Description

Deodorizer management system for removing bad odors from breeding facilities}

The present invention relates to a deodorant management system. Specifically, the present invention relates to a deodorant management system, which purifies polluted air generated in breeding facilities such as livestock sheds or pig houses by treating and circulating it through a deodorant solution, while monitoring the odor removal effect and the degree of contamination of the deodorant solution. This relates to a deodorant management system for removing odors in breeding facilities that ensures efficient deodorant management and operation of deodorizing devices while continuously maintaining deodorizing performance by replenishing and replacing the deodorizing solution.

In breeding facilities such as livestock barns and pig farms, large amounts of odor-generating substances such as hydrogen sulfide, methyl mercaptan, and ammonia are generated due to livestock excrement. The odor that causes severe discomfort not only causes complaints from the surrounding area, but also causes recent environmental protection. Related laws and regulations are also being prepared.

Accordingly, various methods are being prepared to remove odor, and representative examples include cooling condensation method, high-temperature oxidation (thermal incineration) method, catalytic oxidation method, adsorption method, and biological treatment method.

Among these, the cooling condensation method is effective in removing high concentrations of odorous gases, but requires a lot of facility and operating costs. In addition, the adsorption method is less economical due to periodic replacement and treatment of the adsorbent, and the catalytic oxidation method is economical, but odors include lead, arsenic, antimony sulfur, mercury, zinc, iron oxides, or other catalyst derivatives during the catalytic oxidation reaction. There is a disadvantage that a pretreatment process is required because gas rapidly inhibits the activity of the catalyst.

Biological treatment is a technology that removes odorous substances by using the chemical decomposition ability of mixed microorganisms. It is a biofilm that decomposes odorous substances by adding odor-decomposing microorganisms directly to the feed or by microorganisms settled on the surface of filler particles. Although it is implemented in the form of a deodorizing device, it is not easy to continuously introduce and maintain microorganisms and create a living environment for microorganisms.

Accordingly, in recent years, methods have been developed to remove various harmful substances, including bad odors, from the air through water or deodorizing liquid containing deodorant ingredients. However, with long-term use, the aqueous solution used becomes contaminated and its performance inevitably deteriorates. There was a problem with expensive deodorants being wasted in the process of replacing and discarding the aqueous solution.

It is provided with a control unit 150 for control.

In the present invention, the deodorant is a liquid product that can remove odors from the air in contact and circulation by reacting with odor-causing substances such as ammonia, a representative livestock odor, and volatile fatty acids. Various deodorizing liquids can be applied, and are preferably Natural chemical solutions approved by the U.S. Environmental Protection Agency (EPA) can be used.

This deodorant is an absorbent material that removes odor components contained in circulating air. In the present invention, the natural chemical solution and It is configured to maximize reaction time with odors. The present invention is for efficient management of these various deodorants, and since various commercial deodorants can be applied, detailed description thereof will be omitted to prevent the purpose of the invention from being obscured.

The odor removal tank 110 is a reactor for removing odor components by circulating air from the agricultural and livestock breeding facility 200 containing compost and reacting with a deodorant, and is equipped with a fan 112 to maintain the breeding facility 200. The air supply pipe 111, which receives unpurified air from the ventilation port, is connected to the lower side, and the exhaust pipe 113, which discharges the purified air, is connected to the upper side, so that there is a gap between the air supply pipe 111 and the exhaust pipe 113. It is configured so that an odor removal reaction occurs in the space.

For this purpose, a spraying structure 114 with a plurality of nozzles is installed on the inner upper part of the odor removal tank 110 to evenly spray the deodorant supplied from the outside toward the lower side, and a ventilation portion is provided on the lower side of the spraying structure 114. A plurality of formed diaphragms are installed in layers to form a flow path in a zigzag direction, and the purification unit 115 is configured to increase the residence time of the air supplied from the supply pipe 111 as it moves toward the exhaust pipe 113. .

At this time, by spraying the deodorant in a fine size through the spray structure 114, the air passing through the purifier can sufficiently react with the deodorant, but the purifier ( 115) is filled with a plurality of pole rings (PALL RING, 116).

The pole ring 116 is a filling structure that has a deodorizing agent attached to its surface and can increase the contact area with air. It allows air to pass through, but is formed with a plurality of protrusions, through-holes, and a fin structure, so that it can be used when contact with unpurified air. It is designed to increase reaction efficiency with deodorants on the surface. The efficiency of the pole ring 116 can be further increased by being configured in various sizes rather than a single size. In the present invention, as known pole rings having various shapes can be applied, the specific shape thereof is not limited.

The deodorant sprayed from the injection structure 114 and passing through the purification unit 115 is collected in the receiving part 117 provided at the inner lower part of the odor removal tank 110, and the deodorizing agent contained in the receiving part 117 Rather than being discarded after one-time use, the agent is circulated and re-supplied to the spray structure 114, and is used in a continuous odor removal process while its performance is maintained.

The auxiliary tank 120 is provided on the side of the odor removal tank 110 and accommodates the amount of deodorant required for the odor removal process, that is, the operation of the odor removal tank 110. In a conventional device similar to the present invention that removes odors through a liquid deodorant and a reactor, only such an auxiliary tank 120 is generally provided, and the deodorizing effect is strong in the initial stage of adding the deodorant, thereby ensuring smooth odor removal. However, over time, the deodorant quickly becomes contaminated due to reaction with odor-causing substances and its odor removal performance continues to decline.

In this case, the deodorant contained in the auxiliary tank must be replaced, and in this process, all the various deodorants are discarded, resulting in a high cost of wasted deodorant.

In addition, as the performance monitoring and deodorant replacement work of these deodorants must be carried out directly by the manager, there are cases where the appropriate time is missed and odor removal is not smooth, and supplying a large amount of deodorants to the auxiliary tank is also cumbersome. It was raw.

For this purpose, in the present invention, a main tank 130 that accommodates the same deodorant but has a larger capacity than the auxiliary tank 120 is provided separately so that the deodorant can be easily replenished with the auxiliary tank 120 when necessary, and the operation process Minimize the waste of deodorants.

The transfer unit 140 basically transfers the deodorant from the auxiliary tank 120 to the injection structure 114 and performs an odor removal process, and at the same time, assists the deodorant collected in the receiving unit 117. Through transfer to the tank 120, the deodorant is circulated while maintaining its performance and can be used without waste. In addition, as an operation for replacing the deodorant, it is configured to discharge the deodorant from the auxiliary tank 120 to the outside and transfer the deodorant from the main tank 130 to the auxiliary tank 120.

At this time, in the case of the deodorant discharged externally from the auxiliary tank 120, natural discharge may be achieved by basically using an eco-friendly chemical solution, and if necessary, it may be transferred to a separate treatment tank and undergo a treatment process.

The transfer unit 140 can be configured in various forms for transferring the deodorant mentioned above, but in the embodiment of the present invention, in consideration of efficient operation of the system and simplification of facilities, a single transfer pump 141 is provided, and 3- It is configured to achieve the necessary transfer operation by appropriately opening and closing the three switching valves consisting of way valves.

The transfer pump 141 is basically located between the auxiliary tank 120 and the odor removal tank 110 and is configured to discharge the deodorant sucked in from one side to the other side.

The first switching valve 142 is configured to allow the transfer pump 141 to selectively inhale the deodorant from the auxiliary tank 120 and the main tank 130. That is, in the present invention, the transfer pump 141 basically performs a selection operation of sucking the deodorant from the auxiliary tank 120 or sucking the deodorant from the main tank 130 according to the direction of the first switching valve 142. It can be done.

The second switching valve 143 is connected to the discharge side of the transfer pump 141 and selectively discharges the deodorant to the outside or transfers it to the transfer pipe 145. That is, depending on the direction of the second switching valve 143, the deodorant discharged from the transfer pump 141 is discharged to the outside or is transferred through the transfer pipe 145 to the third switching valve 144, which will be described later. It is carried out.

The third switching valve 144 selectively supplies the deodorant transferred through the transfer pipe 145 to the injection structure 114 or the auxiliary tank 120. That is, according to the direction of the third switching valve 144, the deodorant transferred through the transfer pipe 145 is supplied to the injection structure 114 to allow the odor removal process to proceed, or to replenish it with the auxiliary tank 120. Perform selection actions.

In addition, the transfer unit 140 is sprayed from the injection structure 114, passes through the purification unit 115, and has a return pipe 146 that transfers the deodorant contained in the receiving unit 117 to the auxiliary tank 120. It is provided to ensure circulation of the deodorant contained in the auxiliary tank 120 during the odor removal process.

The control unit 150 is equipped to automate not only the odor removal process but also the replacement and replenishment of deodorants, and is composed in detail of a first level sensor 151, a second level sensor 152, and a third level sensor. It may include a sensor 153, a contamination sensor 154, an odor sensor 155, a memory 156, a learning unit 157, a setting unit 158, and a timer 159.

The first level sensor 151, the second level sensor 152, and the third level sensor 153 are the same level sensor for detecting the level of the received deodorant, and the first level sensor 151 is the main level sensor. The amount of deodorant in the tank 130 is determined by the second level sensor 152, and the third level sensor 153 is determined by the amount of deodorant in the auxiliary tank 120. It is configured to detect each.

The contamination sensor 154 is configured to measure the degree of contamination of the deodorant contained in the auxiliary tank 120, and can measure the concentration of the deodorant when the concentration changes as the deodorant reacts with odor components. If turbidity changes as it reacts with odor components, a method of measuring turbidity through a light emitting and receiving unit can be applied.

The odor sensor 155 is configured to monitor the smooth operation of the odor removal tank 110 and measures odor components in the air passing through the exhaust pipe 113. Sensors can be used to detect various odor-causing substances mentioned above, and are typically configured to measure ammonia.

The control unit 150 basically controls the performance of the deodorant circulating through the auxiliary tank 120 and the odor removal tank 110 during the odor removal process according to the measurement results of the pollution sensor 154 and/or the odor sensor 155. can be monitored. In addition, the deodorant that circulates at a set cycle using the timer 159 can be replaced, or the measurement results of the pollution sensor 154 or the odor sensor 155, or the measurement results of the pollution sensor 154 and the odor sensor 155. As it was determined that the performance of the deodorant was deteriorated due to a decrease in the concentration of the deodorant, an increase in turbidity, and an increase in odor substances in the air discharged from the odor removal tank 110, the deodorant in the auxiliary tank 120 was judged to have deteriorated. is discharged to the outside, and the deodorant in the main tank 130 is transferred to the auxiliary tank 120 at a set level and then controlled to be supplied to the injection structure 114.

In Table 1 below, the solid line, dotted line, and thick line shown in FIG. 1 show three main processes, namely, the odor removal process, the discharge process of the deodorant in the auxiliary tank 120, and the process of discharging the deodorant from the main tank 130 to the auxiliary tank 120. The operation relationship of the first switching valve 142, the second switching valve 143, and the third switching valve 144 according to the deodorant replenishment process is shown.

1st switching valve Second conversion valve Third switching valve Auxiliary tank discharge ON OFF X Auxiliary tank replenishment OFF ON ON Odor removal operation ON ON OFF

Since this series of operations can be automated through the control unit 150, easy system operation can be achieved by actually managing only the replenishment of the deodorant in the main tank 130, which has a large capacity.

In addition, for smooth operation in an environment with large seasonal temperature differences, such as in Korea, a temperature sensor 160 and a heater 170 are installed in the main tank 130, the auxiliary tank 120, and the receiving part 117, respectively. In addition, the control unit 150 reflects the measurement results of the temperature sensor 160 and operates the heater 170 before the deodorant is frozen, so that the malodor removal operation and system are smooth without freezing the liquid deodorant even in winter. Operation can be carried out.

In addition, the odor removal tank 110 is configured to remove not only bad odors but also various bacteria or viruses in the air, and includes an ultraviolet lamp 118 that sterilizes the air purified above the injection structure 114, and an ozone generator. (119) may be further included.

The ultraviolet lamp 118 and the ozone generator 119 need to be properly protected through a filter or blocking plate (membrane) to prevent the deodorant sprayed through the injection structure 114 from scattering, and are directed to the exhaust pipe 113. By allowing ultraviolet ray irradiation and ozone disinfection before discharge, the strong oxidizing power can decompose and sterilize various organic substances with double bonds without secondary pollution, as well as add deodorizing effects.

This series of odor removal and deodorant management processes can lead to more convenient and effective system operation by applying not only IoT but also artificial intelligence and big data technology.

As a configuration for this, the memory 156 stores a series of control signals and control result information controlled through the control unit over time, and the control signals and control results stored in the memory through the learning unit 157 By analyzing and learning information, it is possible to generate pattern information including the number of cycles, replacement, and replenishment cycles of deodorants according to the odor removal process. This pattern information is closely related to odor generation patterns according to operating environments such as season, temperature, and humidity conditions. It is obvious that there is a connection.

The setting unit 158 uses the pattern information generated through the learning unit 157 to program the control signal of the control unit 150 by adjusting the circulation, replacement, and replenishment cycle of the deodorant during the odor removal process, If odor generation is relatively weak due to seasonal or environmental factors, reduce the amount of deodorant circulated during the odor removal process and increase the replacement and replenishment cycle. Conversely, if odor generation is relatively strong, reduce the amount of deodorant circulated during the odor removal process. Effective system operation can be achieved by reducing replacement and replenishment cycles while increasing volume.

Through testing of the system of the present invention with the above-described structure, the applicant confirmed that a groundbreaking result was obtained in reducing ammonia gas, the main cause of bad odors generated in livestock houses, from 23ppm to less than 1ppm.

The rights of the present invention are not limited to the embodiments described above but are defined by the claims, and those skilled in the art can make various changes and modifications within the scope of the claims. This is self-evident.
