Description
Technical Field
[0001] The utility model relates to the technical field of bag dust collectors, in particular to a pulse air source treatment mechanism for an anti-condensation bag dust collector. Background Technique
[0002] A bag dust collector is a dust removal device used in the industrial production process, mainly used for collecting and treating dust particles in the air. Its working principle is to use a cloth bag as a filtering medium. When the dust-containing gas passes through the cloth bag, the dust particles are intercepted on the surface of the cloth bag, and the clean gas is discharged through the cloth bag.
[0003] However, in the prior art, since the flue gas to be filtered and purified has a certain temperature, when the temperature of the flue gas is too high, methods such as spraying water and heat exchange are usually used to reduce the temperature of the flue gas. However, if the flue gas contains a large amount of moisture, then after the temperature of the flue gas decreases, the phenomena of condensation and bag sticking will occur. After condensation on the surface of the cloth bag, a water film will be formed, resulting in the adhesion of dust contained in the soot to the surface of the cloth bag, thereby increasing the resistance of the cloth bag. This will not only affect the dust removal efficiency of the cloth bag, but also may cause damage to the cloth bag. Therefore, we provide a pulse air source treatment mechanism for an anti-condensation bag dust collector. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0024] The present utility model provides a technical solution: As Figures 1 - 5As shown in the figure, in this embodiment, a pulse gas source treatment mechanism for an anti-condensation bag filter includes: a heating mechanism 1. The heating mechanism 1 includes a dust collector housing 11. On one side of the dust collector housing 11, there is an installation frame 12. At the bottom of the installation frame 12, there is a support 13. At the top of the installation frame 12, there are two blowers 14. On the opposite sides of the two blowers 14, there are air delivery pipes 15. Inside the support 13, there is a heating component 16. The heating component 16 includes a heating box 1601. Inside the heating box 1601, there is an electric heating plate 1602. In the card slot opened at the bottom of the heating box 1601, there is an air collecting hopper 1603. One side of the dust collector housing 11 is fixedly connected to the installation frame 12. The bottom of the blower 14 is fixedly installed on the top of the installation frame 12. One end of the air delivery pipe 15 is butted against the output end of the blower 14. The other end of the air delivery pipe 15 penetrates through the installation frame 12 and communicates with the inside of the heating box 1601. At the bottom of the air collecting hopper 1603, there is a gas collecting pipe 17. The outside of the heating box 1601 is fixedly installed inside the support 13. The electric heating plate 1602 is fixedly installed inside the heating box 1601. The inner wall of the card slot opened at the bottom of the heating box 1601 is fixedly connected to the outside of the air collecting hopper 1603. The bottom of the air collecting hopper 1603 is butted against the top of the gas collecting pipe 17. In the card slot opened on one side of the gas collecting pipe 17, there is a gas collecting valve 18. At the bottom end of the gas collecting pipe 17, there is an air inlet 19. Inside the dust collector housing 11, there is an installation plate 110. The bottom end of the gas collecting pipe 17 is butted in the card slot opened on the top side of the air inlet 19. The end of the air inlet 19 close to the dust collector housing 11 is butted in the card slot opened on the side of the dust collector housing 11 away from the motor 21. The outside of the installation plate 110 is fixedly connected to the inner wall of the dust collector housing 11. At multiple card slots opened on the installation plate 110, there are dust-proof cloth bags 111. At multiple card slots opened on the installation plate 110, there are fixedly connected dust-proof cloth bags 111. The bottom of the dust collector housing 11 is fixedly connected to an ash hopper 31. In the card slot opened on the side of the dust collector housing 11 away from the installation frame 12, there is a butted exhaust pipe 32. At the top of the air inlet 19, there is a gas collecting valve 33. On the side of the dust collector housing 11 away from the installation frame 12, there is a cleaning mechanism 2.
[0025] In this embodiment, when the staff needs to use the device to purify and filter the flue gas, the flue gas to be filtered can be transmitted into the dust collector housing 11 through the air inlet 19. The flue gas will be filtered through the dust-proof cloth bag 111, and the filtered gas will be discharged to the outside through the exhaust pipe 32. However, the flue gas itself may have a certain temperature and contain some moisture. Therefore, condensation and bag sticking phenomena will occur after the temperature of the flue gas decreases. Therefore, when the device stops working, the staff should start the blower 14 and the heating component 16 in time. Then, the heating plate will heat the inside of the heating box 1601, and the heat will be stored inside the heating box 1601. However, the wind generated after the blower 14 starts will be transmitted into the heating box 1601 through the air delivery pipe 15. Then, the transmission of the wind will transfer the heat inside the heating box 1601 into the dust collector housing 11 through the air-gathering hopper 1603, the air-collecting pipe 17, and the air inlet 19. When mentioned here, the air-gathering valve 33 should be closed when guiding the heat to ensure that the heat can be correctly guided into the dust collector housing 11. Therefore, the gradually accumulated heat in the dust collector housing 11 will heat and dry the dust-proof cloth bag 111, ensuring that the dust removal bag remains dry, avoiding the occurrence of bag sticking and condensation, and ensuring the dust removal efficiency of the dust-proof cloth bag 111.
[0026] As Figure 2 and Figure 5 As shown, the cleaning mechanism 2 includes a motor 21. A support plate 34 is fixedly connected to one side of the dust collector housing 11 away from the mounting frame 12. The top of the support plate 34 is fixedly connected to the outside of the motor 21. The output end of the motor 21 is fixedly connected to one end of a rotating rod 22. The other end of the rotating rod 22 passes through one side of the dust collector housing 11 close to the motor 21 and is fixedly connected to the inner surface of a bearing seat 24. The outside of the bearing seat 24 is fixedly connected to one side of the inner wall of the dust collector housing 11 away from the motor 21. A plurality of clappers 23 are fixedly connected to the outside of the rotating rod 22.
[0027] In this embodiment, after the dust-proof cloth bag 111 is dried, the cloth bag will remain in a dry state. Therefore, the staff can start the motor 21. Then, the start of the motor 21 will drive the clappers 23 on the rotating rod 22 to rotate in a circle. Then, the clappers 23 will continuously beat these dust-proof cloth bags 111. Therefore, the dust and powder will fall into the ash hopper 31, which helps to maintain the filtering effect of the cloth bag and prevent excessive accumulation of dust and powder on the surface of the cloth bag, resulting in a decrease in the filtering efficiency.
[0028] The present invention provides a pulse gas source treatment mechanism for an anti-condensation bag dust collector, and the specific working principle is as follows:
[0029] After the equipment finishes working, the staff will promptly start the blower 14 and the heating component 16. In this way, the heating plate will start to heat the interior of the heating box 1601, causing heat to gradually accumulate within the heating box 1601. When the blower 14 is started, the generated wind will be transmitted through the air delivery pipe 15 into the heating box 1601. Along with the transmission of the wind, the heat inside the heating box 1601 will be transmitted through the air-gathering hopper 1603, the air-collecting pipe 17, and the air inlet 19 into the dust collector housing 11. In this way, the heat gradually accumulating in the dust collector housing 11 will heat and dry the dust-proof cloth bags 111. This process ensures that the dust-proof cloth bags remain dry, avoiding the occurrence of bag sticking and condensation. After the dust-proof cloth bags 111 have been dried, they will remain in a dry state, which allows the staff to start the motor 21. It will drive the flap 23 on the rotating rod 22 to rotate in a circle. These flaps 23 will continuously beat the dust-proof cloth bags 111 to remove the dust and powder therein. Through this continuous beating action, the dust and powder will be effectively removed from the dust-proof cloth bags 111.
[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
