Medical garbage sorting recovery and harmless treatment method

Abstract

The invention relates to a medical garbage sorting recovery and harmless treatment method, comprising the following steps: (1) garbage collecting: adopting to a sealed way to collect garbage; (2) sorting: separating the chunk materials and the bulk materials which can be recycled separately; (3) crushing: crushing all the materials needed to be treated together in a sealing condition; (4) radiation sterilization: sterilizing all the crushed materials by radiation; (5) separating: according to the specific weight and magnetism of materials, separating the medical garbage into four types by a mechanical way: lighter materials, heavier materials, magnetic materials and residual materials; (6) burning and recycling: recycling the lighter materials, the heavier materials and the magnetic materials and burning the residual materials by sending the materials into a special garbage incinerator. The invention facilitates recycling of physical resources and reduces energy consumption and air pollution.

Description

technical field [0001] The invention relates to a method for classified recovery and harmless 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 incinerato...

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 cru...
