Problems solved by technology

Coking in fluidized bed boiler coupling coal disposal will block the air distribution plate hood and slag discharge pipe, resulting in uneven fluidization of air distribution and poor slag discharge, affecting the normal operation of the boiler
At present, there is no mature solid waste coupling incineration boiler in the industry that can realize the long-term disposal and operation of industrial solid waste. There is no effective solution to the problem that solid waste is easily coked by metal impurities.

Abstract

The invention discloses a winnowing impurity removal and incineration disposal device for industrial solid waste. The problems that at present, no mature solid waste coupling incineration boiler can realize long-period treatment operation of industrial solid wastes, and the solid wastes are prone to being coked due to metal impurities are solved. The winnowing impurity removal and incineration disposal device comprises a solid waste bin (1), an air separator (3), a coal bucket (9), a fluidized bed incinerator (10), a cyclone separator (11), a material returning device (12), a flue vertical shaft (13), a dust remover (15) and a chimney (16). The solid waste bin is connected with a solid waste inlet in the lower part of the air separator; a gas-solid outlet of the air separator is connected with a solid waste inlet of the lower conical section of the fluidized bed incinerator; and a smoke outlet in the upper part of the fluidized bed incinerator is connected with a smoke inlet of the cyclone separator, a coarse ash outlet is formed in the bottom of the cyclone separator and connected with an inlet of the material returning device, and an outlet of the material returning device is connected with a material returning opening formed in the lower conical section of the fluidized bed incinerator. The winnowing impurity removal and incineration disposal device is used for winnowing impurity removal and incineration treatment of industrial solid waste.

Description

technical field [0001] The invention relates to the field of solid waste disposal, in particular to a wind separation, impurity removal and incineration disposal device for industrial solid waste. Background technique [0002] With the development of society and economy, the output of industrial solid waste is increasing year by year. Industrial solid waste generally has a high content of heavy metals and cannot be directly landfilled. At the same time, some industrial solid waste contains high calorific value and can be used. The utilization of resources has become an urgent problem to be solved. At present, industrial solid waste is mainly incinerated by waste incinerators or fluidized bed boilers coupled with coal-fired disposal. However, since industrial solid waste will inevitably bring in metal impurities such as iron wire screws when it is put into the furnace, incineration and disposal of industrial solid waste, especially Textile scraps, shoe scraps, and rubber are...
