In an air cleaner having a structure for purifying contaminated air in a factory or the like with cleaning water, it is important to efficiently bring the contaminated air into contact with cleaning water, and the method has been studied repeatedly. As one of the methods, as a result of trial and error, it was found that air and water can be efficiently contacted by arranging a plurality of cones with through holes in a plane and stacking them. In view of this, an air cleaner having a simple structure utilizing this method has been invented.

An object of the present invention is to provide an air cleaner that can efficiently purify contaminated air in a factory or the like with water and has a simple structure.

That is, according to the first aspect of the present invention, a plurality of conical cells having a plurality of through-holes and a plurality of conical cells arranged in the same plane are arranged on the same plane. It is a conical cell type scrubber constructed by stacking.

The through holes are holes through which washing water and air pass, and increase the chance of contact between air and water through a large number of through holes. The cone is composed of a bottom surface, a vertex, and a side surface connecting the vertex, but the hollow cone means a hollow cone without a bottom surface. It is used with the apex of this cone facing down and the bottom surface facing up. The reason why the apex portion is cut and opened is to allow air and water to pass through the opening portion with the open apex portion facing downward.

The apex portion of the cone having a large number of through holes is cut and opened, and the open apex portion is down and the bottom surface is up is referred to as a conical cell. A plurality of the conical cells arranged in the same plane and the stacked ones were used as a conical cell type scrubber.

Inside the conical cell is a hollow auxiliary cone with a number of through holes. The hollow is as described above. This auxiliary cone remains conical without cutting the apex. A screw-shaped blade is placed on the auxiliary cone, and the flow direction of air and water is changed to bring the air and water into contact with each other. The use of screw-type blades means that mechanical fixing is not performed.

Subsequently, the third invention is the conical scrubber of either the first invention or the second invention in which a magnet is fixed to the apex opening of the conical cell.

Air and water concentrate on the apex opening of the conical cell. A magnet is fixed here, and the effect in the water cluster decomposition | disassembly by the magnetic force mentioned above is anticipated. The contaminated air contains not only dust but also malodorous substances. This malodorous substance and the like can be efficiently collected by the cluster-decomposed water.

Subsequently, according to a fourth aspect of the present invention, a shower device for washing water is attached above the conical cell type scrubber of any one of the first to third aspects, a gas-liquid separation chamber is connected under the conical cell type scrubber, and A water storage chamber is provided under the partition, and the contaminated air from the duct passes through the shower of cleaning water, and then passes through the conical cell type scrubber together with the cleaning water. The cleaning water and air are separated in the gas-liquid separation chamber. Then, the purified air is discharged from the exhaust fan, the washing water flows down to the water storage chamber, and the conical cell type air washer retransmits the washing water in the water storage chamber to the shower facility.

A fourth invention is an air cleaner using the conical cell type scrubber of any one of the first to third inventions. The contaminated air blown from the duct passes under the shower of washing water and passes through the conical cell scrubber according to any one of the first to third inventions together with the washing water. In the process, the contaminated air is washed with washing water. Washing water and washed air are separated in the gas-liquid separation chamber under the conical cell type scrubber, and the washed air is discharged by the exhaust fan, and the washing water is a water storage chamber under the gas-liquid separation chamber. Then, the cleaning liquid in the water storage chamber is retransmitted to the shower facility.

Representative examples of the present invention are shown below.

  FIG. 1 is a conical cell of the first invention and its development. (A) is a perspective view and (B) is a development view. The conical cell 3 is manufactured by punching metal in the same manner as the auxiliary cone 4 and the blade plate 5 described later. The punching metal is a general term for products obtained by punching a plate mainly made of a metal material by pressing, and this hole is a through-hole 31 of a conical cell. This punching metal was manufactured by cutting with a laser beam and seam welding in accordance with the development of FIG. The use and manufacturing method of the punching metal is not limited to this, and a conical cell with a through-hole that can contact contaminated air and cleaning water is sufficient.

FIG. 2 shows a screw-type vane plate 5 according to the second invention. A substantially circular punching metal is cut from four directions except for the central portion, and is bent to form a blade plate 5. This vane plate 5 changes the direction of air and washing water and at the same time lengthens the stroke to increase the contact efficiency of air and washing water, and the folding angle and the folding direction are arbitrarily processed. In addition, the blade 5 should just perform said function, and the shape etc. are not ask | required.

FIG. 3 is a view in which the auxiliary cone 4 is placed in the conical cell 3 and the blade plate 5 is placed thereon.
The contaminated air blown from the duct comes into contact with the cleaning water from the shower while passing through the blade 5 auxiliary cone 4 and the cone cell 3 to be purified.
Next, the malodorous substance etc. contained in the polluted air are efficiently removed by the cluster-disassembled washing water hitting the magnet 6 attached to the apex opening of the conical cell 3. The magnet 6 has a cylindrical shape, and contaminated air and washing water also pass through the central cavity 61 thereof.

FIG. 4 is a transverse sectional view of the conical cell 3. The auxiliary cone 4 is placed at the same height as the conical cell 3 so that air and washing water can easily contact through the through hole 41 of the auxiliary cone. The vane plate 5 is placed on the auxiliary cone 4.

FIG. 6 is an overall view of the conical cell type air cleaner 1. In FIG. 6, the blade 5 and the auxiliary cone 4 are omitted. The contaminated air blown from the duct 10 passes under the washing water shower facility 7 and then passes through the through holes 31 and 41 of the blade plate 5 and the auxiliary cone 4 together with the washing water, and further through the cone cell. It passes through 31 and contacts the cleaning water efficiently. Further, the washing water hits the magnet 6 and collects malodorous components and the like contained in the contaminated air due to activation of water by cluster decomposition. This operation is repeated, and in FIG. 7, since the conical cells 3 are stacked in six stages on a plurality of planes, the contaminated air is purified 6 times repeatedly. The air and water that have flowed down to the gas-liquid separation chamber 8 are separated, and the air is discharged by an air exhaust 82 attached to the gas-liquid separation chamber 8. The purified air may be returned to the factory and reused. The cleaning liquid flows down to the water storage tank 9 below the partition wall 81, is sent to the cleaning water shower facility 7 through the cleaning water circulation pipe 92 by the cleaning water circulation pump 91, and is reused. In addition, when the cleaning water has a contamination level that exceeds a predetermined level, it is sent to a wastewater treatment facility, and fresh cleaning water is sent to the water storage tank 9 for use.

A conical cell having a large number of through-holes is expected to be in demand because air and water can be efficiently contacted and dust and malodorous substances in polluted air can be efficiently removed.
