摘要
研究的塑料螺旋齿管自动清洗和传热强化技术,吸取了钢丝螺旋具有自动清洗和传热强化双重功能,且流体阻力小的优点。采用塑料内管同时解决塑料螺旋的刚性问题和钢丝螺旋线对管壁的磨损问题,并且还显著地增大管内实际流速的问题。因此,可以用于0.30m/s以上的低流速传热设备的自动清洗防垢和传热强化。
The paper researches the self-cleaning and heat transfer enhancement technique using plastic inserting tubes with spiral flange. It also has the both factions of steel spiral and the flow resistance is low. It uses plastic inserted tubes to make spiral rigid enough, avoids wear and tear on heat transfer pipes and increase the real flow velocity in pipes. So, the new technique can be used for heat exchangers of low flow velocity to remove or prevent fouling and enhance heat transfer.
