Summary of the invention

In order to overcome the trouble that existing chemical pipeline is made chuck, pipe was as the way of working fluid in the main heating pipe in the utility model adopted, in order to replace the making of external jacket, its advantage is, when interior pipe passes to superheated vapor or heat conduction wet goods medium, during in order to heated working fluid, because interior pipe is all to be immersed in the working fluid, thereby the outer surface of interior pipe is heated fluid directly, the employing chuck mode that compares is direct, need not to want first heated fluid pipe outer wall as chuck, conduct heat to fluid again, its biggest advantage is simultaneously, a large amount of heat radiations that can not have the jacket pipe outer wall as chuck take place, designing and calculating shows: the chuck mode of heating, if do not calculate outer other thermal insulation layer effect, its heat of 4/5ths has been lost, but pipe mode of heating in adopting, the less than 1/10th of San Shiing then, if all adopt same external insulation layer, then chuck is 1: 4.5 with the ratio of the heat utilization efficiency of interior pipe heating.In certain colder place, perhaps in order to quicken the preheating to pipeline at the beginning of going into operation, the outside also can add outer semicanal or the coiling volute is made assistant heating.

The technological scheme that its technical problem that solves the utility model adopts is: pipe-line equipment is by the working fluid pipe, interior pipe, inner pipe joint, auxiliary outer semicanal is formed, concrete structure is, pipe in the working fluid pipe, welding one, its two ends curve vertical elbow, the single head radial dimension that interior pipe adds elbow is slightly less than the working fluid bore, can put into the working fluid pipe easily with pipe in guaranteeing, on working fluid tube wall homonymy or 180 degree directions, respectively open a hole, perforate is done by interior external diameter of pipe, and guarantee to become to weld smoothly, advance, the inner pipe joint of outlet port weld heating medium, inner tube diameter is got DN5-DN10 usually, for king-sized working fluid pipeline, fast in order to heat, the desirable DN15-DN32 of inner tube diameter even bigger, also available tubule coiling pipe, to improve heating surface, perhaps outer wall of inner tube straight length roll printing triangle straight burr, to increase heating surface area, for bigger working fluid pipeline, interior pipe is without elbow, behind the lengthening of two ends, directly welding is laterally advanced, the outlet inner pipe joint is to increase heat transfer area, described auxiliary outer semicanal, just add auxiliary preheating again at needs working fluid pipe, the situation of insulation, its structure is: with the close pipeline of work fluid hose, cut in half, the thermal medium that is welded on the working fluid pipe advances, the outlet port, and UNICOM, iff for preheating and insulation, twine twist outside the working fluid pipe with tubule, constitute outer assistant heating, insulation.

The beneficial effects of the utility model are, can save the heat supplied 50-60% of heating pipe, can save pipeline material 60-70%, processing and fabricating is convenient than jacket pipe, simple simultaneously, when particularly having measuring hole, more convenient, weld more reliable, when saving the Welder 50%, therefore total manufacture cost reduces about 40%.Using economic benefit to improve 40%, mainly is to save heat energy, significantly reduces the pipe leakage fault, and maintenance and maintenance are convenient.Inner tube material is generally stainless steel, and some situation also can use copper pipe, aluminum pipe or Coating Steel Pipe to make.
