[0024] Figure 4 It is a top view of the barrier pipeline according to an embodiment of the present invention.

[0025] Please refer to Figures 1-4 , the defoaming and dedusting treatment device according to an embodiment of the present invention includes a barrier pipeline 1 and a liquid atomizer. A plurality of barrier sheets 2 are arranged axially in the barrier pipeline 1. The barrier sheets 2 divide the internal space of the barrier pipeline 1 into multiple barrier chambers 11; the barrier sheets 2 are in a conical funnel shape and have a central hole 21 formed in the center. A plurality of diversion openings 22 are arranged radially on the barrier sheets 2; the liquid atomizer includes an atomization pipeline 3 and an atomization unit. The atomization pipeline 3 is coaxially and vertically inserted into the barrier pipeline 1 and is located in the central hole 21 of the barrier sheet 2. A set of atomization units is arranged below each barrier sheet 2, so that the barrier sheets 2 and the atomization units are arranged at intervals; the atomization units are connected to the atomization pipeline 3. The barrier sheets 2 and the atomizer unit divide the space in the barrier pipeline 1 into a maze shape, which is conducive to the full contact between the atomized liquid and the foam and dust in the barrier chamber 11.

[0026] Specifically, an atomizer mounting flange 5 is provided at the top of the barrier pipeline 1, and the atomization pipeline 3 is fixedly installed through the atomizer mounting flange 5; the top of the atomization pipeline 3 is bent at 90 degrees and passes through the outer wall of the atomizer mounting flange 5.

[0027] Please continue to refer to Figure 1 and Figure 2 , for the defoaming and dedusting treatment device according to an embodiment of the present invention, the outer diameter of the atomization pipeline 3 is smaller than the diameter of the central hole 21, so that a sedimentation gap is formed between the central hole 21 and the atomization pipeline 3. The slurry formed after the atomized liquid is mixed with the foam and dust in the barrier chamber 11 can settle downward along the barrier sheet 2 and flow back through the sedimentation gap. The axial spacing of the plurality of barrier sheets 2 decreases sequentially from the inlet side to the outlet side, and the diameters of the central holes of the plurality of barrier sheets 2 decrease sequentially from the inlet side to the outlet side, so that the sedimentation gaps of the multiple barrier chambers decrease sequentially, in order to form a certain air pressure difference and achieve a better defoaming and dedusting effect. In addition, micro-hook-shaped protrusions can be formed on the inner surface of the barrier sheet 2, and adjacent micro-hook-shaped protrusions are hooked to form a net structure, which can prevent the dust from being wrapped into a group and deposited on the barrier sheet.

[0028] Specifically, each group of atomization units includes a plurality of atomization heads 4 , and the plurality of atomization heads 4 are arranged at equal intervals along the circumference of the atomization pipeline 3 , and the atomization heads 4 are connected to the atomization pipeline 3 .

[0029] Preferably, the atomizing head 4 is tilted upward. In a specific embodiment, the angle between the barrier sheet 2 and the outer wall of the barrier pipe 1 is 45-60 degrees, the angle between the atomizing head 4 and the atomizing pipe 3 is 45-60 degrees, and the atomizing head 4 is arranged parallel to the barrier sheet 2 and located in the middle of the adjacent barrier sheets 2, which can ensure that the atomized liquid sprayed by the atomizing head 4 is in full contact with the foam and dust in the barrier cavity 11, and can cooperate with the conical funnel-shaped barrier sheet to make the dust and foam settle quickly.

[0030] Preferably, the guide port 22 is staggered with the atomizing head 4 so that the atomized liquid sprayed from the atomizing head 4 stays in the barrier cavity 11 and fully contacts with the foam and dust, thereby preventing the atomized liquid from directly flowing out of the guide port 22 .

[0031] Please continue to see Figure 3 and Figure 4 In the defoaming and dust removal device of the embodiment of the present invention, the plurality of guide ports 22 are evenly distributed on the barrier sheet 2 , and the guide ports 22 are connected to the central hole 21 .

[0032] Please also see Figure 5 In the defoaming and dust removal treatment device of the embodiment of the present invention, a plurality of atomizing nozzles are evenly distributed on the end and outer wall of the atomizing head 4. The plurality of atomizing nozzles are irregular shaped holes, which can form local transverse flow, so that the foam dust can be better mixed and flowed out.

[0033] In the actual use of the defoaming and dust removal device of the embodiment of the present invention, foam and dust enter the barrier chamber 11 from the bottom of the barrier pipe 1 through the guide port 22 and the sedimentation gap, and are broken up and mixed by the atomized liquid sprayed from the atomizing head 4. The slurry formed after mixing settles downward along the funnel-shaped barrier piece 2 and refluxes through the sedimentation gap, and the purified gas is discharged from the guide port 22 to the top of the barrier pipe 1.

[0034] To sum up, in the defoaming and dust removal device of the embodiment of the present invention, a barrier sheet 2 is arranged in the barrier pipe 1 to divide the internal space of the pipe into a plurality of barrier chambers 11, and the atomizing head 4 is connected to the atomizing pipe 3 and is arranged in the barrier chamber 11. The atomizing nozzle of the atomizing head 4 sprays atomized liquid to break up and mix the foam and dust entering from the bottom of the barrier pipe 1 in the barrier chamber 11, and the mixed slurry settles downward along the barrier sheet 2 and refluxes through the sedimentation gap, and the purified gas is discharged upward from the guide port 22, so as to effectively remove foam and dust; reduce the influence of foam and dust on subsequent processes; reduce the risk of pipe blockage and improve production efficiency; simple structure, easy maintenance and low use cost.

[0035] Although the present invention has been disclosed above in its preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to that defined by the claims.
