Description
Technical field
A kind of commercial plant is the utility model is related to, storage tank charging device is more particularly to pressed in one kind.
Background technology
Existing low-temperature liquid filling system is broadly divided into two kinds, and the first critical piece is normal pressure or low pressure, low temperature liquid storage
Tank and filling equipment.Its cardinal principle is to be higher than tank car using cryogenic liquid storage tank hydrostatic level, after groove interior pressure is let out to the greatest extent again
Cryogenic liquid in storage tank is dispensed to each cryogenic liquid by pipeline and transported in tank car, when filling every time, due to cryogenic liquid
Cryogenic liquid vaporizer can be caused with external world's heat exchange, groove interior pressure can rise, and must be thus vented to vaporizing this part
Processing, cause the significant wastage of gas.If handled without emptying, groove interior pressure stores up pot liquid after rising can not
Tank car is filled with, filling to complete.And small due to filling pressure difference, filling the time can be very long, extremely inefficient, second of main portion
Part is normal pressure or low pressure, low temperature liquid storage tank, liquid pump and filling equipment.Its cardinal principle is pressurizeed using liquid pump, then is passed through
Cryogenic liquid is dispensed to each cryogenic liquid and transported in tank car by pipeline.When filling every time, because precooling cryogenic liquid pump can be led
Cryogenic liquid vaporizer emptying is caused, so results in the significant wastage of gas, if handled without emptying, low temperature after temperature rise
Liquid will be vaporized, and volume drastically expands, and the gas after vaporization can cause tank inner pressure after entering normal pressure or low pressure storage tank
It can drastically raise, trigger security incident.Electric energy will be consumed by filling car operation cryogenic liquid pump every time simultaneously, cryogenic liquid pump buying,
Maintenance cost is also higher.
For above two because pressure of storage tank is low, the cryogenic liquid stored in storage tank can cause pressure rise due to vaporizing,
More than storage tank design pressure when must be vented processing, otherwise will trigger security incident, thus itself waste it is also larger.Therefore,
It is proposed that storage tank charging device is pressed in one kind.
Utility model content
Main purpose of the present utility model is pressing storage tank charging device in one kind is provided, and can effectively solve background technology
The problem of middle.
To achieve the above object, the technical scheme that the utility model is taken is:
Storage tank charging device, including low pressure, low temperature liquid storage tank, middle pressure is pressed cryogenic liquid storage tank, booster and to fill in one kind
Install standby, gas withdrawal line is provided with the upper side of the low pressure, low temperature liquid storage tank, under the low pressure, low temperature liquid storage tank
Square side is provided with communicating pipe, and described communicating pipe one end is connected with middle pressure cryogenic liquid storage tank, medium pressure cryogenic liquid storage tank
Upside is provided with efferent duct, is provided with input pipe on the downside of medium pressure cryogenic liquid storage tank, the input pipe and efferent duct are another
End is connected with filling equipment, and the filling equipment side is connected with booster, and the input pipe is internally provided with inlet valve, described
Communicating pipe is internally provided with communicating valve.
Further, opposite side is provided with feed tube above the low pressure, low temperature liquid storage tank.
Further, described gas withdrawal line one end is connected on the pipeline of air separation plant, and the other end is connected to middle pressure
In cryogenic liquid storage tank.
Further, the gas withdrawal line is internally provided with recovery valve.
Further, the efferent duct is internally provided with outlet valve.
Compared with prior art, the utility model has the advantages that:Storage tank charging device is pressed in this kind:
1. the utility model is simple in construction, when filling cryogenic liquid, it is only necessary to open booster and fill tank inner pressure increasing certainly
Pressure needed for dress, filling process is without other equipment without other energy resource consumptions., can be effective after storage pot liquid all fills
Remaining gas in storage tank is reclaimed, so as to reduce gas discharge, protects environment;The waste after filling is reduced, is increased the benefit.
2. preventing the air accumulation of emptying, potential safety hazard is caused.Simultaneously because inherently need to be pressurized when filling, low temperature
Pressure caused by vaporization, which rises, during fluid storage can not have to emptying, further reduce gas discharge.
3. among pressure cryogenic liquid storage tank in all liq filled or needed the when of falling liquid, open recovery valve, in force down temperature
Gas component enters air separation unit liquefaction and stored to enter low pressure storage tank after liquid in wet tank, when pressure recovery to normal pressure
Recovery valve is closed, opens communicating valve, again liquid.So recycle, both reached the purpose that the not outer row of product wastes, and realized again
Car is rapidly and efficiently filled after supercharging, while whole process does not produce extra energy resource consumption.
