In：Including recycling as follows：
Hot net water cycle is as follows：Heat supply network bypass pipe is accessed on heat supply network return pipe, the heat supply network bypass installed in heat supply network bypass pipe is followed
Ring pump provides circulation power for required hot net water；
The hot net water cycle of bypass is as follows：The hot water of heat supply network bypass pipe respectively enters absorption heat pump and electric heating pump, absorbs heat
Heat supply network return pipe is returned afterwards, and which part hot net water enters smoke re-heater by flue gas reheat feed pipe and heats flue gas, reduces
The relative humidity of smoke evacuation eliminates " white cigarette " phenomenon, heats the hot net water after flue gas and returns to hot net water by flue gas reheat return pipe
Circulating line, smoke re-heater selective operation；
Remaining hot water cycle is as follows：Remaining hot water cycle is divided into absorption heat pump remaining hot water cyclic part and electric heating pump waste heat circulating part
Point；
Absorption heat pump remaining hot water water outlet passes through absorption heat pump remaining hot water feed pipe and absorption heat pump remaining hot water water distributor
Connection, the absorption heat pump remaining hot water that temperature is 25-30 DEG C are evenly distributed to absorption heat pump remaining hot water by water distributor and exchange heat
On filler, after remaining hot water and flue gas heat exchange, flue-gas temperature reduces, and deviates from the part vapor in flue gas, while waste heat water temperature
Degree raising, fume afterheat are transferred in remaining hot water, and the remaining hot water after heating enters suction by absorption heat pump return afterheat-water pipe
Receipts formula heat pump, the absorption heat pump waste heat water-circulating pump installed on absorption heat pump return afterheat-water pipe are provided for remaining hot water cycle
Circulation power；
Electric heating pump remaining hot water water outlet is connect by electric heating pump remaining hot water feed pipe with electric heating pump remaining hot water water distributor, temperature 0-
5 DEG C of electric heating pump remaining hot water is evenly distributed to by electric heating pump waste heat water distributor on electric heating pump remaining hot water heat exchange filler, with cigarette
Gas exchanges heat, and further reduces flue-gas temperature to 0-5 DEG C, and the vapor being further backing out in flue gas, the remaining hot water after heating passes through
Electric heating pump return afterheat-water pipe enters electric heating pump, and the electric heating pump waste heat water-circulating pump installed on electric heating pump return afterheat-water pipe is remaining
Hot water circuit provides circulation power；
Flue gas recirculation is as follows：After flue gas enters spraying filler absorption tower by gas inlet, it is uniformly distributed by flue gas flow equalizing plate,
Then absorption heat pump cooling section, electric heating pump cooling section, again liquid blocking section, hot arc are passed sequentially through, the cooling for completing flue gas takes heat, drop
Warm dehydration, washing desulphurization, flue gas reheat, the flue gas of reheating are discharged by exhanst gas outlet.
