In the inner upper portion of the reaction tower 3, the first and second adsorption layers (B ₁ ) (B ₂ ) composed of solid active cortides of different sizes are installed in a double top and bottom. Silver oxidized natural corrosive formed by the flora and fauna fluid was activated by redox potential of (+) 150mmV or more into spherical shape with diameter of 50 ~ 80mm, diameter of 1 ~ 3mm, length 3 The first adsorption layer (B ₁ ) is formed in the form of pellets having a size of ˜10 mm. The first adsorption layer (B ₁ ) is installed below the spherical solid, and the second adsorption layer (B ₂ ) is in the form of pellets. It is installed on the upper side as a corrosive.

In addition, the first and second adsorption layers (B ₁ ) (B ₂ ) are installed in a separated state by a nonwoven fabric made of polyvinylidene.

The upper portion of the reaction tower 3 is provided with a gas outlet 32 for discharging the gas from which the odor has been removed, and the drain valve 33 is installed at the lower side.

On the other hand, the embodiment of Figure 2 is the active corrosive solution (A) stored in the reaction tower (3) is sent from the odor generating source (1) is heated to the same temperature of the odor gas emitted from the blower 31 In order to install a heater (4) in which the temperature controller 41 is installed, and the odor generating source (1) and the reaction tower (3), the pump (5) and the spraying pipe (51) installed pumping line (52) By connecting the active corrosive solution (A) stored in the reaction tower (3) to the odor generating source (1) by connecting to the active corrosive solution (A) from the odor generating source (1) to the odor 3 shows that the blower 31 installed in the reaction tower 3 is installed on the water surface of the active corrosive solution A so that the blower 31 is not loaded with the odor gas. On the other hand, the active corrosive solution (A) is blown up (31), while the well working is smooth. To be injected into jangseol The injection pipe (6) to which the pump 61 is connected to the pumping line 62 jangseol.

The embodiment of Figure 4 is the first and second adsorption layer (B ₁ ) (B ₂ ) to remove the active corrosive solution (A) in the reaction tower (3) and consisting of a solid spherical or pellets of the active corrosive And a third adsorption layer made of granular activated carbon.

The operation according to the embodiment of the present invention configured as described above will be described.

First, the embodiment of Figure 1 is the first and second adsorption layer (B ₁ ) (B ₂ ) of the active corrosive solution (A) in the liquid phase and solid spherical and pellet-like active corrosive inside the reaction tower (3) Injected and installed, the blower (2) is operated to send the malodorous gas in the malodor generating source (1) to the diffuser (31) through the pipeline (21). The malodorous gas is contained in the active corrosive solution (A). In this case, the odor discharged from the acid pipe 31 is diffused in the state of fine bubbles, and the contact with the active corrosive solution (A) is activated to activate volatile base components such as ammonia or amines contained in the odor gas. , Trapped as a complex such as ammonia or amines, and the malodorous gas passed through the active corrosive solution (A) continues to pass through the first and second adsorption layers (B ₁ ) (B ₂ ) composed of solid active corrosive substances. In this case, in the liquid active corrosive solution (A) Volatile components containing unconjugated hydrogen sulfide are adsorbed and removed from spherical and pellet-like active corrosives constituting the first and second adsorbent layers. Thus, gas deodorized by liquid and solid active corrosive Is discharged into the atmosphere through the gas outlet (32).

2 is an embodiment in which the heater 4 is installed in the active corrosive solution A of the reaction tower 3, and this embodiment is suitable for treating high temperature and high odor gas such as food waste. , The heater 4 is heated by the operation of the temperature controller 41, so that the temperature of the active corrosive solution (A) to a temperature slightly higher than the temperature of the malodorous gas while being hot and humid from the blower (31) This is to prevent condensation from occurring when the malodorous gas passes through the active corrosive solution (A). Because if the temperature of the active corrosive solution (A) is lower than the temperature of the hot and humid odor gas emitted from the 31, condensation occurs in the process of passing the hot and humid odor gas through the active corrosive solution (A). This is because a large amount of condensate is generated, and for the purpose of preventing this, the embodiment of FIG. 2 is to prevent the generation of a large amount of condensate by heating the active corrosive solution A, and also to activate the active corrosive solution of the reaction tower 3 ( A) is pumped as a pump (5) and sprayed into the spray pipe (51) installed inside the odor source (1), thereby bringing the odor gas from the odor source (1) into contact with the active corrosive solution (A) to increase the deodorizing effect.

For example, when treating high temperature and high humidity odor generated from a lot of water, such as food waste, the odor itself contains a lot of moisture. Therefore, when the active corrosive solution (A) is passed through, the moisture contained in the odor is captured as condensate. As a result, the level of the active corrosive solution (A) is increased, and the air supply field is the first and the second adsorption layer (B ₁ ) (B ₂ ) and the third adsorption layer (B ₃ ) of solid spherical and pellet-like active corrosive. ) Has the disadvantage of causing flooding. Therefore, in order to remove the hot and humid odor gas generated from the food waste, the first and second adsorption layers composed of solid spherical and pellet-like active corrosives without injecting the active corrosive solution A from the reaction tower 3. (B ₁₎ it is a preferred method of removing the odor gas as a means for jangseol the third adsorption layer (B ₃₎ consisting of (B ₂₎ and particulate activated carbon.

On the other hand, in the embodiment as described above, in the process of continuously deodorizing, removing the odor gas generated from the odor generating source (1), water is accumulated in the bottom of the reaction tower (3) or the liquid active corrosive solution (A) When it becomes contaminated and cannot function properly, the drain valve 33 is opened and drained, thereby continuing to process the odor gas.

According to the present invention as described above, the cleaning action using the active corrosive liquid and the adsorption action by the solid spherical and pellet active corrosive are continuously performed in one reaction tower, thereby effectively eliminating various odors such as ammonia, hydrogen sulfide, and amines. In addition, the deodorizing device of the present invention can be miniaturized by being composed of a single reaction tower, and is manufactured with a simple structure in which an active corrosion solution and a solid active corrosion material are injected and installed inside the reaction tower. Therefore, it is possible to drastically reduce the operating cost and maintenance pipe cost as well as the installation cost, and the active corrosive solution and the solid active corrosive used to remove the odor are also practically designed to provide the advantages that can be finally utilized as soil improving agent. to be.
