Dust explosion prevention integration system

Abstract

The invention provides a dust explosion prevention integration system. The system comprises a main control unit, an explosion suppression system, an explosive-proof system, an explosion venting systemand a spark detection and fire extinction system. The explosive-proof system comprises a mechanical automatic explosive-proof system, a passive two-way explosive-proof valve and a passive one-way explosive-proof valve. The explosion venting system comprises an explosion venting sheet, a flameless venting device and a spring-type flameless venting valve. The main control unit is connected with theexplosion suppression system, the mechanical automatic explosive-proof system and the spark detection and fire extinction system and controls the explosion suppression system, the mechanical automatic explosive-proof system and the spark detection and fire extinction system, and the explosion suppression system and the explosive-proof system or the explosion venting system can be combined for use. The dust explosion prevention integration system mainly adopts the explosion suppression system, the mechanical automatic explosive-proof system, a two-way passive explosive-proof system, the explosion venting system and the spark detection and fire extinction system and adopts proper safeguard procedures for explosion prevention on the basis of existing danger zones with dust explosion and thelike.

Description

Technical field [0001] The present invention relates to the technical field of dust explosion protection, and in particular, to a dust explosion protection integrated system. Background technique [0002] With the rapid development of industry today, the potential danger of dust explosions is greatly increased. When mixed with air during processing, handling or storage operations, the explosion will cause the ignition of combustible gas, mist or dust, and rapid pressure rise in closed structures At the same time, if there is not enough strength to withstand the deflagration pressure, it will cause heavy losses and casualties. With the increasing number of powder explosion accidents, it will bring huge losses to the industry, and even far exceed the harm caused by fire. According to the guidance of international standards such as NFPA68, NAPA69, and NFPA654, for the safe production of industry, the safety of people and equipment, and the uncertainty of explosion, we must raise the...
