Description

Technical Field

[0001] This application relates to the technical field of moisture removal devices for gas containers, and particularly to a gas-liquid separation device for pressure vessels. Background Art

[0002] During the transportation and filling process of pressurized gas, a certain amount of moisture will remain inside. Especially during the pressurized filling process, water vapor will continue to condense. At this time, the liquid will occupy the internal space of the tank, affecting the load capacity of the tank. Therefore, it is necessary to treat the gas before filling the pressure vessel to separate the liquid components, which is also a common existing method; in the existing separation devices, the gas-liquid separator is a commonly used separation equipment. By rotating and decelerating the gas once, the liquid components in the pipeline can be significantly reduced. However, after the existing gas-liquid separation device is used for a period of time, more liquid will adhere to its inner wall. Since there are also some organic solvents in the organic gas, it is relatively easy to affect the separation effect of the gas-liquid separator, resulting in separation failure and loss of separation effect. Then, it is necessary to disassemble and clean it, which affects the production process. At the same time, disassembling the pressure vessel also has certain risks. Therefore, it is necessary to improve the existing structure to solve these problems. Summary of the Invention

Detailed Description of the Embodiment

[0019] The following further describes the present application in detail with reference to the drawings.

[0020] In order to more clearly understand the technical solutions shown in the embodiments of the present application, first, the working principle of the existing gas-liquid separation device for a pressure vessel is introduced.

[0021] The existing gas-liquid separation device for pressure vessels is connected to the gas transmission pipeline. After the gas is introduced into the separation device, the gas rotates, and at the same time, its space becomes larger, causing the gas flow rate to slow down. Then, under the conditions of rotation and pressure reduction, moisture and liquid will move downward along the inner wall of the separator, while the gas is discharged from the top of the separator to achieve the separation process. However, after using for a period of time, there are more impurities adhering to the inside of the separator, and even the lower end of the separator is blocked, making it impossible to separate the liquid. This requires manual disassembly to flush and clean the inside of the separator, which leads to a slowdown in production. At the same time, disassembling and assembling the pressure gas pipeline, especially when transporting some flammable gases, poses a greater safety hazard. Therefore, it is necessary to improve the existing separation device to solve these existing problems.
