Rapid and active fire-extinguishing system for combustible dust

Abstract

The invention provides a rapid fire-extinguishing control system for combustible dust. The rapid fire-extinguishing control system structurally comprises detectors, a controller, a drive gas source, a rapidly-opening mechanism, a water storage bottle, a pressurization pump and a rapidly-opening valve for an explosion venting diaphragm, wherein the detectors are distributed in indoor spaces and connected with the controller through buses; a display panel and a sound-light alarm are arranged on the controller which is connected with a display control terminal through a bus; the controller is connected with the rapidly-opening mechanism on the drive gas source, the rapidly-opening mechanism is arranged on a connection pipeline of the drive gas source and the water storage bottle, the water storage bottle is connected to a main pipeline in parallel, and the pressurization pump is connected to one branch at the middle of the main pipeline through a check valve; the rapidly-opening valve for the explosion venting diaphragm is arranged at the tail end of the main pipeline; and branch pipelines and nozzles are controlled through the rapidly-opening valve for the explosion venting diaphragm. The invention provides a fully-submerged water mist raining fire-extinguishing explosion control system carrying out high-speed detection and starting spraying, and the system is used for actively and rapidly preventing the combustion and explosion of the combustible dust.

Description

technical field [0001] The invention relates to a fire extinguishing control system, in particular to a combustible dust rapid fire extinguishing control system. Background technique [0002] At present, the traditional fire-fighting deluge system is mainly used for combustible dust fire control and explosion control technology; the deluge system can be divided into two types: empty pipe deluge system and water-filled deluge system. The fire extinguishing speed of the water-filled deluge system is faster than that of the empty pipe deluge system. In practical application, the appropriate form can be selected according to the requirements of the protected object. First of all, the fire detection methods of traditional deluge systems are mostly temperature sensing, smoke sensing, video analysis, etc. combined with manual control modes, and the response time for fire and explosion detection is too long; there is a lack of reliable pipeline air tightness monitoring and water sho...

AI Technical Summary

Problems solved by technology

First of all, the fire detection methods of traditional deluge systems are mostly temperature sensing, smoke sensing, video analysis, etc. combined with manual control modes, and the response time for fire and explosion detection is too long; there is a lack of reliable pipeline air tightness monitoring and water shortage monitoring , basically fail for high-speed combustion and explosion

Secondly, the vertical deluge system usually has a dry pipe network and belongs to the empty pipe deluge system. The structure of the system is relatively simple, but when the water source pressure is unstable, it is prone to malfunction and cause unnecessary damage to production. Loss: The rain system sprays fire extinguishing water from the open nozzle, which has a large volume and a drop diameter of more than one centimeter, so the weight is high, the landing is fast, the suspension cooling time is too short, the fire extinguishing effect is poor, and there are too many fire extinguishing blind spots
