LNG/L-CNG skid-mounted gas station

Abstract

The invention discloses a LNG / L-CNG skid-mounted gas station. The LNG / L-CNG skid-mounted gas station comprises a first sled base, a second sled base, a LNG pump sled, a low-temperature storage tank, aL-CNG pump sled and a gas filling machine; the L-CNG pump sled is arranged on the first sled base; the low-temperature storage tank, the L-CNG pump sled and the gas filling machine are integrated onthe second sled base in sequence; an unloading table is additionally arranged at the end, near the gas filling machine, of the second sled base; the end, near the low-temperature storage tank, of thesecond sled base is movably connected with the first sled base; the low-temperature storage tank discharges liquid by the head and tail ends; fences are arranged on two sides of the first sled base and the second sled base; the first sled base is connected with the end, near the low-temperature storage tank, of the second sled base; top cover plates are arranged at the tops of the fences; and thehorizontal plane of the top cover plates is higher than the horizontal plane of the top of the low-temperature storage tank. The LNG / L-CNG skid-mounted gas station has the following beneficial effects: through high integration degree, the country and industry standards are met, and the functions of an integrated gas station are expanded; and through the mode of discharging the liquid by the head and tail ends of the low-temperature storage tank, the generation of BOG is greatly reduced, and the liquid outlet speed is accelerated.

Description

technical field [0001] The invention relates to the field of liquefied natural gas filling, in particular to an LNG / L-CNG skid-mounted filling station. Background technique [0002] Liquefied Natural Gas (Liquefied Natural Gas, usually represented by LNG), as a green and clean energy, is one of the substitutes for traditional fuels. As the government continues to increase its environmental protection requirements for enterprises, the demand for liquefied natural gas is increasing day by day, and more and more enterprises are investing in the LNG filling industry. However, the land for building a station is limited, and it is becoming more and more difficult to go through the procedures for approving land, and it is even more difficult to approve large-scale land. This kind of function integration can also achieve convenient maintenance, and reducing operation and maintenance costs has become the goal of the current natural gas filling industry.
