[0096] Hereinafter, the implementation of the ultrasonic liquid treatment device of the present invention will be described. This implementation shows a preferred mode of the ultrasonic liquid treatment device, but the present invention is not limited thereto. The liquid to be treated is drinking water, edible liquid, liquid medicine, coolant, cleaning liquid, biological liquid, seawater, river water, lake water, rainwater, tap water, etc.

[0097] (Ultrasonic unit)

[0098] Regarding the ultrasonic unit 10 of this implementation, based on Figures 1 to 3 it will be described. The ultrasonic unit 10 is driven by an ultrasonic transmitter 30.

[0099] In Figure 1 the implementation, the ultrasonic unit 10 includes a filter membrane 11 and an ultrasonic vibrator 12, and the filter membrane 11 and the ultrasonic vibrator 12 are separate components. This separate configuration only requires that the filter membrane 11 and the ultrasonic vibrator 12 are different objects. The arrangement structure can also be a configuration in which the filter membrane 11 and the ultrasonic vibrator 12 are arranged in contact with each other or arranged at a specified interval.

[0100] In this implementation, the liquid is transported by the ultrasonic vibration of the ultrasonic vibrator 12, and the filter membrane 11 filters the liquid for treatment.

[0101] In Figure 2 the implementation, the ultrasonic unit 10 includes a filter membrane 11 and an ultrasonic vibrator 12, and the filter membrane 11 and the ultrasonic vibrator 12 are integrated components. This integrated configuration can also be achieved by coating the filter membrane 11 to be integrated with the ultrasonic vibrator 12 or bonding the filter membrane 11 to be integrated with the ultrasonic vibrator 12, and the integrated structure is not particularly limited.

[0102] In this embodiment, through the ultrasonic vibration of the ultrasonic oscillator 12, the filter membrane 11 vibrates integrally to convey the liquid and perform filtration for treatment.

[0103] In Figure 3 the embodiment, the ultrasonic unit 10 is composed of the ultrasonic oscillator 12, and the ultrasonic oscillator 12 forms the structure of the membrane. This structure does not use a filter membrane but only the ultrasonic oscillator 12.

[0104] In this embodiment, through the ultrasonic vibration of the ultrasonic oscillator 12, the liquid is conveyed only by the ultrasonic oscillator 12 and filtration is performed for treatment.

[0105] [Filter membrane]

[0106] The filter membrane 11 is formed, for example, by molding a synthetic resin, and the synthetic resin may include, for example, at least one of polycarbonate, polysulfone, polyester, polyethylene, and polypropylene. Although not particularly limited, a satisfactory material is selected according to the liquid to be treated.

[0107] [Ultrasonic oscillator]

[0108] The ultrasonic oscillator 12 can use, for example, a PZT oscillator and the PZT oscillator uses lead zirconate titanate (piezoelectric ceramic), or a BL oscillator such as a bolt-clamped Langevin type oscillator can be used. According to the use conditions, the oscillator can be directly arranged only, or a vibration plate made of metal or the like can be joined to the oscillator for arrangement, or a sound emitter called a horn made of metal or the like can be joined for arrangement. The ultrasonic oscillator can be in the shape of a plate, a rod, a cylinder, etc.

[0109] (Ultrasonic liquid treatment device)

[0110] Regarding the embodiment of the ultrasonic liquid treatment device 20, it will be described based on Figure 4 and Figure 5 be explained.

[0111] In Figure 4 the embodiment, the ultrasonic liquid treatment device 20 includes a treatment unit 21 for treating the liquid, an ultrasonic unit 10 arranged in the treatment unit 21, and an ultrasonic transmitter 30 for driving the ultrasonic unit 10. The ultrasonic unit 10 has a structure for filtering the liquid. The ultrasonic unit 10 conveys the liquid through the ultrasonic vibration of the ultrasonic oscillator 12 and performs filtration using the filter membrane 11 for treatment.

[0112] In this embodiment, the ultrasonic unit 10 uses Figure 1 the embodiment, but Figure 2 the embodiment can be used or Figure 3In the embodiment, through the ultrasonic vibration of the ultrasonic unit 10, the ultrasonic unit 10 can perform a filtration process through a liquid.

[0113] In Figure 5 In the embodiment, the ultrasonic liquid treatment device 20 includes a treatment unit 21 for treating a liquid, an ultrasonic unit 10 disposed in the treatment unit 21, an ultrasonic transmitter 30 for driving the ultrasonic unit 10, and a pressure applying unit 22 for applying a pressure in the direction of liquid flow. The ultrasonic unit 10 has a structure for filtering a liquid. In a state where a pressure is applied to the liquid by the pressure applying unit 22, the ultrasonic unit 10 conveys the liquid through the ultrasonic vibration of the ultrasonic vibrator 12, and performs a treatment by filtering using the filter membrane 11.

[0114] In this embodiment, the ultrasonic unit 10 uses Figure 1 the embodiment of Figure 2 but can use Figure 3 the embodiment of

[0115] (Effect of the ultrasonic liquid treatment device)

[0116] Figure 6 is a diagram for explaining the effect of the ultrasonic liquid treatment device 20. In Figure 6 In the comparative example (a) in, a filter membrane is disposed in the treatment unit, and the treatment is performed by filtering through the filter membrane. Contaminants or fillers adhere to the filter membrane, and the filter membrane becomes clogged, thereby reducing the liquid treatment amount.

[0117] In Figure 6 In the embodiment (b) in, an ultrasonic unit 10 is disposed in the treatment unit 21. The ultrasonic unit 10 is configured in the same manner as Figure 1 the embodiment of

[0118] This ultrasonic unit 10 separates contaminants and fillers from the filter membrane 11 or the ultrasonic vibrator 12 through the ultrasonic vibration of the ultrasonic vibrator 12, disperses them, and performs filtration, and can maintain the liquid treatment amount.

[0119] In Figure 6 In the embodiment (b) in, the ultrasonic unit 10 is configured in the same manner as Figure 1 the embodiment of Figure 2 but even if it is configured in the same manner as Figure 3 the embodiment of

[0120] (Example)

[0121] [Example 1]

[0122] Based on Figure 7 to illustrate Example 1. Figure 7 In (a) is the example, Figure 7 In (b) is the comparative example.

[0123] In the ultrasonic liquid treatment device of Example 1, the treatment part is a non-pressurized filtration tank. The ultrasonic unit is a filtration structure with a pore size of 0.001 μm to 100 μm for the filtration membrane, and the ultrasonic vibration is 20 KHz to 4 MHz. The liquids to be treated are coolant and sewage.

[0124] The ultrasonic unit includes a filtration membrane and an ultrasonic vibrator, and the filtration membrane and the ultrasonic vibrator are separate components.

[0125] In this Example 1, through the ultrasonic vibration of the ultrasonic vibrator, the liquid can be transported, and the filtration membrane filters the liquid for treatment. In the comparative example, since there is only a filtration membrane and no ultrasonic vibrator with ultrasonic vibration, the liquid cannot be transported and the filtration treatment is insufficient.

[0126] The ultrasonic unit is a filtration structure with a pore size of 0.001 μm to 100 μm for the filtration membrane, and the ultrasonic vibration is 20 KHz to 4 MHz. In the filtration treatment of coolant and sewage, problems such as the mixing of fine substances or the reduction of the treatment amount will not occur, and satisfactory filtration treatment can be carried out.

[0127] [Example 2]

[0128] Regarding Example 2, based on Figure 8 to explain. Figure 8 In (a) is the example, Figure 8 In (b) is the comparative example.

[0129] In the ultrasonic liquid treatment device of Example 2, the treatment part is a non-pressurized water purifier. The ultrasonic unit is a filtration structure with a pore size of 0.001 μm to 10 μm for the filtration membrane, and the ultrasonic vibration is 20 KHz to 4 MHz. The liquids to be treated are seawater, river water, lake water, rainwater, tap water and sewage, etc.

[0130] The ultrasonic unit includes a filtration membrane and an ultrasonic vibrator, and the filtration membrane and the ultrasonic vibrator are separate components.

[0131] In this Example 2, through the ultrasonic vibration of the ultrasonic vibrator, the filtration membrane can filter the liquid for treatment. In the comparative example, there is only a filtration membrane and no ultrasonic vibrator, so the filtration treatment is not sufficient.

[0132] The ultrasonic unit is a filtration structure with a pore size of 0.001 μm to 10 μm, and the ultrasonic vibration is 20 KHz to 4 MHz. In the filtration treatment of seawater, river water, lake water, rainwater, and sewage, problems such as the mixing of fine substances or a decrease in the treatment volume will not occur, and satisfactory filtration treatment can be carried out.

[0133] [Example 3]

[0134] Regarding Example 3, based on Figure 9 An explanation will be given. Figure 9 (a) in is the example, Figure 9 (b) in is the comparative example.

[0135] In the ultrasonic liquid treatment device of Example 3, the treatment unit is a solar water purifier. The ultrasonic unit is a filtration structure with a pore size of 0.001 μm to 10 μm, and the ultrasonic vibration is 20 KHz to 4 MHz. Water such as seawater, river water, lake water, rainwater, and sewage is treated as the liquid.

[0136] The ultrasonic unit includes a filter membrane and an ultrasonic oscillator, and the filter membrane and the ultrasonic oscillator are separate components. The ultrasonic oscillator is driven by an ultrasonic transmitter. The solar panel is connected to the ultrasonic transmitter to obtain power.

[0137] Utilize the power saving of ultrasonic waves in areas without power infrastructure or during disasters, etc., and drive the ultrasonic unit with sunlight to achieve water purification.

[0138] In this Example 3, through the ultrasonic vibration of the ultrasonic oscillator membrane, the filter membrane can filter the liquid for treatment. In the comparative example, since there is only a filter membrane without an ultrasonic oscillator, the filtration treatment is not sufficient.

[0139] The ultrasonic unit is a filtration structure with a pore size of 0.001 μm to 10 μm, and the ultrasonic vibration is 20 KHz to 4 MHz. In the filtration treatment of seawater, river water, lake water, rainwater, and sewage, problems such as the mixing of fine substances or a decrease in the treatment volume will not occur, and satisfactory filtration treatment can be carried out.

[0140] [Example 4]

[0141] Regarding Example 4, based on Figure 10 An explanation will be given. Figure 10 (a) in is the example, Figure 10 (b) in is the comparative example.

[0142] In the ultrasonic liquid treatment apparatus of Example 4, the treatment unit is a filtration container. The ultrasonic unit has a filtration structure with a pore size of 0.001 μm to 100 μm, and the ultrasonic vibration is 20 kHz to 4 MHz. Water such as seawater, river water, lake water, rainwater, and tap water is treated as the liquid.

[0143] The ultrasonic unit includes a filtration membrane and an ultrasonic oscillator, and the filtration membrane and the ultrasonic oscillator are separate components. A pump is used as the pressure application unit that applies pressure in the direction of liquid flow.

[0144] When the pressure of the pump is 2 MPa, the throughput of water passing through is 40 L / min. Additionally, when the pressure of the pump is 1 MPa, the throughput of water passing through is 20 L / min.

[0145] In this Example 4, through the ultrasonic vibration of the ultrasonic oscillator, the filtration membrane can filter the liquid for treatment. However, in the comparative example, since only the filtration membrane is used without an ultrasonic oscillator, even when the pressure of the pump is 2 MPa, the throughput of water passing through is 20 L / min, and the filtration treatment is not sufficient.

[0146] The ultrasonic unit has a filtration structure with a pore size of 0.001 μm to 100 μm, and the ultrasonic vibration is 20 kHz to 4 MHz. In the filtration treatment of seawater, river water, lake water, rainwater, tap water, etc., problems such as the mixing of fine substances or a decrease in throughput do not occur, and satisfactory filtration treatment can be performed.

[0147] [Example 5]

[0148] Regarding Example 5, an explanation is given based on Figure 11 as follows. Figure 11 The filtration container is configured as a multi-stage type. The filtration container is configured to be divided into multiple treatment chambers by arranging multiple ultrasonic units. In this example, the ultrasonic units are arranged at three locations to form three treatment chambers, but it is not limited to this, and multiple treatment chambers can be provided.

[0149] The multiple ultrasonic units are configured such that the pore size becomes smaller along the direction of liquid flow. In the case where the viscosity distribution of the treatment liquid is in a wide range, for example, the pore size of the coarse filtration ultrasonic is about 10 μm, the pore size of the precision filtration ultrasonic is about 0.1 μm, and the pore size of the ultrafiltration ultrasonic is about 0.001 μm. With such a configuration, efficient filtration and separation and recovery can be performed.

[0150] The multiple treatment chambers have a recovery path for recovering the filtered matter, and the separated and recovered liquid is recovered from this recovery path. The valve of the recovery path can be in a state of always being open, or can be configured to open and close during a certain period.

[0151] In this ultrasonic liquid treatment device, the treatment unit is a filtration container. The ultrasonic vibration of the ultrasonic unit is 20 KHz to 4 MHz. Seawater, river water, drinking water, edible liquids, liquid medicines, cleaning liquids, biofuels, etc. are treated as the liquid.

[0152] [Example 6]

[0153] Regarding Example 6, based on Figure 12 an explanation will be given. Figure 12 (a) in Figure 12 is the treatment state, and

[0154] (b) in

[0155] is the recovery state. In the ultrasonic liquid treatment device of Example 6, the treatment unit is a classification and concentration container. The ultrasonic unit has a filtration structure with a pore size of 0.1 μm to 100 μm, and the ultrasonic vibration is 20 KHz to 4 MHz. Drinking water, edible liquids, liquid medicines, coolant liquids, cleaning liquids, and biological liquids are treated as the liquid.

[0156] The ultrasonic unit includes a filtration membrane and an ultrasonic oscillator, and the filtration membrane and the ultrasonic oscillator are separate components. A pump is used as the pressure application unit that applies pressure in the direction of liquid flow. Figure 12 In this Example 4, the liquid is transported to the classification and concentration container by the pump. In the classification and concentration container, the filtration membrane filters the liquid through the ultrasonic vibration of the ultrasonic oscillator, and for the stock solution and the recovered material, a classification and concentration treatment is performed while preventing clogging (

[0157] (a) in Figure 12 ).

[0158] When the treatment is completed and the pump is stopped, the recovered material remains at the bottom of the classification and concentration container, and the valve is opened for recovery (

[0159] (b) in

[0160] The ultrasonic unit has a filtration structure with a pore size of 0.1 μm to 100 μm, and the ultrasonic vibration is 20 KHz to 4 MHz. In the classification and concentration treatment of drinking water, edible liquids, liquid medicines, coolant liquids, cleaning liquids, and biological liquids, problems such as mixing of fine substances or reduction in treatment volume do not occur, and a satisfactory classification and concentration treatment can be performed. Figure 13 an explanation will be given. Figure 13 (a) in Figure 13 is when the ultrasonic wave is turned off in the intermittent control of the ultrasonic vibration, and

[0161] The ultrasonic unit can perform intermittent control of ultrasonic vibration. The control unit performs intermittent control on the ultrasonic transmitter based on information from a timer, a pressure sensor for the processing liquid, a concentration sensor for the processing liquid, etc. Figure 13 In (a) of Figure 13 the ultrasonic wave is off,

[0162] In the case of wanting to concentrate to a certain concentration or wanting to backwash, intermittent control of ultrasonic vibration is performed based on information from a timer, a pressure sensor for the processing liquid, a concentration sensor for the processing liquid, etc., so that effective filtration, separation, and concentration can be performed.

[0163] The ultrasonic unit is a filtration structure with a pore size of 0.01 μm to 100 μm for the membrane. The ultrasonic vibration is 20 KHz to 4 MHz. In the classification and concentration processing of drinking water, edible liquids, pharmaceutical liquids, coolant liquids, cleaning liquids, and biological liquids, problems such as the mixing of fine substances or a reduction in the processing amount do not occur, and satisfactory classification and concentration processing can be performed.

[0164] [Example 8]

[0165] Regarding Example 8, based on Figure 14 it will be described. Figure 14 In (a) of Figure 14 is the example,

[0166] In the ultrasonic liquid treatment device of Example 8, the treatment unit is a filtration container. The ultrasonic unit is a filtration structure with a pore size of 0.001 μm to 100 μm for the membrane. The ultrasonic vibration is 20 KHz to 4 MHz. As the liquid, water such as drinking water, edible liquids, pharmaceutical liquids, coolant liquids, cleaning liquids, biological liquids, seawater, river water, lake water, rainwater, and sewage is treated.

[0167] The ultrasonic unit includes a filtration membrane and an ultrasonic vibrator membrane, and the filtration membrane and the ultrasonic vibrator membrane are separate components. A pump is used as the pressure - applying unit that applies pressure in the direction of liquid flow.

[0168] When the pressure of the pump is 0.2 MPa, the water - passing treatment amount is 20 L / min.

[0169] In this Example 8, through the ultrasonic vibration of the ultrasonic vibrator membrane, pollutants and fillers can always be separated and dispersed, and the filtration membrane will not be blocked and can filter the liquid for treatment. However, in the comparative example, since only the filtration membrane is used without the ultrasonic vibrator membrane, even when the pressure of the pump is 0.2 MPa, due to blockage, the water - passing treatment amount is 1 L / min, and the filtration treatment is not sufficient.

[0170] The ultrasonic unit is a filtration structure with a pore size of 0.001 μm to 100 μm, and the ultrasonic vibration is 20 KHz to 4 MHz. In the filtration treatment of drinking water, edible liquids, medicinal liquids, coolant liquids, cleaning liquids, biological liquids, seawater, river water, lake water, rainwater, and sewage, problems such as the mixing of fine substances or a decrease in the treatment volume do not occur, and satisfactory filtration treatment can be performed.

[0171] [Example 9]

[0172] Regarding Example 9, based on Figure 15 an explanation will be given. Figure 15 In (a) is the example, Figure 15 In (b) is the comparative example.

[0173] In the ultrasonic liquid treatment device of Example 9, the treatment section is a filtration container. The ultrasonic unit is cross-flow filtration, a filtration structure with a pore size of 0.001 μm to 1 μm, and the ultrasonic vibration is 20 KHz to 4 MHz. Water such as seawater, river water, lake water, rainwater, and sewage is treated as the liquid.

[0174] The ultrasonic unit includes a filtration membrane and an ultrasonic vibrator, and the filtration membrane and the ultrasonic vibrator are separate components. A pump is used as the pressure application unit that applies pressure in the direction of liquid flow.

[0175] At a pump pressure of 0.2 MPa, the concentrated liquid is 1 L / min, and the treated liquid is 10 L / min.

[0176] In this Example 9, through the ultrasonic vibration of the ultrasonic vibrator, the treated liquid can be increased and the concentrated liquid can be decreased. However, in the comparative example, since the treated liquid is only 1 L / min, a large amount of concentrated liquid is required to obtain the specified treated liquid.

[0177] The ultrasonic unit is a filtration structure with a pore size of 0.001 μm to 1 μm, and the ultrasonic vibration is 20 KHz to 4 MHz. In the filtration treatment of seawater, river water, lake water, rainwater, and sewage, problems such as the mixing of fine substances or a decrease in the treatment volume do not occur, and satisfactory filtration treatment can be performed.
