Intelligent experimental demonstration device for fire damp explosion

Abstract

The invention relates to a demonstration device for the intelligent gas explosion experiment, which effectively solves the problems that the gas explosion can not be completely and accurately demonstrated and whole explosion process formed by the gas concentration, the temperature, oxygen and the like is different to be controlled. The demonstration device adopts the structure that tracks are arranged in an analog laneway on a control cabinet; an air and gas inlet, a gas and temperature sensor, a heater, an oxygen sensor and a discharger are arranged between the tracks in sequence; a digital display is arranged at the rear part on the control cabinet; a gas pump, a gas storage tank, a reducing transformer, the heater and the discharger are arranged in the control cabinet; the discharger and the heater are respectively connected with the reducing transformer; the reducing transformer, a direct current stabilized voltage supply, a second electropneumatic valve, a first electropneumatic valve and a gas pump are connected in parallel and connected with a power source; the gas storage tank is arranged between the first electropneumatic valve and the gas pump; and the first electropneumatic valve is communicated with the air inlet. The demonstration device has the advantages that gas explosion can be effectively prevented, heavy accident can be prevented, and the economic benefit and the social benefit are great.

Description

Intelligent Gas Explosion Experiment Demonstration Device 1. Technical field The invention relates to a coal mine gas explosion prevention device, in particular to an intelligent gas explosion experiment demonstration device. 2. Technical Background Gas explosions, like coal dust explosions, are major disasters in mines. In recent years, the safety situation in coal mines across the country has been severe, with frequent serious accidents. Coal mine safety work is related to the interests of the country and the people, the party's ability to govern, and the The party and the state have always attached great importance to social stability and harmony. In order to further strengthen the safety awareness education of employees, various gas explosion experimental demonstration devices have been developed in mines so that more employees can understand the hazards of gas and the power of explosions. Make them operate in strict accordance with the rules and regulations in the fut...

Problems solved by technology

In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide an intelligent gas explosion experiment demonstration device, which can effectively solve the problem of incomplete and accurate demonstration of gas explosion, and the explosion caused by gas concentration, temperature, oxygen, etc. The technical solution to the problem that the whole process is difficult to control is to include a transparent simulated tunnel and a control cabinet. There are rails in the transparent simulated tunnel above the control cabinet, and there are gas inlets, gas inlets, gas sensors, Temperature sensor, platinum wire heater, oxygen sensor and high-voltage tip discharger. There is a digital display on the top and rear of the control cabinet. The front of the control cabinet is equipped with barometer, working status indicator light, air pump power switch and main power switch. There are air pump, gas storage tank, step-down transformer, platinum wire heater and high-voltage tip discharger, the high-voltage tip discharger and platinum wire heater are respectively connected with step-down transformer, step-down transformer, DC stabilized power supply, second The electromagnetic gas valve, the first electromagnetic gas valve and the air pump are connected in parallel, and are connected to the power supply through the main power switch. There is an air storage tank between the first electromagnetic gas valve and the air pump, and the first electromagnetic gas valve is connected to the gas inlet.
