Embodiment Construction

[0056] see figure 1 , figure 2 , this gas and other combustible gas explosion early warning method of the present invention is that a plurality of monitoring points are selectively determined in the mine area to be tested, each monitoring point is provided with a gas and other combustible gas explosion early warning device, and the sampling air flow main pipeline 1 of the device is There is an isolation chamber 5 and a combustion chamber 6 inside, and the gas distribution system injects gas gas into the combustion chamber 6 regularly and quantitatively. The gas flow sensor, pressure sensor 18 or temperature sensor collects the data of detonation time and injected gas volume, enters the control circuit board 12, performs data processing, and obtains a safety degree assessment, and the output is respectively connected to the alarm circuit 20, the safety control center, and the safety system network. 21. Start the emergency plan and corresponding safety system control equipment...

Abstract

The invention discloses a method and a device for early warning the explosion of gas and other combustible gases. A plurality of monitoring points are arranged in a mine area; and the explosion early warning device of the gas and other combustible gases is arranged. A sampling air current main pipeline of the device is internally provided with an isolation chamber and a combustion chamber; an airdistribution system is used for injecting the gas into the combustion chamber at the fixed time and fixed quantity; an electronic ignition system can be used for simultaneously and continuously igniting at fixed time through an electronic ignition head until the combustion and the explosion occur; an electrical control system is used for acquiring the explosion time and injecting gas quantity data and enters a control circuit board for data processing to obtain safety degree estimation; and the output is respectively connected with an alarm circuit, a safety control center and a safety systemnetwork and is used for starting an emergency response plan and corresponding safety system control equipment. By adopting a brand new method and a device, the condition that the combustible gas is ultralimit can be quickly found by continuously testing the dynamic data of the mixed combustible gas, early warned in advance, and quickly handled, thereby avoiding the heavy losses of life and property of people.

Description

Technical field: [0001] The invention relates to a safety early warning method and device, in particular to an early warning method and device for quickly testing and discovering and timely early warning and disposal of underground gas and other combustible gas explosions in mines. Background technique: [0002] For a long time, there have been a series of major safety accidents involving flammable gas hazardous explosion industries, especially underground gas explosions in coal mines, causing mass casualties and injuries, resulting in the heaviest losses and very bad social impact. According to gas characteristics, as long as the minimum content reaches 5% and the oxygen content is sufficient (the national mine safety law stipulates that the underground oxygen content should not be lower than 20%), it can be detonated and burned at any time; while white phosphorus can spontaneously ignite at a temperature of more than 40 degrees. Biogas can also spontaneously ignite when ex...
