From larger, floor space is big, high cost for the equipment mutual spacing such as machine, immersed pump, and in-site installation is complicated, makes the duration longer.
Current box skid station haves the shortcomings that following：Accumulator tank and low temperature immersed pump are all disposed within base, unfavorable
In the liquid that goes out of low temperature immersed pump, inefficiency.
Utility model content
The purpose of this utility model is exactly to provide a kind of LNG box skid station.
To achieve these goals, the utility model adopts the following technical scheme that：
A kind of box skid station of LNG, including LNG storage tank, storage tank erection support, warning device, booster, low temperature is dived liquid
Pump, liquid filler, PLC explosion proof control case, instrument wind, safety vent device, described LNG storage tank is fixed on by storage tank erection support
On base, low temperature immersed pump, booster and EAG heater assembly, PLC explosion proof control case, instrument wind are fixed on base, institute
State LNG storage tank, low temperature immersed pump, liquid filler, be sequentially connected by pipeline；During liquid feeding, LNG enters low temperature from LNG storage tank liquid outlet
Immersed pump, enters liquid filler after low temperature immersed pump pressurizes and finally enters in LNG bottle, and during storage tank supercharging, LNG is from LNG storage tank
Liquid outlet returns storage tank by LNG storage tank gas phase mouth after entering booster and EAG heater assembly gasification pressurization, improves
The pressure of storage tank itself, described safety vent device includes spark arrester and exhaust stack, and spark arrester is arranged on exhaust stack exit,
Described booster and EAG heater assembly are positioned over tank bottom.
The level sensing of described LNG storage tank adopts differential pressure type liquid level meter.
Arrange in described framework in more than one combustion gas probe apparatus, described framework and more than one infrared alarm dress is set
Put.
The beneficial effects of the utility model：
LNG storage tank of the present utility model is fixed on base by erection support, increased storage tank and low temperature immersed pump
Liquid level is poor, and be conducive to low temperature immersed pump goes out liquid, improves operating efficiency, and booster and EAG heater are put by this equipment
It is placed in tank bottom, save installing space, the construction work such as cofferdam that common skid station needs are undertaken by this equipment by owner
Be integrated in equipment, reduced the construction cost of owner, be suitable for resettlement, or quickly build a station layout seize market use.
The level sensing of this equipment storage tank adopts differential pressure type liquid level meter, can monitor the height of liquid level in storage tank in real time, prevents
Only liquid level is too high, and liquid overflows, and keeps certain liquid level, timely topping up.The built-in multiple combustion gas probe apparatus of this equipment, infrared
Warning device, when there is gas leakage, can automatically send alarm signal, being conducive to the safe operation of device.
The utility model passes through rational deployment, and equipment is combined into one formula, shortens pipeline, so that LNG is flow through in pipeline
When, decrease the heat absorbing from environment, thus decreasing the generation of BOG gas and saving media flow distance, more increase
Effect；Due to the shortening of pipeline, reduce the cost of pipeline cold insulation；
This equipment is understood some EAG gas and is produced, and the EAG gas of generation collects through pipeline, enters EAG heater,
Improve EAG temperature to more than -107 DEG C, be vented through blow-down pipe by spark arrester.
Booster, EAG heater, low temperature immersed pump, filling machine, PLC explosion proof control case etc. are arranged in base by this equipment
On, eliminate the making of installation foundation.
Whole equipment is highly integrated, and Pipe installing, apart from short, decreases heat retaining operation.
Only flange need to be connected during installation, decrease mounting material and human input, cost-effective, shorten installation work-hour.
