Abstract
The utility model belongs to a civilian natural gas air feed gas storage device. The device can divide the gas storage pipe into a high-level pressure group, a medium-level pressure group and a low-level pressure group, unload the vehicle-mounted high-pressure natural gas storage device in a grading manner, balance the air pressure of each pipe after unloading, and supply gas to a user after pressure regulating treatment. The device has the advantages of high air storage pressure, large storage capacity, safety, reliability, small occupied area, underground arrangement, high unloading rate and relatively low cost of remote air supply, and is particularly suitable for supplying air to remote and small-area users.
Description
The utility model belongs to the caisson of civil natural gas supplying gas in small area.Particularly a kind of Xiang Xiang of can be used for, town resident pipe network provide the caisson of life with rock gas.This caisson especially is suitable for to life fuel gas is provided away from the township that sells gas company gas distributing system, town resident etc.
At present, the plenum system of town dweller's gas for domestic use generally is to transport to rock gas pressure regulation gas distribution station by gas production well site gathering station by gas pipeline, and then provides gas for domestic use by zone, cities and towns rock gas gas distributing network to each user.This kind plenum system does not have the advantages such as transport gas is safe and reliable, cost is lower that congealed for the big zone of population concentration, gas consumption, be a kind of natural gas transportation mode that generally adopts both at home and abroad at present yet.But for away from well site or the small towns or the outlying mountain area that sell gas company gas distributing system, because it is little that the user reaches gas consumption less, build separately that natural gas pipeline exists then that investment is big, unit gas transmission cost height, turnover be long, even disadvantage such as can not recoup capital outlay.And the gas holder that tradition adopts is as selling the spherical gas-holder that gas company is used to regulate peak period usefulness gas, (generally only 1.6Mpa) gas-storing capacity is little because volume is big, gas storage pressure is low, and be only applicable to the storage of supplying gas of conventional pipeline, and be unsuitable for adopting the on-board high-voltage natural gas transport to store; In addition, this type of spherical tank floor space is big, has defectives such as the construction work amount is big again if be located at sub level.
The purpose of this utility model is to design a kind of natural gas storage apparatus for supplying gas in small area at above-mentioned defective, with gram eye zonule remote line transportation gas cost height; And adopt spherical tank to have that volume is big, gas storage pressure is low, to disadvantages such as the relieving capacity (rate) of on-board high-voltage rock gas are low.Reach and reduce remote, zonule civil natural gas gas transmission, air feed cost, realize the purpose of the natural gasification of outlying small towns gas for domestic use; In addition, another purpose is to improve the hillman life to use fuel structure, to preserve the ecological environment.
Solution of the present utility model is to adopt the gas storage of pressure tube bundle, to reduce the caisson volume, to improve gas storage pressure and gas-storing capacity; Simultaneously gas storage tube bundle pressing force is divided into relative high, medium and low voltage triode group to on-board high-voltage rock gas storage relieving capacity improving the unloading rate and to reduce cost of transportation, thereby realize its purpose.Therefore the utility model storage apparatus for supplying gas comprises pressure air container and air inlet, pneumatic tube and control valve thereof provided thereon, drain pipe, blow-down pipe and control valve thereof; Key is that pressure air container of the present invention is the pressure tube bundle, this tube bundle comprises relatively high pressure, middle pressure and low pressure triode group and air inlet and connecting tube that Guan Zuyu high-pressure natural gas suction ports at different levels are communicated with, also is respectively equipped with control valve between this air inlet and connecting tube and pipe group at different levels; Then be communicated with between each gas storing pipe in pipe groups at different levels by connecting tube.In order effectively to regulate and the rock gas air pressure of control output, with gas storing pipe that is connected with pipe network and pipe network between also have additional control valve and 1～3 grade of pressure governor.And described gas storing pipe both can be steel pipe, also can adopt composite pipe; The safety of its work pressure forever is not less than 4.0Mpa for well.A whole set of caisson both can be located at ground, also can be embedded in underground, and with the latter for well.
The gas storage of pressure tube bundle has the gas storage pressure height to the utility model, reserves are big, floor space is little owing to adopting, and its device both can be located at ground, also can be embedded in undergroundly, and gas storage is safe and reliable; Adopt to divide the unloading of a high, medium and low voltage triode component level, it is strong to have relieving capacity again, to the unloading rate of on-board storage device up to 97% with first-class characteristics.Overcome background technique or carried the cost height, or the reservoir vessel volume is big, gas storage pressure is low, to disadvantage such as a little less than the relieving capacity of on-board high-voltage rock gas.
