Abstract
The invention falls into the field of coal mine production safety, aims to solve the problem of hydrogen sulfide leaking in high-sulfur coal mine so as to ensure the safety production of coal mine. The invention also discloses a device for rapidly removing hydrogen sulfide gas in high-sulfur coal mine. The device includes a hydrogen sulfide sensor (1), an inductive switch (2), a warning device (3) and a mist sprayer (4), wherein the medicine chest of the mist sprayer is stored with medicament. The device can disperse the absorbent into particles with very tiny particle size, to facilitate the full contact between the medicament and the hydrogen sulfide gas, so as to improve the absorption efficiency.
Description
Technical field
The utility model belongs to the coal mine production safety field, is intended to solve hydrogen sulfide distinct issues under the sulphur coal mine, to guarantee the safety in production in colliery.
Background technology
Coal mining is especially in the recovery process in high-sulfur coal ore deposit, and outstanding or mine water is gushed out suddenly and produced a large amount of hydrogen sulfide (H with gas
2S) gas, H
2S is a kind of fuel gas of severe toxicity, and is colourless, has the rotten egg smell, and its density is 1.19 times of air, very easily water-soluble formation hydrosulphuric acid, and its solubility in water is CO
22.7 times, be CH
4More than 93 times.H
2S is a kind of irritative gas, also is a kind of corrosive gas.H
2S concentration is at 0.4mg/m
3The time, the people can obviously smell its stink; 70～150 mg/m
3The time, sucking and promptly olfactory fatigue took place in several minutes and can't smell stink, the high more olfactory fatigue of concentration is fast more, and the people is lowered one's guard; Surpass 760 mg/m
3The time, pulmonary edema, bronchitis, pneumonia can take place in the short time, possibly cause life danger; Surpass 1000 mg/m
3, it is dead to cause people's appearance of shocking by electricity.According to statistics, H
2The number that S poisons is at the 4th of China's malicious number of the infected placed in the middle, and death toll occupies the 2nd.Simultaneously, H
2S is to Corrosion of Metallic Materials property also entail dangers to device security.
H
2S is one of colliery toxic and harmful, but H
2The existence of S can not show a candle to methane (CH
4) general, H does not appear in present most of mine
2S gas or H
2S content is very low, does not influence the safety in production of mine, therefore, and to H
2The study on prevention degree of depth of S and range are far away to CH
4Research.The H that former Soviet Union Ma Kai Prokofiev safety of coal mines research institute occurs in promptly beginning some collieries, Dun Basi mining area in early 1950s
2S studies, and aspect preventing and treating, has set up some measures.The H that China began Western Hills colliery, Xinjiang in 1958
2S studies and administers; H to Hebi mineral bureau four ore deposits in 1966
2S studies and administers, and has all obtained effect preferably.Main prophylactico-therapeutic measures both domestic and external at present has the ventilation of increasing and sprays alkaline solution.
Above-mentioned improvement method generally is used for low concentration H
2The improvement of S is for solving H under the sulphur coal mine
2The outstanding problem of S has very big application restriction, does not have as yet at present to the down outstanding H of mine
2The relevant report of S master gas, so colliery H
2The outstanding quick control of S is the difficult problem that current a lot of mine is faced, and the method for developing hydrogen sulfide gas under a kind of quick removal mine has very significant meaning to the safe and efficient production of guaranteeing the colliery.
The utility model content
The purpose of the utility model be to develop a kind of can be fast, the equipment of efficient absorption hydrogen sulfide gas.
The equipment of hydrogen sulfide gas under a kind of quick removal sulphur coal mine of the utility model, said equipment comprises hydrogen sulfide sensor (1), inductive switch (2), warning device (3) and atomizing sprayer (4) four parts;
Said atomizing sprayer has its work of inductive switch control;
The action of said hydrogen sulfide sensor control inductive switch and warning device;
Said hydrogen sulfide sensor is provided with the concentration limit of hydrogen sulfide under the mine, and when concentration surpassed the restriction of sensor settings, sensor started the automatic warning of warning device and the control inductive switch makes atomizing sprayer in running order; When the Air Hydrogen Sulfide gas content was reduced to safe concentration, hydrogen sulfide sensor control atomizing sprayer quit work;
Store medicament in the said atomizing sprayer medicine-chest.
Further, said atomizing sprayer (4) is provided with a subsequent use medicine-chest.Subsequent use medicine-chest can make amendment when machine breaks down and replace timely.
Further, the spray amount of said atomizing sprayer (4) is 2.5L/min; The atomizing distance is 15-20m.Above-mentioned preferred parameter be according to the concentration of hydrogen sulfide gas under the sulphur coal mine, area etc. make preferred; Medicament is dispersed into the extremely small particle of particle diameter, make medicament can be rapidly fully and hydrogen sulfide gas reacts and make hydrogen sulfide gas be able to remove fast.
The equipment of the utility model adopts induction spraying automatically, and the water curtain or the pipe network that replace in the past spray facility, the equipment simple and flexible, and control atomizing sprayer work automatically through sensor, but the very first time takes measures to the outstanding accident of hydrogen sulfide.This equipment can be dispersed into the extremely small particle of particle diameter with absorbent, impels medicament fully to contact with hydrogen sulfide gas, has improved absorption efficiency.

The specific embodiment
Embodiment 1
1) hydrogen sulfide sensor is placed the simulation tunnel, setting sensor upper limit of concentration value is 800ppm, and lower limit is 6.6ppm, and formulating vulcanization hydrogen absorption liquid 18L places in the explosive box, but the explosive box the using and the reserved.
2) hydrogen sulfide gas is regulated via pressure-reducing valve decompression, flowmeter and is got into the simulation tunnel; Through the concentration of hydrogen sulfide in control flow and the time adjusting boiler-plate; It is raise gradually, and when concentration surpasses alarm limit definite value 800ppm, the autoalarm on the sensor begins to report to the police; Close the hydrogen sulfide gas cylinder immediately and stop air inlet; Atomizing sprayer was opened automatically and was sprayed this moment, and spray amount is 1.5L/min, and hydrogen sulfide sensor stops atomizing sprayer work automatically when concentration of hydrogen sulfide is reduced to 6.6ppm in the simulation tunnel.
Equipment is placed under the coal mine, and setting sensor upper limit of concentration value is 20ppm, and lower limit is 6.6ppm, and the preparation absorption liquid places in the explosive box.Concentration of hydrogen sulfide surpasses upper threshold value 20ppm in underground air, and device is reported to the police automatically, and atomizing sprayer is started working; The atomizing flow is 1.5L/min; Atomizing is apart from 15-20m, and the underground work personnel can control the atomizing orientation, guarantees no dead angle in the zone; When Air Hydrogen Sulfide content is reduced to safety standard concentration and following, atomizing sprayer quits work automatically.
