(4) description of drawings

Fig. 1 is apparatus of the present invention structural representation.

(5) specific embodiment

See Fig. 1, the present invention includes blower fan 1, exhaust gas absorption device, exhaust gas absorption device comprises waste gas absorption tower and accumulator tank, and blower fan 1 pipeline connects waste gas absorption tower, accumulator tank is connected with the waste gas absorption tower lower pipeline and is connected with blending device 3 pipelines, and blending device 3 is connected with pickling lines 4.Exhaust gas absorption device is provided with two covers among the present invention, is respectively one-level absorption plant and sponge oil unit; Wherein the one-level absorption plant comprises that one-level waste gas absorption tower 2,6,7, accumulator tanks of accumulator tank, 6,7 backs in parallel form closed circuits with one-level waste gas absorption tower 2; Sponge oil unit comprises secondary waste gas absorption tower 9, secondary recovery groove 10,11, and closed circuit is formed with secondary waste gas absorption tower 9 in secondary recovery groove 10,11 backs in parallel; Two cover exhaust gas absorption device are connected in series; One-level waste gas absorption tower 2 is connected with secondary waste gas absorption tower 9; Accumulator tank 6 and secondary recovery groove 10, an accumulator tank 7 and secondary recovery groove 11 is corresponding respectively is connected; Be separately installed with acidometer 5 in the accumulator tank 6,7, the accumulator tank 6,7 of one-level absorption plant also is connected with blending device 3 respectively; The waste gas absorption tower rear portion of secondary exhaust gas absorption device also is connected with gas-liquid separator 8; Gas-liquid separator 8 gas outlets connect into pickling lines 4, and its delivery port connects adapted tank 12; Adapted tank 12 is connected with the secondary recovery groove 10,11 of described secondary exhaust gas absorption device, and the arrow among the figure is represented the trend of waste gas.

Describe the course of work of the present invention below in conjunction with accompanying drawing: the acid mist gas that pickling lines 4 produces is inhaled into by blower fan 1 and carries out the absorption of cold water spray in the one-level waste gas absorption tower 1, the very fast formation acid solution soluble in water of acid mist gas also flows into an accumulator tank 6 (or 7), an accumulator tank 6,7 take turns and change jobs, the acidometer that is installed in the accumulator tank 6 (or 7) detects acid solution, when acid strength reaches 10%~15%, one time accumulator tank 6 is closed the feed liquor valve automatically and is opened the valve that is connected with blending device 3, it is that to be hybridly prepared into concentration be to carry back pickling lines continuation use by pipeline after 25% the acid solution for 30%~33% acid solution that acid solution enters blending device 3 and concentration, when acid strength is lower than 10%, one time accumulator tank 6 interior acid solutions are back in the one-level waste gas absorption tower 2 and absorb with acid mist gas once more as shower water, acid solution enters accumulator tank 6 and carries out concentration again and detect then, and concentration reaches 10%~15% o'clock acid solution and enters blending device; And this moment, an accumulator tank 7 carried out work, and 2 accumulator tanks 7 of acid solutions inflow that absorbed carry out the concentration detection of acid solution in the waste gas absorption tower, as accumulator tank 6 repetitive cycling job; The one-level exhaust gas absorption device reaches about 80% for the absorptivity of acid mist gas, absorb handling acid mist gas enters the secondary waste gas absorption tower that is connected with one-level waste gas absorption tower 2 and carries out secondary spraying and absorb, its circulation absorption process is identical with the one-level exhaust gas absorption device, because the systemic acid mist gas flow of secondary waste gas absorption tower is few, acid strength after it absorbs through spray is lower, when its concentration reaches 2%~3% in the secondary recovery groove 10 (or 11), accumulator tank feed liquor valve cuts out acid solution automatically and enters an accumulator tank 6 (or 7) that is attached thereto, mixes with the acid solution in the accumulator tank 6 (or 7) and to carry out concentration detection, if concentration reaches 10%~15% then be admitted to blending device 3 and be mixed, if concentration is lower than 10% then be back to the spray that waste gas absorption tower 2 enters once more and absorb; The acid mist gas that in secondary waste gas absorption tower 9, does not also absorb fully, can enter the gas-liquid separator 8 that is attached thereto and carry out last separate absorbent, isolated air is sent into pickling lines via air outlet, can strengthen the flowability of workshop air, improve the quality of workshop air, acid solution after the separate absorbent enters adapted tank 12 through delivery port, enter the secondary recovery groove 10 (or 11) that is connected with adapted tank 12 again, carry out the concentration detection after mixing with the acid solution in the secondary recovery groove 10 (or 11), if concentration reaches 2%~3%, then acid solution is sent in the accumulator tank 6 (or 7), if concentration is lower than 2% then be back in the secondary waste gas absorption tower as spray liquid and continue to absorb.The above course of work moves in circles.

Apparatus of the present invention mainly can be handled HCL, HF, H 2SO 4, NaOH, H 2Water-soluble gas such as S according to different gas, adopt different absorbents.
