Description

Technology Field

[0001] The present invention relates to an air pollution prevention device for preventing dust and odors from being released into the atmosphere during the process of high-speed fermentation and drying of livestock manure. Background Technology

[0002] Livestock farms generate livestock manure, and high-speed fermentation and drying equipment is installed to process it.

[0003] The livestock manure high-speed fermentation and drying device induces fermentation and drying by introducing livestock manure and organic inputs into a fermentation tank, stirring them, and injecting high-temperature air to activate the microorganisms in the inputs.

[0004] The input remains in the fermentation tank as the fermentation process proceeds; as fermentation progresses, its volume and weight decrease, and an amount of water vapor and gas equivalent to this decrease is generated and discharged, while a portion of the solid components of the input becomes dust. In the following description, 'water vapor,' 'gas,' and 'dust' will be abbreviated as 'fluid.'

[0005] An exhaust duct is connected to the upper part of the fermentation tank, and the other end of the exhaust duct is connected to an odor reduction device.

[0006] The exhaust duct allows the fluid to be transferred from the fermentation tank to the odor reduction device.

[0007] The odor reduction device captures water vapor and dust to ultimately release clean air into the atmosphere.

[0008] Odor reduction devices are equipped with piping through which fluid passes. Dust in the fluid accumulates or adheres to the pipes, leading to the problem of clogging over time.

[0009] If the piping in the odor reduction device becomes clogged, there is a problem where the discharge rate of water vapor slows down, and if dust is released without being removed from the device, there is a problem of air pollution. Prior art literature

The presented embodiments are examples to aid in understanding the present invention, and may be implemented with various modifications different from the presented embodiments without departing from the technical spirit or essential features of the present invention.

These terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component.

[0030] The definitions of terms used in this specification may vary depending on the context and must be determined by referring to the entire content of the specification.

[0031] Throughout the specification, the same reference numerals refer to the same components.

[0032] First, an air pollution prevention device using high-speed fermentation drying of livestock manure according to an embodiment of the present invention will be described with reference to FIGS. 1 through 3. FIG. 1 is a drawing for describing an air pollution prevention device using high-speed fermentation drying of livestock manure according to an embodiment of the present invention. FIG. 2 is a cross-sectional view for describing the configuration of a common duct in an air pollution prevention device using high-speed fermentation drying of livestock manure according to an embodiment of the present invention. FIG. 3 is a drawing for describing an odor reduction device in an air pollution prevention device using high-speed fermentation drying of livestock manure according to an embodiment of the present invention.

[0033] An air pollution prevention device through high-speed fermentation and drying of livestock manure according to an embodiment of the present invention is,

[0034] It can be configured to include a fermentation tank (10), a plurality of hoppers (20), a common duct (30), a main duct (40), and an odor reduction device (50).

[0035] The fermentation tank (10) is fed with livestock manure and organic materials and stirred, and hot air is injected to induce even fermentation and drying of the materials.

[0036] The input remains in the fermentation tank (10) and the fermentation process proceeds. As fermentation progresses, the volume and weight decrease, and steam and gas are generated and discharged in proportion to the decrease, and some of the solid components of the input become dust. In the following description, 'steam', 'gas', and 'dust' are abbreviated as 'fluid'.

[0037] The description of the fermentation tank (10) is detailed in Patent Documents 1 and 2, so a detailed description is omitted.

[0038] A plurality of hoppers (20) are installed at the top of the fermentation tank (10) to induce the movement of fluids (steam, gas, and dust) generated from the fermentation tank (10).

[0039] The hopper (20) can be provided in a shape that is wide at the bottom and narrow at the top, and due to this shape, the fluid flow rate increases as the fluid flow rate rises.

[0040] A common duct (30) is positioned above the plurality of hoppers (20). More specifically, it is a configuration in which multiple hoppers (20) are combined in a single common duct (30).

[0041] When viewed from a position crossing the upper part (22) of the hopper (20), the cross-sectional area of ​​the common duct (30) is formed to be wider than the cross-sectional area of ​​the plurality of hoppers (20).

[0042] When the cross-sectional area of ​​a pipe through which fluid flows increases rapidly, a phenomenon occurs in which the flow velocity decreases rapidly.

[0043] That is, the fluid has a fast flow rate when passing through the hopper (20), and immediately after passing through the upper part (22) of the hopper, the flow rate is rapidly reduced as it is exposed to a wide space inside the common duct (30).

[0044] As the fluid flow rate slows down rapidly, some of the dust contained in the fluid settles and accumulates on the bottom (32) of the common duct (30).

[0045] That is, the fluid discharged from the common duct (30) has a significant amount of dust removed.

[0046] One end of the main duct (40) is connected to the common duct (30) and the other end is connected to the odor reduction device (50). The main duct (40) directs fluid from the main duct (40) to the odor reduction device (50).

[0047] The air pollution prevention device through high-speed fermentation drying of livestock manure according to the embodiment of the present invention as described above can remove some of the dust in advance inside the common duct (30), thereby significantly reducing the problem of various pipes constituting the odor reduction device (50) becoming clogged or narrowed.

[0048] In particular, by improving the blockage or narrowing of various pipes, it is possible to prevent the fluid flow rate from slowing down, and by facilitating the flow of steam and gas, the fluid in the odor reduction device (50) can come into sufficient contact with water, thereby more effectively removing air pollutants and preventing air pollution.

[0049] Referring to FIG. 2, the common duct (30) is formed with a slope such that the bottom of the common duct (32) is inclined to one side, and a first drain valve (34) can be installed on the inclined lower side. The first drain valve (34) can be connected to a wastewater purification tank (530) through piping.

[0050] In addition, the common duct (30) may be equipped with an inspection port (36) as shown in FIG. 1. When the inspection port (36) is opened, a worker can access the interior of the common duct (30).

[0051] A worker can access the inside of the common duct (30) through the inspection port (36) and clean it with water, thereby keeping the inside of the common duct (30) clean.

[0052] Inside the common duct (30), water vapor may condense to form condensate water, and water may accumulate while a worker cleans with water. In this case, the first drain valve (34) can be opened to flush the accumulated water into the wastewater purification tank (530).

[0053] Additionally, the upper part of the hopper (22) can be positioned higher than the common duct bottom (32) as shown in FIG. 2 (see h).

[0054] As explained above, when a worker cleans the inside of the common duct (30) with water, the backflow of water sprayed towards the fermentation tank (10) can be suppressed as much as possible.

[0055] Additionally, referring to FIG. 1, a cleaning door (42) may be installed in the main duct (40) at a position lower than the part where the main duct (40) is connected to the odor reduction device (50).

[0056] As the fluid moves along the main duct (40), some of the dust may accumulate in one place of the main duct (40) due to the influence of gravity.

[0057] Additionally, a portion of the main duct (40) may be arranged in a vertical or inclined direction, and a tee fitting (46) may be installed in the middle of the main duct (40).

[0058] One side of the above tee fitting (46) is piped so that the above odor reduction device (50) is connected.

[0059] The cleaning door (42) can be installed in the main duct (40) at a position lower than the tee fitting (46).

[0060] Thus, while the fluid travels along the main duct (40), some of the dust may accumulate on the top of the cleaning door (42), and the worker can open the cleaning door (42) to remove the accumulated dust.

[0061] Additionally, a second drain valve (44) may be installed in the main duct (40) at a position lower than the tee fitting (46) and higher than the position of the cleaning door (42). The second drain valve (44) may be connected to a wastewater purification tank (530) through piping.

[0062] Thus, as the fluid moves along the main duct (40), some of the water vapor may condense to produce condensed water, and the condensed water may accumulate above the cleaning door (42), and the operator can open the second drain valve (44) to flush the accumulated condensed water into the wastewater purification tank (530).

[0063] Meanwhile, referring to FIG. 1, a dust bin (510) can be installed at the bottom of the cleaning door (42).

[0064] When a worker opens the cleaning door (42), dust or condensed water is poured directly into the dust bin (510), thereby preventing the surrounding area from being contaminated.

[0065] The above odor reduction device (50) is described in detail with reference to FIG. 3.

[0066] Referring to FIG. 3, the odor reduction device (50) may be configured to include first and second scrubbers (100, 200), a water tank (300), and first and second circulation pumps (330, 340).

[0067] The first scrubber (100) allows fluid to flow in from the main duct (40), sprays water onto the fluid flowing in from the main duct (40), and causes the flowing fluid to rise and be discharged.

[0068] The first scrubber (100) is provided in the form of a large tank standing vertically, and a first inlet (110) is formed at an intermediate height, and the main duct (40) is connected to the first inlet (110). A first outlet (120) is formed at the top of the first scrubber (100).

[0069] Additionally, a plurality of nozzles may be installed inside the first scrubber (100), and for example, referring to FIG. 3, a first spray nozzle (332) and a second spray nozzle (334) may be installed.

[0070] The plurality of nozzles are positioned higher than the first inlet (110).

[0071] Thus, when water is sprayed from the first spray nozzle (332) or the second spray nozzle (334), the water comes into contact with the fluid introduced through the first inlet (110), and thus dust or harmful substances contained in the fluid meet with the sprayed water and descend, accumulating on the inner bottom of the first scrubber (100).

[0072] The second scrubber (200) allows fluid to flow in from the first scrubber (100), sprays water onto the fluid flowing in from the first scrubber (100), and causes the fluid to rise and be discharged.

[0073] The second scrubber (200) is provided in the form of a large tank standing vertically, and a second inlet (210) is formed at an intermediate height, and the first outlet (120) and the second inlet (210) are connected by a blower duct (130).

[0074] A second outlet (220) is formed at the top of the second scrubber (200).

[0075] Additionally, multiple nozzles may be installed inside the second scrubber (200) or a single nozzle, and, for example, referring to FIG. 3, a third injection nozzle (342) may be installed in a single nozzle.

[0076] The third injection nozzle (342) is positioned higher than the second inlet (210).

[0077] Thus, when water is sprayed from the third spray nozzle (342), the water comes into contact with the fluid introduced through the second inlet (210), and thus dust or harmful substances contained in the fluid meet with the sprayed water and descend, accumulating on the inner bottom of the second scrubber (200).

[0078] In particular, the fluid is introduced into the second scrubber (200) in a state where the contaminants have been purified in the first scrubber (100) and secondary purification is performed, so the effect of purifying it even more cleanly can be expected.

[0079] The water tank (300) can store water overflowing from the first scrubber (100) or the second scrubber (200), and a worker can fill it with clean water in advance.

[0080] Referring to FIG. 3, the first drain line (310) can be connected from the first scrubber (100) to the water tank (300), and wastewater can be filled up to the inlet of the first drain line (310).

[0081] Additionally, the second drain line (320) can be connected from the second scrubber (200) to the water tank (300), and wastewater can rise up to the inlet of the second drain line (320).

[0082] Referring to FIG. 3, the first circulation pump (330) supplies water to be sprayed from the water tank (300) to the first scrubber (100). The first circulation pump (330) supplies water to be sprayed through the first and second spray nozzles (332, 334).

[0083] Referring to FIG. 3, the second circulation pump (340) causes the water accumulated in the second scrubber (200) to be sprayed into the second scrubber (200). The second circulation pump (340) supplies water to be sprayed through the third spray nozzle (342).

[0084] That is, water is circulated and sprayed from the second scrubber (200) using the second circulation pump (340), and thereby the second scrubber (200) additionally removes pollutants, including dust that may be contained in the fluid, so that the gas released into the atmosphere is clean and has the effect of preventing air pollution.

[0085] Meanwhile, referring to FIG. 3, the first scrubber (100) and the second scrubber (200) are connected by a blower duct (130) to allow the fluid to move. The blower duct (130) connects the first outlet (120) of the first scrubber (100) and the second inlet (210) of the second scrubber (200). A blower (132) is installed in the blower duct (130).

[0086] That is, when the blower (132) is operated, the fluid can increase its flow velocity as it moves along the blower duct (130), thereby allowing the fluid to move quickly without stagnation.

[0087] On the other hand, referring to FIG. 3, a contamination level measuring port (400) may be installed on the upper part of the second scrubber (200). A contamination level measuring port (400) is installed on the upper part of the second outlet (220), and the contamination level of the fluid is measured through the contamination level measuring port (400) when the fluid is discharged through the second outlet (220).

[0088] Thus, when the pollution detection value measured by the pollution measurement device (400) does not reach the permissible emission setting value, it is notified to the manager or control center, thereby inducing the manager to inspect the equipment and contributing to the prevention of air pollution.

[0089] An exhaust port (410) is placed at the top of the second outlet (220) to prevent rainwater from flowing into the second scrubber (200).

[0090] On the other hand, referring to FIG. 3, a first butterfly valve (521) may be installed at the bottom of the first scrubber (100), a second butterfly valve (522) may be installed at the bottom of the second scrubber (200), and a third butterfly valve (523) may be installed at the bottom of the water tank (300).

[0091] Additionally, a wastewater purification tank (530) may be placed at the bottom of the odor reduction device (50). The wastewater purification tank (530) may be placed at the bottom of the first and second scrubbers (100, 200) and the water tank (300).

[0092] Thus, when any one of the first, second, and third butterfly valves (521, 522, 523) is opened, wastewater is poured out and the wastewater can be stored in the wastewater purification tank (530).

[0093] The wastewater purification tank (530) can be transferred to a separate treatment device and discharged or reused after being purified.

[0094] Embodiments of the present invention have been described above with reference to the accompanying drawings. However, those skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
