Description

The shell-and-tube heat exchanger and the installation method thereof of band parallel split-flow baffles
(1) technical field:
The present invention is the shell-and-tube heat exchanger and the installation method thereof of band parallel split-flow baffles, belongs to heat transmission equipment, particularly utilizes the heat transmission equipment technology of parallel split-flow baffles.
(2) background technology:
Shell-and-tube heat exchanger has multiple structure, especially aspect shell side structure, mainly contain single bow baffling dividing plate, bouble-bow baffling dividing plate, dish ring baffling dividing plate, screen and cavity ring web plate etc. are as the shell side structure of support between pipe, is the main shell side structure form of present industrial heat exchange device with the baffling dividing plate as support between pipe, fluid comes and goes baffling and washes away tube bank between the baffling dividing plate, what the major defect of this heat exchanger structure was the baffling dividing plate all exists the flow starts back dead band with lee face down with the wind, the eddy current yardstick is bigger, the body resistance is higher, and the velocity flow profile in flow field is very inhomogeneous, the effective rate of utilization of heating surface bank is low, heat transfer property is poor, the shortcoming of especially single bow baffling dividing plate is more outstanding, (for example name is called: the Chinese patent of " support between the shell-and-tube heat exchanger pipe " with the cavity ring web plate, the patent No.: 89218385.3) and screen (for example the name be called: the Chinese patent of " convergent-divergent tube, full counterflow bivalve journey axial flow-type heat exchanger ", the patent No.: 012157880) heat exchanger as support between pipe is called the shell side axial flow-type heat exchanger, fluid is restrained at the shell side parallel baffled, the velocity flow profile of axial flow is even, there is not flow blind angle, be that a kind of resistance is little, the heat exchanger that heat transfer efficiency is high, but this heat exchanger only is applicable to the occasion that the logistics volume flow is big, when the logistics volume flow hour then needs bigger housing major diameter Bizet can improve the shell side flow velocity, and too big housing draw ratio is subjected to the restriction of fabricating yard in industry, general being difficult to implemented, thus a lot of heat exchange occasions of liquid or gases at high pressure still need adopt the baffling dividing plate as pipe between the heat exchanger of support.
(3) summary of the invention:
Purpose of the present invention is exactly in order to solve and to overcome the fluid flow starts back dead band of support shell side structure heat exchanger between existing baffling dividing plate pipe big, body resistance height, the flow field velocity skewness, heat transfer property is poor, the heat exchanger that reaches support shell side structure between cavity ring web plate and screen pipe is difficult to be adapted to the problem and the shortcoming of less logistics volume flow heat transfer occasion, research and design is a kind of can effectively control fluid backflow dead band size, reduce the body resistance, the homogenizing flow field velocity, improve heat transfer property, can be adapted to the shell-and-tube heat exchanger of band parallel split-flow baffles of less logistics volume flow heat transfer occasion and the installation method of parallel split-flow baffles thereof simultaneously again.
The present invention realizes by following structure technology scheme and method and technology scheme: structure technology scheme of the present invention is as follows: the structural representation of the shell-and-tube heat exchanger of this band (single bow baffling dividing plate interpolation band arcuate indentation) parallel split-flow demarcation strip as shown in Figure 1, its A-A cutaway view is as shown in Figure 2.It is by heat exchanger shell 1, baffling dividing plate 2, heating surface bank 3, parallel split-flow baffles 4, tube sheet 5, end socket 6, tube side outlet 7, shell side inlet tube 8, shell side outlet 9, tube side inlet tube 10 common installations connect and compose, its mutual alignment and annexation are: heating surface bank 3 is connected back with two ends tube sheet 5 by welding or expand tube and places in the housing 1, heating surface bank 3 constitutes multiply parallel fluid channels between the baffling dividing plate by 2 parallel insertion parallel split-flow baffles 4 of adjacent two baffling dividing plates in housing, two ends end socket 6 and two ends tube sheet 5 are by welding or flange seal is connected and import and export pipe 7 with tube side respectively, 10 by the logical tube side runner that constitutes that is weldingly connected, shell side is imported and exported pipe 8,9 is logical by being weldingly connected with housing 1, and the baffling dividing plate 2 that repeats to settle constitutes shell side runner between the pipe that comes and goes baffling; Wherein: the notch geometry structure of above-mentioned parallel split-flow baffles 4 is arcuate indentation (joining arc baffling dividing plate shown in Fig. 1~2) or circumferential notch (joining dish ring baffling dividing plate shown in Fig. 5~6), or opens earial drainage eyelet (shown in Fig. 3~4) on the pore that enlarges and annular space between heat-transfer pipe and the dividing plate.
Described notch geometry is that the parallel split-flow baffles 4 of arcuate indentation is to be used to have the round circle that lacks the shape baffle heat exchanger lack, and with scarce parallel in the circle of baffling dividing plate 2, diameter is identical, and the plate face is parallel to each other; Described notch geometry is the annulus that are used to have circle-ring baffle plate heat exchanger for circular parallel shunt dividing plate 4, and consistent with the axle center of baffling dividing plate 2, external diameter is between annular baffling dividing plate 2 external diameters and circular baffling dividing plate 2 diameters, and the plate face is parallel to each other; Described notch geometry is to be used to have the circle that circle lacks the shape baffle heat exchanger lack for the parallel shunt dividing plate 4 of the annular space between the pore that enlarges and heat-transfer pipe, has enlarged diameter at pore near shell wall one side, and has annular space between heat-transfer pipe, lack parallel with the circle of baffling dividing plate 2, diameter is identical, and the plate face is parallel to each other.
The installation method of parallel split-flow baffles of the present invention is with between two blocks of adjacent baffling dividing plate pipes of the parallel insertion of one or more parallel split-flow baffles between the support, makes the sub-thread runner between two baffling dividing plates be divided into the multiply parallel fluid channels.
Its operation principles of the shell-and-tube heat exchanger of this band parallel split-flow baffles is: shell-side fluid enters 3 of tube banks by shell side inlet 8, polylith baffling dividing plate between edge and heat-transfer pipe is made to come and go between pipe baffling and is flowed, the parallel fluid channels of separating by parallel split-flow baffles 4 between two adjacent baffling dividing plates divides the multiply parallel fluid to flow, flow out housing by shell side outlet 9 at last, tube side fluid enters the tube side runner by tube side inlet tube 10, flows out tube side via end socket 6 and tube side outlet 7 again after heating surface bank 3.
The present invention compared with prior art has following advantage and effect: 1. parallel insertion parallel split-flow baffles between two adjacent baffling dividing plates, change former single channel into the multiply parallel channels, with former sub-thread flow point is the multiply concurrent flow, can effectively control former sub-thread stream reaches lee face backflow dead band down with the wind at the baffling dividing plate eddy current yardstick, reduce shell side body drag losses, save fluid and carry merit; 2. under the uniform condition of multiply concurrent flow assignment of traffic, the uneven phenomenon of former sub-thread stream velocity flow profile is improved, and flow field velocity between the homogenizing pipe reduces bad heat transfer zone, the heat transfer area of heating surface bank is fully utilized, improves the heat transfer efficiency of heat exchanger; 3. this kind high-performance heat exchanger is difficult to adapt to the little heat transfer operations problem of volume of material flow applicable to the less heat exchange occasion of volume of material flow to solve the shell side axial flow-type heat exchanger.
