Abstract

PURPOSE:To make gas-liquid contact perfect and to prevent dirt, etc., from being mixed into treated gas by internally installing a rotor which is freely rotatable in the forward and backward directions and has a lot of gas-liquid contact rings arranged with a spacer inserted between them in a body casing contg. liquid inside. CONSTITUTION:A body casing 3 contains a liquid 18 by such amount that only the lower end of gas-liquid contact rings 11 is completely immersed in the liquid and a rotor 19 is turned with the revolution selected according to the property and flow rate of gas. When the gas-liquid contact rings 11 of the rotor 19 come into contact with the liquid 18 and are turned, the liquid stuck to the gas-liquid contact rings 11 is turned into a mist by centrifugal force, causing the mist to be discharged from the inside to the outside of the gas-liquid contact rings 11. In this state, gas is introduced from a gas inflow port 1 to give it countercurrent contact with the liquid mist and in a process of passing through slits between the gas-liquid contact rings 11 from the outer diameter to the inner diameter, the gas-liquid contact is perfectly finished by the turbulence with the mist to discharge the gas from a gas discharge port 2 in the center of the rotor 19, and dirt, etc., in the gas strikes on and is stuck to the inner wall of the body casing 3 together with the mist by centrifugal force.

Description

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 bringing gas and liquid into contact with each other for the purpose of removing contaminants in the air, a square duct is arranged in a passage through which gas flows, and the liquid is sprayed into the square duct. However, there is known a device that guides a mixture of liquid and gas that has passed through the square duct to a scrubber filled with Raschig rings or the like to separate the gas and liquid.

However, in such a device, the gas and the liquid flow in the same direction and are actually in parallel contact with each other.
There is a problem in that the efficiency of removing contaminants in the gas and the denaturing efficiency are poor, because partial contact occurs instead of complete contact. Not only that, dust and the like in the gas is introduced into the scrubber together with the mixture of the gas and the liquid, so that the dust and the like are clogged with the scrubber and the contact efficiency between the gas and the liquid is deteriorated, and therefore the scrubber must be frequently cleaned. There was a problem to be solved.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such a point, and makes a gas and a liquid come into contact with each other with high efficiency, and the treated gas contains dust and liquid. It is an object of the present invention to provide a gas-liquid contact device in which almost no water is mixed.

[0005]

According to the structure of the present invention which meets the above-mentioned object, a body casing for containing a liquid is internally provided with a rotatable body capable of rotating in the normal and reverse directions. A long bolt, and a plurality of spacers and gas-liquid contact rings are alternately fitted to the bolts between the seal plates, and the spacers are fitted to the bolts so that the spacers between the adjacent bolts are It is configured to form a gas passage, and passes through the gas passage while countercurrently contacting the gas introduced from the inlet formed in the main body casing with the liquid misted by the rotating body in the casing. And is discharged from the outlet formed in the casing.

In summary, according to the present invention, by rotating a large number of gas-liquid contact rings arranged with a spacer interposed therebetween, the liquid attached to the gas-liquid contact ring is formed into a mist by centrifugal force toward the outside of the gas-liquid contact ring. Since it is sprayed, the contact with gas becomes countercurrent contact, so the contact rate of gas-liquid is significantly improved, and dust in the gas collides with the inner wall of the main casing together with the mist due to centrifugal force. The gist is that the amount of dust and the like mixed in the treated gas is extremely reduced because of the adhesion.

[0007]

Embodiments of the present invention will now be described with reference to the drawings. A gas inlet 1 is formed at the upper end of the cylindrical main body casing 3, and a gas outlet side of the main body casing 3 is
The body cover 4 having the gas discharge port 2 formed in the center is the bolt 1
It is fixed by 6. Reference numeral 17 in the drawing denotes a bracket that supports the main body casing 3. The rotating body 19 installed in the main body casing 3 has six long stud bolts 14 equally distributed between the disc-shaped seal plates 15 and 9 arranged to face each other. A ring-shaped gas-liquid contact ring 11 is attached to the long stud bolt 14.
And the disc-shaped spacer 10 are alternately fitted to each other, and the long stud bolt 14
Is clamped and fixed by the spring washer 12 and the nut 13 at the positions of the disk-shaped seal plates 15 and 9. The ring-shaped gas-liquid contact ring 11 is fitted to the six long stud bolts 14, but the spacer 1
No. 0 is fitted in each long stud bolt 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.

At 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 in the gas discharge port 2 so as to be rotatable in the forward and reverse directions. The power shaft 5 is welded to the center of the other seal plate 9, and the power shaft 5 is
An opening 20 projecting inward from the side portion of the main body casing 3 in a cylindrical shape is sealed via a bearing 7 so as to be rotatable in the forward and reverse directions. With this configuration, the inside of the main body casing 3 is maintained in a sealed state with the outside.

Reference numeral 18 in the drawing denotes a liquid to be brought into contact with gas, and the type of liquid may be appropriately selected and used according to the purpose of gas-liquid contact. As shown in the figure, the amount of liquid contained in the main body casing 3 is such that the width between the inner and outer diameters of the gas-liquid contact ring 11 is complete only at the lower end of the gas-liquid contact ring 11 when the rotating body 19 rotates. It is recommended that the amount be soaked in.
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 spacer 10 and the gas-liquid contact ring 11 to be fitted can be freely changed. Since the slit width 22 and the number of slits through which the gas passes can be changed, the passage 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, but one or both of them are not fitted alternately, but one or both of them are alternately fitted. It does not matter if they are fitted together.

[0010]

Next, the operation of the present invention constructed as above will be described. First, the liquid 19 is placed in the body casing 3 as shown in FIG.
And, as shown in FIG. 2, only the lower end of the gas-liquid contact ring 11 is accommodated so that it is completely immersed. Then, a motor (not shown) is rotated to rotate the power shaft 5 and rotate the rotating body 19. The rotation speed of the rotating body is
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 in contact with the liquid 18, the liquid adhered to the gas-liquid contact ring 11 becomes a mist due to centrifugal force, and the gas-liquid contact ring 11 moves from the inside to the outside. Is released.

In this state, gas is introduced from the gas inlet 1. The gas introduced into the main body casing 3 makes 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. As the gas passes through the slit 22, the gas-liquid contact is completely completed due to the turbulent flow with the mist. In addition, dust and the like in the gas collide with the inner wall of the main body casing 3 and adhere 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. Mist hardly exists in the central portion of the rotating body, so that not only dust but also mist is hardly mixed in the treated gas.

[0012]

As described above, according to the present invention, the gas and the liquid mist come into countercurrent contact with each other in a violent turbulent state, so that the gas-liquid contact can be perfectly achieved.
Since dusts and the like in the gas collide with the inner wall of the main body casing along with the mist and adhere to them, there is almost no dust or the like in the gas after the gas-liquid contact, which is completely seen in this type of conventional gas-liquid contactor. Has no noticeable effect. Further, since the gas-liquid contact ring and the spacer are configured to be detachably fitted to a long bolt, the slit width through which the gas passes can be set to an optimum gas passage speed depending on the nature and flow rate of the gas. Can be obtained.
