For the pickling tank, the inducer 2 can also change the gas distribution condition in the tank, improve the gas fluidity in the tank and prevent the enrichment of hydrogen.
In one embodiment, a demisting adsorbent layer 24 is disposed in the return air channel 22 of the inducer 2, so as to absorb acid mist/alkali mist in the return air. The defogging adsorbent layer 24 is preferably an SDG adsorbent or an activated carbon adsorbent.
Wherein there may be multiple return air inlets/channels 22 in the inducer 2 to increase throughput.
In the case that the strip steel cleaning tank is a pickling tank, a dehydrogenation adsorbent layer 25 is further disposed in the return air channel 22 of the inducer 2, and the dehydrogenation adsorbent layer 25 is located downstream of the demisting adsorbent layer 24. Based on the scheme, the hydrogen can be adsorbed in the inducer 2, the concentration of the hydrogen in the air supply jet flow is low, the concentration of the hydrogen in the tank can be effectively reduced, and the hydrogen control effect is obvious. The return air firstly passes through the demisting adsorbent layer 24 to adsorb acid mist, then enters the dehydrogenation adsorbent layer 25 to carry out hydrogen adsorption treatment, so that the process rationality is high, the hydrogen adsorption effect can be ensured, and the load of the dehydrogenation adsorbent layer 25 is reduced.

The air return opening and the air supply opening are both arranged on the induction box 28; the outlet side of the induction box 28 is provided with an air-feeding nozzle which faces into the tank 1 for feeding an air-feeding jet into the tank 1.
Wherein, preferably, the injection angle of the air supply nozzle is adjustable, which can improve the process flexibility.
In one embodiment, for a pickling tank, the supply air jet output by the supply air port takes at least one of the following forms:
(1) The air supply jet flow faces the hydrogen enrichment area and is used for driving the hydrogen in the tank to the exhaust outlet of the tank body 1, so that the fluidity of the hydrogen can be increased, and the hydrogen can be easily discharged out of the tank;
(2) The air supply jet flow faces the periphery of the hydrogen enrichment area and is used for forming a negative pressure suction effect on the hydrogen enrichment area, and the negative pressure effect is generated through the jet flow, so that hydrogen in the hydrogen enrichment area can be sucked, and the fluidity of the hydrogen is increased;
it can be seen that in this embodiment, the air supply power of the inducer 22 can further achieve the effect of hydrogen control, and can also save the exhaust energy consumption of the tank 1.

Or, the air supply jet flow output by the air supply opening faces the easy-leakage point of the tank body 1 and is used for driving the alkali mist in the tank away from the easy-leakage point, so that the leakage of the alkali mist can be further reduced. For example, the air supply jet flow is sprayed to the wringer roller/access door, so that the air curtain sealing effect can be achieved, and the sealing performance of the alkaline washing tank can be improved.
