Agent for rapidly removing high sulfur coal mine underground hydrogen sulfide gas, and device thereof

Abstract

The invention belongs to the field of coal mine production safety. A purpose of the present invention is to solve the problem of high sulfur coal mine underground hydrogen sulfide so as to ensure the safe production of coal mine. The present invention discloses an agent for rapidly removing the high sulfur coal mine underground hydrogen sulfide gas. The agent adopts sodium carbonate as an alkaline absorbent, and is characterized in that: the agent further comprises a chloramine-T adopted as a catalytic oxidizing agent; the sodium carbonate and the chloramine-T are prepared into a solution according to a sodium carbonate mass fraction of 0.15-0.3% and a chloramine-T mass fraction of 0.3-0.5%. The invention further discloses a device for rapidly removing the high sulfur coal mine underground hydrogen sulfide gas. The device comprises four parts of a hydrogen sulfide sensor (1), a sensing switch (2), an alarm device (3) and a mist sprayer (4), wherein the agent described in the claim 1 is stored in the mist sprayer. With the device, the absorbent can be dispersed into particles with the extremely small particle sizes, such that the agent adequately contacts the hydrogen sulfide gas so as to improve the absorption efficiency.

Description

[0001] technical field [0002] The invention belongs to the field of coal mine production safety, and aims to solve the problem of hydrogen sulfide protruding underground in high-sulfur coal mines, so as to ensure the safe production of coal mines. [0003] Background technique [0004] During the mining of coal mines, especially high-sulfur coal mines, a large amount of hydrogen sulfide (H 2 S) gas, H 2 S is a highly toxic flammable gas, colorless, with the smell of rotten eggs, its density is 1.19 times that of air, it is easily soluble in water to form hydrogen sulfuric acid, and its solubility in water is CO 2 2.7 times of CH 4 93 times more. h 2 S is both an irritating gas and a corrosive gas. h 2 S concentration at 0.4mg / m 3 People can clearly smell its odor; 70~150 mg / m 3 When inhaled for a few minutes, olfactory fatigue will occur without smelling the odor. The higher the concentration, the faster the olfactory fatigue, and the easier it is to make people...

Problems solved by technology

[0006] The above treatment methods are generally used for low-concentration H 2 The treatment of S, for the solution of underground H in high-sulfur coal mines 2 The outburst problem of S has great application limitations, and there is no solution for the outburst H in mines. 2 Related reports on S gas treatment, so coal mine H 2 The rapid control of S prominence is a difficult problem faced by many mines today. It is of great significance to develop a method for quickly removing hydrogen sulfide gas under the mine to ensure the safe and efficient production of coal mines.
