Fluidized bed industrial solid waste incinerator adopting tubular air distribution and working method thereof

Abstract

The invention discloses a fluidized bed industrial solid waste incinerator adopting tubular air distribution and a working method thereof, and belongs to the technical field of solid waste disposal. The lower part of a furnace body is a conical section, a solid waste inlet and a material returning inlet are formed in the conical section, the solid waste inlet is connected with a feeding system, and the material returning inlet is connected with a material returning device; a smoke outlet is formed in the upper portion of the furnace body and connected with a separation device, a bottom outletof the separation device is connected with the material returning device, and an upper outlet of the separation device is connected to a tail flue; a bottom slag outlet in the bottom of the conical section is connected with a slag falling pipe and is provided with a slag discharging valve; a plurality of layers of fluidization air distribution pipes are arranged in the conical section and are connected with a fluidization air system; gaps for slag falling are reserved between the adjacent fluidization air distribution pipes and between the fluidization air distribution pipes and the wall surface of the conical section; and a plurality of air outlet holes are formed in the fluidization air distribution pipes. The industrial solid waste incinerator is reasonable and flexible in structural design, particularly suitable for industrial solid waste disposal, high in application value and easy to industrialize.

Description

technical field [0001] The invention belongs to the technical field of solid waste disposal, and in particular relates to a fluidized bed industrial solid waste incinerator adopting tubular air distribution and a working method thereof. Background technique [0002] With the development of urban industry, the output of industrial solid waste is increasing year by year. How to properly dispose of these solid wastes has become a research hotspot in the industry at this stage. Industrial solid waste generally has a high content of heavy metals, and it is not feasible to directly landfill it. At present, it is mainly processed through the coupling and co-processing of various industrial kilns, among which fluidized bed boilers are more widely used to process industrial solid waste for power generation. The solid waste is put into the fluidized bed boiler together with the coal fuel, and the high temperature environment in the furnace is used to realize the solid waste combustion...

AI Technical Summary

Problems solved by technology

However, in the existing practice of solid waste treatment, the following problems have arisen: the solid waste contains iron wires, screws and other sundries. If it is not sorted clean when entering the furnace, it is easy to mix with scraps such as cloth strips and leather after entering the furnace. Coking blocks the wind cap of the air distribution plate and adversely affects the operation of the boiler
