Below in conjunction with accompanying drawing the present invention is further described.
Shown in Figure 1 is emulsion manufacturing process flow diagram of the present invention.
Shown in Figure 2 is emulsifying mixer master sectional view of the present invention.
Fig. 3 is A-A among Fig. 2, C-C sectional view.
Fig. 4 is B-B among Fig. 2, D-D sectional view.
Among the figure, 1-heavy oil inlet, the outlet of 2-oil in water emulsion, 3-water inlet, 4-emulsifying mixer urceolus, 5-emulsifying mixer inner core, 6-spray orifice, 7-emulsion tube center, the 9-heavy oil service tank, 10-strainer, 11-pump, 12-pressure-regulator, the 13-heavy oil heater, 14-thermoswitch, 15-flow control valve, 16-magnetic valve, the 17-fuel nozzle, 18-water basin, 23-emulsifying mixer, the 24-plunger type metering pump, 25-water heater, 26-normally closed type pressure solenoid valve.
Referring to Fig. 1, in emulsifying process of the present invention, heavy oil pumps after heavy oil service tank (9) is sucked by pump (11) through filter (10), by steam heat-exchanging type heavy oil heater (13), the heavy oil inlet (1) from emulsifying mixer of the present invention (23) enters this emulsifying mixer inner core (5) again; Water calculates pump (24) suction through filter (10) by plunger tpe from water basin (18) and pumps, after electrothermic type water heater (25) heating, go to the emulsifying mixer (23) that is arranged between heavy oil heater (13) and the fuel nozzle (17), water-in (3) by this emulsifying mixer enters, spray orifice (6) on inner tube wall (5) is injected in the heavy oil in the inner core, water is ground into the granule subgroup of 1.5-10 μ, and heavy oil just becomes water-in-oil type emulsified fuel and is sent to fuel nozzle (17) and burns.
Emulsifying mixer of the present invention is when work, and the hydraulic pressure that enters in the emulsifying mixer urceolus (4) must satisfy following equation:
(P)/(γ) = (Po)/(γo) + (W
2)/(2g) + ξ (W
2)/(2g)
In the formula, the pressure of water in the P-urceolus (4), heavy oil pressure in the Po-inner core (5), the severe of γ-water, the severe of γ o-heavy oil, the speed that W-water sprays from spray orifice (6), g-universal gravity constant, the resistance coefficient in ξ-spray orifice (6).
That is to say, in emulsion process, require the pressure of water in the emulsifying mixer urceolus (4) can will correspondingly compensate the pressure energy of heavy oil in the inner core (5), speed energy that water converts to and the drag losses in the spray orifice at any time in spray orifice.Because in this emulsifying process system, adopted plunger type metering pump (24), so when watering quantity was turned down, the needed pressure of emulsifying mixer emulsification can be also little, the automatic reduction of outlet pressure of plunger type metering pump (24) at this moment adapts with it; Transfer when big when watering quantity, the needed pressure of emulsifying mixer emulsification can be also big, and the outlet pressure of plunger type metering pump raises and adapts with it.If the pressure in the emulsifying mixer inner core (5) raises, the outlet pressure of plunger metering pump (24) also raises automatically and adapts with it.Therefore, this emulsifying process system at any time can both satisfy the emulsifying mixer requirements of one's work well, makes emulsion quality high and stablize.Simultaneously, because plunger type metering pump carries flow control device, therefore, watering quantity does not need extra metering, setting device, and this has just simplified system greatly.
