Abstract
The utility model relates to a heat exchange device with block type sector-ring-shaped tube plates. A large-size whole tube plate in a shell-and-tube heat exchanger is disassembled into small-size sector-ring-shaped blocking tube plates, and then the blocked sector-ring-shaped tube plates are spliced into a whole circular tube plate. In the splicing process of the sector-ring-shaped tube plates, free contact is adopted, the blocked tube plates are independent without limitation, and reciprocal influences of the blocked tube plates are accordingly avoided. Each sector-ring-shaped tube plate is provided with an independent sector-ring-shaped semicircle tube which serves as an end enclosure, and tube pass fluid is collected by a receiving tube to be then independently discharged out. Two semi-circle end plates are adopted at the two ends of the end enclosure of each sector-ring-shaped semicircle tube to serve as baffles, it is guaranteed that the end enclosures are sealed, and the heat exchange device accordingly forms an independent heat exchange unit.
Description
Technical field
The utility model relates to a kind of heat-exchanger rig with sectional type fan annular tubesheet.
Background technology
Heat-exchanger rig is equipment the most conventional in process industrial, is widely used in numerous industrial or agricultural such as chemical industry, oil refining, power, atomic energy, food, light industry, pharmacy, machinery department.Shell-and-tube heat exchanger is one of heat-exchanger rig of commonly using the most, and in large scale shell-and-tube heat exchanger, the tube sheet of heat exchanger is due to bearing load more complicated, and designing and calculating and manufacture are all comparatively difficult.In order to ensure that large scale heat exchanger tube sheet has enough rigidity, the wall thickness numerical value value of general tube sheet is larger, so, installs and overhauls all very difficult.In addition, typical shell-and-tube heat exchanger heat exchange area is fixed, operating flexibility can only regulate by flow, in adjust flux, flow velocity also can have greatly changed, and causes heat exchanger efficiency fluctuation larger, therefore, in shell-and-tube heat exchanger field, be a very important problem for the research of heat exchanger tube sheet and operating flexibility.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of sectional type tube sheet technology, thereby problem that the rigidity of avoiding large scale tube sheet is not enough, the heat exchanger that simultaneously can make has larger operating flexibility, avoids in the time of Off-design operation the heat exchanger efficiency the causing large drawback that fluctuates.
the utility model adopts following technical scheme:
The utility model resolves into large-sized overall tube sheet in shell-and-tube heat exchanger the fan annular piecemeal tube sheet of reduced size, then is assembled into overall circular tube sheet by the fan annular tubesheet of piecemeal.Each fan annular tubesheet, in assembled process, adopts contact free, and each piecemeal tube sheet is separate, does not retrain each other, thereby has avoided reciprocation each other.Each piece fan annular tubesheet has independently fans annular semi-circular tube as end socket, and discharges separately after tube side fluid being collected by an adapter.The two ends of fanning annular semi-circular tube end socket adopt respectively two semicircle end plates as baffle plate, ensure the sealing of end socket.
good effect of the present utility model is as follows:
Due to each, to fan annular semi-circular tube end socket separate; therefore each piece fan annular tubesheet and the tube bank that connects just become an independently heat exchange unit; can be by closing down or open portion is fanned annular heat exchange unit and regulate the live load of heat exchanger; improve the operating flexibility of heat exchanger, also can in different fan annular heat exchange units, pass into different fluids and realize the object of a kind of shell-side fluid and multiple tube side fluid heat exchange.
Fan annular tubesheet size is less, therefore manufactures and transport very convenient, owing to not interacting between each fan annular tubesheet, can carry out independent intensity to each tube sheet and calculate.Because the size of each fan annular tubesheet is less, under identical rigidity condition, the size of fan annular tubesheet is less than unitary circular tube sheet, and therefore, fan annular tubesheet has less design thickness, can effectively save raw material.Fan annular tubesheet is not connected with cylindrical shell, can not cause additional load to cylindrical shell, can ensure the general safety of cylindrical shell.
Brief description of the drawings
Accompanying drawing 1 is the utility model structural representation.
In the accompanying drawings, 1 semicircle end plate, 2 heat exchanger tubes, 3 fan annular tubesheets, 4 tube side fluid inlet tubes, the annular semi-circular tube end socket of 5 fan, 6 tubesheet holes.
Detailed description of the invention
As shown in Figure 1, the utility model by two semicircle end plates 1, fan annular semi-circular tube end socket 5, fan annular tubesheet 3, some heat exchanger tubes 2 and a tube side fluid inlet tube 4 and form; On fan annular tubesheet 3, be provided with tubesheet holes 6 to facilitate flowing of fluid, two fan annular edge of fanning annular semi-circular tube end socket 5 are connected with fan annular tubesheet 3, and two other semicircle limit is connected with two semicircle end plates 1 respectively.Tube side fluid inlet tube 4 is arranged on the top of the annular semi-circular tube end socket 5 of fan.Some heat exchanger tubes 2 are positioned at the other end of fan annular tubesheet 3, and are connected with fan annular tubesheet 3.
In accompanying drawing 1, the semicircle end plate 1 of fanning annular semi-circular tube end socket 5 right sides is removed, to facilitate the internal structure of observing the annular semi-circular tube end socket 5 of fan.
When work, tube side fluid is flow to by fan annular tubesheet 3, is fanned annular semi-circular tube end socket 5 and two spaces that semicircle end plate 1 forms by tube side fluid inlet tube 4, then enters via the tubesheet holes 6 being arranged on fan annular tubesheet 3 the tube bank participation heat exchange being made up of heat exchanger tube 2; The shell-side fluid tube bank outer surface that heat exchanger tube 2 forms of flowing through, by tube wall and the tube side fluid heat exchange of heat exchanger tube 2, completes whole heat exchanging process.
