Material-distributing device for refuse pyrolysis gasification furnace

Abstract

A material-distributing device for a refuse pyrolysis gasification furnace is arranged between a hydraulic feeder and a feeding port of the pyrolysis gasification furnace. According to the material-distributing device for the refuse pyrolysis gasification furnace, a transmission screw is flatly placed on a cylindrical transmission tooth and connected with a material-distributing mesh screen through a transmission pulley, the material-distributing mesh screen is of a cone frustum type and is placed above the feeding port of the pyrolysis gasification furnace, the middle of the material-distributing mesh screen is provided with a feeding port and a material-distributing outlet, and the edge of the material-distributing mesh screen is provided with a plurality of mesh screen holes. The material-distributing device is suitable for material distribution of refuse derived fuel (RDF) and can achieve the integrated operation process of material feeding and material distribution and improve refuse pyrolysis gasification quality.

Description

technical field [0001] The invention belongs to the field of solid waste treatment, and in particular relates to a material distribution device for a garbage pyrolysis gasifier. Background technique [0002] At present, there are four main ways to deal with urban waste in various countries in the world: landfill, composting and incineration, and pyrolysis and gasification. Landfill treatment covers a large area, and the leachate and odorous gas produced by it will cause serious secondary pollution to the soil, groundwater and surrounding air environment, and damage the ecological environment; composting technology requires pre-treatment of garbage, requiring high organic matter The composting process needs to occupy a large area of ​​land, and at the same time, polluting gases and leachate will be produced. Improper treatment will cause serious environmental pollution; the essence of incineration is to oxidize organic waste into inert waste under high temperature and suffici...

Problems solved by technology

[0003] The feeding form of the existing pyrolysis gasification furnace is mainly to feed directly by the feeder. This method is likely to cause uneven feeding, and wind pockets have appeared, causing this part of the garbage to be burned directly instead of pyrolysis and gasification. In addition, it is ventilated In bad places, "raw material area" is prone to appear, resulting in incomplete pyrolysis and gasification of waste
