Example Embodiment
[0015] Specific implementation mode 1: Combination Figure 1-Figure 4 Explaining this embodiment, the flow-through heat exchange device of the urban sewage source heat pump system of this embodiment includes an outer shell 4, a left head 5, a right head 6, a sewage inlet 7, a sewage outlet 8, a medium inlet 9, and a medium outlet 10. , A plurality of head partitions 11 and a plurality of square tube rows or plywood layers 12, the plurality of square tube rows or plywood layers 12 are fixedly installed in the outer shell 4 from top to bottom to form a tube-shell assembly, a square tube In the row or plywood layer 12 is the medium flow channel 1, between two adjacent square tube rows or plywood layers 12, between the top square tube row or plywood layer 12 and the inner wall of the upper end plate of the outer shell 4 and between the bottom end Between the square tube row or plywood layer 12 and the inner wall of the lower end plate of the outer shell 4 is the sewage channel 2. Th...
Example Embodiment
[0016] Specific implementation manner two: combination Figure 1-Figure 3 To illustrate this embodiment, the height of the sewage flow channel 2 in this embodiment is 30 mm-60 mm, and the height of the medium flow channel 1 is 10 mm-20 mm. With this arrangement, the height of the medium flow channel is reduced by 50%-75%, and the height or volume of the flow-through heat exchange device is reduced by 25%-37.5%. The other composition and connection relationship are the same as in the first embodiment.
Example Embodiment
[0017] Specific implementation mode three: combination figure 1 To describe this embodiment, the height of the sewage flow channel 2 in this embodiment is 40 mm, and the height of the medium flow channel 1 is 20 mm. With this arrangement, the height of the medium flow channel is reduced by 75%, and the height or volume of the overflow heat exchange device is reduced by 37.5%. The other composition and connection relationship are the same as in the second embodiment.
[0018] The operating principle is: sewage containing suspended solids and other impurities enters from the sewage inlet 7, the first sewage channel from the inlet flows through each of the sewage channels in series, and flows out from the sewage outlet 8 of the outlet sewage channel. , See the flow route of sewage figure 1 The hollow arrow in the middle; the medium enters from the medium inlet 9, and the two or three or four parallel medium flow channels 1 at the inlet flow through the medium flow channel 1 in serie...
