Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an odor eliminating device,

The present invention relates to a device for removing malodors generated from food waste, and more particularly, to a device for collecting odor generated during food waste disposal by corona discharge, The present invention relates to a device for removing malodors generated from food waste using a corona discharge capable of improving air pollution and solving the problem of air pollution.

In general, food waste left in a cafeteria or a foodservice facility contains a lot of water and is easily corrupted to generate a bad odor, which causes contamination of rivers and soils.

Even when such food waste is to be treated by incineration or disposal, there is a problem in that a large amount of food waste is generated at the place where food garbage is generated due to moisture contained in a large amount of food waste, and the processing of the leachate can not be performed smoothly .

In order to solve the above problems, there has been proposed a food waste treatment method in which food waste is efficiently fermented, dried and crushed and used as various organic fertilizer, etc. However, these methods also have various drawbacks.

Specifically, most of the conventional food garbage disposing apparatuses are capable of easily disposing of pulverized food waste by pulverizing, fermenting and drying the food garbage or using it as fertilizer or the like. According to the conventional food garbage disposal apparatus, When food waste containing a large amount of water is burned, pulverized, fermented and dried, it takes a long time for processing, and the generated odor can not be blocked, so that food waste disposal work is avoided.

In order to prevent the generation of such odors, a method of chemically treating food waste has been practiced. However, in this case, it is necessary to add a chemical to prevent the generation of odor, which is disadvantageous in that expensive food waste processing costs are consumed.

According to the conventional food garbage disposal apparatus, it is not only impossible to completely remove the moisture contained in the food waste, but also it is necessary to continuously treat the residue of the large amount of particles remaining after the food garbage disposal, Environmental problems exist.

Accordingly, there is a need for a new food garbage disposal technique which can reduce the generation of odor while ensuring the efficiency of the food garbage disposal process and shortening the processing time.

Next, the indicator S2 indicates the suction unit. The suction unit S2 is relatively small in particle and odor, which is solidified in the sorting unit S1 or does not fall down to the lower end of the sorting unit S1 because the particle is large Is sucked through the suction pipe 201 by the suction blower 200 and is transferred to the filtration unit S3 described below through the transfer pipe 202. [

Next, the reference numeral S3 designates a filtering unit. The filtering unit S3 is configured to filter the odor and noxious gas and dust, which have been sucked through the suction unit S2, through the filter 300 as shown in FIG. Filtration and dust collection.

The heat exchanging unit S4 exchanges the temperature of the high-temperature odor and noxious gas passing through the filtration unit S3 with the heat generated by the suction blower 200 by 40 ° C or lower .

As shown in FIG. 7, the inlet 400 receives a mixed gas of odorous and noxious gases such as volatile organic compounds (VOCs) or odorous gas through an inlet H from the outside, And is connected to the lower housing 530 of the corona reacting unit 500 by branching from the inflow pipe 410. The lower housing 530 of the corona reacting unit 500 is branched from the inflow pipe 410, And a branch pipe (411) communicably connected to the pipe.

The inflow pipe 410 has a pipe shape, one end connected to the external odor and noxious gas, the dust supply source, and the other end branched to extend to each branch pipe 411.

Although two tubes are shown as being branched in the example, three or more tubes may be used, and it is also possible that a plurality of tubes are arranged in parallel according to the expanded shape of the corona reactor 500.

The branch pipe 411 is connected to the corona reacting unit 500 when the odor and noxious gas and dust that flow into the inlet pipe 410 are directly supplied to the corona reacting unit 500, The amount of dust to be supplied to the corona reacting unit 500 may be varied so that a uniform amount of odor, noxious gas and dust can be supplied to the corona reaction unit 500. For this purpose, the branch pipe 411 is connected to each branch pipe 411 And a flow rate regulator 414 is provided at the other end of the inflow pipe 410, that is, at a branch point of the branch pipe 411 from the inflow pipe 410, The opening amount of the flow rate regulating device 414 can be varied so that the output value of the flow rate sensor 413 in each branch pipe 411 is matched. At this time, the flow rate regulator 414 is shown to have one flow rate regulator 414 installed at the other end of the inlet pipe 410. However, the flow rate regulator 414 may be installed at the inlet of each branch pipe 411, Respectively.

When the flow sensor 413 is provided in each of the branches 411 as described above, only the concentration sensor is provided in the inlet pipe 410 so that the output value of the flow sensor 413 of the branch pipe 411 and the output value of the inlet pipe 410 can be mutually combined to vary the output value of the high voltage applying device 541. [

2 and 3, the corona responding unit 500 firstly removes odor, noxious gas, and dust from the inlet H of the inflow unit 400, A dust collecting part 520 provided at a lower part of the upper housing 510 and a dust collecting part 520 provided at a lower part of the dust collecting part 520 And is disposed in an inner hollow portion formed by coupling the lower housing 530 and the upper housing 510, the dust collecting portion 520 and the lower housing 530 in communication with the inlet portion 400 to discharge corona and harmful gas And a corona discharge part 540 for removing the corona discharge part 540.

2 to 4, the upper housing 510 is connected to the lower end of the catalyst purifying part 600 and is connected to the catalyst purifying part 600 through the exhaust port of the catalytic purifying part 600. The odorous and noxious gas, And a high voltage application device 541 and an upper insulation part 542 of the corona discharge part 540 are provided in the inner hollow part of the upper housing 510. [ The dust collecting unit 520 is connected to the lower end of the upper housing 510 and the malodorous and harmful gas and dust raised from the dust collecting unit 520 are supplied to the upper housing 510 through the high voltage applying unit 541, And is uniformly supplied to the upper catalytic purifier 600 by the eductive part 542 or the like.

2, the dust collecting unit 520 is connected to the lower end of the upper housing 510 and communicates with the upper end of the lower housing 530. The dust collecting unit 520 includes a discharger 543 of the corona discharging unit 540 The odor and noxious gas supplied from the lower housing 530 and the dust are first purified by the discharger 543 of the corona discharge part 540 to be moved to the upper housing 510 .

4, the dust collecting unit 520 includes two bending plates 521 spaced apart from each other and two side plates 522 connecting between both ends of the two bending plates 521, And each bending plate 521 is folded so as to have a folding line in the vertical direction to form a depression 523 having an equal interval inward. At this time, the depressed portions 523 of the two bending plates 521 are formed at the same positions to face each other, and a hollow portion 524 having a regular polygonal shape including the depressed portions 523 is continuous in the interior Respectively.

In more detail, the bent plate 521 is formed by bending a plate-shaped panel. The wedge-shaped depressed portion 523 has a shape formed at regular intervals toward the inside. That is, the starting point at which the depression 523 starts, the tip of the depression 523, and the end point at which the depression 523 ends are the fold lines of the bending plate 521, . Since the bent plate 521 is disposed to face the two bent plates 521 so as to be spaced apart from each other, the starting point, the leading end, and the ending point of the depressed portion 523 of one bent plate 521, When the starting point, the leading end, and the ending point of the depressed portion 523 of one bending plate 521 are formed, they become regular polyhedrons.

The reason for forming the depression 523 is due to the corona generation region formed by the discharge unit 543 of the corona discharge unit 540. The corona formed by the discharge unit 543 is centered on the discharge unit 543 And has a circular generation region. When the folding plate 521 of the dust collecting unit 520 is formed as a flat plate, a plurality of discharge units 543 are arranged in the dust collecting unit 520 at regular intervals. In this case, The reaction zone 10 is generated, and the gas passing through the corona non-reaction zone 10 can not purify odor and harmful gas. Therefore, in order to minimize the corona non-reaction zone 10, the depression 523 is formed in the bent plate 521 so as to surround the corona generation region.

At this time, in order to completely cover the corona generation region, the bent plate 521 must be formed into a cylindrical shape and applied to each of the discharge units 543 separately. In this case, the flow of odor, noxious gas, and dust is not smooth, I will not. Accordingly, the corona generation region can be appropriately covered, and the depression 523 is formed so that the hollow portion 524 surrounding each discharge unit 543 is communicated with each other so as not to interfere with the flow of odor, noxious gas, and dust.

That is, the shape of the hollow portion 524 surrounding the discharger 543 is a regular polygonal shape, and the hollow portion 524 having a regular polygonal shape is formed in order to communicate therewith, and the bent plate 521 is formed to surround the outer side of the hollow portions. And a side plate 522 are provided.

The lower housing 530 includes odor and noxious gas supplied through the inlet portion 400, And the lower hollow portion of the corona discharging portion 540 is provided with the lower insulating portion 544. The lower insulating portion 544 of the corona discharging portion 540 is provided in the inner hollow portion.

The upper housing 510 and the lower housing 530 have a relatively smaller area in plan view than the upper housing 510 and the lower housing 530. In order to install the dust collecting unit 520 in the vertical direction, A plurality of support pillars 545 may be provided.

The corona discharge unit 540 includes a high voltage application unit 541 provided inside the upper housing 510 as shown in FIG 2 and a high voltage application unit 541 connected to the high voltage application unit 541 by being extended downward from the high voltage application unit 541, A plurality of discharge units 543 for performing a corona discharge using a power supplied from the discharge unit 543 and a discharge unit 543 provided in the upper housing 510 and the lower housing 530 to support the upper and lower parts of the discharge unit 543, An upper insulating portion 542 and a lower insulating portion 544 that electrically insulate the upper housing 510, the lower housing 530, and the dust collecting portion 520 from each other.

The high voltage applying device 541 is provided in the inner hollow portion of the upper housing 510 to allow a high voltage to be applied to the discharger 543, and includes a high voltage generating device and a high voltage distributing device. The high voltage generating apparatus generates a voltage according to an output value set on the basis of the output value of the flow sensor 412 or the concentration sensor 413 of the inlet 400. The high voltage distributor has a plurality of the dischargers 543 coupled thereto So that the voltage generated from the high voltage generating device can be evenly distributed to each of the dischargers 543.

The discharger 543 is formed in a bar shape and extends downward from the high voltage distributing device of the high voltage applying device 541 to be disposed at equal intervals in the dust collecting part 520 and supplied from the high voltage applying device 541 The corona discharge is performed using a high voltage. The discharge unit 543 forms a circular corona generation region around the discharge unit 543, whereby odor and noxious gas passing through the dust collecting unit 520 are first purified. The ozone generated by the corona discharge of the discharger 543 is supplied to the catalyst purifying part 600 together with the malodor, noxious gas and dust to become the activation energy source of the catalyst 610 of the catalyst purifying part 600.

The upper end of the discharger 543 is coupled to the upper insulating portion 542 and the lower end thereof is coupled by the lower insulating portion 544 to be electrically insulated from the upper housing 510, the lower housing 530, and the dust collecting portion 520 At this time, the upper end of the discharger 543 may be coupled to the upper insulating part 542 so as to protrude by a predetermined length.
