From the fresh water hot steam (high temperature fluid) that last effect of the multiple-effect distillation device of seawater desalination system generates from net
The entrance 23 of shape pipeline 2 enters, and punishes and flows in entrance 23, one dividing into three, separately flows into the first heat exchange network management 21, second heat exchange net
The heat exchange network management 21 of pipe 22, first；
Hot steam (high temperature fluid) is separately flowing into the first heat exchange network management 21, second heat exchange heat exchange network management of network management 22, first
After 21, in the case where the internal diameter of the pipeline of intake velocity and each heat exchange network management is constant, then the first heat exchange network management 21, second are changed
Pressure in the heat exchange network management 21 of heat supply network pipe 22, first is lower than pressure at the entrance 23 of mesh duct 2；The low then gas flow rate of air pressure
It becomes faster, i.e. hot steam (high temperature fluid) intake velocity at the entrance 23 of mesh duct 2 becomes faster, and can accelerate so new and old in pipeline
The change of gas；
Hot steam (high temperature fluid) after carrying out heat exchange with the material seawater (cryogen) in circulation duct 1, steam by heat
Vapour (high temperature fluid) condensation becomes liquid and flows out from the outlet of mesh duct 2 24, will form water at the outlet 24 of mesh duct 2
Envelope；Due to belonging to gas intersection at the outlet 24 of mesh duct 2, when 24 flow rate of liquid of the outlet of mesh duct 2, one timing, gas
Body gathers, and air pressure is got higher, and will push the liquid flowing at the outlet 24 of mesh duct 2, is conducive to accelerate to collect fresh water；
During heat exchange, thread a pipe in material seawater (cryogen) first exchange heat network management 21 from the first of side
The first mesh 211 (two sides of the first heat exchange 21 pipeline of network management) flow to the second heat exchange network management 22 of middle, in the process,
The material seawater (cryogen) flowed through from the first mesh 211 of the first heat exchange network management 21 can be by the pipeline of the second heat exchange network management 22
Stopped, so that second mesh 221 (second heat exchange network management 22 pipeline of the material seawater (cryogen) from the second heat exchange network management 22
Two sides) flow to the other side first heat exchange network management 21；During flowing, material seawater (cryogen) can again
Stopped by the first heat exchange 21 pipeline of network management, material seawater (cryogen) shunts again；Thus reciprocal, material seawater (low temperature
Fluid) flowing velocity can slow down, can make in this way material seawater (cryogen) can with mesh duct 2 (first heat exchange net
Pipe 21, second exchange heat network management 22) heat exchange time of contact it is longer, improve heat exchange efficiency.
To sum up, the heat exchanger of the utility model has the following beneficial effects: compared with prior art
Since the mesh duct 2 for passing through high temperature fluid in heat exchanger is set to the circulation duct 1 for passing through cryogen
It is interior, and the first mesh 211 and the second heat exchange net for passing through cryogen on the first heat exchange network management 21 of mesh duct 2
The second mesh 221 for passing through cryogen on pipe 22 is staggered, so, the first heat exchange network management of mesh duct 2
21 and second being overlapping for heat exchange network management 22 can provide resistance to the flowing of cryogen flowed through from circulation duct 1,
There is the effect for slowing down flow velocity and flow-disturbing to cryogen；Moreover, the staggeredly weight of the first heat exchange network management 21 and the second heat exchange network management 22
It is folded that mesh duct 2 can also be made to make full use of space in the pipe of circulation duct 1, to improve cryogen and height to the maximum extent
The contact heat-exchanging area of warm fluid, and then improve the heat exchange efficiency of heat exchanger；
