Problems solved by technology

[0003] Some existing industrial gas pressures are high, and the transportation of cryogenic liquids needs to be realized by supercharging in the transportation pipeline through cryogenic booster pumps. However, the investment in this method of transportation equipment is expensive, and the use of supercharging When the pump is pressurized, there are losses such as cooling pump discharge, start-up dissipation and overpressure dissipation, and the loss and waste of cryogenic liquid is relatively large

Abstract

The invention discloses a safe and low-energy-consumption cryogenic liquid output pressurization system. The system is used for pressurization of cryogenic liquid in an output pipeline of a cryogenicliquid storage tank and comprises a first pressurization device and a central control box, and the first pressurization device comprises a first pressurization tank and a first heater; a first electromagnetic valve is arranged on a pipeline for communicating a first liquid inlet with a first pressurization outlet; and the first pressurization tank is further provided with a first pressurization output pipe, the inlet end of the first pressurization output pipe is located in the first pressurization tank and is close to the bottom of the first pressurization tank, and the outlet end of the first pressurization output pipe extends out of the top of the first pressurization tank and communicates with the cryogenic liquid conveying pipeline. According to the safe and low-energy-consumption cryogenic liquid output pressurization system, the physical characteristic that the gas-liquid ratio of the cryogenic liquid is high is utilized, the cryogenic liquid is vaporized through the heater, thevaporized cryogenic liquid with the expanded volume is introduced into the pressurization tank, and therefore the pressurization output effect of the cryogenic liquid is achieved.

Description

technical field [0001] The invention relates to the technical field of cryogenic liquid storage, in particular to a safe and low-energy-consumption cryogenic liquid output pressurization system. Background technique [0002] Cryogenic liquids are liquid gases obtained by condensation below -100°C, including liquid oxygen, liquid nitrogen, liquid argon, liquid helium, liquid hydrogen, and liquefied natural gas. [0003] Some existing industrial gas pressures are high, and the transportation of cryogenic liquids needs to be realized by supercharging in the transportation pipeline through cryogenic booster pumps. However, the investment in this method of transportation equipment is expensive, and the use of supercharging When the pump is pressurized, there are losses such as cooling pump discharge, start-up dissipation and overpressure dissipation, and the loss and waste of cryogenic liquid is relatively large. Contents of the invention [0004] The purpose of the present in...
