[0024] See also Figures 1 to 3 Now, the smoke treatment equipment for asphalt concrete provided by the utility model is described. The smoke treatment equipment for asphalt concrete comprises a water tank 10, a shearing assembly 20, a guide tube 30 and an absorption tower 40. The water tank 10 is provided with an air outlet pipe 11 and an inlet pipe 12 at the top, a drainage pipe 13 and an air inlet pipe 14 for communicating with a mixing tank at the bottom, and the air inlet pipe 14 is used to guide the smoke in the mixing tank to the water tank 10; the shearing assembly 20 extends downward from the top of the water tank 10 into the water tank 10, and the outer periphery of the shearing assembly 20 is provided with a disturbance blade 23 extending outward and upward and used for shearing bubbles; the guide tube 30 is arranged on the inner wall of the water tank 10 and is sleeved on the outer periphery of the disturbance blade 23, the guide tube 30 is located above the outlet end of the inlet pipe 14, and the guide tube 30 is used to guide the water above the guide tube 30 to the bottom of the guide tube 30; the absorption tower 40 is arranged on one side of the water tank 10 and is communicated with the air outlet pipe 11 for purifying the smoke, and the top of the absorption tower 40 is provided with an exhaust pipe 41.

[0025] Furthermore, valves are provided on the air outlet pipe 11, the water inlet pipe 12, the drain pipe 13 and the air inlet pipe 14 to facilitate the opening and closing of the pipelines.

[0026] The embodiment of the present application provides a flue gas treatment device for asphalt concrete. During its actual use, water is pre-added into the water tank 10 through the water inlet pipe 12 so that it covers the guide tube 30. The flue gas in the mixing tank enters the water tank 10 through the air inlet pipe 14. The flue gas enters the water tank 10 to generate bubbles. The shear component 20 drives the disturbance blades 23 to shear the bubbles and stir the water, so that the bubbles become smaller and fully contact with the water, so that harmful substances dissolved in water in the flue gas remain in the water. The disturbance of the disturbance blades 23 causes the water in the guide tube 30 to form a vortex, thereby sucking the water above the guide tube 30 into the guide tube 30, and then going out from the bottom of the guide tube 30 after being disturbed by the disturbance blades 23, forming living water, which continuously impacts the bubbles to break them into small bubbles. This cycle allows the water to fully absorb the harmful substances dissolved in water in the flue gas, and finally the flue gas enters the absorption tower 40 through the outlet pipe 11 for further purification, and is discharged from the exhaust pipe 41, which can effectively purify the flue gas, avoid direct emission of the flue gas to pollute the environment, and ensure the health of the staff.

[0027] Compared with the prior art, the flue gas treatment equipment for asphalt concrete provided in this embodiment drives the disturbance blades 23 to shear the flue gas bubbles and stir the water through the shearing assembly 20, so that the bubbles become smaller and fully contact with the water, so that the harmful substances dissolved in water in the flue gas remain in the water. Under the disturbance of the disturbance blades 23, the water in the guide tube 30 forms a vortex, so that the water above the guide tube 30 is sucked into the guide tube 30, and then after the disturbance of the disturbance blades 23, it goes out from the bottom of the guide tube 30 to form live water, which continuously impacts the bubbles and breaks them into small bubbles. In this cycle, the water fully absorbs the harmful substances dissolved in water in the flue gas, and finally the flue gas enters the absorption tower 40 through the outlet pipe 11 for further purification, and is discharged from the exhaust pipe 41, which can effectively purify the flue gas, avoid direct emission of flue gas to pollute the environment, and ensure the health of the staff.

[0028] In a possible implementation, the shearing assembly 20 is configured as follows: Figure 1 The structure shown, see Figure 1 The shearing assembly 20 includes a driving member 21 and a rotating shaft 22. The driving member 21 is arranged on the top wall of the water storage tank 10, and the driving end of the driving member 21 extends into the water storage tank 10; the rotating shaft 22 is connected to the extended end of the driving member 21 and extends downward to protrude from the lower edge of the guide cylinder 30, and the disturbance blade 23 is connected to the outer periphery of the rotating shaft 22.

[0029] Specifically, the flue gas enters the water storage tank 10 through the air inlet pipe 14 and generates bubbles. The driving member 21 drives the disturbance blades 23 through the rotating shaft 22 to not only disturb the water, but also form a vortex in the water in the guide tube 30 under the disturbance of the disturbance blades 23, thereby sucking the water above the guide tube 30 into the guide tube 30, and then going out from the bottom of the guide tube 30 after being disturbed by the disturbance blades 23 to form living water, which continuously impacts the bubbles and breaks them into small bubbles. Combined with the further shearing of the flue gas bubbles by the disturbance blades 23, the harmful substances dissolved in water in the flue gas can be fully dissolved in the water.

[0030] In some embodiments, see Figure 1 The lower end of the rotating shaft 22 is provided with a shearing blade 50 located above the outlet end of the air inlet pipe 14.

[0031] Specifically, the shear blade 50 is used to shear the smoke bubbles generated at the outlet end of the air inlet pipe 14, so that the bubbles become small bubbles and fully contact with water, so that the harmful substances soluble in water in the smoke can be fully dissolved in the water.

[0032] In some embodiments, see Figure 1 A plurality of disturbance blades 23 are arranged around the outer circumference of the rotating shaft 22 , and two groups of disturbance blades 23 are arranged at intervals along the axial direction of the rotating shaft 22 .

[0033] Specifically, the provision of the two groups of disturbance blades 23 enhances the effect of forming a vortex and also enhances the shearing effect on the bubbles entering the guide tube 30 .

The annular pipe 60 is located below the guide tube 30 , and an air diffusion hole 61 is provided at the top of the annular pipe 60 .

[0035] Specifically, a plurality of diffusion holes 61 are provided in the circumferential direction of the annular tube 60. The provision of the annular tube 60 increases the diffusion effect of smoke in water and strengthens the full absorption of harmful substances dissolved in water in the smoke.

[0036] In a possible implementation, the absorption tower 40 is as follows: Figure 1 The structure shown, see Figure 1 The absorption tower 40 includes an absorption tank 42, an absorption member 43 and a cover 44. The absorption tank 42 has an upward opening. The absorption tank 42 is arranged on one side of the water storage tank 10 and is arranged higher than the water storage tank 10. The bottom of the absorption tank 42 is connected to the exhaust pipe 11; the absorption member 43 is arranged in the absorption tank 42 for purifying the flue gas; the cover 44 is arranged on the top of the absorption tank 42 and is used to block the opening. The exhaust pipe 41 is arranged on the top of the cover 44.

[0037] Specifically, the flue gas enters the absorption tank 42 after being preliminarily purified in the water storage tank 10, and is discharged into the air through the exhaust pipe 41 after being further purified in the absorption element 43, thereby improving the purification effect of the flue gas.

[0038] Furthermore, the cover 44 is detachably connected to the absorption tank 42, which facilitates the removal of the cover 44 for regular replacement of the absorption member 43, thereby improving convenience.

[0039] In some embodiments, see Figure 1 The absorbent 43 includes a desiccant layer 434, an air filter cotton layer 433, a glass fiber filter layer 432 and an activated carbon adsorption layer 431 which are sequentially arranged in the absorption tank 42 from bottom to top.

[0040] Specifically, the desiccant layer 434, the air filter cotton layer 433, the glass fiber filter layer 432 and the activated carbon adsorption layer 431 can further adsorb the moisture and remaining harmful substances in the flue gas, thereby ensuring the purification effect of the flue gas.

[0041] In some embodiments, see Figure 1A flange 70 is provided at the upper end of the absorption tank 42 , and the cover 44 is connected to the flange 70 via a bolt assembly 80 .

[0042] Specifically, when the absorber 43 needs to be replaced, the cover 44 can be opened by removing the bolt assembly 80, thereby improving the convenience of use.

[0043] In some embodiments, see Figures 1 to 3 A plurality of first mounting grooves 441 opening outward are provided on the outer peripheral wall of the cover 44, a plurality of second mounting grooves 71 corresponding to the first mounting grooves 441 are provided on the outer peripheral wall of the flange 70, and the bolt assembly 80 is arranged in the first mounting groove 441 and the second mounting groove 71.

[0044] Specifically, the bolt assembly 80 includes a bolt located in the first mounting groove 441 and the second mounting groove 71 and a nut threadedly connected to the bolt. During installation, the first mounting groove 441 and the second mounting groove 71 on the cover 44 and the flange 70 are first aligned, and then the nut is pre-connected to the lower end of the bolt, and the distance between the nut and the bolt head is kept greater than the total thickness of the cover 44 and the flange 70, and then the bolt is inserted into the first mounting groove 441 and the second mounting groove 71 to reduce the number of turns of the nut during the locking process. In addition, during disassembly, it is only necessary to slightly loosen the bolt and the nut, and move the bolt and the nut as a whole to the opening of the first mounting groove 441 and the second mounting groove 71 (outside the cover 44 and the flange 70), so that the cover 44 and the flange 70 can be disassembled, and the cover 44 and the absorption tank 42 can be quickly disassembled.

[0045] In a possible implementation, the air intake pipe 14 is configured as follows: Figure 1 The structure shown, see Figure 1 The inlet end of the air inlet pipe 14 is bent upward to protrude from the top surface of the water storage tank 10 .

[0046] Specifically, the inlet end of the air inlet pipe 14 is higher than the liquid level in the water storage tank 10 to prevent the water in the water storage tank 10 from being sucked back into the mixing tank.

[0047] Furthermore, a pump body 90 is provided on the air inlet pipe 14 for conveying the smoke in the mixing tank to the water storage tank 10, thereby enhancing the efficiency of conveying the smoke.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
