Multifunctional integrated gasifier with rotary furnace core air supply and simple scraper ash removal

Abstract

The multi-functional integrated gasification furnace with rotary furnace core air supply and simple scraper ash removal relates to the field of environmental protection technology. The core of the present invention is the use of a rotary air supply furnace core, and the combustion and gasification interface of waste is a rotary furnace core The surface of the cone body is embedded on the refractory layer of ceramic air supply nozzles instead of on the metal furnace chassis, thus greatly improving the operating life of the metal furnace chassis. The ash scraper is installed on the furnace chassis, the ash receiving tray is arranged under the furnace chassis, and the closed ash falling tank is set on one side of the ash receiving tray, and the screw conveyor is installed at the bottom of the ash dropping tank, and the collected furnace ash is transported to the ash furnace for throwing. The entrance of the ashes improves the environmental protection of the equipment operation and improves the working environment.

Description

technical field [0001] The invention relates to the field of environmental protection technology, in particular to a multifunctional integrated gasifier with a rotary furnace core for air supply and a simple scraper for ash removal. Background technique [0002] With the continuous growth of the global economy and the acceleration of urbanization, the incremental production of medical waste, other hazardous waste and domestic waste and the resulting environmental pollution and human health problems have become common problems facing the world. Therefore, the ultimate goal of solid waste treatment and disposal is to realize the harmlessness, reduction, and resource utilization of solid waste. [0003] Gasification is a thermochemical disposal process between incineration and pyrolysis. It can react the organic components in the waste with the gasification agent in an oxygen-deficient atmosphere to generate synthesis gas, while the inorganic components are removed in the form...

AI Technical Summary

Problems solved by technology

However, there are still many deficiencies in the common solid waste gasification process and the design of the gasifier structure

For example, the traditional gasification fixed bed tends to form a local high temperature zone at the place where the air is injected and where the combustion is intensive, resulting in uneven temperature distribution and high temperature sintering, which affects the normal operation of the gasifier

Generally, there are no movable parts inside the gasifier, so it is difficult to improve and solve the problems of uneven temperature distribution and high temperature sintering

Furthermore, most gasifiers feed materials from the side wall of the furnace, which easily leads to uneven accumulation of materials, causing "bridging" in the material layer, and affecting the normal operation of the gasifier.
