Abstract

PURPOSE: To prepare an oil-water suspension without using a chemical agent and without need for a moving member by allowing the outlet side of a helical cut of each helical disk to coincide with the inlet side of the helical cut of the subsequent helical disk through a spacer member with an abrupt transition point in between. CONSTITUTION: A suspending stack is formed by including eight independently reciprocating helical disks 25 and 26, i.e., the clockwise helical disks 26 and the counterclockwise helical disks 25, in the cylinder 17 body of the stack along with a spacer member 16. A deflector through an angle of 90 deg. is provided when an oil-water mixture flows from the disks 25 and 26 to the subsequent disks through the spacer member 16. The formation of an appropriate turbulent flow is ensured in the stack. The oil-water mixture strikes against each deflector through an angle of 90 deg. sufficient to cause slurrying.

FIELD OF THE INVENTION The present invention relates to the suspension of water / oil which is related to combustion efficiency, in particular without the use of chemicals,
It relates to a mechanical fluid suspension device having no moving parts at all.

[0002]

Water / oil suspensions improve combustion. When the heated water spreads in the fluid, the oil droplets undergo micro-destruction (micro-explosion) and are atomized. The atomized oil droplets will have a large surface area to produce the evaporation required for combustion. water/
Suspending oils usually requires chemical additives and operative agitators.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a simple geometrical mechanical suspension system for oil / water without the use of chemical additives and without complicated agitators. It is to be.

[0004]

SUMMARY OF THE INVENTION The present invention provides a mechanical suspension system for producing oil / water suspensions without the use of chemical agents. The oil is pumped axially at a reference pressure toward a suspended stack constructed by stacking alternating directed reciprocating spiral discs with isolation discs. Oil and water are introduced at the inlet end into a suspending stack constituted by a reciprocating set of spiral disks. For heavy oil, water is introduced laterally at a pressure higher than the oil pressure, shearing the oil flow. The water stream enters the oil stream to form a mixed stream. This mixed stream is passed through the suspension disk stack along a reciprocating spiral flow path. Each disk is formed by cutting the spiral flow path along the clockwise or counterclockwise direction. These reciprocating spiral discs are alternately oriented clockwise and counterclockwise, with a separating disc between them. A sharp right angle reversal transition point is formed in the isolation disc between the spiral discs. This mixed oil and water flow, which is only partially suspended by the water flow splitting into the oil flow, is the combined flow of the spiral flow path in the first isolation disk. It hits the right-angled part formed by the first spiral disk until it hits the transition point which is reversed. This reciprocating flow is initially guided in the clockwise direction, then strikes the flat surface of the isolating disk and turns at a right angle, then flows into the next spiral disk under violent turbulence and follows the counterclockwise flow path. Shed. The oil and water mixture becomes more and more suspended as the liquid stream undergoes a multi-stage reciprocating action through the stack. At the stack outlet, the oil / water suspension is rapidly sprayed into the interior of the combustion chamber before the oil and water eventually undergo stratification or separation. It has been experienced to save fuel, improve heat transfer, reduce soot, and reduce emissions to pollutants.

A feature of the present invention is a suspending disk having a linearly arranged set of alternating reciprocating spiral disks. Each pair of discs forms a reciprocal spiral flow path such that the clockwise spiral intersects the counterclockwise spiral at a right angle, and the counterclockwise spiral intersects at a right angle with the clockwise spiral. To do. This creates a complicated reciprocating spiral flow path for the oil flow, and a higher pressure water flow enters the oil flow, and the combined oil / water suspension is created. Turbulent flow is formed. This suspended turbulent oil / water flow is directed directly to the burner nozzle where it is discharged as a jet of suspended oil / water to produce a high pressure or air stream for combustion. Is atomized by.

Other objects, features and advantages of the present invention will be apparent from the following description, the accompanying drawings and the appended claims.

[0007]

DETAILED DESCRIPTION FIG. 1 shows a number of nozzle systems. The oil inlet pipe 1 supplies fuel oil (at an intermediate pressure) to the suspending stack 2. A water inlet gate valve 3 introduces water under high pressure through a water line 4 into each of the suspension stacks 2. The water pressure needs to be higher than the oil pressure in order to force the oil flow and the water flow into the suspension stack 2. For light oils such as number 2 fuel oil (diesel oil), the water differential pressure is minimized.

Water is supplied to the water line 4 from a water pump 5 which is a constant pressure pump. A water pump 5 delivers water to each suspension chamber or stack 2 through a shutoff valve 6 and a check valve 7 and a gate valve 3. The suspension chamber or stack 2 delivers a suspended stream of oil / water to the jet nozzle 8 through a flexible outlet pipe 9. The pump 5 obtains the supply water from the water source 11 through the water supply pipe 10. For use with light oil, relatively simple float controlled constant head water can be used in place of the constant pressure pump.

FIG. 2 shows a cross section of a mechanical suspension stack (denoted by 2 in FIG. 1). Water delivered to the suspending stack flows through the needle valve assemblies 12-14. The needle valve assembly can be water regulated to range from 0 to 15% water to oil, either manually or by some well-known automation technique. The adjustment handle 12 allows adjustment of the needle 13, which is sealed by an O-ring packing 14 to prevent leakage. The O-ring stack includes a cylindrical housing 15. A separating member 16, which is a disc with a cutout, guides the oil / water mixture axially through the cylindrical housing 15. The cylinder 17 is screwed into the opening of a concentric connector / adapter 18. The adapter 18 seals the openings of the suspension stack, and the alternating spiral discs 2 acting in a reciprocating manner.
5 to 26 and serve to hold together the isolation member 16 interposed therebetween. The tube 19 directs water into the suspending stack at pressures slightly above the oil pressure to very high pressures due to the viscosity of the oil. The tube connectors 20-23 achieve the water supply to the suspension stack. The suspension stack comprises, in the illustrated embodiment, eight individual reciprocating spiral discs 25-2.
6, a clockwise disc 26 and a counterclockwise disc 25, together with the isolation member 16, are included within the body of the cylinder 17 of the suspension stack. A 90 ° turn is provided as the oil / water flows from each reciprocating spiral disk 25 or 26 through the isolator 16 to the next reciprocating spiral disk.

This structure ensures that a suitably turbulent water stream is formed inside the suspension stack. The oil / water mixture encounters each 90 ° turn of sufficient severity to cause suspension. This turbulence produces shear forces due to differences in viscosity, velocity, density and surface tension between oil and water. This causes mechanical suspension without the need for stirrers or chemicals.

The oil supply is provided by a conventional pipe 24, and if necessary by conventional equipment for metering.

Operation FIG. 1 illustrates how an oil / water suspension system may be used in multiple jet injection systems.

FIG. 2 selects the oil flow size by means not shown. Nozzle valve 13 for water supply
Is selected for each burner nozzle by setting. The water is under constant pressure, so that the oil supply and the water supply are matched to each other depending on the supply of the oil / water suspension to the burner nozzle concerned. The disks 25 and 26 are alternately arranged in the stack in a counterclockwise and clockwise direction, respectively, and their holes form a flow path having a high impact at an internal corner of 90 ° formed by interposing a separating member. like,
Be aligned. The two segments form a small and complex flow path where reversal occurs at the transition point of each disc. The oil / water mixture reaches the flat surface on the remote side of the spiral flow path through the first disk, rebounds from the flat surface, and the fluid continues to flow along the flow path to cause suspension. Resume what happens.

Although the present invention has heretofore been shown as a fuel suspension system, those skilled in the art will appreciate that, in addition to the changes described, other changes are noted in the claims section. It will be clear that this can be achieved without departing from the spirit and scope of.
