A kind of LNG cold energy recovery ice making system and method

Abstract

The invention discloses an ice-making system and method for recovering LNG cold energy. The technical proposal is as follows: a gasification tank is included, a liquid inlet pipe and an air outlet pipe are fixedly connected to both sides of the gasification tank, and a sealing mechanism is provided at one end of the air outlet pipe; The sealing mechanism includes an ice-making tank, a movable part is provided at the end of the air outlet pipe far away from the gasification tank, and a first sliding groove is provided on the side of the movable part far away from the gasification tank, and the outer side of the air outlet pipe far away from the gasification tank is fixedly connected with a limit plate. The plate is located inside the first sliding groove and is slidably connected with the movable part. The two ends of the movable part away from the gasification tank are fixedly connected with T-shaped blocks, and the two ends of the ice-making tank are provided with a second sliding groove, which is T-shaped. The block is arranged inside the second sliding groove and is slidably connected with the ice-making tank. An LNG cold energy recovery ice-making system and method have the beneficial effects: it solves most of the two-step operations in the existing LNG cold energy ice-making process, and is easy The cold energy that causes gasification is dissipated, which leads to the problem of waste of resources.

Description

technical field [0001] The invention relates to the technical field of LNG cold energy ice-making, in particular to an LNG cold energy recovery ice-making system and method. Background technique [0002] LNG cold energy ice making is to gasify liquid natural gas through heat conversion to generate a large amount of cold energy, 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 ice, so that the gasified cold energy will be It will be emitted during transportation, resulting in a serious waste of resources. SUMMARY OF THE INVENTION [0004] Therefore, the present invention provides an LNG cold energy recovery ice-making system and method. Through the movable sleeve between the L-shaped ring block and the built-in groove, and the arrangement of the elas...

AI Technical Summary

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
