摘要

PPROBLEM TO BE SOLVED: To provide a high-dust exhaust gas heat recovery processing device for being compactly disposed in a flue of a high dust concentration atmosphere, and exchanging heat at a high flow rate. PSOLUTION: In this exhaust gas processing device wherein the air B is heated by heat exchange with an exhaust gas 23 discharged from a coal-fired boiler 11 by an air preheater (AH) 12, then supplied to a dust collecting device (dry type EP) 14 to remove dust components, desulfurized by a desulfurizer 15, and discharged to the external as a purified gas through a chimney, a thin box-type heat recovering device 20 provided with a plurality of thin heat exchanging portions along the flowing direction of the exhaust gas 23, is disposed between the air preheater 12 and the dust collecting device 14, and a liquid film for heat exchange is allowed to flow down on inner wall surfaces of the thin heat exchanging portions.

要解决的问题：提供一种高粉尘废气热回收处理装置，该装置紧凑地布置在高粉尘浓度气氛的烟道中，并以高流量进行热交换。

解决方案：在该废气处理装置中，空气B通过空气预热器（AH）12与从燃煤锅炉11排放的废气23进行热交换而被加热，然后提供给集尘装置（薄型箱式热回收装置20，其具有通过脱硫装置15脱硫并通过烟囱作为净化气体排出到外部的灰尘成分的薄壁箱式热回收装置20，该薄箱式热回收装置沿流动方向具有多个薄热交换部。另外，在空气预热器12与集尘装置14之间配置有排气23的排气方向，在薄壁的热交换部的内壁面上，使热交换用的液膜流下。
