Description

Technical Field

[0001] This utility model relates to the field of gas-water separator technology, and specifically to a multifunctional gas-water separator. Background Technology

[0002] The multi-stage compression of a piston compressor essentially reduces compression power consumption through "stage-by-stage pressurization and intermediate cooling." During this process, water precipitation is inevitable and must be removed by a gas-liquid separator. Poor separation efficiency of the gas-liquid separator can directly lead to malfunctions such as liquid slugging during subsequent compression.

[0003] Piston compressor main units and pipelines can generate particles due to internal wear, external intrusion, material failure, and abnormal operating conditions, necessitating the installation of various filters in the pipelines. The gas-liquid separator separates liquid water, which is discharged through a drain valve. The filter is installed on the drain pipeline; however, the filter is prone to clogging, shortening the cleaning cycle, and requires periodic removal for cleaning or replacement of the filter element. Utility Model Content

[0004] Based on the above description, this utility model provides a multifunctional gas-water separator to solve the problem in related technologies where filters are easily clogged, shortening the cleaning cycle, and requiring periodic removal of the filter for cleaning or replacement of the filter element.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multifunctional gas-water separator, comprising: a gas-water separator body, with a drain outlet at the bottom; a drain pipe installed at the drain outlet, the drain pipe including an upper inlet pipe, a lower outlet pipe and a side branch pipe, and the three are interconnected; a filter screen horizontally installed in the branch pipe, the two ends of the filter screen being closed, and the axis being located between the inlet pipe and the outlet pipe.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the outer end of the branch pipe is provided with an internal thread, through which a threaded cover plate is installed.

[0008] Furthermore, the threaded cover plate is held against the outer end of the filter screen by a spring.

[0009] Furthermore, the inner end of the filter screen abuts against the inner wall of the drain pipe and is connected to the outlet pipe through a pipeline.

[0010] Furthermore, the filter screen is cylindrical, and there is a space between the outer side and the inner wall of the branch pipe.

[0011] Furthermore, the diameter of the inlet pipe is smaller than the diameter of the outlet pipe.

[0012] Furthermore, the filter screen is a sintered metal filter screen.

[0013] Furthermore, multiple water-blocking columns are arranged parallel to each other on the inner wall of the gas-water separator body, and the water-blocking columns extend in the vertical direction.

[0014] Furthermore, a baffle plate is fixed to the lower end of the water-blocking column, and the baffle plate is fixed to the inner wall of the gas-water separator body. A water-guiding groove is provided on the baffle plate near the water-blocking column.

[0015] Furthermore, the baffle is conical and gradually bulges outwards in a direction away from the drain outlet.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: By setting the filter screen horizontally, the liquid enters the branch pipe from the inlet pipe, is filtered by the filter screen, and flows out from the outlet pipe. Filtered impurities remain on the outer surface of the filter screen. When the machine is stopped, the separator is vented, and the gas in the outlet pipe is back-blown downwards for self-cleaning. The filter screen is not easily clogged, which extends the cleaning and replacement cycle. Attached Figure Description

[0019] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0020] This utility model provides a multifunctional gas-water separator that can solve the problem in related technologies where filters are easily clogged, shortening the cleaning cycle and requiring periodic removal of the filter for cleaning or replacement of the filter element.

[0021] See Figure 1 and Figure 2 As shown, a multifunctional gas-water separator provided in this embodiment of the present invention includes: a gas-water separator body 1 with a drain port at the bottom; a welded plate-guided cyclone separation structure inside the gas-water separator body 1, which causes the gas entering the separator to flow with the cyclone blades and thus rotate; the rotating airflow causes the liquid water in the airflow to separate along the cylinder wall due to centrifugal force, which is robust, reliable and efficient in separating liquid water; a drain pipe 2 installed at the drain port; the drain pipe 2 includes an inlet pipe 21 at the upper end, an outlet pipe 22 at the lower end and a side branch pipe 23, and the three are interconnected; and a filter screen 3 horizontally installed inside the branch pipe 23, the two ends of the filter screen 3 being closed, and the axis being located between the inlet pipe 21 and the outlet pipe 22. By setting the filter screen 3 horizontally, the liquid enters the branch pipe 23 through the inlet pipe 21, is filtered by the filter screen 3, and flows out through the outlet pipe 22. Impurities in the filter pipeline adhere to the outer surface of the filter element. When the machine stops, the separator is vented, and the gas in the outlet pipeline is back-blown downwards for self-cleaning, causing the filter particles on the filter screen 3 to fall off and achieve the self-cleaning function. This prevents filter impurities from remaining on the inner surface of the filter element, making the filter screen 3 less prone to clogging, extending the cleaning and replacement cycle, reducing vulnerable and consumable parts, integrating components, reducing maintenance time, and lowering maintenance costs.

[0022] See Figure 1 and Figure 2 As shown, in some embodiments, the outer end of the branch pipe 23 is provided with an internal thread, and a threaded cover plate 4 is installed through the internal thread. The filter screen 3 is fixed by the threaded cover plate 4, which makes disassembly and cleaning convenient.

[0023] See Figure 1 and Figure 2 As shown, in some embodiments, the threaded cover plate 4 is held against the outer end of the filter screen 3 by a spring 5, and the filter screen 3 is pressed and fixed by the threaded cover plate 4 and the spring 5 to reduce shaking and facilitate disassembly.

[0024] See Figure 1 and Figure 2 As shown, in some embodiments, the inner end of the filter screen 3 abuts against the inner wall of the drain pipe 2 and is connected to the outlet pipe 22 through a pipe. After being filtered by the filter screen 3, the liquid flows out through the outlet pipe 22, causing impurity particles in the filter pipeline to adhere to the outer surface of the filter element.

[0025] See Figure 1 and Figure 2 As shown, in some embodiments, the filter screen 3 is cylindrical, and there is a space between the outer side and the inner wall of the branch pipe 23, so that the liquid can enter the branch pipe 23 from the inlet pipe 21 and be filtered by the filter screen 3. When the machine is stopped, the impurities on the filter screen can fall to the bottom of the filter screen 3 by gravity and accumulate. The impurities that are self-cleaned by the downward back-blowing of the gas in the outlet pipe can also be collected, which is convenient for cleaning.

[0026] See Figure 1 and Figure 2 As shown, in some embodiments, the diameter of the inlet pipe 21 is smaller than the diameter of the outlet pipe 22. By designing the cylindrical diameters of the inlet pipe 21 and the outlet pipe 22 to be different, the reverse installation of the inlet and outlet pipes is avoided, which would cause the filtered impurities to remain on the inner surface of the filter element.

[0027] See Figure 1 and Figure 2 As shown, in some embodiments, the filter screen 3 is a sintered metal filter screen. The airflow after gas-water separation impacts the filter screen to produce a secondary separation effect of liquid water. The sintered metal filter device can withstand pressure of more than 500 bar, and only needs to be cleaned without replacement, reducing vulnerable and consumable parts.

[0028] See Figure 1 and Figure 3 As shown, in some embodiments, multiple water-blocking columns 6 are arranged parallel to each other on the inner wall of the gas-water separator body 1. The water-blocking columns 6 extend in the vertical direction and can collect the liquid water flowing around the cylinder wall, thus playing a role in water accumulation and diversion and preventing the liquid water from being rolled up by the airflow. The water-blocking columns collect the liquid water flowing around the cylinder wall and prevent the water from being carried upward by the airflow when rotating along the wall, thereby weakening the separation effect.

[0029] See Figure 3 As shown, in some embodiments, a baffle plate 7 is fixed to the lower end of the water-blocking column 6. The baffle plate 7 is fixed around the inner wall of the gas-water separator body 1. A water-guiding groove 71 is provided on the baffle plate 7 near the water-blocking column 6. After the water-blocking column 6 collects liquid water on the cylinder wall, it is guided to the bottom of the baffle plate 7 by the water-guiding groove 71. The baffle plate 7 plays the role of blocking the airflow and further reducing the amount of water that rises with the airflow.

[0030] See Figure 3 As shown, in some embodiments, the baffle 7 is conical and gradually bulges away from the drain outlet, allowing water on the baffle 7 to flow down into the area below the baffle 7, resulting in better drainage.

[0031] See Figure 1 As shown, in some embodiments, the exhaust port of the gas-water separator body 1 is equipped with a fixing plate, which is a customized threaded metal spiral wound gasket, which has both a sealing function and is convenient for disassembly and installation.
