Embodiment 1
[0024] This embodiment provides a boiler waste heat recovery system, such as figure 1 As shown, the boiler waste heat recovery system includes a boiler 1 , waste heat recovery equipment, a heat exchanger 2 and a steam tank 3 . The waste heat recovery equipment transfers the waste heat of the boiler to the steam tank 3 through the heat exchanger 2, heats the cold water in the steam tank 3 and converts it into steam and stores it in the steam tank 3.
[0025] The waste heat recovery equipment includes a heat exchange tube assembly 4 arranged on the outer periphery of the boiler 1 , wherein the heat exchange tube assembly 4 , the first circulation pump 5 and the heat exchanger 2 form a refrigerant circulation loop. The heat exchange tube assembly 4 includes a first annular pipe 41 surrounding the upper part of the boiler 1, a second annular pipe 42 surrounding the lower part of the boiler 1, and a plurality of straight pipes 43 connecting the first annular pipe 41 and the second ...
Embodiment 2
[0035] This embodiment provides a boiler waste heat recovery system, such as figure 2 As shown, the boiler waste heat recovery system includes a boiler 1 , waste heat recovery equipment, a heat exchanger 2 and a steam tank 3 . The waste heat recovery equipment transfers the waste heat of the boiler to the steam tank 3 through the heat exchanger 2, heats the cold water in the steam tank 3 and converts it into steam and stores it in the steam tank 3.
[0036] The difference is that, in this embodiment, a filter device 10 is provided on the outlet pipeline of the cold water outlet of the steam tank 3 . By setting the filter device 10, the water in the pipeline can be filtered to further avoid the blockage of the pipeline and ensure the reliability of use.
