Production apparatus of rotation and reverse rotation vortex type emulsion

The present invention relates to an emulsified oil production apparatus that does not use an emulsifier, and more particularly, to two or more rotating plates facing each other in order to continuously mix liquids that are not chemically mixed with each other, such as fuel oil and water. To increase the relative speed, and to interlock the blade structure of the rotating plate in the circumferential shape to form a strong vortex and collision, and to maintain the optimum emulsification state by measuring the mixing ratio of the emulsion oil passed through the mixing device by applying the dielectric constant measurement The present invention relates to a forward rotation and a reverse rotation vortex emulsion oil production apparatus.

Generally, emulsion oil is a liquid mixture made by mixing two or more kinds of insoluble liquids, as is well known, and in the present invention, various forms such as light oil, heavy oil, asphalt oil, and other liquids. Refers to a liquid mixture in which a second fluid, which is a liquid of, and a first fluid, such as water, which is not chemically mixed with the second fluid, are physically mixed and dispersed to remain in an emulsion oil state.

Emulsified oil mixed with two liquids that are not chemically mixed with each other is used in various industrial fields. For example, emulsified oils in which the fuel is mixed with water are much more beneficial in terms of energy and environment than those used alone. Accordingly, the Ministry of Environment has notified the performance standards and inspection methods of the air pollution prevention facilities (combustion aids) (Environmental Notice No. 2001-35) and recommends the use of emulsion fuel oil. In particular, emulsified oil fuel oil, which is highly viscous than petroleum oil (bunker C oil) with water and emulsified oil, has much greater energy efficiency and pollution prevention than heavy oil alone.

On the other hand, the following are known as apparatuses for producing emulsions of water and fuels.

① A device for mixing fuel, water and surfactants in a high speed mixer.

② Apparatus for supplying mixed liquid mixed by rotation by applying rotational force to fuel, water and surfactant.

(3) After mixing fuel, water, and surfactant using a mixer, etc., the mixed liquid is sprayed into a cylindrical body by a liquid acceleration nozzle, and the mixed liquid is collided with the impingement wall, thereby minimizing the particles of the mixed liquid ( And an apparatus for stirring the mixed liquid again using a stirring rotor or stator.

However, the first and second types of emulsified oil manufacturing apparatus are intended to mix fuel, water and surfactant by mixing fuel, water and surfactant with a mixer or by applying rotational force to the liquid, but the rotational force alone is used for fuel, water and Since the surfactant is not sufficiently mixed, the emulsified oil thus prepared has a problem of poor stability, not easy storage, and separation of fuel and water during storage.

On the other hand, since the third type of emulsion production apparatus takes time to manufacture the emulsion oil, it is not only necessary to store a tank for storing the emulsion oil, but also has a problem in economical efficiency because the entire apparatus becomes large. .

In order to solve such problems of the conventional emulsion oil production apparatus, an emulsion oil production apparatus as disclosed in Patent Publication No. 2002-40573 has been proposed. The present invention is an emulsification in which a mixing means for mixing liquids, a boosting pump for boosting the mixed liquid produced by the mixing means, and a plurality of compartments partitioned by the partition walls and three small holes communicating with the compartments adjacent to the partition walls are formed. A means, in which the mixed liquid pressurized by the boosting pump to the emulsifying means is ejected at a high pressure from the small holes of the partition wall so that fluid friction occurs, whereby the particles of the mixed liquid are made fine and a stable oil emulsion oil of high quality is obtained. It is.

The emulsified oil made by the apparatus as described above increases the use efficiency of the second fluid. When the second fluid is a fuel, emulsifying with the first fluid such as water not only increases energy efficiency but also reduces the emission of environmental pollutants.

For this effect, a method of mixing water with petroleum and combusting is disclosed in Korean Patent Publication No. 2002-17965. The present invention is a device for producing emulsion oil fuel oil by dispersing water in a fine granular state in a mixture composed of fuel oil, water, and emulsifier introduced through the inlet pipe, wherein the emulsifier is 10 to 20 rod wings on the outer edge The rotor having the mesh and the size of the mesh was 30 to 50 mesh to engage the rotor with a cylindrical mesh screen integrally.

However, the former invention uses a plurality of devices to perform their respective functions, such as mixing means, boosting pumps, and emulsifying means, as can be seen from the above, so that the manufacturing cost increases, There was a problem that the installation area is required.

In addition, the latter invention is intended to make emulsified oil fuel oil using a mixture composed of fuel oil, water, and emulsifier, but in order to use heavy oil emulsified oil as fuel, transport and storage of the mixture as described above are required. . However, when the mixture is left for a long time in this process, an oil-water separation phenomenon occurs and there is a problem that it is very difficult to put this mixture into fuel.

On the other hand, in the case of using emulsified oil as fuel, the fuel consumption changes every time, so proportional control is performed to control a constant emulsion ratio. In general, for proportional control, a flow meter for measuring the consumption state of fuel oil and water consumption are measured. Has a water meter and adjusts the discharge amount of water with a pump such as a variable metering pump or an inverter according to a preset emulsion ratio to obtain a constant emulsion ratio.

In this case, since the flow meter, water meter, metering pump, etc. are composed of mechanical parts, there is a problem that maintenance is required regularly due to abrasion or blockage, and flow meter, water meter, variable metering pump and inverter required by proportional control. The backs are expensive parts and cannot be manufactured on a small scale, and there is a problem in that an emulsified oil manufacturing apparatus is complicated and large-scaled is inevitable by increasing the manufacturing cost.

The present invention is to solve the above problems, and is manufactured at a lower cost, while being installed in a smaller area, a plurality of liquids that are not chemically mixed with fuel oil and water or emulsifiers (surfactants), such as Are separated into very fine droplets and distributed to each other, and a forward and reverse vortex emulsion manufacturing apparatus for automatically acquiring an emulsion state and maintaining an optimum emulsion state by measuring the water content contained in the emulsion oil in real time. For the purpose of providing it.

In addition, it is another object of the present invention to enable feedback control to control precise emulsification ratio even if there is no flow meter, water meter, variable metering pump and inverter required for the proportional control system for measuring the consumption state of fuel oil.

An object of the present invention described above is an emulsion oil production apparatus, comprising: a mixer unit for mixing two liquids which are not chemically mixed by rotating two blades forward or reverse by a motor, and a capacitance caused by a change in dielectric constant.

The mixing device of the present invention described above is configured to rotate forward and reverse with each other to face the two rotating plates in order to implement high speed rotation, and to form a strong vortex and collision by engaging the blade structure of the rotating plate in a circumferential manner. It is characterized by.

As described above, according to the present invention, the emulsion oil has the effect of efficiently obtaining fine and homogenized emulsion oil particles in the forward and reverse rotation counter mixing plate, and can extend the life of the mixing device. .

In addition, there is an effect that can reduce the power drive ratio of the emulsion oil mixing device to 1/4 than the prior art.

In addition, feedback control by applying dielectric constant measurement has the effect of automatically obtaining the emulsified state and maintaining the optimum emulsified state by measuring the water content contained in the emulsified oil in real time.

In addition, the feedback control means constitutes both the detection and control means by electronic components so that the mechanical parts of the proportional control means are not used so that expensive components such as flow meters, water meters, variable metering pumps and inverters are worn or blocked.

In addition, the state of the emulsified oil can be controlled in parallel with the proportional control method or the feedback control or the proportional control and the feedback control can be precisely controlled.

Hereinafter, a preferred embodiment of the forward rotation and reverse rotation vortex emulsion oil production apparatus of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall configuration of the forward and reverse vortex emulsion oil production apparatus according to the present invention, Figure 2 is a partial three-dimensional view of the blade portion according to the present invention, Figure 3 is a mixing device and a drive motor according to the present invention 4 is an exploded cross-sectional view of the mixing device blade portion and the casing according to the present invention, and FIG. 5 is a schematic view of the controller 50 according to the present invention.

As shown in FIG. 1, the forward rotation and reverse rotation vortex emulsion production apparatus includes a mixing device unit 10 for mixing two liquids that are not chemically mixed by rotating two blades forward or reverse by a motor. )Wow; A capacitive sensor 20 for measuring the mixing ratio of the emulsified oil passing through the mixing device unit 10 by corresponding the change in capacitance caused by the change in dielectric constant with the oscillation frequency of the oscillator; An oscillator 30 configured to change the oscillation frequency according to the capacitance change of the capacitive sensor 20 by configuring a circuit such that a positive feedback is achieved by combining a resistor and a capacitor RC in a logic IC or an OP-AMP; A divider 40 for converting the frequency input from the oscillator 30 into 1 / n and dividing at a frequency of several hundred KHZ; Real-time measurement of water content in emulsified oil to obtain the emulsified state (e.g. emulsification ratio, temperature, controller setting status, failure history) Control unit 50 for communicating with the external device for; And an accumulator 70 positioned between the capacitive sensor 20 and the combustion engine to buffer a sudden change in the emulsion ratio.

As shown in FIGS. 2 and 3, the mixing device unit 10 is configured such that the two rotating plates 11 are circumferentially opposed to each other and are interlocked with each other to forward or reverse rotation.

That is, in the emulsification process, the two rotating plates 11 face each other in the forward or reverse rotation, so that their relative speeds are doubled so as to rotate at high speeds. A collision is formed.

Here, when the relative speed is doubled, the same relative rotational speed can be obtained even if the rotational speed of one rotating plate 11 is reduced by half. Usually, the frictional loss is inversely proportional to the square of the speed, so if the rotational speed is reduced to half, the motor The driving power of is reduced to one quarter, and the mechanical wear of the motor and mixer accessories is reduced, resulting in an increase in the lifespan of the bearings and the leak-tight seals.

As shown in FIG. 4, a plurality of holes and irregularities 12 are provided in the surface in which the two blades face each other and in the casing 14 and the bracket of the mixing device. At this time, the hole and the concave-convex 12 maximize the mixing capacity in the same principle as millstone.

Figure 10 is another embodiment of the blade of the present invention, the rotating plate 11 is configured to be opposed to each other in a circumferentially opposed to reverse rotation, the groove is formed long in the longitudinal direction on the surface facing the blade.

That is, in the emulsification process, the two rotating plates 11 rotate in opposite directions to each other to double the relative speed, thereby rotating at a high speed, and by forming a strong vortex and collision by interlocking the blade structures of the rotating plates 11 in a circumferential shape. do.

In the forward rotation and reverse rotation vortex emulsion production apparatus, the ultrasonic emulsion tank 80 which further atomizes the emulsion oil flowing out from the accumulator 70 by an ultrasonic vibrator and delivers it to the combustion device is the accumulator 70. And between the combustion engine.

The accumulator 70 is configured by incorporating a small stirrer to agitate the emulsion oil therein to maintain a uniform emulsion oil state.

Next, a detailed configuration of the control unit 50 according to the present invention will be described with reference to FIGS. 5 to 7.

The controller 50 includes a microcontroller 51 for outputting a control command for acquiring and displaying or stably operating the operation state and the failure signal of the emulsion oil production apparatus as shown in FIG. 5; An oil / water quantity measuring unit 52 which measures the amount of oil, water or emulsifier introduced into the mixing apparatus from the oil tank, the water or the emulsifier tank, respectively, by measuring the flow rate and the water meter to the microcontroller 51; A temperature detector 53 which measures the temperature of the capacitive sensor 20 and transmits the temperature to the microcontroller 51 to obtain an emulsification ratio with a capacitance value according to the temperature change; A gas detector 54 for measuring an amount of gas (eg, NOx, SOx, CO 2, O 2, fine dust, etc.) included in the exhaust gas and optimizing the combustion efficiency of the combustion engine to the micro controller 51; A tacho sensor 55 for inputting the output signal of the taco sensor attached to the shaft of the combustion engine to the microcontroller 51 so as to replace the flowmeter and control the electric valve or the pump in the microcontroller 51; A flow rate controller 56 for adjusting the opening amount of the electric valve installed in the water or the emulsifier supply pipe or the discharge amount of the pump when the mixing ratio of the emulsified oil is determined in the microcontroller 51; A control signal output unit 57 for outputting an operation signal to an air supply inverter or various driving apparatuses and a pre heater; A control signal input unit 58 for transmitting an operation state or a failure signal of the burner or the combustion engine to the microcontroller 51; A key operation unit for controlling the emulsion ratio and the microcontroller 51 of the emulsion oil production apparatus; A display unit 59 for displaying an operation state (eg, an emulsion ratio, a temperature, a setting state of the microcontroller 51, a failure history in case of failure) of the emulsion oil production apparatus; And a communication unit 60 communicating with an external device for remote monitoring control.

In the present invention, the oscillation method was used to measure the change in capacitance according to the change in dielectric constant. The oscillation unit 30 is constituted by a grounded oscillation circuit with less external influence, and the capacitive sensor 20 is also coaxial. It is composed of a structure that shields the external electrostatic induction.

Here, the oscillator is composed of a logic IC or OP-AMP, as shown in Figure 6, by combining a resistor and a capacitor (RC) in this circuit it is possible to easily obtain a square wave oscillator. In FIG. 6, R5 becomes a fixed value and C1 corresponds to the capacitive sensor 20 of the present invention.

In addition, since the oscillation frequency is changed according to the capacitance change of the capacitive sensor 20, the oscillator has a positive electrode plate (eg, a center conductor and a metal) of the capacitive sensor 20 so that oscillation is stable in the oscillation circuit. Insulate the cylinder directly.

On the other hand, since the capacitance value of the capacitive sensor 20 is about several hundreds (pF), the output frequency output from the oscillator is a few MHZ. Since the data processing speed of the microcontroller 51 is low to directly input this frequency to the microcontroller 51, the frequency input from the oscillator 30 is inevitably converted to 1 / n to convert a frequency of several hundred KHZ into the microcontroller 51. Circuit is required. To this end, in the present invention, the dispensing unit 40 is configured between the oscillation unit 30 and the microcontroller 51.

The oil and water measuring unit 52 is a means for measuring the amount of oil, water, emulsifiers, etc., which are liquids required in the process of producing an emulsified oil, to the mixing device unit 10. The proportional control system automatically measures these mixing ratios. In order to control, the consumption of oil is first measured by a flow meter and transmitted to the microcontroller 51, and the microcontroller 51 controls an electric valve or a pump necessary for water control according to a pre-input mixing ratio, and controls the amount of emulsifier outflow. Takes information to control the electric valve or pump and the control signal is sent stepwise to maintain within ± 1 of the target value.

7 is a graph showing a change in capacitance value according to the amount of water added and temperature change per 100 g of oil.

Referring to FIG. 7, since the relative dielectric constant of the emulsion oil changes constantly according to the emulsion ratio and temperature, in the present invention, a table of the capacitance change according to the temperature and the emulsion ratio is stored in the storage device of the microcontroller 51. In addition, the capacitive sensor 20 and the temperature detector 53 receive the capacitance and the temperature, respectively, and compare with the stored table to predict what kind of emulsified oil is. Calculate the emulsion ratio. That is, if the temperature value and the capacitance value are known, the curve corresponding to the intersection of the X axis and the Y axis of FIG. 7 becomes the emulsification ratio of the emulsified oil.

On the other hand, the gas detection unit 54 detects the exhaust gas from the various gas detection sensors mounted on the combustion engine to optimize the combustion efficiency, and delivers the exhaust gas to the microcontroller 51, wherein the microcontroller 51 is connected to the exhaust gas. The amount of gas included (eg, NOx, SOx, CO2, O2, fine dust, etc.) is input to control the airflow amount, the emulsion ratio, and the fuel amount, and adjust the air supply amount.

The taco sensor 55 inputs the output signal of the taco sensor attached to the shaft of the combustion engine to the microcontroller 51 and the microcontroller 51 in proportion to the quantity (the fuel consumption in the combustion engine is the rotation of the engine). The flow rate adjusting device for adjusting the opening of the electric valve or adjusting the discharge amount of the pump by outputting a stepped signal and outputting a stepped signal to replace the flow meter corresponding to the object of the present invention. It is a means.

When the mixing ratio of the emulsified oil is determined in the microcontroller 51, the microcontroller 51 reads the capacitance value of the emulsified oil each time and outputs a control signal for adjusting the opening of the electric valve or adjusting the discharge amount of the pump according to the excess value and the insufficient value according to the target value. The control command to increase or decrease is sent to the flow rate controller 56 in a step by step manner.

Next, the mixing ratio measurement principle of the capacitive sensor 20 of the present invention will be described with reference to FIGS.

The present invention performs a function to automatically obtain the emulsified state and maintain the optimum emulsified state by measuring the water content contained in the emulsified oil in real time by feeding back to the control unit 50 through the capacitive sensor 20, the feedback control In order to measure the mixing ratio of the emulsion oil passed through the mixing device is required. In the present invention, the capacitance of the emulsified oil is measured by using the capacitive sensor 20 to correspond to the change in capacitance caused by the change in dielectric constant at the oscillation frequency of the generator.

The permittivity is a value that represents the electrical characteristics of a dielectric, that is, a non-conductor, and is directly related to the characteristics of alternating electromagnetic waves. It is a measure of how sensitive the + and-moments inside a material are aligned with the change of an external electromagnetic field. The relative dielectric constants are shown in the following table.

Dielectric type Relative dielectric constant Temperature (℃) Vacuum or dry air One water 88 0 water 80.4 20 water 80 26.7 DIESEL FUEL (via) 1.77 21.1 GASOLINE (petrol) 1.84 21.1 HEAVY OIL 3 HEAVY OIL C (C heavy oil) 2.6 KEROSENE (kerosene) 1.8 21.1

As shown in the table above, the relative dielectric constant of water is about 40 times that of petroleum. In other words, the relative dielectric constant of the emulsified oil increases with a large value depending on the amount of water contained in the petroleum.

The dielectric constant is determined by the polarization molecules of the material, and the higher the water content, the higher the dielectric constant. The higher the frequency, the lower the dielectric constant and closely related to the temperature.

8 is a cross-sectional view of a capacitive sensor according to the present invention.

As shown in FIG. 8, since the insulator (or dielectric) and the emulsified oil are in series between the center conductor and the metal cylinder, the capacitive sensor 20 is equivalent to the series capacitor when interpreted as capacitance.

Here, the composite capacitance of the capacitor is C0 = (C1 * C2) / (C1 + C2), so the material of C1 must be applied to an insulator such as ceramic with high dielectric constant, so that the C6's composite capacitance is dependent on the moisture state of the oil. Can make a big difference.

In the above formula, the C2 value is fixed and the combined capacity C0 when the value of C1 is changed is shown in the table below.

Composite capacitance according to dielectric constant C1 C2 C0 0.1 One 0.090909 One One 0.5 10 One 0.909091 100 One 0.990099 1000 One 0.999001

As can be seen from the table above, if the dielectric constant of C1 is more than 100, the influence of insulator C1 is less than 1% and can be ignored.

The relative dielectric constants of synthetic resins such as PVC are 2 to 3, and ceramics such as titanium oxide have materials ranging from thousands to tens of thousands of dielectric constants. However, as another method for reducing the influence of the insulator C1, if the thickness d of the insulator is made very thin, the C1 becomes relatively large, so the corresponding method is appropriate.

FIG. 9 is a graph of the above table in which the relative dielectric constant of the mixture is constant according to the mixing ratio, and in the case of the mixture, the dielectric polarization is different. In addition, the dielectric polarization of the dielectric changes with temperature.

The change of the experimental capacitance value when combining this is shown by the nonlinear curve as shown in FIG.

How each configuration of the present invention operates organically will be described in detail below.

First, the oil is introduced into the mixing device through the flow meter, the oil and water measuring unit 52 transfers the measured value of the flow meter to the microcontroller 51 and according to the mixing ratio previously input from the microcontroller 51 Through 56, the electric valve or pump of the water tank is controlled to introduce the necessary water into the mixing device.

The oil and water respectively enter the mixing device through the liquid outlet 13 and collide with the strong vortex while passing through the unevenness 12 between the two mixing wheels 11, which rotate forward or reverse with each other by the power of the motor. Are formed and mixed with each other.

Emulsified oil mixed in the mixing device is passed to the emulsion oil outlet and delivered to the capacitive sensor 20, the oscillator 30 changes the oscillation frequency according to the capacitance change of the capacitive sensor 20 Transmitting to the dispensing unit 40, the dispensing unit 40 converts the frequency input from the oscillation unit 30 to 1 / n and outputs to the microcontroller 51, the temperature detector 53 is a capacitive sensor The temperature of 20 is measured and output to the microcontroller 51.

Thereafter, the microcontroller 51 obtains the mixing ratio of the emulsified oil from the capacitance change table according to the temperature and the emulsification ratio recorded in the storage device as values input from the temperature detector 53 and the dispensing unit 40 to maintain the mixing ratio. By controlling the flow control device 56 to be able to control the amount of the solution introduced into the mixing device in real time.

That is, when the table related to the curve of the capacitance value due to the change of the dielectric constant according to the emulsion ratio and the temperature of the emulsion oil is input to the microcontroller 51 and the emulsion oil production apparatus is operated, only pure oil is passed through the mixing apparatus. The oil is passed through the capacitive sensor 20 installed between the emulsified oil mixing device and the combustion engine, and the oscillation frequency of the oscillation circuit is measured by the microcontroller 51 and stored in the memory. When predicting what kind of oil is compared with the above chart and transmitting the electric valve or pump driving signal based on the corresponding chart, the discharge signal is controlled by the step-by-step method so that the capacitance of the oil The value is read and the control signal of the electric valve or pump is increased or decreased as the value is over or under the target value.

At this time, if the oil consumption continuously changes smoothly, the emulsion ratio can also be controlled smoothly. However, when the abrupt decrease, the reaction rate of the control system is slow, and thus the quantity may be excessive. In order to overcome such a closed end, an accumulator 70 is provided at the rear end of the capacitive sensor 20 to buffer a sudden change in the emulsion ratio. The volume of the accumulator 70 is about 10 times larger than the volume of the liquid present in the mixing device so that the worst emulsification ratio is within 10%.

The accumulator 70 includes a small stirrer to stir the emulsion oil in the accumulator 70 to maintain a uniform emulsion oil state.

On the other hand, the amount of fuel consumed in the combustion engine through the accumulator 70 is measured by the taco sensor 55 attached to the shaft of the combustion engine and transmitted to the microcontroller 51, and the microcontroller 51 is connected thereto. The proportional quantity is calculated and controlled by a stepwise control of the electric valve or pump through the flow regulator 56.

In addition, the emulsified oil flowing out from the accumulator 70 is further pre-set by the ultrasonic vibrator of the ultrasonic emulsifying tank 80 to supply the emulsified oil to a combustion device or the like.

The operation state (eg, emulsion ratio, temperature, setting state of the microcontroller 51 and failure history in case of failure) of the oil production apparatus is output through the display unit 59 and transmitted to the remote place through the communication unit 60. do.

In the present invention, since the overflow flow rate is input back to the capacitive sensor 20 or the mixing device, the emulsion ratio of the emulsion oil can be continuously measured.
