Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology for ceramic membrane equipment, specifically to a residual pressure noise reduction and efficiency improvement device for ceramic membrane equipment. Background Technology

[0002] In the field of wastewater treatment, ceramic membranes can efficiently remove suspended solids, colloids, microorganisms and organic matter in wastewater. They are especially suitable for the deep treatment and reuse of high-concentration industrial wastewater (such as coal chemical wastewater and pharmaceutical wastewater), helping enterprises to meet emission standards.

[0003] In order to reduce the explosion noise of the released residual pressure during the operation of ceramic membrane equipment used in related technologies, a silencer is usually connected to the end of the residual pressure release pipeline to reduce noise through the sound absorption of the porous structure.

[0004] However, during use, the reduction in noise levels is very limited, resulting in an unsatisfactory effect of residual pressure noise reduction. Due to the operating characteristics of ceramic membrane equipment, frequent residual pressure release is required, which still causes significant operational disruption for on-site operators. To address these issues, a residual pressure noise reduction and efficiency improvement device for ceramic membrane equipment is proposed. Utility Model Content

[0005] In view of this, the present invention provides a residual pressure noise reduction and efficiency improvement device for ceramic membrane equipment. The present invention keeps the pressure-distributing cylinder and the noise reduction device below the water level. The pressurized gas is discharged into the pressure-distributing cylinder through the residual pressure exhaust pipe. The pressure is then guided to the first pressure relief pipes on both sides by the pressure-distributing cylinder. By extending the first pressure relief pipes into the noise reduction cylinder inside the noise reduction device, the pressure impact is reduced by the water body, thereby canceling the noise and completing the pressure relief and noise reduction operation. This effectively reduces the decibel level of the noise and can be remotely coordinated with ceramic membrane equipment for frequent operation, providing a better working environment for the staff.

[0006] To solve the above-mentioned technical problems, this utility model provides a residual pressure noise reduction and efficiency improvement device for ceramic membrane equipment, including a residual pressure exhaust pipe, a first electric valve installed on the residual pressure exhaust pipe, a pressure dividing cylinder installed at the outlet end of the residual pressure exhaust pipe, a bypass pipe installed between the pressure dividing cylinder and the first electric valve, the bypass pipe being connected to the residual pressure exhaust pipe, a first pressure relief pipe installed on both sides of the pressure dividing cylinder, and a noise reduction device connected to the outlet end of each first pressure relief pipe.

[0007] Each noise reduction device includes a noise reduction cylinder, which is used to install a water inlet connector and place a first pressure relief pipe. Each end of the noise reduction cylinder near the pressure dividing cylinder is provided with a water inlet connector, which is used to fill the noise reduction cylinder with water. The first pressure relief pipe on the same side passes through the water inlet connector and enters the noise reduction cylinder. Each section of the first pressure relief pipe entering the noise reduction cylinder is provided with multiple vents, which are used to discharge the residual pressure in the first pressure relief pipe into the water-filled noise reduction cylinder.

[0008] The surface of the first pressure relief pipe section entering the noise reduction cylinder is provided with multiple positioning rods. The positioning rods are used to fix the first pressure relief pipe, thereby connecting the first pressure relief pipe to the inner wall of the noise reduction cylinder. The positioning rods are arranged at intervals with the exhaust port.

[0009] One end of the positioning rod is arc-shaped and welded to the first pressure relief pipe, while the other end of the positioning rod is welded to the inner wall of the noise reduction cylinder.

[0010] The surface of the noise reduction cylinder is equipped with multiple filter grids. The filter grids are used to disperse the sound waves caused by the pressure in the first pressure relief pipe. The coaxial filter grids form a circle, and the filter grids and positioning rods are arranged at intervals.

[0011] The first pressure relief pipe has a first flange on the section that passes through the water inlet connector. The first flange is used to facilitate the maintenance of the part where the first pressure relief pipe is connected to the noise reduction cylinder. A second flange is provided between the first flange and the pressure dividing cylinder. The second flange is also used to facilitate the maintenance of the part where the first pressure relief pipe is connected to the pressure dividing cylinder.

[0012] An air inlet connector is centrally located at the top of the pressure dividing cylinder. The air inlet connector is used to connect the pressure dividing cylinder to the residual pressure exhaust pipe. A third flange is provided at the air inlet end of the air inlet connector. The third flange facilitates the maintenance of the part connecting the residual pressure exhaust pipe and the pressure dividing cylinder. The third flange is connected to the air outlet end of the residual pressure exhaust pipe.

[0013] A second electric valve is installed at the outlet of the bypass pipe, which is used to control the opening and closing of the bypass pipe.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. By keeping the pressure-distributing cylinder and noise reduction device below the water level, pressurized gas is discharged into the pressure-distributing cylinder through the residual pressure exhaust pipe. The pressure is then guided to the first pressure relief pipes on both sides. By extending the first pressure relief pipe into the noise reduction cylinder inside the noise reduction device, the pressure impact is reduced by the water body, thereby canceling out the noise and completing the pressure relief and noise reduction operation. This effectively reduces the decibel level of the noise and can be remotely coordinated with ceramic membrane equipment for frequent operation, providing a better working environment for the staff.

[0016] 2. The positioning rod is used to fix the first pressure relief pipe, thereby connecting the first pressure relief pipe to the inner wall of the noise reduction cylinder, so that the part of the first pressure relief pipe that extends into the noise reduction cylinder is supported.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figure 1-4As shown: This embodiment provides a residual pressure noise reduction and efficiency improvement device for ceramic membrane equipment, including a residual pressure exhaust pipe 100. The residual pressure exhaust pipe 100 is used to discharge pressurized gas that needs to be depressurized and reduced for noise in the ceramic membrane equipment. A first electric valve 101 is installed on the residual pressure exhaust pipe 100. The first electric valve 101 is fixed to the residual pressure exhaust pipe 100 by a flange and bolts. The first electric valve 101 is used to electrically and remotely open and close the residual pressure exhaust pipe 100 to release gas to the pressure dividing cylinder 200. A pressure dividing cylinder 200 is installed at the outlet end of the residual pressure exhaust pipe 100. The pressure dividing cylinder 200 is used to split the gas in the residual pressure exhaust pipe 100 into two parts. A bypass pipe 201 is provided between the pressure dividing cylinder 200 and the first electric valve 101. The bypass pipe 201 is welded to the residual pressure exhaust pipe 100. The bypass pipe 201 is used to connect the noise reduction cylinder 301 and the residual pressure exhaust pipe 100. Through the principle of the connecting pipe, the free air in the pressure reducing cylinder 200 is discharged from the bypass pipe 201. The bypass pipe 201 is connected to the residual pressure exhaust pipe 100. A first pressure relief pipe 202 is provided on both sides of the pressure reducing cylinder 200. The pressure reducing cylinder 200 and the first pressure relief pipe 202 are welded together. The first pressure relief pipe 202 is used to guide the pressurized gas in the pressure reducing cylinder 200 to the noise reducing cylinder 301 in the noise reducing device 300. A noise reducing device 300 is connected to the outlet end of each first pressure relief pipe 202. The noise reducing device 300 is used to relieve the pressure of the gas discharged from the first pressure relief pipe 202. The pressure reducing cylinder 200 and the noise reducing device 300 need to be located below the water surface and completely immersed in the water.

[0025] During use, by keeping the pressure-distributing cylinder 200 and the noise reduction device 300 below the water level, the pressurized gas is discharged into the pressure-distributing cylinder 200 through the residual pressure exhaust pipe 100. The pressure is then guided to the first pressure relief pipes 202 on both sides through the pressure-distributing cylinder 200. By extending the first pressure relief pipes 202 into the noise reduction cylinder 301 inside the noise reduction device 300, the pressure impact is reduced by the water body, thereby canceling out the noise and completing the pressure relief and noise reduction operation. This effectively reduces the decibel level of the noise and can be remotely coordinated with ceramic membrane equipment for frequent operation, providing a better working environment for the staff.

[0026] This embodiment provides a residual pressure noise reduction and efficiency improvement device for ceramic membrane equipment.

[0027] like Figure 1 , 2As shown in Figures 3 and 4: Each noise reduction device 300 includes a noise reduction cylinder 301. The noise reduction cylinder 301 is used to install a water inlet connector 302 and to place a first pressure relief pipe 202. A water inlet connector 302 is provided at one end of the noise reduction cylinder 301 near the pressure dividing cylinder 200. The water inlet connector 302 is welded to the noise reduction cylinder 301. The water inlet connector 302 is used to fill the noise reduction cylinder 301 with water. The first pressure relief pipe 202 on the same side passes through the water inlet connector 302 and enters the noise reduction cylinder 301. Each section of the first pressure relief pipe 202 entering the noise reduction cylinder 301 is provided with multiple exhaust ports 303. The exhaust ports 303 symmetrically pass through the first pressure relief pipe 202. The exhaust ports 303 are used to discharge the residual pressure in the first pressure relief pipe 202 into the water-filled noise reduction cylinder 301.

[0028] Its effect is as follows: the noise reduction tube 301 is used to install the water inlet connector 302 and place the first pressure relief pipe 202. The water inlet connector 302 is used to fill the noise reduction tube 301 with water, and the exhaust port 303 is used to discharge the residual pressure in the first pressure relief pipe 202 into the water-filled noise reduction tube 301.

[0029] like Figure 2 , 3 As shown: The surface of the pipe section where the first pressure relief pipe 202 enters the noise reduction cylinder 301 is provided with multiple positioning rods 304. The positioning rods 304 can be cylindrical rods. The positioning rods 304 are used to fix the first pressure relief pipe 202, thereby connecting the first pressure relief pipe 202 to the inner wall of the noise reduction cylinder 301. The positioning rods 304 and the exhaust port 303 are arranged at intervals. One end of the positioning rod 304 is arc-shaped and welded to the first pressure relief pipe 202, and the other end of the positioning rod 304 is welded to the inner wall of the noise reduction cylinder 301.

[0030] Its effect is as follows: the positioning rod 304 is used to fix the first pressure relief pipe 202, thereby connecting the first pressure relief pipe 202 to the inner wall of the noise reduction cylinder 301.

[0031] like Figure 1 , 2 As shown in Figure 3: Multiple filter grids 305 are provided on the surface of the noise reduction cylinder 301. The filter grids 305 are welded to the cylinder wall of the noise reduction cylinder 301. The filter grids 305 are used to disperse the sound waves caused by the pressure in the first pressure relief pipe 202. The coaxial filter grids 305 form a circle. The filter grids 305 and the positioning rods 304 are arranged at intervals.

[0032] Its effect is as follows: the filter grid 305 is used to disperse the sound waves caused by the pressure in the first pressure relief pipe 202, reduce the density of the sound waves discharged to the water surface, and thus improve the noise reduction effect.

[0033] like Figure 1 , 2As shown in Figures 3 and 4: The first pressure relief pipe 202 has a first flange 203 on a section passing through the inlet connector 302. The first flange 203 is fixed by two flanges connected by bolts and gaskets. The two flanges on the first flange 203 are welded to the first pressure relief pipe 202 located above the inlet connector 302. The first flange 203 is used to facilitate maintenance of the connection between the first pressure relief pipe 202 and the noise reduction cylinder 301. A second flange 204 is provided between the first flange 203 and the pressure reducing cylinder 200. The second flange 204 is fixed by two flanges connected by bolts and gaskets. The two flanges on the second flange 204 are welded to the first pressure relief pipe 202 located on the outlet side of the pressure reducing cylinder 200. The second flange 204 is used to facilitate maintenance of the connection between the first pressure relief pipe 202 and the pressure reducing cylinder 201. At the 00 connection point, an air inlet connector 102 is centrally located at the upper end of the pressure-distributing cylinder 200. The air inlet connector 102 is welded to the pressure-distributing cylinder 200, forming a shape similar to a tee after welding. The air inlet connector 102 is used to connect the pressure-distributing cylinder 200 to the residual pressure exhaust pipe 100. A third flange 205 is provided at the air inlet end of the air inlet connector 102. The third flange 205 is fixed by two flanges connected by bolts and gaskets. One side of the two flanges on the third flange 205 is welded to the air outlet end of the residual pressure exhaust pipe 100, and the other side is welded to the air inlet connector 102. The third flange 205 facilitates the maintenance of the connection between the residual pressure exhaust pipe and the pressure-distributing cylinder 200. The third flange 205 is connected to the air outlet end of the residual pressure exhaust pipe 100.

[0034] Its effects are as follows: the first flange 203 is used to facilitate the maintenance of the part where the first pressure relief pipe 202 is connected to the noise reduction cylinder 301; the second flange 204 is used to facilitate the maintenance of the part where the first pressure relief pipe 202 is connected to the pressure dividing cylinder 200; and the third flange 205 is used to facilitate the maintenance of the part where the residual pressure exhaust pipe is connected to the pressure dividing cylinder 200.

[0035] like Figure 1 , 2 As shown: A second electric valve 206 is provided at the air outlet of the bypass pipe 201. The bypass pipe 201 and the second electric valve 206 need to be above the water surface. The bypass pipe 201 and the second electric valve 206 are connected and fixed by a flange. The second electric valve 206 is used to control the opening and closing of the bypass pipe 201.

[0036] Its effect is as follows: through the bypass pipe 201 and the water inlet connector 302, the residual pressure exhaust pipe 100, the pressure dividing cylinder 200 and the noise reduction device 300 can form a connecting device, and then automatically replenish water through the principle of the connecting device without the need for additional power.

[0037] Working principle: By keeping the pressure-distributing cylinder 200 and the noise reduction device 300 below the water level, the first electric valve 101 is opened, allowing pressurized gas to be discharged from the pressure-distributing cylinder 200 through the residual pressure exhaust pipe 100. The pressure is then guided through the pressure-distributing cylinder 200 to the first pressure relief pipes 202 on both sides. The first pressure relief pipes 202 are then inserted into the noise reduction cylinder 301 inside the noise reduction device 300, and the pressurized gas in the residual pressure exhaust pipe 100 is discharged into the water through the exhaust port 303. This reduces the pressure impact through the water body, thereby canceling out the noise and completing the pressure relief and noise reduction operation. The entire pressure relief process can be remotely controlled by PLC, effectively reducing the decibel level of noise. It can be remotely coordinated with ceramic membrane equipment for frequent operations, providing a better working environment for the staff.

[0038] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
