Abstract
The utility model discloses a spiral baffle plate heat exchanger in the field of thermotechnical devices. The spiral baffle plate heat exchanger comprises a cylindrical housing, wherein a medium inlet is formed in the surface of one end of the cylindrical housing, and a medium outlet is formed in the surface of the other end; end plates are hermetically connected to the two ends of the cylindrical housing respectively; channel boxes are arranged on the outer sides of the end plates respectively; a plurality of heat exchange pipes are arranged in parallel between the end plates at the two ends; a baffle plate is spirally arranged between the end plates; the periphery of the baffle plate is in contact with the inner wall of the cylindrical housing; the center of the baffle plate is positioned on a central supporting rod; and the heat exchange pipes are arranged in a manner of penetrating the baffle plate. When the spiral baffle plate heat exchanger is in operation, a medium to be cooled enters the housing from the medium inlet, flows spirally in the baffle plate which is spirally arranged, and then leaves the device from the medium outlet; during the process, the medium carries out full heat exchange with cooling water in the heat exchange pipes; and when the medium spirally flows, no flowing dead zones exists, so that the cooling medium in the heat exchange pipes performs good heat exchange with the medium to be cooled outside the heat exchange pipes, so as to improve the heat exchange efficiency of the heat exchange pipes.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly a kind of shell-and-tube exchanger.
Background technology
In the prior art, a kind of shell-and-tube heat exchanger is arranged, its structure mainly comprises barrel-type casing, one end side surface of barrel-type casing is provided with the medium import, and other end side is provided with media outlet, and the two ends of barrel-type casing are sealedly connected with respectively end plate, the end plate outside is provided with bobbin carriage, parallelly between the end plate at two ends be provided with some heat exchanger tubes, be interval with some roads deflection plate between the described end plate, the interlaced setting of described deflection plate.In the heat exchanger of this structure, the outer part of heat exchanger tube is called " shell side ", and the part in the heat exchanger tube is called " tube side ", and generally speaking, cooling water can be walked tube side, needs medium such as F12, the F22 etc. of cooling to walk shell side, can certainly exchange.When the medium that need cool off was walked shell side, it entered in the housing from the medium import, after deflection plate repeatedly makes a circulation to flow, again from the media outlet separating device; In this process, the cooling water in medium and the heat exchanger tube carries out sufficient heat exchange.Its weak point is: in the heat exchanger of this structure, when the medium that need cool off flows through from the deflection plate end, the root that is connected with housing at deflection plate can form a fluid dead band, and cooling water and need between the medium of cooling heat exchange few in this zone causes the heat exchange efficiency of heat exchanger low.In addition, the horizontal heat-exchanging tube bundle of plunderring of the fluid of high flow rate can be induced the vibration of heat exchanger tube, has shortened the life-span of heat exchanger.
The utility model content
The purpose of this utility model provides a kind of spiral baffle heat exchanger, heat exchange efficiency that can the Effective Raise heat exchanger.
The purpose of this utility model is achieved in that a kind of spiral baffle heat exchanger, comprise barrel-type casing, one end side surface of barrel-type casing is provided with the medium import, other end side is provided with media outlet, the two ends of barrel-type casing are sealedly connected with respectively end plate, the end plate outside is provided with bobbin carriage, parallelly between the end plate at two ends is provided with some heat exchanger tubes; Be provided with twist deflection plate between the described end plate, described deflection plate periphery contacts with the inwall of barrel-type casing, and the deflection plate center is arranged on the centre post, and described heat exchanger tube passes the deflection plate setting.
During the utility model work, need the medium of cooling to walk from the medium import to enter in the housing, through the deflection plate helical flow of spirality setting, again from the media outlet separating device; In this process, the cooling water in medium and the heat exchanger tube carries out sufficient heat exchange.Because during the medium helical flow, effectively reduced the flow resistance of shell side, flow dead in traditional baffle heat exchanger can not appear, so that heat exchange is good between the cooling medium in the heat exchanger tube and the need cooling medium outside the heat exchanger tube, and because the whirlpool that eddy flow produces and tube bank heat transfer interface boundary layer interaction, turbulivity is increased considerably, greatly improve the film heat transfer coefficient of shell side; Simultaneously, alleviated the vibration of heat exchanger.Compared with prior art, the beneficial effects of the utility model are that this device can reduce the convection current dead band, improve the heat exchange efficiency of heat exchanger tube.
For guaranteeing that helical baffles can stably be installed in the barrel-type casing, described deflection plate periphery is provided with at least one perimeter support bar.The perimeter support bar plays a supportive role, and the edge of deflection plate is not yielding when guaranteeing to install.
As further improvement of the utility model, described heat exchanger tube is interior ripple, male-pipe.Adopt inner corrugated pipe, male-pipe to increase heat exchange area from both sides inside and outside the heat exchanger tube, further improve heat exchange efficiency.
For making things convenient for medium turnover and putting residually, described medium import and media outlet are arranged on the barrel-type casing upside of horizontal setting; The downside of barrel-type casing is provided with puts residual pipe.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the heat exchange tube structure schematic diagram.
Wherein, 1 medium import, 2 barrel-type casings, 3 perimeter support bars, 4 heat exchanger tubes, 5 deflection plates, 6 centre posts, 7 media outlets, 8 end plates, 9 bobbin carriages, 10 put residual pipe.
The specific embodiment
As shown in Figure 1, 2, be a kind of spiral baffle heat exchanger, comprise barrel-type casing 2, this barrel-type casing 2 is horizontal setting, and certainly, it is not limited only to horizontal setting, also can vertically arrange; One end upper side of barrel-type casing 2 is provided with medium import 1, other end upper side is provided with media outlet 7, the downside of barrel-type casing 2 is provided with puts residual pipe 10, the two ends of barrel-type casing 2 are sealedly connected with respectively end plate 8, end plate 8 outsides are provided with on the bobbin carriage 9 of bobbin carriage 9, one ends and are provided with cooling water inlet, are provided with coolant outlet on the bobbin carriage 9 of the other end, parallel some heat exchanger tubes 4, the space in the heat exchanger tube 4 both ends opens connection bobbin carriage 9 of being provided with between the end plate 8 at two ends; Be provided with twist deflection plate 5 between the end plate 8, deflection plate 5 peripheries contact with the inwall of barrel-type casing 2, and deflection plate 5 peripheries are symmetrically arranged with two perimeter support bars 3, and the perimeter support bar also can be evenly equipped with many at deflection plate 5 peripheries; Deflection plate 5 centers are arranged on the centre post 6, and centre post 6 can be pipe, and itself does not participate in the heat exchange of medium, but mainly play a supportive role, simultaneously, walk around the spiral center of deflection plate in the time of can making fluid motion, avoid medium not participate in heat exchange and direct short-circuit; Each heat exchanger tube 4 passes deflection plate 5 and arranges, and this heat exchanger tube 4 is interior ripple, male-pipe.
