Gasifier for treating combustible components in household garbage

Abstract

The invention relates to a garbage combustible component gasifier, which comprises a material locking device, a material inlet, a furnace body, a furnace grate, a furnace grate driving device, a winddistribution port and the like, and is internally provided with a gasification chamber, wherein a material inlet and a gasified gas outlet are formed in the upper portion of the gasification chamber,the lower end of the gasification chamber is provided with a residue outlet, a gasification agent inlet and the rotary furnace grate for stirring and loosening, and a gas discharge port is connected with a gasification device and a cyclone dust collector through pipelines. According to the invention, the gasifier has advantages of high reliability, short gasification time, high efficiency, good effect, high energy utilization rate, low pollution, compact structure, convenient use and the like, and has good market prospects in garbage rear-end treatment.

Description

technical field [0001] The patent of the present invention provides a gasification device for treating combustible components of household garbage, especially suitable for gasification of combustible dry components after household garbage is mechanically treated by ultra-high pressure dry-wet separation. Background technique [0002] As a renewable resource, how to effectively integrate garbage to generate economic benefits. The recycling of waste resources has also been paid more and more attention by governments at all levels.

Problems solved by technology

[0005] Drawing on the experience of coal gasification, it is similar to the coal gasification device. The main gasification devices are divided into: fixed bed, circulating fluidized bed and entrained bed. The excess air coefficient of the fluidized bed is large, and the calorific value of the combustible gas collected in the later stage is low, which is not conducive to the post-processing of the combustible gas; the entrained bed has a high requirement for the particle size of the material, and the concentration of the fuel in the gasification medium is low and the reaction gas is not mixed. The heat exchange between solid particles and air flow is poor, and the gasifier is easy to coke if the gas outlet temperature is too high; while the fixed bed has wide adaptability to fuel, low sensitivity to slag coking, and the outlet temperature of combustible gas is relatively low. The purpose of gas purification
