Description

Technical Field

[0001] This utility model belongs to a certain field, specifically, it relates to a high-pressure flash tank combined with a gasification scrubbing tower sewage discharge system. Background Technology

[0002] The scrubbing tower is a new type of high-efficiency waste gas treatment equipment that has been optimized and upgraded from the floating packing layer gas purifier in multiple dimensions. It has significant advantages in the field of industrial waste gas treatment, and is especially suitable for the purification pretreatment and dust removal of various industrial waste gases. When it is working, it allows the harmful components and dust particles in the waste gas to fully react or fuse with the scrubbing liquid through gas-liquid contact, so as to achieve efficient purification. Whether it is dusty waste gas generated by chemical, metallurgical, power and other industries, or industrial tail gas containing harmful substances such as acids and alkalis, the concentration of pollutants can be significantly reduced after treatment. Therefore, it has been widely and maturely applied in the field of industrial waste gas treatment.

[0003] However, when existing devices discharge wastewater, impurities at the bottom of the scrubbing tower cannot be completely discharged with the wastewater. The impurities will continue to accumulate, and the accumulated impurities will breed bacteria. This will not only weaken the purification effect, but also cause secondary pollution.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0023] like Figures 1 to 5As shown, a high-pressure flash tank combined with a gasification scrubbing tower sewage discharge system includes a base plate 1. A scrubbing tower body 2 is mounted on the upper surface of the base plate 1. The scrubbing tower body 2 is internally equipped with a scraping mechanism 3 and a moving mechanism 4. The scraping mechanism 3 includes a mounting frame 301. A sliding rod 302 is mounted inside the mounting frame 301. Two springs 304 are sleeved on the outer surface of the sliding rod 302. Two sliding sleeves 303 are slidably connected to the outer surface of the sliding rod 302. A slider 305 and a first mounting seat 306 are mounted on the outer surface of each sliding sleeve 303. A groove 307 is opened inside the mounting frame 301. The outer surface of each slider 305 is slidably connected to the inside of the groove 307. A scraper 309 is arranged above the mounting frame 301. A connecting rod 308 is rotatably connected to the inside of the first mounting seat. The outer surface of the scraper 309... The second mounting base 310 is installed, and the end of the connecting rod 308 away from the first mounting is rotatably connected to the inside of the second mounting base 310. The scraping mechanism 3 is based on the mounting frame 301, with the sliding rod 302 installed inside as the core support. Two springs 304 sleeved on the outer surface and two sliding sleeves 303 slidably connected form an elastic adjustment structure. The outer surface of each sliding sleeve 303 is connected to a slider 305 and the first mounting base 306 respectively. The slider 305 is embedded in the sliding groove 307 of the mounting frame 301 and can slide stably along the groove, providing guidance and constraint for the movement of the sliding sleeve 303. The continuous elastic force of the spring 304 ensures that the scraper 309 is always in close contact with the bottom of the washing tower body 2, so as to stably scrape off the attached impurities during the movement with the mounting frame 301, and achieve adaptive contact scraping.

[0024] like Figure 1 and Figure 4 As shown, a support plate 16 is installed on the right side of the washing tower body 2. The moving mechanism 4 includes a motor 401 mounted on the upper surface of the support plate 16. The output end of the motor 401 passes through the washing tower body 2 and is connected to a threaded rod 402. The end of the threaded rod 402 away from the motor 401 is rotatably connected to the inside of the washing tower body 2. A threaded sleeve 403 is threadedly connected to the outer surface of the threaded rod 402. A limit block 404 and a connecting block 405 are installed on the outer surface of the threaded sleeve 403. The bottom surface of the connecting block 405 is connected to the upper surface of the mounting bracket 301. The inside of the washing tower body 2... A baffle 406 is installed, and a limiting groove 407 is opened on the bottom surface of the baffle 406. The outer surface of the limiting block 404 is slidably connected to the inside of the limiting groove 407. The motor 401 drives the threaded rod 402 to rotate. With the cooperation of the limiting block 404 and the limiting groove 407, the threaded sleeve 403 is limited. It is connected to the mounting frame 301 of the scraping mechanism 3 through the connecting block 405. When the motor 401 drives the threaded rod 402 to rotate, the threaded sleeve 403 drives the mounting frame 301 to move synchronously, so that the scraper 309 of the scraping mechanism 3 moves with it in the tower to realize the scraping action.

[0025] like Figure 1 , Figure 2 and Figure 5 As shown, a sealing mechanism 5 is provided on the left side of the washing tower body 2. The sealing mechanism 5 includes an installation plate 503 installed on the left side of the washing tower body 2. An electric push rod 502 is installed on the bottom surface of the installation plate 503. A connecting plate 501 is installed on the output end of the electric push rod 502. A sealing plate 504 is connected to the bottom surface of the connecting plate 501. A fixing plate 7 is installed on the right side of the washing tower body 2. A water tank 6 is installed on the upper surface of the bottom plate 1. A water pump 8 is installed on the upper surface of the fixing plate 7. The outlet of the water tank 6 is connected to the input end of the water pump 8 through a pipe. The output end of the water pump 8 is connected to a water supply pipe 9. The end of the water supply pipe 9 away from the water pump 8 passes through the washing tower body 2 and is connected to a connecting pipe 10. A sealing plate 504 is installed on the outer surface of the connecting pipe 10. The washing tower has multiple nozzles. Inside the main body 2 of the washing tower, there is a demisting layer 13 and two fixed frames 11. The two fixed frames 11 are connected to a filter plate 12. The outer surface of the main body 2 of the washing tower is connected to a conveying pipe 14. A controller 15 is installed on the outer surface of the main body 2 of the washing tower. The electric push rod 502 of the sealing mechanism 5 controls the lifting and lowering of the sealing plate 504 to realize the opening and closing of the drain port. The water pump 8 draws water from the water tank 6 and washes the inside of the tower through the nozzles via the water supply pipe 9 and the connecting pipe 10. The filter plate 12 filters impurities, the demisting layer 13 removes water mist, and the exhaust gas enters through the conveying pipe 14. The controller 15 coordinates the various components with the moving mechanism 4 and the scraping mechanism 3 to complete the washing, filtering, and scraping. After that, the sewage is discharged from the drain port, ensuring the efficient operation of the washing tower.

[0026] Working principle: After the exhaust gas enters the main body 2 of the scrubbing tower through the conveying pipe 14, the controller 15 starts the water pump 8, which delivers water from the water tank 6 to the nozzles via the water supply pipe 9 and connecting pipe 10. The nozzles spray water to rinse the inside of the tower to remove internal impurities. The rinsed water is filtered by the filter plate 12 to remove some impurities, and finally passes through the demister layer 13 to remove water mist, completing the purification process. During sewage discharge, the controller 15 controls the electric push rod 502 of the sealing mechanism 5 to retract, which moves the connecting plate 501 and the sealing plate 504 upward, opening the sewage outlet and allowing some impurities to be discharged with the sewage. The impurities at the bottom will remain at the bottom of the scrubbing tower main body 2. The controller 15 starts the motor 401 to drive the threaded rod 402 to rotate. The threaded sleeve 403 moves smoothly under the cooperation of the limit block 404 and the limit groove 407 of the baffle 406. It drives the mounting frame 301 to move through the connecting block 405. In the scraping mechanism 3, the spring 304 on the slide rod 302 pushes the slide sleeve 303, so that the slider 305 slides in the slide groove 307 and drives the connecting rod 308 to adjust the angle, ensuring that the scraper 309 always fits against the bottom of the tower and moves with the mounting frame 301 to thoroughly scrape away the impurities at the bottom of the tower. After the sewage discharge is completed, the electric push rod 502 extends and drives the sealing plate 504 to reset, closing the sewage discharge port.
