Correlation analysis of spiral plate heat exchanger
When the spiral plate heat exchanger is used, if water/water is used as the heat transfer medium, the total heat transfer coefficient of the heat exchanger can reach 3~5 times of the heat transfer coefficient of the shell and tube heat exchanger, but the volume of the spiral plate heat exchanger is only about 30% of the shell and tube heat exchanger.
When the pressure loss of spiral plate heat exchanger is used, under the condition that the flow of heating carrier is equal, the pressure drop of heat exchanger is significantly reduced, and the water supply pressure is improved from 1.4mpa to 1.6mpa. Regarding the steam consumption of spiral plate heat exchanger, it should be noted that the steam consumption will be significantly reduced, because the original 1.11kg/s has been reduced to 0.97kg/s, and the steam should be saved per hour :(1.11-0.97)×3600/1000=0.504t.
Spiral plate heat exchanger heat transfer effect: in the case of reduced consumption of steam, heat transfer is greatly improved, water supply temperature will be improved from the original 92℃ to 95℃; Maintenance workload of spiral plate heat exchanger, before the transformation, after each operating cycle, because the heat exchanger scaling, heat exchange effect significantly reduced, need to dismantle, clean the heat exchanger, and in the maintenance, need to remove heat preservation, core pulling and other workload.
After two cycles of operation, the Murphy spiral plate heat exchanger was disassembled and assembled once, which was very convenient. All that was needed was to loosen the clamping screw to expose the plate and clean it. Concerning the floor space of the spiral plate heat exchanger, the plate heat exchanger is extremely compact in structure and the temperature reducer is small in size (300; L=1500), which is arranged above the plate heat exchanger and organically combined with the plate heat exchanger, covering only about 1/4 of the area of the shell and tube heat exchanger.
Of the spiral plate heat exchanger plate usually made trough or corrugated shape, the activities of the medium in the flow passage of a complicated three-dimensional structure of the event, its changing the activity direction and the speed, the bigger disturbance caused by the low Reynolds number (general Re = 50 ~ 200) can induce turbulence under (shell and tube heat exchanger insist on Reynolds number of 2000 or above).
