Abstract

The invention discloses a waste gasification treatment system, comprising a feed system for pretreated materials and a gasification furnace, a solid discharge port at the bottom of the gasification furnace and a sorter; an exhaust gas at the upper part of the gasification furnace The port is connected with the provided gas dedusting equipment, and the screened solid particles are sent back to the gasification furnace through the gas dedusting equipment; the product gas is stored in the provided gas storage tank; the gasification furnace includes It includes a feed area, a reaction area and a cooling area from top to bottom; on the inner wall of the reaction area, there are multiple fire protection modules for detecting the temperature of the inner wall, and the fire protection modules are arranged in a ring around the axis of the gasifier to form an annular firewall . Also disclosed is an automatic temperature control method for gasification power generation. After the system is in normal operation, the high temperature sensor inserted in the refractory brick detects the current temperature of the refractory brick in real time. And automatically adjust according to the set or detected maximum temperature as a reference, so as to achieve the effect of temperature control.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, and in particular relates to a garbage gasification treatment system and an automatic temperature control method thereof. Background technique [0002] Garbage is solid waste generated in human daily life and production. Due to the large amount of discharge, complex and diverse components, and polluting, resourceful and social nature, it needs harmless, resourceful, reduction and socialized treatment. If not handled properly, it will pollute the environment, affect environmental sanitation, waste resources, destroy production and living safety, and disrupt social harmony. Garbage disposal is to quickly remove garbage, and conduct harmless treatment, and finally make reasonable use of it. The garbage disposal methods widely used today are sanitary landfill, high temperature composting and incineration. The purpose of garbage disposal is harmless, resourceful and reduction. [0003...
