Description

A kind of Self-rescuer

Technical field:

The utility model relates to a kind of Self-rescuer, relates in particular to a kind of self-rescuer for colliery.

Background technology:

In mine construction and production process, because natural environment is complicated, operating environment is poor, in addition many shop floor workers are comprehensive not enough to mine disaster objective law understanding, busy off one's guard and cause operating against regulations or giving directions against regulations, greatly may cause some burst accidents, in order effectively to process the burst accident of mine, protection worker life security, reduce national wealth loss, must be according to two large < < rules > > (safetys regulations in coal mine, colliery rescue rules) requirement, carry out rescue.Also will educate worker is actively saving oneself and is calling for help simultaneously.

Mine self-rescuer is that a kind of volume is little, carrying portable, but action time the short respiratory protection instrument for miner individual.Main application is while having an accident under coal mine, and miner wears its disaster area that can speed away from be full of the roadway of toxic and harmful.Therefore, < < rules > > regulation: " enter well personnel and must carry self-rescuer ".

The mine self-rescuer of domestic main use at present has AZL-60 type filter type self-rescuer and AZH-40 type chemical oxygen self-rescuer, and these two kinds of self-rescuers are disposable products and had both been unfavorable for protection of the environment, have also greatly wasted relevant resource.The self-rescuer principle of the utility model design is by the appropriate design of self-rescuer structure and the suitable reactive material of employing, becomes recycling mine self-rescuer.Meanwhile, this self-rescuer also can be widely used in the escape of the poison gas leakage accidents such as oil, chemical industry and laboratory.

Utility model content:

Problem to be solved in the utility model is to provide a kind of self-rescuer that can repeatedly utilize.

The technical scheme that the utility model adopts is: this self-rescuer is by shell, breathing equipment, cooling agent, reative cell, water storage room, CO ₂other structures such as molecular sieve form, and the main chemical reactions of the utility model self-rescuer inside is as follows:

2Na ₂O ₂+2H ₂O＝4NaOH+O ₂(1)

2Na ₂O ₂+2CO ₂＝2NaCO ₂+O ₂(2)

Reaction (1) is for starting reaction, and this exothermic heat of reaction reaction, emits heat 452.6kJ/mol, and reaction (2) does not react at normal temperatures, and reaction condition is heating.Under the effect of reaction (1) liberated heat, reaction (2) just can be carried out.According to the design feature of device, by chamber designs, be Dismountable, can be again by Na after the reactant in self-rescuer uses ₂o ₂and CO ₂pack reative cell into, again utilize.The utility model self-rescuer belongs to chemical oxygen self-rescuer, adopts Na ₂o ₂with H ₂o and CO ₂reaction produces oxygen, the CO in reative cell ₂after having reacted, the CO of characteristics of contaminated respiratory droplets ₂can supplement in time, until the Na in self-rescuer ₂o ₂exhaust completely.

The breathing equipment of this self-rescuer is comprised of mouth mask, breathing catheter, outlet valve, inlet valve, non-return valve, expiration conduit, and wherein outlet valve and inlet valve are being controlled respectively expiration and air-breathing; The effect of non-return valve is when to be that the gas pressure in self-rescuer is excessive cause having difficulty in breathing, and inner gas can break through non-return valve and flow in extraneous air, and due to the effect of non-return valve, extraneous air cannot enter along non-return valve the inside of self-rescuer simultaneously; Expiration conduit lower end is inserted into the bottom of reative cell, and object is the CO that makes characteristics of contaminated respiratory droplets ₂can with Na ₂o ₂react fully.

The reative cell of this self-rescuer is comprised of three parts, is respectively Na ₂o ₂storage chamber, CO ₂storage chamber, water storage room, its Na at the middle and upper levels ₂o ₂storage chamber and the CO of lower floor ₂storage chamber is separated by pore iron net, and object is to guarantee Na ₂o ₂can not drop to CO ₂in storage chamber, and CO ₂can enter Na ₂o ₂in storage chamber.Water storage room is arranged in Na ₂o ₂one side of storage chamber.When starting switch, Shui Huicong water storage room flows into Na ₂o ₂in storage chamber, reaction (1) just starts to react, and emits a large amount of heat simultaneously, for reaction (2) provides reaction condition, reaction (1) with react (2) and all can emit a large amount of oxygen.

The cooling agent of this self-rescuer is arranged in the upper end of reative cell, and both are separated by pore iron net, and cooling agent is mainly used in the oxygen that cooling reaction produces, and prevents that excess Temperature from causing breathing to be obstructed.One deck CO is arranged in cooling agent upper end ₂molecular sieve, object is to stop most CO ₂enter O ₂apotheca in, in breathing catheter lower end, arrange again one deck CO simultaneously ₂absorbent, object is the CO of the air-breathing middle remnants of absorption ₂.

Advantage and the good effect that the utlity model has are: a kind of Self-rescuer of the utility model can play the inherently safe of protection coal miner, has also greatly saved relevant resource.By to the appropriate design of self-rescuer structure and the suitable reactive material of employing, become recycling self-rescuer.

Accompanying drawing explanation:

Fig. 1 is a kind of structure diagram of Self-rescuer.

Wherein: 1-mouth mask, 2-breathe deferent, 3-CO ₂absorbent, 4-outlet valve, 5-inlet valve, 6-blast pipe, 7-non-return valve, 8-air bag, 9-O ₂apotheca, 10-expiration conduit, 11-shell, 12-CO ₂molecular sieve, 13-Na ₂o ₂storage chamber, 14-pore iron net, 15-cooling agent, 16-water storage room, 17-water-supply-pipe, 18-valve, 19-switch, 20-thermal insulation layer.

The specific embodiment:

Below in conjunction with accompanying drawing and specific embodiment, the utility model is elaborated.

As shown in Figure 1, a kind of Self-rescuer described in the utility model comprises breathing equipment (mouth mask 1, breathing catheter 2, outlet valve 3, inlet valve 4, non-return valve 5, expiration conduit 10), reative cell (Na ₂o ₂storage chamber 13, CO ₂storage chamber 12, water storage room 16), other parts such as cooling agent 15, thermal insulation layer 20, shell 11.When starting switch 19, the water of water storage room 16 can flow into Na ₂o ₂in storage chamber 13, reaction (1) just starts to react, and emits O simultaneously ₂with a large amount of heat, reaction (1) liberated heat, for reaction (2) provides reaction condition, when reaction (2) reaction, will consume CO ₂cO in storage chamber 12 ₂, and produce a large amount of oxygen, the CO in reative cell ₂after having reacted, the CO of characteristics of contaminated respiratory droplets ₂can supplement in time, until the Na in self-rescuer ₂o ₂exhaust completely.The O that reative cell produces ₂with the CO in reative cell ₂can pass through Na ₂o ₂the pore iron net 14 of storage chamber 13 upper ends flows in cooling agent 15, owing to having arranged one deck CO in cooling agent 15 upper ends ₂molecular sieve 12, can stop most CO ₂enter O ₂in apotheca 9, in breathing catheter 2 lower ends, arrange one deck CO again simultaneously ₂absorbent 3, object is the CO of the air-breathing middle remnants of absorption ₂, this just can guarantee the CO in incoming call human body ₂within the scope of safe concentration.According to the design feature of device, by chamber designs, be Dismountable simultaneously, can be again by Na after the reactant in self-rescuer uses ₂o ₂and CO ₂pack reative cell into, again utilize.
