In this utility model one helical fin heat exchange device technology scheme, further preferred technical scheme feature is:
Described helical fin heat exchanger tube is evenly distributed in the side of described inlet water tank and water tank.
Compared with prior art, this utility model has the following technical effect that:
Owing to the speed of boiler smoke out can reach 12-15m/s from Boiler flue pipe road, there is the biggest kinetic energy, arrive
By arranging power heat exchange pipeline section, boiler smoke dynamic impact problem heat exchange pipeline section drives helical fin heat exchanger tube to rotate, the most permissible
Reduce the kinetic energy of boiler smoke, reduce the speed of boiler smoke, increase helical fin heat exchanger tube simultaneously and rotate in the unit interval
The number of turns, makes helical fin and boiler smoke be fully contacted heat exchange, increases the heat exchange area of boiler smoke and helical fin, and raising is changed
The thermal efficiency；Again due to rotate helical fin heat exchanger tube can drive boiler smoke axially movable, the flue gas of axially-movable with
The flue gas of radial motion mutually converges, and forms flue gas turbulent flow, relatively increases heat exchange area, thus improves heat exchange effect further
Rate；
This utility model by helical fin heat exchanger tube being evenly distributed in the side of described inlet water tank and water tank,
