Abstract
The present invention relates to a compressed air breathing device for refuge and rescue in gas disaster. Once gas bursts or explodes in a high biogas mine or a burst gas mine, oxygen in the air suddenly drops so that operation staff die because of suffocation. The present invention provides an underground collective gas refuge and rescue device for mines so that once disaster occurs, people can use the device to safely breath and eat food, and call for help and contact with people on the ground, and the device can be used as rescue equipment as well as equipment for ' close covering shooting operation '. The device is composed of two sets of filter pressure regulating wind distributors (4), a safety sealing cabin (9), pressure relief resistant valve (1), an elastic positive pressure mask(10), etc. so that compressed air completely meets the requirements of the respiration of human bodies after pressure reduction, pressure stabilization, and multi-stage filtration and purification. The present invention has the operating cost lower than that of a disposable self-rescuer, is favourable to improve the safety and the work efficiency of mine operation, and increases economic benefits.
Description
The present invention is relevant with the self-rescuer that the miner uses, and the gas that belongs to the miner is taken refuge and the lifesaving field.
Especially the mine of containing gas under the mine, sometimes emerge a large amount of gas suddenly, the field operation personnel are poisoned, in case run into Mars, will cause gas explosion, airborne oxygen concentration is sharply descended, be lower than 16% and will cause personnel's faintness that suffocates, if rescue untimelyly, accident will cause death.
When outstanding the and explosion accident of above-mentioned gas takes place, often follow the down-hole ventilation equipment to be damaged, form the long-time large tracts of land air pollution that continues,, will cause a tremendous loss of lives as no shelter and lifesaving measure and the effective gas equipment of saving oneself.
The outstanding measure of taking refuge is to adopt self-rescuer or logical polybag of pressing wind to prior art for gas, but self-rescuer timeliness only 45 minutes can only be used for interim urgent emergency escape.The polybag of logical pressure wind need clad end user's whole health, and both shield people's sight line had limited all action again, and the people personnel's that take refuge safety also be cannot say for sure to demonstrate,prove.Reasonable equipment is the breather of band oxygen cylinder, and timeliness 4 hours can be used for the rescue personnel, and shortcoming is to cost an arm and a leg, and can not be equipped with in a large number.
Above-mentioned all equipments of saving oneself of taking refuge all can not solve the problem of aboveground, downhole communication contact, can not satisfy use lasting, convenient inexpensive requirement.If roadway stops up, can not get rid of for the moment, then wrecked personnel promptly break off the means of livelihood.
The objective of the invention is provides a kind of device that supplies down-hole collective gas to take refuge and give first aid to for the miner, relying on its wrecked personnel can safe for a long time breathing, diet and call for help contact to well head, and the closely first aid and carry out " closely screen and blow out " operation of double as down-hole.
This device filters pressure regulation air register (4) by at least two covers, at least one cover metal security seal cabin (9), and pressure meter (3), the total lock of air inducing (2), anti-release gate valve (1) is formed.Filter the voltage stabilizing that pressure regulation air register (4) is made up of filter regulator (6), purification air distribution bag (7) and the airline hose (10) etc. that are contained in the canister, purifier.Filter regulator (6) comprises branch airduct (13), control valve (14) and diaphragm type pressure regulation cleaner (15), and the cleaner end has a charcoal absorption cover.Press wind through a minute airduct (13) coarse filtration, through the centrifugation of pressure regulation cleaner, filter through charcoal absorption again, purify air distribution bag (7) intracavity bottom center an active carbon purifying jar (16) is arranged, press wind to enter in the jar through suction nozzle (17), airborne fine oil mist is adsorbed once more, delivers to gauze mask of the elastic positive pressure by the purified gas of distribution mouth (18) output through airline hose, and each purifies the partition bag can supply with 9 mouth mask purified gas at least.

Gas detector, carbon monoxide comparator, resuscitator, self-rescuer, phone, water fountain, steam vent (11) are housed in the security seal cabin and unload pressuring gasbag (12) etc.Enter the people in security seal cabin, can utilize gas or CO gas in the pressure wind dilution cabin of introducing, promptly seal with barotropic gas; isolated pernicious gas can take off spray mask behind assay approval, carry out normal activity; according to people's eupnea physiological requirement, less than 0.008kg/cm
2In case air pressure surpasses 0.04kg/cm
2, to unload pressuring gasbag (12) and promptly break, protection lung is injury-free, and gas is discharged through steam vent (11) in the cabin.
Advantage of the present invention is as follows:
Can for the long-time gas of many people take refuge and mine in during breaking out of fire, carbon monoxide is taken refuge.
2. can utilize the feed of security seal cabin, drinking-water, and can utilize phone to call for help, to obtain timely rescue to the well head contact.
3. can in time rescue these personnel that suffocate of down-hole invar, improve the personnel's that suffer a calamity or disaster " rate of surviving " and " rehabilitation rate ".
4. as the main security protection equipment of " closely shielding blow out ", shorten outstanding gaseous mine and blow out activity duration of operation, improve mine production work efficiency and increase economic benefit.
5. because this equipment can use for many people, consume and press air quantity few, lower, safe and reliable than disposable self-rescuer usage charges.
