Description

Air purification device and air purification system including same

[0001] The present invention relates to an air purification device and an air purification system including the same, which can reduce odors inside a livestock shed, minimize odors emitted to the outside, and prevent deterioration of the health of livestock living inside the livestock shed and the health of workers working inside the livestock shed.

[0002] Currently, most air purifiers used in human living spaces use filters.

[0003] If these air purifiers are used inside livestock farms, where complaints about foul odors are the highest, the poor environment inside the livestock farm makes it difficult to maintain the device's performance due to early damage, making it difficult to use air purifiers in livestock farms that are similar to those used in human living environments.

[0004] Furthermore, currently, purification devices for odor reduction in livestock farms primarily target external odor emissions. These devices utilize a variety of technologies to reduce odors, including the use of chemicals like hypochlorous acid to capture odors, dilution with air fresheners, dust collection using odor collectors, capture and combustion using wet and dry scrubbers, bio-curtains utilizing microbial odor reduction, and the capture and emission of odorous substances using water sprays.

[0005] Existing odor reduction devices such as this are installed outside the livestock house to minimize complaints caused by odor in the livestock house and operate by reducing the odor emitted from the livestock house to the outside.

[0006] In other words, existing odor reduction devices focus on external emissions, which leads to the problem of ignoring the respiratory health of livestock workers and livestock due to odor reduction inside the livestock farm.

[0007] In addition, there are various problems when installing / operating such devices for reducing external odor emissions inside livestock houses, making them difficult to use inside livestock houses. That is, when hypochlorous acid water is sprayed inside the livestock house to reduce odor, its toxicity is harmful to the lung health of livestock and workers, and in the case of dust collection devices, the high density of dust inside the livestock house easily saturates the filter, making it difficult to use for a long time. In the case of biocurtains, they require a large space for installation, making them difficult to install in narrow spaces inside the livestock house, and water spray has the disadvantage of increasing the humidity inside the livestock house, causing stress to livestock.

[0008] Meanwhile, temperature and humidity control within existing livestock sheds involves heating and cooling devices such as air conditioners. Heating systems, designed to regulate optimal activity levels for piglets, are primarily installed in the space where piglets reside, raising the temperature. To ensure optimal temperature and humidity for growing and fattening pigs and sows, air conditioners or cooling pads are installed to bring in cool air from outside.

[0009] However, the problem with this inflow of external wind is that it can cause diseases such as African swine fever, foot-and-mouth disease, epidemic diarrhea, and porcine reproductive and respiratory diseases to spread by bringing viruses and bacteria that cause diseases from outside into the livestock farm.

[0010] Therefore, a technology is needed to create a comfortable atmosphere inside a livestock house and minimize the occurrence of diseases through air circulation and air purification inside the livestock house.

[0011] The purpose of the present invention is to provide an air purification device and an air purification system including the same, which can reduce odor inside a livestock shed, minimize odor emitted to the outside, and prevent deterioration of the health of livestock living inside the livestock shed and the health of workers working inside the livestock shed.

[0033] The terminology used in the present invention is only used to describe specific embodiments and is not intended to limit the present invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In the present invention, it should be understood that the terms such as "comprise" or "have" are intended to specify the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, but do not exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof. Hereinafter, an air purification device and an air purification system including the same according to an embodiment of the present invention will be described with reference to the drawings.

[0034]

[0035] FIG. 1 is a block diagram illustrating an air purification device according to one embodiment of the present invention.

[0036] Referring to FIG. 1, an air purification device (100) according to one embodiment of the present invention may include a blower fan (110), a spray unit (120: 120a, 120b), a constant voltage generation unit (130: 130a, 130b), a plasma generation unit (140), a gas monitoring unit (150), a communication unit (160), a sensor unit (170), a heating and cooling unit (180), and a control unit (190).

[0037] The blower fan (110) allows the purified gas, from which the odor has been removed, to be discharged to the outside through the exhaust port (104, see Fig. 3), while allowing the odorous fluid containing the odorous gas and dust to which the odorous gas has been adsorbed to be introduced through the intake port (103, see Fig. 3).

[0038] The first spray unit (120a) sprays water onto the malodorous fluid introduced through the intake port (103) to capture dust that has absorbed malodorous gases contained in the malodorous fluid. The remaining water that has not captured the dust and the water containing fine dust particles that have fallen due to their small size and have not been captured are captured by the first filter mesh (105a, see FIG. 3) formed at the rear of the first spray unit (120a).

[0039] At this time, the first constant voltage generator (130a) provides constant voltage by using the first spray unit (120a) as the first electrode (e.g., + pole) and the first filter body (105a) as the second electrode (e.g., - pole), thereby generating an electric field between the first spray unit (120a) and the first filter body (105a) to promote the capture of water (moisture) that inhibits plasma generation.

[0040] The plasma generator (140) ionizes the odorous gas from which moisture has been removed by plasma treatment.

[0041] The second spray unit (120b) sprays water onto the ionized malodorous gas to capture the ionized malodorous gas. The excess water that does not capture the ionized malodorous gas is captured by the second filter mesh (105b, see FIG. 3) formed behind the second spray unit (120b).

[0042] At this time, the second constant voltage generator (130b) provides constant voltage by using the second spray unit (120b) as the first electrode (e.g., + pole) and the second filter net (105b) as the second electrode (e.g., - pole), thereby generating an electric field between the second spray unit (120b) and the second filter net (105b) to promote the capture of water (moisture).

[0043] The gas that has passed through the second filter (105b) becomes purified gas from which dust and odor-causing gases have been removed, and the purified gas flows into the heating and cooling unit (180) through the exhaust port (104). The heating and cooling unit (180) performs heating and cooling treatment on the purified gas and then discharges the purified gas that has undergone heating and cooling treatment into the livestock house. The heating and cooling unit (180) may be an air conditioner (so-called air conditioner).

[0044] The gas monitoring unit (150) collects by bypassing a portion of the odor gas flowing into the intake port (103), and collects by bypassing a portion of the purified gas discharged from the exhaust port (104), and then measures and compares the contamination concentration in the odor gas with the contamination concentration in the purified gas to calculate the amount of odor reduction according to the capture of the odor source, and the control unit (190) compares the calculated amount of odor reduction with a preset standard value to control the blower fan (110) to increase or decrease the amount of odor reduction.

[0045] The communication unit (160) transmits management data acquired by the purification device (100) to the local management server (200) via a wired or wireless communication network. The acquired data may be various control information performed by the control unit (190) and various measurement information measured by the sensor unit (170).

[0046] The sensor unit (170) includes a temperature sensor, a humidity sensor, an ammonia sensor, a hydrogen sulfide sensor, an ozone concentration sensor, etc. The sensor unit (170) uses these sensors to measure the temperature, humidity, ammonia, hydrogen sulfide, ozone concentration, etc. inside the livestock house and transmits the measured values ​​to the control unit (190), and the control unit (190) generates control information for driving the blower fan (110), spray unit (120: 120a, 120b), constant voltage generator (130: 130a, 130b), and plasma generator (140).

[0047] Among the above-described components (110 to 190), the blower fan (110), the spray unit (120: 120a, 120b), the constant voltage generator (130: 130a, 130b), the plasma generator (140), and the gas monitoring unit (150) can be installed in one housing (101, see FIG. 3). In addition, the sensor unit (170), the heating and cooling unit (180), the communication unit (160), and the control unit (190) can be installed in one livestock house in which the housing (101) is installed.

[0048] The detailed configuration of the air purifying device according to one embodiment of the present invention will be described below with reference to FIGS. 3 to 7.

[0049]

[0050] FIG. 2 is a block diagram illustrating an air purification system including an air purification device according to one embodiment of the present invention.

[0051] Referring to FIG. 2, an air purification system according to one embodiment of the present invention includes an air purification device (100: 100_1, 100_2, 100_3, ~, 100_n), a local management server (200), and a central management server (300), which are connected to each other through a wired or wireless communication network.

[0052] Air purification devices (100: 100_1, 100_2, 100_3, ~, 100_n) can be installed in each barn. That is, if there are n barns, n air purification devices can be installed, one in each of the n barns.

[0053] Management data acquired from each livestock farm can be transmitted to a local management server (200) via a wired / wireless communication network through a communication unit (160). The local management server (200) is a management server of the livestock farm area that comprehensively manages n livestock farms, and the air purification device (100) and the local management server (200) can be connected to each other via a short-range communication network. Of course, the present invention is not limited thereto.

[0054] Management data of n livestock farms received by the local management server (200) can be transmitted to the central management server (300) via a wired / wireless communication network. The central management server (300) is a management server of a service provider that provides air purification services, and can provide air purification services by receiving a request from a livestock farm operator and providing management information to the livestock farm operator's terminal using the management data transmitted from the local management server (200). The central management server (300) can also collect / analyze data from multiple livestock farms and provide related services.

[0055]

[0056] Next, an air purification device (100) according to one embodiment of the present invention will be described in detail with reference to FIGS. 3 to 7.

[0057] FIG. 3 is a detailed drawing of an air purification device according to one embodiment of the present invention, FIG. 4 is a drawing for explaining the operation process of the first spray unit, FIG. 5 is a drawing for explaining the operation process of the first filter body, FIG. 6 is a drawing for explaining the operation process of the plasma generation unit, and FIG. 7 is a drawing for explaining the operation process of the second spray unit.

[0058] Referring to FIG. 3, an air purification device (100) according to one embodiment of the present invention may include a housing (101), a blower fan (110), a spray unit (120: 120a, 120b), a constant voltage generator (130: 130a, 130b), a plasma generator (140), a gas monitoring unit (150) each installed at multiple locations of the housing (101), and a communication unit (160), a sensor unit (170), a heating and cooling unit (180), and a control unit (190) installed outside the housing (101) but inside the livestock house. Of course, depending on the design, the communication unit (160), the sensor unit (170), the heating and cooling unit (180), and the control unit (190) may also be manufactured to be integrated into one housing.

[0059] The housing (101) may be a frame having a predetermined shape, for example, a rectangular parallelepiped or a cylindrical shape, with a space formed therein. Inside the housing (101), a plurality of partition walls (102) are arranged in a zigzag pattern to form a flow path (F) for the malodorous fluid. In addition, an intake port (103) is installed on one side of the housing (101), and an exhaust port (104) is installed on the other side.

[0060] The intake port (103) and the exhaust port (104) are open portions of the housing (101), and an odorous fluid containing odorous gas and dust adsorbed by the odorous gas is introduced through the intake port (103), and a purified gas from which odor has been removed is discharged through the exhaust port (104).

[0061] In particular, a blower fan (110) is installed in the exhaust port (104). The blower fan (110) generates a differential pressure between the intake port (103) and the exhaust port (104), thereby causing fluid flow in the flow path of the malodorous fluid formed inside the air purification device (100). At this time, if the blower fan (110) is installed on the intake port (103) side, the performance deteriorates due to the adsorption of dust, so it is preferable that the blower fan (110) is installed on the exhaust port (104) side through which the purified gas is exhausted. The flow speed of the malodorous fluid can increase or decrease in proportion to the rotation speed of the blower fan (110).

[0062] A strainer (105: 105a, 105b) is installed between one bulkhead and its adjacent bulkhead. The strainer (105: 105a, 105b) is installed at the rear of the spray section (120: 120a, 120b).

[0063] A storage tank (106) is installed at the bottom of the housing (101). The storage tank (106) is formed with an open top so that falling water can be stored. Dust, ionized odor gas, etc., which are adsorbed by the odor gas captured by the water sprayed from the spray unit (120: 120a, 120b) fall by their own weight together with the water and are stored in the storage tank (106). In addition, excess water without capturing dust, water with adsorbed fine dust that is too small to fall into the storage tank (106), or excess water without capturing ionized odor gas are captured by a filter mesh (105: 105a, 105b), and then fall by their own weight and are stored in the storage tank (106).

[0064] The storage tank (106) can be connected to the spray unit (120: 120a, 120b) through a separate connecting pipe (not shown). The water that has captured the odor source stored in the storage tank (106) can be supplied to the spray unit (120: 120a, 120b) through the connecting pipe and sprayed as an odor gas. A filter and a pump for removing the odor source can be installed in the connecting pipe. At this time, the filter can be a HEPA (High Efficiency Particulate Air Filter), a mesh filter, or a filter. The HEPA filter is an air filter that removes foreign substances such as dust contained in a fluid, and has a capturing ability of 85 to 99.975% or more for particles of 0.3 μm (microns) depending on the grade, and the filter paper of the filter is mainly made of glass fiber with a diameter of 1 to 10 μm (microns). Of course, in addition to the HEPA filter, other filters such as mesh filters and filters that can be cleaned and reused may be installed.

[0065] The malodorous fluid introduced into the intake port (103) flows along the flow path (F) and sequentially passes through the first spray unit (120a), the first strainer (105a), the plasma generator (140), the second spray unit (120b), and the second strainer (105b) to remove the malodorous source, and then is discharged through the exhaust port (104). In addition, the exhaust port (104) is directly connected to the heating and cooling unit (180), so that the purified gas from which the malodorous source has been removed is supplied to the heating and cooling unit (180). Alternatively, depending on the temperature / humidity inside the livestock house, the gas may be discharged directly into the livestock house without being supplied to the heating and cooling unit (180).

[0066] The first spray unit (120a) is installed at the rear of the intake port (103) and sprays water onto the malodorous fluid flowing in through the intake port (103) to capture dust that has absorbed malodorous gas contained in the malodorous fluid. In addition, the excess water that has not captured the dust is captured by the first filter mesh (105a) formed at the rear of the first spray unit (120a).

[0067] At this time, as shown in FIG. 4, the first constant voltage generator (130a) provides constant voltage by using the first spray unit (120a) as the first electrode (e.g., + pole) and the first filter body (105a) as the second electrode (e.g., - pole), thereby generating an electric field between the first spray unit (120a) and the first filter body (105a) to promote the capture of water (moisture) that inhibits plasma generation.

[0068] That is, when a high voltage power source is applied to the first spray unit (120a), the dust contained in the malodorous fluid can be easily adsorbed into the water due to the attractive action between the charge of the water and the charge of the malodorous source. At this time, the other electrode is connected to the first filter body (105a) for capturing excess water, so that an electric field is formed between the first spray unit (120a) and the first filter body (105a). The dust captured by the water with a high charge due to the high voltage sprayed from the first spray unit (120a) falls by its own weight together with the water and is stored in the storage tank (106).

[0069] The first filter mesh (105a) may be formed of a porous material layer or a composite material layer for forming a porous structure. For example, it may be a mesh mesh structure formed by overlapping multiple layers of fine wire mesh.

[0070] In addition, the first filter body (105a) may be formed of a porous material layer having conductivity, or may be formed of a porous material layer in which a non-conductive material is coated with a conductive material.

[0071] In addition, the size of the mesh of the first filter mesh (105a) is sufficient to minimize the differential pressure between the inlet and outlet, so that a high pressure difference does not occur in the blower fan (110), that is, the size of the pores is large enough to allow water molecules to collide and attenuate their momentum. In the case of a HEPA filter with a small pore size, the differential pressure is large, which increases the pressure loss, which may be detrimental to efficiency.

[0072] The electric field formed between the first spray unit (120a) and the first filter net (105a) by the first voltage generator (130a) can easily capture water molecules and fine dust particles that are small in size and do not fall, as shown in FIG. 5, onto the first filter net (105a).

[0073] Meanwhile, some odorous gases may not be captured by the first spray unit (120a) and the first strainer (105a). Since odorous gases have a stable chemical structure, they may not be easily captured even if their momentum is reduced by the water spray or the first strainer (105a). In order to compensate for this, the present invention uses a plasma generator (140) to reform (ionize) odorous gases.

[0074] Referring to Fig. 6, the plasma generating unit (140) includes two electrodes (141) and a dielectric (142). The dielectric (142) is formed in a form that surrounds one of the electrodes (141), thereby forming a dielectric barrier discharge. Of course, the plasma generating unit (140) is not limited to the dielectric barrier discharge method.

[0075] The plasma generator (140) irradiates plasma onto the malodorous gas, thereby ionizing the gas by removing electrons from the outer shell of the malodorous gas. The discharge cycle of the plasma generator (140) can be adjusted to improve ionization efficiency and cool the discharge electrode. Various types of power sources, such as AC, DC, and pulse, can be used for plasma generation.

[0076] The second spray unit (120b) is installed at the rear of the plasma generator (140) and sprays water onto the ionized malodorous gas to capture the ionized malodorous gas. In addition, the excess water that does not capture the ionized malodorous gas is captured by the second filter mesh (105b) formed at the rear of the second spray unit (120b).

[0077] At this time, as shown in FIG. 7, the second constant voltage generator (130b) provides constant voltage by using the second spray unit (120b) as the first electrode (e.g., + pole) and the second filter body (105b) as the second electrode (e.g., - pole), thereby generating an electric field between the second spray unit (120b) and the second filter body (105b) to promote the capture of water (moisture).

[0078] The second constant voltage generator (130b) and the second filter (105b) are substantially the same as the first constant voltage generator (130a) and the first filter (105a) described above, so a repeated description is omitted.

[0079] The purified gas, from which the odor source has been removed and which has passed through the second filter (105b), is introduced into the cooling and heating unit (180) through the exhaust port (104).

[0080] The heating and cooling unit (180) performs heating and cooling treatment on the purified gas and then discharges the purified gas, which has undergone heating and cooling treatment, into the interior of the livestock house. The heating and cooling unit (180) may be an air conditioner (so-called air conditioner). The heating and cooling unit (180) may be equipped with an optional exhaust control device that allows direct discharge of the air from the exhaust port (104) into the interior of the livestock house when the temperature and humidity inside the livestock house are comfortable enough that the use of the heating and cooling unit is not necessary.

[0081] Meanwhile, when plasma treatment is performed in the plasma generating unit (140), ionized malodorous gases may be adsorbed onto the plasma electrode (141). For example, malodorous gases such as ammonia have a property of being ionized and adsorbed onto the plasma electrode. Such adsorption may deteriorate the performance of the plasma generating unit (140). Therefore, a separate spray unit (not shown) may be additionally installed, and water may be intermittently sprayed onto the plasma electrode (141) to remove the adsorbed malodorous gas ions. Alternatively, the nozzle direction of the second spray unit (120b) may be changed toward the plasma electrode (141), and then water may be sprayed onto the plasma electrode (141) to remove the adsorbed malodorous gas ions.

[0082] The gas monitoring unit (150) collects by bypassing a portion of the odorous gas flowing into the intake port (103), and collects by bypassing a portion of the purified gas discharged from the exhaust port (104), and then measures and compares the concentration of the odor source contained in the odorous gas with the concentration of the odor source contained in the purified gas to calculate the amount of odor reduction due to the capture of the odor source. The odor source may be, for example, ammonia, hydrogen sulfide, etc., and the gas monitoring unit (150) may include a gas sensor that measures the concentration of these odor sources.

[0083] The amount of odor reduction calculated by the gas monitoring unit (150) is transmitted to the control unit (190), and the control unit (190) can compare the calculated amount of odor reduction with a preset standard value and control the blower fan (110) to increase or decrease the amount of odor reduction.

[0084] If the amount of odor reduction is less than the reference value, the control unit (190) reduces the rotation speed of the blower fan (110) to reduce the flow speed of the odorous fluid. As the flow speed of the fluid decreases, the reaction time for capturing the odor source increases, thereby increasing the amount of odor reduction. Conversely, if the amount of odor reduction is greater than the reference value, the rotation speed of the blower fan (110) is increased to increase the flow speed of the odorous fluid. As the flow speed of the fluid increases, the reaction time for capturing the odor source decreases, thereby maintaining the amount of odor reduction at a certain level.

[0085] In addition, the control unit (190) can increase or decrease the amount of odor reduction by adjusting the magnitude of the voltage applied to the constant voltage generator (130: 130a, 130b).

[0086]

[0087] Meanwhile, the purification gas flowing into the cooling / heating unit (180) through the exhaust port (104) may contain ozone that has not been captured and removed within the housing (101) after being generated by plasma treatment in the plasma generation unit (140). This ozone may be supplied to the inside of the livestock house after undergoing cooling / heating treatment together with the purification gas. If the ozone concentration inside the livestock house exceeds the standard, it may have a negative impact on the health of livestock or workers inside the livestock house.

[0088] To prevent this, the control unit (190) can generate a control command to turn off the operation of the plasma generator (140) so that ozone is no longer generated when the ozone concentration value measured by the ozone concentration sensor reaches a reference value. Alternatively, the control unit (190) can generate a control command to classify the ozone concentration value into risk levels and adjust the operation time of the plasma generator (140) for each risk level so that the amount of ozone generated is reduced.

[0089] In addition, if the temperature / humidity inside the livestock house measured by the temperature sensor / humidity sensor is higher than the reference value, the control unit (190) can apply a high voltage to the constant voltage generator (130: 130a, 130b) to increase the adsorption efficiency of residual moisture, droplets, etc.

[0090]

[0091] A typical air purifier has a fan installed at the intake port (intake port) that draws in odors. When such an air purifier is used inside a livestock house, the fan installed at the intake port becomes contaminated with dust and other particles due to the poor environment inside the livestock house, which has the disadvantage of reducing durability.

[0092] Due to these issues, most air purification devices installed inside livestock houses rely on outside air to achieve optimal conditions, resulting in low efficiency. Specifically, cooling devices cool hot air from outside the livestock house before introducing it into the house. This cooling, in turn, reduces efficiency by cooling high-temperature air.

[0093] In contrast, the air purification device according to one embodiment of the present invention has the advantage of high efficiency because it operates in a recirculating manner by introducing air inside a livestock house and cools it using low-temperature air.

[0094] In addition, by installing an air purification device in front of the air conditioning unit, that is, by directly introducing the purified gas into the air conditioning unit (180) through the exhaust port (104), the occurrence of problems such as contamination and deterioration of the durability of the air conditioning unit can be minimized. More specifically, the problem of damage easily occurring when an unpleasant-smelling gas such as ammonia or hydrogen sulfide is introduced into the cooling coil of the air conditioning unit can be improved.
