Embodiment 1
[0032] As shown in Figures 1, 6, 7, and 8.
[0033] A thermal energy recovery system for heated waste water, comprising a waste water filtering device 1, a heat exchanger 2 (a plate heat exchanger may be used, the same below), a hot water boiler 3, the water inlet end of the waste water filtering device 1 is connected to a hot sewage source, Its output is connected to the water inlet end of the hot water side of the heat exchanger 2 through the valve 15, the variable water pump 5, and the valve 9, and the water outlet end of the hot water side of the heat exchanger 2 is connected to the discharge pipe through the valve 12. A recoil steam valve 7 is installed on the pipeline between the outlet end of the hot water side of 2 and the valve 12, so as to carry out back flushing when the heat exchanger 2 is cleaned. A valve 13 for supplying clear water during cleaning is also installed on the pipeline between the water outlets on the heat source water side. In addition, in order to ...
Embodiment 2
[0036] As shown in Figures 2, 6, and 7.
[0037] A thermal energy recovery system for heated waste water, comprising a waste water filter device 1, a heat exchanger 2, and a hot water boiler 3, the water inlet end of the waste water filter device 1 is connected to a hot sewage source, and its output passes through a valve 15, a variable water pump 5, and a valve 9 is connected to the water inlet end of the hot water side of the heat exchanger 2, the water outlet end of the hot water side of the heat exchanger 2 is connected to the discharge pipe through a valve 12, and the water outlet end of the hot water side of the heat exchanger 2 is connected to the valve 12 The backflush steam valve 7 is installed on the pipeline between them, so as to backwash the heat exchanger 2 when cleaning. A valve 13 for supplying clear water during cleaning is also installed. In addition, in order to protect the normal operation of the equipment during cleaning, a short-circuit discharge pipe 6 i...
