A novel pyrolysis gasification furnace for organic solid waste

Abstract

The invention discloses a novel pyrolysis gasification furnace for organic solid waste. The furnace includes, in order from top to bottom, a furnace top, an upper furnace body, a lower furnace body, amulti-rotating water-cooled grate, and a slag discharge port, wherein the furnace top is provided with a feeding port and an atomizing spray structure; an upper side wall of the upper furnace body isprovided with an explosion-proof door, and the other side is provided with a gas outlet; the gas outlet is communicated with a cyclone separator; purified combustible gas is discharged from a purified gas outlet at the upper end of the cyclone separator; water separated by the cyclone separator is circulated to the atomizing spray structure and sprayed into the gasification furnace; and the sidewall of the lower furnace body is provided with a gas inlet, a multi-point multi-angle gas feeding structure and a gas outlet. The furnace has a simple structure, solves the problem that organic solidwaste gasification processes in the prior art are uneven in gasification, low in gasification efficiency, and high in tar content of combustible gas, and solves the problem that a water washing method which is adopted to remove tar oil at the rear end of a gas flue causes water pollution and waste of energy.

Description

Technical field: [0001] The invention relates to a novel organic solid waste pyrolysis gasification furnace. Background technique: [0002] Organic solid waste mainly includes domestic garbage, the organic part of industrial waste, and agricultural straw. How to realize "reduction, harmlessness, and recycling" of organic solid waste is an urgent problem to be solved. At present, organic solid waste is mainly treated by sanitary landfill and heat treatment. Sanitary landfill needs to occupy a large amount of land resources, and will also cause great pollution to the surrounding environment. The heat treatment method has gradually become one of the main treatment methods in large, medium and small cities. The heat treatment methods mainly include direct incineration and pyrolysis gasification. The incineration method meets the characteristics of reduction, harmlessness and resource utilization, but the incineration process will A large amount of pollutants are produced, and i...

Problems solved by technology

[0003] The purpose of the present invention is to provide a new type of organic solid waste pyrolysis gasification furnace, which solves the problems of uneven gasification, low gasification efficiency, and a large amount of tar in the combustible gas in the pyrolysis gasification process of organic solid waste in the prior art. It solves the problem that the water washing method at the back end of the gas flue to remove tar will only easily cause water pollution and waste of energy
