The function of the inner cavity is that a plurality of spraying mechanisms 6 are fixedly connected to the lower annular array of the diversion mechanism 5, which can realize the function of spraying the reaction liquid in the form of mist to desulfurize and denitrify the exhaust gas; a gas transmission mechanism 7 is fixedly connected to the middle part of the inner cavity of the dust removal box 1, which can realize the function of dispersing and discharging the exhaust gas into the inner cavity of the dust removal box 1; a filtering mechanism 8 is fixedly connected to the lower part of the inner cavity of the dust removal box 1, which can realize the function of filtering the dust contained in the exhaust gas that falls with the reaction liquid after spraying; a recovery mechanism 9 is fixedly connected to the bottom wall of the inner cavity of the dust removal box 1, which can realize the function of collecting the reaction liquid scattered after spraying.

[0023] In order to achieve the purpose of transporting the reaction liquid required by the shunt tube 52, refer to Figure 2 The liquid supply mechanism 4 includes a liquid storage barrel 41, and a water pump 42 is fixedly connected to the middle of the bottom wall of the inner cavity of the liquid storage barrel 41, which can realize the function of transporting the reaction liquid to the inner cavity of the diversion tube 52 through the connecting pipe 53. The upper right side of the outer surface of the liquid storage barrel 41 is fixedly connected to a liquid injection pipe 43.

[0024] In order to achieve the purpose of transporting the reaction liquid to the inner cavities of the plurality of branch pipes 61, see Figure 2The diversion mechanism 5 includes a mounting shell 51, and a diversion tube 52 is fixedly connected to the inner cavity of the mounting shell 51, which can realize the function of transporting the reaction liquid to the inner cavity of the diversion branch tube 61 connected thereto. A connecting tube 53 is fixedly connected to the middle part of the upper side of the outer surface of the diversion tube 52, and the upper end of the outer surface of the connecting tube 53 is fixedly connected to the lower output end of the water pump 42.

[0025] In order to achieve the purpose of desulfurization and denitrification of exhaust gas by spraying the reaction liquid in the form of mist, refer to Figure 2 The spray mechanism 6 includes a branch pipe 61, and a plurality of spray heads 62 are fixedly connected to the outer surface of the branch pipe 61 at intervals on one side close to the middle of the inner cavity of the dust removal box 1.

[0026] When it is necessary to desulfurize and denitrify the exhaust gas discharged from the intake pipe 31, the reaction liquid diverted through the diversion pipe 52 will be transported to the inner cavity of a plurality of diversion branches 61, and then sprayed into the inner cavity of the dust removal box 1 in the form of water mist through a plurality of spray heads 62. At this time, the exhaust gas floating up from the lower part of the inner cavity of the dust removal box 1 will fully contact with it and carry out desulfurization and denitrification work.

[0027] In order to achieve the purpose of dispersing the exhaust gas into the inner cavity of the dust removal box 1, refer to Figure 3 The gas delivery mechanism 7 includes a gas delivery square tube 71, and a plurality of gas delivery nozzles 72 are symmetrically fixedly connected to the front and rear ends of the outer surface of the gas delivery square tube 71, which can expand and disperse the exhaust gas input through the air inlet pipe 31 into the inner cavity of the dust removal box 1. The upper end of the outer surface of the gas delivery square tube 71 is fixedly connected with an arc plate 73, which can enable the scattered reaction liquid to slide down along the upper surface of the arc plate 73 to avoid its accumulation on the upper end of the outer surface of the gas delivery square tube 71.

[0030] After being filtered by the filter rack 82 , the reaction liquid will drip into the inner cavity of the liquid collecting box 91 for collection, and will be accumulated in the right part of the inner cavity of the liquid collecting box 91 through the slope of the inclined block 92 , and can finally be discharged to the outside through the drain pipe 93 for secondary utilization.

[0031] It should be noted that the specific installation method, circuit connection method and control method of the water pump 42 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0032] The working principle of the utility model is as follows: first, the reaction liquid is injected into the inner cavity of the liquid storage barrel 41 through the injection pipe 43, and then, driven by the water pump 42, the reaction liquid enters the inner cavity of the shunt pipe 52 through the connecting pipe 53, and then enters the inner cavity of several shunt branch pipes 61 through the transportation of the shunt pipe 52, and finally sprayed out in the form of water mist through several spray heads 62.

At this time, the exhaust gas will float up to fully contact and react with the reaction liquid mist until it rises to the top of the inner cavity of the dust removal box 1 and is finally discharged to the outside through the exhaust pipe 3. The scattered reaction liquid mist will fall downward to the upper surface of the filter rack 82. The dust and other impurities contained in the reaction liquid condensed into water droplets can be filtered through the filter rack 82, and finally drip into the inner cavity of the liquid collecting box 91, and will be accumulated in the right part of the inner cavity of the liquid collecting box 91 through the slope of the inclined block 92, and finally discharged to the outside through the drain pipe 93 for secondary utilization.
