Description
One, technical field
The utility model belongs to technical field of heat exchange, is specifically related to a kind of segmental baffle board heat exchangers.
Two, background technology
Condensation (evaporation) device is important, the common apparatus in oil plant, chemical plant.The condensation process of condenser is divided into dropwise condensation and film condensation.The heat transfer rate of dropwise condensation than the big 4-8 of film condensation is doubly wanting big 15-20 doubly in some cases.Though the heat-transfer effect of dropwise condensation is fine, unstable in operation, therefore, industrial condensation process great majority belong to the film condensation operating mode.In condensation process, the molecule in the steam is approaching to the liquid film of tube wall by diffusion, and the latent heat that steam discharges passes toward tube wall by liquid film.The research of condensation rule in the condenser, the computational methods that adopt Nu Xieerte to propose usually.On the shell-side structure of condenser, adopt bow type baffle arrangement usually, bow type baffle arrangement can be divided into single arc and bouble-bow shape structure again.The segmental baffle board heat exchangers that uses all is being equidistant placement aspect the baffling spacing at present.Make the condenser under the existing structure can not give full play to its heat-transfer capability, also increased the flow resistance of fluid.When cooling medium flows in condenser, the volume flow rate of fluid is that the carrying out along with condensation process reduces gradually, and equidistant bow type baffle heat exchanger is not just considered the variation of the volume flow rate of fluid, thereby the heat-transfer capability that causes heat exchanger can not get fully playing, increase falls in the condensing pressure of fluid, even causes the structural deterioration of some steam generation.
Three, summary of the invention
The purpose of this utility model provides a kind of non-equidistant segmental baffle board heat exchangers, it can further improve the exchange capability of heat of fluid in condenser, evaporimeter, the pressure that reduces condensation, evaporation process falls, the destruction of avoiding evaporation process to cause heat-transfer equipment is guaranteed the highly effective and safe operation of equipment.
Non-equidistant segmental baffle board heat exchangers is made up of tube sheet, segmental baffle, pull bar, distance sink tube, heat exchanger tube and housing.Tube sheet is positioned at two ends, and pull bar, heat exchanger tube pass deflection plate, and the heat exchanger tube two ends pass from the pore on the tube sheet of both sides, terminal and tube sheet welding.Pull bar one end and a side pipe plate be by being threaded, and uses nut check after having screw thread to pass last piece deflection plate on the other end.Be with distance sink tube on the pull bar, distance sink tube plays fixedly deflection plate between adjacent two bafflings identical with the breach direction are pulled between adjacent two bafflings are pulled.A plurality of deflection plates equidistant placement not between two tube sheets, and be that the flow direction according to shell-side fluid increases (condenser) successively or reduces (evaporimeter) successively.Because baffle(s) spacing does not wait, so the distance sink tube size is also inequality.
The utility model satisfies the needs of condensation (evaporation) device different volumes flow rate by the different spacing of appropriate design deflection plate.Thereby the raising heat-transfer capability reduces flow pressure drop, and the destruction that also can avoid evaporation process to cause heat-transfer equipment is guaranteed the highly effective and safe operation of equipment.The heat-transfer capability that can make the utility model improves more than 10%, and the pressure that reduces the condenser fluid falls more than 10%.Under same process conditions, the manufacturing cost of condenser does not improve.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is non-equidistant segmental baffle board heat exchangers baffling schematic diagram.
Five, the specific embodiment
Non-equidistant segmental baffle board heat exchangers is made up of tube sheet 1, segmental baffle 3, pull bar, distance sink tube 2, heat exchanger tube 4 and housing.The processing and fabricating of segmental baffle 3 is fairly simple, after processing and fabricating is finished and fixed tube sheet 1, pull bar and distance sink tube 2 on special-purpose mold, form skeleton, note deflection plate 3 centerings and be equidistant placement not.On arrangement of baffles, take the closely spaced structure in spacing large outlet place, fluid intake place for condenser, evaporimeter is taked the big structure of the fluid intake place little exit of spacing spacing, adapted to the variation of fluid volume flow rate, make the heat-transfer capability of condenser or evaporimeter obtain fully playing, condenser is by the flow direction of shell-side fluid, and the adjacent segmental baffle(s) spacing increases successively, and spacing is respectively: 200,250,300,350,400,500,600; Evaporimeter is by the flow direction of shell-side fluid, and the adjacent segmental baffle(s) spacing reduces successively, and spacing is respectively: 600,500,400,350,300,250,200.The screw thread of pull bar and nut should be tightened in order to avoid damage heat exchanger tube 4 because of the deflection plate play when packing into or extract tube bank out.Distance sink tube 2 will keep vertical with tube sheet 1, deflection plate 3, and deviation is no more than 2mm, and tube sheet 1 should with the tube bank axis normal.To after the skeleton group is intact, the heat exchanger tube 4 of scale penetrates the tube bank of skeleton composition.Should not beat heat exchanger tube during poling and assemble by force, make heat exchanger tube recessed flat or scuffing occur.The relative position of centering heat exchanger tube and tube sheet and spot welding after poling is finished.Weld tube sheet and heat exchanger tube angle joint and note skip welding by welding procedure specification (WPS), prevent because of concentrating welding to produce the uneven situation of tube plate deformation and two sides.
