The first and second inlets 31a and 31b connected to the first and second lines L1 and L2 are formed on the upper side of the stirring tank 31, and a cover 31c for opening and closing is installed on the upper side. A stirrer blowing fan 38 to be described later is supported on the cover 31c, and an opening 31d communicating with the inside of the stirring tank 31 is formed in the cover 31c inside the stirrer blowing fan 38.

The mixing nozzle 32 is installed on the upper part of the container 33 inside the stirring tank 31 and mixes the first and second chemical liquids M1 and M2 flowing into the first and second inlets 31a and 31b. It is discharged into the container 33 in the form of a chemical liquid mixture (M).

Receiving container 33, as shown in FIG. 3, has a large floor area to support a plurality of guide rods 34, and the bottom drains the chemical liquid mixture (M) to the surface of the guide rods (34). A drainage guide groove (33a) is formed.

The guide rod 34 is agitated while allowing the chemical liquid mixture (M) drained through the drain guide groove 33a to flow slowly to the bottom of the stirring tank 31, so that the first and second chemical solutions (M1) constituting the chemical mixture (M1) ( M2) reacts to continuously generate deodorizing gas.

The vortex guide pin 35 is formed on the surface of the guide rod 34 to vortex the chemical liquid mixture M flowing down the guide rod 34 as shown in FIG. 4 . Accordingly, the first and second chemical solutions (M1) (M2) in the vicinity of the vortex guide pin (35) are actively stirred, effectively generating a deodorizing gas.

The water level sensor 36 is installed on the side wall of the stirring tank 31 on the lower side of the guide rod 34, and detects the water level of the chemical liquid mixture (M) and generates a drain signal (S) for operating the drain pump (70). do. Accordingly, even if the first and second chemical liquids M1 and M2 continue to flow into the stirred tank 31 , the level of the chemical liquid mixture M accommodated in the stirred tank 31 may be constantly maintained.

The air inlet 37 introduces external air to the lower side of the guide rod 34 through the stirring tank 31 side, as shown in FIG. 2 . This air transports the generated deodorizing gas to the deodorizing gas supply duct 90 to be in contact with the circumference of the guide rod 34 .

The agitator blowing fan 38 is installed on the stirring tank 31 and pressurizes the deodorizing gas generated from the air and the chemical liquid mixture M introduced through the air inlet 37 to the deodorizing gas supply duct 100 .

By such agitator 30, it is possible to efficiently and continuously generate a deodorizing gas in the form of a gas as a deodorizing reactant.

The first metering pump 40 quantitatively supplies the first chemical solution M1 stored in the first chemical solution tank 10 to the stirrer 30 , and the second metering pump 50 is stored in the second chemical solution tank 20 . The second chemical solution (M2) is quantitatively supplied to the stirrer (30). The first and second metering pumps 40 and 50 supply the first and second chemical solutions M1 and M2 in a fixed amount so that the first and second chemical solutions M1 and M2 react completely in the agitator.

The circulation pump 60 always circulates the chemical liquid mixture (M) that accumulates on the lower side of the stirring tank 31 through one side and the other side of the stirrer 30, and through this process, the chemical liquid mixture is mixed again and deodorized gas. continue to create

In particular, since the chemical liquid mixture (M) can be stirred inside the agitator 30 by the circulation pump 60, a stirring blade consisting of a plurality of blades for physically stirring the chemical liquid mixture, or for rotating the stirring blade Since the driving motor is not employed, it is possible to implement a structure in which the receiving container 33 , the guide rod 34 , and the agitator blowing fan 38 as described above can be installed in the inner space of the stirring tank 31 .

The drain pump 70 is interlocked with the water level sensor 36 and drains the chemical mixture (M) accommodated in the agitator 30 by the amount of the first and second chemical solutions M1 and M2 flowing into the stirring tank 31 . and, accordingly, the water level of the chemical liquid mixture (M) accommodated in the stirred tank 31 is always maintained constant.

The retention reaction tank 80 allows the deodorizing gas and the malodorous gas to be neutralized and removed by retaining the deodorizing gas and the malodorous gas flowing through the malodorous gas supply duct 90 and the deodorizing gas supply duct 100, and then the odor components are removed. The removed air is exhausted through the exhaust pipe 81 . At this time, since the malodorous gas reacts in direct contact with the deodorizing gas in the gaseous form inside the retention reaction tank 80, it is possible to deodorize at a faster rate than the deodorizing material in the liquid or solid form, not in the gaseous form.

The gas sensor 120 is installed in the exhaust pipe 81 and senses the odor gas remaining in the exhausted air to generate an interlocking signal S for controlling the amount of external fresh air supplied through the agitator 30 . The interlocking signal (S) strongly operates the agitator blowing fan 38 inside the agitator 30 to generate a large negative pressure in the agitation tank 31, and accordingly, the inflow of external fresh air through the air inlet 37 is increased, and a large amount of introduced air is supplied to the deodorizing gas supply duct 100 together with the generated deodorizing gas. Accordingly, the fresh air from the outside is supplied to the deodorizing gas supply duct 100 together with the deodorizing gas, and as a result, the concentration of odors flowing into the retention reaction tank 80 is lowered.

That is, when the gas sensor 120 detects the odor gas remaining in the air exhausted through the exhaust pipe 81, the agitator blowing fan 38 is strongly operated to supply a large amount of fresh air together with the deodorizing gas. It is supplied through the duct 100, and as a result, fresh air from the outside is supplied to the retention reaction tank 80 to lower the concentration of the odor gas, and accordingly, the deodorizing gas deodorizes the odor gas more effectively.

As described above, according to the present invention, the first and second chemical solutions (M1) (M2) are mixed to generate a deodorizing gas as a deodorizing reactant, and then the deodorizing gas is used to directly contact the malodorous gas to proceed with the deodorization process. Since gas can be continuously generated, a large amount of odor gas can be continuously deodorized, and since deodorizing gas in gaseous form is used, deodorization is possible much faster than when the deodorizing reaction material is liquid or solid.

Although the present invention has been described with reference to one embodiment shown in the drawings, which is only exemplary, those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
