The half namely hot type floats a dish tube heat exchanger a,
All sayFloat a dish tube the heat exchanger is absorbing international advanced technical foundation up, the independence develops of the new generation change a hot machine, with structure novel, outstanding function, the gearing is extensively simple, Be applied to the production of industrial and public building, live hot water system.
In recent years, along with the Chan wood’s thorough research in floating a dish tube to transmit heat mechanism, that product continuously gets an improvement and perfect, it changes a hot efficiency further exaltation, structure gradually science, reasonable.
Two, structure and work principle
1, structureThe CLFJ type heat exchanger constitutes to°from the hull body, dish tube and connector.
2, work principleThe steam gets into a hull body of sign inside the tube, even assign to each hang an arm dish tube, congealed become congealed water to eject after letting out calories;Water after getting into a hull body, after blocking a plank function under the dispersion, one by one in order heating through several dish tubes, from pipe line derivation.
The steam is in the dish take care of inside the high speed flow, it leaves a heart function dint push dish tube creation Gao repeatedly float and urge the tube to outside be heated marine products to living a perturbation and break a layer between tube-waters to spread a hot layer and enhanced convection to change hot;Change hot coefficient to consumedly raise, the vapor-water changes hot of transmit heat coefficient can be up to a 2600 kcals/m 2 · hs ·℃;Water-water changes hot of transmit heat coefficient to reach to a 1700 kcals/m 2 · hs ·℃.
3, material and the work pressure ① dish tube take care of for red copper and take care of the distance as hot Mei passage.Work pressure when hot Mei was heat water<1.6 MPas, when the hot Mei was a steam work pressure<0.6 MPas;②The hull body is carbon steel or stainless steel, the hull distance is added hot water passage.The work pressure divides a 0.6, 1.0, 1.6 MPas 3 kind.Have special request to the material and the work pressure of, can make to order.
Three, function characteristics
1, transmit heat coefficient Gao;
2, auto in addition to dirt:attach knot at change the dirty mark on the hot tube to transmit heat ability bad, the hot bulge is cold to shrink a far not equal to copper, very easy at heat in response to take off to drop down from the copper tube under the dint function.In the meantime, dish’s taking care of the slight collision of will also accelerate sheding off of dirty mark;
3, apply scope widely:the hot Mei can adopt steam or hot water;
4, the physical volume is small and install, transport, maintain convenience;
5, the resistance is small:The hull distance resistance loses ≤ 20 kpasTake care of the distance resistance loss ≤ 35 kpas
Four, install usage elucidation
1, CLFJ type the heat exchanger install in brief, needs to mount a homologous valve door, appearance and piping then;
2, the beard installs safe valve(should match 《the pressure container safe technique inspect regulations 》) or the design inflation tube box;
3, if the part accumulates dirt to automatically shed off, can adopt a hot impact method:(a)line up clean hull memory water and congealed water inside the tube;(b)Open steam valve to the heating tube to have sound;(c)open water valve cooling to heat a tube;Again operate 3-4 times, will accumulate dirt in addition to clean;
4, in order to ensure to supply water fluid matter, should line up every week dirty once;
5, hull body in response to the heat preservation, the gearing should considered that the check fixs spaced while taking seat.
