Embodiment Construction

[0015] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0016] 1. Preparation of chemical regeneration pills:

[0017] Weigh 18kg of potassium superoxide powder, 0.4kg of diatomaceous earth, 0.8kg of calcium peroxide, and 0.8kg of calcium hydroxide, and dry at 110°C for 12 hours in a nitrogen environment, mix them evenly in proportion, and put them into a tablet machine for tableting, then crush and sieve The medicine particles with a particle size of 3-7 mm were selected by sorting.

[0018] 2. Preparation of air regeneration medicine board:

[0019] Put the above-mentioned chemically regenerated drug granules into the net clips, each net clip is filled with 1 kg of granules, and the upper opening is closed. Packed medicine boards are put into iron boxes and sealed for storage.

[0020] 3. The use of air regeneration system:

[0021] When in use, according to the nu...

Abstract

The invention discloses an air regeneration system for coal mine emergency refuge, belonging to the technical field of coal mine danger removal lifesaving. The system is characterized by being composed of an air regeneration drug plate and an air regeneration device, wherein the air regeneration drug plate consists of a net clip and chemical regeneration drug particles; the chemical regeneration drug particles are put into the net clip; the net clip is a flat cuboid consisting of a metal wire net and angle iron; the air regeneration device is made from a stainless steel plate, and a cover is arranged at the top and bottom respectively; a fixing frame is arranged at the middle part of the cover; convection holes are formed on the two sides of the box body; two layers of support frames made from steel wires are arranged in the air regeneration device; and 14 air regeneration drug plates can be mounted on each layer. The chemical regeneration drug particle is prepared from 75-90% of potassium hyperoxide, 2-5% of kieselguhr, 4-10% of calcium peroxide and 4-10% of calcium hydroxide by the following steps of: uniformly mixing the components according to the proportion; tabletting the mixture in a tablet press; crushing; and screening and selecting drug particles with particle sizes of 3-7mm. Through the invention, the shortcomings of the traditional potassium hyperoxide oxygen supply system are overcome, the oxygen release speed of the drug is steady, and the reaction product is easy to dispose.

Description

technical field [0001] The invention belongs to the technical field of coal mine emergency rescue and rescue, and relates to an air regeneration system for coal mine emergency avoidance. Background technique [0002] According to the surveys of mine accidents in various countries in the world, the miners who were injured and died instantly at the scene of fire, explosion and other accidents only accounted for a part of the casualties in the accident. Fleeing from the scene of high-temperature, toxic and harmful accidents, resulting in death by drowning, poisoning or suffocation. Therefore, all countries are vigorously building mine refuge chambers and mine rescue cabins, so as to provide a safe confined space for miners who cannot evacuate in time after a mine accident, thereby winning a longer survival time and waiting for outside rescue. Once the refuge chamber or rescue chamber is activated, in order to ensure the safety of personnel, the life support system in the chamb...
