The present invention relates to a deodorizer which can be applied to a food treatment plant, a livestock waste treatment plant, a sewage treatment plant, and various industrial sites where a high concentration of complex odors are generated. More specifically, the present invention relates to a vortex diffraction mixer deodorizer with high deodorization efficiency.

Deodorizers for deodorizing and purifying polluted air containing high concentrations of odor or harmful gases have been developed in various forms. This deodorizer mainly uses the principle of deodorizing the contaminated gas by contacting dispersed liquid particles or by using an adsorbent.

Applicant has also developed and patented Patent No. 689,620 for an ozone-supply diffraction type ultrasonic activated carbon adsorption tower purification apparatus in which an ozone generator, a diffraction plate, and an ultrasonic oscillator are installed in the activated carbon adsorption column purification apparatus to improve the purification efficiency.

In addition, the present applicant is provided with a gas circulation pipe for circulating a portion of the gas treated in the main body to the gas transfer pipe, to maintain a constant wind pressure of the gas flowing into the main body, to maximize the impin-jet effect (purification) It has been developed and patented as patent No. 844,178 to develop an efficient deodorizer.

Conventional deodorizers, including the patent invention, utilize the principle of removing odors in such a manner that all of the cleaning liquid made of water or a chemical liquid is sprayed through a nozzle, and the odor gas to be purged is contacted with the sprayed cleaning liquid. However, this prior art has some fatal flaws. One of them is to deodorize the odor gas with the sprayed cleaning solution, which makes it difficult to improve the purification efficiency. Second, the scale is formed by various contaminants in the diffraction plate or mixer plate installed therein. Secondly, in order to increase the contact area between the jetted cleaning liquid and the malodorous gas, the contact time is long and the volume of the apparatus includes a drawback. If the volume of the device is small, it also takes up a lot of area because a plurality of deodorizers must be installed in parallel.

In order to solve the problems of the conventional deodorizer as described above, the inventors deviate from the conventional principle of contacting the cleaning liquid particles injected through the injection nozzle with the gas particles of the odor gas, and the cleaning liquid moves in the vortex diffraction method.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

The present invention can improve the purification efficiency by passing the malodorous gas into the cleaning liquid layer moving in the vortex diffraction method, and the compactness of the device can be reduced, and the scale is not formed on the internal equipment parts. The effect of the invention is to provide a new high efficiency vortex diffraction mixer deodorizer further comprising an opening and closing member to form a cleaning liquid layer that moves in a vortex diffraction manner by the wind pressure of the malodorous gas supplied from the lower portion of the.

The present invention relates to a deodorizer which can be applied to a food treatment plant, a livestock waste treatment plant, a sewage treatment plant, and various industrial sites where a high concentration of complex odors are generated, and relates to a vortex diffraction mixer deodorizer with high deodorization efficiency.

The vortex diffraction mixer deodorizer having high deodorization efficiency according to the present invention has a main body 100 for purifying odor gas therein, a fan 10 for injecting odor gas at a constant pressure in the lower part of the main body, and one Vortex diffraction plate 40, which is composed of a cleaning liquid ejection pipe 42 and two or more perforated plates 41, and circulates the cleaning liquid by a pump 30 to form the cleaning liquid layer 45, the upper part of the upper vortex diffraction plate Installed in the oil and water separator for oil and water separation device 60, and characterized in that consisting of the discharge port 70 for discharging the purified gas to the outside.

1 is a view showing a schematic configuration of a vortex diffraction mixer deodorizer according to an embodiment of the present invention.

A fan 10 is installed below the main body 100 to inject malodorous gas to be purified at a constant pressure. The capacity and wind pressure of the fan is controllable, which can be easily implemented by those skilled in the art.

The deodorizer according to the invention is equipped with one or more vortex diffraction plates 40. In FIG. 1, two vortex diffraction plates 40A and 40B are shown in two stages up and down. Each vortex diffraction plate 40 is composed of one cleaning liquid jet pipe 42 and two or more perforated plates 41, and the cleaning liquid is circulated by the pump 30 to form the cleaning liquid layer 45.

FIG. 2 is a schematic sectional view showing the configuration of the vortex diffraction plate 40A or 40B of FIG. 1, and FIG. 3 is a schematic perspective view showing the perforated plate 41 used for the vortex diffraction plate 40 of FIG.

In FIG. 2, the first perforated plate 41a is positioned at the lower end of the vortex diffraction plate 40, the cleaning liquid ejection pipe 42 is positioned thereon, and the second perforated plate 41b is again positioned thereon. The third perforated plate 41c is further installed on the second perforated plate. The spacing between the perforated plates 41a, 41b, 41c and the spacing between the cleaning liquid jet pipes 42 are not kept in close contact with each other so that the cleaning liquid moves in a vortex diffraction manner. In FIG. 1, two perforated plates 41 constitute a vortex diffraction plate 40, while in FIG. 2, three perforated plates 41 constitute a vortex diffraction plate 40. In FIG.

The perforated plate 41 of FIG. 3 is preferably made of synthetic resin such as PE and PVC. The perforated plate has a thickness of about 1 cm, and the cylindrical holes 411 having a diameter of 5 to 10 mm are regularly arranged. Through this hole, the malodorous gas moves from the lower part to the upper part, and the cleaning liquid is sprayed and dispersed to the upper part. The perforated plates 41a, 41b, 41c stacked while maintaining a constant distance from each other are installed so that the holes 411 are arranged in a zigzag without being completely coincident with each other so that the cleaning liquid is vortex diffracted.

The washing liquid used in the present invention includes water, an acid solution, an alkaline solution and the like. The type of the cleaning liquid should be selected in consideration of the type of contaminated gas or the chemical reaction that may occur in the deodorizer, which can be easily carried out by those skilled in the art. Perforated plates can be made of iron or stainless steel in addition to synthetic resins such as PE and PVC. However, if the cleaning solution is an acid solution or an alkaline solution, the problem of corrosion due to them should be considered.

When two or more sets of the vortex diffraction plates 40 are installed, an overflow tube 50 is formed to circulate each of the cleaning liquids, and the separate cleaning liquid tanks 20 are not mixed with each other. Is provided.

The vortex diffraction plate 40 is made of a perforated plate 41 made of perforated holes, and if the cleaning liquid layer 45 having a predetermined thickness is present thereon, the cleaning liquid falls down by the load. However, at this time, since the odor air is blown by the strong wind pressure by the fan 10 from the lower side so that the cleaning liquid does not fall, the cleaning liquid does not fall and forms the cleaning liquid layer 45 having a predetermined thickness. In the case where two or more sets of vortex diffraction plates are installed, the cleaning liquids overflowing the vortex diffraction plate 40A are dropped through the overflow pipe 50A to each separated cleaning liquid tank 20A so as not to be mixed with each other. The cleaning liquid collected and overflowed to the vortex diffraction plate 40B is collected into each separate cleaning liquid tank 20B so as not to fall through the overflow pipe 50B and be mixed with each other and to pump 30A and 30B, respectively. Circulated by

FIG. 5 is a schematic plan view of the cleaning liquid jet pipe 42 inserted into the vortex diffraction plate 40 of FIG.

The cleaning liquid ejection pipe 42 should always be located between the first and second perforated plates 41a and 41b as a means for ejecting the cleaning liquid to the vortex diffraction plate. Although FIG. 5 shows the cleaning liquid jet pipe to one embodiment, the present invention is not limited thereto, and may be changed to another shape or shape by those skilled in the art. Since the cleaning liquid jet pipe 42 of the present invention is not a concept of injecting the cleaning liquid in a conventional deodorizer, but a concept of supplying the cleaning liquid to the vortex diffraction plate, the deodorizer of the present invention is substantially free of a nozzle (Nozzle) as compared to the conventional nozzle deodorizer. nozzleless) can be called a deodorizer.

On top of the vortex diffraction plate 40, one or more conventional four mixer wind direction plates 43 are provided to allow the cleaning liquid to move in the vortex diffraction method. 2 and 4 show a mixer wind vane 43, which is provided on the upper perforated plate to form a vortex when gas and liquid are dispersed from the bottom to the top. Four mixer wind direction plates are shown in FIG. 4, whereby the vortices can be formed in the cleaning liquid layer 45, thereby improving the deodorizing effect.

In order to assist the vortex diffraction movement of the cleaning liquid, a screw thread or a double helical groove is formed in the inner wall of the hole 411 formed in the perforated plate 41. FIG. 10 is a schematic perspective view showing a double spiral groove 481 formed in the inner wall of the hole 411 formed in the perforated plate 41 of FIG.

In the present invention, by providing two or more sets of the vortex diffraction plate 40 up and down, the deodorizing efficiency can be increased because the purification is carried out in two stages or more, thereby eliminating the need to arrange the deodorizers in parallel. It can be. Although two or more sets of vortex diffraction plates have been described herein, two sets or three sets are usually preferred.

Glass-blocked windows 90 are provided on each side of the vortex diffraction plate so as to confirm the operation of the deodorizer.

An oil / water separator 60 is installed on the uppermost vortex diffraction plate to separate the liquid and the gas, and the separated gas is discharged to the outside as a purified gas, and the separated liquid is introduced and circulated inside. The oil / water separator is a member widely used in a conventional deodorizer. The purified gas is discharged to the outside through the discharge port 70. The discharge port is provided with a measuring port 71 that can measure the odor degree of the discharged gas, which can be easily found in the conventional deodorizer.

It is very important that the deodorizer of the present invention maintain a cleaning liquid layer of a certain thickness on the vortex diffraction plate by a constant wind pressure of the contaminated gas. If this wind pressure is not sufficient, the cleaning liquid will not form the cleaning liquid layer 45 and fall down. In order to solve this problem, in the vortex diffraction mixer deodorizer of the present invention, an opening / closing member capable of opening and closing a part of the vortex diffraction plate 40 at the uppermost stage so that the cleaning liquid layer is formed by the wind pressure of the malodorous gas supplied from the lower part of the apparatus main body. It further includes.

FIG. 6 is a schematic perspective view showing a state where a part of the uppermost vortex diffraction plate 40A is blocked by the iron ball 412. The upper portion of the vortex diffraction plate 40 is composed of a perforated plate 41, and serves to block a portion of the perforated plate by inserting an appropriate amount of iron beads 412 having a diameter larger than the perforated hole 411. For example, when the iron bead corresponding to 1/2 of the perforated hole is put in, even if the pressure decreases to 1/2, since the constant pressure is maintained inside the deodorizer, the washing liquid layer can be maintained at a constant thickness. When the wind pressure is stronger, the iron ball blocking the hole is lifted upwards, which acts as a kind of check valve. When the diameter of the hole is 6 mm it is possible to use an iron ball having a diameter of 8 mm, which can be easily carried out by those skilled in the art.

The opening / closing member of FIG. 7 forms a + -shaped cutout groove 413 at a position corresponding to the center of the hole 411 in the synthetic sheet at a predetermined thickness so that the cutout groove serves as a check valve.

FIG. 8 is a schematic perspective view showing the opening and closing member 430 of another embodiment capable of blocking a part of the uppermost vortex diffraction plate 40A. The opening and closing member of FIG. 8 forms a U-shaped incision groove 414 having a predetermined thickness at a position corresponding to the hole 411 in the synthetic sheet so that the incision groove serves as a check valve.

FIG. 9 is a schematic perspective view showing an opening and closing member 440 of another embodiment capable of blocking a portion of the uppermost vortex diffraction plate 40A. The opening and closing member of FIG. 9 has a predetermined thickness to form a U-shaped incision groove 415 at a position corresponding to a row of holes 411 in the synthetic sheet so that the entire incision groove serves as a check valve.
