of medical waste, people began to incinerate medical waste to generate electricity. Although this method can use the calorific value in waste to provide people It brings convenience, but the toxic gases produced by medical waste, such as sulfide and dioxin, make people unbearable, and it is difficult to remove the toxic substances in medical waste only by burning, and the gas and waste produced by incineration are still harmful to the environment. There are "sequelae" of pollution, so there are special machines for medical waste treatment: high-temperature incinerators, that is, medical waste incinerators, such as grate incinerators in the United States; circulating fluidized beds in Japan, Spain, France, and Germany grate furnaces in Canada; rotary furnaces in Switzerland and domestic medical waste rotary grate furnaces; however, this treatment method still cannot completely eliminate the toxicity of medical waste, and the generation of dioxins still cannot be solved; at the same time, due to the high temperature The tar produced is very easy to block the furnace pipe, which has a great impact on the maintenance of the equipment.
