Description

Deodorizing device for organic waste treatment plant

[0001] The present invention relates to a deodorizing device for an organic waste treatment device, and more particularly, to a deodorizing device for an organic waste treatment device that can prevent air pollution by removing odor and harmful gas components contained in water vapor generated from a device that hydrolyzes and treats organic waste by spraying microorganisms, and by capturing carbon dioxide through a zeolite layer, thereby discharging harmless gases to the atmosphere, and that can deodorize without chemical treatment, thereby preventing secondary pollution and enabling an eco-friendly circulation.

[0002] Recently, as the number of livestock raised in the livestock industry increases, the amount of livestock waste (livestock manure, livestock carcasses, etc.) generated is also increasing. Accordingly, livestock farms are facing serious odors caused by livestock waste, and livestock waste contains a large amount of moisture, making it difficult to compost. In addition, if it is discharged into a river as it is, it causes water pollution and contaminates the surrounding environment, becoming a serious environmental problem.

[0003] In addition, the amount of food waste generated from homes and restaurants is gradually increasing. However, food waste contains a large amount of moisture and nutrients, so it is prone to spoilage and produces a bad smell.

[0004] In the past, organic waste, including livestock waste and food waste, was collected, fermented, and turned into fertilizer, thereby preventing waste of resources and environmental pollution. At the same time, since fertilizer made from organic waste, rather than chemical fertilizers, was used, it was possible to improve soil that was becoming acidic due to chemical fertilizers.

[0005] However, the method of fermenting organic waste to make fertilizer requires that the fertilizer be sufficiently fermented before it can be used on the soil, so it takes a long time to meet the fertilizer conditions, and as organic waste gradually increases, the oversupply of organic waste leads to a lack of composting capacity, making it difficult to dispose of organic waste, and even if composting capacity is strengthened and all organic waste is composted, the problem of composted fertilizer being thrown away due to the small amount of land to use the fertilizer compared to the increasing fertilizer production could not be solved.

[0006] Recently, attempts have been made to minimize environmental pollution by mixing organic waste with microorganisms and composting or decomposing them through an aerobic fermentation process. However, there are still unresolved issues with the emission of harmful gases and foul odors generated during the fermentation process.

[0007] To solve these problems, separate chemical treatments are used to purify harmful gases or reduce odors, but it is difficult to completely remove odors, and even if they are removed, the problem arises that they can cause further environmental pollution because they contain chemical elements.

[0008] Therefore, there is a need for technology that can solve the problems of harmful gases and odors in the atmosphere that may arise when processing the continuously increasing amount of organic waste in an environmentally friendly manner.

[0009] The present invention has been devised to solve the above-described problems, and the purpose of the present invention is to provide a deodorizing device for an organic waste treatment device capable of removing an unpleasant odor generated during the treatment of organic waste by utilizing microorganisms to deodorize the gas generated when treating organic waste using microorganisms before discharging the gas to the atmosphere.

[0032] FIG. 2 is a side cross-sectional view of a deodorizing device for an organic waste treatment device according to one embodiment of the present invention.

[0033] The terms used in the present invention are selected from the most widely used general terms as much as possible, but in certain cases, there are terms arbitrarily selected by the applicant. In such cases, the meaning of the terms should be understood by considering the meaning described or used in the detailed description of the invention, rather than the simple name of the term.

[0034] Hereinafter, the technical configuration of the present invention will be described in detail with reference to preferred embodiments illustrated in the attached drawings.

[0035] However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Like reference numbers designate like elements throughout the specification.

[0036] FIG. 1 is a drawing for explaining a deodorizing device for an organic waste treatment device according to one embodiment of the present invention, and FIG. 2 is a side cross-sectional view of a deodorizing device for an organic waste treatment device according to one embodiment of the present invention.

[0037] Referring to FIGS. 1 and 2, a deodorizing device (100) for an organic waste treatment device according to one embodiment of the present invention is a deodorizing device for removing odor and carbon dioxide before exhausting water vapor generated when hydrolyzing organic waste from a device that treats organic waste using microorganisms to the outside atmosphere.

[0038] Here, the organic waste refers to livestock waste including livestock manure and livestock carcasses, agricultural waste generated in agriculture, and various food waste generated in households or restaurants.

[0039] Meanwhile, in the present invention, the organic waste is connected to a device that generates steam when hydrolyzing the organic waste using the microorganisms to remove the odor and carbon dioxide contained in the steam, but this is not limited thereto, and the organic waste may be treated by connecting to a device that generates a gas such as gas or steam to remove the odor and carbon dioxide contained in the gas before exhausting the gas.

[0040] In addition, the deodorizing device (100) for the organic waste treatment device of the present invention is a deodorizing device that removes the odor contained in the steam by spraying microorganisms used in hydrolysis into the steam to remove the odor contained in the steam.

[0041] In detail, the deodorizing device (100) for an organic waste treatment device of the present invention is a deodorizing device that is connected to an organic waste treatment device (10) that hydrolyzes the organic waste using the microorganisms, performs a deodorizing operation to remove odor by spraying microorganisms on the water vapor generated when the organic waste is hydrolyzed in the organic waste treatment device (10), and then exhausts the deodorized water vapor into the atmosphere.

[0042] Here, the organic waste treatment device (10) is a device that destroys the organic waste and discharges only water vapor by hydrolyzing the organic waste using the microorganisms, and is composed of a reaction vessel (11), a stirring unit (12), an air supply unit (13), a discharge unit (14), a condensation unit (15), and an exhaust pipe (16).

[0043] The above reaction vessel (11) forms a space in which the organic waste and microbial carrier are accommodated and hydrolysis takes place. In the present invention, it is preferable to form it in a cylindrical shape for stirring the accommodated contents, but it may also be formed in various shapes depending on the user's design purpose.

[0044] Here, the microbial carrier is composed of a culture solution, sawdust, and bamboo pieces inoculated with Bacillus subtilis YBK-1 (KCTC 15303BP) strain in the culture medium and cultured in liquid for 48 hours at an internal temperature of 50°C in the culture medium.

[0045] The above bamboo pieces are preferably formed into a size of 5 to 10 cm in width and 10 to 15 cm in length to help with stirring and secure a gap when stirring the organic waste and the microbial carrier in the reaction vessel (11).

[0046] The above stirring unit (12) is provided inside the reaction vessel (11) and is a means for stirring the contents accommodated inside the reaction vessel (11). Specifically, a rotation axis is provided along the central axis of the reaction vessel, and a plurality of stirring blades are provided in a direction perpendicular to the rotation axis, and as the rotation axis rotates by the power of the motor, the plurality of stirring blades rotate to stir the contents accommodated inside the reaction vessel (11).

[0047] The above air supply unit (13) is a means for supplying external air or oxygen into the interior of the reaction vessel (11), thereby enabling microorganisms contained in the contents accommodated inside the reaction vessel (11) to smoothly discharge hydrolytic enzymes, thereby effectively destroying the organic waste.

[0048] The above discharge unit (14) is a means for discharging residues and gases generated by hydrolyzing the organic waste using the microorganisms to the outside of the reaction vessel (11). In the case of the gas, it is separated into vapor and water vapor, and only the water vapor is discharged to the outside.

[0049] The above condensing unit (15) is a means for condensing the water vapor discharged from the discharge unit (14) and changing its state into water. Specifically, about 70% of the water vapor discharged from the discharge unit (14) is discharged by changing its state into water, and the remaining about 30% is discharged in a water vapor state.

[0050] The above exhaust pipe (16) exhausts the remaining water vapor that is not condensed in the condenser (15) from the reaction vessel (11).

[0051] That is, the deodorizing device (100) for the organic waste treatment device of the present invention is a deodorizing device that is connected to the exhaust pipe (16) of the organic waste treatment device (10), into which steam exhausted from the exhaust pipe (16) flows in, and injects microorganisms into the introduced steam to remove odor and carbon dioxide contained in the steam.

[0052] In addition, the deodorizing device (100) comprises a main body (110), an intake fan (120), and a microbial spray unit (130).

[0053] The above body (110) has a long cylindrical shape with a central axis perpendicular to the ground, and provides a path for steam flowing in from the exhaust pipe (16) of the organic waste treatment device (10) to be exhausted upwards so that the steam is deodorized and exhausted into the atmosphere, and an internal space is formed in which a means for deodorizing the steam can be accommodated.

[0054] Meanwhile, in the present invention, as illustrated in FIG. 2, the main body (110) is depicted as a long cylindrical shape with a central axis perpendicular to the ground, but is not limited thereto, and may be formed in various shapes capable of providing a path for the water vapor to deodorize the water vapor and exhaust it into the atmosphere.

[0055] In addition, the main body (110) is connected to the exhaust pipe (16) of the organic waste treatment device (10) on the lower side, and an inlet (111) is formed at the upper end through which steam discharged from the exhaust pipe (16) flows in, and an exhaust port (112) is formed at the upper end through which the deodorized steam is discharged into the atmosphere.

[0056] Accordingly, the water vapor flowing in from the lower part of the main body (110) moves upward and is deodorized, and the deodorized water vapor is exhausted into the atmosphere through the exhaust port (112) formed at the upper part.

[0057] Here, the exhaust port (112) is formed in a structure that can be opened and closed.

[0058] Meanwhile, the deodorizing device (100) of the present invention may further be provided with a control unit for controlling the operation of each component.

[0059] Accordingly, the control unit can control the opening and closing of the exhaust port (112), and more specifically, the control unit can control the closing of the exhaust port (112) to block the steam from being exhausted into the atmosphere or the opening of the exhaust port (112) to allow the steam to be exhausted into the atmosphere.

[0060] The above-mentioned intake fan (120) is formed in the exhaust port (112) of the main body (110) and rotates the fan so that the steam flowing into the inlet port (111) formed in the lower part of the main body (110) is exhausted to the exhaust port (112) formed in the upper part of the main body (110), thereby sucking the steam upwards of the main body (110).

[0061] Here, the control unit can control the rotation speed of the intake fan (120) to control the speed at which the steam flowing into the inlet (111) moves to the upper exhaust port (112) and the amount of the steam.

[0062] The above microbial spray unit (130) is provided inside the main body (110) and sprays the microorganisms onto the steam while the steam moves from the inlet (111) to the exhaust port (112), thereby removing the odor contained in the steam.

[0063] Here, the microorganism spray unit (130) uses the same microorganism as the microorganism used in the organic waste treatment as the microorganism sprayed into the water vapor, and the microorganism is Bacillus subtilis YBK-1 (KCTC 15303BP) strain.

[0064] Additionally, the above-mentioned foul odor refers to ammonia contained in the water vapor.

[0065] In detail, the microorganism injection unit (130) is positioned on the path of rising steam inside the main body (110) to inject microorganisms into the moving steam, and the injected microorganisms react with ammonia contained in the steam to remove the ammonia contained in the steam.

[0066] Meanwhile, the above-mentioned microbial spray unit (130) is configured as a single stage and can remove ammonia through a single microbial shower of the water vapor, but as shown in FIG. 2 of the present invention, it is configured as a plurality of stages and can spray microorganisms several times on the rising water vapor to improve the ammonia removal rate contained in the water vapor.

[0067] For example, as illustrated in FIG. 2, the microbial injection unit (130) is sequentially composed of a first microbial injection unit (131), a second microbial injection unit (132), and a third microbial injection unit (133) from the inlet (111) to the exhaust port (112), and can apply a microbial shower three times to the rising steam.

[0068] At this time, when the microbial injection unit (130) is composed of multiple stages, multiple microbial injection units (130) are arranged at a predetermined distance along the central axis of the main body (110).

[0069] Meanwhile, the present invention may further include a carbon dioxide removal unit (140) for removing carbon dioxide contained in the water vapor.

[0070] The above carbon dioxide removal unit (140) is a collection plate made of zeolite material, and is placed between the microbial injection unit (130) and the exhaust port (112) inside the main body (110), so that the water vapor from which the ammonia has been removed passes through the microbial injection unit (130) and captures and removes the carbon dioxide contained in the water vapor while passing through the collection plate.

[0071] In addition, in the present invention, the carbon dioxide removal unit (140) is arranged between the microbial injection unit (130) and the exhaust port (112), but it may be arranged between the microbial injection units (130) configured in multiple stages or between the microbial injection units (130) and the inlet port (111) to capture and remove the carbon dioxide contained in the water vapor.

[0072] Meanwhile, the carbon dioxide removal unit (140) has a problem in that the collecting plate made of the zeolite material can easily become wet with moisture as the steam from the microbial shower passes through the microbial spray unit (130). If the collecting plate becomes wet, the efficiency of collecting the carbon dioxide from the steam may decrease.

[0073] Accordingly, the deodorizing device (100) of the present invention may further include a tube heater (150) at the bottom of the carbon dioxide removal unit (140), i.e., in the direction in which the microbial shower vapor flows in, in order to dry the collection plate of the carbon dioxide removal unit (140).

[0074] In addition, the deodorizing device (100) of the present invention may further include an activated carbon plate (160) made of carbon in order to remove ammonia contained in the water vapor in addition to the microbial spray unit (130).

[0075] In the present invention, the activated carbon plate (160) is placed between the microbial injection unit (130) and the carbon dioxide removal unit (140) as illustrated in FIG. 2, but the activated carbon plate (160) may be placed at various locations inside the main body (110).

[0076] In addition, the activated carbon plate (160) may become wet due to moisture contained in the water vapor as the water vapor passes through it. In this case, the wet activated carbon plate (160) has poor ammonia removal performance, so a tube heater (150) may be additionally provided below the activated carbon plate (160) as in the carbon dioxide removal unit (140).

[0077] Meanwhile, the deodorizing device (100) of the present invention is connected to the organic waste treatment device (10) by a connecting pipe (20), and more specifically, the exhaust pipe (16) of the organic waste treatment device (10) and the inlet (111) of the deodorizing device (100) are connected to each other by the connecting pipe (20).

[0078] Accordingly, water vapor discharged from the exhaust pipe (16) flows into the inlet (111) of the deodorizing device (100) through the connecting pipe (20).

[0079] At this time, the length and shape of the connecting pipe (20) may vary depending on the arrangement of the deodorizing device (100) and the organic waste treatment device (10).

[0080] In addition, the connecting pipe (20) has a valve formed at the end on the exhaust pipe (16) side, and when the water vapor flows into the connecting pipe (20) and hits the valve, some of the water vapor changes into water and is discharged to the outside together with the water condensed in the condensing unit (160), and the water vapor that has passed through the valve flows into the deodorizing device (100) through the inlet (111).

[0081] In addition, the present invention may further include a sensor capable of measuring the ammonia concentration and the carbon dioxide concentration in the exhaust port (112).

[0082] Accordingly, when the ammonia concentration and the carbon dioxide concentration in the sensor are higher than the reference value set by the user, the control unit can close the exhaust port (112) to prevent the water vapor from being exhausted into the atmosphere.

[0083] At this time, the control unit can control the operation of the intake fan (120) to stop.

[0084] That is, if the ammonia concentration and carbon dioxide concentration in the sensor are below the reference value set by the user, the exhaust port (112) is opened to allow the water vapor to be exhausted into the atmosphere.

[0085] Here, the user-preset reference values ​​are set to the minimum concentrations at which the ammonia concentration and the carbon dioxide concentration can cause air pollution, and when the reference values ​​are exceeded, it is determined that air pollution can be caused, and thus the exhaust port (112) is closed, thereby blocking the water vapor from being discharged into the atmosphere.

[0086] Therefore, the deodorizing device (100) for an organic waste treatment device of the present invention can remove ammonia, etc., which is the cause of the odor contained in the water vapor, by spraying the microorganisms into the water vapor generated when treating the organic waste using the microorganisms, thereby enabling deodorization in an environmentally friendly manner rather than chemical treatment, and has the advantage of preventing air pollution that may occur when the water vapor containing the carbon dioxide is discharged into the atmosphere by capturing the carbon dioxide contained in the water vapor through a capturing plate made of the zeolite.

[0087] As described above, the present invention has been illustrated and described with reference to preferred embodiments, but is not limited to the above embodiments, and various changes and modifications may be made by a person skilled in the art to which the invention pertains within a scope that does not depart from the spirit of the present invention.
