Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, in particular to a spray tower for waste gas treatment. Background Art

[0002] As my country pays more and more attention to the ecological environment, some environmental protection equipment and processes are becoming more and more advanced. Spray towers, as one of the waste gas treatment methods, are mainly used in some chemical plants and steel mills. A large amount of waste gas is often emitted during production and processing. The emitted waste gas has a strong odor and pollutes the environment. Therefore, many companies use spray towers to purify harmful substances in the air during production.

[0003] However, currently existing spray towers directly use filter elements and nozzles to purify impurities in exhaust gas. Since the nozzles are fixed, the nozzles cannot spray water evenly, and the nozzles are easily blocked by impurities in the air, thereby affecting the spraying, resulting in insufficient exhaust gas treatment. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the utility model provides a spray tower for waste gas treatment which can spray water evenly and clean the spray head, thereby being able to more fully treat the waste gas.

[0007] Furthermore, it also includes a push rod, a limiter, a scraper and a return spring. Each of the spray pipes is slidably connected to a push rod, the push rod is made of iron, each of the spray pipes is fixedly connected to a limiter, the limiter is slidably connected to the push rod, the push rod is fixedly connected to a scraper, and a return spring is connected between the scraper and the push rod.

[0009] Furthermore, the adsorption magnet is provided with an inclined surface.

[0010] The utility model has the following advantages: 1. During waste gas treatment, the staff introduces waste gas into the air inlet pipe, and the waste gas enters the filter cartridge. The three filters will first filter the waste gas, and then water enters the spray pipe through the joint, and the water is sprayed out from the spray pipe. Then the staff starts the rotating component, and the rotating component will drive the spray pipe to rotate, so that the spray pipe can evenly spray water, thereby reducing impurities in the waste gas. Then the staff starts the fan, and the filtered waste gas enters the outlet pipe for discharge. When the waste gas treatment is completed, the staff stops introducing waste gas into the air inlet pipe and turns off the fan. Then the staff uses a water pump to extract the waste liquid at the bottom of the base through the air inlet pipe for treatment, which can facilitate the next waste gas treatment. Filtering first and then spraying can fully treat the waste gas.

[0011] 2. The rotation of the spray pipe will drive the push rod, limiter, scraper and reset spring to rotate.

[0019] Example 1: A spray tower for waste gas treatment, such as Figure 1-Figure 4 and Figure 6 As shown, it includes a base 1, a filter cartridge 2, an air inlet pipe 3, an air supply pipe 4, a fan 5, an air outlet pipe 6, a filter element 7 and a rotating water injection pipe 8. The top of the base 1 is connected to the filter cartridge 2 by bolts, the lower part of the filter cartridge 2 is connected to the air inlet pipe 3 by bolts, the air inlet pipe 3 is communicated with the filter cartridge 2, the top of the filter cartridge 2 is connected to the air supply pipe 4 by bolts, the air supply pipe 4 is communicated with the filter cartridge 2, the top of the base 1 is connected to the fan 5 by bolts, the air inlet of the fan 5 is connected to the air supply pipe 4 by bolts, the air outlet of the fan 5 is connected to the air outlet pipe 6 by bolts, three filter elements 7 are connected in the filter cartridge 2 by rivets, and a rotating water injection pipe 8 is rotatably connected to the air supply pipe 4.

[0020] It also includes a rotating component 9, a fixer 10, a joint 11 and a spray pipe 12. The filter cartridge 2 is fixedly connected to the rotating component 9, and the rotating component 9 is composed of a support frame, a motor, a worm gear and a worm. The filter cartridge 2 is connected to a support frame by bolts, and the top of the support frame is connected to the motor by bolts. The output shaft of the motor is connected to the worm by bolts. The rotating water injection pipe 8 is connected to a worm gear by bolts, and the worm gear is meshed with the worm. Two fixers 10 are connected to the air supply pipe 4 by rivets, and the two fixers 10 are rotatably connected to the rotating water injection pipe 8. The upper part of the rotating water injection pipe 8 is connected to a joint 11 by bolts, and the bottom of the rotating water injection pipe 8 is connected to a plurality of spray pipes 12 by rivets. Two of the spray pipes 12 form a group, and the two spray pipes 12 in each group are symmetrically arranged, and the spray pipe 12 is connected to the rotating water injection pipe 8.

[0021] During waste gas treatment, the staff introduces waste gas into the air inlet pipe 3, and the waste gas enters the filter cartridge 2. The waste gas entering the filter cartridge 2 rises slowly, and the rising waste gas is filtered through three filter screens. Then water enters the rotating water injection pipe 8 through the joint 11, and the water enters the spray pipe 12 through the rotating water injection pipe 8. The water is sprayed out from the spray pipe 12, and then the staff starts the rotating component 9. The rotating component 9 will drive the rotating water injection pipe 8 to rotate. The rotation of the rotating water injection pipe 8 will drive the spray pipe 12 to rotate, so that the spray pipe 12 can evenly spray water. The spray pipe 12 evenly sprays water to absorb impurities in the gas. Thereby reducing the impurities in the exhaust gas, the waste liquid containing impurities will drip to the bottom of the base 1, and when the filtered exhaust gas rises to the air pipe 4, the filtered exhaust gas will enter the air pipe 4, and then the staff will start the fan 5, and the filtered exhaust gas will enter the exhaust pipe 6 through the air pipe 4 to discharge the filtered exhaust gas. When the exhaust gas treatment is completed, the staff will stop introducing the exhaust gas into the air inlet pipe 3 and turn off the fan 5, and then the staff will use a water pump to extract the waste liquid at the bottom of the base 1 through the air inlet pipe 3 for treatment, which can facilitate the next exhaust gas treatment. Filtering first and then spraying can fully treat the exhaust gas.

[0022] Embodiment 2: Based on embodiment 1, Figure 3-Figure 6 As shown, it also includes a push rod 13, a limiter 14, a scraper 15 and a return spring 16. Each of the spray pipes 12 is slidably connected with a push rod 13, and the push rod 13 is made of iron. Each of the spray pipes 12 is connected with a limiter 14 by bolts, and the limiter 14 is slidably connected to the push rod 13.

Two adsorption magnets 18 are connected to the support plate 17 by bolts. The adsorption magnet 18 is provided with an inclined surface, and the adsorption magnet 18 will attract the spray pipe 12.

[0024] The rotation of the spray pipe 12 will drive the push rod 13, the limiter 14, the scraper 15 and the return spring 16 to rotate. When one group of push rods 13 rotates to the adsorption magnet 18, the adsorption magnet 18 will attract one group of push rods 13. One group of push rods 13 moves toward the adsorption magnet 18 to compress the return spring 16. The movement of one group of push rods 13 will drive the scraper 15 to move toward the adsorption magnet 18. When one group of push rods 13 rotates away from the adsorption magnet 18, the return spring 16 will reset. The reset of the return spring 16 drives one group of push rods 13 to reset. The reset of one group of push rods 13 drives the scraper 15 to reset. The movement of the scraper 15 can scrape off impurities on the spray pipe 12, so that the spray pipe 12 can spray water more evenly, thereby reducing impurities in the gas and more fully treating the exhaust gas.
