Abstract

The utility model provides an LNG (liquefied natural gas) gasification station. The LNG gasification station comprises an unloading and pressurizing pry, a low-temperature storage tank, an air temperature gasifier group, a water bath type gasifier, a pressure-regulating and metering pry, a BOG (boil-off gas) heater, a BOG storage tank, an EAG (escape air gas) heater and a safety discharge device which are sequentially connected, wherein the BOG heater is respectively connected with the unloading and pressurizing pry, the low-temperature storage tank, the air temperature gasifier group, the water bath type gasifier, the BOG storage tank and the EAG heater, the EAG heater is connected with the safety discharge device, and the LNG gasification station is characterized in that a loop pipeline is arranged between the low-temperature storage tank and the air temperature gasifier group, and a regulating valve is arranged on the loop pipeline. The air temperature gasifier group has the double functions of gasification and pressurization by the storage tank and can reduce the leakage of LNG at the joint of the pipeline and further reduce the investment cost in a station area.

Description

A kind of LNG vaporizing station
Technical field
The utility model relates to the LNG applied technical field, relates in particular to a kind of LNG vaporizing station.
Background technique
Along with the scarcity of the mineral resources such as coal and oil, country is to improving constantly that energy-saving and emission-reduction require in addition, and rock gas is widely used in the every field such as industrial and civilian as a kind of emerging clean energy resource.Because the gas line network layout is limited, can not satisfy the demand of actual conditions far away, therefore, domestic many LNG storage and distribution station and the vaporizing station of having remedies breach on the demand.
The equipment of conventional LNG vaporizing station disposes: LNG unload supercharging sled, storage tank supercharging sled, low-temperature storage tank, empty temperature vaporizer group, water-bath type LNG vaporizer, BOG heater, EAG heater, pressure regulation metering sled, safety dumping system etc.Wherein the utilization ratio of storage tank supercharging sled is lower, and it and empty temperature vaporizer group are separated, and increased the self-evaporating equipment point of LNG, and the construction cost of whole vaporizing station are higher.
Summary of the invention
In order to address the above problem, the utility model provides a kind of LNG vaporizing station, comprise the supercharging sled of unloading, low-temperature storage tank, empty warm vaporizer group, water bath type gasifier, the pressure regulation metering sled, the BOG heater, the BOG storage tank, the EAG heater, safe discharge equipment, the described supercharging sled of unloading, low-temperature storage tank, empty warm vaporizer group, water bath type gasifier, the pressure regulation metering sled, the BOG heater, the BOG storage tank, the EAG heater, safe discharge equipment connects successively, described BOG heater is prized with the supercharging of unloading respectively, low-temperature storage tank, empty warm vaporizer group, water bath type gasifier, the BOG storage tank, the EAG heater connects, described EAG heater is connected with safe discharge equipment, it is characterized in that being provided with return between described low-temperature storage tank and empty temperature vaporizer group, described return is provided with modulating valve.
The beneficial effects of the utility model are: empty temperature vaporizer group has the dual functions of gasification and storage tank supercharging, has reduced the leakage of pipeline junction LNG, and has reduced station district cost of investment.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the connection diagram of the utility model low-temperature storage tank and empty temperature vaporizer group.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained, such as Fig. 1, Fig. 2,1-the unload empty warm vaporizer group of supercharging sled, 2-low-temperature storage tank, 3-water bath type gasifier, 4-pressure regulation metering sled, 5-BOG heater, 6-BOG storage tank, 7-EAG heater, 8-safe discharge equipment, 9-, 10-return, 11-modulating valve, 12-LNG tank car.
As shown in Figure 1 and Figure 2, LNG tank car 12, the supercharging of unloading sled 1, low-temperature storage tank 2, empty temperature vaporizer group 9, water bath type gasifier 3 and pressure regulation metering sled 4 connect successively, BOG heater 5 is connected with the supercharging sled 1 of unloading, low-temperature storage tank 2, empty temperature vaporizer group 9, water bath type gasifier 3, BOG storage tank, EAG heater 7 respectively, EAG heater 7 is connected with safe discharge equipment 8, between low-temperature storage tank and empty temperature vaporizer group, return 10 is set, modulating valve 11 is set on the return 10.
Embodiment:
LNG is transported to vaporizing station by LNG tank car 12, utilizes the supercharging sled 1 of unloading that LNG tank car 12 internal pressures are raise, and the LNG in the LNG tank car 12 is delivered to low-temperature storage tank 2 interior storages; Rise at the beginning, low-temperature storage tank 2 has pressure and empty temperature vaporizer group 9 does not have pressure, so LNG can successfully utilize low-temperature storage tank 2 pressure to flow into empty temperature vaporizer group 9, rising along with sky temperature vaporizer group 9 pressure, during with low-temperature storage tank 2 pressure balance, LNG in the low-temperature storage tank 2 then can not flow out outward, open the return 10 of low-temperature storage tank 2 and empty temperature vaporizer group 9 this moment, regulate pressure with balance low-temperature storage tank 2 according to the demand of outlet pressure by modulating valve 11, the pressure of low-temperature storage tank 2 is raise, by pressure difference the LNG in the low-temperature storage tank 2 is delivered to water bath type gasifier 3 through empty temperature vaporizer group 9, prize 4 pressure regulation through pressure regulation metering, metering, add and send into municipal gas ductwork after smelly; Enter the BOG storage tank stores after a self-evaporating rock gas part heats by BOG heater 5 in unload supercharging sled 1, low-temperature storage tank 2, empty temperature vaporizer group 9, water bath type gasifier 3 and reclaim, another part is discharged into the external world by safe discharge equipment 8 after BOG heater 5,7 heating of EAG heater.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
