Description

Fuel oil emulsifier at random

The utility model relates to and a kind of two or more liquid is carried out mixing and emulsifying, particularly water and fuel oil is carried out emulsification and and the fuel oil emulsifier that is fitted together of burner.

Adopt the not only fuel-economizing of ginseng water emulsified fuel, and can reduce flue dust and harmful substance.Preparation emulsified fuel key is an emulsifying device.High-speed stirred emulsifying device at present commonly used, mechanism is huge, rotating speed is high, noise is big, and discontinuous operation, once tens kilograms of fuel oils of emulsification only.Because the restriction of this mechanism, operating procedure all must be finished at the emulsification station, then emulsified fuel is transported to the user.Obviously, build emulsification station, huge warehousing and transportation facilities, facility such as fire-proof and explosion-proof must increase cost, and the requirement of the stability of emulsified fuel has been increased technical difficulty, also influenced the popularization of technology.

The purpose of this utility model is the fuel oil emulsifier that a kind of easy to use, dependable performance will be provided.

In order to reach the technical scheme that the purpose of this utility model takes is a kind of fuel oil emulsifier at random, it comprises nozzle 1, the miniature emulsifier 2 that matches with the arrival end of nozzle 1, the oil pump 4 that is contained in miniature emulsifier 2 other ends, the blender 5 that links to each other with the arrival end of oil pump 4, and the other end of blender 5 communicates with fuel tank 9 and water tank 8;

Above-mentioned miniature emulsifier 2 comprises shell 11, the multistage double helix emulsification still 10 that axially links to each other, and each grade double helix emulsification still 10 reaches two helical blades 12 that are located at relatively symmetrically on the axle 13 by axle 13 and constitutes; The helical blade 12 of adjacent two-stage certain angle that staggers mutually, and hand of helix is opposite;

The head and end of multistage continuous axle 13 is taper;

The helical blade 12 of adjacent two-stage stagger mutually 90 the degree.

Because the utility model is to follow burner together, the burning of emulsification limit, limit, there is not requirement to emulsified fuel stability, thereby solved emulsification station emulsified fuel because of not being to use the difficult problem that water-oil separating takes place immediately, and the investment of having saved the emulsification station, reliable operation, the danger of the blast of not catching fire; Power consumption only accounts for 1/5th of stirring and emulsifying.Simple in structure, serviceability is reliable, low cost and other advantages so the utlity model has.

Fig. 4 is the expansion schematic diagram of double helix emulsification still in the miniature emulsifier of the present utility model.

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1,1 is nozzle, and it can be the nozzle on engine, the burner etc., and 2 is the miniature emulsifier that cooperates with the arrival end of nozzle 1, and 3 and 6 is flowmeter, and 4 is oil pump, and 5 is blender, and 7 is electric control valve, and 8 is water tank, and 9 is fuel tank.Nozzle 1, miniature emulsifier 2, oil pump 4, blender 5, flowmeter 3 and fuel tank 9 are formed working connection, and the water route is made up of flowmeter 6, electric control valve 7 and water tank 8.Fuel oil emulsifier at random shown in the figure is to install a miniature emulsifier 2 additional in the porch of the nozzle 1 of fuel oil equipment, and oil-water mixture is carried out emulsification, inserts a flowmeter 3 before the inlet of miniature emulsifier 2 and between the oil pump 4, to measure total flow; Before oil pump 4 inlets, blender 5 is housed, does profit and mix for the first time; The inlet of blender leads to fuel tank 9; In the water route, insert a flowmeter 6 between electric control valve 7 and blender 5, to measure the flow of water, electric control valve 7 is used to control the flow of water, supplies water in proportion or the cut-out water route.

As shown in Figure 2,10 is spiral emulsification still, and 11 is shell; Spiral emulsification still 10 and shell 11 are formed miniature emulsifier.

As shown in Figure 3,13 is axle, and 12 for being located at the helical blade on the axle 13 relatively symmetrically.Axle 13 and helical blade 12 constitute spiral emulsification still 10.

When fuel oil adds water mixed liquid and enters the inlet of miniature emulsifier, the awl end of the axle of spiral emulsification still circularizes the liquid conductance, enter in the helix groove of first order spiral emulsification still, mixed liquor rises along bifilar helix groove high-speed screw, and rise and constantly change direction along axial rotation, to first order helical blade end outlet, liquid stream is to clash into to second level helical blade head end at a high speed, and rise along second level helix groove high-speed screw, repeat said process, through multilevel action, mixing material forms emulsified fuel, is discharged by final stage; Liquid stream is rotating in the ascending motion at a high speed, constantly change direction and high-speed impact, produce violent eddy current at cross-sectional direction, these eddy current have very strong shear action to liquid, and---displacement---converges by cutting apart repeatedly to make liquid, form tiny particulate, water particle is distributed in the fuel oil equably, forms emulsified fuel, and its particulate is minimum, little of several microns, created condition for the subsequent processing spray burning.

When oil pump is worked, electric control valve 7 is opened, profit is inhaled into pipeline simultaneously in proportion from fuel tank 9 and water tank 8, oil directly enters blender 5, water enters blender 5 by flowmeter 6 and just mixes with oil, just the profit that mixes is sent to flowmeter 3 after entering the oil pump pressurization, enters miniature emulsifier 2 then and carries out emulsification, forms emulsified fuel and enters the nozzle atomization burning.

The utility model can be used for combustion apparatus, as the fuel emulsification of oil burner, boiler, heating furnace, hot-blast stove, kiln and internal combustion engine etc.The miniature emulsifier of core component in the utility model also can be used for the emulsification of oil, chemical industry, cosmetics, medicine etc.
