Ash hopper anti-blocking and heating-free system for electrostatic and bag filter systems

Abstract

The invention belongs to the field of ash bucket blocking resistance of a static electricity and cloth bag dust removal system, and discloses an ash bucket anti-blocking and heat tracing-free system for the static electricity and cloth bag dust removal system. The system comprises a nanometer ceramic coating special for inner wall coating of an ash remover ash bucket. An anti-blocking machine is additionally arranged at an inlet of a fluidization air pipeline of the ash remover ash bucket. An electric charge quantity detecting and controlling system is mounted at the ash remover ash bucket. Astandby blocking clearing device is mounted on the outer wall of the ash remover ash bucket. A traditional heating and anti-blocking mode is replaced, energy consumption is little, high temperature resisting and corrosion resisting are achieved, abrasion resistance is high, sticking resistance is achieved, the service life is ensured to be as long as eight years after installation.

Description

technical field [0001] The invention belongs to the field of ash hopper anti-blocking of a dust removal system, in particular to an ash hopper anti-blocking and heat tracing-free system used in electrostatic and bag dust removal systems. Background technique [0002] The ash hopper anti-blocking of the current dust removal system often uses steam heating or electric heating to heat and keep the outer wall of the ash hopper to keep the high temperature of the ash hopper wall and prevent acid dew and water dew from forming compaction. [0003] The problem that prior art exists is: [0004] (1) The service life of the plate heating is short and the heating is unstable; the high energy consumption of steam heating, water leakage and other problems often lead to equipment accidents, causing coal ash to agglomerate and the ash hopper to flow unsmoothly. [0005] (2) The energy consumption of steam heating and electric heating is relatively large. [0006] High energy consumption...

AI Technical Summary

Problems solved by technology

[0004] (1) The service life of the plate heating is short and the heating is unstable; the high energy consumption of steam heating, water leakage and other problems often lead to equipment accidents, causing coal ash to agglomerate and the ash hopper to flow ash unsmoothly

[0005] (2) The energy consumption of steam heating and electric heating is relatively large

[0010] Whether it is plate type or steam heating, there are problems such as short life and unstable heating. There are often potential hidden dangers, and the daily maintenance also increases accordingly. Solving these problems greatly saves manpower and costs.
