LNG cold energy recovery ice making system and method

Abstract

The invention discloses a LNG cold energy recovery ice making system and method. According to the technical scheme, the LNG cold energy recovery ice making system comprises a gasification tank, the two sides of the gasification tank are fixedly connected with a liquid inlet pipe and a gas outlet pipe correspondingly, and a sealing mechanism is arranged at one end of the gas outlet pipe; and the sealing mechanism comprises an ice making tank, a movable part is arranged at the end, away from the gasification tank, of the gas outlet pipe, a first sliding groove is formed in the side, away from the gasification tank, of the movable part, a limiting plate is fixedly connected to the outer side of the end, away from the gasification tank, of the gas outlet pipe and arranged inside the first sliding groove and slidably connected with the movable part, T-shaped blocks are fixedly connected to the two ends of the side, away from the gasification tank, of the movable part, second sliding grooves are formed in the two ends of one side of the ice making tank, and the T-shaped blocks are arranged inside the second sliding grooves and are in sliding connection with the ice making tank. The LNG cold energy recovery ice making system and the method have the beneficial effects that the problem that most of the existing LNG cold energy ice making processes are operated in two steps, gasified cold energy is easily dissipated, and therefore resource waste is caused is solved.

Description

technical field [0001] The invention relates to the technical field of LNG cold energy ice making, in particular to an ice making system and method for recovering LNG cold energy. Background technique [0002] LNG cold energy ice making is to generate a large amount of cold energy after the liquid natural gas is vaporized through heat conversion, so as to freeze the water source to make ice. [0003] In the existing LNG cold energy ice-making process, the gasification and ice-making operations are carried out in two steps. First, the liquid natural gas is gasified, and after the gasification, the water source is made into ice, so that the cold energy after gasification will be It will be emitted during transportation, resulting in serious waste of resources. Contents of the invention [0004] To this end, the present invention provides a system and method for recovering LNG cold energy to make ice. Through the movable socket between the L-shaped ring block and the built-i...

Problems solved by technology

[0004] To this end, the present invention provides a system and method for recovering LNG cold energy to make ice. Through the movable socket between the L-shaped ring block and the built-in groove, and the setting of the elastic ball, the gap between the air outlet pipe and the air inlet can be effectively adjusted. The space is sealed to avoid gas leakage. At the same time, through the setting of the sealing mechanism, the installation and disassembly between the ice making tank and the gas outlet pipe can be carried out effectively and simply, so as to solve the problem that most of the existing LNG cold energy ice making process is passed. The two-step operation is easy to cause the cold energy of gasification to be dissipated, which leads to the waste of resources
