Intelligent-control explosion suppression apparatus for dust explosion prevention of dry dedusting system

Abstract

The invention provides an intelligent-control explosion suppression apparatus for dust explosion prevention of a dry dedusting system. The apparatus comprises an air suction pipeline, a dry deduster,a dust explosion suppression spark detecting device, a gas content monitoring device, an explosion suppressant low-pressure jet device, an explosion suppressant high-pressure jet device and an intelligent-control explosion suppression system for dust explosion prevention. Each of the explosion suppressant low-pressure jet device and the explosion suppressant high-pressure jet device is provided with a digital control solenoid valve and a flow rate digital controller. The apparatus simultaneously performs data signal monitoring on the spark energy, the oxygen content and the carbon monoxide inthe air suction pipeline and transmits the data to the intelligent-control explosion suppression system for dust explosion prevention, the intelligent-control explosion suppression system for dust explosion prevention performs logical digital intelligent selection and automatically triggers a digital signal of the corresponding magnitude to intelligently turn on the corresponding digital control solenoid valve, and a corresponding magnitude of an explosion suppressant is instantaneously and continuously jetted and released in an intelligent control state, so the dust explosion accidents of thedry dedusting system are actively prevented.

Description

technical field [0001] The invention relates to the dust explosion-proof field of a dust removal system, in particular to a dust explosion-proof intelligent control explosion suppression device for a dry dust removal system. Background technique [0002] The dry dust removal system is a dust removal equipment commonly used in the processing and manufacturing of industrial products to capture and purify the dust generated. Industrial product materials such as metal, wood, cotton, grain, rubber, coal, and petrochemical products etc., its materials produce combustible and explosive dust during the product processing and manufacturing process, and the combustible and explosive dust is captured and entered into the dry dust removal system, which is subject to the dust concentration of the dust explosion, the oxygen content and carbon monoxide content in the dust gas, and the spark that ignites the dust. Factors such as energy and the relevant index parameters that constitute the ...

AI Technical Summary

Problems solved by technology

The technical method of inertization measures requires a large amount of inert powder or inert gas to be continuously injected into the dry dust removal system. The problem is that the high cost, and the use of a large amount of inerting powder increases a large amount of solid waste at the same time, and the use of a large amount of inerting gas also increases a large amount of waste gas emissions, causing pollution to the environment
