Ash hopper device capable of accurately judging and relieving accidental ash deposition of ash separator

Abstract

The invention provides an ash hopper device capable of accurately judging and relieving accidental ash deposition of an ash separator. The ash hopper device comprises a hopper body and an ash discharging pipeline, wherein the hopper body is provided with a designed bearing ash level and a high-ash-level prewarning ash level, and the ash discharging pipeline is provided with an ash inlet pipe extending into the hopper body and a detecting port extending out of the hopper body; the opening of the ash inlet pipe is located between the designed bearing ash level and the ash hopper high-ash-level prewarning ash level; and the detecting port can be sealed through a sealing assembly capable of being opened and closed. Whether an ash separator ash hopper is in a normal state or in an abnormal state can be conveniently judged at the detecting port; and moreover, deposited ash can be discharged through the detecting port after the ash separator designed stored ash bearing capacity is exceeded and after the amount of the ash in the ash hopper is more than normal ash storage amount, and the protective function to the ash separator is achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to dust removal equipment, and in particular to an ash hopper device which can accurately judge and alleviate accidental dust accumulation of 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 been many saf...

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
