Matter is absorbed heat, and temperature raises, and is partly into air preheater 8, is partly into boiler 1 water tank；
After the heat transferring medium of air inlet preheater 8 and Cryogenic air carry out heat exchange, air absorbs heat, and temperature raises, complete
Become the heat of boiler 1 air intake；
After the heat transferring medium of entrance boiler 1 water tank carries out heat exchange with softened water, softened water absorbs heat, and temperature raises, and passes through
The softening water out of boiler 1 water tank enters boiler 1 and softens water inlet, that is, achieve the heating to boiler 1 softened water, heat transferring medium
Return to vertical lower resistance cooling system 3 again through circulating pump after heat release and carry out the heat exchange heating up of absorbing heat.
In the process, boiler 1 flue gas is down to 80 DEG C about from 160 DEG C about, steam coagulation therein, soxAnd nox
The overwhelming majority is condensed into acid dew, takes full advantage of the vapour of vapor in boiler 1 flue gas using this vertical lower resistance cooling system 3
Change latent heat, high efficiente callback heat；Using the thermal cycle pipeline of the present invention realize reclaiming heat to the preheating of boiler 1 cold air and
Preheating to softened water needed for boiler 1, is truly realized the closed loop application of heat energy, improves energy utilization rate.
Except be used softened water as liquid heat transfer medium in addition to, can also according to working condition different using other liquid
(as conduction oil, freon etc.), as heat transferring medium, is suitable for the heat transfer requirements of different temperatures.
When being used softened water as heat transferring medium, the heat exchanger in boiler 1 water tank can be cancelled, and so that feed liquor arm is gone out
Mouth gos deep into below the liquid level of water tank, makes hot mastication water and low temperature softening water directly contact carry out heat exchange, improves heat exchange efficiency.
The softened water of intensification of now absorbing heat in vertical lower resistance cooling system 3 is directly entered boiler 1 water by inlet
Case, the softened water relatively low with wherein temperature directly mixes, and then a part returns to circulation line by liquid outlet, and another part leads to
Cross softening water out and enter boiler 1 softening water inlet, supply boiler 1 uses.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, some deformation can also be made and improve, these broadly fall into the protection model of the present invention
Enclose.
