Embodiment 1

[0024] Embodiment 1: power output

[0025] Such as figure 1 As shown, the low temperature heat preservation liquid storage tank 1 is filled with low temperature liquid, and the outlet of the low temperature heat preservation liquid storage tank is connected to the hydraulic pump 2 . The output port of the hydraulic pump is connected to the first-stage cooling and evaporating heat exchanger 3 through a one-way valve 4. The heat exchanger unit is called the final refrigeration evaporative heat exchanger. A one-way valve 4 is provided between the two-stage refrigeration evaporative heat exchanger units, and a check valve is connected to the inlet end of the first-stage refrigeration evaporative heat exchanger unit; The outlet is connected to the inlet of the pneumatic motor 5, and the outlet of the pneumatic motor 5 is connected to the circulation return pipe 6, and the circulation return pipe is connected to the low-temperature heat preservation liquid storage tank 1 through t...

Embodiment 2

[0028] Example 2: Gas delivery

[0029] Such as figure 2 As shown, the structural difference between Embodiment 2 and Embodiment 1 is that the low-pressure gas input pipe 7 is connected to the final refrigeration evaporative heat exchanger unit, and the outlet of the final refrigeration evaporative heat exchanger unit is connected to the high-pressure gas output pipe 8 . The low-pressure gas passes through the last-stage refrigeration evaporative heat exchanger unit and begins to cool down step by step, until the outflow of the first-stage refrigeration evaporative heat exchanger unit has become a low-temperature liquid and enters the low-temperature insulation storage tank, and then passes through the hydraulic pump to transfer the low-temperature liquid from the The low-temperature heat preservation liquid storage tank is pumped out and pressed into the first-stage refrigeration evaporative heat exchanger unit, and the fourth-stage (last stage) refrigeration evaporative hea...

Abstract

The invention relates to a method for carrying out power outputting and gas conveying through low-temperature liquid. The low-temperature liquid stored in a low-temperature insulating liquid storage tank is conveyed to a refrigerating evaporating heat exchanger through a hydraulic pump. The low-temperature liquid is heated, gasified and expanded through the refrigerating heat exchanger, and high-pressure and low-temperature gas is formed. The high-pressure and low-temperature gas output by the refrigerating evaporating heat exchanger drives a pneumatic motor to work, and power output is formed. The low-temperature liquid stored in the low-temperature insulating liquid storage tank is pressed into the refrigerating evaporating heat exchanger through the hydraulic pump, the low-temperature liquid is heated, gasified and expanded through the refrigerating evaporating heat exchanger, and the high-pressure and low-temperature gas is formed and enters a gas conveying pipeline.

Description

technical field [0001] The invention relates to a method for power output and gas delivery using cryogenic liquid. Background technique [0002] There are some special liquids that generate a large amount of low-temperature gas when they are vaporized, and these liquids also generate a lot of pressure while generating low-temperature gas. For example, liquid fluorine, liquid ammonia, liquid carbon dioxide, liquid oxygen, liquid nitrogen, liquid hydrogen, etc., these liquids mentioned above cannot be stored under normal temperature and pressure. It is stored in a low-temperature heat preservation liquid storage tank. When a gas becomes a liquid, its volume decreases and its density increases. Once these liquids encounter normal temperature, they will immediately vaporize, evaporate and expand, and when a large amount of low-temperature gas is produced, a large amount of pressure will be generated at the same time. [0003] Traditional gas transportation is accomplished usi...
