Using method explanation:
In actual use, for the new heating system used, then use pattern one, i.e. to heating system filling circulation
The supermolecule nursing agent of the first metering is filled, in heating system normal course of operation, at interval of the time of setting, again while water
The supermolecule nursing agent of filling the second metering is supplemented in heating system；Wherein, the adding amount of recirculated water is L, and supermolecule is nursed
The adding amount of the first metering of agent is 0.01 ~ 0.02L, and the adding amount of the second metering of supermolecule nursing agent is 0.003 ~ 0.007
L。
In actual use, in the heating system run, because there being the situation of fouling inside it,
Then use pattern two, i.e. to the supermolecule nursing agent of heating system filling the 3rd metering, after heating system runs the setting time, as
Really recirculated water becomes translucent dark brown liquid, then maintain heating system to continue to run with, if recirculated water is still dirty solution
Body, the most again to the supermolecule nursing agent of heating system filling the 4th metering, after heating system runs the setting time, by heat supply system
Recirculated water emptying in system, the mode according still further to pattern one operates；Wherein, the filling of the 3rd metering of supermolecule nursing agent
Amount is 0.03 ~ 0.04L, and the adding amount of the 4th metering of supermolecule nursing agent is 0.04 ~ 0.06 L.
Illustrating, the heating system accepting certain community processes engineering.This District Heating System is possessed the water yield and is about 400m
, heating system is because having used, and there is slight corrosion and scaling phenomenon inside.According to possessing the water yield 3% adds circulation water for heating
Supermolecule nursing agent, dosage is 12m, and within 4 days, Posterior circle water is translucent dark brown, is not required to change water dosing, allows medicament with following
Ring water continues to run with.Medicament forms one layer of form compact and stable Supermolecular film in metal surface according to supramolecular self assembly effect,
Assembling during film forming, can be by the rusty stain of metal surface, incrustation scale, calcium dirt etc. is broken to be dissipated, dissolve, simultaneously because Supermolecular film
According to dirty effect, can effectively stop dirt adhere to, protect metal not to be corroded, be not required to individually carry out blowdown, make circulation water for heating
Reach almost zero burn into zero fouling, zero blowdown.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although
With reference to previous embodiment, the present invention is described in detail, it will be understood by those within the art that: it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent；
And these amendment or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
