While doing its own environmental protection work, an environmental protection device and latent heat recovery device were added to the production equipment. Recovering heat back, reducing energy consumption, how to make the bitumen emulsion plant energy-saving?

Emulsified bitumen is used as a finished product in the production process. The outlet temperature of ordinary emulsified bitumen is mostly around 85 ° C, and the outlet temperature of emulsified modified bitumen is above 95 ° C. Latent heat in emulsified asphalt Many emulsified asphalt equipment is not used, but directly into the finished product tank, the heat is arbitrarily lost, resulting in waste of energy.

During the production of bitumen emulsion plant, water as a raw material needs to be heated from normal temperature to about 55 ° C. We have designed a heat exchanger to heat the latent heat of the emulsified bitumen to water. It was found that after the production of emulsified bitumen 5 tons, with the gradual increase of the temperature of the circulating water, the circulating water was used for the production water, and the water was basically not heated, and only 1/2 of the fuel was saved from the energy side.
