Explosion-proof dust collector and explosion-proof control method

Abstract

Provided are an explosion-proof dust collector and an explosion-proof control method. The explosion-proof dust collector comprises a dust collector body (3) for collecting combustible dust, an inerting gas injection system, a detection system for detecting CO concentration and / or temperature and a control system, wherein the inerting gas injection system includes buffer tanks (11), control valves (1), one-way valves (4), inerting dust-proof spray heads (2) and an external inerting gas supply system. The explosion-proof control method comprises the following steps that when the detection system detects that the internal temperature of the dust remover body (3) rises to a set value, or detects that the CO concentration is higher than a set value, the control system controls the inerting gas injection system to be automatically started for running or a worker starts the system; after the inerting gas injection system is started, inerting gas is sprayed into the inerting dust-proof spray heads (2) located at the top of the dust remover body (3), then the control system controls the inerting dust-proof spray heads (2) at the top to reduce the injection rates of the inerting gas, and inerting gas is sprayed into the inerting dust-proof spray heads (2) at the bottom.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to an explosion-proof dust collector and an explosion-proof control method. Background technique [0002] The dust removal device is equipment equipped in many production industries. Its function is to collect and remove the dust at the dusty place, thereby reducing the amount of dust discharged into the atmosphere. It is an important environmental protection equipment to improve environmental pollution and air quality. The mixture of combustible dust and air in the dust removal device will explode if it is ignited or encounters an ignition source within the explosion range. If the deposited dust heats up and spontaneously ignites, it will become the ignition source of the explosion, causing an explosion; an explosion impacts the dust layer, forming a dust cloud, and causing a secondary explosion of the dust. Dust explosion will cause safety accidents and economic losses to pr...

AI Technical Summary

Problems solved by technology

Although it can solve the problem that the existing dust collector is easy to cause explosion and poor safety

However, it is easy to cause the dust collector to stop running due to environmental deterioration when dust removal is required. After a fire occurs, there is no active fire extinguishing device, which is not conducive to safe production.
