10. efficient rotary pipe type heat transfer evaporator heat exchange method according to claim 1, which is characterized in that including walking as follows
It is rapid:
Firstly, the intracorporal pressure of cylinder is transferred to by the transpirable pressure of evaporated liquid by the escape pipe at the top of cylinder, it is small
Need cooled liquid on leading in diameter tube, minor diameter liquid in pipe temperature should be greater than being evaporated temperature and with evaporating pressure outside pipe
Matching；
Secondly, variable-frequency motor drives tubular shaft rotation, tubular shaft drives the Spiralism type dress on lower part rotation tubular device and top
It sets and rotate together at high speed, open the spout or spray head of liquid showering tube, the liquid that need to be evaporated pours the outer surface of minor diameter pipe, control
Liquid showering tube flow makes to form uniform liquid film on every minor diameter pipe；Because the temperature of liquid in pipe is greater than the steaming of the outer evaporation liquid of pipe
Temperature is sent out, liquid film is by rapid evaporation, in addition coil quickly rotates, forms certain wind speed, more accelerates the evaporation of liquid；Together
When, the minor diameter pipe due to liquid cooled in pipe Jing Guo many parallel connections, liquid resistance very little；
Thirdly, complete droplet is not evaporated to separate through the vane plate on top, it is suitable because centrifugal force effect is got rid of to cylinder inner wall
Inner wall to flow down, be then evaporated；
Thirdly, the liquid not being evaporated flows to container bottom, when bottoms level height is more than lower annular pipe, by loop pipe
Interior liquid warming is vigorously stirred by loop pipe again, is evaporated again quickly；
Finally, high-efficiency dehydration separating treatment of the gas of evaporation by top vane plate, the gas dripless of discharge, droplet hair
It is raw.
