Abstract

The invention discloses a liquefied natural gas supply system which comprises a storage tank, a gas inlet pipe is arranged on the outer wall of the top of the storage tank, a vaporizer is arranged on the inner wall of the gas inlet pipe, an exhaust pipe is arranged at the position, close to the bottom, of the outer wall of one side of the storage tank, a heater is arranged in the exhaust pipe, and a blow-off pipe is arranged on the outer wall of the bottom of the storage tank. Valves are arranged on the outer wall of the blow-off pipe and the outer wall of the exhaust pipe, an overflow mechanism is arranged at the position, close to the top, of the inner wall of the storage tank, the overflow mechanism comprises a fixing ring and a plurality of overflow pieces, the overflow pieces are fixed to the fixing ring at equal intervals, and the overflow pieces are made of elastic materials. According to the system, the situation that gas supply of natural gas is affected due to backflow of the natural gas caused by too much natural gas in the storage tank is prevented, the situation that liquidity of the natural gas is poor due to gathering of the natural gas is prevented, the natural gas can be filtered and purified, and the situation that dust is doped in the natural gas to affect gas supply of the natural gas is prevented.

Description

technical field [0001] The invention relates to the technical field of natural gas supply, in particular to a liquefied natural gas supply system. Background technique [0002] Liquefied natural gas is natural gas that is liquid under normal pressure after a series of ultra-low temperature liquefaction after purification of the natural gas produced in the gas field. It is recognized as the cleanest fossil energy on earth. Its main component is methane, which is colorless, odorless and non-toxic And non-corrosive, its volume is about 1 / 625 of the same volume of gaseous natural gas, and its mass is only about 45% of the same volume of water. The LNG gas supply system generally includes storage tanks, vaporizers, heaters and other components. For storing liquefied natural gas, the vaporizer is used to convert part of the liquefied natural gas in the storage tank into natural gas, and the heater is used to heat the natural gas converted by the vaporizer to a suitable temperature...
