[Action]

 Water is sprayed from above into the dust collection chamber from a shower nozzle installed in the upper space of the first partition plate, transmitted through the filter material in the dust collection chamber and made to flow down from the child plate of the cage, and dust is contained from the air inlet port containing dust. Air is introduced and the direction is changed from ascending to descending in the space where the shower nozzle is installed, and then the direction is changed from descending to ascending on the upper surface of the inclined plate and discharged from the air discharge port. In the dust collection room, dust in the air containing dust is blocked by the filter material and is contained in the sewage, so-called contaminated water that flows into the wastewater settling tank through the slant plate and the sludge plate and bellows. It flows into the settling tank. Further, the contaminated water flowing along the upper surface of the inclined plate from the inclined upper end of the inclined plate pushes up the bellows and flows into the dirty water settling tank.

In the first dust collecting chamber 7 and the second dust collecting chamber 8, stainless cutting chips of various shapes such as a spiral form an air circulation space as a filter material 24 up to the upper end portion of the first partition plate 5. The filter material 24 is stored in the third dust collecting chamber 9 so as to form an air circulation space up to the lower side of the air discharge port 3 as well.

A support leg 25 is attached to the lower surface of the vertical tubular container 1 so that the vertical tubular container 1 can be installed on a mount or the like by the support leg 25. Is supported by the support leg 25 via a fixing plate 26. In FIG. 1, 27 is a water level gauge, 28 is an inspection port, 29 is a ceiling opening lid of the vertical cylindrical container 1, and 30 is a dust air supply pipe whose one end is connected to an axial fan. Dust-containing air is introduced into the vertical cylindrical container 1, and 31 is a valve provided at the wastewater discharge port 17.

The operation will be described below with reference to FIG.

The pump 22 is driven to supply the water in the filtration tank 11 to the shower nozzle 20 via the water supply pipe 23 and the water supply pipe 21 as shown by the solid arrow, and the shower nozzle 20 causes the first dust collection chamber 7 to flow. Water is sprayed radially from above to the second dust collecting chamber 8 as shown by the broken line, and the sprayed water passes between the filter materials 24 in the first dust collecting chamber 7 and the second dust collecting chamber 8 to form a cage. The dust-containing air is introduced from the dust supply pipe 30 through the dust-introducing air inlet 2 into the space below the cage-like plate 4 at the bottom of the first dust collecting chamber 7.

The dust-containing air introduced into the lower part of the cage plate 4 which is the bottom of the first dust collecting chamber 7 is the water surface of the sewage settling tank 10, the inclined lower end portion of the inclined plate 13, and the first partition. Since the bellows 15 and the protruding portion of the cage of the board 5 from the child board 4 are shielded from the lower spaces of the second and third dust collecting chambers 8 and 9, the board shape of the first partition board 5 is formed. Along with the protruding portion from the plate 4 and the bellows 15 attached to the protruding portion, as shown by the white arrow, the inside of the first dust collecting chamber 7 rises through the void portion of the child plate 4 of the cage.

That is, the dust-containing air that has entered the first dust collection chamber 7 from the dust air supply pipe 30 collides with the water jetted from the shower nozzle 20 dripping from the filter material 24 and the filter material 24 while The dust that has passed through the materials 24 and rises while separating the dust, passes through the upper communication space between the first dust collecting chamber 7 and the second dust collecting chamber 8 and reaches the second dust collecting chamber 8, and the dust separated in one direction. Together with the water dripping between the filter materials 24 in the first dust collecting chamber 7 flows through the child board 4 of the cage as shown by the broken line arrow into the sewage settling tank 10.

The air purified in the first dust collecting chamber 7 collides with the filter material 24 together with the water sprayed from the shower nozzle 20 in the second dust collecting chamber 8 as shown by the white arrow, and the filter material 24 The air that has passed through the chamber and descends while further separating the dust, and the air purified in this way is redirected by the inclined plate 13 and flows through the inside of the third dust collecting chamber 9 to the filter material 24 as indicated by the white arrow. While colliding, it passes through between the filter materials 24, rises while separating dust and water, and is sucked by the fan 19 from the air discharge port 3 and discharged to the atmosphere.

As described above, the dust-containing air from the dust air supply pipe 30 collides with the filter material 24 in the first, second and third dust collecting chambers 7, 8 and 9 while whitening out the space between the filter materials 24. Since it passes through as indicated by the arrow, the passage distance becomes longer, and the dust separation is performed stepwise and efficiently.

The dust separated in the second dust collecting chamber 8 flows down to the inclined plate 13 through the child-like plate 4 of the cage together with the dripping water as shown by the broken line arrow, and in the third dust collecting chamber 9 The separated dust and water are dropped onto the inclined plate 13 as indicated by the broken line arrow, and the dust-containing water (contaminated water) that reaches the inclined plate 13 as described above flows along the inclined plate 13 while converging. Is pushed up to flow into the wastewater settling tank 10.

The dust-containing water that has flowed down into the sewage settling tank 10 is separated in the sewage settling tank 10 while it descends and rises as shown by the broken line arrow with the separation plate 14 as a boundary, and the separated dust is Sediment is deposited on the bottom of the sewage settling tank 10 and is discharged and collected as sewage from the sewage discharge port 17 through the valve 31. The supernatant of the sewage settling tank 10 passes through the plate member 12 and reaches the filtration tank 11 as indicated by the broken line arrow. The water thus stored in the filtration tank 11 is jetted from the shower nozzle 20 by the pump 22 through the water supply pipe 23 and the water supply pipe 21. Therefore, the process of jetting water from the shower nozzle 20, collecting in the wastewater settling tank 10 and the filtration tank 11, and supplying the water to the shower nozzle 20 is repeated by the pump 22, and is in a so-called circulating state.

Since the filter material 24 in the first, second and third dust collecting chambers 7, 8 and 9 is in a state of being washed with water which is constantly flowing down, dust is attached to the filter material 24. Even if it is washed off, the filter material 24 will not be clogged.

Further, the water level of the filtration tank 11 and the inside of the vertical cylindrical container 1 are inspected by the water level gauge 27, and when the water in the filtration tank 11 is insufficient, the water is replenished.

It should be noted that the present invention is not limited to the illustrated and described embodiments, for example, the case where the lower end of the first partition plate 5 projects from the cage-shaped plate 4 has been described. If the lower end of No. 5 does not project, the bellows 15 is attached to the lower side of the joint between the lower end of the first partition plate 5 and the cage plate 4 either directly or via an attachment member to contain dust. Preventing air from being introduced into the lower space of the second and third dust collecting chambers 8 and 9, making the vertical cylindrical container 1 into a shape other than a cylinder, and A caster is provided so as to be movable, and a plurality of and odd number of dust collecting chambers other than three are formed in the upper vertical cylindrical container 1 so that dust-containing air is turned to pass through each dust collecting chamber. It is voluntary to gradually purify and discharge the waste by Of course, various modifications can be made without departing from the gist of the present invention.
