Zusammenfassung: | The utility model relates to the technical field of heat recovery, and discloses an exhaust steam heat recovery device which is characterized in that a heat exchange box is connected with a purification box through a communicating pipe, the upper end of a box frame of the purification box is connected with a sealing end cover, a heat recovery mechanism is arranged in the box frame of the heat exchange box, and a flue gas purification mechanism is arranged in the purification box. According to the utility model, through the sleeving combination of the heat exchange coil pipe and the hot air cylinder in the heat recovery mechanism, under the spiral flow guide of the flow guide plate with the spiral structure, the waste heat and cold water of the steam turbine can be subjected to all-directional heat exchange heating work, so that the heat exchange area of hot air and cold water can be increased on one hand, and on the other hand, the waste heat exchange continuity can be improved; and through flue gas filtratio |
