Problems solved by technology

[0002] At present, the natural gas storage, transportation and supply system is composed of a gas filling station, a high-pressure gas transport vehicle, and a gas filling sub-station, and the gas filling sub-station also needs to be equipped with a turnover high-pressure gas transport vehicle chassis, a gas loading and unloading device, and a gas storage In addition to occupying the chassis of the turnover high-pressure gas transport vehicle with a price of 1 million yuan, the equipment, gas filling device and other systems are insufficiently unloaded from the on-board storage tank, so that about 20% of the gas cannot be fully unloaded, resulting in round-trip transportation and increased Increased transportation costs, resulting in difficulties in gas supply

Embodiment Construction

[0028] Attached below Figure 1-7 The mobile integrated CNG storage and transportation gas supply device and control method of the present invention will be further explained:

[0029] refer to figure 1

[0030] The mobile integrated high-pressure gas transport vehicle is composed of a vehicle-mounted gas storage tank system 1, a flatbed trailer 2, and a hydraulic automatic unloading system 3. The vehicle-mounted air storage tank system 1 is three independent connectable and detachable gas storage boxes / gas storage tanks, the hydraulic automatic unloading system 3 is placed on the flatbed trailer 2, and the vehicle-mounted air storage tank system 1 is installed on the hydraulic automatic unloading system 3 on.

[0031] refer to figure 2

[0032] The pipeline system includes gas dispenser, 4# explosion-proof pressure transmitter 22, fourth manual ball valve 21, fourth one-way valve 20, filter 25, bus bar 19 and three pipelines connected to the gas storage tank. One singl...

Abstract

The invention relates to a moving integrated CNG (compressed natural gas) storage and transportation gas supplying device and a control method, belonging to the field of integrated CNG transportation, storage and gas supplying devices. The device comprises a moving integrated high-pressure gas transportation vehicle, a gas filling machine installed at a substation, a pipeline system, a station loading hydraulic moving platform gas storage tank system, a control system, wherein the station loading hydraulic moving platform gas storage tank system is connected with the pipeline system; the control system is installed at a gas filling station; the moving integrated high-pressure gas transportation vehicle also comprises a flat dragging vehicle (2), a hydraulic automatic unloading vehicle system (3) and a vehicle loading gas storage tank system (1), and the hydraulic automatic unloading vehicle system (3) is installed on the flat dragging vehicle (2); the vehicle loading gas storage tank system (1) is installed on the hydraulic automatic unloading vehicle system (3). By virtue of arranging a vehicle-loading and station-loading moving device, the CNG gas transportation and storage are integrated, through the controlling of a PLC (programmable logic controller) central control system, the residual gas in an empty can is transported to other storage cans in the platform, and the residual amount of the empty can gas in ensured to not exceed 3%; and the empty residual gas amount is greatly less than 20% of that in the prior art, and the transportation expense and a great deal of energy sources are saved.

Description

technical field [0001] The invention relates to a mobile integrated CNG storage, transportation and gas supply device and a control method thereof, and relates to a compressed natural gas CNG integrated transportation, storage and gas supply device, which is fast, convenient and can maximize the utilization of compressed natural gas CNG. Background technique [0002] At present, the natural gas storage, transportation and supply system is composed of a gas filling station, a high-pressure gas transport vehicle, and a gas filling sub-station, and the gas filling sub-station also needs to be equipped with a turnover high-pressure gas transport vehicle chassis, a gas loading and unloading device, and a gas storage In addition to occupying the chassis of the turnover high-pressure gas transport vehicle with a price of 1 million yuan, the equipment, gas filling device and other systems are insufficiently unloaded from the on-board storage tank, so that about 20% of the gas cannot ...
