Embodiment Construction
[0015] Such as figure 1 , 2 , 3, and 4, the intermediate water enters from the intermediate water inlet pipe 1, and then passes through the intermediate water side flow channel 4, the left intermediate water diversion pipe 3, the right intermediate water diversion pipe 10, and the intermediate water outlet pipe 2 The sewage enters from the sewage inlet pipe 6, passes through the sewage pipe box 8 on the left side, the sewage special flow channel 5, the sewage pipe box 11 on the right side successively, and then flows from the sewage pipe box 11 on the right side to the next sewage special flow channel 5, Finally, it is discharged from the sewage outlet pipe 7; the flow direction of the intermediate water and the sewage is always opposite, and the heat is exchanged countercurrently.
[0016] Figure 5 In the shown embodiment, the special flow channel 5 for sewage between the left side sewage pipe box 8 and the right side sewage pipe box 11 has a trapezoidal upper part and a p...

The invention provides a heat exchanger special for a sewage source heat pump. Dirt with optional sizes in sewage can pass through the heat exchanger, and a filter anti-blocking device is not required to be arranged at the front end of an entire heat exchange system. The entire heat exchanger device comprises an intermediate water inlet tube, an intermediate water outlet tube, an intermediate water baffling tube, an intermediate water side flowing way, special sewage flowing ways, a sewage inlet tube, a sewage outlet tube, sewage channels and a shell, wherein intermediate water enters the intermediate water inlet tube, and sequentially flows through the intermediate water side flowing way, the intermediate water baffling tube and the intermediate water outlet tube; sewage enters the sewage inlet tube, sequentially flows through a left sewage channel, one of the special sewage flowing ways and a right sewage channel, then is baffled to the next special sewage flowing way, and finally is drained out of the sewage outlet tube; and the flowing direction of the intermediate water is always opposite to that of the sewage, so that countercurrent flow is formed. The special sewage flowing ways have structures with narrow tops and wide bottoms, the density of the sewage is greater than that of water in a flowing process of the sewage, and the sewage can flow at lower ends of the special sewage flowing ways smoothly.
Description
technical field [0001] The invention relates to a heat exchange device, in particular to a special heat exchanger for a sewage source heat pump which utilizes a sewage source as a cold and heat source. Background technique [0002] In recent years, my country has vigorously advocated energy conservation and emission reduction, and encouraged the development and use of energy-saving products. Among them, urban development and urban population increase make the consumption of heating in winter and cooling in summer gradually become an important aspect of energy consumption. For this reason, many energy-saving products have been produced: heat pumps solve part of the heating and cooling requirements, but due to the distribution of water resources and the site constraints of ground source heat pumps, they cannot be widely used. The use of sewage sources can alleviate the current energy shortage situation, has a good energy-saving effect, saves the increasingly scarce fresh wate...
