Description

Engine power generation combined cavitation sterilization and disinfection system

[0001] The present invention relates to an engine-powered combined cavitation sterilization and disinfection system, and more particularly, to an engine-powered combined cavitation sterilization and disinfection system that selectively operates power supply and sterilized drinking water supply by continuous operation according to day / night or set time periods.

[0002] The utilization rate of water stored in domestic reservoirs is extremely low, at less than 5% of the total reservoir capacity. Therefore, to efficiently utilize reservoir water, a groundbreaking shift in thinking in government-led water management policies is urgently needed.

[0003] For example, reservoirs and groundwater need to be transformed into emergency water for emergencies such as drought, flood, water quality accidents, nuclear accidents, or terrorism. Furthermore, they need to become cyclical strategic resources that require appropriate development and ongoing management, unlike oil and coal resources, as high-quality drinking water and life-giving water that can improve the health and quality of life of the people.

[0004] In addition, energy, which relies on imports for over 90%, especially for facilities for power generation, is an urgent task that must be developed along with the efficient use of reservoirs or groundwater.

[0005] Accordingly, in the above context, technologies for combining diesel generators and water supply systems to use them for drinking water, etc. have been announced.

[0006] However, the technologies mentioned above have many problems. For example, if we look at the technology that combines a diesel generator and a water supply system, the sterilization and disinfection process, which is a pretreatment process for use as drinking water, is mainly due to chemical action mechanisms, and it also has the problem that it is difficult to maintain stable water quality because it is impossible to actively respond to changes in flow rate or water quality.

[0038] Figure 1 is a configuration diagram of an engine power generation combined cavitation sterilization and disinfection system according to the present invention.

[0039] Referring to FIG. 1, the engine power generation combined cavitation sterilization and disinfection system according to the present invention is basically composed of a cooling device (10), a generator (20), a first clutch (30), a drive control unit (40), a drinking water supply line (50), a hydrogen peroxide (H2O2) supply line (60), a cavitation unit (70), a second clutch (80), a drinking water storage tank (90), and a control unit (100).

[0040] According to an embodiment of the present invention, the cooling device (10) is provided to prevent deformation or damage of the engine (1) due to high temperature heat when the engine (1) is driven, and is specifically composed of a circulation pump and a cooling means.

[0041] Here, the engine (1) may include all existing four-stroke internal combustion engines, such as diesel engines and gasoline engines.

[0042] The circulation pump constituting the above cooling device (10) is installed on one side of the engine (1) and supplies water (coolant) from an external coolant supply source to the coolant tank inlet of the engine (1).

[0043] In addition, the cooling means constituting the above cooling device (10) performs the function of cooling high-temperature water stored in the cooling water tank.

[0044] In the present invention, the cooling means may be configured to include a radiator and a radiator cooling fan, and an exhaust pipe for discharging high-temperature and humid air generated by the radiator cooling fan to the outside, or may be configured to include a plate-type heat exchanger (110), or may be configured to include a radiator and a radiator cooling fan, an exhaust pipe for discharging high-temperature and humid air generated by the radiator cooling fan to the outside, and a plate-type heat exchanger (110) connected between the engine (1) and the cooling means.

[0045] At this time, the plate heat exchanger (110) is configured to be connected to the heat storage tank (112) by piping so that heat circulates between the heat storage tanks (112) by the operation of the circulation pump (111).

[0046] According to an embodiment of the present invention, the generator (20) is connected to the engine (1) to produce power by the output of the engine (1), and is configured to supply the produced power to each receiving location (or receiving party) or store it in an ESS battery (21), as shown in FIG. 1.

[0047] According to an embodiment of the present invention, the first clutch (30) is provided inside the engine (1) and is configured to allow or release the transmission of output by the driving force of the engine (1) to the generator (20).

[0048] In addition, according to an embodiment of the present invention, the drive control unit (40) is configured to selectively supply power of the generator (20) to each receiving location and ESS battery (21) according to a signal of the control unit (100) to be described later.

[0049] At this time, the drive control unit (40) can control power to be supplied only to the ESS battery (21) when the power demand of each receiving location is lower than a predetermined value.

[0050] For example, the drive control unit (40) can be configured to cut off the power supply to each receiving location during the early morning hours when the power demand is relatively low, and store the power produced by the engine (1) only in the ESS battery (21).

[0051] As described above, the ESS battery (21) storing power can be used as a power supply source when self-generation by the engine (1) is impossible due to environmental factors such as a breakdown of the engine (1) or a natural disaster.

[0052] According to an embodiment of the present invention, the drinking water supply line (50) is configured such that one end is connected to an external drinking water supply source (e.g., a reservoir), and a pump (51) is operated by the output of the engine (1) to supply water from the external drinking water supply source.

[0053] According to a further embodiment of the present invention, a contaminant remover (52) may be provided between the drinking water supply line (50) and the cavitation unit (70) to remove or filter various contaminants including floating substances from water supplied from an external drinking water supply source.

[0054] Additionally, according to an embodiment of the present invention, the hydrogen peroxide (H2O2) supply line (60) is connected to a pipe branched from the drinking water supply line (50).

[0055] At this time, a small amount of hydrogen peroxide can be injected into the hydrogen peroxide supply line (60), and the hydrogen peroxide injected through the hydrogen peroxide supply line (60) acts to increase the sterilization and disinfection function for water in the cavitation unit (70) described later.

[0056] Meanwhile, according to an embodiment of the present invention, the cavitation unit (70) is connected to the other end of the drinking water supply line (50) and is configured to receive water moving through the drinking water supply line (50) and cause a cavitation sterilization reaction.

[0057] To this end, the cavitation unit (70) according to the present invention may be composed of a drive shaft rotation part (71), a cavitation generating means (72), a water inlet part (73), and an impeller part (74).

[0058] Fig. 3 is a drawing showing the appearance of the cavitation unit (70) shown in Fig. 1. Referring to Fig. 3, the drive shaft rotation part (71) is fixedly installed on one side of the fixed frame (71a), and is connected to a rotation shaft (71b) that rotates at a constant speed according to a preset control command, and functions to rotate together with the rotation shaft (71b).

[0059] The above cavitation generating means (72) is coupled to the end of the drive shaft rotating part (71) and has the function of causing a shearing and cavitation reaction in the water flowing into it with a rapid rotational force and then discharging it to the outside.

[0060] More specifically, in order to perform the function as described above, the cavitation generating means (72) may be configured to include a rotor (72a), a stator (72b), a housing (72c), a discharge member (72d), and a UV-C LED (72e).

[0061] FIG. 5 is a drawing showing the planar shape of a rotor (72a) among the components of the cavitation unit (70) shown in FIG. 1, and FIG. 6 is a vertically cut exploded perspective view of the cavitation unit (70) shown in FIG. 1.

[0062] Referring to FIGS. 5 and 6, the rotor (72a) constituting the cavitation generating means (72) has a plurality of water passage holes (72a-1) formed in a concentric circle spaced apart from the center by a certain interval and having a certain slope in the cross-section in the direction of the arc.

[0063] The stator (72b) constituting the above cavitation generating means (72) is installed horizontally at a certain distance from the rotor (72a).

[0064] The housing (72c) constituting the above cavitation generating means (72) accommodates a rotor (72a) and a stator (72b) inside, and a through hole is formed in the direction of the rotor (72a).

[0065] The discharge member (72d) constituting the above cavitation generating means (72) is formed so that water flowing into the gap (T) between the rotor (72a) and the stator (72b) is discharged toward one side of the rim of the housing (72c) or toward the other side of the housing (72c).

[0066] The UV-C LEDs (72e) constituting the above cavitation generating means (72) are installed in multiple numbers at regular intervals in the direction of the arc on one side edge of the housing (72c).

[0067] At this time, the UV-C LED (72e) is electrically connected to a separate power supply means and functions to irradiate UV-C ultraviolet rays of a certain wavelength range.

[0068] Meanwhile, as shown in FIG. 3, the water inlet (73) constituting the cavitation unit (70) of the present invention is connected to the rear end of the cavitation generating means (72), and one or more inlets through which the water is introduced are connected to the cavitation generating means (72).

[0069] In addition, the impeller part (74) constituting the cavitation unit (70) of the present invention is rotatably coupled to the rotation shaft (71b), as shown in FIG. 4, and is provided so that water introduced into the water inlet part (73) is pumped through the rotational force of the blade.

[0070] The cavitation unit (70) including the above-described configurations comprises a rotor (72a) that is rotated strongly by a driving motor of a driving shaft rotating part (71) and a stator (72b) that is provided facing the rotor (72a) and spaced apart from the rotor by a certain distance, and water flows into the gap (T) formed between them, and then shearing and cavitation occur quickly due to the strong rotational force of the rotor (72a), thereby causing a rapid reaction by increasing the surface area as well as micro-splitting of water molecules.

[0071] That is, as a result of water treatment (H2O2+UVC+CAVITATION) by the above cavitation unit (70), the water can be sterilized by the strong sterilizing power according to the advanced oxidation process (AOP).

[0072] Meanwhile, according to an embodiment of the present invention, the second clutch (80) is provided inside the engine (1) and is configured to allow or release the operation of the pump (51) by the driving force of the engine (1) with respect to the cavitation unit (70).

[0073] According to an embodiment of the present invention, the drinking water storage tank (90) is configured to store water discharged through the cavitation unit (70) and utilize the drinking water stored in the drinking water storage tank (90) when necessary.

[0074] Meanwhile, according to an embodiment of the present invention, as shown in FIG. 1, the control unit (100) is equipped with a control timer (101) that controls whether the first clutch (30) or the second clutch (80) operates at a preset time.

[0075] For example, the control unit (100) can control the other clutch to stop its function when one of the clutches, the first clutch (30) that functions to allow transmission of output by the driving force of the engine (1) or the second clutch (80) that functions to allow operation of the pump (51) by the driving force of the engine (1), is in a functioning state.

[0076] As another example, in the case of the above control timer (101), the second clutch (80) may be operated during the day to supply drinking water, and the first clutch (30) may be operated at night to supply power generated by the output of the engine (1) to each receiving location or store it in the ESS battery (21).

[0077] According to an additional embodiment of the present invention, a power measurement unit (120) connected to the drive control unit (40) to measure the amount of power generated by the generator (20) and the amount of power stored or discharged in the ESS battery (21) may be further included.

[0078] The present invention further includes the power measurement unit (120), so that the control unit (100) can transmit a control signal to the generator (20) according to the amount of power generated by the generator (20) and / or the amount of power stored or discharged in the ESS battery (21), and then perform a switch operation so that the generator (20) or the ESS battery (21) is selectively controlled.

[0079] Meanwhile, FIG. 2 is a flow chart for an engine power generation combined cavitation sterilization and disinfection system according to the present invention. Referring to FIG. 2, the engine power generation combined cavitation sterilization and disinfection system of the present invention first measures the energy stored in the ESS battery (21), and if the measured energy exceeds the required standard amount, the system is shut down, and conversely, if the measured energy is less than the required standard amount, the generator is started.

[0080] Next, after the generator (20) is operated, the power produced by the generator (20) is stored in the ESS battery (21).

[0081] At this time, some of the power produced by the generator (20) can be provided to each receiving location as needed (case 1).

[0082] In addition, the energy stored in the ESS battery (21) can be converted into electricity and the converted electricity can be provided to each receiving location as needed (case 2).

[0083] Next, the energy stored in the ESS battery (21) is measured a second time, and if the measured energy is less than the required standard amount, the process returns to the first measurement process and the above-described processes are repeated. Conversely, if the measured energy exceeds the required standard amount, the generator (20) is stopped and the overall operation of the system is halted.

[0084] To summarize the above, the present invention enables more efficient use of electric energy by selectively operating power supply and sterilized drinking water supply according to day / night or set time periods through continuous operation.

[0085] In addition, the powerful sterilizing power of the Advanced Oxidation Process (AOP) can maximize the efficiency of sterilization and disinfection of raw water, and it can be widely used in remote areas, military areas, and other places at home and abroad where the supply of drinking water is difficult due to regional characteristics.

[0086] As described above, the engine power generation combined cavitation sterilization and disinfection system according to the present invention has been described by way of example only, and is not intended to limit the scope of the invention. Furthermore, it will be apparent to those skilled in the art that various modifications and imitations are possible without departing from the spirit and scope of the invention.
