The beneficial effect of the utility model:
The utility model can be used for cold and hot medium differential pressure and the bigger occasion of the temperature difference; Can utilize that mesohigh cold fluid (like water, air) comes recovery waste heat to reach energy-conservation purpose in low pressure exhaust gas hot fluid (like the flue gas) heating tube, the low pressure cold fluid (like air) that also can utilize pipe inner high voltage hot fluid (like steam) to come to flow through in the heated shell reaches the purpose of technological requirement.
The utility model is equivalent to a plurality of heat exchangers are become a heat exchanger, adopts simultaneously and can dismountable mode connect, and is convenient to the heat exchanging device and changes, and so not only economizes on resources but also reduces production costs.It is both having solved the adjustable problem of payload, and the heat exchanger tube high efficient heat exchanging, but tube bank combination in any and replacing have reduced the wasting of resources to greatest extent.
The utility model has improved heat exchange efficiency widely through at housing inlet or outlet eddy flow or shunting uniform device being set, and makes the thermic load of each tube bank even, helps prolonging operating flexibility and life-span.
When tube bank in the housing is when row or two rows; In the middle of a comb bundle connects up and down (tube bank about in the of 10 between) flow-stopping plate is set or long flow-stopping plate is set at intrafascicular of two combs (restrain between 16 front and back comb bundle remove change long flow-stopping plate into), increase substantially efficiency of heat exchanger.
The tube bank heat exchange pipe external surface of the utility model is the extra-high-speed fin; Fin height is the several times (for 0.5-6 times) of caliber; Usually fin height is below 0.5 times of caliber; Fin is to adopt high-frequency welding or soldering or compacting or mosaic texture, and the gear piece material can be consistent with tubing, also can be inconsistent.
The tube bank bandage of the utility model is flexible, can be single, and many arranged reach and effectively utilize waste heat, energy saving purposes.It has not only improved heat transfer efficiency, and safe and reliable, the separate dispersed placement in each position of flow process.
It is little to the utlity model has volume, is convenient to dismounting, regular maintenance, overhauls advantage easily, can improve thermic load 45%, and annual callable heat is amounted to several ten million yuan of the value of steam.
