Abstract
A spiral baffle plate belongs to the field of fluid heat-exchange equipment. The spiral baffle plate comprises a core tube, a spiral plate arranged around the core tube and through hole arranged on the spiral plate, wherein one end of the core tube is fixedly connected with a cover plate; the spiral plate is integrated with the core tube, thereby forming the spiral baffle plate. The whole spiral baffle plate can increase the flow speed of medium in a shell, guarantee a smooth flow without dead angles and improve heat exchanging efficiency of heat-exchange tubes; and the spiral baffle plate is fixedly connected with the cover plate, so both assembling and disassembling operations are quite convenient and easy.
Description
Technical field
The utility model relates to a kind of deflection plate, is used in particular for the spirality deflection plate.
Background technology
Vortex or helical flow are the effective means of augmentation of heat transfer always, change into the conception that the mobile angle of helical form has produced spiral baffle heat exchanger from shell fluid by vertical or snakelike lateral flow direction, the present segmental baffle that generally uses, the drawback of segmental baffle is along the journey pressure drop bigger, is prone to flow blind angle, by-pass flow, leakage current, and the heat exchanger tube vibration is induced in easily fouling, higher velocity of medium, shortens heat exchanger service life.
Summary of the invention
The purpose of this utility model is to solve the problems of the technologies described above, and provides a kind of simple in structure, conducts heat evenly deflection plate easy for installation.
Technical solution of the present invention is: described helical baffles comprises the core pipe, around the spiral plate body of core pipe setting be arranged on through hole on the spiral plate body; One end of described core pipe is fixedlyed connected with cover plate; One end of described core pipe arranges installing hole.
One end of core pipe arranges installing hole, is used for fixedlying connected with cover plate, as long as will fixedly connected cover plate during installation with the core pipe of helical baffles, packs into together then in the housing, cover plate is connected with housing seal again, and the whole erection process is just very simple.
As preferably, described core pipe and spiral plate body adopt spiral plate body and the core pipe of integrated through injection molding moulding to connect into an integral body, and whole helical baffles can be combined by a plurality of spiral plate bodys, so just can guarantee every spacing unanimity between the spiral plate body.Some spiral plate body is the multi-disc assembled formation, but the spacing that can occur between the spiral plate body after the assembling is inconsistent, and assembles and relatively expend time in, and goes wrong and also will take apart, and repairs trouble.
As further preferred, the outer circumferential edges of described spiral plate body is provided with thickness less than the shirt rim of described helical baffles.Avoided by-pass flow, problems such as leakage current.Guarantee that simultaneously the spirality deflection plate is unlikely to unsettled in cylindrical shell, avoid the vibration of heat exchanger tube, increase heat exchanger service life.
As further preferred, the cross section that described through hole is axial with respect to vertical described heat exchanger tube be projected as circle.Because general heat exchanger tube all is circular, in order to pass heat exchanger tube, so will guarantee the precision of the through hole on the spiral plate body of curved surface.
As preferably, the helical corrugation of described helical baffles is shaped as the consecutive periods function, helical baffles is the deflection plate that the continuous helical sheet constitutes or the deflection plate that is formed by a plurality of flights overlap joints, and helical baffles is that single coil configuration, double-spiral structure or many helical structures and itself and shell side import and shell side export single-screw of corresponding composition, double helix or how screw type shell-side circulation passage.
The utility model beneficial effect is: by the spirality deflection plate of the technical program, spiral plate body for the integrated through injection molding moulding, with horizontal baffling mode ratio, there is not the stagnation dead band, when improving the coefficient of heat transfer, reduce dirt deposition, thermal resistance is stable, can make heat exchanger be in efficient running status always.The constraint of helical baffles exchange heat pipe is better than segmental baffle in addition, has reduced tube bundle vibration, has prolonged the service life of equipment.And helical baffles is fixedlyed connected with cover plate, is that installation or dismounting are all very convenient quick like this.

Among the figure: 1-housing, 2-cover plate, 3-spirality deflection plate, 31-spiral plate body, 32-core pipe, the 33-through hole, 321-installing hole, 331-shirt rim, 4-bolt, the import of 5-tube side medium, 6-tube side media outlet, 7-heat exchanger tube, the import of 8-shell side medium, 9-shell side media outlet.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
Embodiment 1, and as illustrated in fig. 1 and 2, a kind of spirality deflection plate comprises the shell 1 of an end opening, can seal the end plate 2 of shell 1 opening, also is provided with sealing ring between end plate 2 and the shell 1.Tube side medium inlet 5 and tube side media outlet pipe 6 are arranged on the end plate 2, and tube side medium inlet 5 and tube side media outlet pipe 6 are connected to the two ends of heat exchanger tube 7.Shell side medium inlet 8 and shell side media outlet 9 also are set on the shell 1.Be provided with helical baffles 3 in shell 1 inner chamber.The spiral plate body 31 that described helical baffles 3 comprises core pipe 32, arrange around core pipe 32 and be arranged on through hole 33 on the spiral plate body 31; Spiral plate body 31 is to adopt the integrated through injection molding moulding with core pipe 32.The outward flange of spiral plate body 31 is provided with thickness less than the shirt rim 331 of described helical baffles 3.The cross section that through hole 33 on the spiral plate body 31 is axial with respect to vertical described heat exchanger tube 7 be projected as circle, can better pass through heat exchanger tube, and increase contact area, and through hole 33 is centered by core pipe 32 that the circumference permutation distributes.Heat exchanger tube 7 distributions are more clear like this, easily mark.
We can see that the one or both ends of core pipe 32 offer installing hole 321 from Fig. 2, and cover plate 2 can be inserted in the installing hole 321 by bolt 4, and cover plate 2 is fixedlyed connected with core pipe 32 like this, also fixedlys connected with cover plate 2 with regard to whole helical baffles 3.Preferably also has sealing ring in the installing hole 321.The installing hole of the other end of core pipe 32 can with housing 1 in latch peg graft.
