Problems solved by technology
The process belongs to high temperature, high humidity, high concentration, strong corrosion, and regular continuous discharge. According to the Environmental Protection Law, it must be purified before being discharged. However, the amount of acid mist collected by the conventional treatment method is not large, making the working environment harsh and the air heavily polluted

Embodiment Construction
[0021] Example. An acid mist treatment method, which is characterized in that: the acid mist in the pickling working tank is closed by blowing (that is, the principle of air curtain), and then the acid mist is absorbed and transported into a treatment tower, and then passed through the treatment tower for many times. After filtration, the acid components in the acid mist are separated and recovered, and finally discharged at high altitude after being adsorbed by activated carbon.
[0022] The multiple filtration method in the treatment tower is that the acid mist is first sprayed with water mist three times, and then filtered by a cleaning ball, so as to separate and recover the acidic components in the acid mist.
[0023] The suction air flow is greater than 3 times the blowing flow to achieve complete absorption of the acid mist.
[0024] The acid mist treatment device for realizing the above-mentioned acid mist treatment method, such as figure 1 As shown, it is characteri...

The invention discloses an acid mist treatment method and an acid mist treatment device. The acid mist treatment method comprises the steps of using a blower to seal up acid mist in an acid washing work tank, then absorbing the acid mist, delivering the acid mist to a treatment tower, filtering the acid mist for multiple times through the treatment tower, separating and recovering acidic components in the acid mist, finally adsorbing through activated carbon and discharging at a high altitude. The acid mist treatment method and the acid mist treatment device not only have a good acid mist collection effect, can keep a working environment good and can reduce air pollution, but also have a better purification effect and can further protect the environment.
Description
technical field [0001] The invention relates to an acid mist treatment method and device, in particular to an acid mist treatment method and device in the process of pickling a stainless steel pipe. Background technique [0002] Pickling is one of the most common methods of cleaning metal surfaces, whether it is low-magnification inspection of metal blanks or surface derusting of metal products such as strip steel. Pickling solutions generally include hot solutions of sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid and hydrofluoric acid. [0003] At present, the pickling of stainless steel pipe is the oxide skin treatment on the surface of stainless steel pipe, and the specific process is: stainless steel pipe-water washing-pickling-water washing-drying-finished product. This process belongs to high temperature, high humidity, high concentration, strong corrosion, and regular continuous discharge. According to the Environmental Protection Law, it must be puri...
