Spraying fire extinguishing equipment prepared through gel, manufacturing method thereof and gel spraying method

Abstract

The invention relates to spraying fire extinguishing equipment prepared through gel, a manufacturing method for the spraying fire extinguishing equipment and a gel spraying method. The spraying fire extinguishing equipment prepared through the gel comprises a solvent tank, a gel raw material box, a solvent conveying pipe and a discharging pipe, wherein non-polar solvent is accommodated in the solvent tank; gel raw materials are accommodated in the gel raw material box; one end of the solvent conveying pipe stretches to the bottom of the solvent tank, the other end of the solvent conveying pipe stretches inside the gel raw material box, the solvent conveying pipe comprises a conveying pipe valve, and the conveying pipe valve is located between the solvent tank and the gel raw material box and is used for controlling the non-polar solvent to flow into the gel raw material box from the solvent tank; one end of the discharging pipe stretches to the bottom of the gel raw material box, the other end of the discharging pipe is a discharging outlet used for discharging a mixture of the gel raw materials and the non-polar solvent, the discharging pipe is provided with a discharging pipe valve, and the discharging pipe valve is used for controlling discharging of the mixture and is close to the discharging outlet. In a stationary state, the conveying pipe valve and the discharging pipe valve are in closed states, the pressure P1 of gas in the gel raw material box is larger than external pressure, and the pressure P2 of gas in the solvent tank is larger than P1.

Description

technical field [0001] The present invention relates to the technology of coal seam fire prevention and control, more specifically, to the spray fire extinguishing equipment prepared by gel, the method of spraying gel by using the spray fire extinguishing equipment prepared by gel and the manufacturing method of fire extinguishing equipment prepared by gel. Background technique [0002] The use of gel fire extinguishing for coal seam fires has the following advantages: fast speed, good effect, and can effectively prevent water gas explosions that are prone to occur when water extinguishing fires. At present, many mines use electric-powered automatic glue injection equipment to directly mix powdered polymer colloid fire extinguishing agent with water to form a gel, which is injected into coal seams for fire prevention and fire extinguishing. However, when a coal mine fire occurs, the power supply is often interrupted, which brings difficulties for using the equipment to quick...

AI Technical Summary

Problems solved by technology

However, when a fire occurs in a coal mine, the power supply is often interrupted, which makes it difficult to use the equipment to quickly inject glue to extinguish the fire.

At present, there is no automatic fire extinguishing device for spraying polymer gel
