Description

Technical Field

[0001] This utility model relates to the field of MVR evaporation technology, and in particular to a gas-liquid separation device for MVR evaporation. Background Technology

[0002] In industries such as chemicals, pharmaceuticals, and petrochemicals, MVR (Mechanical Vapor Recompression) evaporation technology has been widely used due to its high efficiency and energy saving characteristics. MVR evaporation systems provide a heat source by compressing and reusing the secondary steam generated within the system, which significantly reduces energy consumption.

[0003] In existing MVR evaporation processes, especially when processing materials containing a large amount of water vapor, condensation often occurs on the inner surface of the separator. These condensation beads remain suspended and adhere to the inner wall of the separator for a long time, which not only affects the evaporation efficiency, but may also cause corrosion to the equipment, increase maintenance costs, and even affect the quality and purity of the product.

[0004] Therefore, a gas-liquid separation device for MVR evaporation has been developed that can scrape off condensates suspended at the top of the tank to avoid affecting evaporation efficiency and improve the service life of the separator. Utility Model Content

[0005] To overcome the shortcomings of existing MVR evaporation processes where condensation often occurs on the inner surface of the separator, which not only affects evaporation efficiency but may also cause corrosion and increase maintenance costs, this invention provides a gas-liquid separation device for MVR evaporation that can scrape off condensation suspended at the top of the separator, thereby avoiding impact on evaporation efficiency and improving the service life of the separator.

[0006] Technical solution: A gas-liquid separation device for MVR evaporation includes a separation tank, an inlet pipe, an outlet pipe, a liquid collection filter, a liquid outlet pipe, a solenoid valve, and a liquid guide pipe. The inlet pipe is connected to the left side of the separation tank, the outlet pipe is connected to the right side of the separation tank, the liquid collection filter is connected to the lower side of the separation tank, the liquid outlet pipe is connected to the lower side of the liquid collection filter, the solenoid valve is installed on the liquid outlet pipe, and the liquid guide pipe is connected inside the separation tank.

[0007] Furthermore, it is particularly preferred that both the intake pipe and the exhaust pipe are connected to flanges.

[0008] In addition, it is particularly preferred that a flow channel is opened on the right side of the liquid guide tube.

[0009] In addition, it is particularly preferred that the device also includes a cyclone plate, a support frame, a fan, and a connecting frame. The cyclone plate is connected to the outside of the liquid guide tube and is connected to the inner wall of the separator. The support frame is connected to the inside of the air inlet tank, and the fan is rotatably connected to the support frame. The connecting frame is connected to the right side of the fan.

[0010] Furthermore, it is particularly preferred that the connecting frame has a diamond-shaped structure.

[0011] Furthermore, it is particularly preferred that the container also includes a top plate, a connecting column, a rotating frame, and a torsion spring. The connecting column is connected to the top of the separator, the rotating frame is rotatably connected to the connecting column, the torsion spring is connected between the rotating frame and the connecting column, the top plate is rotatably connected to the lower outer side of the connecting column, the top plate is slidably connected to the liquid guide pipe, the top plate is press-fitted with the connecting frame, and the top plate is press-fitted with the rotating frame.

[0012] Compared with the prior art, the present invention has the following advantages: After the fan is started, the support rotates, causing the top plate to move upward. Then, through the squeezing and cooperation between the top plate and the rotating frame, the rotating frame rotates to scrape off the condensate on the top of the separator, thus achieving the effect of scraping off the condensate suspended on the top of the separator, avoiding affecting the evaporation efficiency and improving the service life of the separator.

Detailed Implementation

[0017] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0018] A gas-liquid separation device for MVR evaporation, such as Figures 1-3As shown, the system includes a separator 1, an inlet pipe 2, an outlet pipe 3, a liquid collection filter 4, a liquid outlet pipe 5, a solenoid valve 6, a liquid guide pipe 7, a cyclone plate 8, a support frame 9, a fan 10, a connecting frame 11, a top plate 12, a connecting column 13, a rotating frame 14, and a torsion spring 15. The inlet pipe 2 is connected to the left side of the separator 1, and the outlet pipe 3 is connected to the right side. Both the inlet pipe 2 and the outlet pipe 3 are connected to flanges. The liquid collection filter 4 is connected to the lower side of the separator 1, and the liquid outlet pipe 5 is connected to the lower side of the liquid collection filter 4. A solenoid valve 6 is installed on the liquid outlet pipe 5. The liquid guide pipe 7 is connected inside the separator 1, and a guide groove is opened on the right side of the liquid guide pipe 7. A cyclone plate 8 is connected to the outside of the liquid pipe 7. The cyclone plate 8 is connected to the inner wall of the separator 1. A support frame 9 is connected inside the air inlet tank. A fan 10 is rotatably connected to the support frame 9. A connecting frame 11 is connected to the right side of the fan 10. The connecting frame 11 has a diamond-shaped structure. A connecting column 13 is connected to the top inside the separator 1. A rotating frame 14 is rotatably connected to the connecting column 13. A torsion spring 15 is connected between the rotating frame 14 and the connecting column 13. A top plate 12 is rotatably connected to the lower outer side of the connecting column 13. The top plate 12 is slidably connected to the liquid guide pipe 7. The top plate 12 is squeezed into the connecting frame 11 and the rotating frame 14.

[0019] When using this invention, first move the separator 1 to the gas-liquid separation area of ​​the MVR, then connect the inlet pipe 2 and outlet pipe 3 to the MVR evaporator, so that the gas-liquid mixture enters the separator 1 from the inlet pipe 2. Under the obstruction of the liquid guide pipe 7 and the guidance of the cyclone plate 8, a swirling effect is generated, causing the liquid in the gas-liquid mixture to be thrown against the inner wall of the separator 1 under centrifugal force, and then slide down the lower part of the separator 1 into the liquid collection filter 4. After being filtered by the liquid collection filter 4, it flows into the outlet pipe 5. By opening the solenoid valve 6, the separated liquid in the outlet pipe 5 can be removed. At the same time, the gas separated by centrifugation will flow back into the upper part of the separator 1 from the liquid guide pipe 7. When the gas-liquid mixture enters the outlet pipe 3, start the fan 10 on the support frame 9 to make the fan 10 rotate, accelerating the flow speed of the gas-liquid mixture, thereby improving the gas-liquid separation effect. The separated gas then enters the separator 1. After the top part is removed, condensate may form at the top of the separator 1. When the fan 10 is started, the support rotates. Through the pressing fit between the support frame 9 and the top plate 12, the top plate 12 moves upward. Then, through the pressing fit between the top plate 12 and the rotating frame 14, the rotating frame 14 rotates on the connecting column 13. The torsion spring 15 is compressed and contracts, causing the rotating frame 14 to rotate and scrape off the condensate at the top of the separator 1. The scraped water droplets will flow into the liquid collection filter 4 along the guide groove on the right side of the liquid guide pipe 7, and then into the liquid outlet pipe 5. Afterward, the connecting frame 11 rotates and disengages from the top plate 12, causing the top plate 12 to move downward. The torsion spring 15 returns to its original position, causing the rotating frame 14 to rotate and reset. This achieves intermittent scraping off of the condensate suspended at the top of the separator 1, thus effectively removing the condensate suspended at the top of the tank, avoiding affecting the evaporation efficiency, and improving the service life of the separator 1.
