Embodiment Construction

[0018] The preferred implementation of the device of the present invention will be described below with reference to the accompanying drawings.

[0019] attached figure 1 to attach Figure 5 In order to realize a specific non-electrically driven life support device of the present invention, the whole device includes three subsystems: an oxygen supply subsystem, a cooling and dehumidification control subsystem, and a carbon dioxide / carbon monoxide adsorption subsystem.

[0020] The oxygen supply subsystem such as figure 1 As shown, it mainly includes: a high-pressure oxygen cylinder 1, a pressure reducer 2, a low-pressure oxygen pressure gauge 9, a stop valve 10 and a flow meter 8, etc., and its connection mode is to rely on gas pipeline connection.

[0021] Cooling and dehumidification subsystems such as figure 2 As shown, it mainly includes: refrigerant storage bottle 18, stop valve 19, refrigerant inlet pipe 14, manual stop valve 13, capillary tube 12, evaporator 5, evap...

Abstract

The invention relates to a non-electric drive life support device, comprising three subsystems, namely an oxygen supply subsystem used for supplying oxygen, a carbon dioxide / carbon monoxide absorption subsystem used for purifying the air and a temperature reduction and dehumidification subsystem used for controlling temperature and humidity. The oxygen supply subsystem is connected with the temperature reduction and dehumidification subsystem by virtue of an oxygen pipeline, the carbon dioxide / carbon monoxide absorption subsystem is connected with the temperature reduction and dehumidification subsystem by virtue of a ventilation pipeline, and the temperature reduction and dehumidification subsystem utilizes kinetic energy of oxygen and kinetic energy of the purified air to enhance heat exchange. The system in the invention makes the best of reactive power of the oxygen supply subsystem and the carbon dioxide / carbon monoxide absorption subsystem to realize forced heat exchange of the temperature reduction and dehumidification subsystem, so that the system can normally operate without electric power supply; and the temperature reduction and dehumidification subsystem adopts a refrigerant storage bottle to substitute a compressor and a condenser, thus ensuring the system to operate normally under the condition of no electric power supply.

Description

technical field [0001] The invention relates to a life support device, which belongs to the field of refuge and lifesaving. Background technique [0002] At present, mineral mining is mainly concentrated underground. Due to the complexity of mine conditions, mine accidents cannot be completely avoided. The occurrence of mine accidents is generally sudden and short-lived, and it is difficult to send all underground personnel back to the ground safely in time. Therefore, developing underground refuge and life-saving equipment is an effective way to solve mine accidents and reduce casualties. [0003] Generally, when a mine accident occurs, it is necessary to provide a place for underground personnel to take refuge temporarily. Therefore, in addition to requiring the firmness of the refuge cabin, it is also necessary to provide the basic conditions for people to survive in the short term. These conditions include water supply, food supply, oxygen supply, cabin environment tem...
