Abstract
The utility model relates to a heat-exchange device of a tube bank dryer, which comprises a heat exchange tube, a shell, a baffle plate and a steam pipe box, in the scheme, a teflon coating layer is arranged on an outer layer of the heat exchange pipe within one third of the length of the heat exchange tube close to a material inlet end, the dry film thickness of the teflon coating layer is 140 to 160 umm, and the optimum dry film thickness of the teflon coating layer is 150umm. The heat-exchange device can effectively attenuate the corrosion of sulfurous acid which is contained in corn fiber and protein powder to the heat exchange tube, and can prolong the service life of the dryer.
Description
Technical field:
The utility model relates to a kind of heat-exchanger rig, relate in particular to a kind of heat-exchanger rig of pipe bundle drier.
Background technology:
In the starch industry, must soak with sulfurous acid before the corn fragmentation, so contain a large amount of sulfurous acid in zein fiber after broken apart and the albumen powder.In dry run, sulfurous acid can corrode heat exchanger tube, thereby shortens the service life of drying machine.Because zein fiber and albumen powder are when entering pipe bundle drier, moisture content is bigger, has stronger adhesiveness, very easily sticks on the heat exchanger tube, makes heat exchanger tube be more vulnerable to corrosion.Practice shows, is used for the drying machine of dry zein fiber and albumen powder, and its heat exchanger tube is near the easiest adhesion zein fiber of feed inlet end and albumen powder, and therefore corrosion is the most serious.For solving etching problem, what adopt at present is to use heat exchanger tube instead corrosion that stainless steel tube weakens sulfurous acid, and using stainless steel tube instead will certainly raise the cost, thereby influences the popularization of pipe bundle drier, and this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model, be exactly at the existing in prior technology deficiency, a kind of technical scheme of heat-exchanger rig of pipe bundle drier is provided, this scheme cost is lower, and can effectively weaken the corrosion of contained sulfurous acid exchange heat pipe in zein fiber and the albumen powder, prolong the service life of drying machine.
This programme is realized by following technical measures: the heat-exchanger rig of this pipe bundle drier, comprise heat exchanger tube, housing, dividing plate, steam bobbin carriage, the characteristics of this programme are that the heat exchanger tube skin in heat exchanger tube is sentenced near feed inlet end heat exchanger tube length 1/3rd has the Teflon dope layer, it is 140-160 μ m that the concrete characteristics of this programme also have the build of Teflon dope layer, specifically, the build of Teflon dope layer is 150 μ m.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, heat exchanger tube skin in heat exchanger tube is sentenced near feed inlet end heat exchanger tube length 1/3rd has the Teflon dope layer, the build of Teflon dope layer is 140-160 μ m, this Teflon dope layer has good heat endurance, under a fixed load, has wear-resistant and inadhesive performance, and corroded by medicine, can effectively weaken the corrosion of contained sulfurous acid exchange heat pipe in zein fiber and the albumen powder, prolong the service life of drying machine.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
Fig. 2 is the enlarged drawing that A is ordered among Fig. 1.
Among the figure, 1 is housing, and 2 is the steam bobbin carriage, and 3 is dividing plate, and 4 is heat exchanger tube, and 5 is the Teflon dope layer.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
A kind of heat-exchanger rig of pipe bundle drier, heat exchanger tube (4), housing (1), dividing plate (3), steam bobbin carriage (2) are arranged, heat exchanger tube (4) skin in heat exchanger tube in this programme (4) is sentenced near feed inlet end heat exchanger tube (4) length 1/3rd has Teflon dope layer (5), the build of Teflon dope layer (5) is 140-160 μ m, and the build of best Teflon dope layer (5) is 150 μ m.
Claims (3)
1. the heat-exchanger rig of a pipe bundle drier comprises heat exchanger tube, housing, dividing plate, steam bobbin carriage, it is characterized in that: the heat exchanger tube skin in described heat exchanger tube is sentenced near feed inlet end heat exchanger tube length 1/3rd has the Teflon dope layer.
