Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Principle of the present utility model is: except tube bank adopts the titanium alloy that corrosion resistance is strong, the base layer of tube sheet arranges the corrosion enhancement Layer that pure titanium makes, base layer can use common mild steel or cast iron etc., good corrosion resistance can be obtained, also there is enough intensity, can not the problems such as distortion be produced.
Embodiment:
As depicted in figs. 1 and 2, a kind of shell-and-tube heat exchanger (hereinafter referred to as machine), comprise housing 1, tube bank 2 and tube sheet 3, housing is rounded, multiple tube bank be parallel to each other is equipped with in inside, and housing two ends are respectively provided with a tube sheet, and tube bank two ends are fixed on tube sheet, be equipped with import and the outlet of fluid one between tube sheet to shell end, be respectively A mouth 11, B mouth 12, E mouth 15 and F mouth 16; Be provided with import and the outlet of fluid two between two tube sheets, be respectively C mouth 13, D mouth 14, G mouth 17 and H mouth 18; Tube sheet 3 comprises base layer 31 and corrosion enhancement Layer 32, and corrosion enhancement Layer 32 is arranged on the one side of corresponding A mouth 11, B mouth 12, E mouth 15 and F mouth 16, and the thickness of corrosion enhancement Layer 32 is 3 ~ 8mm, and its material is titanium; Corrosion enhancement Layer 32 is fixed by welding on base layer 31.
More flexible in order to use, the two ends of housing are all provided with tube sheet 3, and such fluid one can enter from any one end of housing.
Normal tube sheet 3 is that material is cylinder iron relatively good, and the stability of shape is best, but for the strong fluid of corrosivity, cast iron has been easy to regard to corrosion and damage.
So conventional stainless steel in addition, but stainless corrosion resistance neither be fine, and shape stability is not as cast iron.
So the corrosion enhancement Layer of titanium is welded in the creationary proposition of the utility model on the cast iron or stainless matrix of general employing.Welding method be adopt a kind of method of being explosive welding (EW), this be welding two kinds of unlike materials metal commonly use a kind of method, this is that those skilled in the art are accessible, no longer describes in detail.
In the present embodiment, the material of base layer 31 is cast iron.The shape stability of cast iron is better, so this is better mode.
In the present embodiment, the material of corrosion enhancement Layer 32 is industrially pure titanium.The mechanical property of industrially pure titanium is not as titanium alloy, but anti-corrosion capability is best, and the excellent Sheet Metal Forming Technology performance of industrially pure titanium and welding performance are extraordinary, so more easily process, do corrosion enhancement Layer also better.
In the present embodiment, the material of tube bank 2 is titanium alloy.Tube bank, owing to needing certain intensity, also needs corrosion resistance good simultaneously, so adopt titanium alloy to be preferred mode.
In the above-described embodiments, a kind of shell-and-tube heat exchanger that the utility model provides, except tube bank adopts the titanium alloy that corrosion resistance is strong, the base layer of tube sheet arranges the corrosion enhancement Layer that pure titanium makes, base layer can use common mild steel or cast iron etc., good corrosion resistance can be obtained, also have enough intensity, can not the problems such as distortion be produced.Its beneficial effect is: the corrosion resistance that well can utilize titanium, improves the service life of equipment, can overcome again the yielding problem of titanium.
Above is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
