Abstract
A vehicle-mounted adhering natural gas steel cylinder with heat exchanger comprises a body of a steel cylinder with circular heads on two ends. The steel cylinder which is split-type with two parts connected through flanges and bolts is provided with a charging inlet, a discharging outlet and a pressure gauge. On one end of the steel cylinder is arranged a double-pipe heat exchanger which extends into the steel cylinder, wherein the central pipe of the heat exchanger is arranged as a circulating water inlet, while the casing pipe is arranged as a circulating water outlet, and the steel cylinder is evenly filled with super active carbon. The utility model has the advantages that: since the adhering natural gas steel cylinder belongs to a container of medium pressure, compared with a compressed natural gas cylinder, working pressure is reduce by 4/5 with material saved, weight reduced, cost reduced and safety improved; additionally, compared with a liquefied natural gas steel cylinder, the adhering natural gas steel cylinder does not need special cryogenic equipment, thereby not only greatly reducing cost, but also having remarkable environmental protection effect. The utility model provides an economical, safe and practical equipment for generalizing natural gas as automobile fuel.
Description
(1) technical field
The utility model relates to a kind of automobile natural gas steel cylinder, particularly a kind of automobile absorbed natural gas steel cylinder that has heat exchanger.
(2) background technology
At present both at home and abroad automobile mainly adopts following two kinds of forms with the mini gas steel cylinder: 1, steel bottle filled with compressed natural gas, soon natural fuels with the high pressure storage of 20MPa in steel cylinder; 2, liquefied natural gas steel cylinder is about to the oil field natural fuels as unstripped gas, makes the blue gas liquefy through freezing after desulfurization, dehydration, the purification to below-162 ℃ earlier, is filled in the special low temperature steel cylinder again.The shortcoming of steel bottle filled with compressed natural gas is, because the compression ratio height needs the superhigh pressure pressure container, so the cost height, and have potential safety hazard; The shortcoming of liquefied natural gas steel cylinder is that low-temperature storage need special cryogenic tank, so cost is also high.
(3) summary of the invention
The purpose of this utility model provides little, in light weight, economical and practical, the safe and reliable automobile of a kind of volume absorbed natural gas steel cylinder that has heat exchanger.
The technical solution of the utility model
A kind of automobile absorbed natural gas steel cylinder that has heat exchanger, it is characterized in that: the main body of absorbed natural gas steel cylinder is that two ends are the steel cylinder of circular head, steel cylinder is split type, its two parts are by the flange bolt together, steel cylinder is provided with inflation inlet, air extractor duct and compression indicator, and an end of steel cylinder is equipped with center tubular type heat exchanger and stretches in the bottle, and the base pipe of heat exchanger is made as circulating water intake, the sleeve pipe of heat exchanger is made as circulating water outlet, evenly loads super-activated carbon in the steel cylinder.
A kind of above-mentioned automobile is characterized in that: the material employing 34Mn2V of steel cylinder with the absorbed natural gas steel cylinder that has heat exchanger.
A kind of above-mentioned automobile absorbed natural gas steel cylinder that has heat exchanger, it is characterized in that: working pressure is 3.5MPa.
The utility model has the advantages that: absorbed natural gas steel cylinder belongs to medium pressure vessel, compares with steel bottle filled with compressed natural gas, and working pressure has reduced by 4/5, has saved material, has alleviated weight, has reduced cost, has improved safety.Compare with the liquefied natural gas steel cylinder, do not need special cyrogenic equipment, not only greatly reduce cost, and environmental-protection function is remarkable.The utility model provides a kind of economy, safe, practical equipment for promoting the use of natural fuels as motor vehicle fuel.
