Description

Technical Field

[0001] The utility model relates to the technical field of treatment devices, in particular to a treatment device for waste gas acid mist. Background Art

[0002] Acid mist waste gas is generated during pickling or waste acid treatment in factories. Since these waste gases cannot be discharged directly into the air, the conventional treatment method is to suck the generated waste gas into the purification tower through the air duct under the action of the fan, and react and absorb with the reagent in the tower. The waste gas that meets the standards after treatment in the purification tower can be discharged into the air. Under the current severe environmental protection situation, it is particularly important to meet the standards for waste gas discharge. The existing waste gas acid mist is usually treated with an alkaline solution to neutralize and convert it into harmless substances. However, during long-term use, the alkaline solution is prone to precipitation, thereby affecting the treatment effect of the waste gas acid mist; therefore, we propose a treatment device for waste gas acid mist to solve the above-mentioned problems.

[0012] Beneficial effects of the utility model:

[0013] 1. In the past, alkaline solution was usually used to neutralize and convert the waste gas acid mist into harmless substances. However, during long-term use, the alkaline solution is prone to precipitation, which affects the treatment effect of the waste gas acid mist. The difference is that the arc slider drives the fan blades along the annular groove and slides with the mounting ring sleeve through the drive of the driver, thereby forming wind force, bringing the waste gas acid mist into the tank through the air inlet pipe, and then pouring the alkaline solution into the water supply tank through the water inlet pipe, and then driven by the water pump, the alkaline solution enters the water outlet pipe from the water supply tank and enters the nozzle. During the spraying, the nozzle is driven by the driver to rotate and connect with the water outlet pipe through the connecting shaft to expand the spraying area of ​​the alkaline solution, thereby neutralizing the waste gas acid mist and the alkaline solution and converting them into harmless substances. During the neutralization process, the rotating column drives the stirring plate to rotate through the drive of the motor to avoid precipitation of the alkaline solution and affect the treatment effect of the waste gas acid mist. Then, the display panel can be used to understand in real time the neutralization reaction of the waste gas acid mist and the alkaline solution inside the tank and the conversion into harmless substances, so as to facilitate timely adjustment.

[0014] 2. When the waste gas acid mist is treated, open the valve and the waste gas acid mist enters the exhaust pipe. The treated waste gas acid mist is separated from water and gas through the dehumidification plate. The separated gas passes through the dehumidification plate and is tested by the air quality detector to see whether the detection structure meets the emission standards. If it does, the treated gas is discharged into the atmosphere by loosening the sealing cover, and the separated liquid flows out through the water outlet for collection and unified treatment. In the process of water and gas separation, the rotating shaft drives the support rod to rotate along the rotating ring sleeve through the drive of the driver, so that the cleaning strip cleans along the surface of the dehumidification plate to avoid long-term operation of the dehumidification plate and affecting its dehumidification performance.
