Explosion-proof dust remover

Abstract

The invention relates to an explosion-proof dust remover. A dust removal system comprises an air chamber, a fan, and a pipeline connected to the air chamber and the fan; the dust remover further comprises an explosion protection system and a real-time monitoring system; the explosion protection system comprises an explosion suppression device and an explosion venting device; the explosion suppression device mainly comprises a turning-plate explosion suppression valve and an explosion-suppression rotary discharge valve; the turning-plate explosion suppression valve is mounted on a dust inlet end pipeline, and the explosion-suppression rotary discharge valve is mounted in a discharge port of an air chamber ash bucket; the explosion venting device comprises an explosion venting plate and a flameless pressure relief device, and the explosion venting plate and the flameless pressure relief device are arranged on the wall of the air chamber; the real-time monitoring system comprises a PLC and a touch screen. The explosion-proof dust remover has the advantage that the explosion-proof dust remover can be used for dust removal in dust explosion environments, the operating state of the dustremover can be monitored in real time, the probability of explosion can be reduced effectively, and explosions can be isolated within certain areas in case of explosion to reduce damage to upstream personnel and equipment of the dust remover.

Description

technical field [0001] The invention belongs to the technical field of safety and dust explosion protection, in particular to an explosion-proof dust collector. Background technique [0002] In a system of interconnected equipment, a dust explosion within one equipment can propagate through the connected piping, creating increased turbulence, possibly causing some pre-compression, which then develops into a larger explosion within a connected piece of equipment. source of ignition. The effect of this combination enhances the violent intensity of the dust "secondary explosion" and increases the protection requirements of the system. Explosion-proof isolation is achieved through a protection system that prevents the explosion pressure wave and flame from propagating through connecting piping to other equipment or other areas of the plant. Isolation devices prevent the spread of flame and the effects of explosion pressure by providing complete isolation of the operation of th...

AI Technical Summary

Problems solved by technology

Although the explosion-proof dust collector can control the fan to stop running when danger occurs, although the safety is guaranteed, it will stop the fan operation as soon as a problem occurs, which will cause trouble to production
