Description
Technical field
The utility model relates to a kind of air-conditioning, is specifically related to the passive air-conditioning of a kind of carbon dioxide for mine rescue capsule.
Background technology
The China's coal-mine industry is being promoted lifesaving appliance at present, and require in 2013, all lifesaving appliance to be installed under all coal mine, wherein the colliery is the escape equipment of taking refuge under a kind of novel coal mine with the packaged type survival capsule (referred to as survival capsule) of escaping, it is positioned under the coal mine near the getting working face, when happening suddenly major accident under the coal mine, the down-hole distress personnel is escaped danger in emergency circumstances in immediately gug escape, can enter in the survival capsule fast and wait for rescue, to changing the mine disaster emergency management and rescue pattern of simple dependence external rescue, combined with external rescue to initiatively saving oneself by passive fallback, make the rescue work science, in order, effectively, and increase survival rate.Should possess the basic functions such as security protection, oxygen supply guarantee, air purification and temperature and humidity regulation, Environmental Monitoring, communication, illumination, power supply, personnel's living guarantee as the life saving survival capsule, specified guard time is not less than 96 hours.Wherein driven by power is not adopted in passive cabin, but adopts the compression arbon dioxide gas cylinder to promote blower fan, and it possesses independence, relies on self function under disaster environment fully, has solved an existence difficult problem, now widelys popularize.
Conventional refrigeration ventilation system all needs to have the driving of extrinsic motive can realize refrigeration usually, but in power electric or the whole situations of scattering and disappearing of electricity for subsequent use, some specific occasion or visual plant, the equipment such as facility, high-end electronic devices, instrument, hospital, weaponry of taking refuge such as coal mine still have refrigeration demand, guarantee its within a certain period of time can safe operation with close, at this moment under the environment that does not have extrinsic motive to drive, refrigeration just can't realize.In addition, in the explosive occasion of some easy alkene, then there is larger potential safety hazard in traditional refrigeration system hot line job.
Because the particularity of coal mine environment, down-hole ambient temperature is constant, CH
4, the concentration of toxic gases such as CO is higher, dust and humidity are higher, thus the outstanding behaviours of passive carbon dioxide air-conditioning aspect explosion-proof, energy-conservation so that this kind air-conditioning becomes a main direction of studying of survival capsule ring control equipment.But existing passive carbon dioxide air-conditioning mainly is to play refrigeration, and its function is more single, is unfavorable for lifesaving and environment optimization in the survival capsule.
The utility model content
The utility model will solve above-mentioned deficiency exactly, and a kind of passive carbon dioxide air-conditioning is provided, and reaches ventilating in the survival capsule, freeze and the multiple purpose that purifies air.
In order to reach above-mentioned effect, the utility model provides a kind of carbon dioxide for mine rescue capsule passive air-conditioning, comprise the carbon dioxide inlet, described inlet is communicated with the gas outlet by pressure reducer, evaporation and heat-exchange device, pneumatic fan and forms heat-exchange system, described evaporation and heat-exchange device comprises the evaporimeter of at least two parallel connections, the port of export of described evaporimeter is connected with the heat exchanger that confluxes, and the outlet side of the described heat exchanger that confluxes is connected with the inlet end of pneumatic fan, superheater respectively; Described pneumatic fan all is connected with described gas outlet with the outlet side of superheater.
The heat exchanger that confluxes in the utility model can be designed to the multi-channel parallel flowage structure according to the liquid evaporation specific volume variation of cold-producing medium, strengthens its heat transfer effect with this, and reduces the loss of flow process.
Described inlet is connected with pressure reducer by forecooler.Liquid CO 2 enters forecooler from carbon dioxide steel cylinder, again with the pressure reducer throttling after the cryogenic liquid heat exchange, the liquid of inlet is carried out precooling treatment, increase liquid specific gravity, reduce restriction loss.
In order to control the refrigerant liquid flow on the evaporimeter, the port of export of described evaporimeter is connected with flow valve and capillary tube in turn, and the described port of export capillaceous is connected with the air inlet end of the heat exchanger that confluxes.
