Abstract
Description
Technical Field
[0001] This utility model relates to the field of fluid equipment technology, specifically to a cryogenic liquid-gas-liquid separation device. Background Technology
[0002] With the continuous development of the national economy and the increasing pace of industrialization, industrial equipment has developed rapidly, leading to a continuous rise in demand for cryogenic liquids. Currently, the gas-liquid separation devices used in cryogenic liquid transportation employ mechanical separation methods, utilizing the rise in liquid level to seal the outlet and achieve gas-liquid separation. However, using liquid level rise for separation has many drawbacks. For example 1: the sealing surface cannot seal well, resulting in leakage. For example 2: temperature control cannot be achieved when using cryogenic energy, leading to waste of cryogenic raw materials.
[0003] Currently, cryogenic liquid-gas separation devices mainly utilize the rise in liquid level to mechanically open or close valves. However, mechanical sealing requires reducing the sealing surface to achieve a better seal, resulting in a small output pipe diameter and preventing large-diameter discharge. Therefore, how to achieve both good sealing and large-diameter discharge in gas-liquid separation is the problem that this patented technology needs to solve. Utility Model Content
[0004] The technical problem solved by this utility model is to provide a solution to the problems mentioned in the background art.

[0006] A fogging net is installed within the internal volume 2, a safety valve is installed on the gas outlet pipe, and an electrically controlled valve I and an electrically controlled valve II are also installed on the gas outlet pipe.
[0007] Furthermore, the temperature sensor, solenoid valve I, and solenoid valve II are connected to the control unit via signal lines.
[0008] Furthermore, the electrically controlled valve I and electrically controlled valve II are connected in parallel.
[0009] Compared with the prior art, the beneficial effects of this utility model are: the cryogenic liquid separation device satisfies the requirements of good sealing and large-diameter discharge for gas-liquid separation, and utilizes temperature control to better control and avoid waste, thereby improving the safety of use and significantly reducing labor costs.

For example, they can be fixed connections, detachable connections, or integral connections; they can be mechanical connections or electrical connections; they can be direct connections or indirect connections through an intermediate medium; and they can be internal connections between two components.
[0013] like Figure 1 As shown, a cryogenic liquid-gas-liquid separation device includes an internal volume 2, a liquid inlet 1 disposed below the internal volume 2, a gas outlet 11 disposed on one side above the internal volume 2, a temperature sensor 5 disposed on the other side above the internal volume 2, an outer wall 13 disposed on the outside of the internal volume 2, and a vacuum jacket 3 disposed on the outside of the outer wall 13.

A first-level set value and a second-level set value are set in the control unit 9. When the temperature in the temperature sensor 5 reaches the first-level set value, the solenoid valve I7 opens. When the temperature in the temperature sensor 5 reaches the second-level set value, the solenoid valve II opens, and vice versa.
