Description

Technical Field

[0001] The utility model relates to the technical field of galvanizing gas treatment, in particular to a galvanizing recovery and purification acid mist washing tower with a recycling effect. Background Art

[0002] Galvanizing gas is mainly produced by evaporating zinc liquid, which contains zinc vapor. Zinc vapor will have a certain impact on the human respiratory system, digestive system, nervous system, etc. Short-term exposure to galvanizing gas may cause mild symptoms such as headache, dizziness, nausea, etc. Further exposure may cause serious consequences such as pulmonary edema and liver damage. Gas purification equipment is required to meet its final emission standards.

[0003] The scrubber is a new type of gas purification equipment. It is improved on the basis of the floating packing layer gas purifier and is widely used in pre-treatment of industrial waste gas purification, dust removal, etc. The scrubber is usually injected into the scrubber. In practical applications, the scrubber is usually injected into the scrubber. The scrubber is evenly sprayed and dropped to the bottom of the tower by the spraying device, and then transported to the top of the tower by the circulating pump to form a cycle. The scrubber is evenly sprayed and dropped to the bottom of the tower by the spraying device. The waste gas is introduced into the scrubber from the bottom of the tower, and then floats upward and contacts with the scrubber. During the contact process, pollutants such as particles and acid gas in the waste gas are exchanged with the scrubber and remain in the scrubber. The purified gas that has been free of pollutants is finally discharged into the atmosphere through the top of the tower.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. Fillers are required for purification treatment in the washing tower, but the fillers need to be taken out for treatment. However, due to the structure of the tower body, it is inconvenient to take out the fillers and external material removal components are required; 2. Most fillers are statically placed when treating exhaust gas, and the positions of many spray components are not reasonable. When the washing liquid reaches the bottom of the washing tower during the spraying process, the concentration of pollutants it contains is already very high because it has treated the gas above. As a result, the washing liquid reaching the bottom of the washing tower cannot absorb more pollutants in the exhaust gas, thereby affecting the effect of removing pollutants in the exhaust gas.

The processing device 2 is a processing unit inside the washing tower, which contains a control program and a sensor unit. The medium containing pollutants in the medium will be processed and then diverted through the pipeline and discharged as wastewater, while the remaining medium can be returned to the washing liquid pool 10 through the pipeline for recycling. While the exhaust gas is rising, the servo motor 12 drives the cam 7 under the transmission structure of the array sprocket assembly 11. 04 rotate synchronously. When one side of the cam 704 rotates to the bottom of the movable bracket 703 during rotation, the movable bracket 703 with a movable structure will slide upward inside the slide groove 701. The rotating structure of the cam 704 is used to realize the purpose of the movable bracket 703 driving the top stuffing box 8 to lift and reciprocate. The motion structure of the top stuffing box 8 changes the motion direction of the airflow when passing through it, so that the exhaust gas is fully in contact with the internal stuffing. The adsorption effect is further improved by the motion structure. The gas separated from the pollutants is in an upward state in the tower body 1. When it rises to the discharge port 4, the sensor unit inside it detects that the gas does not contain galvanized substances.
