Outlet discharge.
2) in the case of recovery section waste heat, adjusted by the temperature feedback of temperature-detecting device to control to adjust No.1 outlet
The aperture of valve, opens No.1 air flow rate adjustment valve, closes No. two air flow rate adjustment valves, opens No. two outlet regulating valves.It is empty
Gas is divided into two parts after air inlet adjustment valve enters flue gas heat-exchange unit heating after air-introduced machine pressurizes, and a part is gone out by No.1
Gas port is discharged, and another part is arranged after No.1 air flow rate adjustment valve enters air-water heat exchanger cooling by No. two gas outlets
Go out.The air-water heat exchanger heat absorbing side comes from heat supply network backwater or other, and heat supply network water supply or other is gone to after hot air.
3) heat need it is larger in the case of, particularly in warm season freeze-up, it is necessary to which recovery waste heat to greatest extent, is closed
No.1 outlet regulating valve and No. two outlet regulating valves are closed, opens No.1 air flow rate adjustment valve and No. two air flow rate adjustment valves,
Air inlet adjustment valve opening is adjusted to act on as level pressure.Air follows in the closed loop air flue between flue gas heat-exchange unit and air-water heat exchanger
Ring, achievees the purpose that at utmost Mist heat recovering.
Compared with prior art, the beneficial effects of the utility model are：
1) flue gas waste heat recovery apparatus of the utility model is added and does not influence copper work relieving haperacidity and normally produce；
2) flue gas waste heat recovery of the utility model can be used for Winter heat supply or the hot water of specified parameter is used for other use
On the way, such as summer across season soil heat accumulation, and then energy consumption is saved, improves the disposable efficiency of energy utilization in copper work.
