Description

A kind of new type mining isolation type chemical-oxygen self-rescuer

(1) technical field

Patent of the present invention relates to a kind of new type mining isolation type chemical-oxygen self-rescuer.

(2) background technology

According to the regulation of China's " safety regulations in coal mine ", the personnel gone into the well in every colliery should carry self-rescuer and go into the well, and when dangerous situation occurs in underground coal mine generation major accident, the personnel of going into the well should open and wear self-rescuer immediately and escape danger escape.Isolation type chemical-oxygen self-rescuer is the mining self-rescuer of one that each colliery of China more commonly uses, although this kind of self-rescuer exists more advantage, but there is also the shortcoming that need to improve a bit.Potassium superoxide oxygen generating agent in this kind of self-rescuer generate oxygen time need steam to participate in, and emergency escape personnel just worn this kind of self-rescuer escape danger escape time, do not breathe out steam, potassium superoxide also cannot generate oxygen staff breathing.For solving this problem, be just provided with in this kind of self-rescuer just wear self-rescuer escape danger escape time just can discharge the initial stage oxygen generator of a small amount of oxygen.Present initial stage oxygen generator has the three types such as sulfuric acid bottle, oxygen candle, little oxygen tank, but the initial stage oxygen generator of these three type all also exists the different shortcoming of degree and hidden danger, so that can not produce oxygen, wear self-rescuer escape of escaping danger for personnel and cause trouble, originally it was help device, instead become device of getting killed；For many years, each colliery of China all occurred this class to cause the example of casualties.Thus, research and develop novel initial stage oxygen generator or its substituted device makes the function of such mining self-rescuer more improve to become the research direction of related scientific research personnel.

(3) summary of the invention

The purpose of patent of the present invention is to there is more hidden danger for the existing three kinds of initial stage oxygen generators of solution, causing isolation type chemical-oxygen self-rescuer can not be the difficult problem of escape personnel's normal supply oxygen of escaping danger, provide a kind of hydrophilic catalyst catalytic convention design substituting three kinds of initial stage oxygen generators, thus be born and the mining isolation type chemical-oxygen self-rescuer of latest generation.

Patent of the present invention is achieved through the following technical solutions:

A kind of new type mining isolation type chemical-oxygen self-rescuer; it is under the existing mining immovable premise of isolation type chemical-oxygen self-rescuer basic structure; instead of existing three kinds of initial stage oxygen generators with a kind of hydrophilic catalyst catalytic convention design, escaping danger the when that escape personnel just having worn use self-rescuer for underground coal mine supplies a certain amount of air playing respiratory protection effect.The feature of hydrophilic catalyst catalytic convention design is: a container equipped with hydrophilic catalyst, also being respectively provided with screen layer at the two ends of container, the outlet side of container is connected with the inside of self-rescuer oxygen generator, and the inlet end of container is real with stopper plug, if opening stopper, stopper just leads to air.

Described catalyst, it can change into nontoxic carbon dioxide carbon monoxide poisonous in air；Described hydrophilic catalyst is the new catalyst that domestic and international market the most just occurs, it is not afraid of the invasion of steam, has had the intervention of certain steam, and it is to the changing effect of carbon monoxide better；And catalyst before this, can be described as again " hydrophobicity catalyst ", after this kind of catalyst runs into the invasion of steam, catalyzed conversion effect can gradually reduce or even thoroughly lost efficacy.

Described container, it is the carrier of hydrophilic catalyst, stopper, screen layer, stay cord, after assembling screen layer, hydrophilic catalyst, stopper, stay cord, is generically and collectively referred to as hydrophilic catalyst catalytic convention design.

The screen layer at described container two ends, arranges the purpose of screen layer, is for preventing from leaking outside hydrophilic catalyst.

Described stopper, when new type mining isolation type chemical-oxygen self-rescuer product is in factory-assembled, just blocks the container filling hydrophilic catalyst tight；Only escape danger escape when coal mine down-hole personnel is in danger, when opening and wear self-rescuer, open stopper immediately, first the outside air after breathing by hydrophilic catalyst catalyzed conversion, now the carbon monoxide in outside air is become carbon dioxide to health fanout free region by hydrophilic catalyst catalyzed conversion the most substantially, after personnel have breathed several mouthfuls of these air, the most just have and enter into oxygen generator from the steam breathed out in the mouth, potassium superoxide oxygen generating agent in oxygen generator also will generate pure oxygen after touching steam therewith, when finding should immediately stopper be blocked up again after air bag is full of by gas the inlet end of tight container.

Described hydrophilic catalytic convention design and stopper, also an important effect, after air bag is deflated, shows that the potassium superoxide oxygen generating agent in oxygen generator is exhausted the most substantially, the most also can open stopper, and support personnel's eupnea is successfully escaped danger escape.

Described stay cord, one end is fixed on container, and one end is fixed on stopper, it is to avoid in use stopper is lost.

The invention has the beneficial effects as follows: in the present invention, existing initial stage oxygen generator is instead of with hydrophilic catalytic convention design, overcome and solve the potential safety hazard that existing initial stage oxygen generator there may exist, thus provide the mining isolation type chemical-oxygen self-rescuer of latest generation, make the isolation type chemical-oxygen self-rescuer manufacturing technology of China reach international most advanced level.

(5) detailed description of the invention

As shown in Figure 3 first screen layer is put into container bottom near air outlet, i.e. fill in container into enough hydrophilic catalyst, after placing second screen layer in container, the stopper of bolt jail stay cord is stoppered the inlet end of container, just constitute hydrophilic catalyst catalytic convention design.

When assembling isolation type self-rescuer product in factory, the outlet side of hydrophilic catalyst catalytic convention design as parts is completely embedded with the air inlet of oxygen generator, and other assembly technology is completely the same with the assembly technology of existing isolation type chemical-oxygen self-rescuer.

When underground coal mine generation major accident, the escape personnel of escaping danger in danger wears and uses novel and wear and uses the method for existing mining isolation type chemical-oxygen self-rescuer the most basically identical, only wears the method for use new type mining isolation type chemical-oxygen self-rescuer simpler and more direct and save survival time of tens seconds；Personnel escape danger escape time, open lower casing and pull up stopper, so that it may wear use immediately, be drawn into the air being fallen carbon monoxide by hydrophilic catalyst catalyzed conversion, the carbon dioxide in the air of exhalation is transformed into oxygen by potassium superoxide oxygen generating agent again.And if existing isolation type chemical-oxygen self-rescuer, personnel escape danger escape time, just can wear use when waiting the gas having about 2 liters for about 20 seconds in air bag after obtaining initial start stage oxygen generator after opening lower casing, in this time of about 20 seconds, personnel drink into how many toxic and harmfuls.
