Harmless gasification treating process for medical waste

Abstract

The invention discloses a harmless gasification treating process for a medical waste. By the process, the water content of a biomass gasification auxiliary material is less than 40 percent, and the particle diameter is controlled to be between 0 and 10mm. The treating process comprises the following steps of: mixing the medical waste with the biomass gasification auxiliary material in volume ratio into a mixture, wherein metal and glass are removed from the medical waste and the medical waste is subjected to solid-liquid separation, adding the mixture into a medical waste treating gasification furnace at the speed of 1 to 50kg/h, operating a balance wheel to compress the mixture, covering a top cover, opening an exhaust pipe and a valve which is arranged on a primary air supply pipe, closing a valve on a secondary air supply pipe, starting a fan, and adjusting the temperature of the medical waste treating gasification furnace; and when flue gas which contains much and steam is exhausted, closing a valve on an exhaust pipe, opening a valve of the secondary air supply pipe, filtering crude gas generated by the medical waste treating gasification furnace through a silk bamboo net in a purified gas conveying pipe, and conveying purified gas into a gas burning tower. The treating process for the medical waste can perform harmless gasification treatment on the medical waste, saves transportation cost and treatment cost, and is obvious in social benefit and environment-friendly benefit.

Description

technical field [0001] The invention relates to a gasification treatment process, in particular to a harmless gasification treatment process for treating medical waste (garbage) in the medical industry, belonging to a method for harmless treatment of hazardous waste. Background technique [0002] At present, the harmless treatment of medical waste (also called medical waste) collected by various medical institutions (especially large and medium-sized hospitals) is a worldwide problem. The traditional treatment method (or process) is to incinerate medical waste, incinerate The direct result of medical waste (garbage) is to seriously pollute the environment (because the smoke contains hazardous substances) and waste resources. Although the decision of the government department is to establish a centralized treatment center for medical waste, the treatment method is still incineration. This method, which can cause secondary pollution to the environment, is unacceptable to ordin...
