Description

A system for exhaust gas

The present invention relates to a malodor removing system which is generated in an environmental basic facility such as a sewage treatment plant and which is capable of preventing the malodorous gas from flowing out from a malodor generating source and capable of using a biotrickling filter and an activated carbon adsorption tower together It is possible to improve the odor removing efficiency and the operation efficiency by using the bio-tricling filter. In the case of the bio-tricling filter, it is possible to constitute a multi-layer deodorizing layer to sufficiently dissolve hydrogen sulfide or the like in the malodorous gas and then to remove dissolved hydrogen sulfide. The present invention also relates to a malodor removal system capable of removing various odor reducing substances by removing volatile organic compounds and the like when constituting the upper deodorization layer.

Due to continuous economic development and industrialization, the emission of pollutants is continuously increasing, and the kinds of these pollutants are also diversifying. Particularly, odorous gases generated from manure treatment plants, wastewater treatment plants and various factories include hydrogen sulfide (H ₂ S), mercaptan (R-SH), ammonia (NH ₃ ), amines (RNH ₂ ), volatile organic compounds And these odor gases usually cause headaches or discomfort when the human body is inhaled.

Therefore, studies are being conducted to remove odorous gas in various directions, and accordingly, a lot of odor treatment techniques are known. The currently used odor gas treatment technologies are largely divided into physical treatment methods, chemical treatment methods and biological treatment methods.

The activated carbon adsorption method is known as a physical treatment method. This activated carbon adsorption method is a method of deodorizing by using micro pores of an adsorbent (activated carbon, zeolite, etc.), but there is a problem in that operation and maintenance cost is high due to short replacement period of activated carbon .

As a chemical treatment method, there is known a chemical solution cleaning method using a chemical or liquid catalyst. This chemical solution cleaning method is a method of deodorizing by using neutralization and oxidation reaction of a chemical solution, but also a secondary treatment of wastewater is additionally required. There is a problem that the operation cost is high due to continuous replenishment, and care is required in the handling of medicines.

The biological treatment methods are known as soil deodorization method, aeration tank microorganism deodorization method, and biofilter method. The soil deodorization method is a method in which odorous gas is adsorbed to the soil or oxidized and decomposed by microorganisms existing in the soil. However, it is necessary to cultivate the soil microorganism management and the installation area is large, There are many problems.

The aeration tank microbial deodorization method is a method of oxidizing and decomposing odorous substances by the microorganisms in the aeration tank, but there is a problem that the treatment efficiency varies depending on the operation state of the aeration tank.

In addition, the biofilter method is a biological deodorization method in which microorganisms use a property of using a pesticidal component as a metabolite, but it has a problem of high initial investment cost and regular replacement of the filler media.

On the other hand, Korean Patent Registration No. 10-1063801 (entitled " deodorization device using a rare earth ball carrier ") mentioned in the following prior art documents relates to a deodorizing device for decomposing odor gas by filling a carrier inhabited with microorganisms As a technology, its configuration is as described below.

As shown in FIG. 1, the deodorizing apparatus 10 includes a storage tank 20 filled with water to maintain an appropriate humidity, a carrier (not shown) installed on the upper side of the storage tank 20, And a dispenser for promoting the growth of microorganisms and the maintenance of humidity, dust and water-soluble gas by spraying the water in the storage tank 20 into the deodorization tank 30 by injecting water from the deodorization tank 30 into the deodorization tank 30 40 and a separator 50 for removing the moisture of the treated gas.

In the deodorizing tank 30, the carrier 31 is located at the upper and lower parts of the zone, and the sprayer 41 of the distribution unit 40 is mounted on the upper part of the carrier 31, As shown in Fig. The rare-earth balls constituting the support 31 are uniformly formed in the entirety of the rare-earth balls so that the through-holes 33 are excellent in air permeability.

However, in the case of the carrier including the rare earth ball having the above-described structure, there are the following problems. The rare-earth ball formed with the through-holes as a whole has excellent air permeability, but the water sprayed from the upper part is discharged without being stored in the rare-earth ball, thereby making it difficult to maintain the humidity inside the deodorizing tank.

Since the microorganisms are difficult to habitat and the ventilation is good and the odor gas easily passes through the rare earth ball, the height of the stack of the rare earth balls must be increased, so that the height of the deodorizing apparatus is also increased. There are disadvantages. In addition, rare-earth balls have limitations in removing various odor generating substances such as hydrogen sulfide (H ₂ S), volatile organic compounds, mercaptans (R-SH), and ammonia (NH ₃ ).

The deodorization apparatus 100 does not provide a solution to the problem that the efficiency of the entire system is deteriorated when the odor gas is leaked from the odor source even though the efficiency of removing the odor gas by the deodorizer is high .

2, the malodor removing system of the present invention prevents the malodorous gas from flowing out from the malodor generating source P to the outside by the sealing and collecting means S constituted in the malodor generating source P, And the collected odor gas is put on the deodorizing device and the first deodorizing device 100 and the second deodorizing device 200 are combined or selected to efficiently operate according to the on-site driving conditions such as concentration, maintenance, So that the deodorization efficiency can be improved.

The sealing and collecting means S constituting the malodor generating source P is constituted in the malodor generating source P and is provided with a sealing portion for preventing the malodorous gas from flowing out to the outside, And a collecting part for collecting the odor gas and flowing the odor gas collected by the gas inflow line to be described below.

According to this configuration, the sealing and collecting means S prevents the mixing of the odor-free gas discharged from the first and second deodorizing devices 100 and 200 and the malodor generating source P, Thereby preventing the malodor gas removal efficiency of the system from being lowered. That is to say, it is mixed with the gas deodorized from the first and second deodorizers 100 and 200 by the external leakage of the odor gas from the odor source P, thereby preventing the deodorization efficiency of the malodor gas from being lowered to the entire system.

3A and 3B show an example of use of the malodor removal system of the present invention according to the example of the malodor source P. [

(S-1) refers to a food processing facility, a manure processing facility, a clogging processing facility, a sewage treatment facility And high-concentration odor generating machinery such as sludge treatment facilities.

In this embodiment, the sealing and collecting means S constitutes a sealing portion S-1 which hermetically seals the entire periphery of the mechanical equipment P-1, so that the malodorous gas flows out from the mechanical equipment P-1 ≪ / RTI > In addition, after the collection by the collection unit S-2, the malodor gas collected through the gas inflow line 300 to be described below flows without flowing out to the outside.

Here, the sealing portion (S-1) is made to be able to be hermetically sealed throughout the machine (P-1), and its material is not limited. The collecting part S-2 collects the odor gas sealed by the sealing part S-1 and flows into the gas inflow line 300. The details of the collecting part S-2 are not shown in the drawing A hood for collecting the odor gas and a duct for flowing the collected gas, and the impeller can be constituted as a power source for such collection and flow.

2 shows an open type water tank P-2 and the like. In this case, the open water tank P-2 is an odor generating source, And a facility with an open top.

In this embodiment, the sealing and collecting means S comprises a sealing portion S-3 for sealing the opened upper portion of the water tray P-2 so that the odorous gas flows out from the water tray P- prevent. Further, after the gas is collected by the collecting part S-4 formed on the upper part of the sealed part S-3, the odorous gas collected through the gas inflow line 300 flows without flowing out to the outside.

The sealing portion S-3 covers the upper portion of the water tank P-2 and is not limited to the material. Preferably, the sealing portion S-3 uses relatively light materials such as FRP, aluminum, synthetic resin (PVC, PE, polycarbonate) It is appropriate to give structural stability to the lower water tank P-2.

It is preferable that the sealing portion S-3 is formed by assembling the round unit 10 as shown in FIG. 3B so that the entire sealing portion S-3 is formed in a wavy shape. More specifically, the sealing unit S-3 is formed by assembling a plurality of round units 10 by the bolt coupling 11. As the sealing unit S-3 is formed in a wavy shape, Also in the case of the open water tank P-2 having a large width, rigidity is reinforced due to the shape of the round unit 10, so that the entire sealing portion S-3 can be realized at a low height, A separate supporting structure is not required, and a rigid structure is provided even against external resistance such as wind.

In the case of the collecting part S-4, the malodor gas sealed by the sealing part S-3 is collected and flows to the gas inflow line 300, But it can be composed of a hood for collecting odor gas and a duct for flowing the collected gas, and the impeller can be constituted as a power source for such collecting and flow.

The malodor gas generated from the malodor generation source P flows into the first deodorization device 100 and / or the second deodorization device 200 without being leaked to the outside by the sealing and collecting means S, As shown in FIG. 2, the connection between the first deodorizing device 100 and the second deodorizing device 200 is controlled by the odor source P (the sealing and collecting means S) and the gas inflow line 300 1 deodorization apparatus 100 is connected to the first deodorization apparatus 100 and the second deodorization apparatus 200 are connected by a connection line 400 and at one side of the second deodorization apparatus 200, 500 are connected.

In other words, odorous gas from various odor generating sources P such as a mechanical equipment and a water tank is introduced into the first deodorizing device 100 by way of the gas inflow line 300 and is first biologically deodorized by the first deodorizing device 100 The gas introduced into the second deodorizer 200 is secondarily deodorized by the adsorption of the gas through the connection line 400 to the second deodorizer 200. The first deodorizing device 100 and the second deodorizing device 200 are required to deodorize the high concentration odor gas and the high treating efficiency.

However, in the present invention, no reference numerals are shown by the bypass line 600 during the maintenance of the concentration and characteristics of malodorous gas, particularly the malfunction of the first deodorizing device 100 or the second deodorizing device 200 It is possible to selectively operate the first deodorizing device 100 or the second deodorizing device 200 by opening or closing the corresponding valve. That is, continuous operation is possible without stopping the entire system.

4, the first deodorizing unit A and the second deodorizing unit B are configured by using two or more of the first deodorizing unit 100 and the second deodorizing unit 200 in parallel, respectively, Even if any one of the first deodorizing device 100 or the second deodorant device 200 fails in the first deodorizing part A or the second deodorizing part B, ) Or the second deodorization unit (B) without stopping the operation of the second deodorization unit (B). Of course, this configuration can further improve the deodorization efficiency.

The connection line 400 is provided with a heater unit 700. The heater unit 700 is configured to pass the heater unit 700 through the second deodorizer 200, The second deodorizing device 200 can improve the adsorption efficiency of the activated carbon layer by lowering the moisture content of the gas.

5a, the first deodorizing apparatus 100 includes a deodorizing tank 110 having a countercurrent structure and a deodorizing tank 110 having a deodorizing tank 110 for introducing odorous gas into a lower end of the deodorization tank 110. [ A deodorization layer 120 in which a dissolved media layer 121 and a disassembled media layer 122 are alternately stacked in the deodorization tank 110 and a deodorization layer 120 formed on an upper portion of the deodorization layer 120, A separator 150 disposed at an upper portion of the sprayer 140 to remove moisture of the gas flowing upward and a water supply pipe 140 connected to the deodorization tank 110, And a discharge port 113 formed at the upper end for discharging the odor-free gas.

Preferably, the water collecting tank 101 is located below the first deodorizing apparatus 100, and the water stored in the water collecting tank 101 is sprayed through the sprayer 140 and sprayed to lower the deodorizing layer 120 The circulation line 160 is configured to allow the water stored in the water collecting tank 101 to be re-sprayed. The circulation line 160 is connected to the catch tank 101 and the sprayer 140 to provide moisture necessary for maintaining humidity inside the deodorization tank 110 and for growing microorganisms.

The deodorization tank 110 has a vertical counterflow tower structure. The deodorization tank 110 includes a deodorization tank 110 and a deodorization tank 110. The deodorization tank 110 includes a deodorization tank 110, And passes through layer 120. The deodorization layer 120 is a multilayer structure in which a decomposition media layer 122 in which a decomposition media layer 122 filled with a dissolved mediator layer 121 filled with a dissolved media 131 is alternately stacked.

It is appropriate that the dissolved medium 131 has a spherical structure having a plurality of flow paths and has superior air permeability. The dissolved media 131 is preferably made of a synthetic resin material so as to have excellent water resistance and rigidity.

The dissolved medicament 131 functions to promote the liquefaction of the malodor gas due to the supply of water sprayed from the upper part and the malodorous gas. As described above, when the malodorous gas is received in the replenishing water and liquefied, it becomes easy to decompose the malodor material containing the microorganisms in the decomposition media 132.

Particularly, the deodorization layer 120 is effective for decomposing a water-soluble odor generating substance such as hydrogen sulfide by forming a multi-layer structure and liquefying and decomposing.

In the present invention, as shown in FIGS. 6A and 6B, two embodiments of the dissolved media 131 are shown.

First, the dissolved media 131a shown in FIG. 6A is a spherical structure having a plurality of circular plates 131a-1 and a plurality of circular channels 131a-1, The diameter of the unidirectional disc 131a-1 of the first disc 131a-1 and the disc 131a-2 of the second disc 131a-2 is larger than the diameter of the disc disc 131a-2.

The dissolved media 131a having such a structure are adjacent and laminated between the dissolved media 131a, so that the flow path 131a-4 is formed in multiple directions, and a vortex is generated in the replenishing water passing therethrough. As the vortex is generated in the replenishing water passing between the dissolved media 131a through the respective flow paths 131a-4, the dissolution rate in the replenishing water of the odorous gas is increased.

In addition, in the dissolved media 131a of the present embodiment, the rim 131a-3 protrudes in one direction, so that the dissolved medias 131a are contacted by the rim 131a-3, The supply water and the malodor gas are formed not only by the flow path 131a-4 inside the dissolved media 131a but also by the rim 131a-3 contacting the outside of the dissolved media 131a And flows through the flow path while forming a vortex.

By forming the rim 131a-3 in the dissolved media 131a, it is possible to obtain the same effect by the rim 131a-3 even if the entire diameter is not largely increased. The dissolved media 131a filled by the rim 131a- It is economical in terms of material, and it is advantageous in that the total load can be reduced.

On the other hand, the dissolved media 131b of another embodiment is shown in FIG. 6 (b). In the dissolved media 131b of this embodiment, a plurality of discs 131b-1, A flow path 131b-3 having a plurality of bends is formed.

In other words, as the curved portions of the intersecting discs 131b-1 and 132b are formed, curvature is also formed in the flow path 131b-3 formed by intersection. The dissolved media 131b having such a structure is formed so that the dissolved media 131b are adjacent and laminated so that the flow paths 131b-3 are formed in multiple directions to form vortices, and furthermore, the flow paths 131b- And vortexes are formed inside and outside the dissolved media 131b as the bend is formed.

With this structure, the dissolution rate can be further increased in the replenishing water of the malodorous gas. Various methods may be proposed to form the plurality of channels 131b-3 in which the dissolved media 131b are formed in a curved shape. However, as shown in FIG. 5b, a plurality of circular plates cross each other with different diameters, , And pressure heat distortion is applied at both ends in a direction of a large diameter so that each of the original plates forms a bend, and a plurality of bends formed by the bending can be formed.

On the other hand, as shown in FIG. 7, the decomposition media 132 is a spherical structure having a plurality of voids (not shown in the figure), and the dissolved media 131 is passed through while forming a vortex in the water to be replenished. . Therefore, the microorganism can live in the degradation medium 132 and can grow by the stored moisture.

In the case of this decomposition medium 132, two embodiments are presented in the present invention, and the structure is the same, but the composition is different.

First, as a first embodiment, the decomposition media 132 is characterized by being blended with 100 parts by weight of clay, 20 to 40 parts by weight of bottom ash, 5 to 15 parts by weight of water and 0.1 to 0.5 parts by weight of a curing agent. The decomposition media 132 according to such a composition is manufactured into a spherical shape in which water and a soil hardening agent are mixed with clay and bottom ash which form a plurality of voids as a material itself, and then subjected to a sintering step to form uniform particles.

The bottom ash is generally divided into a fly ash and a bottom ash depending on the place where the fly ash is generated as a by-product in the coal-fired power plant, and the fly ash is generated in the combustion process The fine ash particles in the fly ash are discharged through the combustion furnace together with the combustion gas and occupy 80 to 85% of the total fly ash. The bottom ash falls down to the bottom of the boiler in the combustion furnace, Or less, and about 15 to 20% of the total fly ash is generated. This bottom ash is relatively inefficient for effective recycling, and its loading and storage are not only saturated, but most of it is landfilled.

Therefore, in the present invention, it is intended to utilize the fine voids possessed by the bottom ash itself as a carrier. Since the bottom ash has a low strength, it is mixed with the clay to form a spherical structure to form a plurality of micro voids, Thereby preventing the occlusion phenomenon.

In the case of clay, however, the strength is superior to that of bottom ash, but wear and washing are caused by water pressure and the like, and the life of the decomposition media 132 may be shortened. Therefore, the present invention aims to solve this problem by adding scoria excellent in strength in place of clay.

In the second embodiment, the decomposition media 132 is characterized by comprising 20 to 40 parts by weight of bottom ash, 5 to 15 parts by weight of water and 0.1 to 0.5 parts by weight of curing agent in 100 parts by weight of scoria. In the case of the decomposition media 132 according to such a composition, water and a soil hardening agent are mixed with scoria and bottom ash which form a plurality of voids by the material itself, and are subjected to a sintering step, And the durability of the decomposition media 132 is improved by the strength of the scoria.

The scoria is a kind of volcanic products. There are a lot of scoria in Jeju - do called as a pine as a volcanic eruption in Korea.

The scoria of Cheju Island is a volcanic rock with mixed volcanic rock, volcanic sand and other volcanic cones. About 75% of the components of scoria are silicon oxide (SiO2), aluminum oxide (Al₂O₃) and iron oxide (Fe₂O₃), as well as calcium oxide (CaO), magnesium oxide (MgO), potassium oxide (K ₂O) (Na2O) and nickel oxide (TiO2). The shape of the scoria is porous and the specific surface area is about 100m2 / g, which is relatively large, thus providing a good environment for microbial growth.

In addition, scoria is stable physico-chemically and biologically, has high mechanical strength and durability, and has economic advantages of using natural materials. That is, by adding scoria to the decomposition media 132, the environment for growing microorganisms can be formed by the porous material, and the durability is improved.

In addition, scoria has a pH of about 6 to 7, and is characterized in that the pH is elevated at an appropriate level. That is, excessive pH increase may cause inactivation of microorganisms and the like, which may lower the purification efficiency, so that the pH increase can be suppressed at an appropriate level by adding scoria.

The disassembled medium layer 122 composed of the dissolved media layer 121 and the disassembled media 132 constituted of the dissolved media 131 is arranged alternately upwardly along the deodorization vessel 110, 121 receives the malodorous material, and the infused water containing the malodorous material flows into the decomposed media layer 122 below and is stored in the decomposition media 132, and at the same time, the malodorous material contained by the microorganisms is decomposed.

Since the decomposition media 132 may increase the surface area depending on the size of the particles, if the particles are too small, the permeability may be lowered and the particles may be lost. Therefore, the decomposition media 132 may have a diameter It is preferable to have a shape in the range of 1 inch (inch) to 2 inches (inch). In order to improve the air permeability, a ball or a spherical shape is preferable. However, have.

On the other hand, the sprayer 140 is mounted on the deodorization layer 120, and the water sprayed from the sprayer 140 flows below the deodorization tank 110 through the deodorization layer 120 located below. As described above, the malodorous substances of the malodorous gas in the dissolved media 131 are accommodated in the replenishing water, and the replenished water flowing in the dissolved media 131 is adsorbed to the degradation media 132 in which the microorganisms are concentrated, The odorous substance is decomposed by

As the odor gas passes through the deodorization layer 120, the odorous substance is decomposed by the microorganisms, the odorous substance is removed, and the moisture-containing gas is introduced into the separator 150. The separator 150 removes moisture contained in the gas, and the purified gas from which moisture has been removed is discharged through an outlet 113 of the deodorization tank 110.

On the other hand, as described above, in the lower part of the deodorization tank 110,

It is preferable that the replenishing water stored in the collecting tank 101 is sprayed to the deodorizing layer 120 through the sprayer 140 and the replenishing water stored in the collecting tank 101 is pumped to the sprayer 140 for forced transport The circulation line 160 is constructed so that the replenishing water sprayed through the sprayer 140 has a circulation cycle in which it is collected again into the catchment tank 101 after passing through the deodorization layer 120. [ The water collecting tank 101 is provided with a water inflow line 170 for supplying water to the water collecting tank 101.

On the other hand, FIG. 5B shows a first deodorizing apparatus 100a which is another embodiment of the present invention. The first deodorizing device 100a of the present embodiment further comprises a top deodorizing layer 190 on the deodorizing layer 120 and a second spraying device 141 for spraying the replenishing water on the top deodorizing layer 190 So that various odor generating substances included in the odor gas are removed by the deodorization layer 120 and the upper deodorization layer 190, thereby maximizing the removal efficiency of the odor generating substance.

The medium 191 constituting the upper deodorization layer 190 may be made of various materials, but polyurethane balls, bio-carbon, etc. may be used.

A water inflow line 170a is formed in the second sprayer 141 and a nutrient tank 142 is formed in the water inflow line 170a. The replenished water is sprayed through the water inflow line 170a to the upper deodorization layer 190 through the second sprayer 141 and the sprayed water passes through the upper deodorization layer 190 and the deodorization layer 120, The water stored in the water collecting tank 101 is circulated through the circulating line 160 to the deodorizing layer 120 and the collecting tank 101. [

The nutrient tank 142 stores nutrients for promoting the cultivation of microorganisms to supply nutrients to the deodorizing layer 120 and the upper deodorizing layer 190. Although not shown in the drawings, Means to selectively supply the nutrients by controlling the concentration.

In the first deodorizing device 100a configured as described above, the types of the attached microorganisms in the upper deodorizing layer 190 and the deodorizing layer 120 are different. In the case of the upper deodorizing layer 190, microorganisms are combined to form volatile (H ₂ S) such as Thiobacillus sp in the case of the deodorization layer 120 and the water-soluble odor generating substance such as hydrogen sulfide (H ₂ S) .

For this purpose, it is preferable that the pH of the deodorization layer 120 is lower than that of the upper deodorization layer 190 in the first deodorization device 100a. The pH of the upper deodorization layer 190 is maintained at about 2 to 7 , And the pH of the deodorization layer 120 is maintained at 1 to 2 so as to control the growth conditions of the microorganisms.

To this end, the pH adjusting tank 180 is formed in the circulation line 160 so that the pH of the water to be circulated through the deodorization layer 190 is maintained to be strongly acidic and circulated. Further, in the case of the upper deodorization layer 190, it is necessary to maintain neutrality at a weak acidity, so that water is sprayed without circulation through the water inflow line 170a.

According to this structure, the odor gas flows into the lower part of the deodorization tank 110 through the inlet port 111 and the water-soluble odor generating substance such as hydrogen sulfide is sprayed to the sprayer 140 in the process of passing upward through the deodorization layer 120 The dissolved water sufficiently dissolves the water-soluble odor generating substance such as hydrogen sulfide while passing through the dissolved mediator layer 121, and the water in which the water-soluble odor generating substance is sufficiently dissolved is adsorbed in the dissociated mediar 132, so that microorganisms such as thiobacillus To be oxidized (i.e., removed).

In this case, the water-soluble odor generating substance such as hydrogen sulfide is sufficiently removed due to the double structure of the deodorization layer 120. To this end, the water to be sprayed through the sprayer 140 is adjusted to a pH Acidity of about 1 to 2, and circulation through the circulation line 160 should be performed.

Meanwhile, the volatile organic compounds and the like, which have not been removed from the deodorization layer 120, are removed by various microorganisms when passing through the upper deodorization layer 190. For this purpose, the upper deodorization layer 190 is provided with a water inflow line The replenishing water that is not circulated through the first sprayer 170a and the second sprayer 141 is sprayed to maintain the pH at about 2 to 7. Particularly, spraying through the second sprayer 141 is preferably sprayed intermittently so as to reduce the amount of replenishing water to reduce the mass transfer resistance, thereby improving the treatment efficiency by the microorganisms.

The pH adjuster 180 may be maintained at a reference pH by supplying NaOH periodically on the circulation line 160, for example.

In the present invention, the electrolytic bath 180a shown in Fig. 8 is shown as the pH adjusting bath 180 of another embodiment. Thus, the electrolytic bath 180a is configured to supply the water to the water collecting tank 101. That is, the electrolytic bath 180a supplies the acidic water to the collecting tank 101. [

A cathode electrode 183 and an anode electrode 184 are formed in the electrolytic bath 180a and partition walls 185 made of an ion exchange resin are interposed between the cathode electrode 183 and the anode electrode 184 And the electrolytic bath 180a is partitioned into an alkaline water producing chamber 181 and an acidic water producing chamber 182. [

The cathode electrode 183 and the anode electrode 184 are made of a platinum group metal such as platinum or iridium or a platinum group metal of platinum or iridium or a mixture thereof in titanium or stainless steel.

As the electrode materials of the cathode 183 and the anode 184, electrons are actively transported between the electrodes by electrolysis, and in order to facilitate the oxidation, a material such as titanium, which is difficult to oxidize, is selected, It is preferable to platinum or iridium. Further, since the polarity of the power source may be switched, it is preferable to apply the same plating to both the positive electrodes.

The partition 185 is made of an ion exchange resin and prevents mixing of the alkaline water and the acidic water generated in the alkaline water production chamber 181 and the acidic water production chamber 182, The material is a known material and its explanation is omitted.

Particularly, in the present invention, an anion coating layer 186-1 having an anion exchanger 186-1 on the side exposed to both sides of the partition 185, that is, the side exposed to the alkali water producing chamber 181 and the acidic water producing chamber 182, And an ion exchange portion 186 composed of a coating layer 186-2.

Here, the anion coating layer 186-1 is characterized by having an anion exchanger, and the cation coating layer 186-2 is characterized by having a cation exchanger. The anion coating layer 186-1 and the cation coating layer 186-2 are formed by dissolving a resin having an anion exchanger and a cation exchanger in an organic solvent and applying the solution to both sides of the partition 185.

The anion exchanger may be a primary amine group, a secondary amine group, a tertiary amine group, a quaternary ammonium group, a polyethyleneimine group, or a phosphonium group, and the cation exchanger may be a sulfonic acid group, a phosphoric acid group or a carboxylic acid group .

The ion exchange portion 186 is formed on both sides of the partition 185 to guide only selected ions to the alkaline water production chamber 181 and the acidic water production chamber 182, The contact resistance (Rc) due to the generation of the interface between the ion exchange membrane and the barrier rib, and the like can be prevented.

8, an anion coating layer 186-1 is applied to both surfaces of the partition 185 to discharge acidic water, and an electrolyte solution is introduced into the electrolyte solution inlet communicating with the partition 185, So that the water is supplied to the inlet of the chamber 181 and the acidic water producing chamber 182.

Here, as an example of the electrolyte solution, an example using a solution in which NH4OH is dissolved in the replenishing water is presented. The hydroxide ions OH- flow from the electrolytic water flowing into the partition 185 to the acidic water production chamber 181 by an electric force and the hydroxide ions OH- of the alkaline water production chamber 182 also generate acidic water And moves to the chamber 181.

Also, as shown in the figure, the water (H 2 O) is also electrolyzed and the hydroxide ion (OH -) moves to the acidic water producing chamber 191. Therefore, the hydroxide ion (OH-) is increased in the acidic water producing chamber 181 to generate acidic water. At this time, the partition 185 functions to allow the hydroxide ion (OH-), which is an anion, to flow easily into the acidic water producing chamber 191.

Acid water is supplied to the water collecting tank 101 due to the action of the electrolytic bath 180a as described above (in this case, the alkaline water from the alkaline water producing chamber 181 is not shown in the drawing, The supply water sprayed from the water collecting tank 101 is acidic and is advantageous for the growth and decomposition of microorganisms. Of course, the alkaline water can be selectively supplied, and the pH and the redox potential can be changed by changing the current and the voltage.

As described above, the second deodorization device 200 defines an activated carbon adsorption tower, and an activated carbon layer is formed therein to physically remove the odor generating substance by adsorbing the odor substance contained in the odor gas into the activated carbon .

As described above, when the second deodorization apparatus 200 is used with the patent No. 1130323, "activated carbon adsorption tower ", a plurality of activated carbon layers are formed in a multi-layer structure to adsorb and remove odor generating substances from the odorous gas, . The detailed configuration is already registered and its explanation is omitted.

9, the monitoring unit 800 may be configured to remotely monitor the odor gas treatment state by the first deodorizing device 100 and the second deodorizing device 200, It can be detected automatically.

The monitoring means 800 includes a first sensor unit 810 formed in the gas inlet line 300, a second sensor unit 820 configured in the gas discharge line 500, a first sensor unit 810 And a central server 830 connected to the second sensor unit 820 by wire or wireless.

The concentration of the odor gas before the treatment by the first deodorizing device 100 and the second deodorizing device 200 and the concentration of the odor gas after the treatment are respectively set to the first sensor part 810 And the second sensor unit 820, and transmits the sensed values to the central server 830 by wire or wireless. The central server 830 transmits the sensed values, It is checked whether the first deodorizing device 100 and the second deodorizing device 200 are operating properly.

At this time, if the value measured by the second sensor unit 820 is equal to or greater than the threshold value, the central server 830 causes the manager or the user to automatically transmit a warning message so that the manager or the user 840 can directly It is possible to monitor whether the first deodorizing device 100 and the second deodorizing device 200 operate.

Here, the threshold value is a preset value. If the difference between the input value and the output value is equal to or more than a predetermined value, it is estimated that there is an abnormality in the first deodorizing device 100 or the second deodorizing device 200 It is a value that can be done.
