Two class of surface and ground water can be divided into according to the source of water.Surface water typically contains 2-3 ㎏/ton water minerals, and underground water
Generally contain 20-50 ㎏/ton water minerals.These minerals can constantly be crystallized out from water in circulation or movement,
And it is attached to the inner surface of pipeline or heat exchanger.We term it " dirts ".Since the thermal coefficient of dirt is minimum, only metal
1-5% can greatly affect the conduction of heat, reduce the efficiency of heat transfer.In many occasions serious influence production and
Life.
Currently, the domestic technology in industrial antiscale, scale removal is also concentrated mainly on the following aspects:
Chemical method --- by the way that a certain amount of antisludging agent is added in the solution, change a series of physical chemical characteristic of water,
To play certain scale effect.Its shortcomings that is higher cost, easily causes secondary pollution, is had centainly to pipeline, heat exchanger
Corrosion and scale removal effect it is limited.
Physical method --- the mode relatively approved at present has the modes such as ultrasonic wave, magnetization, resonance.They are " flat in fluid
When stream " state, there is certain effect in terms of scale inhibition, antiscale.But the heat-exchange fluid industrially used is largely in " turbulent flow "
State.When using these methods, external energy is required, there is certain limitation in use occasions such as field, high-altitude, high temperature.
Physics+chemical method --- when having already appeared situation of the scale effect to heat transfer, typically using pickling+
The mode heat exchanging device of high pressure washing is safeguarded.But a large amount of product and raffinate by processing all without just discharging after pickling
, public environment is destroyed very big, it is also difficult to supervise.Meanwhile operator's is completely dependent on to the assurance of pickling intensity and time
Experience, it is easy to while scale removal, also damage pipe network and heat exchanger body.
