Description

Porous high-performance biochar manufacturing device

[0001] The present invention relates to a porous high-performance biochar manufacturing device, and more specifically, to a porous high-performance biochar manufacturing device that can not only rapidly and effectively convert large amounts of livestock manure into resources in an environmentally friendly manner, but also fundamentally prevent bad odors around farms and prevent environmental pollution by condensing and fermenting wastewater and converting it into distilled water.

[0002] As demand for livestock products soared, the mass-production of livestock products like cattle, pigs, and chickens became commonplace. However, the disposal of the large volumes of manure generated during livestock farming has become a problem. Livestock farms are becoming a source of significant stress for nearby residents, with the resulting stench and soil and groundwater contamination.

[0003] Most livestock manure is disposed of through composting facilities (83.1%), liquid fertilizer facilities (6.6%), purification facilities (4.7%), and outsourced treatment (5.6%). Inappropriate livestock manure disposal by some livestock farms due to insufficient moisture control materials and inadequate management techniques is recognized as a major culprit in environmental problems. Therefore, as the number of livestock increases, improper livestock manure disposal can lead to environmental pollution and the potential for the spread of infectious diseases such as pathogens.

[0004] Conventional biological treatment processes for livestock waste mainly utilize anaerobic, aerobic, and facultative microorganisms. In the case of aerobic treatment of livestock waste, it is generally operated using a batch-type SBR (semi-batch reactor) or an AO (anoxic and oxic) method that uses an aerobic tank and an anoxic tank. However, as the concentration of incoming manure, such as fattening sheds, increases, the treatment efficiency of livestock waste and the neutralization treatment ability of microorganisms decrease significantly, and as a result, the operating rate of blowers increases, which reduces the durability of many blowers and air diffusers, causing an increase in electricity costs. In particular, there is a problem of generating a strong foul odor.

[0005] The present invention has been devised to solve the above problems, and the purpose of the present invention is to provide a porous, high-performance biochar manufacturing device that can not only quickly and effectively convert large amounts of livestock waste into resources in an environmentally friendly manner, but also fundamentally prevent odors around farms, prevent environmental pollution by converting wastewater into distilled water by condensing and fermenting it, and fundamentally block the generation of odors by feeding back and then incinerating odorous gases generated during the carbonization process.

[0006] Another object of the present invention is to provide a porous, high-performance biochar manufacturing device that prevents the leakage of odorous gas during the carbonization process by the completely sealed structure of the carbonization equipment, the feeding conveying screw is manufactured as a special wear shoe type screw to effectively prevent the backflow phenomenon, and a shutter is installed to prevent the backflow of water vapor and gas.

[0007] Another object of the present invention is to provide a porous, high-performance biochar manufacturing device having a rotary kiln-type heat storage structure for a carbonization furnace, which has an excellent energy-saving effect due to a continuous heat retention effect after heating once, and which prevents a decrease in thermal conductivity due to a phenomenon (coking phenomenon) in which foreign substances such as carbohydrates or proteins of livestock manure adhere to the inside of the carbonization furnace and make it dirty, thereby reducing heat transfer efficiency, by cleaning the inside of the carbonization furnace, and by preventing the coking phenomenon inside the carbonization furnace to maximize thermal conductivity, and which has an automatic carbonized material discharge function after complete carbonization and drying.

[0008] Another object of the present invention is to provide a porous high-performance biochar manufacturing device capable of preventing steam and gas within a carbonization facility from leaking to the outside and preventing coking, in which residual waste within a carbonization furnace adheres to the inner surface of the carbonization furnace.

[0009] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0010] In order to solve the above problem, a porous high-performance biochar manufacturing device according to an embodiment of the present invention includes a livestock manure supply facility that supplies and transports a large amount of livestock manure containing moisture; and a carbonization facility that, when livestock manure is supplied from the livestock manure supply facility, creates an oxygen-blocking atmosphere inside the facility and then heats the facility to a certain temperature to carbonize the livestock manure; wherein the livestock manure supply facility automatically opens and closes an outlet depending on whether the livestock manure is discharged, and is configured to seal a connection portion between the livestock manure supply facility and the carbonization facility.

[0011] The above-mentioned livestock manure supply facility may include: a supply hopper for supplying livestock manure; a supply transfer screw for generating a rotational force to transfer the livestock manure supplied from the supply hopper in one direction; an input transfer screw installed at the entrance side of the carbonization facility, a portion of which is inserted into the interior of the carbonization facility and the other portion is disposed outside the carbonization facility, and for generating a rotational force to supply the livestock manure supplied inside into the interior of the carbonization facility; and an input hopper for being disposed between the supply transfer screw and the input transfer screw and for feeding the livestock manure transferred through the supply transfer screw into the input transfer screw.

[0012] The above carbonization facility may include a rotary kiln-type carbonization furnace having spiral blades arranged on the inner surface along the axial direction; a heating furnace configured to surround the outer side of the carbonization furnace to heat the carbonization furnace in a heat storage manner; a heating burner for heating the heating furnace; and a waste gas treatment device connected to the heating furnace to capture and purify waste gas generated from the heating furnace.

[0013] The above-mentioned manure supply facility further includes a shutter that is rotatably coupled to one end of the input conveying screw inserted into the interior of the carbonization facility and automatically opens and closes one end of the input conveying screw depending on whether the manure is discharged; the shutter can open one end of the input conveying screw by rotating outward when the manure is discharged from the input conveying screw due to pressure on the manure, and close one end of the input conveying screw by rotating inward due to its own weight when the discharge of the manure from the input conveying screw stops.

[0014] The above-mentioned manure supply facility may further include a packing assembly disposed between a flange pipe disposed at the inlet side of the carbonization furnace and the feeding conveying screw inserted into the interior of the flange pipe, thereby sealing the space between the flange pipe and the feeding conveying screw.

[0015] The above packing assembly may include a packing member that is press-fitted between the outer surface of the input conveying screw and the inner surface of the flange tube; a packing pressurizing member that is coupled to the flange tube and contacts one surface of the packing member to pressurize the packing member in the axial direction of the flange tube; and a stopper that is fixed to the inner surface of the flange tube, is arranged opposite to the packing pressurizing member along the axial direction of the flange tube with the packing member as the center, and supports the packing member that is pressed by the packing pressurizing member.

[0016] The above carbonization equipment further includes a scraper which is arranged inside the carbonization furnace and is connected to the outer surface of the feeding screw inserted into the inside of the carbonization furnace and comes into contact with the inner surface of the carbonization furnace, and the scraper can prevent the coal dust from sticking to the inner surface of the carbonization furnace by scraping the inner surface of the carbonization furnace when the carbonization furnace rotates, thereby stirring the coal dust and preventing the coal dust from clumping together.

[0017] The above scraper may be configured to scrape the inner surface of the carbonization furnace in a section of the carbonization furnace in which the input conveying screw is received.

[0018] The scraper may include a support frame that is coupled to and supported by the outer surface of the feed screw; and a plurality of scraping members that are arranged in a plurality on the support frame along the axial direction of the carbonization furnace and contact the inner surface of the carbonization furnace, and that scrape the inner surface of the carbonization furnace while stirring the shaft powder when the carbonization furnace rotates.

[0019] The above plurality of scraping members can be arranged to be inclined at a preset angle with respect to the support frame.

[0020] The above plurality of scraping members may each include a spiral coil portion coupled to the support frame; and a scraping portion elastically supported by the spiral coil portion and in contact with the inner surface of the carbonization furnace to scrape the inner surface of the carbonization furnace.

[0021] The above carbonization equipment may further include a scratching roller that is accommodated inside the carbonization furnace and rotates inside the carbonization furnace together with the carbonization furnace when the carbonization furnace is rotated, thereby crushing the carbonization furnace and scraping the inner surface of the carbonization furnace.

[0022] The above scratching roller may include a cylindrical roller body; and a plurality of scratching pins arranged in a plurality around the roller body along the axial direction of the roller body, and scraping the inner surface of the carbonization furnace while crushing the shaft powder.

[0023] The method may further include a sludge transfer screw for separating and transferring sludge of solids from carbonized matter discharged from the carbonization facility; a fermentation facility for fermenting the sludge transferred by the sludge transfer screw; a pellet forming facility for pelletizing the sludge fermented in the fermentation facility; a gas-liquid separation facility for separating odorous gas and water vapor from the carbide discharged from the carbonization facility; a cooling condensation facility for re-cooling and condensing the water vapor separated in the gas-liquid separation facility and storing the condensate; and a wastewater fermentation tank for removing odor remaining in the condensate condensed in the cooling condensation facility.

[0024] According to an embodiment of the present invention, not only can a large amount of livestock waste be quickly and effectively recycled in an environmentally friendly manner, but also bad odors around the farm can be fundamentally prevented, and environmental pollution can be effectively prevented by condensing and fermenting wastewater to convert it into distilled water.

[0025] In addition, high-moisture content (approximately 78% or more) manure can be fermented to low-moisture content (10% or less) to produce large quantities of fermented manure compost, maximizing profits.

[0026] In addition, the completely sealed structure of the carbonization facility prevents the leakage of odorous gases during the carbonization process, and the odorous gases generated during the carbonization process are fed back and then incinerated, thereby fundamentally blocking the generation of odors.

[0027] In addition, the input conveying screw is manufactured as a special wear shoe type screw to effectively prevent backflow, and a shutter is installed to prevent backflow of steam and gas.

[0028] In addition, it is composed of a rotating kiln-type storage structure for carbonization, so it has an excellent energy-saving effect due to the continuous heat retention effect after heating once.

[0029] In addition, the inclined spiral blades inside the carbonizer enable efficient movement and uniform stirring of the pellets, thereby producing uniform pellet products during subsequent pellet processing.

[0030] In addition, in order to prevent a decrease in thermal conductivity due to a phenomenon (coking phenomenon) in which foreign substances such as carbohydrates or proteins in the manure adhere to the inside of the carbonizer and cause a mess, thereby reducing heat transfer efficiency, the inside of the carbonizer is cleaned, the inside of the carbonizer is prevented from coking, and the thermal conductivity is maximized. In addition, an automatic carbon discharge function is provided after complete carbonization and drying.

[0031] In addition, the manure supply facility automatically opens and closes the outlet depending on whether manure is discharged, and is configured to seal the connection between the manure supply facility and the carbonization facility, thereby preventing steam and gas inside the carbonization facility from flowing back into the manure supply facility, and also preventing steam and gas inside the carbonization facility from leaking to the outside through the connection between the manure supply facility and the carbonization facility.

[0032] In addition, since a scraper and a scratching roller are arranged inside the carbonization furnace to constantly scrape the inner surface of the carbonization furnace when the carbonization furnace rotates, the coking phenomenon in which the remaining stock in the carbonization furnace adheres to the inner surface of the carbonization furnace is prevented, and thus the decrease in thermal conductivity due to the coking phenomenon is prevented, thereby reducing the energy cost used for heating the carbonization furnace.

[0068] Referring to FIGS. 1 to 10, a porous high-performance biochar manufacturing device (100) according to an embodiment of the present invention (hereinafter referred to as “biochar manufacturing device (100)”) can quickly dry and carbonize about 10 to 20 tons of livestock manure generated on the same day.

[0069] The biochar manufacturing device (100) has a carbonization processing capacity set to approximately 1,800*5000 / 30㎥, an operating time set to 7 hours (carbonization) and 3-4 hours (drying), and a carbonization processing temperature set to approximately 400℃ / drying temperature set to approximately 150℃.

[0070] In addition, the biochar manufacturing device (100) can reuse LPG fuel and methane gas generated in the carbonization process.

[0071] Here, livestock manure includes both liquid and solid livestock manure (including manure residues separated and left over during cleaning in livestock houses, cleaning water, and feed residues spilled during eating).

[0072] The biochar manufacturing device (100) includes a livestock manure supply device (110) and a carbonization device (120).

[0073] The manure supply facility (110) supplies and transports a large amount of manure containing moisture (about 78% or more).

[0074] The manure supply facility (110) may include a supply hopper (111), a supply transfer screw (112), an input transfer screw (113), and an input hopper (114).

[0075] The supply hopper (111) stores manure and can supply manure using the supply transfer screw (112).

[0076] The supply transfer screw (112) generates rotational force to transfer the shaft powder supplied from the supply hopper (111) in one direction.

[0077] At this time, the supply transfer screw (112) may be configured to be operated by a motor (M) as an inclined screw.

[0078] The input conveying screw (113) is installed on the inlet side of the carbonization equipment (120) and can generate rotational force to supply the input shaft material into the interior of the carbonization equipment (120).

[0079] At this time, a part of the input transfer screw (113) may be inserted into the inside of the carbonization equipment (120), and another part of the input transfer screw (113) may be placed outside the carbonization equipment (120).

[0080] For example, the feed conveying screw (113) may include a screw pipe in which a portion is inserted into the interior of the carbonization facility (120) and the other portion is disposed outside the carbonization facility (120) and an input hopper (114) is coupled to the upper portion, a screw shaft disposed inside the screw pipe and generating a rotational force to transport the shaft material fed into the interior of the screw pipe in one direction and discharge it to the exterior of the screw pipe, and a shaft drive motor coupled to an end of the screw shaft to rotate the screw shaft.

[0081] The input hopper (114) is arranged between the supply transfer screw (112) and the input transfer screw (113), and the feed transferred through the supply transfer screw (112) can be fed into the input transfer screw (113).

[0082] When livestock manure is supplied from the livestock manure supply facility (110), the carbonization facility (120) creates an oxygen-blocking atmosphere inside and then heats the atmosphere to a certain temperature to carbonize the livestock manure.

[0083] That is, the carbonization facility (120) can homogeneously carbonize livestock manure in an oxygen-free state.

[0084] At this time, the carbonization facility (120) can carbonize the waste by heating it through a heat storage method.

[0085] The carbonization facility (120) may include a carbonization furnace (121), a heating furnace (122), a heating burner (123), and a waste gas treatment device (124).

[0086] The carbonization furnace (121) has spiral blades (120a) arranged on the inner surface along the axial direction, and can stir the shaft powder introduced into the interior by rotating it while transporting it in one direction.

[0087] Through this, efficient movement and uniform stirring of the manure are possible, thereby producing uniform pellet products during subsequent pellet processing.

[0088] The carbonization furnace (121) can be implemented in the form of a rotary kiln.

[0089] A rotating disc (127) may be placed on the exit side of the carbonization furnace (121).

[0090] At this time, a tooth (127a) is formed on the outer surface of the rotating disc (127), and the tooth (127a) can be configured to mesh (mesh) with the driving pinion (129a) of the rotating motor (129).

[0091] Accordingly, when the rotary motor (129) rotates, the rotary disc (127) rotates by the power, and the carbonization furnace (121) can rotate.

[0092] The carbonization furnace (121) can be configured to have a completely sealed structure and produce high-quality carbonized materials in an oxygen-free environment.

[0093] At this time, the odor generated during the carbonization process can be blocked from the source by sending the odor gas to the heating burner (123) of the carbonization facility (120) and incinerating it. Here, the odor includes ammonia, nitrogen dioxide, methane, etc.

[0094] A discharge transfer screw (128) can be installed on the outlet side of the carbonization furnace (121).

[0095] The discharge transfer screw (128) can transfer and discharge carbides discharged from the outlet side of the carbonization furnace (121) in one direction.

[0096] At this time, among the odorous gas and water vapor discharged from the outlet side of the discharge conveying screw (128), the water vapor is separated by the gas-liquid separation facility (160), and the odorous gas is sent (fed back) to the heating burner (123) of the carbonization facility (120) and can be incinerated.

[0097] The heating furnace (122) surrounds the outer surface of the carbonization furnace (121) and can heat the carbonization furnace (121).

[0098] That is, the carbonization furnace (121) and the heating furnace (122) are configured as a heat storage structure, so that they can have a continuous heat retention effect after heating once, thereby saving energy.

[0099] The heating burner (123) is placed at the bottom of the heating furnace (121) and can heat the heating furnace (121).

[0100] The waste gas treatment device (124) is connected to the heating furnace (122) at the upper side of the heating furnace (121) and can capture and purify waste gas generated from the heating furnace (121).

[0101] At this time, an exhaust gas pipe (121a), a plurality of wet scrubbers (121b) that filter the exhaust gas flowing into the exhaust gas pipe (121a), and a blower (121c) that discharges the gas purified by the wet scrubbers (121b) into the atmosphere may be arranged between the waste gas treatment device (124) and the heating furnace (121).

[0102] For example, a plurality of wet scrubbers (121b) can capture and remove fine particle dust contained in the exhaust gas by spraying water into the exhaust gas.

[0103] Meanwhile, referring to FIG. 11, the manure supply facility (110) is configured to automatically open and close the outlet depending on whether manure is discharged, and to seal the connection between the manure supply facility (110) and the carbonization facility (120).

[0104] Accordingly, it is possible to prevent steam and gas inside the carbonization facility (120) from flowing back into the livestock manure supply facility (110), and also to prevent steam and gas inside the carbonization facility (120) from leaking to the outside through the connection between the livestock manure supply facility (110) and the carbonization facility (120).

[0105] The manure supply facility (110) may further include a shutter (115).

[0106] The shutter (115) can be rotatably connected to one end of the feed conveying screw (113) inserted into the interior of the carbonization facility (120).

[0107] The shutter (115) can automatically open and close one end of the feed conveying screw (113) depending on whether or not the manure is discharged.

[0108] More specifically, the shutter (115) can open one end of the input transfer screw (113) by rotating outward when the shaft material is discharged from the input transfer screw (113) and by being pressurized by the shaft material, and can close one end of the input transfer screw (113) by rotating inward by its own weight when the shaft material is stopped being discharged from the input transfer screw (113).

[0109] For example, the shutter (115) may include a hinge pin coupled to the input transfer screw (113), a shutter body rotatably coupled to the hinge pin to open and close an end of the input transfer screw (113), and a heat-resistant and fire-resistant sealing member attached to the inner surface of the shutter body along the edge of the shutter body and contacting the input transfer screw (113) when the shutter body closes one end of the input transfer screw (113) to seal the space between the shutter body and the input transfer screw (113).

[0110] Referring to FIGS. 11 and 12, the feed supply device (110) may further include a packing assembly (116).

[0111] The packing assembly (116) is arranged between a flange pipe (121d) placed on the inlet side of the carbonization furnace (121) and an input transfer screw (113) inserted into the interior of the flange pipe (121d), thereby enabling an airtight seal between the flange pipe (121d) and the input transfer screw (113).

[0112] The packing assembly (116) may include a packing member (116a), a packing pressure member (116b), and a stopper (116c).

[0113] The packing member (116a) is press-fitted between the outer surface of the feed screw (113) and the inner surface of the flange pipe (121d) to seal the space between the outer surface of the feed screw (113) and the inner surface of the flange pipe (121d).

[0114] For example, the packing member (116a) can be formed of a graphite material having heat resistance and tension.

[0115] The packing pressure member (116b) is coupled to the flange pipe (121d) and can pressurize the packing member (116a) in the axial direction of the flange pipe (121d) by contacting one surface of the packing member (116a).

[0116] For example, the packing pressurizing member (116b) may include a pressurizing pipe including a pipe portion inserted into the interior of a flange pipe (121d) and in contact with one surface of the packing member (116a), a flange portion positioned at an end of the pipe portion and in contact with the end of the flange pipe (121d), and a fastening member that penetrates the flange portion of the pressurizing pipe and is fastened to the end of the flange pipe (121d) to pressurize the pressurizing pipe toward the packing member (116a). At this time, the fastening member may include a bolt and a nut.

[0117] The stopper (116c) can be positioned opposite the packing pressure member (116b) along the axial direction of the flange pipe (121d) with the packing member (116a) as the center.

[0118] The stopper (116c) is fixed to the inner surface of the flange pipe (121d) and can support the packing member (116a) that is pressed by the packing pressurizing member (116b).

[0119] Referring to FIG. 11, the carbonization facility (120) may further include a scraper (120b).

[0120] The scraper (120b) is coupled to the outer surface of the feed screw (113) inserted into the inside of the carbonization furnace (121) and is placed inside the carbonization furnace (121), and can be placed in contact with the inner surface of the carbonization furnace (121).

[0121] Accordingly, the scraper (120b) can prevent the powder from sticking to the inner surface of the carbonization furnace (121) by scraping the inner surface of the carbonization furnace (121) when the carbonization furnace (121) rotates, and can prevent the powder from clumping by stirring the powder.

[0122] At this time, the scraper (120b) can be configured to scrape the inner surface of the carbonization furnace (121) in a section of the carbonization furnace (121) in which the input transfer screw (113) is received.

[0123] Accordingly, the residual fuel remaining at the entrance of the carbonization furnace (121) is not attached to the inner wall of the carbonization furnace (121) and can be recovered back to the center of the carbonization furnace (121).

[0124] In addition, the scraper (120b) also performs the role of stirring the ash to prevent the ash from clumping together, thereby enabling heat to be transferred to the ash evenly.

[0125] Referring to FIGS. 12 and 13, the scraper (120b) may include a support frame (120b1) and a plurality of scraping members (120b2).

[0126] The support frame (120b1) can be supported by being joined to the outer surface of the input transfer screw (113).

[0127] For example, the support frame (120b1) may include a first frame portion that is coupled to the outer surface of the input transfer screw (113) and is arranged vertically with respect to the central axis of the input transfer screw (113), and a second frame portion that is coupled to an end of the first frame portion and is arranged parallel to the central axis of the input transfer screw (113) and on which a plurality of scraping members (120b2) are installed.

[0128] A plurality of scraping members (120b2) may be arranged in a plurality on the support frame (120b1) along the axial direction of the carbonization furnace (121) and may be arranged in contact with the inner surface of the carbonization furnace (121).

[0129] Accordingly, the plurality of scraping members (120b2) can agitate the ash by scraping the inner surface of the carbonization furnace (121) at a plurality of locations when the carbonization furnace (121) rotates.

[0130] At this time, a plurality of scraping members (120b2) can be arranged at a preset angle with respect to the support frame (120b1).

[0131] Accordingly, the plurality of scraping members (120b2) can move forward or backward in response to the rotational direction of the carbonization furnace (121) to scrape the inner surface of the carbonization furnace (121).

[0132] That is, when the carbonization furnace (121) rotates clockwise, the plurality of scraping members (120b2) move toward the front side of the carbonization furnace (121) to scrape the inner surface of the carbonization furnace (121), and when the carbonization furnace (121) rotates counterclockwise, the plurality of scraping members (120b2) move toward the rear side of the carbonization furnace (121) to scrape the inner surface of the carbonization furnace (121).

[0133] For example, a plurality of scraping members (120b2) may be arranged at an angle of 5 degrees or more and 15 degrees or less with respect to the support frame (120b1).

[0134] Each of the plurality of scraping members (120b2) may include a spiral coil portion (CM) and a scraping portion (SCM).

[0135] The spiral coil portion (CM) is coupled to the support frame (120b1) and can be restored to its original position by elastic force when an external force is applied.

[0136] For example, the spiral coil portion (CM) can be formed in the shape of a coil spring.

[0137] The scraping section (SCM) is arranged at an end of the spiral coil section (CM) and can be elastically supported by the spiral coil section (CM).

[0138] The scraping section (SCM) is in contact with the inner surface of the carbonization furnace (121) and can scrape the inner surface of the carbonization furnace (121) when the carbonization furnace (121) rotates.

[0139] For example, the scraping section (SCM) can be formed in the shape of a straight bar.

[0140] Referring to FIG. 14, the carbonization equipment (120) may further include a scratching roller (120c).

[0141] The scratching roller (120c) is accommodated inside the carbonization furnace (121), and when the carbonization furnace (121) rotates, it rotates inside the carbonization furnace (121) together with the shaft powder, crushing the shaft powder and scratching the inner surface of the carbonization furnace (121), thereby preventing the shaft powder from adhering to the inner surface of the carbonization furnace (121).

[0142] The scratching roller (120c) may include a cylindrical roller body (RB) and a plurality of scratching pins (SP) arranged in a plurality around the roller body (RB) along the axial direction of the roller body (RB).

[0143] A plurality of scratching pins (SP) can scrape the inner surface of the carbonization furnace (121) while crushing the shaft powder when the scratching roller (120c) rotates.

[0144] For example, the scratching roller (120c) can be formed of a stainless steel material having a preset length and weight.

[0145] Meanwhile, although not shown in the drawing, the scratching roller (120c) may scrape the entire inner surface of the carbonization furnace (121) while moving along the axial direction of the carbonization furnace (121) inside the carbonization furnace (121) according to the internal design of the carbonization furnace (121).

[0146] That is, since the present porous high-function biochar manufacturing device has a scraper (120b) and a scratching roller (120c) arranged inside the carbonization furnace (121) to constantly scrape the inner surface of the carbonization furnace (121) when the carbonization furnace (121) rotates, the coking phenomenon in which the remaining livestock matter in the carbonization furnace (121) adheres to the inner surface of the carbonization furnace (121) can be prevented, and thus, a decrease in thermal conductivity due to the coking phenomenon can be prevented.

[0147] In addition, the porous high-performance biochar manufacturing device adopts a heat storage structure, thereby reducing the energy cost used for heating the carbonization furnace (121).

[0148] Referring to FIGS. 1 to 10, the biochar manufacturing device (100) may further include a sludge transfer screw (130), a fermentation device (140), a pellet forming device (150), a gas-liquid separation device (160), a cooling condensation device (170), and a wastewater fermentation tank (180).

[0149] The sludge transfer screw (130) can transfer the sludge of solid matter discharged from the outlet side of the discharge transfer screw (128) after the carbonization process.

[0150] At this time, the sludge of solid matter transported by the sludge transport screw (130) can be transported to the sludge hopper (131).

[0151] The fermentation facility (140) can ferment sludge moved by the sludge transfer screw (130).

[0152] At this time, the sludge fed into the sludge hopper (131) can be supplied into the fermentation facility (140) through a separate transport means.

[0153] The pellet forming facility (150) can pelletize the sludge fermented in the fermentation facility (140) into a preset size.

[0154] At this time, the sludge fermented in the fermentation facility (140) can be supplied into the pellet forming facility (150) through a separate transport means.

[0155] Meanwhile, pellets manufactured by the pellet molding equipment (150) can be packaged and shipped after passing through a small packaging weigher (191) and a vinyl adhesive machine (192).

[0156] The gas-liquid separation facility (160) can separate odorous gas and water vapor from carbonized material discharged from the outlet side of the carbonization furnace (121).

[0157] The cooling condensation facility (170) can re-cool and condense the water vapor separated from the gas-liquid separation facility (160) to store the condensate.

[0158] The cooling condensing facility (170) may include a plurality of condensers (171), a plurality of temporary storage tanks (172) and a distilled water tank (173).

[0159] The plurality of condensers (171) are configured in a multi-layer structure so that water vapor can pass through the inside and cooling water can pass through the outside.

[0160] Accordingly, the steam is cooled and separated into distilled water, and the separated distilled water is discharged downward and sent to a temporary storage tank (172) and then stored in a distilled water tank (173).

[0161] And, the distilled water stored in the distilled water tank (173) passes through a reverse osmosis filter (not shown) to remove ionic substances and heavy metals, and is cooled and ozone-treated to remove odors, so that it can become atmospheric distilled water.

[0162] For example, the type of condenser (171) is shell and tube and can be manufactured as vertical and spray types.

[0163] The wastewater fermentation tank (180) can remove any remaining odor in the condensed water condensed in the cooling condensation facility (170).

[0164] The wastewater fermentation tank (180) is equipped with an ozone generator (not shown), which generates ozone to remove any remaining odor in the condensed water condensed in the cooling condensation facility (170).

[0165] Hereinafter, a method for accumulating large-capacity livestock waste resources according to an embodiment of the present invention (hereinafter referred to as “accumulating large-capacity livestock waste resources method”) will be described.

[0166] For reference, for the convenience of explanation, the same drawing symbols used in explaining the porous high-performance biochar manufacturing device (100) will be used for each component to explain the large-capacity biochar resource recovery method of this storage type, and the same or duplicate explanations will be omitted.

[0167] Figure 15 is a flowchart showing a large-capacity storage resource recovery method according to an embodiment of the present invention.

[0168] Referring to FIGS. 1 and 15, the method for regenerating large-capacity livestock manure resources first supplies a large amount (e.g., 10 tons or more) of livestock manure containing moisture (moisture content of approximately 78%) into a supply hopper (111), and feeds the manure into an input hopper (114) while a supply transfer screw (112) rotates, and feeds the manure into a carbonization furnace (121) of a carbonization facility (120) by the rotation of the input transfer screw (113) (S10).

[0169] Next, the inside of the carbonization furnace (121) is made into an oxygen-free atmosphere, and the carbonization furnace (121) is rotated and heated to carbonize the livestock manure (S20).

[0170] At this time, an inert gas (argon, nitrogen, helium, etc.) is injected into the carbonization furnace (121) to create an atmosphere where oxygen is blocked.

[0171] Next, the discharge transfer screw (128) installed on the outlet side of the carbonization furnace (121) rotates to discharge the carbonized carbide (S30).

[0172] Next, the sludge transfer screw (130) rotates to separate and transfer the sludge of solids from the carbonized material (S40).

[0173] At this time, the sludge of solid matter is transferred to the sludge hopper (131) by the sludge transfer screw (130), and the sludge supplied through the sludge hopper (131) is fed into the fermentation facility (140). For example, it is preferable that the moisture content of the sludge be 10%.

[0174] Next, the fermentation facility (140) ferments the sludge (S50).

[0175] At this time, the fermentation bacteria can be changed to various known fermentation bacteria.

[0176] Next, the pellet forming facility (150) pelletizes the sludge fermented in the fermentation facility (140) into a preset size (S60).

[0177] At this time, the pellets manufactured by the pellet molding equipment (150) are packaged and shipped after passing through a small packaging weigher (191) and a vinyl adhesive machine (192).

[0178] Next, the gas-liquid separation facility (160) separates odorous gas and water vapor from the carbonized material discharged from the carbonization furnace (121) (S70).

[0179] Next, the cooling condensation facility (170) cools and condenses the water vapor separated from the gas-liquid separation facility (160) again to store the condensate (S80).

[0180] Next, the wastewater fermentation tank (180) removes any remaining odor in the condensate condensed in the cooling condensation facility (170) (S90).

[0181] In this way, according to an embodiment of the present invention, not only can a large amount of livestock waste be effectively and quickly recycled in an environmentally friendly manner, but also bad odors around the farm can be fundamentally prevented, and environmental pollution can be effectively prevented by condensing and fermenting wastewater to convert it into distilled water.

[0182] In addition, high-moisture content (approximately 78% or more) manure can be fermented to low-moisture content (10% or less) to produce large quantities of fermented manure compost, maximizing profits.

[0183] In addition, the completely sealed structure of the carbonization facility prevents the leakage of odorous gases during the carbonization process, and the odorous gases generated during the carbonization process are fed back and then incinerated, thereby fundamentally blocking the generation of odors.

[0184] In addition, the input conveying screw is manufactured as a special wear shoe type screw to effectively prevent backflow, and a shutter is installed to prevent backflow of steam and gas.

[0185] In addition, it is composed of a rotating kiln-type storage structure for carbonization, so it has an excellent energy-saving effect due to the continuous heat retention effect after heating once.

[0186] In addition, the inclined spiral blades inside the carbonizer enable efficient movement and uniform stirring of the pellets, thereby producing uniform pellet products during subsequent pellet processing.

[0187] In addition, in order to prevent a decrease in thermal conductivity due to a phenomenon (coking phenomenon) in which foreign substances such as carbohydrates or proteins in the manure adhere to the inside of the carbonizer and cause a mess, thereby reducing heat transfer efficiency, the inside of the carbonizer is cleaned, the inside of the carbonizer is prevented from coking, and the thermal conductivity is maximized. In addition, an automatic carbon discharge function is provided after complete carbonization and drying.

[0188] In addition, the manure supply facility (110) is configured to automatically open and close the outlet depending on whether the manure is discharged, and to seal the connection between the manure supply facility (110) and the carbonization facility (120), so that not only is it possible to prevent water vapor and gas inside the carbonization facility (120) from flowing back into the manure supply facility (110) but also to prevent water vapor and gas inside the carbonization facility (120) from leaking to the outside through the connection between the manure supply facility (110) and the carbonization facility (120).

[0189] In addition, since a scraper (120b) and a scratching roller (120c) are arranged inside the carbonization furnace (121) to constantly scrape the inner surface of the carbonization furnace (121) when the carbonization furnace (121) rotates, a coking phenomenon in which the remaining stock in the carbonization furnace (121) adheres to the inner surface of the carbonization furnace (121) is prevented, and thereby a decrease in thermal conductivity due to the coking phenomenon is prevented, thereby reducing the energy cost used for heating the carbonization furnace (121).

[0190] Although the embodiments of the present invention have been described in more detail with reference to the attached drawings, the present invention is not necessarily limited to these embodiments, and various modifications may be implemented without departing from the technical spirit of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical spirit of the present invention, but to explain it, and the scope of the technical spirit of the present invention is not limited by these embodiments.
