Description

  The present invention relates to an emulsion fuel production apparatus and method suitable for preventing clogging of a fuel filter due to mold generated in emulsion fuel during the emulsion fuel production process.

  In recent years, in order to reduce the nitrogen oxide concentration (NOx) in exhaust gas, an emulsion fuel in which water and an emulsifier (neutralizing agent) are added to a fuel oil (heavy oil, kerosene, light oil, waste oil, etc.) and emulsified has been used. It is used (for example, refer to the following Patent Document 1).

FIG. 5 shows a conventional emulsion fuel production apparatus 110 for supplying emulsion fuel to the diesel engine 120.
The emulsion fuel production apparatus 110 includes a fuel oil supply apparatus 11, a flow meter 12 attached to the fuel oil pipe 13, a water injection tank unit 20, an emulsifier tank unit 30, and a mixed liquid supply attached to the emulsion fuel pipe 41. A pump 40, an emulsifying device 50 (line mixer), and a fuel filter 60 are provided.

  Here, the water injection tank unit 20 includes a water injection tank 21 for storing soft water (hereinafter referred to as “added water”) supplied from the soft water tank, an additive water supply pump 22 attached to the additive water pipe 24, and And an additive water flow rate adjustment valve 23.

  The emulsifier tank unit 30 includes an emulsifier tank 31 in which the added emulsifier is stored, an added emulsifier supply pump 32 and an added emulsifier flow rate adjustment valve 33 attached to the added emulsifier pipe 34.

The added water flow rate adjusting valve 23 and the added emulsifier flow rate adjusting valve 33 adjust the flow rates of the added water and the added emulsifier flowing through the added water piping 24 and the added emulsifier piping 34 according to the flow rate of the fuel oil measured by the flow meter 12. Thus, the water addition rate and the emulsifier addition rate are maintained at predetermined values.
The added water supply pump 22, the added water flow rate adjustment valve 23, the added emulsifier supply pump 32, and the added emulsifier flow rate adjustment valve 33 are started and stopped in response to a start / stop command input from the outside.

The fuel oil pipe 13, the added water pipe 24 and the added emulsifier pipe 34 are connected to the emulsion fuel pipe 41, and the added water and the added emulsifier whose flow rates are adjusted by the fuel oil and added water flow rate adjustment valve 23 from the fuel supply device 11. The added emulsifier whose flow rate is adjusted by the flow rate adjusting valve 33 is mixed and supplied to the emulsifying device 50 via the mixed liquid supply pump 40.
At this time, the return oil pipe 71 is also connected to the emulsion fuel pipe 41, and the fuel return oil returned from the diesel engine 120 via the return chamber 130 to the emulsion fuel production apparatus 110 is also mixed with the fuel oil, added water, and added emulsifier. Then, it is supplied to the emulsification device 50 via the mixed liquid supply pump 40.

  The emulsifying device 50 includes a guide vane installed on the inlet side in the pipe constituting the emulsifying device 50, and a protrusion (current cutter) installed on the inner wall of the pipe on the outlet side of the guide vane. After the swirling flow of the mixed liquid of oil, added water, added emulsifier and fuel return oil is generated by the guide vane, the mixed liquid is mechanically stirred at the protrusions to emulsify the fuel oil, thereby generating an emulsion fuel. .

As shown in FIG. 6A, the fuel filter 60 (automatic backwash filter) takes a mixed liquid from an outer peripheral surface into a cylindrical main body 61 having an oil collection pipe 63 (collection pipe) at the center. 24 cylindrical filters 62 for filtering with a filter medium are provided.
Here, about 24 filters 62 are arranged on the inner side and about 18 on the outer side so as to surround the oil collecting pipe 63 doubly.

  In the emulsion fuel production process using the emulsion production apparatus 110, when mold fungus (soil fungus) is contained in the fuel oil or the added water, the generation of mold is promoted, and the mixture of the fuel oil and the added water is used. Mold is easily generated when heat is applied.

When heavy fuel oil A is used as fuel oil, it is not necessary to forcibly heat heavy fuel oil A, but a circulation circuit in which fuel return oil from diesel engine 120 is returned to emulsion production apparatus 110 via return chamber 130 As a result, the A heavy oil is slightly heated by the heat radiation from the diesel engine 120. As a result, mold is easily generated in the emulsion fuel.
Further, in general, B heavy oil is forcibly heated at 70 ° C. or higher and C heavy oil is forcibly heated to 100 ° C. or higher. Therefore, when B heavy oil or C heavy oil is used as fuel oil, A heavy oil is used. Mold is more likely to occur than when using.

Mold generated in the emulsion fuel propagates using the fuel oil as a nutrient at the interface between the finely mixed fuel oil and the added water.
Further, depending on the emulsion fuel, the emulsion fuels are combined to form a large combined body (scum) to increase the viscosity, thereby increasing the viscosity of the fuel oil pipe 13, the addition water pipe 24, the inner wall of the emulsion fuel pipe 41, and the fuel filter 60. Since it adheres to the outer peripheral surface of the filter 62, mold is generated in the attached bonded body and propagates.

The following Patent Document 2 discloses a coil portion for irradiating a fluid to be processed, a reduction (−) modulation electromagnetic field generator for passing a square-wave alternating current whose frequency changes with time in the coil portion, and a coil portion. Between the two modulated electromagnetic field generators and the coil section, and an oxidation (+) type modulated electromagnetic field generator that intermittently passes an alternating current with a sine wave on a square wave whose frequency changes with time. A modulation electromagnetic field processing device is disclosed that includes a switch for operating one of the two modulation electromagnetic field generators.
Further, as such a modulated electromagnetic field processing apparatus, a water watcher (registered trademark) manufactured by SK Corporation has been commercialized.

  However, in the conventional emulsion fuel production apparatus 110, when mold generated in the emulsion fuel adheres to the outer peripheral surface of each filter 62, clogging of the fuel filter 60 (clogging of each filter 62) occurs (FIG. 6 (FIG. 6)). b))), an antifungal agent (chemical) is added to the emulsion fuel to suppress the growth of fungi or to inhibit the fungal growth that has already occurred and kill the fungi. Solutions other than drugs are required.

  Further, the modulation electromagnetic field processing device disclosed in Patent Document 2 described above uses an oxidation (+) type modulation electromagnetic field generator and a reduction (−) type modulation electromagnetic field generator in combination, and switches them to modulate at the coil unit. Prevents and removes scale from the flow path or storage tank wall using any fluid to be processed (water to be processed), prevents corrosion of any flow path or storage tank wall, oil by electromagnetic field treatment by an electromagnetic field generating device Prevents clogging of the wastewater flow path, deodorization of ammonia odor from ammonia-containing water, prevention of clogging of the filter for filtering the water to be treated, prevention of adhesion of marine organisms to the water flow path or storage tank wall Although it is known that it can be obtained (see paragraph 0049 of the publication), it is unclear whether it is effective in preventing clogging of the fuel filter due to mold generated in the emulsion fuel.

  The above object has been realized by applying a high-frequency plus-type modulated electromagnetic field from the oxidized modulated electromagnetic field generator to the fuel oil pipe and the additive water pipe.

Embodiments of an emulsion fuel production apparatus and method according to the present invention will be described below with reference to the drawings.
As shown in FIG. 1, an emulsion fuel production apparatus 1 according to an embodiment of the present invention includes an oxidation-type modulated electromagnetic field generator 2 having a fuel oil piping coil 2a and an additive water piping coil 2b, and a fuel oil piping coil. 2a is wound around a portion downstream of the flow meter 12 of the fuel oil pipe 13 (a part on the mixed liquid supply pump 40 side), and the additive water pipe coil 2b is connected to a downstream part (a part on the side of the mixed liquid supply pump 40) of the additive water pipe 24. ) Is different from the conventional emulsion fuel production apparatus 110 shown in FIG.

Here, the oxidation-type modulated electromagnetic field generator 2 continuously or intermittently applies a modulated electromagnetic field signal in which a sine wave is superimposed on a high-frequency (for example, 40,000 Hz) square wave to the fuel oil piping coil 2a and the additive water piping coil 2b. The high-frequency modulated electromagnetic field (hereinafter referred to as “plus-type modulated electromagnetic field”) is applied to the fuel oil pipe 13 and the additive water pipe 24 continuously or intermittently. It has a configuration similar to that of an oxidation (+) modulation electromagnetic field generator (for example, a frequency divider for converting a signal from an oscillator (OSC) into a signal of an arbitrary frequency, and an output signal of the frequency divider are input. And a generator for generating a modulated electromagnetic field signal and a power amplifier for amplifying the power of the output signal of the generator.
Therefore, an oxidation (+) modulation electromagnetic field generator included in the water watcher can be used as the oxidation modulation electromagnetic field generator 2.
The fuel oil piping coil 2a and the additive water piping coil 2b are connected in series.

  In the emulsion fuel production apparatus 1, the fuel oil from the fuel oil supply apparatus 11 includes added water from the water injection tank 21, added emulsifier from the emulsifier tank 31, and fuel return oil that returns from the diesel engine 120 via the return chamber 130. And is made into emulsion fuel by the emulsification device 50, and then supplied to the diesel engine 120 through the fuel filter 60.

  At this time, a plus-type modulated electromagnetic field is applied to the fuel oil pipe 13 and the added water pipe 24 from the oxidation-type modulated electromagnetic field generator 2 via the fuel oil pipe coil 2a and the added water pipe coil 2b.

Next, experimental results confirming that clogging of the fuel filter 60 can be prevented by using the emulsion fuel production apparatus 1 according to this embodiment will be described with reference to FIGS. 2 (a), 2 (b), and FIGS. This will be described with reference to h).
In addition, using an oxidation (+) type modulation electromagnetic field generator provided in the water watcher as the oxidation type modulation electromagnetic field generator 2, a positive modulation electromagnetic field of 40,000 Hz is continuously applied to the fuel oil pipe 13 and the additive water pipe 24. did.
In addition, using heavy fuel oil A as fuel oil, the emulsion fuel is sampled from the middle of the emulsion fuel pipe 41 connecting the fuel filter 60 and the diesel engine 120 every 15 minutes immediately after applying the plus-type modulated electromagnetic field, and the emulsified state is confirmed. did.
Furthermore, the water addition rate is normally set to 20% and the emulsifier addition rate is set to 2% so that the fuel oil and the added water are mixed well. In this case, the liquid mixture of the heavy oil A, the added water and the added emulsifier is used. Becomes a cloudy color and is stable without separation over time (see FIG. 2 (a)), so that the emulsifier addition rate = 1%, so that A heavy oil is separated from the added water and the added emulsifier immediately after sampling. (See FIG. 2 (b)).

In the emulsion fuel sampled immediately after the application of the plus-type modulated electromagnetic field of 40,000 Hz, A heavy oil (fuel oil) was separated from the added water and the added emulsifier as shown in FIG.
Similarly, even in the case of the emulsion fuel sampled 15 minutes, 30 minutes and 45 minutes after application of the 40,000 Hz plus-type modulated electromagnetic field, as shown in FIGS. ) Separated from added water and added emulsifier.

However, in the emulsion fuel sampled 60 minutes, 75 minutes and 90 minutes after application of the 40,000 Hz plus-type modulated electromagnetic field, as shown in FIGS. 3 (e) to 3 (g), A heavy oil (fuel oil) Did not separate from the added water and added emulsifier and the hue turned gray.
The reason for this is that the fuel oil and the added water are vibrated by being charged with a positive potential by applying a 40,000 Hz positive modulation electromagnetic field to the fuel oil pipe 13 and the added water pipe 24. Mold attached to the water pipe 24, the emulsion fuel pipe 41, and each filter 62 of the fuel filter 60 is peeled off and mixed in the emulsion fuel, and the inner wall of the fuel oil pipe 13 and the emulsion fuel pipe 41 and the fuel filter 60 This seems to be because the combined body (scum) was prevented from adhering to each filter 62 and the repulsive action between the emulsion fuels was also used to prevent the combined body from growing.

In the emulsion fuel sampled 105 minutes after the application of the 40,000 Hz plus-type modulated electromagnetic field, A heavy oil (fuel oil) was separated from the added water and the added emulsifier as shown in FIG.
The reason for this is that mold attached to the inner wall of the fuel oil pipe 13, the additive water pipe 24 and the emulsion fuel pipe 41 and the filter 62 of the fuel filter 60 is eliminated, and mold is not mixed into the emulsion fuel. It is.

Next, a comparison experiment result when the combination of the polarities of the modulated electromagnetic field applied to the fuel oil pipe 13 and the added water pipe 24 is changed using a water watcher instead of the oxidized modulated electromagnetic field generator 2 is shown in FIG. ) To (c).

A modulated electromagnetic field generated by continuously or intermittently flowing through a coil (hereinafter referred to as a “minus-type modulated electromagnetic field”) is applied to the fuel oil pipe 13, and an oxidized (+) modulated electromagnetic field generated by the water watcher is generated. When the additive water piping coil 2b is connected to the container and a 40,000 Hz plus-type modulated electromagnetic field is applied to the additive water piping 24, all of the emulsion fuel sampled from immediately after the application to 105 minutes later, Oil) separated from the added water and added emulsifier (see FIG. 4 (a)).

(Comparative experiment 2)
The fuel oil piping coil 2a and the additive water piping coil 2b are connected to a reduced (−) modulation electromagnetic field generator provided in the water watcher, and a negative modulation electromagnetic field of 40,000 Hz is applied to the fuel oil piping 13 and the additive water piping 24. In some cases, in all of the emulsion fuel sampled from immediately after application until 105 minutes later, the A heavy oil (fuel oil) was separated from the added water and the added emulsifier (see FIG. 4B).

(Comparative Experiment 3)
The fuel oil piping coil 2a is connected to the oxidation type (+) modulation electromagnetic field generator provided in the water watcher, and a positive type modulation electromagnetic field of 40,000 Hz is applied to the fuel oil piping 13 and the reduction type (−) modulation provided in the water watcher. Even when the additive water piping coil 2b is connected to the electromagnetic field generator and a negative modulation electromagnetic field of 40,000 Hz is applied to the additive water piping coil 2b, A Heavy oil (fuel oil) was separated from the added water and the added emulsifier (see FIG. 4C).

  In the above description, the oxidized modulation electromagnetic field generator 2 provided with the fuel oil piping coil 2a and the additive water piping coil 2b is used to wrap the fuel oil piping 13 downstream of the flow meter 12 and add the additive water piping coil. 2b is wound on the downstream side of the additive water pipe 24, but an oxidation-type modulated electromagnetic field generator (oxidation-type modulated electromagnetic field generator having one emulsion fuel pipe coil instead of the fuel oil pipe coil 2a and the additive water pipe coil 2b). 2), the emulsion fuel pipe coil is attached upstream (on the flow meter 12 side) of the emulsion fuel pipe 41 to the return oil pipe 71 to generate this oxidation-type modulated electromagnetic field. Even if a plus-type modulated electromagnetic field is applied to the emulsion fuel pipe 41 from the apparatus, the inner wall of the emulsion fuel pipe 41 and the fuel filter 6 It is possible to peel off the mold attached to, the same effect can be obtained.

  Similarly, the emulsion fuel piping coil of the oxidation type modulation electromagnetic field generator is attached to the downstream side (mixed liquid supply pump 40 side) of the connection point of the emulsion fuel piping 41 with the return oil piping 71, and this oxidation type modulation electromagnetic field is provided. Even if a plus-type modulated electromagnetic field is applied from the generator to the emulsion fuel pipe 41, mold attached to the inner wall of the emulsion fuel pipe 41 and the fuel filter 60 can be peeled off, and the same effect can be obtained.

  Further, a plus-type modulated electromagnetic field may be constantly applied from the oxidation-type modulated electromagnetic field generator 2 to the fuel oil pipe 13 and the added water pipe 24, and once the mold is removed, it adheres to each filter 62 of the fuel filter 60. Since it takes time to cause clogging, a plus-type modulated electromagnetic field is applied from the oxidation-type modulated electromagnetic field generator 2 to the fuel oil pipe 13 and the added water pipe 24 only when the emulsion fuel production apparatus 1 is regularly checked, for example. You may do it.
