This utility model provides a kind of BOG recycling device, as it is shown in figure 1, can be practiced as follows by improving；Including end sledge 1, thermometer A2, ball valve A3, Pressure gauge A4, electrical heating recuperator 5, ball valve B6, equipment importation 7, cryogenic globe valve 8, Pressure gauge B9, thermometer B10, low temperature check-valves 11, relief valve A12, Pressure gauge C13, gasifier 14, device for adding odor 15, exhaust stack outlet 16, equipment outlet 17, effusion meter 18, Pressure gauge D19, ball valve C20, relief valve B21, pressure regulator 22, ball valve D23, ball valve E24, ball valve F25；Equipment importation 7 end arranges cryogenic globe valve 8, low temperature check-valves 11, and connects gasifier 14；On the inlet end pipeline of logical gasifier 14, Pressure gauge C13 is set, the outlet conduit of logical gasifier 14 arranges Pressure gauge B9, thermometer 10 and relief valve A12；The outlet conduit of logical gasifier 14 is divided into two branch roads by threeway, and a branch road connects with electrical heating recuperator 5, and its communicating pipe arranges ball valve B6；Another branch road converges with the output channel of electrical heating recuperator 5, and this branch road arranges ball valve F25, and the output channel of electrical heating recuperator 5 arranges ball valve A3 and thermometer 2；The rear end pipeline of ball valve F25 collects with the output channel of electrical heating recuperator 5, and the pipeline after collecting is again split into two branch roads, and a branch road arranges ball valve E24, and another branch road arranges Pressure gauge A4, ball valve D23, relief valve B21 and Pressure gauge D19；Ball valve E24 connects with pressure regulator 22, mounting ball valve C20, effusion meter 18 on the output pipe of described pressure regulator 22, and effusion meter 18 is output as equipment outlet 17；Device for adding odor 15 accesses on the pipeline before equipment outlet 17.
LNG air supply system principle: the LNG liquid shipped from LNG low-temperature tanker；Enter LNG by fluid inlet pipe to unload sled；Then LNG low-temperature storage tank is entered by fluid inlet utilidor.Prize through LNG storage tank pressurization control from low-temperature storage tank LNG liquid out；Become gas after entering main gasifier gasification and enter pipeline；Smelly laggard access customer pipe network is added through pressure regulation, metering.The part boil-off gas (BOG) produced when LNG low-temperature tanker is unloaded, part boil-off gas (BOG) and LNG pipeline interior generation boil-off gas (BOG) that the LNG liquid stored in LNG low-temperature storage tank produces all reclaim sledge pipeline by BOG and enter gasifier, enter pressure regulation metering after being heated up by gasifier, recently enter user's pipe network.
BOG reclaims sledge and has little, the compact conformation of taking up room, easy to operate, low cost, easy to maintenance, and equipment can be moved for different places to use.
BOG reclaims sledge technological process and illustrates:
It is a kind of solution carrying out the BOG gas of storage tank or pipe section reclaiming that BOG reclaims sledge；BOG gas in storage tank or liquid are sent into reclaim and are become gas at normal temperature in sledge after gasifier gasification again after electrical heating recuperator re-heat and enter pipeline, through pressure regulation, measure, add smelly laggard access customer pipe network.
It is equipped with relief valve on pipeline on main pipe and after pressure regulation, it can be ensured that safety during supply after gasifier on sledge seat.
Gas pipeline section has electrostatic grounding cable to connect, and the frictional static of air-flow is led to ground electrode timely, prevents electrostatic accumulation from causing danger.
BOG carrys out gas and first passes through equipment importation 7 and enter gasifier 14 then in turn through cryogenic globe valve 8, low temperature check-valves 11, BOG gas absorbs heat in environment by gasifier 14 makes cryogenic gas become the gas close to ambient temperature, and usual gasifier 14 outlet temperature is not less than ambient temperature 10 DEG C.Again heat when gasifier exit temperature gas when subzero need to again pass by electrical heating recuperator 5 so that it is outlet temperature reaches above zero, if gasifier exit temperature is above zero, remove rear end pipeline without again adding hot gas through ball valve F25；Gas by after re-heat through ball valve E24 to pressure regulator 22, the gas pressure after re-heat is dropped to the pressure that client needs by pressure regulator 22, goes to use gas point through vent ball valve again after ball valve C20 is by effusion meter 18 metering.Pressure gauge C13 shows that inlet pressure, Pressure gauge B9 and thermometer B10 show that pressure and temperature after gasification, Pressure gauge A4 and thermometer A2 show pressure and temperature after gas re-heat, gas pressure after Pressure gauge D19 display pressure regulation respectively respectively；Relief valve A12 protection gasification rear line prevents pressure superelevation, relief valve B21 protection pressure regulation rear line from preventing pressure superelevation.Being provided with on pipeline before going out sledge mouth and add smelly point, smelly dose (Tetramethylene sulfide) is added pipeline and medium mixing by logical many attachment means 15.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this utility model.Multiple amendment to these embodiments will be apparent from for those skilled in the art, and generic principles defined herein can realize in the case of without departing from spirit or scope of the present utility model in other embodiments.Therefore, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
