Preferably, because the absorption efficiency of common distilled water to acid mist is lower, in order to improve the absorption efficiency of neutralization liquid in spray tower 4 to acid mist in waste gas in the above-mentioned process, the neutralization liquid tank is filled with alkaline neutralization liquid, when the alkaline neutralization liquid is sprayed onto tail gas with acid mist, part of acid mist is dissolved in the neutralization liquid, when the alkaline in the neutralization liquid is neutralized by acid mist, part of acid mist is continuously dissolved in water until the upper limit of dissolution, compared with common distilled water, the alkaline neutralization liquid in unit volume can absorb more acid mist, the spray tower 4 is improved, only spray tower 4 which actually plays the role of acid mist absorption in the above-mentioned process, the absorption means is single, and in order to further improve the absorption effect to acid mist, the utility model further comprises an electrostatic absorption component 3, the gas inlet end and the gas outlet end of the electrostatic absorption component 2 are respectively connected with waste gas collection component 1 and spray tower 4, the electrostatic absorption assembly 2 comprises a shell 21, a control module 22, a positive electrode tube 23 and a negative electrode tube 24, wherein the input end and the output end of the shell 21 are respectively connected with the waste gas collection assembly 1 and the adsorption assembly 3, the positive electrode tube 23 and the negative electrode tube 24 are arranged in the shell 21, the control module 22 is electrically connected with the positive electrode tube 23 and the negative electrode tube 24 and forms a circuit, the control module 22 is used for supplying high-voltage direct current to the two electrode tubes, in the embodiment, the control module 22 at least comprises a control circuit, an alternating current-direct current converter and a transformer, the converter is started under the control of the control module 22 and supplies alternating current to the transformer after rectification and filtration, the transformer supplies the direct current to the positive electrode tube 23 and the negative electrode tube 24 after boosting the direct current, and then a high-voltage electrostatic field is formed between the positive electrode tube 23 and the negative electrode tube 24, in this embodiment, the two electrode tubes are respectively disposed at two sides of the air flowing space in the housing 21, and the axial directions of the two electrode tubes are perpendicular to the ground, at this time, the electrostatic field coincides with the air flowing space, when the waste gas of the cobalt production device flows into the housing 21 of the electrostatic absorption assembly 2 from the waste gas collecting assembly 1, the waste gas passes through the electrostatic field between the two electrode tubes, at this time, the negative electrode tube 24 continuously emits electrons, the gas passing through the electrode tubes is ionized into dust and acid mist particles in the positive and negative ion waste gas, and the dust and acid mist particles in the waste gas are charged together, because the electric field has adsorption or repulsion effect on charged objects, the dust and acid mist particles continuously move to the positive electrode tube 23 or the negative electrode tube 24 until the acid mist particles adsorbed on one of the electrode tubes lose charges, then flow down along the wall of the electrode tube perpendicular to the ground, and the residual gas continues to the air outlet end of the housing 21 without being affected by the electric field, thereby completing the separation of the acid mist or dust and the rest of the waste gas, and the electrostatic absorption assembly 2 is disposed at the upstream of the spray tower 4, so that the whole absorption device absorbs more acid mist and improves the absorption effect.
Because above-mentioned static absorbing device mainly relies on adsorbing charged acid mist particle to the electrode pipe in the absorption process of acid mist, the acid mist particle has probability and can't leave along the pipe wall and stay on the pipe wall after adsorbing, can have more acid mist particle to adhere to on the electrode pipe after long-term absorption, cause corrosive damage to the electrode pipe, in order to avoid the emergence of this kind of circumstances, static absorbing component 2 casing 21 top is equipped with the shower nozzle, in this embodiment, the shower nozzle is connected with arbitrary pure water source, the shower nozzle sets up in two electrode pipes top simultaneously, spray water to the electrode pipe wall of below on, spray water is along electrode pipe downwardly flowing down along with the attached acid mist on the pipe wall, avoided the long-term influence to the electrode pipe on the electrode pipe of acid mist adhesion.
In the process of absorbing the structure, although the spray head is used for cleaning the electrode tube, the short-time adhesion of the acid mist to the tube wall still can lead to the corrosion of the electrode tube, and in order to further reduce the occurrence of the situations, the positive electrode tube 23 and the negative electrode tube 24 are both composed of carbon fibers, so that compared with a metal material electrode, the acid mist is more difficult to corrode the carbon fibers, and the influence of the acid mist on the electrode tube is further reduced.
In the absorption process of the electrostatic absorption assembly 2, when the voltage of the electrostatic field is too large, oxygen in the tail gas generates ozone with the probability of being directly discharged under the action of a high-voltage electric field, pollution can be caused to the air, when the voltage is too small, enough electrons cannot be generated to ionize acid mist, absorption efficiency is insufficient, in order to ensure absorption efficiency and avoid generating new pollutants, an acid mist detector 25 is arranged at an air outlet end of the electrostatic absorption assembly 2, the acid mist detector 25 is electrically connected with a control module 22, the acid mist detector 25 is used for detecting acid mist at an output end and uploading acid mist concentration data to the control module 22, in the embodiment, after the control module 22 receives the acid mist concentration data, the control module is compared with the concentration threshold, the control module 22 indicates that the current adsorption capacity to acid mist particles is insufficient when the comparison result shows that the acid mist concentration is higher than the concentration upper concentration threshold, the control module 22 instructs a transformer to enable the voltage output by the transformer to be higher, a stronger electrostatic field is manufactured, when the comparison result shows that the concentration is lower than the concentration of the acid mist, the comparison result indicates that the required concentration is lower than the concentration, the control module is required to be manufactured, the ozone concentration is prevented from being changed by the control module, and the ozone concentration is required to be changed according to the comparison result, and the concentration of the comparison result is guaranteed.
After the acid liquor flows downwards along the pipe wall and leaves the electrode pipe, the liquid containing acid mist is deposited at the position near the electrode pipe at the bottom of the shell 21, and flows to other positions with probability, for carrying out centralized treatment on the flowing acid mist liquid, the sedimentation tank 26 is arranged at the bottom of the shell 21 around the positive electrode pipe 23 and the negative electrode pipe 24, in the embodiment, the sedimentation tank 26 is annular, the inner wall of the sedimentation tank is tightly attached to the electrode pipe, when the acid mist liquid flows downwards and leaves the electrode pipe, the acid mist liquid directly flows into the inner ring surface of the annular sedimentation tank 26 and is deposited at the bottom of the sedimentation tank 26, and the centralized treatment on the flowing acid mist liquid is completed.
Preferably, the inner wall of the settling tank 26 is subjected to passivation treatment, in this embodiment, the inner wall of the settling tank 26 is coated with an inert material layer, and when the acid mist-containing liquid is deposited in the settling tank 26, the inert material prevents the erosion of the housing 21 by the acid mist
In order to further improve the absorption effect of the absorption device on acid mist, simultaneously, because the two electrode pipes have probability that all charged acid mist cannot be absorbed to the electrode pipes through electrostatic field particles, the charged acid mist has probability that acid liquor with stronger acidity is generated after being combined with water in the spray tower 4, the probability of corrosiveness caused to the spray tower 4 is higher, the absorption component 3 is arranged between the electrostatic absorption component 2 and the spray tower 4, the absorption component 3 is an active carbon absorption layer, after the waste gas passes through the electrostatic absorption component 2, the acid mist which is not absorbed and the charged particles are absorbed by active carbon, the absorption of the acid mist can be enhanced, the charged acid mist particles are prevented from entering the absorption tower, and the absorption effect is enhanced.
