[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] In the embodiments, by Figure 1-4 An industrial waste gas treatment device is provided. This utility model includes a treatment box 1, an exhaust pipe 2 and an intake pipe 3 inside the treatment box 1, an adapter 4 fixedly connected inside the treatment box 1, a spray plate 5 fixedly connected to the outside of the adapter 4, two supports 6 arranged vertically inside the treatment box 1, each of the two supports 6 having a packing layer 7 inside, a water outlet pipe 8 fixedly connected to the bottom of the treatment box 1, a sedimentation tank 9 fixedly connected to the outside of the water outlet pipe 8, a filter box 10 fixedly connected to the outside of the sedimentation tank 9 via a pipe, a plurality of filter frames 11 inside the filter box 10, a water pump 12 fixedly connected to the filter frames 11 via a pipe, the water pump 12 fixedly connected to the adapter 4 via a pipe, and a water tank 13 fixedly connected to the water pump 12 via a pipe.
[0028] The air inlet pipe 3 is located on the side of the treatment box 1, and the water outlet pipe 8 is located at the bottom of the treatment box 1. Both the air inlet pipe 3 and the air outlet pipe 2 are equipped with fans.
[0029] In this embodiment, during actual use, the fan discharges and extracts exhaust gas inside the exhaust pipe 2 and the intake pipe 3 respectively. The intake pipe 3 on the side will not affect the water outlet pipe 8 below, and will not cause the washing liquid to backflow.
[0030] Among them, a distribution plate 14 is fixedly connected between the two packing layers 7. The distribution plate 14 is concave and has a number of liquid outlet holes inside.
[0031] In this embodiment, during actual use, after the washing liquid enters the upper packing layer 7, the flow path of the washing liquid is restricted or changed. The washing liquid falls onto the distribution plate 14, is collected again, and dispersed downwards, so that it can fully contact and wash the rising exhaust gas under the mixing of the two packing layers 7.
[0032] Each of the multiple filter frames 11 has a baffle 15 fixedly connected to its top by bolts, and the multiple baffles 15 are connected to the filter box 10 by bolt threads.
[0033] In this embodiment, during actual use, the baffle 15 and the filter frame 11, as well as the baffle 15 and the filter box 10, can be disassembled. After the baffle 15 and the filter frame 11 are removed from the filter box 10, the filter frame 11 can be removed by bolts for replacement.
[0034] Each of the baffles 15 has a handle 16 fixedly connected to its top, and each of the baffles 15 has a sealing rubber gasket inside.
[0035] In this embodiment, during actual use, the handle 16 can lift the disassembled baffle 15 for easy removal, and the sealing rubber gasket can enhance the sealing of the connection and prevent leakage of washing liquid.
[0036] The sedimentation tank 9 is internally fixedly connected to a limiting frame 17, the top surface of which is inclined downwards. The sedimentation tank 9 is internally fixedly connected to a number of columns 18.
[0037] In this embodiment, during actual use, the washing liquid for cleaning the exhaust gas will flow into the sedimentation tank 9. The liquid discharge pipe is located in the upper part of the sedimentation tank 9. Some of the impurities in the exhaust gas in the washing liquid will settle and slide down along the inclined limiting frame 17. Multiple columns 18 can block and disperse the water flow to a certain extent, making the water flow more stable in the sedimentation tank, reducing the turbulence and shaking of the water flow, thereby reducing the disturbance of the water flow to the sediment and helping the sediment to settle better.
[0038] Working principle:
[0039] During the waste gas treatment process, the waste gas enters through the inlet pipe 3 and rises under the suction of the fan, passing through the packing layer 7. The packing typically has a large specific surface area. The water pump 12 draws the washing liquid from the water tank 13 and sprays it out through the spray plate 5. The waste gas passes through the packing layer 7, which is filled with washing liquid. The packing layer 7 can be Raschig ring packing, with raised ribs on both its inner and outer surfaces. These ribs increase the surface area of the packing. When the waste gas and absorbent flow in the packing layer, the absorbent forms a liquid film on the surface of the packing, and the waste gas passes through the liquid film. This results in gas-liquid contact and mass transfer near the surface of the packing, increasing the contact area with the waste gas and facilitating the removal of impurities in the waste gas. The absorption and washing process, with two layers of packing 7 enhancing the washing effect of the waste gas, results in the washed waste gas being discharged from the top. To reduce the moisture content in the waste gas, a demister can be installed in the outlet pipe 2 to remove the impact of liquid droplets carried in the washed gas on subsequent equipment. The washing of the waste gas will continue to flow downwards and into the sedimentation tank 9, where some sulfur-containing precipitates will settle at the bottom. The pipeline absorbs the washing liquid from above under the action of the water pump 12 and passes through the filter frame 11. The multiple filter frames 11 contain filter mesh layers, activated carbon layers, iron oxide layers, etc., with corresponding filter layers set according to the actual situation of the wastewater and waste gas. After filtration, the washing liquid can be reused by the water pump 12 through the spray plate 5.
