Embodiment 1

[0017] Example 1:

[0018] A gas scrubbing system for an underground shelter, which consists of: a compressed air bottle 1, the compressed air bottle is connected to a pressure reducing valve 2, and the pressure reducing valve is connected to an air duct 4 through a pipeline 3, the The air duct is connected to the pneumatic blower 5 through pipelines, the pneumatic blower has a muffler 6 and a regeneration air outlet, the inlet of the pneumatic blower is equipped with a filter screen 7, and an adsorbent 8 is installed above the filter screen .

[0019] In the gas scrubbing system for underground shelters, the air blower 5 , the muffler 6 , the filter screen 7 , and the adsorbent 8 are all installed in an air box 9 .

Embodiment 2

[0021] According to the gas scrubbing system for underground shelters described in Embodiment 1, the pressure reducing valve includes a high pressure gauge 10 and a low pressure gauge 11 .

Embodiment 3

[0023] A method of using the product of Embodiment 1-2 to carry out gas washing in an underground refuge, wherein the oxygen in the compressed air bottle is decompressed by a pressure reducer, and the speed of the pneumatic fan is controlled by adjusting the gas processed by the pressure relief valve; The treated air enters the air box and passes through the adsorbent and filter to remove the harmful gas in the mixed air and filter out the dust, then enters the pneumatic fan, merges with oxygen, and the oxygen-dissolved gas is output with the rotation of the fan.

[0024] When the refugee personnel mine accident took place, the people first opened the underground refuge door and entered the transition cabin, and closed the cabin door. Open the control valve of the gas scrubbing unit in the transition chamber to wash the gas in the transition chamber for 3 to 5 minutes, close the control valve of the gas scrubbing unit in the transition chamber, and start it again when it is nec...

Abstract

The invention relates to a gas washing system and washing method for an underground shelter. The domestic traditional gas washing systems for underground shelters need electric drive, if mine disaster occurs, no power is provided under the general conditions, so that the gas washing systems for underground shelters lose action, and the rescue purpose can not be achieved, thereby bringing potential safety hazards for rescue works. The gas washing system for an underground shelter comprises a compressed air bottle (1), wherein the compressed air bottle is connected with a pressure reducing valve (2); the pressure reducing valve is connected with an air channel (4) through a pipeline (3); the air channel is connected with a pneumatic blower (5) through a pipeline; the pneumatic blower is provided with a silencer (6) and a regenerated air outlet; a filter screen (7) is arranged at the inlet of the pneumatic blower; and an adsorbing agent (8) is arranged above the filter screen. The invention is used for air purification and regeneration in the underground sheltering process.

Description

Technical field: [0001] The invention relates to a gas washing system and a washing method for an underground shelter, in particular to a gas washing system for an underground shelter and a washing method using the system. Background technique: [0002] The gas scrubbing systems used for underground shelters on the existing domestic underground shelters all need to be driven by electricity. If there is no electricity in general when a mine accident occurs, the gas scrubbing system used for underground shelters on the underground shelters The system has just lost its function, and the purpose of rescue cannot be achieved; it has brought potential safety hazards to the rescue work. Invention content: [0003] The purpose of the present invention is to provide an air filter system, which is suitable for the transition cabin of the underground shelter, to remove the harmful gas and dust brought in by the refugees when they enter the transition cabin, so as to ensure their life...
