Device for suppressing gas explosion and application method for device

Abstract

The invention discloses a device for suppressing gas explosion and an application method for the device, and belongs to devices and methods for suppressing gas explosion of coal mines. The device comprises a sensor assembly, a controller, a compressed air control switch, an ejector, an extinguishing agent container and a U-shaped water tank; and the sensor assembly is connected with an input end of the controller by a data line, an output end of the controller is connected with the compressed air control switch, the compressed air control switch is mounted at a compressed air inlet of the ejector, the ejector is connected with the extinguishing agent container by a pipeline, and the U-shaped water tank is connected onto a water inlet of the extinguishing agent container. The controller is used for receiving signals of a flame sensor, a temperature sensor and a pressure sensor and issues action commands to the compressed air control switch; one end of the extinguishing agent container is connected with a receiving chamber, and the other end of the extinguishing agent container is connected with the U-shaped water tank; foam extinguishing agents are sucked into the receiving chamber of the ejector, and compressed air is mixed with the foam extinguishing agents in a mixing chamber, so that foam is formed; and the extinguishing agents are ejected via a nozzle towards explosion flame and extinguish the explosion flame.

Description

technical field [0001] The invention relates to a device and method for suppressing coal mine gas explosion, in particular to a device for suppressing gas explosion and its application method. Background technique [0002] Coal is the main energy source in my country and currently accounts for 70%-75% of my country's primary energy production and consumption structure. The country's "Energy Medium and Long-Term Development Plan (2004-2020)" points out that my country implements "an energy strategy with coal as the main body, electric power as the center, and comprehensive development of oil, gas and new energy." Coal will still be the dominant energy in our country for a long period of time at present and in the future. In the past five years (2005-2009), coal mine accidents accounted for 72.8%-86.3% of the serious accidents in industrial and mining enterprises with more than 10 deaths. Therefore, coal mine safety production has always been a major issue in the development ...

Problems solved by technology

[0004] However, in actual use, the use of explosion-proof booths has the following disadvantages: the water in the sink is easy to volatilize and needs to be added regularly; the salt is easy to wet and agglomerate, which weakens the fire extinguishing effect; the installation accuracy is high, and the action is sensitive and easy to be lifted under small vibrations Flip, when the movement is insensitive, the best time to form water mist or rock powder cloud area will be missed
