Fluidized grain dust removing system

Abstract

The invention provides a fluidized grain dust removing system which comprises a charging hopper, a material storage pot, a screwed feeder and a material even mixing pot which are sequentially connected from the top down and fixed on a steel bracket, wherein a cylinder body of the material storage pot is divided into an upper part and a lower part, the upper part is cylindrical, and the lower part is of an inverted cone shape; an upper sealing head of the material storage pot is connected with an outlet of the charging hopper through a pipeline, and a lower sealing head of the material storage pot is connected with an inlet of the screwed feeder through a pipeline; an outlet of the screwed feeder is connected with the top of the material even mixing pot; the upper part of the material even mixing pot is cylindrical, while the lower part is of the inverted cone shape; the top end of material even mixing pot is connected with one end of a main air pipe, while the other end of the main air pipe is connected with an air compressor, and a material loosing air pipe is also led out from the main air pipe; and the bottom end of the material even mixing pot is connected with one end of a material conveying pipeline, while the other end of the material conveying pipeline is connected with a front smoke box of a boiler. The system can mix fine sand with air so as to enable the fine sand to be fluidized and has simple manufacturing process, strong controllability, high safety, good stability, ideal dust removing effect as well as convenient use and maintenance.

Description

technical field [0001] The invention relates to a fluidized particle ash removal system for shell-type waste heat boilers in the chemical industry. Background technique [0002] The dust and dust removal equipment on the heating surface of the boiler is one of the important equipment to improve the thermal efficiency of the boiler and prolong the service life of the equipment. There are various methods and equipment for boiler dust removal. For example, the gas pulse dust removal system uses the sound wave and air pulse technology with a certain pressure generated by the instantaneous combustion of combustible gas. It has the advantages of high strength, good dust removal effect, and convenient use. Unsafe hidden dangers that are not easy to find; at the same time, the mixing ratio of combustible gas and air is required to be high, and the amount of combustible gas used is large, otherwise there will be a situation where it is not clear; in addition, there is a defect that ...

AI Technical Summary

Problems solved by technology

In the utilization of high-temperature flue gas waste heat in the chemical industry, the high-temperature flue gas entering the waste heat boiler often contains a large amount of viscous dust particles. Due to the strong adhesion between particles, the viscous particles are easy to agglomerate and adhere to the furnace wall of the boiler and heat On the surface, it will greatly affect the heat transfer effect and operation safety of the boiler
