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.

Abstract

An explosion-proof dust collector and an explosion-proof control method, comprising a dust collector body (3) for collecting combustible dust, an inert gas injection system; a detection system for detecting CO concentration or / and temperature; a control system; the inert gas injection system includes a buffer tank (11), control valve (1), check valve (4), inerting dust-proof nozzle (2), external inerting gas supply system, and the explosion-proof control process includes the following steps: When the detection system detects that the dust collector body ( 3) When the internal temperature rises to the set value, or when the CO concentration is detected to exceed the set value, the control system controls the inert gas injection system to start automatically, or the staff starts the system; after the inert gas injection system is started, it is located The inerting dust-proof nozzle (2) on the top of the dust collector body (3) sprays inert gas; then the control system controls the inert dust-proof nozzle (2) on the top to reduce the injection speed of the inert gas; Spray inert gas into the anti-dust nozzle (2).

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...
