Description

Multistage heavy oil emulsive device

The utility model relates to a kind of water-blended heavy oil emulsified unit, belongs to the fuel energy-saving technical field.

Heavy oil is widely used as heating the boiler of stove, power large-scale electric generating station, the fuel of large ship engine in industrial production.Along with the continuous development of PETROLEUM PROCESSING to the degree of depth, the most viscosity of Gong Ying heavy oil is very high in the market, adopts common mechanical method atomizing effect bad.For addressing this problem, the methods that adopt the heavy oil emulsive burning promptly, are mixed a certain proportion of water in the heavy oil more in the industrial production, by emulsifying device water are distributed in the heavy oil with tiny state, make water-in-oil emulsion heavy oil.Emulsification heavy oil is behind the fuel injection nozzle burner hearth, and the globule that is comprised in the oil droplet of primary atomization is heated the back prior to heavy oil arrival boiling point, becomes water vapour.When the water vapour volume sharply expanded, making the oil droplet explosion was many more tiny oil droplets, thereby has expanded the total surface area of oil droplet, plays the effect of secondary-atomizing, and the efficiency of combustion of heavy oil is improved, and plays the purpose of fuel-economizing and pollution abatement.As, the resonant wedge whistle ultraemulsifier of Acoustical Inst., Chinese Academy of Sciences's development can be dispersed to the water droplet of 80%-95% below 5 microns; The full-automatic oil-water stirrer that Shengang Energy-saving Agent Co., Ltd. produces, watering quantity 10%-20% adds dosage 0.3%, disperses water droplet less than 5 microns account for more than 90%; The ZSR type heavy oil mixed with water mulser of the energy-conservation Research Institute of Shanghai second Industry Univ, watering quantity 5%-8%, rate of economizing gasoline 4%-8% disperses drop diameter 2-5 micron.Above-mentioned mulser mainly is made up of retort and rotation thumb wheel, adopts intermittently alr mode of single-stage, though play certain emulsification, emulsifying power is low, and emulsion quality is relatively poor.Simultaneously, above-mentioned heavy oil emulsive device structure is comparatively complicated, and operation and maintenance capacity are big.

The utility model purpose is to provide a kind of emulsifying power height, the measured multistage heavy oil emulsive device of matter, overcomes above-mentioned shortcoming of the prior art.

The purpose of this utility model is realized by following technical scheme:

A kind of multistage heavy oil emulsive device comprises shell, eddy flow section, recoil section in the composition, eddy flow section and recoil section are alternately arranged in the enclosure vertically.The structure of eddy flow section, recoil section is:

Eddy flow section: be formed in parallel by 2 above cyclone pipes, be provided with spinning disk in the cyclone pipe, fixedly connected between spinning disk and cyclone pipe inwall;

Recoil section: form by the recoil sheet that is fixed in more than 2 on the different sagittal planes, each sheet that recoils along Different Diameter to being staggered.

Above-mentioned multistage heavy oil emulsive device, described eddy flow section are 3-6, and 2 eddy flows are intersegmental to be provided with 1 recoil section, and described spinning disk is a helicoidal structure, and the rotation direction of spinning disk is opposite in the adjacent cyclone pipe.

Above-mentioned multistage heavy oil emulsive device, the recoil sheet in the described recoil section is a sector structure, and fan-shaped drift angle is 20 °-40 °, and the recoil sheet is fixed in outer casing inner wall more than 2, and each sheet that recoils equidistantly distributes vertically.

Above-mentioned multistage heavy oil emulsive device, described shell is a round tube shape structure, and each eddy flow section is provided with 2-8 cyclone pipe, and each recoil section is provided with 4 recoil sheets, and the spacing of adjacent two recoil sheets is 1/5 of the recoil segment length.

The utility model emulsifying power height, emulsion quality is good, because its inner movement-less part, thereby fault rate is extremely low, operation and easy to maintenance.Can improve the efficiency of combustion of heavy oil greatly, thereby realize the purpose of fuel-economizing and pollution abatement.Be particularly suited for the technological transformation of existing stove oil supply system, have great economic benefit and social benefit.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A generalized section of Fig. 1;

Fig. 3 is the B-B generalized section of Fig. 1;

Fig. 4 is the partial cutaway schematic of the utility model cyclone pipe.

As seen from Figure 1, the utility model is made up of shell 1, eddy flow section 2, recoil section 3, and eddy flow section 2 and recoil section 3 are alternately arranged in shell 1.Shell 1 is the round tube shape structure at two ends flanged 7, and according to the difference of producing required heavy oil flux, shell 1 diameter can be designed as 50-200mm.Eddy flow section 2 in the shell 1 is the series connection of 3-6 level, and 1 recoil section 3 is set between each eddy flow section 2.

Referring to Fig. 1, Fig. 2, Fig. 4, eddy flow section 2 is composed in parallel by 5 cyclone pipes 4, and it is that the steel pipe of 22-55mm is made tube wall that cyclone pipe 4 can be selected external diameter for use, and length is 80-200mm, in 3-8 helical form spinning disk 5 of welding, fixedly connected between helical form spinning disk 5 and cyclone pipe 4 inwalls.

Referring to Fig. 1, Fig. 3, recoil section 3 is made up of 4 fan-shaped recoil sheets 6 that are fixed on the different sagittal planes, recoil sheet 6 can adopt the thick steel plate of 3mm to make, its fan-shaped drift angle is 20 °-40 °, be fixed on shell 1 inwall, each sheet 6 that recoils equidistantly distributes vertically, and the spacing of adjacent two recoil sheets 6 is 1/5 of recoil section 3 length, and the axis projection of adjacent two recoil sheets 6 is 90 ° of angles.

When cyclone pipe 4 in eddy flow section 2 of the heavy oil with certain pressure and current, cut apart and mix by 5 rotations of helical form spinning disk rapidly.The rotation direction of adjacent cyclone pipe 4 inside spin shape spinning disks 5 is opposite in the eddy flow section 2, with the mixing effect of further reinforcement heavy oil and water.After heavy oil and water flowed out from one-level eddy flow section, the recoil section 3 of flowing through when the profit fluid-mixing carries out strong bump to the recoil sheet, had been strengthened the horizontal mixed effect of profit fluid-mixing.

Use the utility model emulsification heavy oil, can be with oil, water fluid-mixing eddy flow---recoil circulation repeatedly makes heavy oil recoil strongly with water two components and mixes, and makes moisture be more tiny droplet and is dispersed among the heavy oil, improves the emulsifying power and the quality of heavy oil greatly.After tested, drop diameter is less than 1 micron account for more than 90%, and rate of economizing gasoline can reach 8%-14%.
