DETAILED DESCRIPTION
[0023] The present application is further described below in conjunction with the accompanying drawings and embodiments. Example 1
[0024] A high-efficiency exhaust gas purification device, such as Figure 1-Figure 4 As shown, it includes: a purification box 1, an air inlet 2 is provided on one side of the purification box 1, an air outlet 3 is provided on the side of the purification box 1 away from the air inlet 2, two layers of water spray pipes 5 are provided in the purification box 1, and a plurality of nozzles 6 are evenly distributed on the two layers of water spray pipes 5. Clear liquid is sprayed from the nozzles 6 to form a water mist covering the cross-section of the purification box 1, and the water mist adsorbs the dust in the exhaust gas to form a turbid liquid, thereby solving the dust problem in the exhaust gas. A drain port 19 is provided at the bottom of the purification box 1, and a baffle 7 is also provided on the purification box 1. The baffle 7 is fixedly connected to the top of the purification box 1, and a filter layer 8 is also provided between the baffle 7 and the air outlet 3. The baffle 7 can prevent the water vapor of the nozzle 6 from being directly sprayed into the filter layer 8 to affect the filtration of the gas. The filter layer 8 will filter the exhaust gas adsorbed by the clear liquid again to improve the filtration efficiency of the purification box 1.
[0025] like Figure 1 As shown, the air inlet 2 and the air outlet 3 are axially symmetrical with respect to the center line of the purification box 1 , and an exhaust fan 4 is provided on the air outlet 3 , through which the purified gas is sucked out.
[0026] like Figure 1-2 As shown, the two layers of water spray pipes 5 are divided into an upper layer of water spray pipes 12 and a lower layer of water spray pipes 13 , wherein the upper layer of water spray pipes 12 are located at the top of the purification box 1 , and the lower layer of water spray pipes 13 are located in the middle of the purification box 1 .
[0027] like Figure 2 As shown, it also includes a water pump and a water storage tank 11. Both ends of the water spray pipe 5 are fixedly connected to the purification box 1. One end of the water spray pipe 5 passes through the purification box 1 and is connected to the water pump through a water pipe. The water pump is located in the water storage tank 11. The clear liquid in the water storage tank 11 is transported to the water spray pipe 5 by the water pump and sprayed out from the nozzles 6 of the two layers of water spray pipes 5. The clear liquid sprayed from the nozzles 6 on the two layers of water spray pipes 5 forms a water curtain to adsorb dust in the exhaust gas.
[0028] like Figure 1As shown, it also includes a sedimentation box 10, and the drain port 19 is connected to the sedimentation box 10 through a pipeline. After the turbid liquid that absorbs dust is precipitated through the sedimentation box 10, the upper layer is clear liquid that can be recycled, and the lower layer is dirt. The clear liquid in the upper layer is first extracted and recycled, and then the dirt in the lower layer of the sedimentation box 10 can be discharged.
[0029] like Figure 1 As shown, the baffle 7 is located far above the drain outlet 19, and a gas circulation space is left between the baffle 7 and the bottom of the purification box 1. The baffle 7 can block the water vapor above from being directly discharged from the air outlet 3, and can also allow the water vapor attached to the baffle 7 to fall directly into the drain outlet 19, so as to flow into the sedimentation box 10 for sedimentation.
[0030] like Figure 1 As shown, the filter layer 8 and the baffle 7 are parallel to each other. Figure 3 As shown, the filter layer 8 includes a first mesh plate 15 and a second mesh plate 16, the first mesh plate 15 and the second mesh plate 16 are fixedly connected to the side of the purification box 1, and an activated carbon layer 17 and a calcium oxide layer 18 are provided between the first mesh plate 15 and the second mesh plate 16. The activated carbon layer 17 is located on the side of the filter layer 8 close to the baffle 7, and the calcium oxide layer 18 is located on the side of the filter layer 8 close to the air outlet 3. The activated carbon layer 17 adsorbs harmful substances, and the calcium oxide layer 18 adsorbs excess water vapor.
[0031] like Figure 1 As shown, the bottom of the purification box 1 is also provided with a drainage plate 9, and an angle of 30 degrees is set between the drainage plate 9 and the bottom plate of the purification box 1, and the drainage plate 9 is inclined toward the drain port 19, as shown in FIG. Figure 4 As shown, the drainage plate 9 is provided with a water flow groove 14 , the cross section of which is triangular, and the clear liquid sprayed from the nozzle 6 flows into the drain port 19 by utilizing the inclination angle between the drainage plate 9 and the bottom of the purification box 1 .
[0032] The side of the purification box 1 is also provided with an inspection port, through which the activated carbon layer 17 and the calcium oxide layer 18 in the filter layer 8 can be replaced.
[0033] In the technical solution of the present application, by improving the layout of the water spray pipe 5 and the position of the nozzle 6, the process of using the gear system to drive the nozzle 6 to rotate is omitted. By using the upper and lower layers of water spray pipes 5 and multiple nozzles 6 evenly distributed on the water spray pipes 5, a water mist surface perpendicular to the bottom of the purification box 1 can be formed in the purification box 1. In this way, when the exhaust gas passes through this layer of water mist surface, it can contact the water mist formed by the clear liquid, and the dust in the exhaust gas is adsorbed in the clear liquid mist to form a turbid liquid. The turbid liquid is blocked by the baffle 7 and finally falls on the drainage plate 9, and flows into the sedimentation box 10 through the drain port 19. After sedimentation, the upper clear liquid can enter the water storage tank 11 for recycling again. The exhaust gas adsorbed by the clear liquid enters the filter layer 8 from under the baffle 7 for filtration. The activated carbon layer 17 in the filter layer 8 can adsorb harmful substances in the exhaust gas, and the calcium oxide layer 18 can absorb excess water vapor. Finally, the filtered exhaust gas is discharged from the outlet 3.
[0034] Although the above describes the specific implementation methods of the present application in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present application. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present application, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present application.
