Abstract
The utility model relates to a regeneration tower reboiler with grid type rod baffles, which comprises a shell, a tube box, a tube plate, a plurality of U-shaped heat exchange tubes and a plurality of baffle devices. The ends of the heat exchange tubes form a heat exchange tube bundle disposed in the shell trough the tube plate, the tube box is connected with the tube plate and the shell sequentially, and the baffle devices are arranged lengthwise along the heat exchange tubes. The regeneration tower reboiler is characterized in that the baffle devices are baffle grids, each baffle grid is formed by a plurality of rod baffles, the rod baffles are disposed in parallel while the ends of the rod baffles are connected with baffle rings, the thickness of each rod baffle is equal to a gap between each two adjacent heat exchange tubes, and the rod baffles on the each two adjacent baffle grids are mutually perpendicular. Compared with the prior art, the regeneration tower reboiler has the advantages that (1) flowing direction of shell side fluid in transverse and cross flow is changed into the longitudinal flow axially along the shell through the baffle grids, the fluid filed distribution is uniform, vibration and wear of the heat exchange tube bundles are eliminated, (2) the rod baffles on each two adjacent baffle grids are mutually perpendicular so that turbulent flow is generated, heat transfer is enhanced, and dirt is not easy to deposit.
Description
Technical field
The utility model relates to benzene hydrogenation process for refining regenerator reboiler field, coke-oven plant, particularly a kind of grid formula rod baffle regenerator reboiler.
Background technology
The regenerator reboiler is a kind of kettle type reboiler with media such as heat-conducting oil heating sulfolane, water, micro-hydrocarbon, its employing deflection plate or support plate are as the supporting construction of heat-exchanging tube bundle, prevent the fluid short circuit simultaneously, increase flow velocity, and force fluid path in accordance with regulations repeatedly cross-flow improve the coefficient of heat transfer of shell side by heat-exchanging tube bundle.Because shell-side fluid needs the repeatedly horizontal heat-exchanging tube bundle that skims over, change repeatedly and wash away direction, and the angle of washing away roughly is vertical direction, so the flow resistance of fluid is very big, there is flow dead, and causes induced vibration easily in the part.For reboiler, because the gasification of shell side medium, volume sharply increases, and the condensation of tube side medium, volume sharply reduces, and vibrates, and causes the heat exchanger tube vibration abrasion, finally causes heat exchanger tube to be revealed, and causes production accident.
Summary of the invention
The purpose of this utility model provides a kind of grid formula rod baffle regenerator reboiler, overcomes the deficiencies in the prior art, and reinforcement is fixing to regenerator reboiler heat exchanger tube, eliminates the vibration problem of heat exchanger tube.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of grid formula rod baffle regenerator reboiler, comprise housing, bobbin carriage, tube sheet, heat exchanger tube, baffle means, many U type heat exchanger tube ends are formed heat-exchanging tube bundle by tube sheet and are placed in the housing, bobbin carriage is connected with housing with tube sheet successively, be provided with many group baffle means along the heat exchanger tube length direction, it is characterized in that, described baffle means is a deflecting fence, deflecting fence is connected to form by the many parallel distributions of rod baffle and end and baffling circle, described rod baffle thickness is identical with the gap between the adjacent heat exchange tubes, and the rod baffle on the deflecting fence of adjacent setting is vertical mutually.
Described rod baffle cross section is circle, rectangle or rhombus.
Compared with prior art, the beneficial effects of the utility model are: 1) deflecting fence make originally the shell-side fluid flow direction based on cross-current and cross-flow become along housing shaft to longitudinal stream, Flow Field Distribution is even, the dead band of almost not conducting heat, effectively reduced the shear stress between heat-exchanging tube bundle and rod baffle, eliminate the flow-induced vibration, reduced the wearing and tearing of heat-exchanging tube bundle; 2) owing to the rod baffle on the adjacent deflecting fence vertically is provided with, when the fluid in the shell side flows along tube bank, run into deflecting fence and will produce flow-disturbing, after the intensity of flow-disturbing weakens, can run into next deflecting fence again, produce flow-disturbing once more, so repeatedly the disturbance attenuate laminar boundary layer, strengthened heat-transfer effect effectively, simultaneously because the self-cleaning action of flow-disturbing also makes dirt be difficult for deposition; 3) this heat exchanger has advantages such as long service life, energy savings.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 (a)～Fig. 2 (d) is the one group of deflecting fence structural representation that is provided with in order.
Among the figure: 1-bobbin carriage 2-tube sheet 3-heat exchanger tube 4-deflecting fence 5-housing 6-baffling circle 7-rod baffle
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, it is a kind of grid formula of the utility model rod baffle regenerator reboiler structural representation, comprise housing 5, bobbin carriage 1, tube sheet 2, heat exchanger tube 3, deflecting fence 4, many U type heat exchanger tube 3 ends are fixed in and are formed heat-exchanging tube bundle on the tube sheet 2 and place housing 5 lower inner part, bobbin carriage 1 is connected by bolt with flange on the housing 5 with tube sheet 2 successively, is provided with many group deflecting fences 4 along heat exchanger tube 3 length directions.
See Fig. 2 (a)～Fig. 2 (d), it is the one group of deflecting fence structural representation that is provided with in order, deflecting fence 4 every quadruplets are one group, deflecting fence 4 comprises that 7 parallel distributions of many rod baffle and end are connected with baffling circle 6, rod baffle 7 thickness are identical with the gap between the adjacent heat exchange tubes 3, and the rod baffle 7 on the adjacent deflecting fence 4 is vertical mutually.The cross section of rod baffle 7 can be selected circle, rectangle or rhombus as the case may be.This deflecting fence 4 both had been applicable to square stringing, also was applicable to the triangle stringing, by rod baffle 7 alternately is arranged between every row's heat exchanger tube 3, thereby guaranteed the supporting role of deflecting fence 4 exchange heat pipes 3.
Among the embodiment, heat exchanger 3 adopts square stringing, rod baffle 7 in the first cover deflecting fence is according to horizontally disposed shown in Fig. 2 (a), then second rod baffle 7 of overlapping deflecting fence that is provided with along heat exchanger tube 3 length directions one segment distance is arranged vertically according to Fig. 2 (b), the 3rd cover afterwards is according to horizontally disposed again shown in Fig. 2 (c), rod baffle 7 in the quadruplet is arranged vertically by Fig. 2 (d) again then, length situation according to the regenerator reboiler, specifically determine arrange how much organize such deflecting fence, as long as guarantee the direction of adjacent rod baffle and the interlaced arrangement of position, concrete order mutually without limits.
