DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention is, for example, to a gas-liquid contact apparatus for removing or denatured odors in the air, bacteria and NO _X, etc. is contacted with the liquid.

[0002]

2. Description of the Related Art Conventionally, as a device for contacting gas and liquid for the purpose of removing impurities in the air or the like, a square duct is provided in a passage through which gas flows, and a liquid is sprayed into the square duct. There has been known a device for separating a gas and a liquid by guiding a mixture of a liquid and a gas passing through a square duct to a scrubber filled with a Raschig ring or the like.

However, in such an apparatus, since the gas and the liquid flow in the same direction and are actually in parallel contact,
Since partial contact is made without complete contact, there is a problem that the efficiency of removal of impurities and denaturation in gas is poor. In addition, since dust and the like in the gas are introduced into the scrubber together with the mixture of the gas and the liquid, the dust and the like are clogged in the scrubber and the contact efficiency between the gas and the liquid is deteriorated. Therefore, the scrubber must be cleaned frequently. There was a problem to be had.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such a point, and makes it possible to bring a gas and a liquid into contact with high efficiency, and to include a dust and a liquid in the treated gas. It is an object of the present invention to provide a gas-liquid contact device that hardly mixes.

[0005]

Configuration of the present invention along above object In order to achieve the above, the internal rotating freely rotating body to the main body casing housing the liquid is furnished to, the rotating body, a plurality of the opposing sealing plates connected by a long bolt, the said bolt of said sealing plates fitted multiple alternating with gas-liquid contact ring having an opening in the center of the spacer and the disc, through the spacer
A gas passage is formed between the adjacent gas-liquid contact rings , and the gas introduced from the inflow port formed in the main body casing is supplied to the outside of the gas-liquid contact ring.
Wherein the liquid is atomized by the rotation of the rotating body, passed through the gas passage while flow contact as pass each other, the ring communicating of the gas-liquid contact ring to be sprayed toward
The casing is discharged through an outlet formed in the casing through the shape portion .

[0006] In short, the present invention is based on the fact that by rotating a number of gas-liquid contact rings arranged with a spacer interposed therebetween, the liquid adhering to the gas-liquid contact ring is mist-shaped toward the outside of the gas-liquid contact ring by centrifugal force. Since it is sprayed, the contact with the gas becomes countercurrent contact, so the contact ratio of gas and liquid is remarkably improved, and dust and the like in the gas collide with the mist by centrifugal force against the inner wall of the main body casing. The gist of the invention is that the amount of dust and the like mixed into the treated gas is extremely reduced due to the adhesion.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. A gas inlet 1 is formed at an upper end of the cylindrical main casing 3, and a gas discharge side of the main casing 3 is
The body cover 4 having the gas outlet 2 formed in the center is the bolt 1
6. Incidentally, reference numeral 17 in the figure denotes a bracket for supporting the main body casing 3. The rotating body 19 provided in the main body casing 3 has six long stud bolts 14 equally distributed among the disc-shaped sealing plates 15 and 9 disposed therethrough. The long stud bolt 14 has a ring-shaped gas-liquid contact ring 11.
And a large number of disk-shaped spacers 10 alternately fitted to each other.
Are tightened and fixed by spring washers 12 and nuts 13 at the positions of the disc-shaped seal plates 15 and 9. Although the ring-shaped gas-liquid contact ring 11 is fitted to six long stud bolts 14, the spacer 1
0 is fitted into each of the long stud bolts 14, so that a slit 22 serving as a gas passage is formed between the spacers of the adjacent long stud bolts 14, as shown in FIG. ing.

In the center of the seal plate 15 on the gas outlet side,
A cylindrical pipe shaft 6 is welded, and the pipe shaft 6 is sealed via a bearing 8 to the gas discharge port 2 so as to be freely rotatable forward and backward. The power shaft 5 is welded to the center of the other seal plate 9, and the power shaft 5 is
An opening 20, which is formed in a side portion of the main body casing 3 and protrudes inward in a cylindrical shape, is sealed via a bearing 7 so as to be rotatable forward and backward. With such a configuration, the inside of the main body casing 3 is kept in a sealed state with the outside.

In the figure, reference numeral 18 denotes a liquid to be brought into contact with a gas, and the type of the liquid may be appropriately selected and used according to the purpose of the gas-liquid contact. As shown in the figure, when the rotating body 19 rotates, the width between the inner and outer diameters of the gas-liquid contact ring 11 is completely reduced only at the lower end of the gas-liquid contact ring 11 as shown in the figure. It is recommended that the amount be soaked in water.
In the present invention, since the gas-liquid contact ring 11 and the spacer 10 are fitted to the long bolt 14, the thickness, number or size of the fitted spacer 10 and the gas-liquid contact ring 11 can be freely changed. Since the slit width 22 and the number of slits through which the gas passes can be changed, the passing speed of the gas at a constant pressure can be changed. Further, in the present invention, the gas-liquid contact ring 11 and the spacer 10 are fitted alternately. However, this does not necessarily mean that the gas-liquid contact ring 11 and the spacer 10 are fitted alternately. They can be fitted together.

[0010]

Next, the operation of the present invention configured as described above will be described. First, the liquid 19 is poured into the main body casing 3 as shown in FIG.
As shown in FIG. 2, only the lower end of the gas-liquid contact ring 11 is accommodated so that it is completely immersed. Next, the motor (not shown) is rotated to rotate the power shaft 5 and rotate the rotating body 19. The rotation speed of the rotating body depends on the properties of the gas,
It can be appropriately selected according to the flow rate and the like. When the gas-liquid contact ring 11 of the rotating body rotates by contacting the liquid 18, the liquid attached to the gas-liquid contact ring 11 becomes mist by centrifugal force and moves from the inside of the gas-liquid contact ring 11 to the outside. Released.

In this state, gas is introduced from the gas inlet 1. The gas introduced into the main body casing 3 comes into countercurrent contact with the mist of the liquid and passes through the slit 22 between the gas-liquid contact rings from the outer diameter toward the inner diameter as shown in FIG. In the process of passing the gas through the slit 22, gas-liquid contact is completely completed due to turbulence with the mist. Further, dust and the like in the gas collide with and adhere to the inner wall of the main body casing 3 together with the mist due to the centrifugal force. The gas that has passed through the slit 22 is introduced into the center of the rotating body, and is discharged from the gas discharge port 2. Since the mist is hardly present at the center of the rotating body, the treated gas contains almost no mist as well as dust.

[0012]

As described above, according to the present invention, gas and liquid mist come into countercurrent contact in a violently turbulent state, so that gas-liquid contact can be performed perfectly.
Since dust and the like in the gas collide with and adhere to the inner wall of the main casing together with the mist, the dust after gas-liquid contact hardly exists in the gas-liquid contacting device of this kind, which is completely seen in this type of conventional gas-liquid contact device. Has no noticeable effect. In addition, since the gas-liquid contact ring and the spacer are configured to be removably fitted to the long bolt, the slit width through which the gas passes can be adjusted according to the nature and flow rate of the gas. Can be obtained.
