Abstract
The utility model discloses a BOG retrieves liquefaction LNG system device, return the storage tank including BOG from tank wagon, cryogenic compressor, liquefaction cold box, buffer tank, cooler, compressor and LNG. The utility model discloses with cryogenic compressor and cryocooler perfect adaptation, satisfy the technological requirement, the refrigeration is fast, practice has proved that 1.5h just can accomplish refrigeration - 150 DEG C, and the energy consumption is low, and the liquefaction energy consumption is less than 0.8KWhNm3, and the direct storage tank that returns of LNG that the refrigeration obtained need not to increase the storage tank, can not thoroughly solve BOG and retrieve into pipe network, and the recycle problem of CNG inconvenience is failed outward to the high -pressure storage tank of on -the -spot nos CNG.
Description
Technical field
The utility model relates to a kind of retracting device, particularly relates to a kind of BOG and reclaims liquefaction LNG system and device.
Background technology
Due to LNG(liquefied natural gas) Vehicle Fueling Station and LNG carrier, technique restriction and operation characteristic, make to there is BOG(boil-off gas in LNG station field and LNG carrier operation process) irretrievable problem, both affected the economy of LNG station field and the operation of LNG carrier, also environment had been affected.
Utility model content
The purpose of this utility model is just to provide a kind of BOG to reclaim liquefaction LNG system and device to solve the problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises BOG from tank car, cryogenic compressor, liquefaction ice chest, surge tank, cooler, refrigeration compressor and LNG return storage tank, described BOG is connected with the inlet end of described cryogenic compressor from the gas output end of tank car, the outlet side of described cryogenic compressor is connected with the first inlet end of described liquefaction ice chest, connect after described refrigerator and be connected with the inlet end of described refrigeration compressor in first outlet side of described liquefaction ice chest, the outlet side of described refrigeration compressor is connected with the inlet end of described surge tank, the outlet side of described surge tank is connected with the second inlet end of described liquefaction ice chest, second outlet side of described liquefaction ice chest is returned storage tank with described LNG and is connected.
The utility model is preferred, described cryogenic compressor is connected with the first motor.
The utility model is preferred, described refrigeration compressor is connected with the second motor.
The utility model is preferred, and the first inlet end of described liquefaction ice chest and the first outlet side are arranged at the upper end of described liquefaction ice chest, and the second inlet end of described liquefaction ice chest and the second outlet side are arranged at the lower end of described liquefaction ice chest.
The utility model is preferred, and inlet end and the outlet side of described surge tank are provided with switch, and the inlet end that described LNG returns storage tank is provided with ball valve.
The beneficial effects of the utility model are:
The utility model is by cryogenic compressor and Cryo Refrigerator perfect adaptation, meet technological requirement, refrigeration is fast, and facts have proved that 1.5h just can complete refrigeration-150 DEG C, energy consumption is low, liquefaction energy consumption is less than 0.8KWh/Nm3, the LNG that obtains of freezing directly returns storage tank, without the need to increasing storage tank, thoroughly solving BOG and reclaiming into not pipe network, on-the-spot without CNG high pressure storage tank, the recycling problem of outer defeated CNG inconvenience.
