Background technology
PTFE (polytetrafluoroethylene (PTFE)) tubing has excellent high-low temperature resistant characteristic, can be grown under conditions of -190~260 DEG C
Phase uses.PTFE material has good chemical stability, and only performance can change under fluorine steam, alkali metal under high temperature, right
Other all dense, dilute inorganic Organic Acid and Bases, ester do not react.Low surface friction coefficient, water repellent is refused inside and outside dirt, tube wall
Not incrustation.It is nontoxic, the features such as nonflammable, with the high grade of transparency, it is widely used in fluoroplastics heat exchanger, heat steam pipe arrangement etc.
Field, tool has been widely used.
Therefore the heat exchanger run under the stronger environment of corrosivity, its inside is general to be all made of PTFE heat exchanger tubes, and
Due to containing substantial amounts of dust, PTFE heat exchanger tubes long-term worked in dust flue gas operation, its table in the flue gas under the environment again
Lamination ash is formd on face, is cleaned up if the dust stratification in PTFE heat exchange pipe surfaces is handled not in time, heat exchanger can be influenceed
Overall heat transfer effect.
Now the most frequently used cleaning method is rinsed by the PTFE heat exchanger tubes in operating personnel's water holding pipe heat exchanging device,
But, because heat exchanger is integrally huger, and the arrangement more intensive complexity, therefore adopt again of its internal PTFE heat exchanger tube
Operation of ascending a height not only is needed with this method operating personnel, insecurity is there is, and to being arranged on heat exchanger center
PTFE heat exchanger tubes do not flush position yet, and so the personal safety guarantee not only to operating personnel proposes high request, and PTFE is changed
Tube surface is also cleaned not thoroughly, while also result in the waste of water resource, increases the management cost of enterprise.
