The beneficial effects of the utility model are as follows:
The utility model is arranged in the top on absorption tower with flue gas heat exchange device (GGH), and the heat exchanger hot junction is last, and the heat exchanger cold junction is down.
This arrangement has following advantage:
(1), because the flue gas heat exchange device directly is arranged in absorption tower top, saved the place of flue gas heat exchange device and corresponding contact flue in the conventional layout, floor space less than routine arrange 1/2nd.
(2), at last arrangement, the former dust in flue gas direction of motion is consistent with gravity direction, has reduced the dust deposit on GGH heat exchange element surface in following heat exchanger hot junction for GGH heat exchanger cold junction, reduces resistance and system's power consumption.Even deposit, also be easier to clean by soot blower.
(3), because the absorption tower stock tank is communicated with distance with GGH far away, the situation that moisture enters GGH is alleviated, and effectively prevents wet grey generation, the minimizing operation troubles.
(4), the control of absorption tower operation liquid level can not influence the operation of GGH.
The utility model passes through to improve flue to be arranged, makes it to be applicable to the desulphurization system of lack of space, and efficiently solves the problem of the stifled ash of GGH, resistance increase, can be widely used in process for flue gas desulfurization by limestone/lime-gypsum wet field, thermal power plant.
