The malodor gas mixer 700 uniformly mixes odor gas generated in each of the plurality of malodor generating facilities 10 and 11, and then supplies the malodor gas to the neutralization module 100. 3, the odor gas mixer 700 is shown as a cross-sectional view. 3, the odor gas mixer 700 includes a housing 710, a malodor gas inlet pipe 720 connected to the housing 710, a malodor gas outlet pipe 730 connected to the housing 710, A malodorous gas mixing structure 740 installed in the housing 710 and a drain pipe 760 connected to the housing 710.

The housing 710 provides a mixing space 711 in which various types of odorous gases are mixed. A malodor gas inlet pipe 720 is connected to one side of the housing 710 and a malodor gas outlet pipe 730 is connected to the other side. A drain pipe 760 is connected to the lower portion of the housing 710. In the mixing space 711, a malodorous gas mixing structure 740 for uniformly mixing various kinds of malodorous gases is installed.

The malodor gas inlet pipe 720 is located at one side (left side in the figure) of the housing 710. The odor gas generated in the odor generating facilities 10 and 11 flows into the mixing space 711 provided in the housing 710 through the odor gas inlet pipe 720. In the present embodiment, it is assumed that there are two odor gas inlet pipes 720. The odorous gas having a different concentration generated in the other two malodor generating facilities 10 and 11 flows into the mixing space 711 through the two malodorous gas inlet pipes 720. In the present embodiment, it is explained that there are two odor gas inflow pipes 720, however, three or more odor gas inflow pipes 720 may be used and they are also within the scope of the present invention. In addition, only one odor gas inflow pipe 720 may be installed. When only one malodorous gas inlet pipe 720 is used, various odorous gases having different concentrations may be combined and introduced into the mixing space 711 in the housing 710 through the malodor gas inlet pipe 720.

The odor gas discharge pipe 730 is located on the other side (right side in the drawing) opposite to one side to which the odor gas inflow pipe 720 is connected in the housing 710. Various kinds of odorous gases mixed in the mixing space 711 in the housing 710 are discharged through the odor gas discharge pipe 730 and supplied to the neutralization module 100.

The odor gas mixture structure 740 is installed between the odor gas inlet pipe 720 and the odor gas outlet pipe 730 in the mixing space 711 formed in the housing 710. The two odorous gases having different concentrations respectively introduced through the two odor gas inlet pipes 720 are uniformly mixed while passing through the odor gas mixture structure 740 and then discharged through the odor gas outlet pipe 730.

The malodorous gas mixture structure 740 includes a plurality of gas mixture plates 730 arranged in order in the mixing space 711 in the direction from the malodor gas inlet pipe 720 toward the malodor gas discharge pipe 730 (751, 753, 755, 757). In this embodiment, the malodorous gas mixture structure 740 is disposed along the flow direction of the odorous gas, and the first gas mixture plate 751, the second gas mixture plate 752, the third gas mixture plate 753, (754) are arranged in order. Each of the four gas mixing plates 751, 753, 755, and 757 extends obliquely toward the odor gas discharge pipe 730 toward the inside from the wall surface of the housing 710. The gas mixing plates located relatively downstream of the adjacent two gas mixing plates 751, 753 (753, 577) (755, 757) pass through a guide plate located relatively upstream as shown for smooth mixing It is preferable to extend it. At least a portion of the gas mixture plates (in the present embodiment, the second gas mixture plate 753, the third gas mixture plate 755 and the fourth gas mixture 753, 753, 755, 757) 757 and 758 are formed at the ends of the plate 757 toward the upstream side in the flow direction. The bends 754, 756, and 758 are preferably curved as shown. The flow of the malodorous gas forms a vortex by the bent portions 754, 756, and 758, so that odorous gases having different concentrations can be uniformly mixed.

The drain pipe 760 is connected to the lower portion of the housing 710. The condensed water generated in the mixing process of odorous gases occurring in the mixing space 711 through the drain pipe 760 is discharged to the outside. The U-shaped pipe 765 is installed in the drain pipe 760 so that the odor can be prevented from being discharged to the outside by the water stored in the U-shaped pipe 765. Alternatively, a valve may be provided in the drain pipe 760 instead of the U-shaped pipe 765 to control the drainage of the condensed water.

The malodor gas mixer 710 described above as the constitutional center will be described below with reference to its operation.

The two malodorous gases generated at the two malodorous gas generating units 11 and 12 and having different concentrations are introduced into the mixing space 711 formed in the housing 710 through the two malodorous gas inlet pipes 720, do. The malodor gases flowing into the mixing space 711 flow toward the discharge pipe 730 and pass through the plurality of gas mixing plates 751, 753, 754 and 757 arranged in order along the flow direction, do. Especially, the high-concentration odor gas and the low-concentration odor gas can be uniformly mixed by the vortex formed by the bent portions 754, 756, and 758. High concentration odor gas and low concentration odor gas uniformly mixed while passing through the plurality of gas mixture plates 751, 753, 755 and 757 are discharged through the odor gas discharge pipe 730 and supplied to the neutralization module 100. Condensate water is generated in the course of mixing the odor gas in the mixing space 711, and the condensed water generated in the mixing process of the odor gas is discharged to the outside through the water pipe 760. Also, the 'U' shaped pipe 765 provided in the drain pipe 760 prevents odorous gas from being discharged to the outside through the drain pipe 760.

The neutralization module 100 dissolves and removes a part of the malodorous substances of mixed odor gas introduced from the malodor mixer 700 into water and includes an acidic neutralization module 1100 and an alkaline neutralization module 1200 .

The acidic neutralization module 1100 neutralizes acidic odor-causing substances such as hydrogen sulfide in the malodorous gas. The acidic neutralization module 1100 neutralizes the acidic odor-causing substances to neutralize the acid in the storage space, Remove it.

The alkali neutralization module 1200 neutralizes alkaline and odor-causing substances such as ammonia and threylmethylamine in the malodorous gas and neutralizes the alkaline water in the storage space by dissolving the alkaline odor-causing substances It serves to remove and remove acidic substances from the outside.

Meanwhile, the neutralization module 100 may be configured such that the acidic neutralization module 1100 and the alkali neutralization module 1200 are connected in series in response to the malodorous gas so that the malodorous gas is mixed with the acidic neutralization module 1100, Module 1200 to sequentially remove odor-causing substances.

Preferably, the neutralization module 100 is sequentially connected in series in the order of the acid neutralization module 1100 and the alkaline neutralization module 200. This is because, in the case of most of the odor gas, the content of the odor causing substance is high in order of alkalinity, acidity, and neutrality, which have alkalinity, but this is a preferable example, It goes without saying that the arrangement order of the processing units can be changed differently.

The neutral module 200 dissolves and removes the remaining odor-causing substances of the odor gas introduced from the neutralization module 100 into the water to remove the neutralization module 2100 and the reduction neutral module 2200 .

The neutralization module 2100 serves to neutralize the odorous gas by injecting an oxidant from the outside so as to oxidize and decompose the dissolved malodorous substances such as acetaldehyde, methyl sulfide, dimethyl disulfide, and methyl mercapic acid.

The oxidizing neutral module 2100 is often capable of removing an odorous substance that is difficult to remove with water or a neutralizing agent by an oxidizing agent. The oxidation reaction between oxygen and chlorine contained in the treating liquid and the odorous substance causes the odorless substance And is fixed within the treatment agent. Here, the oxidizing agent may cause a strong oxidizing action on HClO, and it is preferable to deodorize with sodium hypochlorite which is excellent in handling and economical efficiency. However, it is preferable that the oxidizing agent is a sulfide such as hydrogen sulfide, methyl mercaptan, methyl sulfide, methyl disulfide , Ammonia, trimethylamine, and the like, as long as it can attain the above objects.

In addition, the reduction neutral module 2200 reduces and removes the odor attributable to the oxidant, which is input from the oxidation neutral module 2100. That is, the reduction neutral module 2200 serves to remove the odor due to the ClO gas generated in the oxidant injected in the neutralization module 100 and the oxidation neutralization module 2100, Since the concentration of the introduced odor is not constant, it is difficult to input a substantially accurate amount of the oxidizer, so that an excess amount of the oxidizer may be injected. As a result, there is a gaseous substance which is weak in oxidation reaction. The reduction neutral module 2200 reduces and removes a malodorous substance generated by the oxidant.

Here, the neutral module 200 connects the oxidation neutral module 2100 and the reduction neutral module 2200 in series in response to the malodorous gas to remove the odor-causing substance, and the neutral neutral module 2100 And the reduction neutral module 2200 are sequentially connected in series in this order.

That is, the complex odor elimination facility 500 selectively removes the acidic neutralization module 1100, the alkali neutralization module 1200, the oxidation neutralization module 2100, and the reduction neutralization module 2200, The acidic neutralization module 1100 can stop the operation and operate only the other alkali neutralization module 1200 and the neutral module 200 corresponding to the component of the malodor causing material as shown in FIG. . Here, the acid neutralization module 1100 can not dissolve the malodorous substance of the malodorous gas in the water due to the stop of the operation thereof. However, the malodorous gas may be discharged to the outside through the blocking plate 1171 and the eliminator 1172 It is possible to miniaturize the malodorous gas and collect the moisture.

The gas line 300 is connected to the neutralization module 100 and the neutral module 200 so that the malodor gas is introduced into the neutralization module 100 and the neutral module 200, To be discharged.

In detail, the gas line 300 includes a supply line 310 for introducing the malodor gas from the malodor generation facility 10 to the neutralization module 100, A first gas line 320 connecting the neutralization module 1100 and the alkaline neutralization module 1200 to each other and a second gas line 330 connecting the neutralization module 100 and the neutral module 200 to each other, A third gas line 340 connecting the neutralization module 2100 and the neutralization module 2200 in the neutral module 200 to each other and a third gas line 340 connected to the outlet of the neutral module 200, And a discharge line 350 for discharging the malodorous gas to the outside.

The suction fan 400 is provided on the gas line 300 to suck and flow the malodor gas in the neutralization module 100 and the neutralization module 200, And serves to make the inside of the module 200 a negative pressure state.

Here, the suction fan 400 includes a first suction fan 410 installed on the first gas line 320, a second suction fan 410 installed on the second gas line 330, A third suction fan 430 installed on the third gas line 340 and a fourth suction fan 440 installed on the discharge line 350, 1 gas line 320, the second gas line 330, the third gas line 340, and the discharge line 350, respectively.

Referring to FIG. 4, the complex odor elimination facility 500a may install the fourth suction fan 440 only on the discharge line 350. In this case, the fourth suction fan 440 can increase the capacity of the neutralization module 100 and the neutral module 200 to be in a negative pressure state, and the negative pressure of the neutralization module 100 It is needless to say that a damper or the like may be provided for reinforcement.

In addition, the suction fan 400 can selectively operate each of the neutralizing module 100 and the neutral module 200 in addition to the above embodiments, taking into account the operation of the neutralization module 100 and the internal sound pressure state, Of course.

5, the gas line 300 may form a bypass line bypassing the respective suction fans 400, and may include a first bypass line 321, a second bypass line 321, 331, a third bypass line 341, and a fourth bypass line 351.

The first bypass line 321 communicates with the first gas line 320 at the front end and the rear end of the first suction fan 410 so that the malodor gas bypasses the first suction fan 410. [ .

The second bypass line 331 is communicated with the second gas line 330 at the front end and the rear end of the second suction fan 420 so that the odor gas bypasses the second suction fan 420, .
