Boiler dust removal system

Abstract

The invention relates to the field of waste incineration, in particular to a boiler dust removal system which is arranged in an incineration boiler, the incineration boiler comprises a boiler body and a smoke exhaust channel arranged on one side of the upper end of the boiler body, the dust removal system comprises a dust collection mechanism, and the dust collection mechanism is arranged in the smoke exhaust channel and comprises a plurality of cathode plates and anode plates which are vertically arranged and parallel to one another; the cathode plate and the anode plate are respectively connected with a power supply; a dust discharging opening for discharging collected dust is formed in the lower side wall of the smoke discharging channel; the cleaning mechanism is arranged in the smoke exhaust channel and is used for cleaning dust on the cathode plate to the lower side in the smoke exhaust channel; the collecting mechanism is arranged on the lower side of the smoke discharging channel and used for collecting dust discharged from the dust discharging opening. The dust removal device has the effects of reducing adverse effects on the dust removal function of the boiler and prolonging the service life of components so as to improve the stability of the dust removal effect.

Description

technical field [0001] This application relates to the field of waste incineration, in particular to a boiler dust removal system. Background technique [0002] The way to deal with domestic waste is generally to generate electricity through incineration to achieve full utilization of resources. When incinerating waste, the general use of waste incineration boilers includes a furnace body, and a row is connected to one side of the upper end of the furnace body. Smoke channel, the flue gas generated during the waste incineration process is discharged through the smoke exhaust channel and subjected to subsequent purification treatment; before the flue gas is discharged for purification or waste heat recovery process, it is necessary to filter the dust mixed in the flue gas; currently The dust mixed in the flue gas is generally filtered by using a bag filter, and a pulse type dust removal device is set up with the dust bag to realize the filtration and removal of the dust in th...

AI Technical Summary

Problems solved by technology

[0003] In view of the related technologies mentioned above, the inventor found that: using the solution of bag dust removal, the pulse type dust removal device used when removing the dust adsorbed on the dust bag is The air compressor is used as the driving force, and the air compressor will have great instability due to power and power supply when it is spraying air. In simple terms, the air flow from the air compressor is unstable, which will cause the working pressure of the dust bag increase, it is easy to cause damage to the dust bag, shorten the service life of the components, and adversely affect the dust removal project of the dust removal system
