Abstract
The utility model discloses a tank car waste gas recovery device. The device comprises a sealed and hollow recovery tank and is characterized in that the recovery tank is provided with a waste gas inlet which is in a pipeline connection with a tank car, and a first valve is arranged on the waste gas inlet. According to the tank car waste gas recovery device, waste gas of the tank car is recovered by the aid of a sealed tank body at the normal pressure, the recovered waste gas is fed into a gas liquefaction device for reprocessing, and the recovered waste gas is reprocessed to be a liquid for reuse. The tank car waste gas recovery device has the advantages that the danger during the process of discharging the waste gas is avoided, the cost is saved, and the device is safe and environment-friendly and the like.
Description
Technical field
The utility model belongs to special gas processing can field, relates to a kind of groove tank car waste gas recovering device.
Background technique
The groove tank car is a kind of special vehicle that is used for the chemical solution transportation, comprises transportation liquid nitrogen, liquid oxygen etc.Chemical solution in the groove tank car by packing after, often go back the waste gas of nubbin high pressure in the tank body, this waste gas is if liquid nitrogen or liquid oxygen etc. are directly entered atmosphere to empty tank body through regular meeting.There is certain risk in this processing mode, need select spacious and unmanned zone during discharging, and has bigger waste, especially for a large-scale groove tank car fleet.Accumulate over a long period, the amount of this discharging is just very huge.How to eliminate the dangerous of toxic emission and be various special gases processing producer problem demanding prompt solution the waste gas recycling.
Summary of the invention
The utility model provides a kind of solution of the above problems, provides a kind of simple in structure, the groove tank car waste gas recovering device of safety and environmental protection.
The technological scheme of the utility model is a kind of groove tank car waste gas recovering device; It comprises the recycling can of the hollow of sealing; It is characterized in that: but said recycling can is provided with the exhaust gas entrance of a pipeline connecting groove tank car, and said exhaust gas entrance is provided with first valve.
Preferably, said recycling can two the hemispheric upper bottom portion and the lower bottom part that comprise tubular middle part and said middle part is sealed up and down.
Preferably, said first valve is a safety check.
Preferably, also be provided with waste gas outlet on the said recycling can, said waste gas outlet pipeline connects gas liquefaction system, and said waste gas outlet is provided with second valve.
Preferably, said second valve is a safety check.
The sealed shell of tank that a kind of groove tank car waste gas recovering device of the utility model utilizes a normal pressure reclaims the waste gas of groove tank car, and the waste gas that reclaims is sent into gas liquefaction system reprocess, and is processed into liquid again and utilizes again.Thereby the danger when having avoided discharging waste gas, and the cost of practicing thrift.It has advantages such as safety and environmental protection.
Description of drawings
Fig. 1 is to use the structural representation of a kind of groove tank car waste gas recovering device of the utility model.
Embodiment
Embodiment in the face of the utility model is described in further detail down.
As shown in Figure 1, a kind of groove tank car waste gas recovering device of the present invention comprises the recycling can 10 of the hollow of sealing, two hemispheric upper bottom portion 14 and lower bottom part 16 that recycling can 10 comprises tubular middle part 12 and middle part 12 is sealed up and down.The tank body of other shapes can certainly be adopted, present embodiment can not be confined to.But recycling can 10 is provided with the exhaust gas entrance 18 of a pipeline connecting groove tank car (not shown), and exhaust gas entrance 18 is provided with first valve 20.Also be provided with waste gas outlet 22 on the recycling can 10, waste gas outlet 22 pipelines connect gas liquefaction system (not shown), and waste gas outlet 22 is provided with second valve 24.
A kind of groove tank car waste gas recovering device of the present invention only need be opened exhaust gas entrance 18 connecting groove tank cars first valve 20 and got final product in use.Exhaust gas pressure in the groove tank car is high, is injected into automatically in the recycling can 10, and first valve 20 is that safety check avoids waste gas to recharge in the groove tank car.Gas liquefaction system connects waste gas outlet 22, and produces negative pressure the waste gas in the recycling can 10 are taken away, so that be processed into liquid again.Second valve 24 also is a safety check, avoids the waste gas in the gas liquefaction system to pour in down a chimney in recycling can 10.
Above embodiment is merely the utility model a kind of mode of execution wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
Claims (5)
