Background technique

The spray tower exists as a treatment equipment for environmental protection waste gas treatment. During feed processing, the waste gas and dust are usually treated with the help of the spray tower.

Among them, after searching, it was found that there is a patent number CN202022272386.5, which discloses a spray tower for waste gas treatment, including a spray tower, a filter structure and a spray filter structure, a spray tower, and its outer arc surface. There is a smoke inlet pipe at the smoke port, which meets the maximum utilization of resources and can be used repeatedly. When there are too many impurities filtered in the filter box, the opening at the lower end of the outer arc surface of the spray tower is hinged with a box The upper surface of the door and the orifice plate is slidably connected to the filter box through the chute. The staff only need to open the door, then pull out the filter box through the handle, and then replace the new filter box to filter again, so that the staff can operate It is more convenient and quicker to mix and filter a large number of harmful substances in the exhaust gas, and then the filtered gas will pass through the sponge layer and the activated carbon layer. The sponge layer can simply dehumidify the air containing moisture, and the activated carbon layer can absorb pungent The substance is finally discharged from the gas outlet at the upper end of the protective cover, which meets the needs of the spray tower exhaust gas treatment, reduces the workload of the staff, and ensures that the discharged gas will not pollute the surrounding environment.

However, after research, it is found that the device does not have a structure for pretreatment and suction of the smoke in the exhaust gas. It is tightly filtered through the filter box and removed by water spraying. There will still be some fine dust that will be discharged from the filter box with the airflow. Possibly, and the nozzle is constantly fixed, and the spraying range is limited, so that the dust removal is not thorough enough. In addition, it is far from enough to absorb the irritating odor in the waste gas only through activated carbon. During the feed processing process, there will be more ammonia in the waste gas Such as alkaline gas and acid gas such as hydrogen sulfide, the device does not have a structure to neutralize the alkaline gas and acid gas, so that these harmful gases are discharged into the air and pollute the air, so a new device is provided to solve this problem.
