Iridium heavy oil multi-stage and four-stage combined colloid mill, grinding pump is a mechanical high-speed shear pulverization grinding principle, which will mix a certain proportion of heavy oil, water, emulsifier and other liquids into the working chamber. High-viscosity, heavy friction, strong friction, particle shredding and other complex and powerful mechanical movements and diversified high-frequency shear grinding to break the molecular chain of heavy oil droplets, break water particles, etc. The high-frequency friction, violent vibration and turbulent flow of the oil after the high-speed friction of the thousands of blades subjected to the uneven grinding process cause the droplets of the liquid droplets to break, thereby reducing the viscosity of the heavy oil and making the emulsifier more effective to exert hydrophilic action. The fine emulsifier and the fine water particles are uniformly distributed in the heavy oil to form a water-in-oil emulsion. Water-in-oil colloid mill|Quad colloid mill|Combined colloid mill|Heavy oil colloid mill will heavy oil colloid mill working chamber emulsified water-in-water catalyzed evenly sprayed into the furnace through the mist, once the oil droplets on the heavy oil surface Being burned, the tiny water droplets in the oil are heated and vaporized, and the volume is rapidly expanded to instantly explode the oil droplets (secondary atomization). In the secondary atomization, due to the micro-explosion effect generated by the oil droplets, the micro-oil blast is caused again. Disperse into a finer misty oil droplet at a time. At this time, the oil droplet has a large specific surface area and is fully combusted after contact with oxygen in the air, which effectively increases the flame brightness and shortens the burning time, so that the heavy oil is completely burned and the thermal effect is eliminated. The discharge of black smoke has reached the goal of saving fuel.
