Description

Technical fields:

[0001] This utility model relates to the field of exhaust gas treatment technology, specifically to a large-scale venting gas treatment mechanism. Background technology:

[0002] The large-scale venting at the end of the gas system is achieved by replacing the internal components of the valve actuator, removing the original switch control module, installing an analog control module, and adding a program in the DCS. This allows the valve to automatically adjust its opening based on a pre-set pressure range, reducing human error and enabling the venting of gas. The gas venting process carries a large amount of heat, which needs to be collected by a gas treatment device.

[0003] The existing gas treatment device mainly consists of two chambers fixedly connected by multiple heat exchange tubes. The multiple heat exchange tubes run through the gas pipe. When heat exchange is required, an external water source is injected into the chamber connected to it by a water pump, and then enters the other chamber through multiple heat exchange tubes. The flue gas transfers heat to the surface of the heat exchange tubes and then to the water inside the heat exchange tubes. Finally, it is discharged from the drain pipe to the appropriate equipment to collect the heat. The fixed connection between the chamber and the heat exchange tubes prevents the heat exchange tubes from rotating, resulting in a constant heating area of ​​the heat exchange tubes and poor heat exchange effect between the heat exchange tubes and the gas. Utility Model Content:

[0004] Therefore, the purpose of this utility model is to provide a large-scale venting gas treatment mechanism to overcome the problems of existing gas treatment mechanisms, which mainly consist of two chambers fixedly connected by multiple heat exchange tubes. These heat exchange tubes run through the gas pipe. When heat exchange is required, an external water source is injected into the chamber connected to it by a water pump, and then enters the other chamber through multiple heat exchange tubes. The flue gas transfers heat to the surface of the heat exchange tubes and then along the heat exchange tubes to the water inside. Finally, it is discharged from the drain pipe into a suitable device to collect the heat. The fixed connection between the chamber and the heat exchange tubes prevents the heat exchange tubes from rotating, resulting in a constant heating area of ​​the heat exchange tubes and poor heat exchange effect between the heat exchange tubes and the gas.

[0005] This utility model is implemented by the following technical solution:

[0006] A large-scale venting gas treatment mechanism includes a gas pipe with a solenoid valve connected to its outer wall. Two cavities are located on the side wall of the gas pipe, which is positioned between them. The two cavities are fixedly connected at both ends by a support rod, the side wall of which is fixedly connected to the outer wall of the gas pipe. A water pump is fixedly connected to the side wall of one cavity, and a drain pipe is fixedly connected to the side wall of the other cavity. The two cavities are connected by multiple heat exchange tubes, both ends of which are inserted into and rotatably connected to the corresponding cavity. The heat exchange tubes penetrate the gas pipe. The gas pipe is rotatably connected to the heat exchange tube. The outer wall of the heat exchange tube is fitted with multiple sealing rings. Some of the sealing rings are located inside the cavity, and the other part of the sealing rings are located on the outer wall of the gas pipe. The side wall of the sealing ring inside the cavity is in contact with the inner wall of the cavity and is fixedly connected to the heat exchange tube. The sealing ring on the side wall of the gas pipe is fixedly connected to the side wall of the gas pipe and is rotatably connected to the heat exchange tube. An assembly for driving the heat exchange tube to rotate is fixedly connected to the side wall of one of the cavities. The output end of the assembly for driving the heat exchange tube to rotate is fixedly connected to the heat exchange tube.

[0007] Preferably, the heat exchange tube inside the gas pipe has an arc-shaped cross-section.

[0008] Preferably, the arc surfaces of two adjacent heat exchange tubes are not on the same plane.

[0009] Preferably, the heat exchange tube is inclined and the inclination direction is upward along the direction close to the drain pipe.

[0010] Preferably, the component that drives the heat exchange tube to rotate includes a motor and multiple toothed rings. The toothed rings are fixedly sleeved on the heat exchange tube and located outside the gas pipe. Adjacent toothed rings mesh with each other. The motor is fixed to the side wall of the cavity.

[0011] Preferably, multiple heat-conducting perforated plates are fixedly connected to the inner top and inner bottom surfaces of the heat exchange tube, and adjacent heat-conducting perforated plates are staggered.

[0012] Advantages of this invention: Multiple heat exchange tubes are rotatably connected between the two cavities.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0021] 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.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figures 1-3 As shown, this utility model provides the following technical solution: a large-scale venting gas treatment mechanism, including a gas pipe 1, an electromagnetic valve 2 connected to the outer wall of the gas pipe 1, two cavities 3 provided on the side wall of the gas pipe 1, the gas pipe 1 being positioned between the two cavities 3, the two ends of the two cavities 3 being fixedly connected by a support rod 4, the side wall of the support rod 4 being fixedly connected to the outer wall of the gas pipe 1, one cavity 3 being fixedly connected to a water pump 11 on its side wall, and the other cavity 3 being fixedly connected to a drain pipe 12 on its side wall, the two cavities 3 being connected by multiple heat exchange pipes 5, both ends of the heat exchange pipes 5 being inserted into the corresponding cavity 3 and rotatably connected to it, the heat exchange... The heat pipe 5 passes through the gas pipe 1 and is rotatably connected to it. The outer wall of the heat pipe 5 is fitted with multiple sealing rings 7. Some of the sealing rings 7 are located inside the cavity 3, and the other part of the sealing rings 7 are located on the outer wall of the gas pipe 1. The side wall of the sealing ring 7 located inside the cavity 3 is in contact with the inner wall of the cavity 3 and is fixedly connected to the heat pipe 5. The sealing ring 7 located on the side wall of the gas pipe 1 is fixedly connected to the side wall of the gas pipe 1 and is rotatably connected to the heat pipe 5. An assembly for driving the heat pipe 5 to rotate is fixedly connected to the side wall of one of the cavities 3. The output end of the assembly for driving the heat pipe 5 to rotate is fixedly connected to the heat pipe 5.

[0023] Please combine Figure 1 As shown, when the gas pipe 1 opens the solenoid valve 2 for large-scale venting, the solenoid valve 2 can adjust the amount of gas discharged from the gas pipe 1, thereby improving the stability of the gas discharge pressure. When the gas contains a large amount of heat and needs heat exchange, the controller starts the water pump 11 and the component that drives the heat exchange tube 5 to rotate. The gas is gradually discharged from the bottom of the gas pipe 1 upwards, passing through the bottom surface of the heat exchange tube 5 and transferring heat to the surface of the heat exchange tube 5. The water pump 11 transports external water to the cavity 3 connected to it and then to the heat exchange tube 5. The water absorbs the heat from the surface of the heat exchange tube 5, and the water that has absorbed the heat then enters another cavity 3 along the heat exchange tube 5, and then is discharged to other equipment along the drain pipe 12. The component that drives the heat exchange tube 5 to rotate causes the heat exchange tube 5 to rotate, causing the bottom surface of the heat exchange tube 5 to rotate, so that the bottom surface of the heat exchange tube 5 is constantly changing, thereby increasing the contact area between the heat exchange tube 5 and the gas and improving the heat exchange effect of the gas.

[0024] The heat exchange tube 5 located inside the gas pipe 1 has an arc-shaped cross-section, which increases the area of ​​the heat exchange tube 5 inside the gas pipe 1, thereby increasing the heat exchange area of ​​the heat exchange tube 5 and improving the heat exchange effect.

[0025] The arc surfaces of two adjacent heat exchange tubes 5 are not on the same plane, which can reduce the distance between the two adjacent heat exchange tubes 5, thereby increasing the number of heat exchange tubes 5 and improving the heat exchange effect.

[0026] The heat exchange tube 5 is inclined and the inclination direction is upward along the direction close to the drain pipe 12, so that the water gradually flows along the heat exchange tube 5. The inclination of the heat exchange tube 5 causes the water to move upward gradually, providing resistance to the movement of the water, reducing the flow speed of the water, prolonging the residence time of the water in the heat exchange tube 5, and improving the heat exchange effect.

[0027] The components that drive the heat exchange tube 5 to rotate include a motor 9 and multiple toothed rings 8. The toothed rings 8 are fixedly sleeved on the heat exchange tube 5 and located outside the gas pipe 1. Adjacent toothed rings 8 mesh with each other. The motor 9 is fixed to the side wall of the cavity 3. A gear 10 is fixedly connected to the output end of the motor 9, and the gear 10 meshes with one of the toothed rings 8.

[0028] When the heat exchange tube 5 needs to be rotated, the controller is operated to start the motor 9. The output end of the motor 9 drives the gear 10 to rotate, the gear 10 drives the gear ring 8 that meshes with it to rotate, the gear ring 8 drives the adjacent gear ring 8 to rotate, and the gear ring 8 drives the heat exchange tube 5 to rotate, so that the heat exchange tube 5 changes the contact surface with the gas and improves the heat exchange effect.

[0029] Multiple heat-conducting perforated plates 6 are fixedly connected to the inner top and bottom surfaces of the heat exchange tube 5. The heat-conducting perforated plates 6 are staggered between adjacent pairs. The arrangement of multiple heat-conducting perforated plates 6 acts as a barrier to water, slowing down the flow rate of water, prolonging the residence time of water in the heat exchange tube 5, and improving the heat exchange effect. At the same time, the heat exchange tube 5 can transfer heat to the heat-conducting perforated plates 6, and the heat from the heat-conducting perforated plates 6 can be transferred to the water.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
