[0002] A gas-liquid separator is a device used to separate gas and liquid. Its main function is to separate gas and liquid from each other, prevent liquid from entering the gas pipeline or equipment, and ensure the normal operation of the system or equipment; or to separate gas and liquid from the gas-liquid mixture, collect gas, and discharge or circulate liquid. In various industrial fields, gas-liquid separators are widely used in the separation of liquid and gas. The gas-liquid separator separates the gas and liquid in the gas-liquid mixture based on the working principle of the density difference between gas and liquid and the fluid dynamic effect.

[0024] Embodiment 1:

[0025] In this embodiment, a gas-liquid separation device, such as Figure 1 As shown, it includes a separator and a liquid storage barrel 1. Specifically, a barrel cover 2 is provided on the top of the liquid storage barrel 1, and the barrel cover 2 is provided with a mounting hole 3. The separator is installed on the barrel cover 2 and extends into the liquid storage barrel 1 through the mounting hole 3. The separator includes a collecting barrel 4 and a separation barrel 5 arranged in the collecting barrel 4. The barrel wall of the separation barrel 5 is evenly provided with a plurality of grid holes 6 for flowing out the gas-liquid mixture. The bottom end of the collecting barrel 4 is open and the top end is provided with an end plate 7. The end plate 7 is detachably connected to the barrel cover 2. The separated liquid is collected into the liquid storage barrel 1 through the bottom open end of the collecting barrel 4. The top end of the separation barrel 5 is open and the bottom end is closed. The top end of the separation barrel 5 is fixedly connected to the end plate 7. The end plate 7 is provided with a liquid inlet hole 8 and an exhaust hole 9. The liquid inlet hole 8 is connected with the separation barrel 5, and the exhaust hole 9 is connected with the collecting barrel 4.

[0026] With this structure, the gas-liquid mixture enters the separation cylinder 5 through the liquid inlet hole 8, and then flows out from the grid hole 6 into the collecting cylinder 4. The liquid therein sinks due to gravity and is collected in the liquid storage barrel 1, and the gas rises, gathers and is discharged from the exhaust hole 9, thereby separating the gas and liquid. The structure is simple and easy to operate, and the separation efficiency is high, making the utility model more practical.

[0027] In this embodiment, the outer diameter of the end plate 7 is larger than the outer diameter of the collecting cylinder 4. The collecting cylinder 4 is configured so that it can extend into the liquid storage barrel 1 through the mounting hole 3, and the outer edge of the end plate 7 can overlap the barrel cover 2, wherein a flexible seal is provided at the position where the end plate 7 connects with the barrel cover 2 to ensure the sealing of the liquid storage barrel space, and the flexible seal is preferably an annular sealing gasket.

[0028] As an optimization, the wall of the collecting cylinder 4 near the end plate 7 is provided with an external thread, and the mounting hole 3 is provided with an internal thread. The collecting cylinder 4 is detachably screwed to the barrel cover 2 through the cooperation of the external thread and the internal thread, so that the separator can be detachably fixed on the barrel cover 2. Of course, bolts can also be installed at a position near the outer edge of the end plate 7 to connect the barrel cover 2. The internal thread and the external thread are sealed to ensure the gas sealing of the space of the collecting cylinder 4. The sealing method can be a sealing O-ring, thread glue, or raw tape, etc.

[0029] In order to facilitate the disassembly and assembly of the collecting tube 4, the end plate 7 is configured as a regular polygonal structure, so that it is convenient to use a tool such as a wrench to screw the end plate 7 and quickly disassemble and assemble the separator.

[0030] In this embodiment, the length of the above-mentioned separation cylinder 5 is smaller than that of the collecting cylinder 4, which extends the falling distance of the liquid and increases the gas-liquid separation time and efficiency. In addition, the diameter of the above-mentioned separation cylinder 5 is approximately half of the above-mentioned collecting cylinder 4, so that there is a larger gas-liquid separation space between the outer wall of the above-mentioned separation cylinder 5 and the inner wall of the collecting cylinder 4.

[0031] As an optimization, the bottom of the collecting cylinder 4 is suspended so that the sinking liquid can quickly enter the liquid storage barrel 1 through the bottom opening of the collecting cylinder 4 .

[0032] In this embodiment, a liquid outlet 10 is provided on the barrel wall of the liquid storage barrel 1, and the separated liquid is discharged through the liquid outlet 10.

[0033] According to a preferred embodiment, it also includes a circulation pump 11, a liquid outlet pipe 12 and a liquid inlet pipe 13, one end of the above-mentioned liquid outlet pipe 12 is connected to the liquid outlet 10 and the other end is connected to the liquid inlet end of the circulation pump 11, one end of the above-mentioned liquid inlet pipe 13 is connected to the liquid inlet hole 8 and the other end is connected to the liquid outlet end of the circulation pump 11 through the reaction system. In this way, the gas-liquid mixture generated by the reaction system enters the separator through the above-mentioned liquid inlet pipe 13, and the separated liquid is then refluxed into the reaction system through the above-mentioned liquid outlet pipe 12 and the circulation pump 11, thereby realizing the recycling and reuse of the liquid. Taking a flat-plate photochemical reaction system as an example, sunlight is used as a light source, and the catalyst material is loaded on the material, or the catalyst is loaded in the form of a membrane or a porous medium, and the carrier is spread flat in a flat-plate reactor 14. The solution required for the photochemical reaction can be stored in the above-mentioned liquid storage barrel 1. The above-mentioned circulation pump 11 is used to transport the reaction solution to the flat-plate reactor 14 through the above-mentioned liquid outlet pipe 12 for photocatalytic reaction. Then, the gas-liquid mixture containing the reaction solution and the reaction product is passed into the above-mentioned liquid inlet pipe 13 and enters the enterprise separation device. After efficient gas-liquid separation, the gas rises, is collected and discharged, and the reaction solution settles downward and is collected in the above-mentioned liquid storage barrel 1 for recycling in the photochemical reaction.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
