[0004] While the aforementioned existing technologies have barrier devices that can effectively remove dust from the filter bags, they lack a cooling structure. Consequently, when treating high-temperature flue gas, the internal temperature of the device rises, which not only affects the dust removal efficiency but also accelerates the aging and wear of the filter bags, increasing maintenance costs. Therefore, the market urgently needs to develop a pulse-jet bag filter dust collector with a cooling structure to help solve the existing problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model effectively solves the problem of internal temperature rise during dust removal of high-temperature flue gas by integrating water tank one and water tank two, along with corresponding temperature guiding plates and cooling baffles. An external cold water supply device provides cold water to water tank one through an inlet pipe, and the cooling energy is transferred to the inside of the device through temperature guiding plates one and two. Simultaneously, the water cavity inside the cooling baffles and its connected piping system not only increase the heat exchange area but also improve the heat exchange efficiency, thereby effectively reducing the internal temperature of the device, slowing down the aging and wear rate of the filter bags, extending their service life, and significantly reducing operation and maintenance costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a pulse-jet bag filter dust collector with a cooling structure, comprising a device housing 1, a dust hopper 3 fixedly installed at the bottom of the device housing 1, an air inlet pipe 2 fixedly installed on one side of the dust hopper 3, and the air inlet pipe 2 extending into the interior of the dust hopper 3; water tank 1 7 and water tank 2 8 symmetrically fixedly installed on the lower sides of the device housing 1, respectively; a water inlet pipe 6 fixedly installed on the lower side of one side of water tank 1 7, the water inlet pipe 6 being connected to a cold water supply device; and a drain pipe 9 fixedly installed on the upper side of one side of water tank 2 8; and drain pipes 9 extending along the lower sides of the interior of the device housing 1. Temperature-conducting plates 10 and 14 are fixedly installed on one side of water tank 7 and water tank 8, respectively. Both temperature-conducting plates 10 and 14 are made of die-cast aluminum alloy. Cooling baffle 12 is set inside the device box 1. Water cavity 1201 is set inside the cooling baffle 12. Pipe 11 and pipe 2 13 are symmetrically fixedly installed on both sides of the cooling baffle 12. Pipe 11 and pipe 2 13 are connected to water cavity 1201. The ends of pipe 11 and pipe 2 13 away from cooling baffle 12 are connected to water tank 7 and water tank 8, respectively.

[0024] During operation, high-temperature flue gas is input through inlet pipe 2. Cold water is supplied to water tank 7 through inlet pipe 6 using an external cold water supply device. Then, water is delivered to water tank 8 through pipe 11, cooling baffle 12, and pipe 2 13. The cooling capacity of the water is transferred to the inside of the device through temperature guide plate 10 and temperature guide plate 2 14. At the same time, the cooling baffle 12 with water cavity 1201 is not only located inside the device housing 1 but also above the outlet of inlet pipe 2, which can directly exchange heat with the high-temperature flue gas. This increases the heat exchange area and improves the heat exchange efficiency, thereby effectively reducing the temperature inside the device, effectively slowing down the aging and wear rate of the filter bags, extending the service life of the filter bags, and thus significantly reducing operation and maintenance costs.

[0025] Furthermore, a partition 17 is fixedly installed inside the device housing 1, and multiple venturi tubes 16 are fixedly installed below the partition 17, with the upper ends of the venturi tubes 16 extending to the upper surface of the partition 17. A filter bag 15 is fixedly installed below the venturi tubes 16, and an exhaust pipe 5 is fixedly installed on the upper side of one side of the device housing 1. Through the combination of the venturi tubes 16 and the filter bag 15, particulate matter in the flue gas can be filtered more effectively, improving the dust removal effect.

[0026] Furthermore, an equipment box 18 is fixedly installed on the upper side of the other side of the device housing 1. The equipment box 18 is equipped with a pulse mechanism, and a pulse controller is fixedly installed at the front end of the equipment box 18. The pulse mechanism includes an air tank 19, an electromagnetic pulse valve 20, and a gas pipe 21. The input and output ends of the electromagnetic pulse valve 20 are connected to the air tank 19 and the gas pipe 21, respectively. One end of the gas pipe 21 extends into the interior of the device housing 1. A blowpipe 23 is installed on the upper side of the interior of the device housing 1. A hose 22 is fixedly installed on one side of the blowpipe 23. One end of the hose 22 is fixedly connected to the gas pipe 21. Multiple jet nozzles are fixedly installed below the blowpipe 23. The number of jet nozzles is the same as that of the Venturi tubes 16 and their positions correspond to each other. The pulse mechanism controls the gas release of the air tank 19 through the electromagnetic pulse valve 20, and uses the gas pipe to deliver high-pressure gas to the blowpipe 23. The jet nozzles clean the filter bag 15, which can prevent the filter bag 15 from clogging.

[0027] Furthermore, a U-shaped plate 24 is fixedly installed on the upper part of the device housing 1, and an electric cylinder 25 is fixedly installed on the upper part of the U-shaped plate 24. The push rod end of the electric cylinder 25 slides through the U-shaped plate 24 and is fixedly connected to the blow pipe 23. Guide rods 26 are symmetrically arranged on both sides of the electric cylinder 25. The lower end of the guide rod 26 slides through the U-shaped plate 24 and is fixedly connected to the blow pipe 23. The electric cylinder 25 is fixedly connected to the blow pipe 23 through the push rod, which can drive the blow pipe 23 to move up and down, thereby realizing a stable dust cleaning operation. The setting of the guide rod 26 increases the stability of the blow pipe 23 during the movement process, prevents poor dust cleaning effect caused by shaking or deviation, and helps to improve dust cleaning efficiency.

[0028] Furthermore, a heat-conducting plate 3 1202 is fixedly installed below the cooling baffle 12. The heat-conducting plate 3 1202 is made of die-cast aluminum alloy material, which has good thermal conductivity, improves heat exchange efficiency, and enhances the cooling effect.

[0029] Furthermore, a dust discharge cylinder 4 is fixedly installed below the dust hopper 3. A sealing plate is inserted into the inside of the dust discharge cylinder 4. The dust discharge cylinder 4 allows the dust in the dust hopper to be discharged easily, while the sealing plate makes it easy to seal or open the dust discharge cylinder 4, increasing the flexibility of dust discharge.

[0030] Working principle: During use, high-temperature flue gas enters the ash hopper 3 through the inlet pipe 2. At the same time, the external cold water supply equipment supplies cold water to the water tank 7 through the water inlet pipe 6. The cold water enters the water chamber 1201 of the cooling baffle 12 through the pipe 11. After exchanging heat with the high-temperature flue gas, it flows into the water tank 8 through the pipe 13. Through heat exchange, the internal temperature of the device is effectively reduced, and the aging of the filter bag is slowed down. Then the flue gas continues to rise and passes through the filter bag 15 to filter out particulate matter. The clean gas is discharged through the exhaust pipe 5.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
