Toward the embodiment for being heat exchanger value.In design of heat exchanger and production process, due to the consideration of safety and the requirement of standard, often
It needs first to complete the welding production of entire cylinder, then carries out the assembling of interior outer member, usual heat exchanger structure as shown in Figure 1, shell
Body includes at least three parts by being welded and fixed.
Conventional heat exchanger can have following several problems in process of production：1. for high function, high performance heat exchange
Device often has more complicated internal structure, is influenced by barrel lenght, inner barrel be difficult to complete the assemblings of parts with
Welding, and weldquality is also difficult to ensure；2. for pursuing the heat exchanger of high production capacity, often there is the cylinder of big build, be full
The Requirements of Nondestructive Testing of sufficient cylinder butt weld（According to the requirement of solid content regulation, cylinder butt weld needs specific ray detection factory
Room carries out non-destructive testing, and other types weld seam does not need）, it is necessary to next step work could be carried out by completing the making of entire cylinder first
Sequence；And the manufacture of heat exchanger is a multipaths, the process of multi-line section, and a part of enterprise is caused to be difficult to match enough lifes
Workshop, hoisting sling are produced, the installations and facilities such as non-destructive testing workshop match this large cylinder.
Currently, the characteristics of due to heat exchanger structure, can also use a kind of structure of heat exchanger segmentation shell（As shown in Figure 2
Using spacer flanger sealing structure heat exchanger structure）, including front-end pipe box component 5, rear end header component 3；The structure is by shell
It is divided into two parts making, including left end shell 1, right end shell 2, centre is connected and fixed by flange 4.Cylinder can effectively be solved
The problem of lifting, detection are assembled with internals.
Using spacer flanger sealing structure heat exchanger structure（The flange part connection structure diagram of Fig. 2 as shown in Figure 3）, meeting
There are following several problems;1. due to shell and medium load-bearing, flange position bears that moment of flexure is big, and gasket is easy stress not
Easily cause the leakage of medium；2. itself for flange, needing to refer to or directly using the vessel flange of standard, cylinder
Diameter is bigger, and flange nominal diameter is bigger, and manufacture difficulty is bigger, and cost is higher;3. due to the characteristic of heat exchanger structure,
It asks entire shell to must assure that certain concentricity, therefore requires cylinder both sides flange bolt hole entirely on the center, so manufacture difficulty
Greatly, technological requirement is high；4. when using flanged joint, due to the characteristic of flange connection, it is necessarily required to reserved certain method
Blue bolts assemblies space, also results in the decline of housing unit concentricity.
Utility model content
The technical problems to be solved in the utility model is：A kind of point is redesigned for the defect of existing heat exchanger structure
Segmentation heat exchanger structure avoids inconvenience and the harsh technical requirements of flanged joint of welding assembly, install convenient simple in structure.
In order to solve the above technical problems, the utility model adopts the following technical solution：
A kind of segmented heat exchanger structure, the heat exchanger include front-end pipe box component, rear end header component and heat exchange
Device shell；It is characterized in that：The heat exchanger shell is made of the docking of at least two parts cylinder；Along cylinder axial direction, docking two
The cylinder of side is integrated by intermediate sandwiched intermediate ring docking, and intermediate ring passes through with the cylinder junction for docking place both sides in cylinder
The ring type composition backing of side setting is connected and fixed with welding manner.
Further, a ring type composition backing is respectively arranged with the cylinder junction for docking place both sides in intermediate ring.
Further, intermediate ring and the cylinder junction axial direction indwelling welding seam distance for docking place both sides, the ring type welding
Backing plate axial length is configured to cover a part of heat exchanger shell, the intermediate ring of a part and entire welding seam distance.
Further, intermediate ring inner diameter is identical as heat exchanger shell inner diameter, and intermediate ring outer diameter, which is more than, to be changed
Hot device housing exterior walls diameter；Ring type composition backing is close to intermediate ring and the setting of heat exchanger shell inner wall.
Further, the intermediate ring is annular, cartridge type or bowl-type forging.
When assembling, Life of Heat Exchanger Shell is divided into two parts or multi-section point makes, is respectively completed the making of single part simultaneously
It is qualified to examine, and is then assembled each one pack system by intermediate ring, to complete the making of entire heat exchanger.
This exemplary construction is simple, easy to operate, and manufacturing cost is low, reduces medium disclosure risk.
The advantages of compared to conventional heat exchanger structure the utility model：
1. new heat exchanger structure is simple, easy to operate, the assembling of shell internals and welding are efficiently accomplished；
