As shown in Figs 1-4, a kind of heat exchanger evaporation tube flow-guiding structure, more evaporation tubes, two including running through 2 both ends of heat exchanger chamber
A diversion cavity 4 for being respectively communicated with the more evaporation tube both ends；Equipped with muti-piece by more evaporation tubes in the diversion cavity 4
The partition 41 that end separates, so that sewage flows through multiple evaporation tubes according to certain flow direction and sequence.Specifically, as schemed
Shown in 2 and Fig. 3, the diversion cavity at the end is divided into 3 sub-chamber 401, middle and upper part Liang Ge sub-chamber by the multiple partitions of one end
401 are respectively communicated with the evaporation tube of 1/4 quantity, and above-mentioned two sub-chamber is respectively equipped with water inlet 7 and water outlet 8, and lower part
A sub-chamber be communicated with the evaporation tube of 1/2 quantity；The partition of the other end by the diversion cavity at the end be divided into left and right 2 it is identical
The sub-chamber 401 of size, is respectively communicated with the evaporation tube of 1/2 quantity.By taking a kind of more specifically embodiment as an example, such as Fig. 4
It is shown, it is assumed that one shares 100 evaporation tubes, then, the sub-chamber A and sub-chamber B of one end have been respectively communicated with 25 evaporation tubes, point
Cavity C is communicated with 50 evaporation tubes, and the sub-chamber D of the other end and sub-chamber E have been respectively communicated with 50 evaporation tubes.Water conservancy diversion is former
Reason: sewage enters sub-chamber A from water inlet 7, flows subsequently through 25 evaporation tubes, flows out from 25 evaporation tubes on the top sub-chamber D,
Then other 25 evaporation tubes that the lower part sub-chamber D is flowed by sub-chamber D, then from 25 evaporation tubes of sub-chamber's C left part
Outflow flows into 25 evaporation tubes of sub-chamber C right part, then 25 evaporation tube streams from the lower part sub-chamber E after sub-chamber C
Out, 25 evaporation tubes on the top sub-chamber E are flowed into after sub-chamber E, are then flowed out from 25 evaporation tubes of sub-chamber B, most
Afterwards from the water outlet discharge of connection sub-chamber B.In whole process, sewage has flowed through the distance of 4 times of evaporation length of tube, is intaking
Mouthful pump power it is certain in the case where, a possibility that flow velocity of the sewage in evaporation tube greatly improves, reduce blocking, simultaneously
Water conservancy diversion is carried out by sub-chamber at the both ends of evaporation tube, avoids the problem of bend pipe is easy blocking, so that heat exchanger
It works more stable and highly efficient, while reducing the frequency and cost of clean and maintenance.
It should also be noted that, since this heat exchanger can be used for sewage, so the caliber to evaporation tube is also wanted
It asks, under a kind of embodiment, the diameter of evaporation tube is 25.4mm, and the evaporation tube of preferably inner wall smooth, to avoid more substantially
Long-pending impurity results in blockage, and pipe thickness is 1.18mm, to combine heat exchange efficiency and structural strength.
