Description

Technology Field

[0001] The present invention relates to a livestock manure treatment device and a method thereof. Background Technology

[0003] In general, livestock manure is continuously generated due to the development of the livestock industry, and if not properly treated, it can cause problems such as foul odors and environmental pollution. Accordingly, various methods have been proposed to treat livestock manure.

[0004] For example, the method of composting livestock manure is widely used. This method has the advantage of allowing the manure to be fermented and utilized as fertilizer, but it has the drawbacks of requiring a long time for fermentation and a large site.

[0005] In addition, methods of treating livestock manure in the form of liquid fertilizer are also being used. However, this method can generate foul odors during the treatment process and poses a risk of water pollution if improperly managed.

[0006] In addition, while there is a method of simply storing livestock manure, this can lead to the generation of harmful gases and severe odor problems, posing a negative impact on the surrounding environment.

[0008] The sludge reduction treatment system of Korean Registered Patent Publication No. 10-2213606, which is a prior art related to the present invention, comprises: a treatment unit configured to apply heat to the mixed sludge and stir it internally, and configured to allow the introduction of mixed sludge mixed with sawdust and microorganisms into the sludge so as to be driven by the control of a control unit to lower the moisture content of the sludge, and to allow the discharge of dried sludge with reduced moisture content by forming an inlet on one side, and configured to allow the introduction of mixed sludge into the treatment unit to be stirred while applying heat; a cooling scrubbing tower configured to supply dry air into the treatment unit by spraying cleaning water while the exhaust gas generated when reducing the mixed sludge in the treatment unit is introduced downward and flowed upward, thereby removing water vapor contained in the exhaust gas; and a cooling tower configured to be installed on one side of the cooling scrubbing tower and connected to a cleaning water circulation pipe equipped with a cleaning water circulation pump to cool and supply cleaning water.

[0009] However, the above prior art has a problem in that, as the temperature of the exhaust gas drops rapidly during the cooling and cleaning process by spraying cleaning water to remove water vapor contained in the exhaust gas and supplying dry air into the treatment unit, the temperature of the re-introduced dry air becomes low, making it difficult to maintain the temperature inside the treatment unit, and consequently, the drying efficiency of the sludge decreases, which leads to energy waste as the heater is operated again to raise the temperature inside the treatment unit.

[0010] In addition, the aforementioned prior art has a problem in that the cleaning efficiency gradually decreases as the contamination level of the cleaning cooling water increases due to the physical contact of the exhaust gas with the cooling water introduced from the cooling tower and the exhaust gas in the cooling scrubbing tower, thereby generating condensed water.

[0012] Therefore, there is a growing need for a new livestock manure treatment device and method capable of solving the aforementioned problems of energy waste and cooling water contamination. Prior art literature

[0014] 1. Korean Registered Patent Publication No. 10-2213606 The problem to be solved

[0015] The present invention has been devised to solve the aforementioned problems, and the objective of the present invention is to provide a livestock manure treatment device and a method thereof that rapidly lower the moisture content of livestock manure to convert it into solid fuel, while simultaneously removing odors and harmful gases generated during the treatment process and recovering purified moisture.

[0017] Another objective of the present invention is to provide a livestock manure treatment device and a method thereof that can maximize energy efficiency during livestock manure treatment and fundamentally prevent cooling water contamination by exhaust gas.

[0019] Another objective of the present invention is to provide a livestock manure treatment device and a method thereof that can reduce the time required for manure treatment work at farms by increasing management efficiency through remote control of the livestock manure treatment device. means of solving the problem

[0021] To solve the above problem, a livestock manure treatment device having a vacuum evaporation and non-contact cooling structure, which is an embodiment of the present invention, may include an evaporation unit that reduces the pressure through a vacuum pump while livestock manure is introduced and then heats the livestock manure through a heater unit; a condensation unit that condenses harmful gas discharged from the evaporation unit through a harmful gas discharge pipe to generate condensate water, which is then transferred to a condensate water storage tank while simultaneously transferring uncondensed residual harmful gas to a scrubbing tower; a scrubbing tower that scrubs the residual harmful gas discharged from the condensation unit; and a control unit that receives sensor values ​​output from a plurality of installed sensors and controls the pressure and temperature of the evaporation unit.

[0023] According to one embodiment of the present invention, the condenser is characterized in that harmful gas is introduced into the internal space of the condenser through a harmful gas inlet and then condenses into harmful gas by contacting the surface of a cooling water transfer pipe along a predetermined path, and the generated condensate is introduced into a condensate storage tank located at the bottom through a condensate discharge pipe, while the uncondensed residual harmful gas is introduced into a vacuum pump through a residual harmful gas transfer pipe.

[0025] According to one embodiment of the present invention, a receive tank may be further included, which is installed between a condenser and a scrubbing tower and removes fine droplets contained in the uncondensed residual harmful gas flowing out from the condenser to transfer only the residual harmful gas in a pure gaseous state to the scrubbing tower.

[0027] According to one embodiment of the present invention, the control unit controls the input pump, vacuum pump, and heater unit of a livestock manure treatment device using a preset input pump operation value, a preset vacuum state value, and a preset heater value based on the input weight when the user sets the input weight in daily / weekly / monthly units using an input weight setting screen of a user terminal.

[0029] Another embodiment of the present invention, a livestock manure treatment method having a vacuum evaporation and non-contact cooling structure, may include the steps of: introducing livestock manure into an evaporator and then depressurizing; heating the livestock manure introduced into the evaporator; condensing harmful gases generated from the evaporator to physically purify them in the first step; and chemically purifying uncondensed harmful gases in the second step. Effects of the invention

[0031] The present invention can drastically reduce the thermal energy required for evaporation by maintaining the inside of the evaporator under reduced pressure to lower the boiling point of livestock manure to a range of 70 to 90°C.

[0032] In addition, by adopting a non-contact heat exchange structure in which the cooling water and harmful gases do not come into direct contact through the condenser (cooling chiller), contamination of the cooling tower and circulating cooling water can be fundamentally prevented.

[0033] In addition, ammonia and hydrogen sulfide can be removed in stages through a multi-stage purification structure that combines primary physical condensation in the condenser (cooling chiller) and secondary chemical neutralization in the scrubbing tower. In particular, by first liquefying water vapor in the condenser (cooling chiller) to minimize the volume of gas entering the scrubbing tower, cleaning efficiency can be maximized and the odor concentration of the final exhaust gas can be controlled below legal standards.

[0034] In addition, as livestock manure is treated at low temperatures within a closed, vacuum-sealed structure, the destruction of organic nutrients in the solids is minimized, making it possible to produce high-quality fertilizer. Brief explanation of the drawing

[0039] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted.

[0041] FIGS. 1a to 1c are perspective views for explaining a livestock manure treatment device according to various embodiments of the present invention.

[0042] Referring to FIGS. 1a to 1c, the livestock manure treatment device (1000) may include an evaporator (100) that heats the livestock manure through a heater unit (150 in FIG. 3) after depressurizing it through a vacuum pump (400) while the livestock manure is introduced; a condenser (210) that condenses harmful gas discharged from the evaporator through a harmful gas discharge pipe (130) to transfer the generated condensate to a condensate storage tank (600) and simultaneously transfers the uncondensed residual harmful gas to a scrubbing tower; a scrubbing tower (300) that scrubs the residual harmful gas discharged from the condenser; and a control unit (700) that controls the pressure and temperature of the evaporator by receiving sensor values ​​output from a plurality of installed sensors.

[0044] The evaporator (100) can receive livestock manure from a manure storage tank (10) in which livestock manure is stored, through a manure inlet (20) and a manure inlet pipe (30) by means of an input pump (11). The evaporator (100) can apply heat to the livestock manure after forming a predetermined vacuum state inside the evaporator to remove harmful substances such as ammonia and hydrogen sulfide contained in the input livestock manure and simultaneously produce solidified dried manure. The evaporator (100) can reduce the internal pressure of the evaporator to a range of 0.2 atm to 0.7 atm, which is lower than atmospheric pressure, by operating a vacuum pump (400) under the control of a control unit using a predetermined vacuum state value. The evaporator (100) may be constructed with a structure sealed from the outside to maintain this reduced pressure state, and to seal the housing between the rotating shaft of the agitator motor (110) that rotates the internal impeller (blade) to agitate the input livestock manure and the housing, a liquid film (lubricating film) may be formed between the precisely machined cross-section of the 'rotating ring' that rotates together with the rotating shaft and the 'fixing ring' fixed to the housing to reduce friction and block the inflow of air. Meanwhile, at connection parts that require separation, such as the dry manure discharge window (120) for discharging the dry manure of the evaporator (100) to the outside, a rubber O-ring may be fitted and compressed with a bolt or the like to seal the evaporator. The evaporator (100) includes a heating unit (150) containing a heating pipe or heating coil at the bottom of the evaporator. The control unit can operate the heating unit (150) using a preset heating value to set the internal temperature of the evaporator to a range of 45°C to 90°C. Meanwhile, in order to preheat the livestock manure introduced into the evaporator (100) from the manure storage tank (10) through the manure input pipe (30), a preheating unit (151) consisting of a heating pipe or a heating coil may be further included in a part of the manure input pipe (30).The preheating unit (151) can prevent thermal shock, which causes the temperature inside the evaporation unit to temporarily drop when livestock manure at room temperature is introduced into the evaporation unit having a predetermined temperature. That is, the control unit controls the preheating unit (151) using a predetermined heating state value to introduce livestock manure into the evaporation unit (100) in a state close to the evaporation temperature of the livestock manure, thereby maintaining the evaporation rate, which reduces the load of the heating unit (150) and simultaneously ensures work continuity, thereby increasing the processing capacity of livestock manure. In relation to such energy management, the livestock manure treatment device (1000) of the present invention may further include a heat exchanger (15) that lowers the temperature of harmful gas discharged from the evaporation unit before it is introduced into the condensation unit (210). The heat exchanger (15) can be formed by the harmful gas discharge pipe (130) passing through the interior of the manure storage tank (10) for a predetermined length. That is, by transferring the heat contained in the harmful gas to the livestock manure stored in the manure storage tank (10), the temperature of the harmful gas is lowered, thereby reducing the cooling load of the condenser (210) and preheating the livestock manure in the manure storage tank (10), thereby reducing the power consumption of the preheating unit (151) and the heating unit (150), thus saving energy by utilizing waste heat. In addition, as the volume of the harmful gas decreases as its temperature drops through the heat exchanger, the volume of gas that the vacuum pump must suck in is reduced, which can contribute to improving the efficiency of the vacuum pump and assisting in maintaining a predetermined vacuum state formed by the vacuum pump.

[0045] Meanwhile, the evaporator (100) may be equipped with various sensors to detect the internal state of the evaporator, such as a pressure sensor (40) for measuring the internal pressure of the evaporator, a temperature sensor (40) for measuring the temperature, and a humidity sensor (not shown) for measuring humidity, in a predetermined area. A plurality of sensors located inside the evaporator can transmit sensor values ​​to a control unit.

[0046] Meanwhile, multiple valves capable of controlling transfer may be installed in the manure input pipe, hazardous gas discharge pipe, and uncondensed residual hazardous gas transfer pipe to regulate the input amount and pressure. These multiple valves can be opened and closed by the control of the control unit. In addition, various transfer pumps (not shown) that can be used for manure input, cooling water transfer, and uncondensed residual hazardous gas transfer may also be operated by the control of the control unit. The basic purpose of such control is to create a vacuum state in the evaporator, and each valve and transfer pump can be controlled based on a predetermined vacuum state value.

[0048] FIG. 3 is a block diagram illustrating a livestock manure treatment device according to various embodiments of the present invention, and FIG. 4 is a flowchart illustrating a livestock manure treatment device according to various embodiments of the present invention. Hereinafter, with reference to FIG. 3 and FIG. 4, a process will be described in which harmful gases generated from an evaporator are physically purified first by a condenser, and the remaining uncondensed harmful gases are chemically purified second by a scrubbing tower.

[0050] 1. Pressure reduction and heating of the evaporator (S41, S43)

[0052] With livestock manure introduced into the evaporator, the control unit (700) can operate the vacuum pump (400) to reduce the internal pressure of the evaporator using a predetermined vacuum state value, and then the control unit (700) can operate the heater unit (150) using a predetermined heater value to apply heat to the livestock manure. In this reduced-pressure state, the livestock manure heated can easily vaporize at a temperature much lower than atmospheric pressure as the force pressing on the surface of the livestock manure weakens. That is, water, ammonia, hydrogen sulfide, etc. contained in the livestock manure can very rapidly transform into harmful gases at a temperature lower than atmospheric pressure in a reduced-pressure state. The generated harmful gases can be formed by mixing not only water vapor but also harmful substances such as ammonia and hydrogen sulfide, which are the cause of bad odors.

[0053] Meanwhile, in this reduced pressure state, the generated harmful gas can move rapidly along the harmful gas discharge pipe (130) to the condensation section (210) and lose heat through a non-contact method with cold cooling water in the condensation section (210), thereby changing into liquid condensate. This can perform an auxiliary function of maintaining the vacuum inside the evaporation section (100) as the expanded harmful gas generated in the reduced pressure state changes into liquid condensate in the condensation section and its volume contracts instantaneously. That is, as the harmful gas is converted into liquid during the condensation process, the amount of gas in the system decreases, which can contribute to the maintenance of a predetermined vacuum state formed by the vacuum pump. The livestock manure treatment device (1000) can provide a physical environment in which heating livestock manure in the reduced pressure state of the evaporation section allows for the primary separation of moisture and harmful gas at a lower temperature and more rapidly.

[0054] For example, to remove moisture and harmful substances in livestock manure at atmospheric pressure, heat of 100°C must be applied, but in reduced pressure due to vacuum, in the range of 0.1 to 0.7 atmospheres, harmful gases can be generated more quickly at a lower temperature even with less heat of 45°C to 90°C applied. Depending on the reduced pressure state, the control unit can control the heating unit of the evaporator so that the temperature does not rise above a certain level.

[0055] Therefore, since moisture can be removed from livestock manure at a lower temperature within the reduced pressure range rather than at 100°C at atmospheric pressure to produce dry manure, the deformation of organic matter is relatively minimal, and the nutrient destruction of organic fertilizer can be minimized.

[0057] 2. Condensing harmful gas discharged from the evaporator (S45)

[0059] Harmful gas generated inside the evaporator (100) can be introduced into the condenser through the harmful gas discharge pipe (130).

[0060] FIGS. 2a and 2b are drawings for explaining a process of primarily removing harmful gases according to various embodiments of the present invention.

[0062] Referring to FIGS. 2a and 2b, the condensation unit (210) extracts heat from the harmful gas introduced through the harmful gas discharge pipe (130) by non-contact with the cooling water introduced from the cooling tower to produce condensed water, and at the same time, the uncondensed residual harmful gas can be introduced into the vacuum pump (400).

[0063] The cooling tower (200) can absorb the heat of harmful gases in the condensation section (210), cool the cooling water whose temperature has risen, and supply it to the condensation section (210) using a cooling water circulation pump (not shown).

[0064] The cooling water generated in the cooling tower (200) can be forcibly flowed into the cooling water transfer pipe (215) through the cooling water inlet (215) of the condenser by a cooling water circulation pump (not shown) installed in the cooling tower, and then transferred back to the cooling tower through the cooling water outlet (216).

[0065] The harmful gas introduced through the harmful gas discharge pipe (130) is introduced into the internal space of the condenser through the harmful gas inlet (217) of the condenser (210), and then changes into condensate by losing heat through contact with the surface of the cooling water transfer pipe (215) along a predetermined path. The generated condensate is introduced into the condensate storage tank (600) located at the bottom through the condensate discharge pipe (212), and at the same time, the uncondensed residual harmful gas can be introduced into the vacuum pump (400) through the residual harmful gas transfer pipe (213). Since the condensate discharge pipe (212) is connected to the residual harmful gas transfer pipe (213) in a reduced pressure state, the air inside the condensate storage tank (600) and the generated condensate can flow back toward the vacuum pump (400). Therefore, such backflow can be prevented by bending the bottom of the condensate discharge pipe (212) into a 'U' shape so that it is always filled with condensate, or by immersing the bottom of the condensate discharge pipe (212) below the water level of the condensate storage tank (600). Another method is to form an intermediate chamber at the bottom of the condensate discharge pipe (212), and install a check valve and a solenoid valve at the front and rear ends of the intermediate chamber so that when one side is opened, the other side is closed by a control unit, thereby allowing the condensate to be discharged through the condensate discharge pipe (212) to the condensate storage tank (600) located at the bottom while maintaining a vacuum state in the residual harmful gas transfer pipe (213).

[0066] Since the harmful gas and cooling water generate condensate through heat exchange by a non-contact method, the cooling water can fundamentally prevent contamination by contact with the harmful gas. Therefore, the harmful gas discharged from the evaporator can be primarily purified by the condenser (210) through which water-soluble gases such as ammonia contained in the harmful gas come into contact with the cooling water to generate condensate.

[0067] Meanwhile, uncondensed residual harmful gas can be transferred to a receive tank (500) through a vacuum pump (400) and a residual harmful gas transfer pipe (411). Check valves (not shown) may be installed at the front and rear ends of the vacuum pump (400) to prevent backflow of the harmful gas discharged from the evaporator from the condenser (210) to the receive tank (500).

[0068] In the receive tank (500), although condensate is primarily separated in the condensation section (210), fine droplets (Mist) that are not completely removed due to the high flow rate may be mixed with the residual harmful gas. As the flow rate of these fine droplets slows down rapidly inside the receive tank, the remaining liquid sinks to the bottom, and only the residual harmful gas in a pure gaseous state escapes to the top of the receive tank, thereby acting as a buffer to block the inflow of liquid into the scrubbing tower. Additionally, the receive tank (500) is a buffer with a fixed internal space and is located between the vacuum pump (400) and the scrubbing tower (300) to constantly regulate the pressure and flow rate of the residual harmful gas.

[0070] 3. Wash the uncondensed residual harmful gas flowing into the scrubbing tower (S46)

[0072] Uncondensed residual harmful gas can be discharged from the top of the receive tank (500) and flow into the bottom of the scrubbing tower (300) through the residual harmful gas transfer pipe (320). The residual harmful gas flowing in through the bottom gas inlet (320) of the scrubbing tower (300) can rise to the top of the scrubbing tower due to pressure. The scrubbing tower (300) may include a packing layer filled with packing material such as a Pall Ring or Tellerette to maximize the contact area between the residual harmful gas and the scrubbing liquid, and a scrubbing liquid spraying unit capable of finely spraying the scrubbing liquid (water or chemical agent) like mist from the top to the bottom of the scrubbing tower. The scrubbing liquid may be alkaline or acidic, and water-soluble and insoluble malodorous components such as ammonia and hydrogen sulfide present in the residual harmful gas can be chemically removed through a neutralization reaction. The remaining harmful gas can be secondarily purified by meeting the cleaning liquid sprayed from the cleaning liquid spraying unit and the packing bed while rising inside the cleaning tower. Meanwhile, the cleaning tower (300) may have a structure in which the remaining harmful gas can continuously circulate inside the cleaning tower by forming a vertical transfer pipe (310) to transfer the remaining harmful gas that has risen to the top back to the bottom of the cleaning tower. As the remaining harmful gas continuously circulates and comes into contact with the cleaning liquid and the packing bed, it can generate even more purified air.

[0074] 4. Discharge purified air from the scrubbing tower to the outside (S47,48)

[0076] The control unit can detect the air quality inside the scrubbing tower through a gas detection sensor (not shown) located at the top of the scrubbing tower (300). The control unit (700) can discharge purified air inside the scrubbing tower to the outside by controlling the opening and closing of a discharge control valve located in an air discharge pipe (not shown) formed at the top. That is, the control unit (700) measures the air pollution concentration inside the scrubbing tower in real time through the gas detection sensor and, using a preset air discharge standard, can open the discharge control valve to discharge purified air to the outside when the current air pollution concentration is within the standard value. Meanwhile, if the current air pollution concentration is above the standard value, the control unit closes the discharge control valve, thereby allowing the remaining harmful gas to continuously circulate from inside the scrubbing tower along the vertical transfer pipe (310), so that the purification process can be continuously performed.

[0078] FIG. 5 is a schematic diagram illustrating remote control of a livestock manure treatment device according to various embodiments of the present invention, and FIGS. 6a to 6d illustrate app screens installed on a user terminal for remotely managing a livestock manure treatment device according to various embodiments of the present invention.

[0080] Referring to FIGS. 5 to 6c, the livestock manure treatment device (1000) can be remotely controlled via a user terminal (2) in a network (1) environment and can monitor the current operating environment of the livestock manure treatment device. Referring to FIGS. 6a and 6b, the livestock manure treatment device can be remotely turned on / off via an app installed on the user terminal (2), and the input weight, output amount, power consumption, heater temperature, odor level, etc. for the corresponding date can be remotely monitored.

[0081] Also, referring to FIG. 6c, when a user sets an input weight in units of day / week / month using the input weight setting screen (610) of the user terminal, the management server (3) receives this and transmits it to the control unit, and the control unit (700) controls the input pump, vacuum pump, and heater unit of the livestock manure treatment device using the input pump operation value, the input state value, the input state value, the input heater value, etc. according to the input weight, thereby allowing the livestock manure treatment device to be easily controlled remotely.

[0083] Although the present invention has been described in detail above through representative embodiments, those skilled in the art will understand that various modifications can be made to the above-described embodiments within the scope of the present invention.
