Description
Technical field
The utility model relates to machinery field more particularly to heat exchange machinery, especially a kind of shell-and-plate heat exchangers.
Background technique
Lamella heat exchanger be by the tube bank in shell-and-tube heat exchanger with plate beam substitute and formed product, by shell,
The main elements such as plate beam are constituted, and form " plate journey " and " shell side " two kinds of fluid channels.Plate beam is the core of lamella heat exchanger,
Middle plate determines the thermal performance of heat exchanger as heat conducting element.What shell mainly determined lamella heat exchanger holds warm pressure-bearing energy
Power and the security reliability of operation operation.In the prior art, there are dividing plates and inner walls to seal for shell-and-plate heat exchanger
Not the problem of tight leakage current, small disk and thin plate process is short, and using multipaths, when temperature high or special chemical medium is nonmetallic close
Envelope cannot be used, and since plate beam is made of many circular plates, assembly technology has certain limitation, when shell side is multipaths
When sealing it is difficult, too big the generations by-pass flow in gap influences heat transfer effect, and gap too small assemble is not easy to realize.
Utility model content
The purpose of this utility model is that in view of the above-mentioned drawbacks in the prior art, providing a kind of novel shell-and-plate heat exchange
Device structure.
Its main operational principle be by being radially fully welded dividing plate along shell to the inner walls, will be in shell
Part is divided into two that seal against each other isolation for the space of the plate beam to be arranged, and two media passes through respectively to be arranged in two skies
Between two plate Shu Jinhang be successively heat exchanged.
To achieve the above object, the utility model uses following technical scheme: shell-and-plate heat exchanger, including shell, close
Envelope is connected to sealing plate, the shell side import being arranged on shell and the shell-side outlet of the shell two sides, the plate being arranged on sealing plate
Journey import and the outlet of plate journey, plate beam and dividing plate that case inside is set, which is characterized in that be arranged on the left side sealing plate
The import of left plate journey and the outlet of left plate journey, the left plate journey import and the outlet of left plate journey are connected in the enclosure interior, the right side
The import of right panel journey and the outlet of right panel journey are set on sealing plate, and the right panel journey import and the outlet of right panel journey connect in the enclosure interior
Logical, the left plate journey outlet is connected in the hull outside by pipeline with the right panel journey import, the top of the shell with
The respectively arranged upper shell side import in lower part, upper shell-side outlet and lower shell side import, lower shell-side outlet, the size of the dividing plate
It is consistent with the enclosure interior radial section with shape, and be radially fully welded along shell to the inner walls, by enclosure interior
Be separated into and seal against each other two of isolation for being arranged the left plate beam cabin and right panel beam cabin of the plate beam, the lower shell side import with
The upper shell-side outlet is connected in right panel beam cabin, and the upper shell side import and the lower shell-side outlet are in the left plate beam
It is connected in cabin, the upper shell side import and upper shell-side outlet are connected in the hull outside by pipeline.
Further, the enclosure interior radial section is circle, and the dividing plate is diameter and the housing inner diameter
Consistent circle.
The utility model compares with prior art, and effect is positive and apparent.The utility model solves shell-side
Nonmetallic sealing obsolete problem when the poorly sealed leakage current of dividing plate, small template process be short and temperature is high or special media,
It can be adapted for any operating condition.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model.
Specific embodiment
Embodiment
As shown in Figure 1, a kind of shell-and-plate heat exchanger, including shell 9, the sealing plate that is sealedly connected on 9 two sides of shell,
The shell side import being arranged on shell 9 and shell-side outlet, the plate journey import being arranged on sealing plate and the outlet of plate journey are arranged in shell
The plate beam and dividing plate 12 of 9 insides, which is characterized in that left plate journey import 1 is set on the left side sealing plate 10 and left plate journey goes out
Mouth 2, the left plate journey import 1 and left plate journey outlet 2 are connected to inside the shell 9, and right panel is arranged on the right side sealing plate 11
Journey import 3 and right panel journey outlet 4, the right panel journey import 3 and right panel journey outlet 4 are connected to inside the shell 9, the left plate
Journey outlet 2 is connected to outside the shell 9 by pipeline with the right panel journey import 3, the upper and lower part difference of the shell 9
Shell side import 7, upper shell-side outlet 6 and lower shell side import 5, lower shell-side outlet 8, the size and shape of the dividing plate 12 in setting
Shape is consistent with the 9 inner radial section of shell, and is fully welded along 9 radial direction of shell to 9 inner wall of shell, inside shell 9
Be separated into and seal against each other two of isolation for being arranged the left plate beam cabin 13 and right panel beam cabin 14 of the plate beam, the lower shell side into
Mouth 5 is connected in right panel beam cabin 14 with the upper shell-side outlet 6, and the upper shell side import 7 exists with the lower shell-side outlet 8
Connection in left plate beam cabin 13, the upper shell side import 7 and upper shell-side outlet 6 are connected to outside the shell 9 by pipeline,
Medium A: enter left plate journey outlet 2 from left plate journey import 1, then come out from left plate journey outlet 2 and enter right panel journey import 3, from right panel
Journey import 3 enters right panel journey outlet 4, then comes out from right panel journey outlet 4；Medium B: go out from lower shell side import 5 into upper shell side
Mouth 6, then come out from upper shell-side outlet 6 and enter upper shell side import 7, upper shell side import 7 enters nozzle 8, then from lower shell-side outlet 8
Out.By being fully welded the dividing plate 12 to 9 inner wall of shell, make that it is equally loaded, under the high temperature and pressure of medium still
It is able to maintain sealing not leakage current, while the left plate beam cabin 13 being separated out and right panel beam cabin 14 effectively solve that small template process is short to ask
Topic.
Further, the enclosure interior radial section is circle, and the dividing plate is diameter and the housing inner diameter
Consistent circle further avoids other shapes when welding and being under pressure there are stress centrostigma, further improves
Leakproofness and durability under high temperature and high pressure environment.
