Abstract
The application discloses an energy-saving heat exchanger and belongs to the technical field of heat exchange equipment. The energy-saving heat exchanger comprises a shell, upper and lower end sleeves are respectively arranged at two ends of the shell, and a heat conduction pipe is arranged in the shell. A low-temperature fluid input port and a low-temperature fluid output port are arranged on the shell. Steam input ports and steam output ports are respectively arranged on the upper and lower end sleeves. A spiral propeller driven by fluid impact force drives a drain pipe to rotate, the drain pipe drives a scraper to rotate, the scraper pushes condensate water adhered to the inner wall of the heat conduction pipe, the condensate water on the inner wall of the heat conduction pipe is gathered together to form water drops with a larger volume, the water drops flow along the side wall of the scraper to the flow guide groove under the action of gravity of the water drops, the water drops flow to the drain pipe along the flow guide groove arranged in a slope, and then the water drops are discharged into a space below a partition plate in the lower end sleeve through the drain pipe. The energy-saving heat exchanger accelerates the transfer rate of the condensate water on the inner wall of the heat conduction pipe, increases the contact probability of steam and the heat conduction pipe, and improves the heat exchange effect.
