Abstract

The invention discloses an environment-friendly treatment method for medical care waste. The environment-friendly treatment method comprises the following steps that S1, packaged medical waste is conveyed into a crushing mechanism from a feeding port through a medical waste transport vehicle, and manual carrying and contact with the medical waste are avoided; S2, the medical waste enters a cylinder body, and a second motor is started for crushing; S3, after S2, after pyrolysis of a first combustion chamber and reaction of a reaction chamber, air is introduced into a second combustion chamber,and combustible gas generated by pyrolysis enters the second combustion chamber to be fully combusted; S4, flue gas passing through a heat exchanger enters a dust removal mechanism through a dust removal pipeline, the flue gas contains a large amount of smoke dust, and the smoke dust is filtered through a dust removal filter element when passing through the dust removal mechanism; and S5, the fluegas subjected to dust removal enters an adsorption tower body, and acid gas in the flue gas is adsorbed by quicklime filler. The combustion efficiency is improved, the generation of dioxin is reduced, the emission of harmful gas is reduced, and the medical waste treatment is more environment-friendly.

Description

technical field [0001] The invention belongs to the field of medical waste treatment, in particular to an environmental protection treatment method for medical care waste. Background technique [0002] Medical waste refers to the medical waste generated during the medical rescue process, which contains a variety of germs and viruses. It is a hazardous waste that is extremely harmful to the environment and is highly infectious, corrosive and toxic. For the harmonious development of man and nature, the state attaches great importance to the harmless treatment of medical waste and promotes the construction of centralized treatment of medical waste. [0003] At present, in the treatment of medical waste, most of them use centralized combustion to kill bacteria and viruses through high temperature. However, the traditional direct combustion method, a large amount of medical waste is directly put into the incinerator, which cannot guarantee the full and complete combustion of medi...
