具体实施方式 Detailed ways
以下结合附图和具体实施例，对本实用新型做进一步的详细叙述。 Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
如图1所示，锅炉余热回收加热系统，包括输烟管1、余热回收装置2和排烟囱3，在排烟囱3与余热回收装置2之间设有引风机4，在引风机4作用下锅炉排出的高温烟气经输烟管1、余热回收装置2，由排烟囱3排出，余热回收装置2上安装有冷水进口管和热水出口管，热水出口管通过管道与一保温热水箱5相连，在冷水进口管的管道上还设有一循环水泵6。 As shown in Figure 1, the boiler waste heat recovery heating system includes a smoke pipe 1, a waste heat recovery device 2 and a chimney 3, and an induced draft fan 4 is installed between the chimney 3 and the waste heat recovery device 2. Under the action of the induced draft fan 4 The high-temperature flue gas discharged from the boiler passes through the smoke pipe 1, the waste heat recovery device 2, and is discharged from the chimney 3. The waste heat recovery device 2 is equipped with a cold water inlet pipe and a hot water outlet pipe. Box 5 links to each other, also is provided with a circulating water pump 6 on the pipeline of cold water inlet pipe.
本实施例中余热回收装置2为一空气源热泵热水加热装置。 In this embodiment, the waste heat recovery device 2 is an air source heat pump hot water heating device.
在输烟管1和排烟囱3之间设有旁路输风管7，输烟管1、排烟囱3和旁路输风管7上各设有一风阀8。 A bypass air delivery pipe 7 is provided between the smoke delivery pipe 1 and the chimney 3, and a damper 8 is respectively provided on the smoke delivery pipe 1, the chimney 3 and the bypass air delivery pipe 7.
