Cylinder wraps up spiral plate after connecting integral cylindrical shell by being connected plate；This be connected plate include an arc sections and
The concentric furcation with the arc sections, the arc sections are connect with shell, and an end of arc sections and ipsilateral with it and should
Tail end of the end of the concentric furcation of arc sections respectively with spiral heat exchanger plates is connected；The conveyor screw wrapper sheet and outer housing
Cylinder connects at both ends.
The central tube is, to semi-circular tube structure is divided, centre is the partition for separating two-way fluid, partition outer rim and spiral plate
It is connected.
Equally distributed inclination slotted hole is opened up on the semicircle tube wall of the central tube.
The pressing plate of distribution hole is provided with out in inlet and outlet adapter tube on the outer housing cylinder.
The adapter tube bottom of thermal medium outlet and cold medium inlet is provided with stress relief grooves, so that conveyor screw wrapper sheet and heat are situated between
Matter outlet or cold medium inlet connection form flexible connection.
The outer housing cylinder is the cylindrical shell of only one longitudinal seam.
The outer housing cylinder is connected with vessel flange, which uses high neck W.N flange.
The present invention is by being revised as banjo fixing butt jointing for corner joint, the improvement of center tube structure, the structure of non-conventional type joint,
Stress relief grooves etc. are opened up at adapter tube to improve the partial structurtes of conventional helical sheet heat exchanger, are changed to by traditional mutation structure
Grading structure can make spiral heat exchanger bearing capacity reach 4 ~ 6.4MPa, and temperature resistant range is up to 400 DEG C, and then expands
The use scope of spiral heat exchanger.
The present invention is safe and reliable, bearing capacity is high, use scope is wide, quality controllable.

Specific embodiment
In conjunction with attached drawing, the invention will be further described.
Referring to Fig.1,2,3, a kind of high parameter spiral heat exchanger, mainly by thermal medium inlet 1, skull 2, vessel flange
3, gasket 4, outer housing cylinder 5, conveyor screw wrapper sheet 6, spiral plate 7, spacing column 8, central tube 9, cold medium export 10, in succession
Fishplate bar 11, thermal medium outlet 12, cold medium entrance 13, pressing plate 14 form.Thermal medium inlet 1 and cold medium outlet 10 are respectively set
On the skull 2 of rear and front end, it is tightly connected between skull 2 and outer housing cylinder 5 by vessel flange 3 and gasket 4；Central tube
9 are mounted on the center of outer housing cylinder 5, are equipped with spacing column 8, thermal medium outlet 12 and cold medium entrance between spiral heat exchanger plates 7
13 are arranged on outer housing cylindrical 5.
9 installation with one heart of outer housing cylinder 5 of central tube, the spiral plate 7 installed between the two, the 7 periphery packet of spiral plate
Conveyor screw wrapper sheet 6 is wrapped up in, which is made of two thin cylinders of semicircle, which passes through in succession
Fishplate bar 11(Fig. 3) the integral cylindrical shell of connection, the plate 11 that is connected includes an arc sections and concentric with the arc sections
Furcation, the arc sections connect with two thin cylinders of semicircle, at this time the radius of the thin cylinder of radius and semicircle of the arc sections
Adaptation, and an end of arc sections and the ipsilateral end of the furcation concentric with the arc sections tail with spiral heat exchanger plates 7 respectively
Hold butt welding.To improve the reliability of conveyor screw periphery connection.And the both ends of conveyor screw wrapper sheet 6 and outer housing cylinder 5
It welds so that conveyor screw wrapper sheet 6 is supported by outer housing cylinder 5 at both ends.
In the prior art, spiral plate and shell being directly welded to connect, due to the two wall thickness (shell thickness 38mm or so, and
Spiral plate only has 4mm-5mm) difference excessively great disparity, when there is pressure difference, heat exchanger failure easily by drawing crack, is caused in commissure.This
Pass through the transition of intermediate body convolutions body wrapper sheet in invention, the conveyor screw wrapper sheet and spiral plate are with thickness, even if being also not easy there are pressure difference
Drawing crack weld seam.
It is axial small since radially deformation is big for spiral plate, so conveyor screw wrapper sheet and outer housing cylinder are existed in the present invention
It is welded to connect at both ends, with the influence of Reducing distortion.
The central tube 9 is, to semi-circular tube structure is divided, centre is the partition for separating two-way fluid, partition outer rim and spiral plate
7 butt welding structures.In spiral-plate heat exchanger standard, the shortcomings that welding is all fillet weld, fillet weld is to be easy to draw when having pressure difference
Weld seam is split, and can not be carried out non-destructive testing.The present invention all uses butt-welded structure, not only increases conveyor screw center spiral shell
The reliability of rotating plate connection, is easy to detect weldquality.
Referring to Fig. 4, equally distributed inclination slotted hole is opened up on the semicircle tube wall of the central tube 9.Fluid passes in and out center
Guan Shi forms along axial zonal distribution effect, guarantees that internal flow is evenly distributed.
The pressing plate 14 of distribution hole is provided with out in inlet and outlet adapter tube on the outer housing cylinder 5.Pressing plate and conveyor screw packet
6 face contact of plate, effective support helix body wrapper sheet.
Referring to Fig. 5, the adapter tube bottom at thermal medium outlet 12 and cold medium entrance 13 is provided with stress relief grooves, so that spiral
Body wrapper sheet 6 and thermal medium outlet 12 or the adapter tube of cold medium entrance 13 form flexible connection, and the reliability of weld seam is higher.
The outer housing cylinder 5 is the cylindrical shell of only one longitudinal seam.Can two-sided welding, can detect, safely may be used
It leans on.
The outer housing cylinder 5 and 3 butt welding of vessel flange, improve the reliability of connection, which uses
High neck W.N flange.
