Boiler water disposal equipment
Boiler water disposal equipment
To as thermodynamic system actuating medium and cooling medium de
water have strict water quality request in thermal station's
vapor's circulatory system, be like high pressure boiler to
feedwater Water not only request hardness low, dissolve oxygen's
quantity pole slight, solid's content and organic matter's content
too pole slight, have no reach supply water normative water will
make power plant equipment can not safety economic execution, has
therefore already enacted thermal station all sorts of use watery
index of quality.
Power plant mend supply water always originated from surface water,
ground water, coastal area and be short of fresh water area give
back always think seawater for supply water source, water all had
to by sediment, percolation, doff salt, doff gas dispose behind
talent come into power plant de water circulation's system.
In membrane's disposal system, use make front dispose de exceed
sieve ordinary use diameter 1mm de medium-altitude fiber, as doff
except suspended solid and colloid raw water in, UF serve as front
dispose de biggest problem is membrane pollute and membrane hole
jam, therefore always in front set up in advance filter, as wipe
off big grain path suspended solid, filtrate front plus wadding
congeal dosage at in advance, be like PAC (forgather third be thin
sour) can enhance filtrate water quality, and debase membrane's
resistance. To power plant's boiler supply water system's request
de dissolve oxygen's quantity's ordinary request for 0.3 mg/ L
under, therefore doff gas' membrane should at under 5.33Kpa
(40TORR) de operation under vacuity.
