Abstract
A frame type tubular heat exchanger comprises a shell (1), a tube bundle (2), a tube plate (3), a baffle plate (4) and a water chamber (5). The water chamber is welded outside the tube plate, the tube bundle is fixed on tube holes in the tube plate and the baffle plate, the periphery of the tube plate and the periphery of the baffle plate are welded on a frame (6), the shell wraps the tube bundle, the baffle plate and the frame, and the two ends of the shell are integrally welded with the tube plate. The tube plate can be installed and welded at the two ends of the frame, the baffle plate is arranged in the middle of the frame according to needs, and therefore the tube plate, the baffle plate and the frame are integrated. The frame type tubular heat exchanger is low in weight, reasonable in structure, simple in production process, reliable in quality, and simple to maintain.
Description
Technical field
The utility model relates to a kind of shell-and-tube heat exchanger, particularly a kind of frame-type shell-and-tube heat exchanger.
Background technology
Shell-and-tube (claiming again shell and tube) heat exchanger is a kind of conventional heat exchanger form.As shown in Figure 1, existing shell-and-tube heat exchanger is generally made up of housing 1, tube bank 2, tube sheet 3, deflection plate 4 and hydroecium 5 etc.The connected mode of existing shell-and-tube heat exchanger is generally that housing 1 two ends are welded on the tube sheet 3 of Fixed Tube-sheet Reboiler 2; Support the mobile deflection plate 4 of tube bank and guiding fluid interior according to need of work at housing 1, install and be welded on housing 1; Hydroecium 5 is arranged on tube sheet 3, and guiding fluid flows into tube bank 2.This housing more than 1 rounded (large-scale low-voltage tube shell heat exchanger has ellipse and rectangle), tube bank 2 is generally bundle of parallel tubes or helix tube, and tube bank 2 two ends are fixed on tube sheet 3, and the wall of tube bank 2 is heat-transfer area.In shell-and-tube heat exchanger, carry out two kinds of fluids of heat exchange, a kind of mobile in pipe, its stroke is called tube side; A kind of mobile outside pipe, its stroke is called shell side.
As can be seen from Figure 1, housing 1 is except the container as shell-side fluid, also having a prior function is that tube sheet 3 and deflection plate 4 are installed, the weight of tube bank 2 is all born by housing 1 like this, in order not allow housing 1 because of stressed overweight distortion, the material wall thickness of housing 1 must do strength check in the time of design, and gets certain safety factor, therefore the thickness of general housing is all larger, causes shell-and-tube heat exchanger weight also heavier.
Separately as can be seen from Figure 1, housing 1 is wrapped in deflection plate 4 and tube bank 2, in the process of manufacturing, need on housing 1, open fabrication hole like this, by deflection plate 4 install positioning welding complete after, then closing process hole, causes complex manufacturing like this, weld seam is more.
Summary of the invention
Technical problem to be solved in the utility model is, for prior art deficiency, to provide a kind of convenient for production, thickness of shell attenuate, and safe and reliable frame-type shell-and-tube heat exchanger.
For solving the technical problem of conventional shell-and-tube heat exchanger, the technical scheme that the utility model adopts is: a kind of frame-type shell-and-tube heat exchanger, it comprises housing, tube bank, tube sheet, deflection plate, hydroecium and framework, hydroecium is installed and is welded on tube sheet outside, tube bank is fixed on the pore of tube sheet and deflection plate, and the periphery of tube sheet, deflection plate is installed and is welded on framework, housing parcel tube bank, deflection plate and framework, and housing two ends are welded as a whole with tube sheet installation.
Further being improved to of such scheme, tube sheet is installed the two ends that are welded on framework, and deflection plate is arranged on the centre of framework as required, makes tube sheet, deflection plate and framework become as a whole.
The utility model tube bank, tube sheet, deflection plate are not directly installed on housing, and be mounted on framework, housing only plays container function, no longer play a supporting role, no longer bear the weight of tube bank, tube sheet, deflection plate, thereby the weight of shell-and-tube heat exchanger critical piece is born to have changed into by framework by original housing and bear, housing only plays the container effect of fluid, just attenuate significantly of the material thickness of housing.In process of manufacture, tube sheet and deflection plate are to install to be positioned on framework, and holder housing again after machining like this can not need to be outputed fabrication hole on housing, facilitates production procedure, reduce workload, improve the cleannes of heat exchanger inside.
Compared with prior art, the beneficial effect that the utility model has is:
1, the material thickness attenuate of housing, can alleviate the weight of heat exchanger greatly.
2, production technology is more simple, rationally, facilitates internal soundness inspection.The mode of production was that parts are installed on housing in the past, and housing has determined the size in production operation space, narrow space often, and operating difficulties, is the open type mode of production now, last procedure is holder housing, easy to operate.
3, safeguard that simply the main parts size of heat exchanger was arranged on housing in the past, need to cut some part of housing when inner maintenance open, housing bears weight, and the incorrect meeting of cutting position causes heat exchanger distortion, even scraps; Housing no longer bears weight now, and the heat exchanger that all can not cause Anywhere of cutting housing is out of shape.
Accompanying drawing explanation
Fig. 1 is existing shell-and-tube heat exchanger structural representation.
Fig. 2 is the utility model frame-type shell-and-tube heat exchanger structural representation.
The specific embodiment
As shown in Figure 2, the utility model frame-type shell-and-tube heat exchanger comprises housing 1, tube bank 2, tube sheet 3, deflection plate 4, hydroecium 5 and framework 6, wherein, tube sheet 3, deflection plate 4 are installed and are welded on framework 6, hydroecium 5 is installed and is welded on tube sheet 3, tube bank 2 is fixed on tube sheet 1 and deflection plate 4, and respectively with two, 1 two ends of housing tube sheet 3 is welded in one.When production, first open type is installed tube sheet 3, framework 6, deflection plate 4, tube bank 2, and tube sheet 3 is installed the two ends that are welded on framework 6, and deflection plate 4 is arranged on the centre of framework 6 as required, make tube sheet 3, deflection plate 4 as a whole with 6 one-tenth of frameworks, last procedure is only installs welded case 1.
