Description

[Detailed Description of the Invention] The present invention relates to a heavy oil emulsifier that adds water to oil such as heavy oil, continuously emulsifies the oil, and supplies the emulsified oil to a combustion system.

With the rise in oil prices, a method of co-firing oil such as heavy oil by adding water and an emulsifier has been developed and is attracting attention.

The technology for emulsifying oil such as heavy oil and water has not yet been established.

This is because even if heavy oil is once emulsified, if it is left unattended or stored in a storage tank, it will gradually separate into heavy oil and water components, which will eventually result in the heavy oil being burned. .

For this reason, some devices are equipped with a stirring means in the storage tank for stirring, but the problem is that although the emulsified state is maintained near the stirring means, the heavy oil component and water component gradually separate in the farthest areas. Ta.

In addition, a pipe mixer is used in which twisted fins for forming turbulent flow are provided in a pipe, and heavy oil, water, etc. are flowed through the pipe at high speed to emulsify the mixture.

This is sufficient to emulsify to some extent, but some of the newly supplied heavy oil, water, etc. flows directly into the combustion system, and as a result, the emulsification state is insufficient, especially when heavy oil is preheated just before the nozzle. There is also the problem of separation into components and water components.

Therefore, the purpose of the present invention is to provide a heavy oil emulsifier that can completely emulsify heavy oil and water and supply emulsified heavy oil to the combustion system, thereby significantly saving the amount of heavy oil used for combustion. That's what we're trying to offer.

According to the present invention, an 8-cylindrical casing, an inner cylinder disposed inside the casing with its upper and lower ends open, and an inner cylinder disposed in a lower position of the inner cylinder in the casing in a direction parallel to the fluid flow direction. a first emulsifying means comprising rotary blades for propelling the fluid to be displaced in an angular range extending from the direction perpendicular to the first emulsifying means, and a driving means for rotationally driving these blades; A fin-formed pipe for emulsifying the water-temperature hardware is connected to a second emulsifying means arranged in a fluid circulation circuit, and heavy oil, water, and an emulsifier are supplied to the first emulsifying means at a desired mixing ratio; These are emulsified by the shearing and propulsion action of the rotating blade, and the emulsified heavy oil is circulated through the fluid passages inside and outside the inner cylinder to produce more stable emulsified heavy oil, and the sufficiently stable emulsified fluid is transferred to the next second stage.
The above purpose can be distantly achieved by supplying the fluid to an emulsifying means to more uniformly emulsify the fluid, circulating a portion to maintain the emulsified state, and supplying a portion to another combustion system. .

In order to adapt to the properties of the oil or the amount supplied to the combustion system, it is preferable that the inner cylinder of the first emulsifying means be configured to be able to slide vertically within the casing to adjust the height of the inner cylinder within the casing. It is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The heavy oil emulsification apparatus according to the present invention will be described in detail below with reference to preferred embodiments shown in the accompanying drawings.

FIG. 1 shows a flowchart of the heavy oil emulsification apparatus of the present invention.

Oil such as heavy oil is supplied from tank O through pipe 1, water is supplied from water tank W through pipe 2, pump 3 and pipe 4 to first emulsifying means 5, and emulsifier (Bionics Company trademark) is supplied from tank It is also supplied to the first emulsifying means 5 by the microinjection pump 7 via the micro-injection pump 7.

The mixing ratio of heavy oil, water and emulsifier (bionics) is
It has been confirmed through experiments that the content can be 70-85% by weight of heavy oil, 15-30% by weight of water, and about 0.2% by weight of emulsifier.

The mixing ratio can be adjusted appropriately by adjusting the capacity of the pump, valves, etc.

The first emulsifying means 5 has a double-tube structure in which an inner cylinder 9 is disposed in a cylindrical casing 8 with its upper and lower ends open.
A rotary blade 11 driven by a motor 10 for emulsifying and propelling fluid is provided below the inner cylinder, and heavy oil, water, and an emulsifier are charged into the casing 2 through a pipe 4, emulsified, and then discharged. It is configured to be supplied to the next second emulsifying means 14 via a pipe 12 and a valve 13.

Preferably, the fluid level is detected by a flow switch 15 to operate the motor 10.

In this first emulsifying means, the weight is the casing 8
An inner cylinder 9 is provided to form a fluid passage, and the fluid is sheared and propelled by the blades 11.

Therefore, it is preferable that the blade 11 be provided at a position below the inner cylinder 9, and that the shapes of the blades be appropriately combined as shown in FIG. 2.

The blade of FIG. 2a has an upwardly directed portion 16 at its distal end which serves to propel the fluid laterally, ie, at right angles to the direction of flow, toward the side of the inner cylinder.

The blade of FIG. 2b has a downwardly directed portion 17 at its distal end, which serves to propel the fluid downwardly, ie towards the bottom of the casing 8.

The blade of Figure 3C has a twist 18 at its distal end and serves to propel fluid in a direction intermediate the angle of thrust of blades 2a and 2C.

In addition, when the consumption of other systems is low or when the viscosity is too high and complete emulsification is difficult, the height of the inner cylinder 9 within the casing 8 can be lowered as shown in Figure 3. It is preferable that the fluid be emulsified in a shorter circulation cycle.

For adjusting the height of the inner cylinder, it is practically convenient to construct the inner cylinder with a plurality of cylindrical bodies so that they can slide telescopically.

As shown in FIG. 1, the second emulsifying device 14 forms a circulation circuit together with a pipe 19 provided with fins as described later, another ordinary pipe 20, a valve 21, and a pump 22. is delivered to the combustion system (nozzle or service tank) via pipe 23 and valve 24.

A typical configuration example of the pipe 19 is shown in FIG.

Twisted vanes 29 are disposed in the pipe 19 alternately with the orifice 28 and are spaced at an interval of 120°, and the vanes 29 are assembled and supported within the grooves 30 provided in the orifice 28 .

In such pipes, fluid is directed to port and starboard, and orifices create turbulence to promote mixing.

Next, the operation of the emulsifier of the present invention, which emulsifies and burns oil such as heavy oil to save oil, will be briefly explained.

The heavy oil, water, and emulsifier supplied from the heavy oil tank O1, the water tank W, and the emulsifier (bionics) tank V through their respective pipes at the desired mixing ratio as described above are supplied to the first emulsifying device 5 by the float switch 15. When the motor 10 is actuated by a signal, the rotary blade 11 is driven by shear propulsion in various directions as described above, and is violently struck against the side wall of the inner cylinder 9 and the bottom wall of the casing 11, creating intense turbulence, which gradually emulsifies. At the same time, the emulsified fluid circulates through the fluid passage formed by the casing 8 and the inner cylinder 9 as shown by arrows 26 and 27, and is sheared by the blade 11 each time, increasing the degree of emulsification.

When the water particles become about 1 to 3 microns, the emulsified state is completely destroyed, and the original heavy oil and water components are no longer separated.

Therefore, here, the circulation is repeated so that it approaches this value by a certain amount to promote emulsification and maintain the emulsified state.

Open the double valve 13 that has been circulated for the required time to release the emulsified fluid (
(heavy oil) is sent to the second emulsification means 14.

In the second emulsifying means, the pump 22 applies strong force to the pipe 1.
9, where a more homogeneous emulsifying effect is imparted by obstacles such as fins, again as described above, and a portion thereof is supplied to the combustion system via valve 24 and pipe 23.

The heavy oil emulsified in two stages in this manner is completely emulsified and does not separate into heavy oil and water components as in the prior art even if it is preheated before combustion.

The excess fluid portion not sent to the combustion system is connected to pipes 20 and 1.
The emulsified state is promoted and maintained within the circuit consisting of 9 and waits.

As is clear from the above explanation, in the emulsifying device according to the present invention, since emulsification is performed by the first and second emulsifying means, emulsification is performed more completely and more homogeneously than in the conventional device.
Substantially no component separation occurs.

In addition, the emulsified heavy oil is always kept in a fluid state within the first and second emulsifying means, and the emulsified state is not only maintained but also promoted, and there is no process of deterioration of the emulsified state as in the past. As a result, heavy oil consumption has been significantly reduced.

For example, 70% by weight of heavy oil, 30% by weight of water, emulsifier (
When 0.2% by weight of bionics) is mixed, approximately 1
Experiments have confirmed that 8% of heavy oil can be saved.

Furthermore, it has been confirmed that within the above-mentioned mixing range, 15 to 17% of heavy oil can be saved on average, and it has become clear that this method has a great effect on energy saving at a time when oil prices are soaring.

Finally, we will show the results of measuring the amount of water evaporation in the boiler when the emulsified heavy oil was combusted in the case where 8% of the weight was produced and when the emulsified heavy oil was emulsified with 70% of the weight of B and 30% of water.

These results demonstrate the above-mentioned effects.

In the actual measurement of combustion efficiency shown in the table below, evaporation multiple = water supply amount / oil supply amount. As mentioned above, when heavy oil is diluted and emulsified with water, heavy oil consumption can be saved compared to when heavy oil is used alone. It is as follows.
