Abstract
The utility model provides a sleeve pipe heat exchanger which comprises a sleeve pipe. The sleeve pipe is coaxially arranged and is composed of an inner pipe and an outer pipe. The sleeve pipe is composed of a sleeve pipe end, a sleeve pipe body and a sleeve pipe bending portion. The inner pipe is composed of an inner straight pipe and an inner bending pipe, the outer pipe is composed of an outer straight pipe and an outer bending pipe, the pipe end of the outer straight pipe of the sleeve pipe end is fixedly connected with the outer side of the inner straight pipe in a non-detachable and sealing mode, and the sleeve pipe body is composed of the inner straight pipe and the outer straight pipe; the sleeve pipe bending portion is formed in the mode that the inner bending pipe is sleeved with the outer bending pipe, the outer bending pipe is split along the central line, then the inner bending pipe is sleeved with the outer bending pipe, and the inner bending pipe is welded with the outer bending pipe. The inner bending pipe is in sealing butt joint with the inner straight pipe, and the outer bending pipe is in sealing butt joint with the outer straight pipe. The heat exchanger removes the leakage points and the unnecessary maintenance cost and material losses caused by the leakage, the manufacturing process is simplified, and the manufacturing cost and the manufacturing difficulty are greatly reduced.
Description
Technical field
The utility model belongs to chemical industry heat exchange field, particularly a kind of double-tube heat exchanger under the larger operating mode of the temperature difference.
Background technology
Mostly the double-tube heat exchanger of existing chemical field is to be comprised of concentrically ringed inside and outside two pipes, at present, double-tube heat exchanger for large temperature difference operating mode, its sleeve pipe pipe end adopts dismountable structure, as formed flange sealing structure by snap ring, flange, pad and gland, when this kind is connected to pipe end and is subject to affecting of the factors such as thermal expansion and vibration, the medium in outer tube easily leaks from joint, and in day-to-day operation, encapsulant also easily produces to lose efficacy because high temperature, burn into are aging and reveals.In addition, the bent tube section of sleeve pipe, internally the sleeve structure of bend pipe adopts bobbin carriage form, bobbin carriage pipe arrangement case lid, this structure very complex, manufacture difficulty is large, and cost is high.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of double-tube heat exchanger, has solved that pipe end is easily revealed, the baroque problem of bent tube section.
The utility model solves the technical scheme that its technical problem adopts: a kind of double-tube heat exchanger, the sleeve pipe being formed by inner and outer tubes that comprises coaxial setting, it is characterized in that: described sleeve pipe is comprised of sleeve pipe pipe end, sleeve pipe pipe shaft, sleeve pipe bent portion position, described inner tube is comprised of interior straight tube and interior bend pipe, and described outer tube is comprised of outer straight tube and outer bend pipe; The outer straight tube pipe end of described sleeve pipe pipe end is sealedly and fixedly connected by non-dismountable formula mode and interior straight tube outside; Described sleeve pipe pipe shaft is comprised of interior straight tube and outer straight tube; Described sleeve pipe bend pipe position is by excurvation pipe box on interior bend pipe, and described outer bend pipe is to be enclosed within on interior bend pipe again through being welded after center line is cut open; Described interior bend pipe docks with interior straight tube sealing, and described outer bend pipe docks with outer straight tube sealing.
Described non-dismountable mode is preferably and adopts end socket to weld.
Good effect of the present utility model: this patent has mainly improved the version of existing double-tube heat exchanger under larger temperature difference operating mode.Because shell side material is comparatively clean, in pipe, do not need to clean, therefore change the dismountable structure of existing structure pipe end into non-disconnectable formula structure, eliminated leakage point; From the operation maintenance of equipment, eliminated and leaked the unnecessary maintenance expense that brings and the loss of material.Environmental benefit, eliminated the leakage of material, stopped the pollution to environment.In addition, the structure of bent tube section is also reduced to outer bend pipe structure, in the situation that meeting equipment operation, has simplified manufacturing process, and manufacturing cost, manufacture difficulty all have substantial degradation.

Fig. 2 is a kind of double-tube heat exchanger sleeve pipe of the utility model bent portion bit architecture schematic diagram.
In figure: 1. interior straight tube, 2. outer straight tube, 3. pipe cap, 4. interior bend pipe, 5. outer bend pipe.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is elaborated.
See figures.1.and.2, the utility model preferred embodiment provides a kind of double-tube heat exchanger, the sleeve pipe being formed by inner and outer tubes that comprises coaxial setting, it is characterized in that: described sleeve pipe is comprised of sleeve pipe pipe end (Fig. 1), sleeve pipe pipe shaft, sleeve pipe bend pipe position (Fig. 2), described inner tube is comprised of interior straight tube 1 and interior bend pipe 4, and described outer tube is comprised of outer straight tube 2 and outer bend pipe 5; Outer straight tube 2 pipe ends of described sleeve pipe pipe end are sealedly and fixedly connected by non-dismountable formula mode and interior straight tube 1 outside; Described sleeve pipe pipe shaft is comprised of interior straight tube and outer straight tube; Described sleeve pipe bend pipe position is enclosed within on interior bend pipe 4 by outer bend pipe 5, and described outer bend pipe 5 is to be enclosed within on interior bend pipe 4 again through being welded after center line is cut open; Described interior bend pipe 4 docks with interior straight tube 1 sealing, and described outer bend pipe 5 docks with outer straight tube 2 sealings.
Described non-dismountable mode is for adopting end socket to weld.
During manufacture, first by inside and outside straight tube by being nested with one heart, outer straight tube pipe end, by pipe cap 3 and interior straight tube 1 welding, adopts Welding Structure to eliminate the leakage point of existing structure; Bent tube section can first dock interior bend pipe with interior straight tube, outer bend pipe is enclosed within after cutting open by center line on interior bend pipe and goes and be welded into integral body again, and then docks with outer straight tube, now should consider the swell increment that the temperature difference causes, according to swell increment, adjusts inside and outside bend pipe centre-to-centre spacing.The method is simple in structure, and can ensure the quality of products, and greatly reduces manufacture difficulty and the cost of existing structure.
Above-described is only preferred embodiment of the present utility model; institute is understood that; the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof; and be not used in and limit protection domain of the present utility model; all any modifications of making, be equal to replacement etc., within all should being included in protection domain of the present utility model within thought of the present utility model and principle.
