In particular, the organic matter contained in sewage and wastewater is unstable and is liable to be decayed, odorous upon decay, and may be deteriorated to harmful substances to the human body and ecosystem, which may cause hygiene problems.

Moreover, in the case of hot summer, when the sewage pipe is opened due to an increase in the amount of generated gas as described above, a bad odor is generated, thereby causing complaints around the user. In particular, hydrogen sulfide generated by the decay of wastewater generates sulfuric acid due to the occurrence of sulfur bacteria, which causes erosion of cement and corrosion of the wells.

Various deodorizing devices have been developed to remove odors generated in sewage and wastewater. The deodorization apparatus may be a physicochemical treatment method such as an activated carbon adsorption method, an ozone oxidation method, a combustion deodorization method, or a biological method such as a soil microorganism treatment method, an activated sludge method, or a biofilter.

The disclosed conventional deodorizing apparatus ejects a liquid catalyst to the outside air containing odor components to remove sulfur compounds.

In the conventional deodorizing apparatus as disclosed, deodorization proceeds by continuously spraying the corresponding remover or liquid catalyst to remove the acidic odor or alkali odor component. Therefore, there is a problem that the amount of wastewater used for the removal is large and the cost for treating the waste water increases.

Further, since the pump must be driven to continuously spray the liquid catalyst, the management cost is also high. Further, since the injection amount of the liquid catalyst per hour is determined, there is a limit in that the amount of the processing gas can not actively respond to the increase.

For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist of the present invention are omitted.

1 is a schematic view schematically showing a configuration of a malodor removing system 1 according to the present invention. As shown in the drawing, the malodor removing system 1 according to the present invention includes a desulfurizer 100 for removing sulfur compounds of malodorous gas G1 containing odors, a primary treatment gas And a cation exchange fiber unit 200 for removing the alkaline odor contained in the G2.

The desulfurization apparatus 100 removes sulfide gas contained in the malodorous gas G1 using a desulfurizing agent and the cation exchange fiber unit 200 uses the cation exchange fiber 221 to remove the sulfide gas contained in the primary treatment gas G2 Remove alkaline odors such as ammonia.

2 is a schematic view showing the construction of a dry desulfurization apparatus 100 according to the present invention. As shown in the drawing, the desulfurization apparatus 100 according to the present invention includes a desulfurization agent A, which is filled with sulfur gas contained in a malodorous gas G1 flowing from a lower portion thereof, .

The dry desulfurization apparatus 100 according to the present invention comprises a reaction tank 110 filled with a desulfurizing agent A and a malodor gas guiding unit 110 connected to a lower portion of the reaction tank 110 to feed the malodor gas G1 into the reaction tank 110. [ And a double strainer 130 disposed at a lower portion of the reaction tank 110 for uniformly distributing and supplying the malodorous gas G1.

The reaction tank (110) forms a space filled with the desulfurizing agent (A). A desulfurizing agent inlet 111 for introducing the desulfurizing agent A and a processing gas outlet 113 for discharging the processing gas G2 from which the sulfur compound is removed are provided at an upper portion of the reaction tank 110. A drain port 115 is provided in the lower part of the reaction tank 110. The drain port 115 discharges reaction water W generated when the desulfurizing agent A and the malodorous gas G1 are desulfurized.

3 is a projection perspective view showing a lower structure of the dry desulfurization apparatus 100. As shown in FIG. As shown in the figure, the malodor gas guide unit 120 is coupled to the bottom surface of the reaction tank 110. The malodor gas guide unit 120 guides the malodorous gas G1 so that the reaction water W accumulated on the bottom surface of the reaction tank 110 and the malodorous gas G1 are not brought into contact with each other but supplied to the desulfurizer A side.

The malodor gas guide unit 120 includes a malodor gas guide pipe 121 inserted into the bottom surface for a predetermined length of time, a cutoff cover 123 arranged to be spaced apart from the malodor gas guide pipe 121, And a support leg 125 connecting the upper portion of the gas guide tube 121.

The malodor gas guide pipe 121 is provided in a tubular shape having a predetermined length and is inserted into the inside of the reaction tank 110 through the lower part of the reaction tank 110. At this time, the length of the odor gas guide pipe 121 is set so that the length inserted into the reaction tank 110 exceeds the maximum receiving depth of the reaction water W accumulated on the bottom surface of the reaction tank 110. As a result, the odor gas G1 discharged to the upper portion of the odor gas guide pipe 121 does not come into contact with the reactive water W.

The blocking cover 123 is connected to the upper end of the malodor gas guide pipe 121 opened at the upper part so that the reaction water W generated by the desulfurizing reaction between the desulfurizing agent A and the malodor gas G1 in the reaction tank 110 So that it is prevented from flowing into the malodor gas guide pipe 121. Thus, the contact of the malodor gas G1 with the reaction water W is prevented before the sulfur gas G1 comes into contact with the desulfurizing agent A, so that the desulfurization reaction can proceed smoothly.

At this time, the malodor gas guide pipe 121 and the blocking cover 123 are joined by the supporting leg 125. A plurality of support legs 125 extend upwardly at regular intervals along the upper outer periphery of the malodor gas guide pipe 121 to be engaged with the shutoff cover 123. An odor gas discharge hole 127 is formed at a distance between the plurality of support legs 125 so that the odor gas G1 moved through the odor gas guide pipe 121 flows into the reaction tank 110.

The double strainer 130 is coupled to the lower portion of the reaction tank 110 so that the malodor gas G1 discharged from the malodor gas guide unit 120 is uniformly distributed and supplied to the desulfurizer A. The double strainer 130 is provided with a lower strainer 131 and an upper strainer 133 arranged in the transverse direction in the reaction tank 110.

4 is an exploded perspective view showing the structure of the double strainer 130 in an exploded manner. As shown in the drawing, the lower strainer 131 and the upper strainer 133 are arranged in the transverse direction in the reaction tank 110 at a predetermined interval. The lower strainer 131 and the upper strainer 133 are provided on the moving path of the malodor gas G1 discharged from the malodor gas guide unit 120 so as to correspond to the area of the reaction tank 110. [

The lower strainer 131 and the upper strainer 133 are provided with a metal plate. The lower strainer 131 is provided with a plurality of lower slits 131a at regular intervals on the plate surface thereof and the upper strainer 133 is provided with a plurality of upper moving holes 133a at regular intervals.

The lower slit 131a is provided in the form of an elliptical long hole having a predetermined length l and the upper moving hole 133a is provided in a circular shape having a constant diameter r. At this time, the length 11 of the lower slit 131a is formed to correspond to the arrangement interval of 2 to 3 upper moving holes 133a.

Here, the plurality of lower slits 131a and the plurality of upper moving holes 133a are alternately arranged so as not to be arranged coaxially with each other.

The malodor gas G1 divided and supplied to the plurality of lower slits 131a is scattered and supplied to the upper moving hole 133a after being struck against the wall surface of the upper strainer 133, So that they are uniformly distributed and supplied to all the regions. Therefore, the malodorous gas G1 can be evenly contacted with the desulfurizing agent in the entire region of the reaction tank 110. Since the desulfurization reaction occurs uniformly, the efficiency of removing the sulfur compounds increases, and the reaction rate can also be increased.

In the meantime, the dry desulfurization apparatus 100 according to the present invention may include a drain port 140 for draining the reaction water W accumulated in the lower portion of the reaction tank 110 to the outside. The drainage opening portion 140 allows the reactant water W to be automatically discharged to the outside according to the water level received in the reaction tank 110 even if the manager does not discharge the reactive water W manually.

Meanwhile, the desulfurizing agent (A) to be filled in the reaction tank (110) of the present invention may be prepared by mixing glass powder (or waste glass) with fly ash, intercrition, water glass and iron oxide (Fe ₂ O ₃ ) . Here, waste glass (or glass powder), fly ash, intercrit, and water glass are ceramic compositions used as insulation materials for building materials. The glass powder can be applied not only to general glass powder but also to waste glass powder.

The ceramic composition contains many pores therein and thus has a light weight and a large specific surface area. The desulfurizing agent (A) of the present invention is prepared by adding iron oxide (Fe 2 O 3) to the ceramic composition in order to increase desulfurization removal efficiency.

The reaction tank 110 of the present invention may be filled with a desulfurizing agent as well as a conventional desulfurizing agent.

The desulfurizing agent of the present invention thus produced can be used as a very good filter medium formed of a large number of pores formed during sintering. Particularly, the added iron oxide (Fe ₂ O ₃ ) can be used as an adsorbent such as hydrogen sulfide or mercaptan The sulfur compounds can be removed via a reaction mechanism.

Among the malodorous components of the odorous gas, the hydrogenated hydrogen reacts as follows.

Fe ₂ O ₃ 3H ₂ O + 3H ₂ S --------> Fe ₂ S ₃ + 6H ₂ O

Fe ₂ O ₃ 3H ₂ O + 3H ₂ S --------> 2FeS + S + 6H ₂ O

5 is a schematic view showing the configuration of the cation-exchange fiber portion 200 of the present invention. The cation exchange fiber unit 200 removes the alkaline odor component of the primary treatment gas G2 from which sulfur compounds have been removed in the desulfurizer 100.

The cation exchange fiber unit 200 includes a casing 210 in which the alkaline odor is removed, a cartridge 220 detachably coupled to the inside of the casing 210 and having cation exchange fibers 221 bonded to the plate surface, A regeneration liquid tank 230 provided at a lower portion of the cation exchange fiber unit 210 and containing the regeneration liquid R for regenerating the cation exchange fiber 221, And a liquid supply pipe 240.

The casing 210 is formed in a closed enclosure shape and has an inlet 211 through which the primary processing gas G2 flows in the front and a secondary processing gas G3 in the direction opposite to the inlet 211. [ The discharge port 213 is opened.

The cartridge 220 is detachably coupled to the casing 210. Although the attachment / detachment structure of the casing 210 and the cartridge 220 is not shown in the drawings, the guide rails and the engagement grooves may be provided so as to be in sliding engagement with each other. The cartridge 220 is formed of a plate-like material having a predetermined thickness, and a plurality of cation exchange fibers 221 are freely coupled to the plate surface.

The cation exchange fiber 221 is formed by coating a cation exchange resin on the fiber surface. The cation exchange fibers 221 may be made of one or more fibers selected from the group consisting of polyester, nylon, polyethylene, polypropylene, polyisopropylene, polybutylene, and acrylic, which are excellent in elasticity, resilience and strength.

The cation exchange fibers 221 are adhered to the surface of the cartridge 220 at one end, and the other end is provided at a free end. The cation exchange fiber 221 is adhered to the surface of the cartridge 220 by an adhesive or a hot melt adhesive.

Cation exchange resins have cations that easily fall off to a negatively charged fixed ion. As the cation exchange resin, "R-SO ₃ H" which is a strongly acidic cation exchange resin and "R-COOH" which is a weakly acidic cation exchange resin may be used.

FIG. 6 is an exemplary view schematically showing a process in which the alkaline odor is removed through the cation exchange fiber portion 200.

As shown in the figure, the cation exchange fibers 221 are bonded to the cartridge 220 in a direction in which a plurality of the cation exchange fibers 221 are mutually free. The plurality of cartridges 220 are arranged at a certain distance from each other and the primary processing gas G2 is moved to a space between the adjacent cartridges 220. [

At this time, the other end of the plurality of cation exchange fibers 221 is formed so as to protrude into the space between the cartridges 220, and the primary treatment gas G2 is moved in contact with the cation exchange fibers 221. The primary treatment gas G2 is brought into contact with the cation exchange fiber 221 and the alkaline odor contained in the primary treatment gas G2 can be removed.

The length l of the cation exchange fiber 221 is set to be 1/3 to 1/2 of the width of the space between the cartridges 220 to maximize the contact area with the primary processing gas G2 . For example, when the width of the space between the cartridges 220 is 1 cm, the length of the cation exchange fibers 221 may be 0.5 cm.

Since a plurality of the cation exchange fibers 221 having such a small thickness are coupled to the surface of the cartridge 220 and are disposed on the movement path of the primary processing gas G2, the high contact area due to the filter structure using the fiber yarn causes the alkaline It is possible to increase the efficiency of removing odor.

In addition, since the primary process gas G2 is moved through the gap between the cartridges 220, pressure drop during movement inside the casing 210 can be minimized.

Here, the low concentration odor generated in the wastewater treatment plant varies greatly with time, season, and concentration. In this case, the cation exchange fiber portion 200 of the present invention can actively cope with the low concentration odor amount by adding or subtracting the number of cartridges 220 coupled to the casing 210.

The regeneration liquid tank 230 is provided at a lower portion of the casing 210 to receive the regeneration liquid for regenerating the cation exchange fibers 221. The cation exchange resin adhered to the cation exchange fiber 221 is saturated by the exchange of the cation with the primary treatment gas G2. When the cation exchange fiber 221 is saturated, the cation exchange can not be performed any more, and the alkaline odor can not be removed. Therefore, it is necessary to supply the regeneration liquid so that the cation exchange resin can be regenerated.

The regeneration liquid stored in the regeneration liquid tank 230 may be made of sulfuric acid. The regeneration liquid tank 230 is connected to the regeneration liquid supply pipe 240. The regeneration liquid supply pipe 240 extends to the upper portion of the cartridge 220 and discharges the regeneration liquid R downward from the upper portion of the cartridge 220. [ A plurality of regeneration liquid supply nozzles 241 for injecting the regeneration liquid R into the cartridge 220 may be provided in the regeneration liquid supply pipe 240.

A supply pump 231 for supplying the regeneration liquid R to the regeneration liquid supply pipe 240 is provided at one side of the regeneration liquid tank 230 and a regeneration liquid supply pipe 240 for regeneration of the supply of the regeneration liquid R to the regeneration liquid supply pipe 240 A liquid supply valve 250 is provided.

The cation exchange fiber unit 200 according to the present invention does not supply water separately except the regeneration liquid tank 230 periodically supplies the regeneration liquid R to regenerate the cation exchange fiber 221, The amount of wastewater to be treated can be significantly reduced compared to the conventional scrubber system. Further, since the supply pump for supplying the regenerant R is also periodically driven, the power consumption for removing the malodor can be reduced.

Therefore, the overall management cost for removing odors can be reduced.

On the other hand, the anion-exchange fiber portion 300 is connected to the rear end of the cation-exchange fiber portion 200 and passes through the cation-exchange fiber portion 200 to remove the acidic odor contained in the secondary treatment gas G3 from which the alkaline odor has been removed It can be additionally removed.

The anion exchange fiber portion 300 has the same structure as the cation exchange fiber portion 200, but the anion exchange fiber is bonded to the surface of the cartridge 220. Anion exchange resin adheres to the surface of the anion exchange resin. As the anion exchange resin, "CH ₂ N (CH ₃ ) ₃ CL" which is a strongly basic anion exchange resin and "CH ₂ N (CH ₃ ) ₂ " which is a weakly basic anion exchange resin can be used.

On the other hand, sodium hydroxide may be used as the regeneration liquid for the anion exchange fiber portion 300.

The first treatment gas is passed through the cation exchange fiber unit 200 and the anion exchange fiber unit 300 of the present invention and the SOx, NOx, HCL, HF, HNO ₃ , H ₂ SO ₄ , NH ₃ , Acid odors such as amines, dioctyl phthalate, dibutyl phthalate, boron, siloxane, phosphate, and phosphorus, and alkaline odors and volatile organic compound gases can be adsorbed and removed.

Meanwhile, although the malodor removing system of the present invention includes the cation exchange fiber portion and the anion exchange fiber portion separately, the cation exchange fiber and the anion exchange fiber may be provided together in one cartridge, as the case may be. In this case, the alkaline odor and the acid odor can be removed together via the cartridge.

The operation of the malodor removing system 1 according to the present invention having such a configuration will be described with reference to Figs. 1 to 9. Fig.

The odor gas G1 generated in the wastewater treatment plant is discharged to the outside via the desulfurizer 100, the cation-exchange fiber unit 200, and the anion-exchange fiber unit 300. [ At this time, the anion-exchange fiber portion 300 can be selectively bonded.

First, as shown in FIGS. 2 and 3, the malodor gas G1 is moved into the reaction tank 110 along the malodor gas guide pipe 121 as shown in FIG. The odor gas G1 is moved to the side of the odor gas guide pipe 121 along the exhaust hole 127 formed between the support legs 125 by the length of the odor gas guide pipe 121. [

The malodorous gas G1 flowing into the reaction tank 110 moves upward and passes through the double strainer 130. 4, the malodor gas G1, which is moved via the lower slit 131a of the lower strainer 131, is contacted with the plate surface of the upper strainer 133 and is dispersed and moved to the upper moving hole 133a . The malodor gas G1 moved along the plurality of upper moving holes 133a is uniformly in contact with the entire area of the desulfurizing agent A and the reaction tank 110, and the desulfurization reaction proceeds.

It reacts with the desulfurizing agent (A) mixed with ferric oxide (Fe ₂ O ₃ ), glass powder (or waste glass), fly ash, intercritter and water glass to remove sulfur compounds at a high rate.

The reaction water W generated in the desulfurization reaction falls down to the lower portion of the reaction tank 110. At this time, the reaction water W is blocked by the blocking cover 123 from entering the odor gas guide pipe 121. Then, when the water level of the reaction water W rises to the maximum value with the lapse of time, the reaction water W is discharged to the outside.

The primary treatment gas G2 from which the sulfur compound has been removed moves to the upper portion and then to the cation exchange fiber portion 200 through the process gas outlet 113. [

The primary process gas G2 is transferred into the casing 210 through the inlet 211. [ In the casing 210, a plurality of cartridges 220 are spaced apart from each other at regular intervals. The primary processing gas G2 is moved to a space between the plurality of cartridges 220 as shown in Fig. 9 and is contacted with a plurality of cation exchange fibers 221 protruding from the surface of the cartridge 220. [

The alkaline odor including the ammonia contained in the primary treatment gas (G2) is removed by the ion exchange process. The secondary process gas (G3) from which the alkaline odor has been removed is discharged to the outside through the discharge port (213). In some cases, the secondary treatment gas G3 enters the anion exchange fiber unit 300 and the acidic odor is removed by the same process.

As described above, in the malodor removal system according to the present invention, the dry desulfurization apparatus forms a path so that the malodor gas moves in a zigzag form in the lower strainer and the upper strainer, which are arranged vertically without using gravel, . As a result, the contact area between the desulfurizing agent and the malodorous gas is widened so that the desulfurization reaction proceeds smoothly.

In addition, the cation exchange fiber portion and the anion exchange fiber portion can be used to remove the odor without any additional power by using the ion exchange structure of the fiber yarn. In particular, since a large number of thin fiber yarns are in contact with the odor, the contact area is widened and the odor removing efficiency can be increased.

Further, since the primary process gas is moved to the space between the cartridges, the pressure loss inside the casing is small.

In addition, since there is no use of water other than the regenerated water, the waste water treatment cost and the management cost due to the power consumption can be reduced compared to the conventional method.

Further, since the cartridge can be detachably coupled to the casing, the processing capacity can be actively increased or decreased in accordance with the throughput of the malodor.

The embodiments of the malodor processing system of the present invention described above are merely illustrative and those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. It will be possible. Therefore, it is to be understood that the present invention is not limited to the above-described embodiments.
