Description

Vehicle-mounted natural gas bottle recovery equipment Technical Field The utility model belongs to the technical field of natural gas recovery, and particularly relates to vehicle-mounted natural gas cylinder recovery equipment. Background The vehicle-mounted natural gas cylinder is generally referred to as a CNG gas cylinder, namely, natural gas is compressed to a high pressure state and stored in the gas cylinder, and the pressure can reach 20-25MPa. CNG cylinders are widely used in natural gas driven vehicles such as CNG buses, taxis and private automobiles. These cylinders are typically installed in the interior of the vehicle or at the rear of the vehicle for storing compressed natural gas for powering during travel. When the CNG gas cylinder is scrapped or recovered, the CNG gas cylinder is generally delivered to a natural gas company or a gas station for recovery, when the CNG gas cylinder is recovered, a lot of natural gas still remains in the CNG gas cylinder, the natural gas in the gas cylinder is generally emptied, then the bottom of the gas cylinder is punched and recovered, at present, when the residual gas of the gas cylinder is exhausted, no special exhaust equipment is generally arranged, the common method is to bring the gas cylinder to an open area with good ventilation state, the gas cylinder is opened to directly discharge the residual gas in the gas cylinder, the residual natural gas can be quickly scattered into the atmosphere, and the other method is to burn off the residual gas by a pipeline connection flame gun and other tools, so that the two methods are wasted and the gas in the gas cylinder cannot be recovered and reused. Disclosure of utility model Aiming at the problems, the utility model aims to provide vehicle-mounted natural gas cylinder recovery equipment, which solves the problems that at present, when residual gas in a gas cylinder is exhausted, no special exhaust equipment is generally available, the common method is to bring the gas cylinder to an open area with good ventilation state, the residual gas in the gas cylinder is directly discharged by opening the gas cylinder, the residual natural gas can be quickly dispersed into the atmosphere, and the other method is to burn off the residual gas by a combustion method through connecting a tool such as a flame gun and the like, and the two methods are wasted and can not recycle the gas in the gas cylinder. In order to achieve the above purpose, the vehicle-mounted natural gas cylinder recycling device comprises a supporting plate, wherein a storage battery is arranged on one side of the upper side of the supporting plate, a control box is arranged on one side of the storage battery, a compressor is arranged on one side of the storage battery, an air cooler is arranged at the output end of the compressor in a communicated mode, a recycling gas cylinder is arranged at the output end of the air cooler in a communicated mode, a supporting frame is arranged on the lower side of the recycling gas cylinder, and the supporting frame is fixedly arranged on the upper side of the supporting plate. The utility model has the beneficial effects that the residual gas enters the compressor, the compressor compresses the residual gas, the gas is compressed into liquid state, the liquid state enters the air cooler through the output end of the compressor, the air cooler rapidly dissipates heat of the gas, and then the gas is sent into the recovery gas cylinder through the recovery tank and the connecting valve to be recovered and stored. In order to reduce the water vapor in the recovered gas; As a further improvement of the technical scheme, the input end of the compressor is communicated with a connecting pipe, one end of the connecting pipe, which is far away from the compressor, is communicated with a dehumidifying box, the dehumidifying box comprises a box body, the connecting pipe is communicated with the upper side of the box body, an air inlet pipe is communicated with the lower side of one side, which is far away from the storage battery, of the box body, a sealing cover is arranged on one side of the upper side of the box body, and moisture absorbent particles are filled in the inner side of the box body.
