[0002] In industrial production, dehydration of biogas is a common and critical process, and cyclone separators, coalescing filters and corrugated plate demisters are the three most commonly used devices for gas-water separation.

[0003] Among them, the corrugated plate demister has the most excellent gas-water separation effect and a compact structure. At the same time, the air flow pressure loss is minimal when passing through the corrugated plate demister. Therefore, the corrugated plate demister is often the first choice for gas-water separation.

[0004] In actual situations, because biogas contains more impurities, although it has been filtered, it cannot be guaranteed to be completely removed. The corrugated plate has a large contact area with the airflow, which makes it easy for scale to accumulate on the corrugated plate, causing plate surface pollution and thus affecting the separation efficiency. Therefore, regular cleaning is required, and some stubborn scale even needs to be removed by disassembly and flushing, so it is inconvenient to maintain. Therefore, a comprehensive gas-water separation device suitable for biogas dehydration is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a comprehensive gas-water separation device suitable for biogas dehydration provided by an embodiment of the present invention includes an air inlet chamber 1, and also includes:

[0034] A separation chamber 2, wherein the separation chamber 2 is located at the top of the air inlet chamber 1, and the two are internally connected, the separation chamber 2 comprises an external box body 201, a transverse plate body 202 is arranged in the external box body 201, a rectangular mounting position 203 is provided on the plate body 202, a plurality of corrugated plates 204 are fixedly arranged in the rectangular mounting position 203, a predetermined spacing is provided between the plurality of corrugated plates 204, and the corrugated plates 204 themselves are arranged along the length direction of the plate body 202, a plurality of plate-shaped brackets 205 are arranged in the rectangular mounting position 203 on the plate body 202, the plate-shaped brackets 205 are arranged at intervals along the length direction of the plate body 202, the plate-shaped brackets 205 are used to limit the corrugated plates 204, and the plate-shaped brackets 205 can move laterally on the corrugated plates 204, the plate body 202 is a hollow structure, and driving components 3 are arranged on both sides of the plate body 202, and the driving components 3 are used to drive one or more plate-shaped brackets 205 to move back and forth;

[0035] The collecting chamber 4 is located at the top of the separation chamber 2. The collecting chamber 4 includes a conical box body, and a gas collecting pipe 401 is fixedly connected to the top of the conical box body;

[0036] The bottom of the air inlet chamber 1 is fixedly connected with a liquid collecting pipe 5 , on which a drain valve is arranged. The liquid collecting pipe 5 is used to collect liquid drops falling from the corrugated plate 204 .

[0037] In one embodiment of the present invention, the device conveys the airflow upward through the air inlet chamber 1, and the airflow will be separated from the water after passing through the corrugated plate 204 in the separation chamber 2, and the dehydrated biogas will be discharged from the gas collection pipe 401 in the collection chamber 4, and the droplets separated by the corrugated plate 204 will gather at the bottom of the air inlet chamber 1 and be discharged from the liquid collection pipe 5. When the corrugated plate 204 needs to be cleaned, the plate-shaped bracket 205 is driven to reciprocate by the driving component 3 according to the part of the corrugated plate 204 that needs to be cleaned. The feature of the present invention is that the plate-shaped bracket 205 is not only used to limit the corrugated plate 204, but the plate-shaped bracket 205 can also move horizontally to clean the plate surface of the corrugated plate 204, so that the present device has a long-lasting and efficient air-water separation effect. In summary, the present invention can conveniently clean the structure for separating air and water on the basis of achieving efficient air-water separation, and the actual use effect is remarkable.

[0038] It should be noted that if Figure 7As shown, the plate-shaped bracket 205 is provided with a plurality of special-shaped grooves 6 spaced apart along its length direction, the bottom of the special-shaped grooves 6 is an open structure, and the shape of the special-shaped grooves 6 is consistent with the cross-sectional shape of the corrugated plate 204, and the parts of the special-shaped grooves 6 in contact with the corrugated plate 204 are provided with strip pads of flexible material. When the plate surface of the corrugated plate 204 is in a clean state, the attached liquid will fall naturally, and when the plate surface is fouled, it will first affect the separation effect when the airflow hits it, and the droplets will also be difficult to fall due to the increased surface tension, and even the problem of secondary entrainment of the upward airflow will occur. The plate-shaped bracket 205 in the present invention adopts a special structure. First, the special-shaped grooves 6 can play a good limiting role on the corrugated plate 204, and when the plate-shaped bracket 205 moves back and forth, the strip pads will slide over the plate surface of the corrugated plate 204, and then combined with the fouled plate surface with liquid attached to it, the plate surface will be smooth and smooth. The moving strip pad cooperates with the corrugated plate 204 to which the droplets are attached to achieve cleaning. The strip pad can be made of rubber and can also protect the surface of the corrugated plate 204. In addition, the reciprocating stroke of the plate-shaped bracket 205 needs to be limited. The length of the rectangular through groove 7 is equal to the length of the rectangular mounting position 203, and the two ends of the rectangular through groove 7 are flush with the two sides of the rectangular mounting position 203, ensuring that all the plate-shaped brackets 205 can reciprocate to cover the entire surface of the corrugated plate 204. In addition, a liquid level sensor is installed in the water accumulation area at the bottom of the air inlet chamber 1 to monitor the liquid level. A programmable logic controller (PLC) is used as a controller to receive the signal of the liquid level sensor and control the opening and closing of the drain valve according to the preset liquid level height value to ensure that the internal liquid level is always maintained within the normal range to prevent excessive water accumulation from affecting the separation effect.

[0039] like Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, rectangular through grooves 7 are opened on both sides of the plate body 202 along its length direction, the rectangular through grooves 7 are located on both sides of the rectangular mounting position 203, and the rectangular through grooves 7 are arranged toward the collection chamber 4 at the top; the tops of the two ends of the plate-shaped bracket 205 are fixedly connected with side frames 8, and the other end of the side frame 8 is fixedly connected with a column 9 slidably arranged in the rectangular through groove 7, and the column 9 is used to cooperate with the corresponding driving assembly 3, so that the driving assemblies 3 on both sides drive the columns 9, side frames 8 and plate-shaped bracket 205 on both sides to move.

[0040] In one case of the present embodiment, the driving assembly 3 includes driving members 301 arranged at both ends, and the output ends of the two driving members 301 are connected by a screw rod 302, and the screw rod 302 is matched with a moving block 303 with the same number and corresponding position as the column 9. The driving member 301 is used to drive the screw rod 302 to rotate, and the rotation direction of the screw rod 302 can be adjusted. When the driving member 301 drives the screw rod 302 to rotate, the moving block 303 can move along the direction of the rectangular through groove 7; a connecting assembly is fixedly arranged on the top of the moving block 303, and the connecting assembly is used to connect or disconnect the moving block 303 with the corresponding column 9. The driving member 301 can be in the form of an electric motor, and of course it can also be in the form of a hydraulic motor, as long as it can drive the screw rod 302 to rotate. In order to facilitate the description of the cleaning process of the corrugated plate 204, the present embodiment also provides a method for controlling the movement of the plate-shaped bracket 205, such as Figure 8 As shown, the specific steps include:

[0041] S100, obtaining pressure data from a plurality of pressure sensors, wherein the pressure sensors are differential pressure sensors disposed above the corrugated plate 204, and a plurality of differential pressure sensors are evenly distributed, and can collect airflow pressure in each area;

[0042] S200, synchronizing all pressure data through a data acquisition system to determine the synchronization of each pressure data;

[0043] S300, selecting the pressure at the center position as a reference and recording the relative pressures at other positions;

[0044] S400, obtaining the relative airflow velocity at each position according to the relative pressure and using the Bernoulli equation;

[0045] S500, preparing an airflow distribution map based on the above results, and analyzing the abnormal area with abnormal airflow velocity according to the airflow distribution map;

[0046] S600, starting the corresponding connection assembly according to the abnormal area, so that the rotation of the screw rod 302 can drive the plate-shaped bracket 205 to move back and forth.

[0047] It should be noted that it is feasible to measure the air flow velocity by pressure, because the Bernoulli equation describes the relationship between the pressure, velocity and height of the fluid at different positions. In this embodiment, the height data is consistent, and the pressure data can be obtained by a differential pressure sensor. Therefore, the relative air flow velocity relative to the center position can be calculated. When a certain part of the corrugated plate 204 is fouled, the air flow in this area must be faster or slower than other positions. This method can be used to quickly obtain the fouled area of ​​the corrugated plate 204, so as to facilitate the control of the corresponding plate-shaped bracket 205 for cleaning.

[0048] like Figure 6 As shown, as a preferred embodiment of the present invention, the connecting assembly includes an annular electromagnet 10 arranged on the top of the moving block 303, and a push pin 11 that can move in the vertical direction is arranged in the column 9 slidably arranged in the rectangular through groove 7, and a circular hole 12 corresponding to the position of the push pin 11 is opened at the bottom of the column 9, and an elastic reset member 13 is arranged outside the push pin 11. When there is no external force acting on the push pin 11, the elastic reset member 13 is used to keep the push pin 11 in the column 9. The elastic reset member 13 can be a spring, and of course it can also be in the form of an air cushion. When the annular electromagnet 10 is energized, the push pin 11 moves to the inside of the annular electromagnet 10 through the circular hole 12.

[0049] In one case of the present embodiment, after the area to be cleaned is determined by the above method, the corresponding annular electromagnet 10 will be selected to be started. The annular electromagnets 10 all have representative numbers (the corresponding annular electromagnets 10 can be selected to be started according to needs), and the push pins 11 are generally made of metal iron. The push pins 11 will move down into the interior under the adsorption action of the annular electromagnet 10, so that the column 9 is connected to the moving block 303. When the screw 302 rotates, the moving block 303 will push the column 9 to move, thereby moving the plate-shaped brackets 205 on the corrugated plate 204. The plate-shaped brackets 205 are evenly distributed, and the movement of adjacent plate-shaped brackets 205 will not interfere with each other.

[0050] like Figure 4 and Figure 6 As shown, as a preferred embodiment of the present invention, vertically arranged slide grooves 14 are opened on both sides of the column 9, and a cross frame 15 with two ends slidably connected to the slide groove 14 is fixedly connected to the top of the top pin 11, and a transversely arranged closing strip 16 is fixedly connected to both ends of the cross frame 15, and the width of the closing strip 16 is consistent with the width of the rectangular through groove 7; when the annular electromagnet 10 is not energized, the elastic reset member 13 is in the initial state, and the cross frame 15 is located at the top of the slide groove 14, and the closing strip 16 is located in the rectangular through groove 7; when all the closing strips 16 are located in the rectangular through groove 7, the rectangular through groove 7 is closed as a whole.

[0051] In one case of the present embodiment, because it is used in the field of gas-water separation of biogas, although the fixed particles in the airflow will be removed, it is not thorough enough. If the rectangular through groove 7 is not closed, dust or dirt will inevitably enter the rectangular through groove 7 when the device is working, which will affect the internal mechanical structure and of course affect the movement of the column 9. However, the rectangular through groove 7 cannot be closed. If it is closed, the feature that the column 9 can move will not exist. Therefore, the present embodiment uses the top pin 11 to move up and down. The characteristic is that when the top pin 11 moves downward, the closing strips 16 on both sides can move downward synchronously, thereby disengaging from the rectangular through groove 7, so that the lateral movement of the column 9 will not be interfered, and after the plate-shaped bracket 205 is reset, the elastic reset member 13 will reset the cross frame 15, so that the closing strip 16 is reset to the rectangular through groove 7. In addition, due to the existence of the closing strip 16, the lateral movement of the column 9 can be limited in range, that is, under the premise that the width of the column 9 is equal to the width of the plate-shaped bracket 205, the closing strip 16 can ensure that the movement range of the column 9 is fixed.

[0052] like Figure 1 As shown in the figure, as a preferred embodiment of the present invention, the air inlet chamber 1 is provided with an annular tube 17 outside, and the annular tube 17 is connected to the air inlet chamber 1 through an evenly distributed air inlet pipe 18, and a flow control valve 19 is provided on the air inlet pipe 18.

[0053] In one case of this embodiment, the annular tube 17 is connected to the cyclone separator 21 through a straight tube 20, so that when air is inletted, the cyclone separator 21 can first separate larger particles or droplets, and the cyclone separator 21 can cooperate with the corrugated plate 204 to separate the airflow into gas and water in batches, further ensuring the separation effect. The cyclone separator 21 made of stainless steel is designed with a special spiral guide channel inside. When the biogas enters the cyclone separator 21 at a high speed along the tangential direction, under the action of centrifugal force, the droplets in the biogas are thrown to the wall of the device, forming a liquid film and flowing to the bottom along the wall. In addition, the role of the annular tube 17 and the air inlet pipe 18 is to enable uniform air intake and ensure the uniformity of the airflow passing through the corrugated plate 204, and the flow control valve 19 can more accurately control the intake volume.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0055] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
