Description

Technical Field

[0001] This utility model relates to the field of pulse dust collector technology, and in particular to a tail gas filtration mechanism for a high temperature and high humidity pulse dust collector. Background Technology

[0002] High-temperature and high-humidity pulse jet dust collectors are industrial dust removal devices specifically designed for handling high-temperature (typically >200℃) and high-humidity dust-laden gases. Their core principle is to achieve efficient dust removal of filter media (filter bags or cartridges) through pulse jet cleaning technology. Simultaneously, they must cope with the special challenges posed by extreme operating conditions. They are mainly used in industries such as textile printing and dyeing, steel and power, chemical and pharmaceutical, and papermaking and food processing. Pre-filtration of the exhaust gas is required when using high-temperature and high-humidity pulse jet dust collectors.

[0003] Existing high-temperature and high-humidity pulse dust collectors do not have an effective exhaust gas filtration mechanism during use. They cannot pre-filter the exhaust gas when it is input, thus failing to remove large particulate impurities carried in the exhaust gas. This inability to remove impurities leads to their entry into the internal structure, increasing wear, reducing exhaust gas treatment efficiency, and shortening service life. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tail gas filtration mechanism for a high-temperature and high-humidity pulse dust collector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tail gas filtration mechanism for a high-temperature and high-humidity pulse dust collector includes a filter assembly. The filter assembly comprises a main body of the high-temperature and high-humidity pulse dust collector. A cooling chamber is connected to one side of the main body, and a filter chamber is connected to one end of the cooling chamber. A cooling and dehumidification assembly for cooling and dehumidification is installed on one side of the cooling chamber. Fixed supports are symmetrically arranged on the inner walls of both sides of the filter chamber. A spring is installed on one side of each fixed support, and a filter plate is installed at the other end of the spring. The size of the filter plate is adapted to the filter chamber, and the filter plate has several sets of sieve holes arranged sequentially. The fixed supports have guide holes for... A guide rod is slidably mounted on the guide hole, with one end of the guide rod fixed to the filter plate. A fixed seat is installed on the inner wall of one side of the filter chamber, and a drive motor is installed on one side of the fixed seat. The output end of the drive motor is connected to a connecting shaft, one end of which is rotatable and passes through the fixed seat. An adjustment frame is installed on the connecting shaft, and a vibration motor is installed on one side of the adjustment frame. A protective pad is installed at one end of the vibration motor, and the corners of the protective pad are rounded. A filtration assembly for removing impurities is installed on one side of the filter chamber, and a drainage assembly for removing condensate is installed on one side of the cooling chamber. An air supply pipe is connected to one side of the filter chamber.

[0006] As a further embodiment of this utility model: the impurity removal component includes a mounting base, which is installed at the bottom of the filter chamber. The bottom of the filter chamber has a discharge port, the position and size of which are adapted to the filter plate. A sealing baffle is rotatably installed on the mounting base, and the size and position of the sealing baffle are adapted to the discharge port.

[0007] As a further embodiment of this utility model: the cooling and dehumidification assembly includes a delivery pump, which is installed on the top of the cooling chamber. A condenser is provided on one side of the delivery pump. One end of the delivery pump is connected to a delivery pipe, and the other end of the delivery pipe is connected to the condenser. A cooling pipe is provided inside the cooling chamber, with both ends of the cooling pipe connected to the delivery pump and the condenser, respectively. A liquid inlet is connected to one side of the delivery pump.

[0008] As a further embodiment of this utility model: the drainage component includes a drainage pipe connected to the bottom of the cooling chamber, a water collection trough is provided at the bottom of the cooling chamber, the position of the drainage pipe is adapted to the water collection trough, and a control valve is connected to one end of the drainage pipe.

[0009] As a further improvement of this utility model: a connecting flange is provided at the liquid inlet on one side of the delivery pump, and a rubber gasket is provided on one side of the connecting flange.

[0010] As a further improvement of this utility model: the bottom of the main body of the high temperature and high humidity pulse dust collector is provided with several sets of support legs, the bottom of the support legs is provided with a fixing frame, the fixing frame is provided with several sets of screw holes, and the bottom of the fixing frame is provided with a rubber buffer pad.

[0011] As a further improvement of this utility model: a fixed shaft is provided at the bottom of the filter chamber, and a limit block can be rotatably installed through the fixed shaft. The size and position of the limit block are adapted to the sealing baffle.

[0012] The beneficial effects of this utility model are as follows: 1. By setting up a filter assembly, the incoming exhaust gas can be pre-filtered. The filter plate can filter out large particulate impurities carried in the exhaust gas, thereby preventing large particulate impurities from entering the main body of the high temperature and high humidity pulse dust collector along with the exhaust gas. This can prevent large particulate impurities from entering and causing blockage, and at the same time, it can prevent the impact of large particulate impurities from increasing wear and reducing service life. The vibration motor can drive the filter plate to vibrate, thereby cleaning it and preventing excessive impurities from adhering and causing blockage.

[0014] 3. By installing a connecting flange, the connection point can be reinforced when connecting the liquid supply pipeline to the liquid inlet of the delivery pump. This reinforcement can prevent the connection from breaking and causing leakage when injecting coolant. Rubber gaskets can also increase the sealing of the connection. Attached Figure Description

[0017] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Example 1 A tail gas filtration mechanism for a high-temperature and high-humidity pulse dust collector, such as Figure 1-4As shown, the system includes a filter assembly, which comprises a high-temperature and high-humidity pulse dust collector body 1. A cooling chamber 2 is connected to one side of the body 1, and a filter chamber 6 is connected to one end of the cooling chamber 2. A cooling and dehumidification assembly for cooling and dehumidification is installed on one side of the cooling chamber 2. Fixed supports 22 are symmetrically arranged on the inner walls of both sides of the filter chamber 6. A spring 23 is installed on one side of each fixed support 22, and a filter plate 19 is installed at the other end of each spring 23. The size of the filter plate 19 is adapted to the filter chamber 6, and the filter plate 19 has several sets of sieve holes arranged sequentially. A guide hole is provided in the fixed support 22, through which a guide rod 24 can be slidably installed. One end of the guide rod 24 is fixed to the filter plate 19. A fixed seat 18 is installed on the inner wall of one side of the filter chamber 6. A drive motor 25 is set on one side of the fixed seat 18. A connecting shaft 17 is connected to the output end of the drive motor 25. One end of the connecting shaft 17 is rotatably installed through the fixed seat 18. An adjustment frame 16 is set on the connecting shaft 17. A vibration motor 15 is set on one side of the adjustment frame 16. A protective pad is set on one end of the vibration motor 15. The corners of the protective pad are rounded. A sludge removal component for removing impurities is set on one side of the filter chamber 6. A drainage component for removing condensate is set on one side of the cooling chamber 2. An air supply pipe 7 is connected to one side of the filter chamber 6. During operation, the exhaust gas can be connected to the air supply pipe 7 to enter the filter chamber 6. After passing through the filter chamber 6 and the cooling chamber 2, the exhaust gas enters the main body 1 of the high-temperature and high-humidity pulse dust collector for dust removal and purification. After entering the filter chamber 6 through the air supply pipe 7, the exhaust gas is filtered by the filter plate 19. The sieve holes of the filter plate 19 can filter out large particulate impurities carried in the exhaust gas, thus preventing large particulate impurities from entering the main body 1 of the high-temperature and high-humidity pulse dust collector along with the exhaust gas. This avoids blockage caused by large particulate impurities and also prevents wear and tear and reduced service life caused by large particulate impurities. After a certain period of use, the drive motor 25 can be started to control the continuous operation. The shaft 17 rotates, thereby synchronously controlling the rotation of the adjusting frame 16. The rotation of the adjusting frame 16 controls the movement of the vibration motor 15 to bring the protective pad into contact with the filter plate 19. After the protective pad is in contact with the filter plate 19, the vibration motor 15 is started to control the vibration of the filter plate 19. The vibration of the filter plate 19 can clean the impurities attached to it, avoiding the accumulation of impurities and blockage. During vibration, the deformation of the spring 23 can ensure that the filter plate 19 can vibrate normally. The guide rod 24 slides in the guide hole to prevent the filter plate 19 from shifting. The arc-shaped protective pad can fully fit with the filter plate 19. The model of the high temperature and high humidity pulse dust collector body 1 can use any mature product on the market. The impurity removal assembly includes a mounting base 11, which is installed at the bottom of the filter chamber 6. The bottom of the filter chamber 6 has a discharge port, the position and size of which are adapted to the filter plate 19. A sealing baffle 10 is rotatably installed on the mounting base 11, and the size and position of the sealing baffle 10 are adapted to the discharge port. During use, the sealing baffle 10 and the mounting base 11 are equipped with a certain amount of damping to prevent unnecessary rotation. After a certain period of use, the sealing baffle 10 can be rotated to open the discharge port at the bottom of the filter chamber 6. After opening, large particles of impurities that have been filtered out can be discharged, and impurities cleaned on the filter plate 19 can also be discharged to prevent impurities from accumulating in the cooling chamber 2 and affecting the air intake efficiency. After the impurities are discharged, the sealing baffle 10 can be rotated to close the discharge port at the bottom of the filter chamber 6, thereby avoiding affecting the normal air intake filtration. The cooling and dehumidification assembly includes a delivery pump 3, which is installed on the top of the cooling chamber 2. A condenser 5 is provided on one side of the delivery pump 3. One end of the delivery pump 3 is connected to a delivery pipe 4, and the other end of the delivery pipe 4 is connected to the condenser 5. A cooling pipe 20 is provided inside the cooling chamber 2. The two ends of the cooling pipe 20 are connected to the delivery pump 3 and the condenser 5, respectively. A liquid inlet is connected to one side of the delivery pump 3. During operation, a pipe is connected to one side of the condenser 5 to drain condensate. Coolant is injected through the inlet of the delivery pump 3. The delivery pump 3 delivers the coolant, which is then fed into the condenser 5 via the delivery pipe 4. After cooling in the condenser 5, the cooled coolant is delivered to the cooling pipe 20. The flow of coolant within the cooling pipe 20 lowers the temperature inside the cooling chamber 2, creating a low-temperature environment. This low-temperature environment, combined with the coolant flowing within the cooling pipe 20, allows for better cooling of the exhaust gas after it has been filtered and enters the cooling chamber 2. The system cools the exhaust gas to room temperature, facilitating subsequent processing. The coolant flowing through the cooling pipe 20 dehumidifies the exhaust gas, and the moisture carried by the high-humidity exhaust gas is condensed through the cooling pipe 20. The condensed water is discharged through the drainage component. After cooling and dehumidification, the exhaust gas enters the main body 1 of the high-temperature and high-humidity pulse dust collector through the cooling chamber 2 for further processing. The coolant flowing through the cooling pipe 20 can return to the transfer pump 3, which then transports it to the condenser 5 for cooling. The circulating transport ensures the cooling and dehumidification effect. The drainage assembly includes a drain pipe 12, which is connected to the bottom of the cooling chamber 2. A water collection trough is provided at the bottom of the cooling chamber 2. The position of the drain pipe 12 is adapted to the water collection trough. A control valve is connected to one end of the drain pipe 12. During use, the condensate that is generated by the coolant flowing through the cooling pipe 20 can accumulate in the water collection tank at the bottom of the cooling chamber 2. The accumulated condensate can be drained through the drain pipe 12 by opening the control valve, thereby avoiding the situation where too much condensate accumulates and affects dehumidification. To facilitate pipe connection, such as Figure 3 As shown, a connecting flange 21 is provided at the liquid inlet on one side of the transfer pump 3, and a rubber gasket is provided on one side of the connecting flange 21. When in use, the connection can be reinforced by connecting flange 21 when connecting the liquid supply pipe to the liquid filling port of the delivery pump 3. Reinforcement can prevent the connection from breaking and causing leakage when injecting coolant. The rubber gasket can increase the sealing of the connection. In order to fix, such as Figure 2 As shown, the main body 1 of the high temperature and high humidity pulse dust collector is provided with several sets of support legs 13 at the bottom. The bottom end of the support legs 13 is provided with a fixed frame 14. The fixed frame 14 is provided with several sets of screw holes and a rubber buffer pad is provided at the bottom end of the fixed frame 14. When in use, the bolts of the fixing bracket 14 can be aligned with the bolts at the fixing position and then tightened with nuts to complete the fixing. After fixing, unnecessary displacement can be avoided. The support legs 13 can provide support and maintain stability, and the rubber buffer pads can make the fixing more secure.

[0020] Example 2 To prevent the sealing baffle 10 from opening accidentally, refer to... Figure 2 A tail gas filtration mechanism for a high temperature and high humidity pulse dust collector is provided. Compared with embodiment 1, this embodiment makes the following improvements: a fixed shaft 8 is provided at the bottom of the filter chamber 6, and a limit block 9 can be rotatably installed through the fixed shaft 8. The size and position of the limit block 9 are adapted to the sealing baffle 10. During use, the limiting block 9 and the fixed shaft 8 are equipped with a certain amount of damping to avoid unnecessary rotation. After the sealing baffle 10 is closed, the limiting block 9 can be controlled to rotate and lock the sealing baffle 10 to limit and fix it, thereby preventing the sealing baffle 10 from being opened accidentally and causing air leakage.
