Detailed Description
The utility model provides a copper matte granulation steam collection device, includes dust removal section of thick bamboo 10, and dust removal section of thick bamboo 10 top middle part is gas vent 11, and the below middle part is sewage discharge port 12, sets up the air inlet 13 that the direction of admitting air is unanimous with dust removal section of thick bamboo 10 tangential direction on the section of thick bamboo wall of dust removal section of thick bamboo 10, and dust removal section of thick bamboo 10 is inside to be provided with the spray thrower 20 that sprays the washing water to its inner wall.
In the above scheme, the dust-containing steam is guided into the dust removing cylinder from the air inlet 13, a rotational flow along the cylinder wall can be formed after the dust-containing steam enters the dust removing cylinder 10, washing water can form a layer of water film on the cylinder wall, the upward spiral dust-containing steam along the cylinder wall can be fully contacted with the water film so as to collect dust particles conveniently, meanwhile, the dust-containing steam is upward spiral, fine water drops are not easily driven in the air flow direction to be discharged from the air outlet 11, sewage after collecting the dust particles is discharged from the sewage discharge port 12, and purified air is discharged to the atmosphere from the air outlet.
A lower circular partition plate 30 which is horizontally arranged is arranged above the air inlet 13 in the dust removing cylinder 10, guide vanes 31 with the surfaces forming acute angles with the horizontal plane are arranged between the periphery of the lower circular partition plate 30 and the cylinder wall of the dust removing cylinder 10, the guide vanes 31 form an annular array by taking the shaft core of the dust removing cylinder 10 as a reference, the surfaces of the adjacent guide vanes 31 are close to each other and are arranged at intervals, and a cyclone dust removing area 14 is formed in an area between the lower circular partition plate 30 and the sewage outlet 12.
Therefore, the dusty steam can only enter the upper layer from the gap between the guide vanes 31, the washing water can also form a layer of water film on the surface of the guide vanes 31 within a second, the contact area with the dusty steam is reached, meanwhile, the guide direction of the guide vanes 31 can enable the dusty steam to further rotate and rise, and the guide vanes 31 directly connect and fix the lower circular partition plate 30 in the dust removing cylinder 10 without arranging other supports.
A flow deflector 41 with an acute angle formed between the surface and the horizontal plane is arranged between the upper end of the sprayer 20 inside the dust removing cylinder 10 and the horizontally arranged upper annular partition plate 40, the flow deflector 41 forms an annular array by taking the axial core of the dust removing cylinder 10 as a reference, the surfaces of the adjacent flow deflectors 41 are close to and arranged at intervals, the periphery of the upper annular partition plate 40 is connected with the inner wall of the dust removing cylinder 10, and the area between the upper annular partition plate 40 and the exhaust port 11 forms a cyclone dehumidification area 16.
The guide vane 41 guides the exhaust gas to be discharged into a cyclone, and the cyclone dehumidifying zone does not spray the washing water, so that water drops can reach the inner wall of the dust removing cylinder 10 and flow down along with the inner wall under the action of centrifugal force, thereby achieving the purpose of dehumidification.
The sprayer 20 is in a pipe column shape with the shaft core consistent with that of the dust removing cylinder 10, and spray ports 21 for spraying washing water to the inner wall of the dust removing cylinder 10 are densely distributed on the column surface of the sprayer 20. This is more advantageous for the shower 20 to spray the washing water to the inner wall of the dust removing cylinder 10.
The lower circular partition plate 30 is connected with the lower end of the sprayer 20, and the area between the upper annular partition plate 40 and the lower circular partition plate 30 forms a washing and dedusting area 15. This allows the sprinkler 20 to be directly fixed to the lower circular partition 30 without providing an additional bracket.
An inner cylinder 50 is arranged below the periphery of the guide vane 41, and the height of the inner cylinder 50 is 1/2-1/3 of the height of the sprayer 20. Therefore, the dust-containing steam in the upward swirling flow direction can reach the flow deflector 41 from the lower part of the inner cylinder 50, and the washing water can form a water film on the inner wall of the inner cylinder 50, so that the dust removal efficiency is further improved.
The guide vanes 31 and the guide vanes 41 have the same guide direction, and the guide direction of the guide vanes coincides with the initial airflow direction. This is favorable to smooth air flow, and if the flow guide vanes 31 and the flow guide vanes 41 are made to have the same flow guide direction to increase the time for the air flow to stay in the dust removing cylinder 10.
The upper part of the dust removing cylinder 10 is a conical cylinder with a small upper part and a big lower part, the small diameter end of the conical cylinder is provided with an exhaust port 11, the lower part of the dust removing cylinder 10 is a conical cylinder with a small lower part and a big upper part, and the small diameter end of the conical cylinder is provided with a sewage discharge port 12. This facilitates venting and drainage.
The upper end of the sprayer 20 is provided with a water inlet pipe 22, and the water inlet pipe 22 passes through the wall of the dust removing cylinder 10 and is connected with a water source. The upper end of the shower 20 is relatively dry and does not corrode the inlet pipe 22, so the inlet pipe 22 is disposed at this position.
