JPS58140507A - Device for emulsification of fuel oil - Google Patents

Abstract

PURPOSE:To carry out rapid and complete emulsification of fuel oil by turning the fuel while dispersing the same by imparting the centrifugal force within a vertical type cylinder, pulverizing the fuel by a cavitation effect due to blades and mixing water therein. CONSTITUTION:Oil supplied to a guide pipe C turns and descends due to centrifugal rotatioon, and hence the inner part of a mixer casing (b) assumes a negative pressure. Accordingly, water from a feed water pipe (d) is agitated while maintaining a wide contact face with oil. When a mixture solution of oil and water passes through blades 3, the emulsification of oil is completed by a super pulverization effect or the like of particles due to the cavitation effect, and the increase in the vibration of the liquid molecules by the ultrasonic wave vibration. Accordingly, rapid and complete emulsification of oil can be achieved.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an apparatus for mechanical emulsification of liquid fuels.

Mixing water with fuel to form a fine emulsion has been proposed as a way to reduce fuel costs and improve fuel efficiency for combustion equipment that uses petroleum as fuel.
There is no method that has specifically and completely achieved emulsification. Although emulsification is easy using an emulsifier, it hinders combustion, so this invention aims to quickly and completely achieve emulsion formation by mechanical means. Specifically, the centrifugal force is applied to the fuel inside the a-type chamber, causing the fuel to spin while being rotated, and the resulting swirling aS flow is passed through the blades of the airfoil to create a gear rotation effect, etc. During this process, the water sucked in by the negative pressure inside the cylinder is mixed.

To explain the embodiment of this invention device, this device consists of a chamber a that stores oil pumped by an oil pump.
, a guide pipe C communicating with the chamber itself and the lower mixer casing b, a water supply pipe d attached to the mixer casing b, and a separating blade N@ and a reverse blade 1 in the mixer casing b. configured.

The i-vibes C are a plurality of pipes that pass through the cap l of the mixer casing b and have their lower ends closely attached at an angle to the upper inner periphery of the casing. The water supply pipe is opened above the lower end of the guide pipe C or provided in the cap L (not shown). The mixer casing b has a vertical cylindrical shape and has a shaft 2 in its center. is supported by the postscript. On the shaft 2, three mixing blades 3 having a cross section similar to that of an aircraft wing are arranged in a violet pattern, and one set is arranged in four forks, and the front end of each mixing blade 3 is attached to a mixer casing b. The shaft 2 is supported by being fixed to. This shaft 2 and the three groups of mixing blades constitute a separating blade II. The reverse blade f has a plurality of planar fan-shaped plates 5 radially provided on a short shaft 4 at vertical intervals and projecting at an angle, and the plates 5 are fixed to the mixer casing b.

According to the above configuration, the oil pressure fed to the chamber 1 is adjusted in hydraulic pressure and flows into the mixer casing b while maintaining equal pressure and flow velocity in each guide pipe C. At this time, since the lower end of each guide pipe (the lower end of the pipe is attached at an angle to the chamber axis direction of the shaft casing b and inside *1iv-s), the oil flows down while rotating due to centrifugal force, and due to centrifugal rotation. The oil layer diffuses to form a thin layer and the inner IWI
I! In order to swivel along the mixer casing bPJfIs&t! The i11 becomes a controlled cavity and the inside becomes negative pressure. Therefore, the water from the water supply pipe d is sucked in and accelerated, creating a high-speed swirling flow.
When a high-speed swirling flow of a mixed liquid of zero-order oil and water, which is moving while maintaining its contact surface while also swirling and descending while being stirred, passes through the three groups of mixing blades at high speed, the shape of each blade causes the liquid to The desired emulsification of the oil is completed due to the shape a@, the carrier and chision effect on the flow, the ultra-fine particle refinement effect due to the decrease in film resistance due to the increase in vibration of fluid molecules due to ultrasonic vibration, etc. Furthermore, the reverse blade 1 is used to make a sudden reverse rotation to complete the complete stirring operation. In this way, the present invention has the effect of achieving the iR purpose stated in the heading.

The device of the present invention that achieves the above-mentioned effects can be put into practical use by simply modifying the middle of the combustion equipment combustion system. The example is 1

The oil is sent to this invention device via a preheater 6 and a pump 7, where it is emulsified and sent to a service tank 8.
It accumulates in Eventually, as the oil storage level rises, the liquid level SW becomes active.
The valves Sv1 and SV2 are w8s, and the magnetic valve sva opens, but since the pump 7 is working, the emulsion in the jar and tank 8 passes through this invented device and repeats regeneration, and the emulsion is consumed in the burner 9. When the emulsion liquid level in the service tank 8 drops, the electromagnetic valve SV3 is closed using the liquid level SW, and the mai valves SVl and SV2 are opened to generate a new emulsion again.
