Abstract
The utility model discloses a low temp. LPG storage tank which can recycle low temp. gasification gas. A cooling recovery container of gasification gas (10) is arranged in an inner storage tank (2). A recovery LPG storage tank (15) is arranged at the lower part of the inner storage tank (2). An upper communicating pipe (5) and a lower communicating pipe (11) are arranged on the cooling recovery container of gasification gas (10). A drain tube is arranged on the recovery LPG storage tank. The utility model can recycle the low temp. gasification gas in the tank into low liquefied gas to re-use, and avoid the loss of emptying of gasification gas.
Description
The utility model relates to splendid attire or stores the pressurized container of liquefied gas at low temp, is specially the liquefied gas at low temp basin.
At present, splendid attire or the employed basin of storage liquefied gas at low temp (nitrogen, oxygen, helium etc.) are that jar is built-in with basin in outside one, are equipped with the cavity that vacuumizes between interior basin and the outer jar, and the bottom of interior basin and top are connected with indusion tube and blow-down pipe.This liquefied gas at low temp basin is after being full of liquid gas, top in interior basin jar has a certain amount of low temperature gasification gas all the time, and this part gasifying gas is utilized emptying because of not reclaiming, not only waste gas, influenced the availability of basin again.
The purpose of this utility model provides a kind of liquefied gas at low temp basin, the low temperature gasification gas that this basin can have the jar internal upper part is recycled into liquid gas and is fully utilized, not only can avoid gasifying gas emptying and waste, also improve the effective rate of utilization of basin.
To achieve these goals, the utility model is a kind of improvement to existing liquefied gas at low temp basin, a gasifying gas is set in interior basin cools back receptacle, bottom in interior basin is provided with one and reclaims liquefied gas tank, and gasifying gas cools back and is equipped with on the receptacle connecting tube that is connected with gas blow-down pipe and recovery liquefied gas tank respectively.
Effect and the advantage that the utlity model has are:
1, gasifying gas in the basin can be recovered as liquid gas fully, not only avoided fully because the loss and waste of the emptying of gasifying gas, and the liquid gas after reclaiming also can utilize again, improved the liquefied gas at low temp effective rate of utilization and reached 30-35%, has the certain economic effect.
2, reasonable in design, simple in structure, make easily, be easy to be extended and applied.
Below in conjunction with accompanying drawing and with embodiment the utility model is done to be described in detail.
Fig. 1: structural representation of the present utility model
The utility model is by interior basin 2, form for outer jar 1, be connected with connecting band 4 and be equipped with between interior basin 2 and the outer jar 1 and vacuumize cavity 3, be connected with the gasifying gas blow-down pipe 7 that is equipped with valve 7 on it on the interior basin 2 and be connected with the carrier pipe 13 that is equipped with valve 12 on it, it is characterized in that: in interior basin 2, be provided with gasifying gas and cool back receptacle 10, be provided with recovery liquefied gas tank 15 in the underpart of interior basin 2, gasifying gas cools back on the receptacle 10, be equipped with the last connecting tube 5 that has valve 6 on it and be connected with gasifying gas blow-down pipe 7, with be equipped with and reclaim the lower communicating tube 11 that liquefied gas tank 15 is connected, reclaim and to be equipped with the vomit pipe 17 that has valve 16 on it on the liquefied gas tank 15 and to be equipped with gas equalizing line 18.
When using this basin splendid attire or storing liquid gas, at first by carrier pipe 13 inside basin 2 internal-filling liquid oxidizing gases, when being full of liquid gas in the interior basin 2, on interior basin 2 tops, there is a large amount of low temperature gasification gas, open the valve 6 on connecting tube 5, gasifying gas just cools back in the receptacle 10 via entering blow-down pipe 7 and last connecting tube 5 gasifying gas, enter under the cold service that gasifying gas cools back the liquid gas of gasifying gas in interior basin 2 in the receptacle 10 and be liquefied as liquid gas, liquid gas flows into by lower communicating tube 11 again and reclaims in the liquefied gas tank 15, and the liquid gas of opening valve 16 recovery on the vomit pipe 17 is just available.
Claims (2)
1, a kind of liquefied gas at low temp basin, be by interior basin (2), outer jar (1) is formed, be connected with connecting band (4) and be equipped with between interior basin (2) and outer jar (1) and vacuumize cavity (3), be connected with the gasifying gas blow-down pipe (7) that is equipped with valve (8) on it on the interior basin (2) and be connected with the carrier pipe (13) that is equipped with valve (12) on it, it is characterized in that: in interior basin (2), be provided with gasifying gas and cool back receptacle (10), be provided with recovery liquefied gas tank (15) in the underpart of interior basin (2), gasifying gas cools back on the receptacle (10), be equipped with the last connecting tube (5) that has valve (6) on it and be connected with gasifying gas blow-down pipe (7), with be equipped with and reclaim the lower communicating tube (11) that liquefied gas tank (15) is connected, reclaim on the liquefied gas tank (15) and be equipped with the vomit pipe (17) that has valve (16) on it and be equipped with gas equalizing line (18).
