Device capable of conducting judgment and safe, easy and convenient dust discharging on accident accumulated dust of dust remover

Abstract

The invention provides a device capable of conducting judgment and safe, easy and convenient dust discharging on accident accumulated dust of a dust remover. The device comprises a dust hopper arranged in the dust remover and a dust discharging pipeline; the dust hopper is provided with a design bearing material level and a high material level early warning material level; a dust inlet pipe is arranged on the upper portion, extending into a hopper body, of the dust discharging pipeline, and the lower portion, extending out of the hopper body, of the dust discharging pipeline is vertically arranged; a pipe opening of the dust discharging pipeline is located between the design bearing material level and the high material level early warning material level; and a pipe opening of the lower portion of the dust discharging pipeline is sealed through a valve. The situation that the dust hopper of the dust remover is in a normal state or an abnormal state can be conveniently judged at a detection opening, after the dust remover designed dust storing bearing capacity is exceeded and dust in the dust hopper is higher than the normal dust storing quantity, the accumulated dust can be discharged through an automatic dust discharging safety valve, and the dust remover is automatically protected.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to dust removal equipment, and in particular to a device capable of judging and safely and conveniently releasing dust from accidental dust accumulation in dust collectors. Background technique [0002] The ash hopper of the dust collector equipped in the thermal power plant is often due to ash discharge failure, and the phenomenon of short-term dust accumulation in the ash hopper often occurs, which is a normal phenomenon. Correspondingly, within the time frame of returning to normal dust removal, there will be no harm to the dust collector. Therefore, the cases where dust accumulation in the dust hopper of the dust collector caused harm to the dust collector were all due to untimely troubleshooting, which made the dust accumulation in the dust hopper of the dust collector exceed the storage capacity allowed by the design of the dust collector. [0003] There have...

AI Technical Summary

Problems solved by technology

However, in the harsh environment in the dust hopper of the dust collector, false alarms and damage to the radio frequency admittance level switch are still unavoidable. misleading

In addition, the radio frequency admittance level gauge needs to be debugged before use. During debugging, it needs to go through two states of ash and no ash to accurately calibrate the level gauge. In this way, there are defects in the ash removal system of the dust collector, such as ash removal When the designed conveying capacity is insufficient and the airflow distribution of the dust collector is uneven, there will be great risks and hidden dangers in the operation of the ash removal system

However, for passive nuclear level gauges, there is also the possibility of failure due to failure. In addition, passive nuclear level gauges have not been tested and verified under emergency conditions, so even if passive nuclear level gauges are used instead The radio frequency admittance material level switch cannot completely avoid the serious dust accumulation hazard of the dust collector
