Livestock air purifier {Wet scrubber module of pig house}

The present invention relates to an air purifier, and more specifically, to a livestock house air purifier that purifies the internal air of a livestock house using circulating water.

In general, in livestock breeding places such as pig houses, chicken houses, or livestock sheds (hereinafter referred to as “livestock houses”), if the disposal of livestock excrement or sewage is not performed in a timely manner, Bad odor is generated by gases such as hydrogen sulfide, ammonia, methyl mercaptan, methyl sulfide, methyl disulfide, amines, acetaldehyde, etc. generated from the excrement.

If this odor is inhaled into the respiratory tract of livestock for a long period of time, it causes death of livestock, and causes stress in livestock, causing problems such as poor growth and pregnancy of livestock.

In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. This example is provided to more completely explain the present invention to those with average knowledge in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that identical members in each drawing may be indicated by the same reference numerals. Detailed descriptions of well-known functions and configurations that are judged to unnecessarily obscure the gist of the present invention are omitted.

Figure 1 is a schematic diagram schematically showing a pig pen air recirculation ventilation system 1 to which the air purifier 100 of the present invention is applied, and Figure 2 is a schematic diagram schematically showing the configuration of the air purifier 100.

As shown, the air purifier 100 of the present invention can be applied to barns where various types of livestock, such as pig farms, are raised. In particular, as shown in FIG. 1, it can be applied to the pig house air recirculation ventilation system 1 that recirculates the inside air of the pig house and can be used to purify pollutants such as ammonia contained in the inside air A1.

As shown in FIG. 1, the pig pen air recirculation ventilation system (1) includes an air purifier (100) that purifies the internal air (A1) discharged from the pig pen (10) to remove contaminants, and an air purifier (100) that removes contaminants discharged from the air purifier (100). An external air mixer (200) that mixes the purified air (A2) with external air (A) to adjust the carbon dioxide concentration of the purified air (A2), and the external air mixed air (A3) discharged from the external air mixer (200). A heat exchanger (300) that controls the temperature using solar energy, a UV sterilizer (400) that sterilizes disease-causing bacteria in pigs using the temperature-controlled air (A4) discharged from the heat exchanger (300) using a UV lamp, and a UV sterilizer (400) that controls them. Thus, it includes a control unit 600 that controls the air quality and temperature of the air inside the pig pen 10.

The pig house air recirculation ventilation system (1) is connected to the pig house (10) where pigs (P) are raised, purifies the internal air (A1) discharged from the pig house (10), and then recirculates it to the pig house (10). Controls the quality and temperature of the internal air.

The pig pen air recirculation ventilation system (1) minimizes the inflow of external air (A), purifies the internal air (A1), mixes some of the external air (A), and resupplies it to the pig pen (10). Accordingly, the mixing ratio of the warm and polluted internal air (A1) and the cold but fresh external air (A) is adjusted to circulate the appropriately mixed treated air and re-supply it to the pig house (10) to prevent the inflow and outflow of disease and odor. (10) It has the advantage of minimizing the energy load consumed to heat the internal air.

In addition, the energy consumed to additionally heat the internal air uses solar energy, which has the advantage of minimizing management costs consumed for heating.

Here, the air purifier 100 of the present invention is designed with a capacity to sufficiently remove contaminants by contacting the internal air (A1) with the circulating water (W), and does not affect the internal environment of the pig pen (10). It was designed with ventilation load in mind. Accordingly, the air quality of the treated air re-supplied to the pig pen 10 can be treated to be suitable for raising pigs.

The air purifier 100 of the present invention removes contaminants and dust contained in the internal air (A1) discharged from the pig pen (10) by contacting it with liquid circulating water (W).

Figure 2 is a cross-sectional schematic diagram schematically showing the cross-sectional configuration of the air purifier 100. As shown, the air purifier 100 has a casing 110 having an inlet 111 through which internal air (A1) flows in and an outlet 115 through which air purification completed air purification (A2) is discharged at both ends. And, a plurality of circulating water injection pipes 120 arranged vertically at regular intervals along the direction of movement of the internal air (A1) inside the casing 110 and the adjacent circulating water injection pipes 120 are disposed between circulating water ( A filler layer 130 in which W) is absorbed, an eliminator 140 provided between the circulating water injection pipe 120 and the outlet 115 to remove the circulating water (W) floating therein, and a casing 110. ) and a circulating water tank 150 in which waste circulating water (W1) is collected, a circulating water supply pipe 160 connecting the circulating water tank 150 and the circulating water injection pipe 120, and a circulating water supply pipe ( It includes a circulating water pump 170 that supplies circulating water (W) to 160).

The casing 110 is formed in the form of a closed enclosure with both ends open. The inlet 111 is connected to the exhaust fan 11 of the pig pen 10 and the internal air discharge pipe 112, and the outlet 115 is connected to the external air mixer 200 and the purified air inlet pipe 210.

The inlet 111 is provided with an internal air inlet fan 113 that applies pressure so that internal air (A1) flows in, and the outlet 115 is provided with pressure so that purified air (A2) moves to the purified air inlet pipe 210. A purified air blowing fan 117 that applies is provided.

Inside the casing 110, a plurality of circulating water injection pipes 120 are arranged at regular intervals perpendicular to the direction of movement of the internal air A1. The circulating water injection pipe 120 is provided with a length that can reach from the outside of the casing 110 to the bottom of the casing 110. A plurality of circulating water injection pipes 120 are connected to the circulating water supply pipe 160 to receive circulating water (W).

A plurality of spray nozzles 121 are provided at regular intervals on the plate surface of the circulating water injection pipe 120. The injection nozzles 121 spray circulating water W horizontally toward the moving direction of the internal air A1. At this time, the injected circulating water (W) is sprayed into the internal air (A1) and is simultaneously absorbed into the filler layer 130 disposed in the front.

The circulating water (W) comes into contact with the internal air (A1) and dissolves the water-soluble odor components contained in the internal air (A1). Hydrogen sulfide and ammonia, which cause most bad odors, are mostly dissolved and removed when they come into contact with circulating water (W). The waste circulating water (W1) in which the odor component is dissolved falls to the bottom of the casing (110) and is then collected in the circulating water tank (150).

The air purifier 100 of the present invention adopts a cross-flow system in which the moving direction of the internal air (A1) and the moving direction of the circulating water (W) are perpendicular to each other. This is to prevent the nozzle from being clogged by dust contained in the internal air (A1) and to enable smooth flow of internal air.

However, in some cases, it may be provided in a co-flow method or a retrograde flow method.

Figure 3 is an example diagram showing a process of cleaning the internal air (A1) after the circulating water (W) sprayed from the spray nozzle 121 is absorbed into the filler layer 130.

In the air purifier 100 of the present invention, filler layers 130 are alternately arranged between a plurality of circulating water injection pipes 120 arranged adjacently. The filler layer 130 absorbs the circulating water (W) sprayed from the spray nozzle 121 and increases the contact time and contact area between the internal air (A1) and the circulating water (W), thereby improving cleaning efficiency.

The circulating water (W) absorbed in the filler layer 130 flows down the filler layer 130 and comes into contact with the internal air (A1) moving horizontally, and cleans the odor components of the internal air (A1). Here, it is desirable that the spray nozzle 121 is capable of uniformly spraying the circulating water (W) into a wide space.

Figure 4 is an exemplary diagram showing examples of various spray nozzles 121. The spray nozzle 121 is a spiral type nozzle 121 shown in (a) of FIG. 4, a full cone type nozzle 121a shown in (b) of FIG. 4, and (c) of FIG. 4. The hollow cone type nozzle 121b shown may be used. Each spray nozzle 121 is arranged to sufficiently wet the filler layer 130 provided at the front or rear.

The filler layer 130 absorbs the circulating water (W) sprayed from the spray nozzle 121, and the internal air (A1) moving through the inside comes into contact with the absorbed circulating water (W) and removes odor components. . The filler layer 130 is disposed between the circulating water injection pipes 120.

The filler layer 130 allows gas, which is internal air, and liquid, which is circulating water, to come into contact and remove contaminants.

Contaminants contained in the internal air (A1) generated in the pig pen (10) contain a large amount of ammonia. In the case of ammonia, the material transfer coefficient is high because the Henry constant is high, and even if only water is used as the circulating water (W), the cleaning efficiency can be high in the filler layer 130.

The filler used in the filler layer 130 requires continuous management and replacement. Figure 5 is an exemplary diagram showing the types of fillers used in the filler layer 130 of the present invention. The filler may be a random type as shown in (a) of FIG. 5 or a structured type as shown in (b) of FIG. 5, respectively, or may be used in combination.

Because the structural type has low pressure loss, it has the advantage of being able to be used without significant pressure loss in both maximum and minimum ventilation. However, compared to the random type, there is the inconvenience of having to replace the entire filling material when problems such as clogging or damage occur. there is. Therefore, it is desirable to use an appropriate mixture of the two types of fillers.

The eliminator 140 is provided at the rear of the casing 110, that is, between the filler layer 130 and the purified air blowing fan 117. The eliminator 140 is a device that separates gas and liquid and removes the circulating water (W) moving along the direction of movement of the internal air (A1) inside the casing (110).

When the purified air (A2) from which contaminants have been removed is moved inside the casing (110), the humidity of the purified air (A2) is improved when the circulating water (W) is moved along with it. If the humidity of the purified air (A2) is improved, when the treated air (A5) is re-introduced into the pig pen (10), the humidity inside the pig pen (10) may increase and an unfavorable environment for pig breeding may be created.

To prevent this, the eliminator 140 removes circulating water (W) droplets floating inside the casing 110. Figure 6 is an example diagram showing various types of eliminators 140. The eliminator 140 is a wire mesh type as shown in (a) of FIG. 6, a packed bed type as shown in (b) of FIG. 6, and a zigzag type as shown in (c) of FIG. 6. A baffle type may be used.

The circulating water tank 150 is provided at the lower part of the casing 110 and communicates with the bottom of the casing 110. The circulating water tank 150 stores a certain amount of circulating water (W), and inside the casing 110, waste circulating water (W1) in which contaminants are dissolved in contact with the internal air (A1) is collected.

The circulating water tank 150 is connected to the circulating water injection pipe 120 through the circulating water supply pipe 160 and supplies circulating water (W) to the circulating water injection pipe 120. The circulating water supply pipe 160 is equipped with a circulating water pump 170 to move circulating water (W) along the circulating water supply pipe 160.

At this time, the circulating water pump 170 is equipped with a chemical solution supply tank 171 that supplies a chemical solution for disinfecting the waste circulating water (W1). The chemical solution supply tank 171 supplies a certain amount of chemical solution to the circulating water supply pipe 160 to neutralize the waste circulating water (W1) supplied to the circulating water supply pipe 160.

Here, the circulating water (W) removes water-soluble odor components, especially ammonia. Ammonia is better removed the lower the pH, and complex odors are easily removed by chlorine substances such as HOCL. Accordingly, the circulating water (W) may be one or more of slightly acidic electrolyzed water and sodium bisulfate.

At this time, sodium bisulfate is used by mixing with water and adjusting the pH to 1-2.

The operation process of the livestock air purifier 100 according to the present invention having this configuration will be described with reference to FIGS. 1 to 3.

When the exhaust fan 11 and the inlet fan 13 of the pig pen 10 are driven, the internal air (A1) of the pig pen 10 flows into the inlet 111 of the air purifier 100 through the internal air discharge pipe 112. do. As shown in FIG. 2, the internal air (A1) is moved into the casing 110 by the operation of the internal air inlet fan 113.

At this time, the waste circulating water (W1) in the circulating water tank 150 is moved to the circulating water supply pipe 160 by the circulating water pump 170, and is mixed with the chemical solution and neutralized. The neutralized circulating water (W) is distributed to a plurality of circulating water injection pipes (120) along the circulating water supply pipe (160).

The circulating water (W) distributed to the circulating water injection pipe 120 is injected through the injection nozzle 121.

As shown in FIG. 3, the circulating water (W) sprayed from the injection nozzle 121 is absorbed into the filler layer 130, the internal air (A1) moves through the filler layer 130, and the circulating water (W) comes into contact with

In this process, contaminants including ammonia contained in the internal air (A1) are dissolved and removed.

The waste circulating water (W1) in which contaminants are dissolved falls to the bottom of the casing (110) and is then collected in the circulating water tank (150). Then, after being mixed with the chemical solution through the circulating water pump 170, it is circulated in a circulation path that moves to the circulating water injection pipe 120 through the circulating water supply pipe 160 and cleans the internal air (A1).

Meanwhile, the internal air (A1) is moved in contact with the plurality of filler layers (130) by the blowing pressure of the purified air blowing fan (117), and in this process, it comes into contact with the circulating water (W) and most of the contaminants are cleaned. is removed. The purified air (A2) from which contaminants have been removed flows into the external air mixer (200) through the purified air inlet pipe (210).

Here, the air purifier 100 according to a preferred embodiment of the present invention has been described as being coupled to the pig pen 10, but in addition, it can be coupled to various types of livestock barns and used to purify the contaminated internal air of the livestock barn.

In addition, the air purifier 100 of the present invention may operate as a part of the pig pen air recirculation ventilation system 1, but in some cases, it may be used alone to purify the internal air.
