Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection equipment technology, specifically to a dry deacidification tower with an automatic ash removal and slag removal mechanism. Background Technology
[0002] Dry desulfurization towers are important equipment in industrial waste gas treatment. They purify waste gas by spraying alkaline adsorbents (such as activated carbon and quicklime) into the tower to react chemically with acidic substances in the waste gas.
[0003] Utility model patent CN213885688U discloses a high-efficiency dry desulfurization tower, comprising a desulfurization tower, a flue gas inlet pipe fixedly installed on the left side of the desulfurization tower, a desulfurization medium inlet pipe fixedly installed on the right side of the desulfurization tower, a mixing frame fixedly installed inside the desulfurization tower, a fixing buckle fixedly installed on the top of the mixing frame, mixing fan blades fixedly installed inside the mixing frame, a linkage shaft fixedly installed at the bottom of the mixing frame, a linkage rod fixedly connected to the bottom of the linkage shaft, and a protective sleeve fixedly installed at the bottom of the linkage shaft and outside the linkage rod. This high-efficiency dry desulfurization tower, by re-disturbing and redistributing the flow direction of the flue gas and the desulfurization medium, makes the mixing of the flue gas and the desulfurization medium more uniform, while also delaying the residence time of the flue gas in the desulfurization tower, increasing the reaction time with the desulfurization medium, allowing the desulfurization medium to fully react, improving desulfurization efficiency, and reducing desulfurization costs.
[0004] Although the above technical solutions have corresponding advantages, after long-term operation, the existing dry deacidification towers are prone to accumulating a large amount of ash and slag produced by the reaction on the inner wall and bottom of the tower. If not cleaned in time, it will lead to uneven airflow distribution in the tower and insufficient contact between the adsorbent and the waste gas, thus reducing the deacidification efficiency.
[0005] Traditional methods of ash removal and slag removal mostly rely on manual, periodic entry into the tower for cleaning. This is not only labor-intensive and involves harsh working environments, but also requires interrupting equipment operation, affecting production continuity, and is difficult to meet the demand for efficient and continuous ash removal and slag removal. In view of this, we propose a dry acid removal tower with an automatic ash removal and slag removal mechanism. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-3 This utility model provides a technical solution: a dry deacidification tower with an automatic ash removal and slag removal mechanism, including a tower body 1. A conical ash hopper 10 is detachably installed at the bottom of the tower body 1. A waterproof motor 2 is installed inside the conical ash hopper 10. A stirring shaft 20 is fixedly installed at the end of the output shaft of the waterproof motor 2. A cleaning scraper 21 is fixedly installed on the stirring shaft 20. The cleaning scraper 21 rotates to scrape the inner wall of the conical ash hopper 10 to remove impurities. A top cover 3 is fixedly installed at the top of the tower body 1. A water ring 31 is installed inside the top cover 3. Multiple high-pressure vertical flushing nozzles 33 are fixedly installed at the bottom of the water ring 31 for high-pressure flushing of the inner wall of the tower body 1. An air outlet hood 34 is fixedly installed at the top of the top cover 3, so as to realize the high-pressure flushing operation using the high-pressure vertical flushing nozzles 33 to achieve the effect of cleaning impurities on the inner wall.
[0032] In this embodiment, the inner wall of the conical ash hopper 10 is inclined downward at a angle of 45° to 60°. A vertical pipe 11 is fixedly installed at the bottom of the conical ash hopper 10, so that the ash and slag converge towards the vertical pipe 11 under the action of gravity, reducing residue and making the ash and slag discharge smoother, thereby improving the slag discharge efficiency.
[0033] like Figure 1 As shown, a screw feeder 12 is installed at the bottom end of the vertical pipe 11. The bottom end of the vertical pipe 11 is fixedly installed on the feed end pipe of the screw feeder 12. The screw feeder 12 can continuously transport ash and slag, avoid blockage of the vertical pipe 11, make the ash and slag discharge process more stable, and achieve the effect of ensuring the continuity of slag discharge.
[0034] like Figure 3 As shown, an upper fixing ring 13 is fixedly installed on the bottom cylinder of the tower body 1, and a lower fixing ring 14 is fixedly installed on the top of the conical ash hopper 10. The lower fixing ring 14 can be detachably installed on the bottom surface of the upper fixing ring 13, which facilitates the inspection and cleaning of the inside of the conical ash hopper 10 and improves the convenience of maintenance.
[0035] like Figure 3 As shown, an inner support frame 15 is fixedly installed on the inner wall of the bottom cylinder of the tower body 1. The waterproof motor 2 is detachably installed on the inner support frame 15 by multiple fastening bolts, which makes the waterproof motor 2 more stable, reduces vibration during operation, ensures the stable operation of the cleaning scraper 21, and achieves the effect of enhancing the stability of the equipment.
[0036] like Figure 3 As shown, a waterproof heat sink 22 is detachably installed on the top surface of the inner support frame 15. The waterproof heat sink 22 is fitted over the outside of the waterproof motor 2. The waterproof heat sink 22 has an inverted V-shaped structure, which not only prevents water from damaging the motor, but also allows the rinsing water to slide down along the cover and clean the surface, so that the motor is effectively protected and easy to clean, achieving the effect of both protection and cleaning.
[0037] In this embodiment, the top cover 3 is provided with an inner chamber 30, and the water ring 31 is located in the inner chamber 30. The water outlet of the high-pressure vertical flushing nozzle 33 is flush with the inner wall of the tower body 1 in the vertical direction, so that the water flows down the inner wall of the tower body to ensure that the flushing range is comprehensive and achieve the effect of improving the cleaning effect of the inner wall of the tower body.
[0038] It is worth noting that an exhaust pipe 35 is fixedly installed at the top of the exhaust hood 34, and a central hole 311 is provided at the center of the water ring 31. A water inlet pipe 32 that passes through the tower body 1 is fixedly installed on the water ring 31. The central hole 311 of the water ring 31 provides a channel for the airflow to be discharged, and the water inlet pipe 32 ensures the water supply, so that the purified gas can be discharged smoothly without affecting the flushing water supply, thus achieving the effect of taking into account both exhaust and flushing functions.
[0039] Finally, it should be noted that the waterproof motor 2, screw feeder 12, corresponding control system and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.
[0040] When using the dry deacidification tower with automatic ash removal and slag removal mechanism of this utility model, ensure that the tower body 1 and the conical ash hopper 10 are firmly installed through the upper fixing ring 13 and the lower fixing ring 14, the water inlet pipe 32 is connected to the external high-pressure water source, the screw feeder 12 is in standby state, and during the deacidification operation, the purified gas is discharged through the gas outlet hood 34 and the gas outlet pipe 35, and the ash and slag fall into the conical ash hopper 10.
[0041] The automatic cleaning is activated periodically. The waterproof motor 2 drives the stirring shaft 20 to rotate. The cleaning scraper 21 scrapes off the ash residue from the inner wall of the conical ash hopper 10. The ash residue slides along the inclined inner wall into the vertical pipe 11. The screw feeder 12 starts to transport and discharge the ash residue. At the same time, the water ring 31 supplies water to the high-pressure vertical flushing nozzle 33. The water flow washes along the inner wall of the tower body 1 to remove impurities. The waterproof heat dissipation cover 22 protects the motor and is cleaned by the water flow.
[0042] After cleaning, turn off the waterproof motor 2 and the flushing system. The screw feeder 12 will empty the residual ash and slag. If maintenance is required, remove the conical ash hopper 10 to maintain the internal components and ensure stable operation next time.
