[0001] Continuous processing type deodorization system [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorization system, and more particularly, to a deodorization system of a continuous treatment type that enables continuous and high-efficiency processing of odor and VOC (Volatile Organic Compounds).

Generally, as the industry develops, industrial wastes are generated as a by-product, and the population of the city is concentrated, and the generation of municipal waste is also increasing.

These wastes are discharged from waste materials and livestock farms that are discharged from various industrial facilities such as factories such as semiconductor manufacturing, food processing, and papermaking. And the like. These wastes not only contain moisture but also cause odor and VOC (Volatile Organic Compounds) (hereinafter referred to as "stench").

Therefore, the treatment of these odors plays a very important role in the environment, and various deodorization systems have been developed and applied for this purpose.

The microwave generating units 160 and 170 are disposed at the sides of the deodorizing units 110 and 120 so as to output microwaves for reproducing the zeolites 111 and 121 filled in the deodorizing units 110 and 120 to the inside of the deodorizing units 110 and 120, So that it can be installed in the deodorizers 110 and 120, that is, the side where the odor-containing gas is discharged from the chamber, so that the high-concentration odor removal, which is sucked and discharged from the deodorizers 110 and 120, . The microwave generating units 160 and 170 may be formed of a magnetron, for example.

The second opening and closing portions 180 and 190 are installed to open and close the flow of the outside air sucked into each of the deodorizing portions 110 and 120. For example, the second opening and closing portions 180 and 190 are provided to provide a suction and supply passage for the outside air to the front end of the deodorizing portions 110 and 120 Respectively, on the intake lines 181 and 191, respectively.

At this time, while the first opening and closing part 150 allows the supply of odor-containing gas to the deodorizing part 110, which is unnecessary to be regenerated, the deodorizing part 110, And the gas passing through the deodorization unit 110, which is not required to be regenerated by the operation of the third opening and closing unit 220, is prevented from being supplied to the second transfer line 210.

On the other hand, in the case of the deodorization unit 120 requiring the regeneration of the zeolite 121 by the continuous deodorization process in the deodorization units 110 and 120, the operation of the first opening and closing unit 150 causes the large- The second opening and closing unit 190 is opened and closed so that the outside air is supplied to the deodorizing unit 120 that needs to be regenerated and the deodorizing unit 120, The gas sucked from the deodorizing unit 120 is discharged through the plasma processing unit 240 through the second transfer line 210 without being directly discharged to the outside, The gas is deodorized in the plasma processing unit 240 (the "B" path)

On the other hand, as shown in FIG. 3, the deodorization process (the "C" path) for deodorization of the low concentration odor gas with respect to the deodorization units 110 and 120 and the deodorization process, ie, the regeneration process The "D" path) can be performed opposite to that of FIG.

The above-described operations may be performed by controlling the controller 250 to perform the regeneration of the zeolite 111, 121 with respect to each of the deodorizers 110, 120 for the determined order and the predetermined time.

As described above, according to the present invention, a plurality of deodorized parts are deodorized and a regeneration process is performed on a part of the deodorized parts, so that a continuous deodorization process can be performed, excellent deodorization efficiency can be maintained, And it is possible to increase the energy efficiency and the odor treatment efficiency by intensive plasma treatment for the high concentration odor while enabling the large capacity treatment of the low concentration odor.

Although the present invention has been described with reference to the accompanying drawings, it is to be understood that various changes and modifications may be made without departing from the spirit of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
