Background technique
The clean energy resource that with the rock gas is representative has at present obtained use more and more widely, and a kind of novel mode of movement that is different from the long-distance transport pipes gas transmission rises, and it is the conveying of carrying out rock gas with the low-temperature liquefaction mode.LNG Liquefied natural gas, english abbreviation are LNG (being Liquefied Natural Gas).Rock gas is the inflammable gas of in the gas field, exploiting out naturally, and main component is made up of methane.LNG is cooled to-162 ℃ and the LNG Liquefied natural gas that condenses into natural gas in gaseous state under normal pressure; Can practice thrift storage and transportation space and cost greatly after the natural gas liquefaction; And have characteristics such as calorific value is big, performance height; Therefore rock gas generally is to store with the LNG Liquefied natural gas form, and LNG is easy to obtain.Because of LNG can not be directly uses as the terminal using gases, LNG is prepared into the terminal using gases, need through the LNG gasification installation with its gasification after, and guarantee that the gas pressure after the gasification is stable, could satisfy requirement as the terminal using gases.Mainly adopt at existing LNG Liquefied natural gas air feed terminal is large-scale air feed terminal such as gas station; In addition; Be primarily aimed at gas consumption small liquid natural gas supply terminal little, that require with the natural gas transmission and distribution that gas point disperses, floor space is little in addition; A kind of storage pot type LNG Liquefied natural gas air feed terminal that is is arranged in the small liquid natural gas supply terminal; Advantages such as floor space is little owing to having, storage is sent conveniently at this small liquid natural gas supply terminal, it is easy to set up an office, pressure stability are used more widely, but this storage pot type LNG Liquefied natural gas air feed terminal also has following defective: Security and reliability are also undesirable.Combustion gas takes place to leak and can't find effectively in time; What often leaked when discovered very seriously or causes the consequence that can't save; This not only brings great hidden danger to safety; Also caused the cost allowance of combustion gas, and the manpower and materials of labor cause increasing of maintenance cost at aspects such as repairings.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes existing technology, and the storage pot type LNG Liquefied natural gas air feed that a kind of Security is good, reliability is high terminal is provided.
Realize that the above-mentioned purpose technological scheme is: a kind of storage pot type LNG Liquefied natural gas air feed terminal; Include unloading deck standard sledge, storage tank pressurization control sledge, liquified natural gas low-temperature storage tank and gasification pressure regulation measure control sledge; Unloading deck standard sledge is connected with storage tank pressurization control sledge; Storage tank pressurization control sledge is connected with gasification pressure regulation measure control sledge; Storage tank pressurization control sledge also is connected with the liquified natural gas low-temperature storage tank, and gasification pressure regulation measure control sledge includes vaporizer, heater, recuperator, pressure governor and flowmeter, and the intake line of unloading deck standard sledge is provided with liquid phase import and gas phase import; Pressure governor and flowmeter are arranged on the output pipe of gasification pressure regulation measure control sledge, also are provided with gaseous phase outlet on the output pipe.The utility model also includes device for adding odor, and device for adding odor is arranged on output pipe one side of gasification pressure regulation measure control sledge, and output pipe is provided with and adds smelly mouthful, device for adding odor with add smelly mouth and be connected.
Further, described vaporizer is an air-heating type gasifier.
Further, described recuperator is an explosion-proof type water-bath electric heater.
Further, described flow is counted turbine flowmeter or Roots type flowmeter.
After adopting technique scheme; Have a lot of benefits: (1) is because the utility model has increased device for adding odor; Device for adding odor can add a certain amount of tetrahydrothiophene odorants such as (THT) in combustion gas, dose the measure of odorant through adding device for adding odor, has guaranteed that combustion gas user and maintenance management personnel etc. can in time find, in time handle leakage accident with sense of smell; Thereby leakage accident is eliminated in bud, improved the equipment integral Security.Therefore the utility model Security is good, and reliability is high, and the utility model has but solved a difficult problem of existing technology with simple structure.(2) the utility model has also reduced the manpower and materials that are used in aspects such as repairing simultaneously owing to find to handle the loss of in time having avoided gas leakage to bring, and maintenance cost is reduced, and construction cost and operation cost are also lower.
