For this problem, Chinese patent ZL200820136982.7 also discloses a kind of high-pressure compressed gas discharging device, this device comprises voltage-regulating system and heating system, described voltage-regulating system includes pressure governor, and pressure governor has input end and output terminal, it is characterized in that, described heating system is air temperature type heater, described air temperature type heater is made up of the pipeline installing endothermic plate, and the input end of pressure governor connects high pressure admission pipeline, and the output terminal of pressure governor is connected with air temperature type heater.
Program Problems existing does not have general applicability, reason is general in the south of China, its air temperature is general higher, so adopt air temperature type heater also can reach the object utilizing air temperature heat exchange as heating system, but due to ice box such as current north of Chinas, when winter, air temperature is extremely low, so air temperature cannot be utilized to exchange; So this region directly adopts steam type vaporizer usually, such design causes energy consumption larger.
Model utility content

As improvement, at least two cover voltage-regulating systems and heating system are composed in series multistagely unloads gas system, and namely high pressure admission pipeline first connects one-level pressure governor, then through heating system, connects second voltage regulation device and secondary heating system more afterwards.
As improvement, the pipeline connecting voltage-regulating system and heating system is provided with connection set, safety installations, measurement instrument, high pressure filter, thermometer and pressure meter, described connection set includes flange, ball valve, flow controller, and described safety installations contains safety valve, Emergeny Cutoff Valves, stop valve.
As improvement, the pipeline of connection one-level pressure governor input end is connected with flange, safety valve, ball valve, flow controller, Emergeny Cutoff Valves, filter and stop valve in turn to beginning.
As improvement, the endothermic plate of described sky temperature heater is the sheet metal that heat-conducting property is good, and endothermic plate disperses distribution centered by pipeline.
As improvement, the two ends of described pressure governor are also provided with bypass tube, bypass tube are connected with ball valve and flow controller.
As improvement, the pipeline connecting empty temperature heater after described pressure governor and pressure regulation is provided with the heating device preventing frozen block.
The utility model be to provide a kind of low-temperature region high-pressure compressed gas discharging device first by the pressurized gas of high pressure carrier vehicle through pressure device pressure regulation cooling after, enter into air temperature type heater again, gas flow pipeline after air temperature type heating absorbs atmospheric heat, temperature is made to increase, in low-temperature region, because temperature rises not obvious, so the gas after air temperature type heater heats through horizontal water-bath recuperator, gas after heating can flow to the second air temperature type heater in parallel with original air temperature type heater again, gas after second air temperature type heater heating is sent, secondary pressure regulation and heating can be carried out as required, although whole process adopts horizontal water-bath recuperator, but because the energy consumption of horizontal water-bath recuperator is lower, simultaneously through the gas of horizontal water-bath recuperator owing to having certain temperature, the icing phenomenon of air heater in low-temperature region can also be solved, thus low-temperature region can reach adopt compared with low energy consumption while high pressure compressed gas is unloaded, and ensure unloading efficiency.
