Summary of the invention
The object of the present invention is to provide a kind of lamella heat exchanger of withstand voltage, anti-obstruction, to solve technical problems such as sealing factor height, heat transfer efficiency that traditional lamella heat exchanger exists be low.
Withstand voltage, blockage resistant plate-shell type heat exchanger of the present invention comprises: forward and backward bobbin carriage, housing, tube sheet, plate bundle, expansion joint, sliding support and hold-down support; Adopt the mode of welding to form full welded type plate bundle between corrugated cardboard sheet and the corrugated cardboard sheet, welded type plate bundle is installed in the pressure-bearing shell that is supported by sliding support and hold-down support, and housing and bobbin carriage are provided with the material turnover mouth of pipe respectively; Plate Shu Yiduan by a flange clamping tube sheet be connected with bobbin carriage, the other end is connected with the tube side material mouth of pipe by expansion joint after having bobbin carriage of one's own, described full welded plate bundle is connected by flexible structure with tube sheet, and described corrugated cardboard sheet is strengthened ripple and area and highly less small-sized flow-disturbing reinforcement ripple composition by area and highly bigger main flow-disturbing.
Described withstand voltage, blockage resistant plate-shell type heat exchanger, the hull shape of splendid attire plate bundle can be circle, ellipse or rectangle.
Described withstand voltage, blockage resistant plate-shell type heat exchanger, described all welded type plate Shu Yiduan is fixed on the tube sheet by the flange clamping by flexibly connecting plate.
Described withstand voltage, blockage resistant plate-shell type heat exchanger, but the rectangular cross section structure that described flexible connecting structure is made up of the flat board or the corrugated blank of the modified difference between baffle bundle and tube sheet constitutes.
The present invention has increased withstand voltage, the anti-plugging performance of heat exchanger again when strengthening two Cheng Jiezhi and conducting heat, be particularly suitable at operating temperature height, pressure height, uses in the big heat-exchange system of viscosity and sealing factor.Design pressure difference of the present invention is more than a times of conventional plate type heat exchanger, and negotiable media particle diameter is greater than 6mm.In addition, the flange clamping tube plate structure of this heat exchanger makes heat exchanger removable, when heat exchanger breaks down, can check and keep in repair.

The specific embodiment
Embodiments of the invention are consulted a kind of lamella heat exchanger structure shown in Figure 1, number among the figure: 1. rear header I, 2. vessel flange, 3. tube sheet, 4. housing, 5. the plate bundle, 6. front header, 7. expansion joint, 8. sliding support, 9. hold-down support, 10. inspection manhole, 11-flexible connecting structure, 12. main flow-disturbings are strengthened ripples, 13. little flow-disturbings are strengthened ripples.Among Fig. 1, the shell side import is positioned at the left side of housing top, and the shell side outlet is positioned at the right side of housing below, and the import of plate journey is positioned at housing right-hand member place, and the outlet of plate journey is positioned at the left side of housing below.The shell side outlet is positioned at the left side of housing top among Fig. 2, and the shell side import is positioned at the right side of housing below, and the outlet of plate journey is positioned at housing right-hand member place, and the import of plate journey is positioned at the left side of housing below.
Lamella heat exchanger comprises: forward and backward bobbin carriage 6,1, housing 4, tube sheet 3, plate bundle 5, expansion joint 7, sliding support 8 and hold-down support 10; Adopt the mode of welding to form full welded type plate bundle 5 between corrugated cardboard sheet and the corrugated cardboard sheet, welded type plate bundle 5 is installed in the pressure-bearing shell 3 that is supported by sliding support 8 and hold-down support 10, and housing 3 is provided with the material turnover mouth of pipe respectively with bobbin carriage.The heat transfer unit of lamella heat exchanger is folded to fall to forming by big wave height, the welding of high rigidity corrugated cardboard sheet.Plate, shell-side fluid are flowed into by plate, shell side entrance sleeve respectively, are flowed out by plate, shell side discharge connection behind plate Shu Huanre.The plate bundle that big wave height (wave height that refers to corrugated plating) plate is formed has guaranteed width of flow path, improved equipment anti-plugging performance, reduced the equipment pressure drop.Because plate convection cell heat transfer intensification effect and have the performance of less sealing factor, thereby improve the heat transfer coefficient of heat exchanger, reduce heat exchanger weight, reduce taking up room of heat exchanger; Also having reduced the flow resistance of medium in addition, reduced fluid-pressure drop, had removable, maintenanceability, is the ideal product that heat transfer element updates in the heat-exchange systems such as present crude oil and residual oil.
