Gasifier and household refuse harmless gasification energy process thereof

Abstract

The invention discloses a gasifier, which is provided with, from bottom to top, a secondary gasifier and a first gasifier in superposing arrangement. The first gasifier is provided with a feed inlet and a carrier gas port; the external vertical direction of the first gasifier is provided with a motor; the output shaft of the motor extends into the first gasifier is provided with a plurality of tray layers; the inner wall of the first gasifier is provided with a plurality of heating element groups; a passage between the first gasifier and the second gasifier is provided with a one-way conveyor belt; the side surface of the second gasifier is in communication with a cyclone dust collector; and a medium inlet is arranged on the second gasifier. The invention also discloses a household refuse harmless gasification energy process; the gas produced by the invention has high calorific value achieving 4080Kcal/Nm<3>; the gas produce production does not produce tar; and the household refuse does not need classification treatment and can be directly sent into the process cycle, so as to dramatically reduce the amount of equipment, labor costs and energy consumption.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, and in particular relates to a gasification furnace and a harmless gasification energy process method for domestic waste. Background technique [0002] Household garbage refers to solid waste generated in daily life or activities that provide services for daily life and solid waste that is regarded as garbage by law and administrative law. Its components mainly include kitchen waste, waste paper, fabric, plastic, rubber, metal, waste electrical appliances, glass and muck. With the increase in the number of cities and the expansion of their scale, the annual production of domestic waste in my country has increased rapidly. The problems of land occupation and environmental pollution caused by the sharp increase in the amount of garbage are also becoming more and more prominent. The huge amount of domestic garbage poses a great threat to the ecological environment of the city and surr...

AI Technical Summary

Problems solved by technology

However, a large amount of acid gas, incompletely burned organic components, dust, ash and other substances will be produced during the incineration process. If the necessary treatment is not carried out, it will inevitably cause serious secondary pollution. Among them, dioxins and heavy metals are harmful to the environment. Very harmful to the ecological environment and human health, HCl, NOx, SO 2 Acidic gases are also the main cause of acid rain

And because of the low calorific value of domestic waste, it is easy to cause low power generation efficiency, or it can only be used for coal power generation

[0007] In addition, there is a device on the market called a biomass gasifier, which is mainly used for the biomass gasification process. There is no example for the gasification of domestic waste, and it generally has a low calorific value of the gasification gas, and the acidity of the gasification gas is low. advanced questions
