[0002] Desulfurization towers convert sulfur dioxide in flue gas into harmless substances through chemical reactions or physical adsorption. Their core function is to meet environmental standards for industrial waste gas emissions, making them indispensable, especially in highly polluting industries such as coal-fired power plants, steel mills, and chemical plants.

[0003] According to the patent titled "A Wastewater Discharge Device for Power Plant Desulfurization Towers" (Patent Publication No.: CN114934572A, Patent Publication Date: 2022-08-23), the device includes a discharge assembly comprising a discharge pipe with connecting flanges at both ends, one of which connects to the discharge port of the desulfurization tower. A first regulating groove is provided through the side of the discharge pipe. An anti-clogging assembly includes an regulating ring located inside the discharge pipe, with a connecting shaft on one side of the regulating ring passing through the first regulating groove. The regulating ring has a shaft hole, and a rotating shaft is located inside the regulating ring, with one end passing through the shaft hole and the other end rotatably connected to the regulating ring. Because the wastewater from the desulfurization tower contains a large number of solid particles, to prevent pipe blockage during discharge, the anti-clogging assembly is driven by a motor to reciprocate and stir the inside of the discharge pipe, effectively preventing blockage. Furthermore, the drainage pipe is easy to install and disassemble, and the structure is ingenious.

[0004] Based on the aforementioned existing technology, current automatic wastewater discharge devices for desulfurization towers still have the following problems: desulfurization wastewater has a complex composition, containing high concentrations of impurities such as gypsum, dust, fly ash, and heavy metals. In a static or slowly flowing cylinder, these impurities easily precipitate, crystallize, and firmly adhere to the cylinder wall, forming a hard scale layer. Therefore, this utility model provides an automatic wastewater discharge device for desulfurization towers. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] An automatic wastewater discharge device for a desulfurization tower includes a discharge mechanism 1, and a cleaning mechanism 2 is installed inside the discharge mechanism 1 for cleaning the scale on the cylinder wall. The cleaning mechanism 2 includes:

[0027] Vibration unit 21 is disposed inside sewage discharge mechanism 1 and is used to make rotating unit 22 rotate inside sewage discharge mechanism 1;

[0028] The rotating unit 22, located above the vibration unit 21, includes a housing 221. A drive plate 224 is slidably installed inside the housing 221, and the drive plate 224 has several inclined slots 225 arranged in a linear array inside. Several connecting rods 226 are slidably installed through one side of the housing 221, and a sliding column 227 is installed through the inner end of the connecting rod 226. The sliding column 227 is located inside the inclined slot 225 and slides accordingly. A hammer head 228 is fixedly installed on the outer end of the connecting rod 226. The drive plate 224 is driven up and down to reciprocate through the drive assembly 3, so that the sliding column 227 slides inside the inclined slot 225. The connecting rods 226 push and pull the hammer head 228 to make it hit the dirt on the cylinder wall, thereby cleaning the dirt on the cylinder wall.

[0029] In this embodiment, a T-shaped seat plate 222 is fixedly installed inside the vibration unit 21, and a sliding seat 223 is slidably installed on the protrusion of the T-shaped seat plate 222. The drive plate 224 is fixedly installed on one side of the sliding seat 223. The movement of the drive plate 224 is limited by the sliding seat 223 sliding on the T-shaped seat plate 222.

[0030] The T-shaped base plate 222 fixedly installed inside the vibration unit 21 and the sliding seat 223 slidably installed on its protrusion achieve precise limiting of the movement path of the drive plate 224. This ensures that the drive plate 224 remains stable during reciprocating motion and avoids deviation or jamming during operation.

[0031] In this embodiment, the drive assembly 3 includes a linkage rod 31 fixedly installed at the bottom of the drive plate 224, a micro motor 32 fixedly installed on one side of the T-shaped base plate 222, and the output end of the micro motor 32 passes through the T-shaped base plate 222 and is fixedly installed on a turntable 33. A linkage column 34 is fixedly installed on one side of the turntable 33 near the edge, and the linkage column 34 is located inside the linkage rod 31 for sliding adaptation.

[0032] The turntable 33, driven by the micro motor 32 and fixedly mounted with the linkage column 34, cleverly converts the rotational motion of the micro motor 32 into the smooth up-and-down reciprocating linear motion of the drive plate 224 by utilizing the adaptive sliding of the linkage column 34 inside the linkage rod 31.

[0033] In this embodiment, a scraper 229 is fixedly installed on one side of the housing 221 for cleaning residual dirt on the cylinder wall.

[0034] A scraper 229 is fixedly installed on one side of the housing 221, making it an important component of the cleaning mechanism 2. The scraper 229 is designed to scrape and clean residual dirt that still adheres to the inner wall of the cylinder 11 after being vibrated and impacted by the hammer 228.

[0035] In this embodiment, the sewage discharge mechanism 1 includes a cylinder 11, a base 12 is provided below the cylinder 11, a liquid impact plate 114 is fixedly installed on the top of the cylinder 11 via a flange seat 13, a sampling tube 15 is fixedly installed on the top of the inspection cover 14, and a connecting threaded ball valve 16 is provided in the middle of the sampling tube 15. A replacement pipe 17 is fixedly installed on the top of the inspection cover 14, and a replacement flange ball valve 18 is provided in the middle of the replacement pipe 17. A connecting pipe 1 is installed through the left side of the inside of the cylinder 11. 9. A magnetic automatic control valve 111 is provided on the inner surface of the connecting pipe 19 inside the cylinder 11, and a shut-off valve 110 is provided on the outer surface of the connecting pipe 19 outside the cylinder 11. A liquid impact plate 114 is provided on the inner right side of the cylinder 11, and an inlet pipe 115 is provided on the right side of the cylinder 11. A drain pipe 112 is fixedly installed on the left side of the cylinder 11, and a drain flange ball valve 113 is provided in the middle of the drain pipe 112. The left end of the connecting pipe 19 is fixedly connected to the drain pipe 112.

[0036] The liquid impact plate 114 installed on the flange seat 13 mitigates the impact of incoming water. The sampling tube 15 and replacement tube 17 installed on the maintenance top cover 14 facilitate daily water quality monitoring and maintenance operations. The magnetic automatic control valve 111 installed on the internal connecting pipe 19 automatically opens and closes according to the water level to achieve automatic sewage discharge, and connects with the sewage discharge pipe 112 to form an efficient sewage discharge path. This overall structural design optimizes the stability, automation level and maintainability of the device, meeting the needs of continuous and automatic sewage discharge in industrial sites.

[0037] In this embodiment, the rotating unit 22 includes a servo motor 211 fixedly installed at the bottom of the cylinder 11. The output end of the servo motor 211 passes through the cylinder 11 and is fixedly installed with a rotating rod 212. The servo motor 211 is fixedly installed at the top of one end of the rotating rod 212.

[0038] The servo motor 211 drives the rotating rod 212 that passes through the cylinder 11 to rotate through its output end, thereby driving the entire rotating unit 22 to perform circular motion. This allows the hammer head 228 and scraper 229 mounted on it to perform 360-degree cleaning around the inner wall of the cylinder 11 without dead angles, ensuring the comprehensiveness of the cleaning range and completely solving the problem of insufficient local cleaning.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] During operation, the sewage discharge device utilizes the principle of communicating vessels to discharge wastewater from the desulfurization tower into the cylinder 11 through the inlet pipe 115. The cylinder 11 is equipped with a magnetic automatic control valve 111. When the water level reaches a certain position, the magnetic automatic control valve 111 automatically opens, discharging the wastewater through the drain pipe 112. When the water level drops to a certain height, it automatically closes, repeating this cycle to achieve automatic sewage discharge. The inlet pipe of the magnetic automatic control valve 111 is always submerged in water, ensuring that the wastewater and gas within the device are always separated. When the magnetic automatic control valve 111 discharges water, it only discharges water, while the gas remains in the gas phase.

[0041] Then, when the device stops running, the micro motor 32 drives the turntable 33 to rotate. The turntable 33 drives the linkage column 34 to slide inside the linkage rod 31, causing the linkage rod 31 to move up and down reciprocally. The linkage rod 31 drives the drive plate 224 to move synchronously. When the drive plate 224 moves, the sliding column 227 slides inside the inclined groove 225. The inclined groove 225 causes the connecting slide rod 226 to move left and right reciprocally. The connecting slide rod 226 synchronously drives the scraper 229 to move. The scraper 229 hits the inside of the cylinder 11, causing the dirt adhering to the inner wall of the cylinder 11 to fall off. The servo motor 211 drives the rotating rod 212 to rotate. The rotating rod 212 drives the rotating unit 22 to rotate, thoroughly cleaning the inner wall of the cylinder 11. At the same time, the scraper 229 scrapes the inner wall of the cylinder 11 to clean the remaining dirt.
