Description

Technical Field

[0001] The invention relates to the technical field of dust removal equipment, and in particular to a water curtain dust removal equipment. Background Art

[0002] In the existing process, during the production and processing of glass fiber wool, the waste gas generated needs to be dusted. When the airflow containing glass fiber wool enters the cyclone, the airflow forms a rotational motion in the cyclone. Due to the centrifugal force generated by the rotation, the larger glass fiber wool particles are thrown toward the cylinder wall, and slide down the cylinder wall to the bottom collection port under the action of gravity, while the fine particles will be discharged through the exhaust pipe at the top with the airflow. Because the fine particles and the excess fiber wool are lighter and smaller, they are easily adsorbed on the filter screen inside the exhaust pipe, which is not easy to collect, affecting the passage of the airflow, and some fine particles will be discharged with the airflow, polluting the environment.

[0003] Therefore, a water curtain dust removal device is generally installed at the exhaust pipe of the cyclone to collect fine particles and fine fiber cotton.

[0004] The water curtain dust removal equipment and the water curtain dust removal method disclosed in Chinese patent CN108295586A include a circulating air system, a spraying device, a primary dust removal filter device and a secondary dust removal filter device; the circulating air system is connected to the ceiling and wall of the workshop to form a circulating air; the spraying device is connected to the wall of the workshop; the primary dust removal filter device and the secondary dust removal filter device are connected to the water outlet of the water outlet pipe in sequence. The water curtain dust removal method includes wind pressure dust removal, water curtain dust removal, primary dust filtration treatment and secondary dust filtration treatment.

[0005] However, compared with the existing technology and the comparative scheme, it can be seen that the water curtain dust removal equipment still has the following problems in actual use:

[0006] In existing water curtain dust removal equipment, the position of the water curtain is usually fixed, and the water curtain is often formed by the downward flow of water due to gravity, and the dust-laden airflow needs to pass through the water curtain or impact the water curtain, so that the fine particles in the dust-laden airflow adhere to the water curtain and are captured by the water flow for dust removal. When the dust-laden airflow passes through the water curtain or impacts the water curtain, when the dust-laden airflow velocity is fast and the impact force is strong, the integrity and uniformity of the water curtain will be affected. When the dust-laden airflow velocity is slow and the impact force is weak, the particles in the dust-laden airflow cannot evenly contact the water curtain, thereby affecting the treatment effect of the dust-laden airflow.

One end of the first connecting pipe 401 is provided with a second transmission gear 402, and the second transmission gear 402 is meshed with the first transmission gear 3. The second transmission gear 402 is provided with a rotating joint 403, and the end of the rotating joint 403 away from the first connecting pipe 401 is provided with a water inlet pipe 404. The end of the first connecting pipe 401 away from the second transmission gear 402 is provided with a spiral plate 405, the shape of the spiral plate 405 is an inverted cone, and the plate surface of the spiral plate 405 is inclined downward. The second connecting pipe 406 is provided inside the first connecting pipe 401, and the second connecting pipe 406 is provided with a nozzle 407, and the number of the nozzles 407 is multiple;

[0037] like Figure 3 and Fig.10 As shown, the second dust removal component 5 includes a connecting frame 501, a connecting frame 502, a through groove 503 and an auxiliary net 504. The connecting frame 501 is rotatably connected to the inside of the dust removal cylinder 1. A connecting frame 502 is provided in the middle of the connecting frame 501. The connecting frame 501 is fixedly connected to the second connecting pipe 406 through the connecting frame 502. A through groove 503 is opened on the connecting frame 501. An auxiliary net 504 is provided at the bottom of the connecting frame 501. There are multiple auxiliary nets 504, which are distributed in a circular array at the bottom of the connecting frame 501. The number of through grooves 503 is the same as the number of auxiliary nets 504, and the positions of the through grooves 503 correspond to the positions of the auxiliary nets 504. The cross-section of the auxiliary net 504 is "L"-shaped, and a groove structure with a cross-section of "C" is formed between the auxiliary net 504 and the dust removal cylinder 1.

[0038] The working process is as follows:

[0039] S1. When in use, start the driving member 2, the driving member 2 drives the first transmission gear 3 to rotate, the first transmission gear 3 drives the second transmission gear 402 to rotate, the second transmission gear 402 drives the first connecting pipe 401 to rotate, the first connecting pipe 401 drives the spiral plate 405 and the second connecting pipe 406 to rotate, the second connecting pipe 406 drives the nozzle 407 and the connecting frame 502 to rotate, the connecting frame 502 drives the connecting frame 501 to rotate, and the connecting frame 501 drives the auxiliary net 504 to rotate;

[0040] S2, water enters from the water inlet pipe 404, passes through the rotary joint 403 and enters the first connecting pipe 401, and flows along the first connecting pipe 401;

[0041] S3, a part of the water flow is ejected from the gap of the spiral plate 405 to form a conical spiral water curtain, the starting point of the conical spiral water curtain is the gap of the spiral plate 405, and the end point is the annular groove formed by the connecting frame 501 and the dust removal cylinder 1, and the water in the annular groove falls from the through groove 503 onto the auxiliary net 504, forming a vertical water curtain on the auxiliary net 504;

[0042] S4, another part of the water flow enters the second connecting pipe 406, and is sprayed out from the nozzle 407, spraying on the inner wall of the auxiliary net 504 and the dust removal cylinder 1, ensuring the integrity of the water curtain on the inner wall of the auxiliary net 504 and the dust removal cylinder 1. The dust-containing gas enters from the air inlet pipe 102, enters the dust removal cylinder 1 through the spiral tube 101, and flows upward along the inner wall of the dust removal cylinder 1 in a spiral manner;

[0043] S5. During the flow, the dust-laden airflow passes between the auxiliary net 504 and the inner wall of the dust removal cylinder 1. There is a vertical water curtain formed by water flow on the auxiliary net 504. When the dust-laden airflow impacts or passes through the water curtain on the auxiliary net 504, the integrity and uniformity of the water curtain are affected. Under the action of the water flow passing through the through groove 503 above and the water flow sprayed from the nozzle 407, the water curtain on the auxiliary net 504 becomes complete and uniform after the airflow passes.

[0044] S6. Since there are multiple auxiliary nets 504 and the dust-laden airflow is spirally upward, the position of the vertical water curtain on each auxiliary net 504 that is impacted by the dust-laden airflow is different. Since the connecting frame 502 drives the auxiliary net 504 to rotate along with the second connecting pipe 406 through the connecting frame 501, and the rotation direction is opposite to the spiral flow direction of the dust-laden airflow, the position of each auxiliary net 504 that is impacted by the dust-laden airflow is also different each time, ensuring the integrity and uniformity of the vertical water curtain at the position on the auxiliary net 504 that is impacted by the dust-laden airflow each time.

[0045] S7. As the dust-laden airflow rises, when the dust-laden airflow reaches the spiral plate 405, the conical spiral water curtain formed at the gap between the spiral plates 405 again absorbs the fine particles in the dust-laden airflow, and the water retaining net 106 blocks the water droplets splashed by the airflow to prevent the splashed water droplets from flowing to the air outlet pipe 105 along with the airflow, thereby avoiding affecting the subsequent equipment. The airflow after dust removal by the vertical water curtain and the conical spiral water curtain is discharged from the air outlet pipe 105.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
