[0026] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please refer to Figures 1 to 2 This utility model provides an acid mist treatment device based on a steel pipe pickling production line, including a sealed room 1, a pickling tank 2 and a top suction duct 3;

[0028] The pickling tank 2 is set inside the sealed room 1. The pickling tank 2 includes a tank body 21 and a plurality of suction hoods 22 set on both sides of the tank body 21. Each suction hood 22 is connected to a suction pipe 23, and the suction pipe 23 is connected to a first anti-corrosion fan.

[0029] The top air intake duct 3 is installed on the top of the sealed room 1 and is located directly above the trough 21;

[0030] The suction hoods 22 on both sides of the pickling tank 2 can firstly adsorb most of the acid mist, and a small amount of rising acid mist can also be collected by the top suction duct 3. This application not only has low energy consumption, but also can effectively recover acid mist.

[0031] During use, the acid mist inside the sealed room 1 is collected simultaneously by the top suction duct 3 arranged at the top and the suction hood 22 on the side of the pickling tank 2, so that the inside of the sealed room 1 is always kept at a slight negative pressure, effectively collecting the acid mist, effectively preventing the acid mist from escaping, ensuring that the pickling workshop meets environmental protection requirements, and the collected acid mist is transported to the waste gas treatment tower 4, where it is purified and then discharged.

[0032] In this embodiment, the top suction duct 3 is connected in sequence to the exhaust gas treatment tower 4 and the second anti-corrosion fan 5. The exhaust gas treatment tower 4 is used to purify the acid mist.

[0033] In this embodiment, the air inlet of the suction hood 22 is located on the wall of the groove 21.

[0034] In this embodiment, a level gauge and a thermometer are installed in the tank 21 to obtain the temperature and level of the acid solution in the pickling tank 2.

[0035] In this embodiment, the suction area of ​​the top suction duct 3 coincides with the top opening area of ​​the pickling tank 2.

[0036] In this embodiment, a load-bearing pad is provided at the bottom of the trough 21.

[0037] The working principle of this utility model is as follows:

[0038] The acid mist inside the sealed room 1 is collected simultaneously by the top suction duct 3 arranged at the top and the suction hood 22 on the side of the pickling tank 2. The sealed room 1 is always kept at a slight negative pressure, which effectively collects the acid mist, prevents the acid mist from escaping, and ensures that the pickling workshop meets the environmental protection requirements. The collected acid mist is transported to the waste gas treatment tower 4 and discharged after meeting the comprehensive emission standards for air pollutants.
