1. anti-fouling countercurrent calandria heat exchanger, comprise:

  • heating installation import (1), heating outlet (10), running water inlet (9), running water outlet (2), it is characterized in that;

    also comprise;

    the longitudinal section more than three or three is the running water endothermic tube (3) of rectangle, arrange side by side between the running water endothermic tube (3), correspondence has an opening (8) on the tube wall of a common end of two adjacent running water endothermic tubes (3), and correspondence has another opening (8) on the tube wall of another common ends of next adjacent two running water endothermic tubes (3);

    Be communicated with by opening (8) between the running water endothermic tube (3);

    The two ends of running water endothermic tube (3) are connected with shutoff plate (7);

    Be provided with heating tube (4) in the running water endothermic tube (3), be communicated with by heating tube communicating pipe (5) between heating tube (4) head and the tail, pass the opening (8) between the running water endothermic tube (3) heating tube communicating pipe (5);

    Heating installation import (1) and heating outlet (10) fixedly are communicated with the top and the end of heating tube (4) respectively, and running water inlet (9) and running water outlet (2) fixedly are communicated with the top and the end of running water endothermic tube (3) respectively;

    The heating hot water directed flow passage of forming by heating installation import (1), heating tube (4), heating tube communicating pipe (5), heating outlet (10), the running water directed flow channel direction of forming with running water inlet (9), running water endothermic tube (3), opening (8), running water outlet (2) is opposite, constitutes the counter-flow heat exchange structure.
