Production Principle of Bitumen Emulsion Plant

The emulsified bitumen just produced by the bitumen emulsification equipment should be cooled in time to avoid the evaporation of water vapor in time and to prevent early demulsification, which is conducive to storage and transportation. So, what is the production principle of bitumen emulsification equipment?

To cool the emulsified bitumen in time, a cooler needs to be installed at the outlet of the emulsification pump of the emulsified bitumen equipment. When the hot bitumen flows through the column tube, the cold water outside the tube cools it and the water itself is heated. The hot water flowing from the cooler is sent to the front hot water recovery tank through the pipeline. Emulsifier tank, latex tank, temporary soap storage tank, static mixer, pipeline transportation and filtration system, inlet and outlet valve control system, pipeline-type multi-stage emulsification pump as the main body of the machine, equipped with heating and insulation, metering detection, electrical control, etc. The system makes this if the process effect is high, the emulsified bitumen equipment operates reliably, and the overall layout of the equipment is reasonable, which can reduce emulsification costs, and effectively prevent the emulsified bitumen from breaking, which is economical. Not only has it created profits for companies, it has also provided convenience for consumers.

bitumen emulsification equipment In the bitumen-water system, the emulsifier molecules move between the bitumen and the water interface. The water-reducing groups of the molecules are adsorbed on the surface of the bitumen and make them charged, while the hydrophilic groups enter the water. phase. As a result, the bitumen particles are connected with water, which reduces the interfacial tension between the two. At the same time, the bitumen particles have the same charge and repel each other, preventing them from coagulating with each other, so that the bitumen emulsion can be kept uniform and stable for a certain period of time. The nature of the charge depends on the charge of the hydrophobic group or the hydrocarbon chain portion of the emulsifier. If it is negatively charged, the bitumen particles are negatively charged and the emulsion formed is an anionic bitumen emulsion. On the contrary, it is cationic bitumen emulsion. If the bitumen particles have both negative and positive charges, the emulsion is a zwitterionic bitumen emulsion; in addition, there is a non-ionic bitumen liquid. Pay attention to the bitumen emulsification equipment during transportation and storage.
