  • Self-cleaning heat exchanger using system for supplying solid particle and water
    Patent number: 8181693
    Abstract: A self-cleaning, shell and tube type heat exchanger using a solid particle-water supply system. The heat exchanger includes solid particle supplying means for storing and supplying solid particles to be used in cleaning the heat exchanger tubes, and water supply means for fluidizing the solid particles stored in the solid particle supplying means so as to supply the solid particles into a mixed fluid discharging means, or for directly supplying water to the mixed fluid discharging means. The mixed fluid discharging means sucks the supplied solid particles and water, and sprays the supplied solid particles and water as a mixed fluid from above the vertical heat transfer tube arrangement such that inside surface of the heat transfer tubes can be cleaned. Separating means separates the mixed fluid used in cleaning the heat transfer tubes into solid particles and water, using a gravitational separation method.
