Description

Technical Field

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

[0002] The waste gas treatment spray tower is a common waste gas treatment equipment. It is usually installed near the chimney or waste gas outlet of industrial enterprises to achieve the purpose of cleaning the environment, efficiently utilizing resources and protecting health. When the waste gas treatment spray tower is used, sodium hydroxide absorption liquid is usually used to remove harmful components in the waste gas.

[0003] When the existing exhaust gas treatment spray tower is in use, the sodium hydroxide solution is circulated through the circulation device, thereby reducing the use cost of the device. However, in actual use, the exhaust gas in the chimney will carry impurities such as dust. After the exhaust gas is filtered, the impurities will adhere to the filter. After long-term use, the impurities on the filter will fall due to gravity, which will cause the liquid inlet pipe of the circulation device to be blocked, requiring the operator to stop the machine for cleaning. In addition, since the filter is installed inside the device and the installation position is high, it is not convenient for the operator to clean it, resulting in low cleaning efficiency of the device, and thus lacking a certain degree of practicality.

[0029] When ready for use, the spray tower body 11 is placed in a designated position, and the operator passes the exhaust gas into the spray tower body 11 through the air inlet pipe 12. Then, the operator passes the sodium hydroxide solution into the atomizer 22 through the circulation mechanism 21, and then sprays it out through the nozzle 23 to contact the exhaust gas and treat the exhaust gas. Then, the exhaust gas moves upward and is filtered through the filter screen 15. At the same time, the atomized sodium hydroxide is sprayed out from the nozzle 23 and passes through the filter screen 15. The impurities attached to the filter screen 15 contact with the sodium hydroxide and mix with it. The gravity increases and then falls on the filter screen 27. At the same time, when the device is used, the operator connects the internal power supply of the vibration motor 25 and turns on the vibration motor 25. The vibration motor 25 drives the filter screen 15 to vibrate and enhances the vibration effect through the spring 26 on the fixed plate 24, so that the impurities on the filter screen 15 fall off in one step, so that the operator does not need to clean the filter screen 15, but only needs to clean the impurities on the filter screen 27 The sodium hydroxide solution in the liquid storage tank 212 can be pumped into the liquid outlet pipe 214 and sprayed out through the nozzle 23. At the same time, the water pump 213 can pump back the sodium hydroxide solution flowing to the inner bottom of the spray tower body 11 through the liquid inlet pipe 215, so as to recycle the sodium hydroxide solution. When the solution is circulated, the filter screen 27 is used to prevent impurities from falling into the liquid inlet pipe 215. After use, the operator turns off the water pump 213 and opens the valve of the liquid discharge pipe 14 to discharge the sodium hydroxide solution from the device, reducing the number of shutdown maintenance times of the device, thereby improving the efficiency of the device in treating waste gas; each fixed plate 24 is provided with a telescopic shell 6, and the spring 26 drives the telescopic shell 6 to retract at the same time when it is retracted. The telescopic shell 6 can cover the spring 26 inside, thereby preventing the solution from corroding the spring 26 after long-term use, thereby improving the stability of the device.

[0033] After use, the operator connects the internal power supply of the electric push rod 33 in the installation box 32, and turns on the electric push rod 33, so that the output end of the electric push rod 33 drives the scraper 34 to scrape the impurities on the filter screen 27 into the collection box 31 for collection, so that the operator only needs to open the bottom valve of the collection box 31 to collect the impurities, and there is no need to manually clean the filter screen 27, thereby improving the convenience of the device; the top of the installation box 32 is provided with an inclined surface, so that when the impurities on the filter screen 15 fall to the top of the installation box 32, the impurities will fall onto the filter screen 27 along the inclined surface, preventing the impurities from remaining for a long time and causing bacteria to grow, thereby improving the convenience of the installation. The safety of the device is improved; a protective shell 5 is fixedly connected to the bottom of the filter 15, and the protective shell 5 can completely cover the vibration motor 25 to prevent the vibration motor 25 from being used in an environment with high humidity for a long time, resulting in poor contact of the internal water supply, thereby improving the stability of the device; a guide shell 4 is fixedly connected to the inner wall of the spray tower body 11, so that the used solution can completely flow out of the device through the guide shell 4, preventing a large amount of used solution from remaining inside, causing the used solution to re-enter the circulation mechanism 21 when the device is used again, resulting in a decrease in the treatment efficiency of the device, thereby improving the stability of the exhaust gas treatment of the device.
