Abstract
The present invention discloses a natural gas adsorbing storage tank and filling technology. A gas storage adsorbing agent is filled in the storage tank; a central circulating tube and an electric heating element are arranged in the storage tank; an adsorbing purifier and a cooler are arranged in a gas filling station. The problem of temperature rise of quick gas filling is solved by low temperature natural gas recirculation; high-temperature natural gas is used for the regeneration of the purifier. When necessary, inert gas blowing sweeping and evacuation or a temperature changing method is used for keeping the gas storing volume of the storage tank constant through the electric heating element and the central circulating tube in the storage tank.
Description
Technical field
The invention belongs to storage, transportation and the distribution technique of rock gas.
Background technique
China's natural gas (comprising casing-head gas, coal-seam gas) resource is not poor, but because of mainly containing in central and west regions, develops later.Though there is gas transmission line to build up in recent years,, not to finish in the short time aspect fund and engineering if build up the gas line network of broad covered area.Particularly the reserves of some source of the gas are limited, are unworthy building pneumatic tube.Therefore, the user is transported and distributes in the rock gas tinning use, still not present main path is even if also there is the very big market in the future.Secondly, for gas-fueled vehicles, absorbed natural gas storage tank replaces the high pressure compressed storage tank will cause the reduction of gas cost.
Existing canned rock gas adopts the high pressure compressed way.For increasing canned tolerance, must improve aeration pressure, common aeration pressure reaches 20-25MPa.For this reason, need possess the high pressure compressor of 6 grades of compressions, compressor investment, occupation of land and energy consumption have improved the aeration expense greatly.Simultaneously, the industrial grade of the storage tank of tolerance 20-25MPa pressure and deadweight also are quite serious problems.The situation of high pressure compressor or high pressure resistant storage tank also usually taking place to lack in the reality, have to reduce aeration pressure, causes the decline of canned capacity and the raising of cost of transportation.
Summary of the invention
The problems referred to above at present canned rock gas exists the object of the present invention is to provide a kind of absorbed natural gas storage tank and canning method, can be implemented in lower aeration pressure and are issued to bigger canned capacity.
The present invention includes natural gas storage tank and gas station aeration method two-part.The tank body available metal material of absorbed natural gas storage tank is made, and also can adopt nonmetallic material or composite material manufacturing, with weight reduction.Its structure characteristic is: tank body central authorities are provided with a gas circulating tube, and horn mouth is opened in the lower end of pipe, are surrounded by wire netting and filter cloth on mouthful.Fill high surface activity carbon or active carbon fibre fiber products in jar, sorbent is by screen cloth and filter cloth and other parts separation.In the sorbent of being filled, lay electric heating element.The pot-type equipment that aeration adopts mainly is made up of compressor, compressor outlet cooler, gas-liquid separator, purifier, recoler.It is characterized in that: the strong absorbed component in the rock gas is cleaned device and holds back; The heat of adsorption that produces during aeration is by at the short circle between storage tank and the recoler or comprising in the major cycle of purifier regeneration step and being shifted out; In major cycle, the higher gas of temperature is with one group in two groups of purifiers regeneration; Aeration pressure is 3-10MPa.
Below the present invention will be further described.The gas circulating tube of tank body central authorities provides gas circulation channel.During aeration, the rock gas that has removed strong absorbed component enters adsorbent bed from tank deck, and horn mouth enters Circulation pipe and returns at the bottom of the jar.Also can introduce regeneration gas (the higher gas of inert purge gas or temperature) or be connected by central circulating tube, make adsorbent reactivation with evacuation system.Electric heating element in the sorbent is used for improving adsorbent bed temperature when exitting fast, or is used for adsorbent reactivation where necessary.
Advantage of the present invention is: (1) is issued to the gas-storing capacity of high pressure compressed for the storage tank of same volume in the medium pressure level.Compare with slack tank, the natural gas tank loading amount increases multiple and depends on sorbent used specific surface area and filling density.(2) intermediate pressure compressor and medium pressure vessel have replaced high pressure compressor and high-pressure bottle.(3) overcome the heat of adsorption effect under quick aeration and the venting condition to the influence of canned capacity.(4) the canned capacity constant of assurance natural gas storage tank, the regeneration period of sorbent prolongs greatly.(5) under needs venting situation fast, also can reach necessary outgassing rate.

Embodiment
Embodiment: at volume is to fill a kind of high surface activity carbon in the gas holder of 100 liters (φ 360 * 1000).Under 5MPa aeration pressure, if do not fill sorbent, can only adorn 2.7 kilograms of rock gases, but if fill this kind active carbon, then canned capacity is brought up to 12.6 kilograms, be simple 4.7 times of compressing gas-storing capacity.If be scaled normal volume, the amount of natural gas of a gas holder release is about 16.5 cubic metres, for a three-person household, and approximately available one month.
Claims (2)
