Abstract

The invention discloses a gasification treatment device for household refuse. Combustible materials in the household refuseare treated and processed into refuse derived fuel RDF, and the RDF is subjected to pyrolysis gasification of a fixed bed gasifier and purification into clean gas. The device comprises an RDF processing system, a gasification system and a gas purification system, wherein the RDF processing system comprises a discharge hopper, a plate feeder, a refuse breaker, a rotary screen, a magneticseparator, a dehydrator, a rotary dryer and a refuse press; the gasification system comprises a normal-pressure fixed bed gasifier, a feeding hole, a slag hole, a gas hole and a blower device; and the gas purification system comprises a cyclone dust collector, an electrical tar precipitator, a heat exchanger, a washer and an adsorption tower. The RDF is subjected to pyrolysis gasification of the fixed bed gasifier to form combustible gas, the combustible gas is purified by the gas purification system, and finally the gas is delivered to a gas holder through a Roots blower; the slag after the gasification is delivered to a brick making device for producing building materials; and wastewater generated by gas purification enters a wastewater tank for further treatment.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a domestic garbage gasification treatment device. Background technique [0002] Domestic garbage and other wastes in Chinese cities not only seriously pollute the living environment, but also cause a great waste of resources. According to statistics, the recovery rate of recyclable materials in domestic waste in China is only one-third to one-fourth of the average level of advanced countries in the world. [0003] In recent years, many enterprises at home and abroad have invested in the research of China's comprehensive urban waste treatment technology. However, due to technical limitations, the domestic waste treatment operation effect is not very good, and there are generally high investment, high cost, and high losses. The status quo of the "three highs". The level of industrialization is very low, and an enterprise group with a certain scale and efficiency ...
