Description

  The present invention relates to a dust collector, and more particularly, to a wet dust collector that collects dust with mist.

  There exists a thing shown in patent document 1 as a conventional wet dust collector. In the invention of Document 1, absorption water is applied to the inside of a collection tank having one end as an air intake port and the other end as an exhaust port, and dust is captured by the mist while the mist is introduced. The dust is collected by the demister.

  Moreover, the dust collector for grain dryers shown in patent document 2 as another prior art is mentioned. In this dust collector, mist is discharged from the upper part of the water tank whose upper surface is open, dust is captured by the mist at the mixing part, and then flows down into the water tank together with the mist, and only air is discharged from the exhaust port. .

Japanese Patent Laid-Open No. 2005-000888 JP 2003-65676 A

  However, according to the wet dust collector of Patent Document 1, a demister must be provided, which becomes a factor that hinders the flow of air. Further, in Patent Document 2, since the mixing portion is narrow, it is difficult to say that dust is sufficiently captured by the mist, and the distance that the mist flows down to the water tank is short, and the mist may be discharged to the outside as it is. is there.

  Therefore, the present invention aims to increase the dust collection capability without providing a demister.

  1. In a dust collector that takes in air containing dust from the inflow port, captures the dust by bringing the mist into contact with the air, and discharges the air separated from the dust from the discharge port. (1) Water tank filled with water And (2) a spray nozzle for spraying mist on the air containing dust taken in from the inlet, and (3) a partition for dividing the inside of the water tank into a plurality of regions. There is provided a dust collecting device provided with a plate and (4) an air passage for allowing air to pass through each region of the divided water tank.

  2. The air passage is configured in an arch shape. The dust collector described in 1. is provided.

  3. The partition plate is provided so as to be in contact with the upper and lower surfaces of the air passage, and the partition plate provided on the lower surface side of the air passage is in contact with a front end portion of the air passage. Or 2. The dust collector described in 1. is provided.

  According to the present invention, since dust and water can be caused to flow into the water tank without providing a filter device such as a demister after the dust is captured by the mist, the device can be simplified.

  Further, by providing an arch-shaped air passage, a vortex of airflow can be generated inside the water tank. As a result, dust and mist are sufficiently mixed and dust collection capability is increased, so that dust and water can flow down to the water surface.

  The dust collector will be described in detail with reference to the drawings. FIG. 1 is an overall view of the dust collector. FIG. 2 is a top view of the dust collecting portion of the dust collector. FIG. 3 is an enlarged view of the partition plate and the air passage.

  The dust collector 1 includes a water tank 1, partition plates 2 </ b> A, 2 </ b> B, air passages 3 </ b> A, 3 </ b> B, a spray nozzle 4 that sprays mist on the air, and a fan 9 provided at the discharge port 7. It is assumed that the basic configuration is provided.

  Water is filled inside the water tank 1, and the spray nozzle 4 sprays water from the upper part of the water tank to generate mist. Mist may be generated directly from the spray nozzle, but it may sprinkle violently toward the surface of the water and the water splashes to create water mist. The mist is filled to the inside of the aquarium 1. It is desirable to generate

  Since the fan 9 is attached to the discharge port 7 so as to suck out air, an air flow from the inflow port toward the discharge port is generated inside the water tank, and air containing mist and dust is contained in the water tank. Will be moved.

  By mixing the air and mist, the dust contained in the air contains water and increases its own weight. And by flowing down to the water surface as it is, dust is removed from the air.

  Dust that flows down to the surface of the water settles down and accumulates at the bottom of the water tank. A belt conveyor 5 is provided at the bottom, and accumulated dust is pulled up from the water tank 1 and removed. Water in the water tank can be appropriately circulated with the purification device.

  The inside of the water tank 1 is divided into a plurality of regions by partition plates 2A, 2B. The air passages 3A and 3B are provided in a direction orthogonal to the partition plates 2B and 2C in order to allow air to pass through the respective regions from the inflow port to reach the discharge port. Since the partition plates 2B and 2C reach from the water tank top plate to the air passage 3A, and the partition plates 2D and 2E reach from the air passage 3B to below the surface of the water, the air flows into the adjacent area unless passing through the air passage 3. You can't do that. In addition, the number of partition plates and the number of ventilation paths are changed as appropriate, and the length from the inlet to the outlet can be determined. The air hits the partition plate 2A, is guided to the discharge port 7, and is discharged to the outside.

  The partition plates 2 </ b> B and 2 </ b> C provided so as to be in contact with the upper surface side of the air passage 3 </ b> A are provided in the vertical direction from the top plate of the water tank 1. It is provided so that a space is formed between the air passage 3A, the partition plates 2B and 2C, and the water tank 1 top plate, and is preferably provided near the center of the upper surface of the passage 3A. The air passages 3A and 3B have an arch shape, and it is possible to provide bolts as shown in FIG. 3 so that the diameter of the arc is variable. It is also possible to provide this bolt in the air passage 3A in the same manner.

  In this way, the shapes of the partition plates 2B and 2C and the air passage 3A combine to generate an air current vortex between the water tank top plate and the air passage 3A as shown in FIG. That is, air hits the tip of the air passage 3A and directly hits the partition plates 2B and 2C along the upper surface of the air passage 3A. Then, after staying as a spiral airflow, the air enters the air passage 3. By causing the stagnation of air in this way, the mist ejected from the spray nozzle 4 and the air containing dust are mixed, so that the dust collection effect is enhanced.

  Further, the partition plates 2D and 2E are provided so as to be in contact with the lower surface side tip of the air passage 3B. With this structure, the air hitting the partition plates 2D and 2E can enter the air passage 3 as it is. In addition, it is preferable to adjust the height of the partition plates 2D and 2E according to the water level so that water is not blocked and air does not enter the adjacent region without passing through the air passage 3. The height of the partition plate 2A can also be determined according to the water level.

1 is an overall view of a dust collector according to the present invention. It is a top view of the dust collection part which concerns on this invention. It is an enlarged view of the partition plate and ventilation path which concern on this invention.
