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

The present invention proposes a device for removing a complex odor by constituting a flow path of a gas. But is not necessarily limited to, a site generating a large amount of complex odors such as a waste disposal site, a sewage disposal site, and a sewage disposal site. Medium and large scale environmental facilities are required to design not only to not exude odor to the outside but also to keep the internal working environment pleasant. Therefore, it is recognized that one of the important design factors is flexibility in which the flow path of the gas to be treated can be variably operated.

According to the present invention, the main body 10 has a structure in which a plurality of the cylinders are relatively displaceable. The main body 10 forms a flow path for deodorizing the gas by using a plurality of cylinders. The cylinder is a functional block modularized to include cleaning means 30, post-processing means 40 and the like, which will be described later. The variation of the relative position of the cylinder in medium and large scale environmental facilities leads to the improvement of treatment efficiency by the flexibility of the flow path.

The main body 10 of the present invention is constituted such that the main tubular body 11 and the sub tubular body 12 are annularly detachably coupled to the main tubular body 11 and the sub- And the positional change of the position of the movable member is permitted. In FIG. 1, two main cylinders 11 and two sub cylinders 12 are annularly coupled on the central cylinder 13 to form one large cylindrical body. An inlet duct (15) and a blower (25) are installed on the outer surface of the adjacent main cylinder (11).

On the other hand, a castor is provided on the bottom surface of the main body 10 to omit the illustration, and the ease of horizontal movement is ensured, and a hanger is provided on the upper surface of the main body 10, In any case, it is possible to improve the efficiency of removal of odor components by facilitating installation and change in an appropriate position in an environment facility of medium and large scale.

According to the present invention, a cleaning means (30) for selectively supplying an alkaline or acidic washing liquid includes a poling (35) and an injector (36) on the main body (10). Fig. 2 illustrates a state in which the poling 35 and the injector 36 are installed inside the main cylinder 11. Fig. Polling 35 employs a structure in which ion exchange fibers are provided as porous bodies to remove odorous components such as hydrogen sulfide. The injector 36 has a plurality of nozzles on the upper side of the poling 35 and injects a predetermined cleaning liquid to promote the removal of odor components. The alkaline cleaning liquid and the acidic cleaning liquid are separately stored and selectively provided as described below.

In the detailed construction of the present invention, the main cylinder 11 connects the first cleaner 31 and the second cleaner 32 to the central cylinder 13 by a parallel flow path, And the flow path is switched by the damper provided in the upstream duct (16) and the downstream duct (17). In Fig. 1, the main tubular body 11 is divided into a first tubular portion 31 and a second tubular portion 32 and is adjacently joined on the central cylindrical body 13. As shown in Fig. The first washing unit 31 is treated with an alkaline washing liquid to remove acidic and neutral odor components, and the second washing unit 32 is treated with an acid washing liquid to remove alkaline odor components. 2, an upstream damper 22 is provided in an upstream duct 16 communicating with the lower side of the main cylinder 11 and a downstream damper 23 is provided in a downstream duct 17 communicating with the upper side of the main cylinder 11 Respectively. The inflow damper 21 installed on the inflow duct 15 opens and closes the first cleaner 31 or the second cleaner 32 in opposite directions. A space is provided between the upstream duct (16) and the downstream duct (17) on the central cylinder (13) for operation of the post-treatment means (40).

At this time, the first cleaning part 31 and the second cleaning part 32 have respective cleaning liquid reservoirs 33 on the upper side. Since the cleaning liquid tank 33 is disposed on the upper side of the main cylinder 11, power consumption for supplying the cleaning liquid can be reduced. Acid odor such as hydrogen sulfide, methyl mercaptan and the like, and neutral odor such as methyl sulfide, dimethyl disulfide, acetaldehyde, and styrene can be used as cleaning liquid of alkali hypochlorite solution. Alkaline odors such as ammonia and trimethylamine can be used as a cleaning solution.

3 shows a flow path by the first cleaner 31 and the second cleaner 32 of the main cylinder 11. As shown in Fig. 3 (a), when the inflow damper 21 moves to the left side, the gas is treated with the alkaline cleaning liquid while the first cleaner 31 is downward, and the upstream duct 16 is connected to the upstream damper 22 via the one- Processing unit 40 after being introduced into the downstream duct 17 through the downstream damper 23 and being treated with the acid washing liquid while the second washing unit 32 is upwardly moved through the other upstream dampers 22, Lt; / RTI > 3 (b) shows the case in which the inflow damper 21 has moved to the right, and the gas is discharged through the second cleaner 32, the first cleaner 31, and the post-treatment means 40 in the opposite manner. Of course, the switching of the flow path by the inflow damper 21, the upstream damper 22 and the downstream damper 23 is executed by the controller 55 of the control means 50 described later.

As a modification of the present invention, the sub-cylinder 12 is configured to be redundantly configured to perform the same function as the main cylinder 11 and to be deployably deployed via at least one hinge 27 . The sub cylinder 12 also has the same first but the first cleaner 31, the second cleaner 32 and the cleaning liquid tank 33 in the same manner as the main cylinder 11 but with a relatively small capacity. The constitution of the inflow damper 21 of the inflow duct 15, the upstream damper 22 and the downstream damper 23 communicating with the central cylinder 13 are also applied. Thus, the sub cylinder 12 can be used temporarily in the maintenance and repair process of the main cylinder 11 in addition to the function of temporarily reducing the processing burden on the main cylinder 11. [ 4 shows a state in which two sub cylinders 12 are connected to the main cylinder 11 by a hinge 27 and developed. And has a highly elastic oil-hydraulic connection (28) for maintaining the flow path at the time of deployment of the sub-cylinder (12). Thus, since the position of the sub cylinder 12 with respect to the main tubular body 11 can be easily changed, the efficiency of the malodor component processing can be improved in accordance with the fluctuation of the surrounding environment.

Further, according to the present invention, the post-treatment means 40 has a structure in which the UV irradiator 43 and the absorber 47 are provided downstream of the cleaning means 30 in the main body 10. In FIG. 2, the post-treatment means 40 is arranged so as to be distributed on the upper and lower sides of the downstream duct 17 on the central cylinder 13. The UV irradiator 43 performs a biological treatment for removing various bacteria by irradiating ultraviolet rays. The damper 47 performs the function of removing the remaining odor component and fine dust based on activated carbon.

As a detailed construction of the present invention, the post-treatment means (40) further comprises an atomizer (41) for spraying water to cope with the physical properties of the complex odor and an ozone sterilizer (45) for supplying ozone gas. The sprayer 41 pumps water into the fine nozzles by pumping water in a space formed below the downstream duct 17. The ozone sterilizer 45 performs a biological treatment for removing various bacteria by adding ozone gas. The sprayer 41 and the ozone sterilizer 45 are advantageously used in combination to reduce the amount of outside air discharged from the ozone gas. However, it is preferable to use this for a limited period of time when dust, bacteria, etc. remaining in the complex odor are increased due to changes in the surrounding environment.

On the other hand, in the disinfection by the UV irradiator 43, oxygen is separated by ultraviolet rays to generate active oxygen (O), active oxygen combines with other oxygen (O ₂ ) to generate ozone (O ₃ ) It reacts with the moisture contained in the odor to generate hydroxide radicals, which sterilize the microorganisms.

Further, according to the present invention, the control means (50) controls the cleaning means (30) and the post-processing means (40) with an established algorithm. The control means 50 includes a gas detector 51 installed to detect the type of the malodor component, a pH detector 53 installed to detect the concentration of the malodor component, a controller 55). The controller 55 includes a microprocessor, a memory, and a microcomputer circuit equipped with an input / output interface. The gas detector 51 and the pH detector 53 are connected to the input interface of the controller 55 and the dampers 21, 22 and 23, the blower 25, the injector 36, the atomizer 41, a UV irradiator 43, an ozone sterilizer 45, and the like.

As an example of the control algorithm, the controller 55 determines the main constituents of the odor with the signals of the gas detector 51 and the pH detector 53 to determine the flow of one of the first cleaner 31 or the second cleaner 32 And finally removes the malodor component through the post-treatment means 40 after the set flow path. If the main component of the odor fluctuates, the sequence of the first and third scissors 31 and 32 may be changed and the subcancellation 12 may be temporarily operated according to the set conditions.

A solution for neutralization of ammonia, trimetalamine and the like, which are representative of alkaline odor, is neutralized with a sulfuric acid solution. In this case, the sulfuric acid solution preferably maintains a pH of 2 or more so as to maintain a removal rate of 90% or more.

5, the main body 10 includes an inlet duct 15 in a lower space of the main cylinder 11, an upper duct (not shown) in the upper space of the main cylinder 11, And an auxiliary duct (29) that forms a flow path with the first duct (16). The inflow duct 15 and the inflow damper 21 for operating it are in the same manner as in Fig. 2 and change the position downward. The auxiliary duct 29 is installed in the central cylinder 13 and connects the upper space of the main cylinder 11 and the upstream duct 16. [ Therefore, the gas flowing into the inlet duct 15 flows in the direction in which it always ascends in the first cleaner section 31 and the second cleaner section 32. It is preferable to add a damper (not shown) to the auxiliary duct 29 to switch the system of Fig. 2 or 5 depending on the composition of the gas.

On the other hand, a collector 39 is provided below the poling 35 in the main cylinder 11 to dispose or recycle the collected water and foreign matter. The circulator 38 is provided at the lower end of the central cylinder 13 and the controller 55 is operated to restore and recycle the cleaning liquid discharged from the first cleaning units 31 and 32.

Referring to FIG. 6, the concentration of hydrogen sulfide, methyl mercaptan, ammonia, and trimethylamine is decreased by the apparatus of the present invention. For example, it can be seen that the concentration of hydrogen sulfide is inhaled at 20 to 36 PPM in the inlet duct 15 and reduced to 0 to 0.05 PPM at the outlet.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
