Description

[Detailed Description of the Invention] The present invention relates to an apparatus for emulsifying heavy oil and the like and maintaining the emulsified state.

With the rise in oil prices, various methods have recently been developed and are attracting attention by adding water and emulsifiers to oil (heavy oil, etc.) for co-combustion.

The technology to emulsify oil such as heavy oil and water is currently '%
It cannot be said that it has been established.

This is because even if heavy oil, etc. is emulsified, if it is left unattended or stored in a storage tank, it will gradually separate into heavy oil and water components, and the heavy oil may end up being burned. Because there is.

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 parts farther away gradually separate into heavy oil components and water components. was there.

Accordingly, an object of the present invention is to provide a heavy oil emulsifier having a simple structure that can effectively and continuously emulsify heavy oil and maintain the emulsified state.

According to the present invention, an inner cylinder is disposed in a cylindrical casing with its upper and lower ends open, resulting in a double structure, and the lower part of the cylinder is arranged in a direction perpendicular to a direction parallel to the fluid flow direction. A rotating blade is provided to displace the fluid over a wide angular range, and the high-speed rotation of this rotating blade causes the fluid to move strongly toward the inner cylinder side surface and the bottom surface of the casing, thereby creating turbulent flow. At the same time as emulsifying, the emulsified state can be maintained and promoted by circulating through a fluid passage composed of a double structure of a casing and an inner cylinder.

It is preferable that the height of the inner cylinder within the casing is adjustable so that it can be adjusted depending on the quantity and quality of the fluid.

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.

As shown in Fig. 1, the heavy oil emulsifier 1 of the present invention has a double-cylinder structure in which an inner cylinder 3 is disposed inside a cylindrical casing 2, the upper end of which is open, and the lower part divided into eight chambers. A rotary blade driven by a motor 4 for emulsifying and propelling fluid is provided below the inner cylinder 3, and heavy oil, water, and emulsifier are supplied from the charging pipe 6 to the casing 2 as shown by an arrow 7. After being emulsified, it is discharged from a discharge pipe 8 to another system such as a combustion system as indicated by an arrow 9.

Preferably, the fluid level is detected by a float switch 10 to operate the motor 4.

An important word in this invention is that the inner cylinder 3 is inside the casing 2.
A fluid passage is provided by providing a fluid passage, and the fluid is sheared and propelled by the blade 5.

Therefore, it is preferable that the blade 5 be provided at a position below the inner cylinder 3, and that blade shapes such as those shown in FIG. 3 in an appropriate combination be used.

The blade of FIG. 3a has an upward end 11 which serves to propel the fluid laterally, i.e. at right angles to the direction of flow, towards the side of the inner cylinder.

The blade of FIG. 3b has a downwardly directed portion 12 at its distal end and thus has the effect of propelling the fluid downwards, ie towards the bottom of the casing 2.

The blade of Figure 3c has a twist 13 at its distal end, which serves to propel the fluid in a direction intermediate the angle of thrust of the blades of Figures 3a and 3c.

Next, the operation of the emulsifying device of the present invention will be briefly explained.

Via pipe 6, for example, 70-85% heavy oil, 15-85% heavy oil
When 30% by weight of water and about 0.2% by weight of emulsifier are charged into the casing 2, the predetermined level size float switch 1
0 activates motor 4.

The valve 14 is closed during startup and opened during normal operation.

The operation of the motor 4 causes the combined composite blades 5 to rotate, forcing the heavy oil, water, and emulsifier to be propelled in a parallel direction from a direction perpendicular to the side surface of the inner cylinder 3 toward the bottom of the casing 2 .

These fluids are subjected to intense shearing action from the rotating blades and are violently struck against the inner cylinder side surface and the bottom surface of the casing, creating turbulent flow, during which the particles of heavy oil, water, and emulsifier gradually become thinner and emulsified.

The thus emulsified fluid is forcibly circulated from the passage in the inner cylinder 3 through the passage between the inner cylinder and the casing as shown by arrows 15 and 16 by the propulsive force of the rotating blade, and each time the fluid is Since the emulsifying effect is applied nearby and the fluid is constantly circulated within the casing, once the fluid has been emulsified, the emulsified state is further promoted and maintained.

According to various experiments, it has been confirmed that the emulsified state is maintained when water particles are miniaturized to about 1 to 3 μm in size. By this constitution, the emulsified state progresses in a more stable direction and is maintained in that state.

This is because no part of the fluid is left to move with static gravity or slow velocity.

The fluid thus completely and stably emulsified is transferred via the tube 8 to other systems.

When the consumption of the casing or other systems is small, or when the viscosity is too high and complete emulsification is difficult, the height of the inner cylinder 3 within the casing 2 can be adjusted as shown in Figure 3. It is better to lower it so that the fluid undergoes emulsification in a shorter circulation cycle.

In such a case, it goes without saying that the angle, shape, size, or rotational speed of the blade surface may be changed depending on the oil or the like used.

For adjusting the height of the inner cylinder, it is practically convenient to configure the inner cylinder with a plurality of cylinders so that they can be slid telescopically.

In one configuration example of this equipment, the amount of heavy oil required per hour is approximately IA.
It has been confirmed that it is suitable to design the device so that the
Emulsification takes about 15 to 20 minutes at 000 rpm.

As is clear from the above explanation, the heavy oil emulsification apparatus according to the present invention has many advantages as follows.

0) It is possible to repeatedly achieve a more stable emulsified state and maintain the emulsified state using a device with a simple structure.

(2) The circulation emulsification cycle can be changed by moving the inner cylinder up and down depending on the consumption amount of emulsified heavy oil, the viscosity of the oil, etc.

(3) Even when temporarily stored, the emulsified state is not impaired.
