More particularly, the present invention relates to a multi-stage vortex mixed pollutant gas deodorizing apparatus which is composed of a multi-stage pollutant gas and can deodorize and discharge the polluted gas with a different cleaning liquid through separate deodorizing rooms.

In general, in a place such as a sewage treatment plant, a manure treatment plant, a food treatment facility, a livestock facility, etc., various organic or inorganic gases are combined to generate a lot of odors.

In addition, in the place where the odor occurs, a separate deodorization device is installed to remove the odor, but because it is a deodorizing device made of one hollow has been used to remove the odor using only one drug.

However, these malodors are divided into basic series, acidic series, and neutral series, and because they are complex, there is a problem in that one drug cannot effectively remove the malodor.

In addition, the odor gas composed of a complex gas is usually washed by the neutralization reaction by 'acid and alkali', such a conventional deodorization tower is a separate deodorization tower, that is, acid or alkali washing tower respectively configured in series or parallel It was made, which is not a quick or limited problem in the hassle of construction production and deodorizing power of the composite gas, while the installation space was limited due to the large size of the device.

In addition, the formation process of the vortex in the second deodorizing part is similar in part.

5 is a main configuration diagram showing the first deodorizing unit operation of the multi-stage vortex mixing pollutant deodorizing apparatus according to the present invention.

Referring to FIG. 5, the first pollutant gas ejection tubes 50, 50a and 50b are arranged in one or more stages on the same vertical plane between the first ejection tubes 30 and at least one same level. It is installed on the surface. A plurality of upper stage first stages are installed at least one times deeper than the inlet diameter of the tube at the solution upper surface, and lower slope nozzles 60a and 60b are installed at the upper stage first stage.

From the second stage below the lower inclined nozzles 60a and 60b, horizontal nozzles 70 and 72 are arranged in one row in the horizontal center direction from the horizontal center line, and the lower inclined nozzles 80a and 80b in two rows downward. 80c) and 80d are provided.

On the other hand, the amount of spraying nozzles at each stage increases the number of injection nozzles so that the same amount is sprayed in the vortex state of the first cleaning liquid or the spraying amount is increased as it goes down to the lower stage, and the first spray pipe 30 and the first polluting gas powder The injection direction of the pipes 50, 50a and 50b is provided in one direction, whether clockwise or counterclockwise.

As shown in FIG. 5, the first deodorizing part is operated by the first cleaning liquid sprayed from the first injection pipe 30 to form a vortex between the outer body 102 and the inner body 104, and The polluted gas injected from the first polluted gas ejection pipes 50, 50a and 50b arranged at the lower end becomes bubbles and is absorbed and dissolved while being rotated by the vortex.

In addition, the first contaminant gas injection pipes 50, 50a, 50b are arranged in three stages between the first injection pipes 30 for jetting the first cleaning liquid, and at least one of them is installed on the same horizontal plane. The lower inclined nozzles 60a, 60b, horizontal nozzles 70, 72 and the lower inclined nozzles 80a, 80b, 80c and 80d of the contaminated gas are sprayed and scattered downward, horizontally and upwardly. As a result, a myriad of small bubbles (B) are produced, and the bubbles (B) are rotated by the vortices of the first washing liquid ejected from the first spray pipe (30), and numerous and small bubbles are removed by rapid destruction. As a result, the harmful substances of the polluted gas which have been injected are deodorized in response to the first cleaning liquid.

In this deodorizing process, the first cleaning liquid is sprayed horizontally through the first spray pipe 30 and at the same time forms a vortex between the outer body 102 and the inner body 104 based on the injection force, and the polluted gas is It is sprayed through the first pollutant gas ejection pipes 50, 50a and 50b arranged between the first spray pipes 30, but only downward in the upper first pollutant gas spray pipe 50, which is disposed at the top. The lower inclined nozzles 60a and 60b which can be sprayed are installed in two rows to form a downward spray in half-shape shape to form a strong vortex without disturbing the spraying force of the first cleaning liquid, so that the contaminated gas from the top is good. Is supplied.

In addition, the interruption gas injection pipe 50a disposed at the middle of the suspension is provided with horizontal spray nozzles 70 which can be sprayed horizontally in the horizontal center direction in one row, and downward inclined nozzles 80a and 80b which can be sprayed downward. ) Is installed in two rows, so that the spraying is made in the shape of half stalk, which causes the vortex with strong spraying force, thus maximizing the generation of the bubble body (B) to increase the deodorization efficiency with the first cleaning liquid sprayed from the first spray pipe (30). Maximize and reduce the bubble extinction distance of the polluting gas.

In addition, a lower inclined nozzle (80c) and a horizontal spray nozzle (72) which are sprayed in the horizontal direction and the downward direction are installed in the first pollutant gas spray pipe (50b) disposed at the lower side. The spraying force of the downward inclined nozzles 80a and 80b is mixed to form a strong spraying force between the first polluting gas spray pipes 50a and 50b, thereby deodorizing by the first cleaning liquid. Due to the lower partial yarns by the lower inclined nozzles 60a, 60b, 80a, 80b, 80c, and 80d, the pulverization of the bubbles due to the strong jet of the polluted gas is further promoted.

Therefore, in the vortex state of the first cleaning liquid, the first pollutant gas injection pipes 50, 50a and 50b have the same injection amount at each stage of the first stage, the second stage and the third stage. At this time, the injection speeds of the injection nozzles 60a, 60b, 70, 80a, 80b, 72, 80c and 80d of the first pollutant gas injectors 50, 50a and 50b of each stage are 1st stage> 2nd stage> 3rd stage, and the area of injection nozzles 60a, 60b, 70, 80a, 80b, 72, 80c and 80d is do.

In such a vortex of the first cleaning liquid, the spraying distance of the contaminated gas becomes 1 stage> 2 stage> 3 stages, and the gas-liquid contact length and time are longer than before. Deodorization efficiency is increased.

Therefore, the multi-stage vortex mixing pollutant deodorizing apparatus according to the present invention may deodorize the polluting gas twice through the first deodorizing unit 106 and the second deodorizing unit 108 or the filling layer 140. In addition, it is possible to deodorize the contaminated gas more efficiently by using different cleaning solutions, as well as to quickly deodorize.

Hereinafter, the performance of the multi-stage vortex mixing pollutant deodorizing apparatus according to the present invention and the conventional deodorizing apparatus in which only one conventional washing unit is formed were compared.

The experiment was conducted with caustic soda (NaOH) and sodium hypochlorite (NaClo) to observe the relationship between the structural characteristics of the deodorizer and the deodorization efficiency.
