Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to an environmental protection dust removal and desulfurization device. Background Art

[0002] In recent years, the problem of air pollution has become increasingly serious. In modern industrial production, a lot of waste gas discharged from factories contains substances that pollute the environment. The long-term discharge of these harmful substances into the atmosphere not only pollutes the atmospheric environment but also causes great harm to the human body. Most of the waste gas discharged from industries contains sulfur-containing substances and a large amount of soot, and people usually use dust removal and desulfurization devices to treat them.

[0003] Now, generally, a spray tower is used to spray the flue gas to carry out dust removal and desulfurization operations. The sprayed liquid needs to be atomized inside the spray tower and contact the flue gas to produce an oxidation reaction to achieve the effect of dust removal and desulfurization. However, the contact time between the atomized sprayed liquid and the flue gas is short, resulting in insufficient chemical reactions and poor desulfurization effects. Therefore, an environmental protection dust removal and desulfurization device is needed to solve the above problems. Summary of the Utility Model

On one side of the treatment tank 1, a water through-flow groove 8 is opened, and the water through-flow groove 8 is communicated with the water tank 6, so that the desulfurization treatment liquid inside the treatment tank 1 can enter the inside of the water tank 6. On the top side of the water tank 6, a water adding pipe is fixedly connected. The water tank 6 is connected to a water pump 9 through a pipeline. At the outlet of the water pump 9, a water delivery pipe 10 is fixedly connected. At the end of the water delivery pipe 10 far from the water pump 9, a three-way pipe 11 is fixedly connected. At the other two connection ports of the three-way pipe 11, branch pipes 12 are fixedly connected. On the outer surfaces of the two branch pipes 12, several shunt pipes 13 are fixedly connected.

When treating the flue gas, the flue gas is made to rush into the air inlet pipe 4 and is added into the treatment tank 1. Through the filter screen 5, the dust particles in the flue gas can be filtered. The filtered flue gas circulates between the first flow guide plate structure 2 and the second flow guide plate structure 3. And during this process, the water pump 9 is started. The desulfurization treatment liquid located inside the water tank 6 is transported to the inside of the two branch pipes 12 through the water delivery pipe 10 and the three-way pipe 11.

And when the flue gas circulates between the first flow guide plate structure 2 and the second flow guide plate structure 3, the odor in the soot can be adsorbed through the activated carbon adsorption plates 18.

[0025] As an alternative technical solution of the present utility model, the filtering structure 7 includes a slot 701, a filter screen 702 and a sealing pressing plate 703. A plurality of slots 701 are formed in the top side of the water tank 6. The inner walls of the plurality of slots 701 are all inserted with a filter screen 702. The top ends of the plurality of filter screens 702 are all fixedly connected with a sealing pressing plate 703. The size of the sealing pressing plate 703 is larger than that of the slot 701. The diameters of the plurality of filter screens 702 are not the same as the box body, so as to be able to filter the impurities in the desulfurization treatment liquid. And when it is necessary to clean the filter screen 702, the sealing pressing plate 703 drives the filter screen 702 to move out from the inside of the slot 701, so as to be able to clean the filter screen 702.

Under the action of the flow guiding plate 20, the flue gas can be discharged more quickly through the exhaust pipe 15.

[0027] As an alternative technical solution of the present utility model, both the first flow guiding plate structure 2 and the second flow guiding plate structure 3 are inclined, and the plurality of first flow guiding plate structures 2 and the plurality of second flow guiding plate structures 3 are distributed at intervals.

[0028] As an alternative technical solution of the present utility model, the filter screen 5 is located above the air inlet pipe 4 and below the first flow guiding plate structure 2 and the second flow guiding plate structure 3, so that the flue gas can be filtered through the filter screen 5 and then contact with the first flow guiding plate structure 2 and the second flow guiding plate structure 3.

[0029] As an alternative technical solution of the present utility model, the flow dividing pipe 13 is located inside the treatment box 1. The flow dividing pipe 13 is inclined. The number of the flow dividing pipes 13 corresponds to the number of the flow guiding plates 17. The flow dividing pipe 13 is located below the flow guiding plate 17.

Through the connection card block 16 and the connection card slot 19, the flow guiding plate 17 can be stably connected with the treatment box 1.

[0031] An environmental protection dust removal and desulfurization device has the following working principle:

[0032] When treating flue gas, the flue gas is made to rush into the inside of the air pipe 4 and added to the inside of the treatment tank 1. The dust particles in the flue gas can be filtered through the filter screen 5. The filtered flue gas circulates between the first deflector structure 2 and the second deflector structure 3. And in this process, the water pump 9 is started. The desulfurization treatment liquid located inside the water tank 6 is transported to the inside of the two branch pipes 12 through the water delivery pipe 10 and the tee pipe 11. The desulfurization treatment liquid entering the inside of the branch pipe 12 will enter the inside of the shunt pipe 13, and then the atomized desulfurization treatment liquid is sprayed out through the spray head 14, so that the atomized desulfurization treatment liquid is fully contacted with the flue gas, thereby performing the desulfurization treatment operation on the flue gas. The flue gas after dust removal and desulfurization is quickly discharged from the exhaust pipe 15 under the action of the diversion plate 20.

[0033] In summary, for this environmental protection dust removal and desulfurization device, through the combined setting of the first deflector structure 2, the second deflector structure 3, the air inlet pipe 4, the filter screen 5, the water tank 6, the filtering structure 7, the water trough 8, the water pump 9, the water delivery pipe 10, the tee pipe 11, the branch pipe 12, the shunt pipe 13 and the spray head 14, the flue gas can circulate between the first deflector structure 2 and the second deflector structure 3, increasing the residence time of the flue gas inside the treatment tank 1, and in this process, the flue gas is treated, so that the contact time between the flue gas and the spray liquid is longer, thus making the desulfurization treatment effect on the flue gas relatively good. Through the connection blocks 16 and the connection slots 19, the operation of installing and disassembling the deflector 17 is relatively simple, so that it is convenient to replace the activated carbon adsorption plate 18 when it is damaged. Through the filtering structure 7, the liquid after absorbing impurities can be filtered, and through the combined setting of the slot 701, the operation of installing and disassembling the filter net 702 is relatively simple, so that it is convenient to clean the filter net 702.
