Abstract
The utility model provides an acid mist absorption tower for handling spent acid, including the tower body, the inside a plurality of packing layers that are equipped with of tower body, the packing layer is including packing bearing board and filler, and the packing layer top is equipped with the spray thrower, be equipped with a plurality of baffling boards on the packing bearing board, the baffling board perpendicular to packs the bearing board and arranges, packs to set up in the baffling passageway that the baffling board constitutes. The utility model discloses well baffling board's use makes the time extension of acid mist in the filler, and the reaction is more thoroughly even. The utility model discloses the use of well multiaspect clean shot has disturbed the flow direction of acid mist, has avoided the direct exhaust condition of acid mist not reacting, and the shower head is difficult for blockking up under the striking effect of multiaspect clean shot.
Description
Technical Field
The invention relates to the field of waste acid treatment, in particular to an acid mist absorption tower for treating waste acid and waste alkali.
Background
In industrial production, a large amount of acidic waste liquid is often generated. The acidic waste liquid has great harm to industrial production equipment and environment, and the removal of the acidic waste liquid becomes a key subject along with the increasing requirements of China on energy conservation and emission reduction of enterprises. The acid mist spray tower is used for spraying and collecting acid mist contained in the gas, and ensuring that pollution-free gas is discharged from the top of the absorption tower. However, after the gas with the acid mist is blown to the absorption tower by the fan, the retention time of the acid mist in the absorption tower is short, the acid mist cannot be uniformly sprayed by the spray header, but can directly and vertically flee upwards from one position to the air outlet to be discharged, instead of being uniformly neutralized by spray water, so that the spraying effect of the spray tower is affected, the discharged gas still contains more harmful substances, and the environment is finally polluted. Still other acid mist is prone to scale on the tower wall and the spray headers after reaction in the absorption tower, resulting in spray header plugging.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to overcome the defects in the prior art and provide an absorption tower for treating waste acid.
The invention has the innovation points that the retention time of the acid mist in the absorption tower is long, the spray header is not easy to block, and the spraying is uniform.
The technical scheme is as follows: in order to achieve the above object, the present invention is specifically realized as follows: an acid mist absorption tower for treating waste acid comprises a tower body, wherein a plurality of packing layers are arranged inside the tower body, each packing layer comprises a packing bearing plate and packing, a sprayer is arranged above each packing layer, a plurality of baffle plates are arranged on each packing bearing plate, the baffle plates are perpendicular to the packing bearing plates and are arranged, and the packing is arranged in a baffle channel formed by the baffle plates. When the acid mist passes through the filler, the time of the acid mist in the filler can be prolonged through the baffling channel, so that the reaction is more thorough and uniform.
Further, the baffle plate is movably connected with the packing bearing plate. Scale can be formed after the acid mist reaction, and the baffle plate and the filler bearing plate are detached and cleaned in the aspect of movable connection.
Furthermore, a plurality of multi-surface hollow balls are arranged between the packing layer and the sprayer. The polyhedral hollow sphere moves up and down under the action of the acid mist in the rising process of the acid mist, on one hand, the flowing direction of the acid mist is disturbed, and the acid mist is not discharged from an air outlet by directly moving up and down from one position; and on the other hand, the tower wall and the spraying device are slightly impacted, scaling substances on the tower wall and the spraying head are easy to drop under the slight impact, and the spraying head is not easy to block.
Furthermore, the polyhedral hollow sphere is made of PE, PP, RPP, PVC, CPVC and PVDF. Has acid resistance and is not easy to corrode.
Further, the sprayer is spirally arranged, and the diameter of the sprayer is gradually reduced from top to bottom. Spraying is from a plurality of layers of distribution down, and the time of spraying prolongs relatively, and the diameter is from last to descending in proper order, guarantees that the spent acid can both be sprayed from horizontal or vertical each angle.
The invention has the beneficial effects that: compared with the prior art, the invention has the following advantages:
1. the baffle plate is used in the invention, so that the time of the acid mist in the filler is prolonged, and the reaction is more thorough and uniform.
2. The use of the multi-surface hollow spheres disturbs the flow direction of the acid mist, the condition that the acid mist is directly discharged without reaction is avoided, and the spray header is not easy to block under the impact action of the multi-surface hollow spheres.
Drawings
Fig. 1 is a schematic structural view of embodiment 1.
Detailed Description
Example 1: as shown in figure 1, the acid mist absorption tower for treating waste acid comprises a tower body 1, wherein a plurality of packing layers 2 are arranged inside the tower body 1, each packing layer 2 comprises a packing bearing plate 2.1 and a packing 2.2, a plurality of baffle plates 2.3 are arranged on each packing bearing plate 2.1, each baffle plate 2.3 is perpendicular to each packing bearing plate 2.1 and is movably connected with each packing bearing plate 2.1, and each packing 2.2 is arranged in a baffle channel formed by the baffle plates 2.3. Packing layer 2 top is equipped with sprayer 3, and sprayer 3 is the heliciform and arranges, and the diameter from last to descending in proper order, is equipped with still to be equipped with a plurality of multiaspect clean balls 4 between packing layer 2 and the sprayer 3, and the preparation material of multiaspect clean ball 4 is PE, PP, RPP, PVC, CPVC, PVDF.
Claims (5)
