Problems solved by technology

[0003] However, the existing washing towers have the problem of single structure and function. One tower can only spray one kind of chemical solution, and the exhaust gas often contains multiple pollutants and needs to be treated with multiple chemical solutions. In this way, the number of washing towers needs to be increased. The cost also increases accordingly, thus reducing the competitiveness of the product
The reason for these problems and shortcomings is mainly because the internal structure of the existing washing tower cannot be made too complicated, and different medicinal liquids cannot be effectively separated when washing with various medicinal liquids, and different medicinal liquids are mixed together. Will react and affect the treatment of exhaust gas

Embodiment 1

[0013] like figure 1 As shown, the present invention provides a dual-purpose exhaust gas scrubber, including a tower body, and the tower body is provided with a mist eliminator 6, a primary packing layer 5 and a secondary packing layer 3 sequentially from top to bottom. Three primary spraying devices 7 are arranged between the device 6 and the primary packing layer 5, and the three primary spraying devices 7 are uniformly arranged on the top of the primary packing layer 5 laterally, and the primary spraying devices 7 is fixed on the primary infusion tube 11, the primary infusion tube 11 is connected to the primary drug liquid pump 1 outside the tower, and three secondary Spraying device 8, the three secondary spraying devices 8 are arranged horizontally evenly above the secondary packing layer 3, the secondary spraying device 8 is fixed on the secondary infusion pipe 21, the secondary The infusion pipe 21 is connected with the secondary liquid medicine pump 2 positioned outsi...

Embodiment 2

[0015] Exhaust gas enters the tower body from the air inlet 9, and the secondary liquid medicine pump 2 is started to spray the liquid medicine in the secondary liquid medicine tank 22 into the secondary packing layer 3 through the secondary spraying device 8 through the secondary infusion pipe 21. The exhaust gas enters the secondary packing layer 3 and fully contacts and reacts with the chemical solution sprayed by the secondary spraying device 8 to remove a corresponding pollutant in the exhaust gas. To the secondary liquid medicine tank 22, the gas after the reaction rises from the opening 41 of the dividing plate 4 and the tower body to the primary packing layer 5, and starts the primary liquid medicine pump 1 to pump the liquid medicine in the primary liquid medicine tank 12. After the primary infusion pipe 11 is sprayed into the primary packing layer 5 by the primary spraying device 7, the gas enters the primary packing layer 5 and fully contacts and reacts with the medi...

Abstract

The invention discloses a dual-purpose waste gas scrubbing tower. The dual-purpose waste gas scrubbing tower comprises a tower body, and a demister, a primary filler layer and a secondary filler layer are sequentially arranged in the tower body from top to bottom. At least one primary spraying device is arranged between the demister and the primary filler layer and fixed to a primary liquid delivery pipe which is connected with a primary liquid agent pump outside the tower body. At least one secondary spraying device is arranged between the primary filler layer and the secondary filler layer and fixed to a secondary liquid delivery pipe. The dual-purpose waste gas scrubbing tower has advantages that simultaneous application of two liquid agents to waste gas treatment in the tower body is realized, two pollutants in waste gas can be treated at the same time, scrubbing tower amount in a comprehensive waste gas treatment process is evidently decreased, and accordingly floor area is reduced, pressure loss in gas delivery is reduced, operation cost is reduced, and treatment cost is reduced as well.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a dual-purpose exhaust gas washing tower. Background technique [0002] The scrubber is a kind of gas purification treatment equipment, which is widely used in the treatment of industrial waste gas purification and dust removal; the scrubber is mainly composed of a tower body, a spray system, a packing layer, and a defogging layer; the exhaust gas enters the tower body, from bottom to bottom Up to the packing layer, fully contact and react with the spray water of the spray system in the packing to remove pollutants, the washed gas enters the demister layer for demisting, completes gas-liquid separation, and the separated gas is discharged out of the tower for subsequent treatment , the liquid recycles into the water tank. [0003] However, the existing washing towers have the problem of single structure and function. One tower can only spray one kind of chemical solution,...
