Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas desulfurization technology, specifically to a waste gas desulfurization and purification device. Background Technology
[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life. In particular, chemical plants, steel mills, pharmaceutical factories, coking plants, and oil refineries emit waste gas with strong odors, seriously polluting the environment and affecting human health. Desulfurization of waste gas can effectively reduce sulfur dioxide emissions and mitigate the negative impact on the environment and ecology.
[0003] Existing waste gas desulfurization and purification equipment cannot effectively reduce the temperature of waste gas due to its high temperature, thus affecting the desulfurization effect. In addition, after filtering the dust in the waste gas, the dust on the surface of the filter screen cannot be cleaned in time, which often causes blockage, affects filtration, and increases the cleaning burden on the staff.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0017] Please see Figures 1 to 3 This utility model provides a technical solution: a waste gas desulfurization and purification device, including an inlet pipe 1, a filter box 2 installed on one side of the inlet pipe 1 to filter dust inside the waste gas for subsequent desulfurization, a top plate 3 installed on the top of the filter box 2, an outer shell 4 installed on the outer wall of the filter box 2 near the inlet pipe 1, a drive motor 6 installed inside the outer shell 4, a first rotating shaft 7 installed on one side of the drive motor 6, a transmission belt 8 sleeved on the outer wall of the first rotating shaft 7, a rotating rod 9 installed on the inner wall of the transmission belt 8, a ball bearing 10 installed on the outer wall of the rotating rod 9, a support rod 11 fixedly connected to the bottom of the ball bearing 10, a cleaning brush 12 installed at one end of the rotating rod 9 to clean the dust adhering to the surface of the filter screen 14 while filtering the waste gas, to prevent dust from clogging the filter screen 14 and affecting its use, and a top plate 3 fixed at the bottom. The filter box 2 is connected by a buckle 13, and a filter screen 14 is installed on the inner wall of the buckle 13. A discharge port 15 is installed at the bottom of the filter box 2, and a recovery box 16 is installed at the bottom of the discharge port 15. A conveying pipe 17 is installed on the other side of the filter box 2. A reaction box 18 is installed at one end of the conveying pipe 17. An air outlet 19 is installed at the top of the reaction box 18. A water storage tank 20 is installed on the outer wall of the reaction box 18 away from the conveying pipe 17. A water supply pipe 21 is installed at the top of the water storage tank 20, and a nozzle 22 is installed at the bottom of the water supply pipe 21. A second rotating shaft 23 is installed inside the reaction box 18, and a stirring rod 24 is installed on the outer wall of the second rotating shaft 23 to fully mix sulfur dioxide with alkaline liquid, so as to facilitate its subsequent precipitation and recover sulfur resources. A water pump 25 is installed inside the water storage tank 20, and a discharge pipe 26 is installed at the bottom of the reaction box 18.
[0018] The reaction chamber 18 has a drive motor 6 on the back, the water tank 20 has an inlet on the top near the water pipe 21, and the water tank 20 has an observation window on the front. This allows for rapid and thorough mixing of the sulfur dioxide and alkaline liquid mixture, while also allowing the user to easily check the remaining contents of the water tank 20.
[0019] Among them, the buckle 13 has a concave shape, and there are two sets of buckles 13. The side of the buckle 13 near the discharge port 15 is tilted at a 45° angle, so that the dust can fall into the discharge port 15 for easy cleaning.
[0020] Both the filter box 2 and the reaction box 18 are equipped with a base 5 at the bottom, and the base 5 is equipped with an anti-slip pad to improve the overall stability of the device.
[0021] The water pump 25, water pipe 21, and nozzle 22 constitute the liquid delivery device. The liquid delivery device works in conjunction with the stirring rod 24 to enable rapid reaction, facilitate subsequent precipitation, and recover and utilize sulfur resources.
[0022] The air outlet of the delivery pipe 17 is located directly below the nozzle 22, and the reaction chamber 18 has an inner cavity with a frustum-shaped bottom.
[0023] Specifically, during use, exhaust gas enters the filter box 2 through the inlet pipe 1 and is filtered by the filter screen 14 to remove dust. The filtered exhaust gas then enters the reaction box 18 through the conveying pipe 17. While the filter screen 14 is filtering, to prevent dust from clogging it, the drive motor 6 controls the first rotating shaft 7 to rotate, which in turn drives the rotating rod 9 through the transmission belt 8. This causes the cleaning brush 12 to clean the dust from the surface of the filter screen 14. The cleaned dust enters the recovery box 16 through the discharge port 15 for recycling, reducing the burden of manual cleaning for staff. At the same time, the water pump 25 transports the alkaline liquid from the water tank 20 through the water pipe 21 and sprays it out through the nozzle 22, allowing the alkaline liquid to react with the sulfur dioxide gas inside the exhaust gas. The mixture accumulates in the reaction box 18, and then the drive motor 6 controls the second rotating shaft 23 to rotate, causing the stirring rod 24 to quickly and thoroughly mix the alkaline liquid and the sulfur dioxide reaction solution. After mixing, the mixture is discharged through the discharge pipe 26 for sedimentation, facilitating the recovery of sulfur resources, reducing waste, and avoiding environmental pollution.
