Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flue gas dust removal, in particular to a sintered plate dust collector for treating high-humidity flue gas. Background Technique
[0002] The sintered plate dust collector uses a unique wavy sintered plate filter core to replace the traditional cloth bag. Since the surface of the sintered plate has been deeply treated, the pore size is small and uniform, and it has hydrophobicity and is not easy to adhere to dust with a higher water content. Therefore, the sintered plate dust collector is the best choice when treating dust with a higher water content and fibrous dust. Therefore, the sintered plate dust collector is usually used to perform dust removal operations on high-humidity flue gas. When the existing sintered plate dust collector is in use, when cleaning the dust on the outer surface of the sintered plate inside, the pulse backwashing method is used for cleaning. However, for dirt with strong adhesion, it is very difficult to clean completely through pulse backwashing.
[0003] For this reason, we have proposed a sintered plate dust collector for treating high-humidity flue gas. Content of the Utility Model
[0004] The purpose of the utility model is to provide a sintered plate dust collector for treating high-humidity flue gas to solve the existing inconvenient technical problems.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A sintered plate dust collector for treating high-humidity flue gas, the key point is that it includes a baffle fixedly installed inside the dust collector housing, the baffle divides the inner cavity of the dust collector housing into an upper purification chamber and a lower dust removal chamber up and down. Inside the dust removal chamber and on the baffle, a number of equally spaced sintered plates are fixedly installed. The side part and the middle part of the top of the dust collector housing are respectively fixedly connected with an air inlet pipe and an air outlet pipe. The bottom of the ash hopper below the dust collector housing is fixedly connected with a sewage discharge pipe. A pulse cleaner for back-blowing the sintered plate is fixedly installed on the dust collector housing. Scraping strips that are in contact with the side surfaces of the sintered plates are respectively arranged on the left and right side surfaces of the sintered plates. A driving mechanism for driving the scraping strips to move up and down vertically is installed at the top of the dust collector housing. A proximity switch and an audible and visual alarm are arranged at the top of the dust collector housing. The proximity switch, the audible and visual alarm and an external power supply are connected by wires to form a circuit. A triggering mechanism for triggering the closing of the proximity switch is arranged on the baffle. When the pressure in the dust removal chamber becomes larger, the proximity switch is closed through the triggering mechanism to form an alarm of the audible and visual alarm.
[0006] Further, the driving mechanism includes an electric telescopic rod fixedly installed at the top of the dust collector housing. The telescopic end of the electric telescopic rod moves vertically downward through the baffle and is fixedly connected with a connecting block. The connecting block is fixedly connected with the ends of the scraping strips.
[0007] Further, the number of the electric telescopic rods is two, and they are symmetrically arranged on both sides of the air outlet pipe front and back. The number of the connecting blocks is two, and they are respectively fixedly connected to the front and back ends of each scraping strip. The telescopic ends of the electric telescopic rods on the same side are fixedly connected to the connecting blocks.
[0008] Further, the triggering mechanism includes a warning rod arranged on the left side of the purification chamber. The bottom end of the warning rod is movably inserted into a plug hole opened on the upper surface of the baffle. A through hole coaxial with the plug hole is opened on the lower surface of the baffle, and the through hole communicates with the plug hole. The top end of the warning rod vertically passes through the top end of the dust collector housing upward. A proximity switch is arranged directly above the top end of the warning rod. The proximity switch is fixedly installed on a connecting frame, and the connecting frame is fixedly installed on the dust collector housing. The connecting frame and the top end of the warning rod are fixedly connected by a spring.
[0009] Further, the shape of the scraping strip is corrugated and fits the corrugated surface of the sintered plate.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] When it is necessary to clean the sintered plate, start the driving mechanism to drive the scraping strip to move upward, and the stubborn dirt on the outer surface of the sintered plate will be scraped off. After the dirt is scraped off, then start the pulse cleaner to generate pulse air to blow and clean the sintered plate in the reverse direction, so as to avoid incomplete cleaning due to stubborn dirt adsorbed on the sintered plate.
[0012] When the sintered plate is in use and has been severely blocked after a long use time and the pulse cleaner fails to clean it, the pressure in the dust removal chamber below the baffle on the outside of the sintered plate will increase, which will thus trigger the triggering mechanism. Through the triggering mechanism, the proximity switch is started, thereby connecting the external power supply to supply power to the sound and light alarm, and realizing the sound and light alarm to remind the staff that the sintered plate needs to be replaced.

[0019] 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. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0020] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.
[0021] As Figures 1 to 5 shown in a specific embodiment of a plastic sintered plate dust collector for treating high-humidity flue gas, it includes a baffle 8 fixedly installed inside the dust collector housing 1. The baffle 8 divides the inner cavity of the dust collector housing 1 into an upper and a lower part, namely a purification chamber 17 and a dust removal chamber 18. A plurality of equally spaced plastic sintered plates 10 are fixedly installed in the dust removal chamber 18 and on the baffle 8. The side and the middle part of the top of the dust collector housing 1 are respectively fixedly connected with an inlet pipe 3 and an outlet pipe 11. The inlet pipe 3 is communicated with the dust removal chamber 18, and the outlet pipe 11 is communicated with the purification chamber 17. The bottom of the ash hopper 6 below the dust collector housing 1 is fixedly connected with a drain pipe 7. A pulse cleaner 4 is fixedly installed on the dust collector housing 1. The pulse cleaner 4 is a prior art, and the plastic sintered plate 10 is back-blown by using the method of compressed gas back-blowing. Scraping strips 12 are respectively arranged on the left and right side surfaces of the plastic sintered plate 10, and the scraping strips 12 are in contact with the side surfaces of the plastic sintered plate 10. A driving mechanism is installed at the top of the dust collector housing 1, and the driving mechanism is used to drive the scraping strips 12 to move up and down in the vertical direction. A proximity switch 16 and an acousto-optic alarm 5 are arranged at the top of the dust collector housing 1. The proximity switch 16, the acousto-optic alarm 5 and an external power supply are connected by wires to form a circuit. A triggering mechanism is arranged on the baffle 8, and the triggering mechanism is used to trigger the closing of the proximity switch 16. When the pressure in the dust removal chamber 18 becomes larger, the proximity switch 16 is closed through the triggering mechanism, realizing the acousto-optic alarm of the acousto-optic alarm 5. Both the acousto-optic alarm 5 and the proximity switch 16 adopt mature prior arts;
[0022] In the normal dust removal state of this embodiment, the dirty air from the outside is introduced through the intake pipe 3, and clean air is discharged through the outlet pipe 11. The sintered plate 10 plays a filtering role. When it is necessary to clean the sintered plate 10, the driving mechanism is started to drive the scraping strip 12 to move upward, and the stubborn dirt on the outer surface of the sintered plate 10 will be scraped off. After the dirt is scraped off, the pulse cleaner 4 is started to generate pulsed air to backflush and clean the sintered plate 10, which can avoid incomplete cleaning due to the stubborn dirt adsorbed on the sintered plate 10. And when the sintered plate 10 is in use and the use time is relatively long, the sintered plate 10 is severely blocked and the pulse cleaner 4 cannot clean it effectively. At this time, the pressure in the dust removal chamber 18 below the baffle 8 outside the sintered plate 10 will increase, which will trigger the trigger mechanism. Through the trigger mechanism, the proximity switch 16 is started, thereby connecting the external power supply to supply power to the sound and light alarm 5, and realizing the sound and light alarm to remind the staff that the sintered plate 10 needs to be replaced.
[0023] The driving mechanism of this embodiment includes an electric telescopic rod 2 fixedly installed at the top of the dust collector housing 1. The telescopic end of the electric telescopic rod 2 moves downward vertically through the baffle 8, and the telescopic end of the electric telescopic rod 2 is fixedly connected to the connecting block 13. The connecting block 13 is fixedly connected to the ends of each scraping strip 12. Specifically, the number of electric telescopic rods 2 is two, and they are symmetrically arranged before and after the outlet pipe 11. The number of connecting blocks 13 is two, which are respectively fixedly connected to the front and rear ends of each scraping strip 12. The telescopic ends of the electric telescopic rods 2 on the same side are fixedly connected to the connecting block 13. By starting the electric telescopic rod 2, the connecting block 13 is driven to move up and down, and the connecting block drives the scraping strip 12 to move up and down, and the scraping strip 12 wipes and cleans the outer side surface of the sintered plate 10.
[0024] The trigger mechanism of this embodiment includes a warning rod 9 arranged on the left side of the purification chamber 17. The bottom end of the warning rod 9 is movably inserted into the insertion hole. The insertion hole is opened on the upper surface of the baffle 8. A through hole 19 is opened on the lower surface of the baffle 8. The through hole 19 and the insertion hole are coaxially arranged and communicate with each other. The top end of the warning rod 9 moves upward vertically through the top end of the dust collector housing 1. A proximity switch 16 is arranged directly above the top end of the warning rod 9. The proximity switch 16 is fixedly installed on the connecting frame 14. The connecting frame 14 is fixedly installed on the dust collector housing 1. The connecting frame 14 and the top end of the warning rod 9 are fixedly connected by a spring 15. When the sintered plate 10 is in use and the use time is relatively long, the sintered plate 10 is severely blocked and the pulse cleaner 4 cannot clean it effectively. At this time, the pressure outside the sintered plate 10 below the baffle 8 will increase. The pressure passes through the through hole 19, which will push up the warning rod 9 to move upward, so as to approach the proximity switch 16. The proximity switch 16 is started, thereby connecting the external power supply to supply power to the sound and light alarm 5, and realizing the sound and light alarm to remind the staff that the sintered plate 10 needs to be replaced.
[0025] Specifically, the shape of the scraping strip 12 is corrugated and fits with the corrugated surface of the sintered plate 10, which can effectively clean the outside of the sintered plate 10.
