Waste acid and sludge recycling cooperative treatment system

Abstract

The invention provides waste acid and sludge recycling cooperative treatment equipment. The equipment comprises a supporting unit; the top of the supporting unit is connected with the tower body; the transmission unit is rotationally arranged in the tower body; a transmission unit is arranged in the center of the mass transfer adjusting unit; the demisting unit is arranged at the top end of the mass transfer adjusting unit. Stacked fillers are quantitatively adjusted, so that the fillers at the top can be fully contacted with spraying water under mixing and stirring, the contact area of gas-liquid mass transfer is increased, the fillers at the bottom are pushed and overturned, the blockage of the fillers caused by unidirectional contact is reduced, a small amount of the fillers at the bottom are removed during pushing, and the blockage of the fillers at the bottom is reduced. And the top-layer filler can iterate the bottom-layer filler, so that the stacked filler can comprehensively carry out gas-liquid two-phase mass transfer, and the waste gas purification effect is improved.

Description

technical field [0001] The invention relates to the field of waste treatment, in particular to a waste acid and sludge resource co-processing system. Background technique [0002] In the process of industrialization and informatization, various industrial products will be produced, and in the steps of casting and pickling of industrial products, waste acid and iron-containing sludge will be associated with waste acid and iron-containing sludge. The co-processing of waste acid and iron-containing sludge will reuse waste acid and iron-containing sludge, thereby reducing the waste of resources. In the co-processing of waste acid and iron-containing sludge, waste acid and iron-containing sludge will be recycled. The waste gas produced by the sludge reaction is treated. In this process, a spray tower needs to be used. Through the purification of the spray tower, the waste gas can meet the emission standard.

AI Technical Summary

Problems solved by technology

[0005] 1. In the process of treating exhaust gas, the filler will be accumulated in the filler layer, and the liquid will be sprayed on the surface of the filler during the spraying of the sprinkler head, so that the gas phase of the exhaust gas and the liquid phase of the spray water will be in the filler layer. The reaction is carried out in the filler, but the liquid will not be in sufficient contact with the filler of the filler layer during the spraying process, resulting in less contact between the liquid phase and the gas phase, which in turn reduces the efficiency of gas-liquid two-phase mass transfer, resulting in poor purification effect of exhaust gas ;

[0006] 2. During the mass transfer and exchange of the packing, the packing at the bottom of the packing layer has the most contact with the rising exhaust gas. Long-term contact with the exhaust gas will cause the plugging and consumption of the bottom packing to be greater than that of the top packing, resulting in a decline in the mass transfer effect of the liquid and gas phases. ;

[0007] 3. During the mass transfer process, the exhaust gas will move upwards in the form of gas-liquid phase, so as to contact the demister at the top of the spray tower. The existing demister is in use, and the internal path of the equipment is fixed, so no It is convenient for the rapid cleaning of the liquid accumulated on the inner wall of the demister and the elimination of the mist;

[0008] In summary, the above problems will affect the purification and emission of waste gas in the process of waste acid and sludge synergistic treatment
