Abstract
The utility model discloses a high-efficient evaporator, which comprises a barrel, a baffle plate, a pipe plate and heat exchange pipes, wherein the baffle plate is built in the barrel, and comprises a flexible baffle plate and a rigid baffle plate, the heat exchange pipes are in sealing connection with pipe plate holes in the pipe plate in an interference fit manner, the flexible baffle plate and the rigid baffle plate are connected by permanent joint structures, the outer edge of the flexible baffle plate is in interference fit with the inner wall of the barrel, the inner walls of the pipe plate holes in the pipe plate are provided with annular grooves, further improvement is that the outer edge of the flexible baffle plate protrudes from the rigid baffle plate, the permanent joint structures are copper rivets, and the annular grooves are triangular grooves. The assembly between the baffle plate and the barrel is easier, and short circuit of fluid due to leakage caused by a gap generated between the baffle plate and the inner wall of the barrel is effectively prevented, so that the heat transfer efficiency is obviously improved; connection between the flexible baffle plate and the rigid baffle plate is reliable, the corrosion resistance is good, and the service life is long; connection and sealing between the heat exchange pipes and the pipe plate are high in reliability.
Description
Technical field
The utility model relates to a kind of heat transmission equipment, is specifically related to a kind of evaporimeter.
Background technology
In evaporimeter, be provided with for Directed cooling liquid or add the flow direction of hot fluid and the deflection plate of raising flow velocity.Existing deflection plate is a kind of rigid plate-like parts made from metal, plastics or graphite, be inserted in or extract cylindrical shell in order to install or to overhaul, the two must leave gap, this gap has just become passage cooling or heating fluid leakage formation short circuit, must affect heat transfer effect like this, cause evaporimeter heat exchange efficiency lower; On the other hand, in existing evaporimeter, heat exchanger tube is by the tubesheet holes interference fit on expanded joint and tube sheet, and realization is tightly connected, but in use, the tubesheet holes on heat exchanger tube and tube sheet may occur because of the vibration of evaporimeter loosening, even comes off, impact sealing.
Summary of the invention
The utility model is for the deficiencies in the prior art, proposes a kind of heat exchange efficiency, heat exchanger tube of can significantly improving and is connected with tube sheet and seals reliable high-efficiency evaporator.
The utility model is achieved through the following technical solutions technical goal.
High-efficiency evaporator, comprises cylindrical shell, deflection plate, tube sheet, heat exchanger tube; Described deflection plate is built in cylindrical shell, comprises flexible deflection plate and rigidity deflection plate; Described heat exchanger tube is connected by interference fit seal with the tubesheet holes on tube sheet; Its improvements are: described flexible deflection plate is connected by non-disconnectable syndeton with rigidity deflection plate; Described flexible deflection plate outward flange and cylinder inboard wall interference fit; Tubesheet holes inwall on described tube sheet is provided with ring-shaped groove.
Further improve and be: described flexible deflection plate outward flange is given prominence to rigidity deflection plate.
Further improve and be: described non-disconnectable syndeton is copper rivet.
Further improve and be: described ring-shaped groove is triangular groove.
Further improve and be: described ring-shaped groove is spiral groove.
The utility model compared with prior art, has following good effect:
1, the inwall interference fit of flexible deflection plate outward flange and heat transmission equipment cylindrical shell, flexible deflection plate can be out of shape with cylinder inner surface shape, gapless between so flexible deflection plate outward flange and heat transmission equipment cylinder inboard wall, can prevent from causing fluid short circuit because gap produces to leak, and then significantly improve heat transfer efficiency.
2, flexible deflection plate is connected by non-disconnectable syndeton with rigidity deflection plate, can avoid connecting and becoming flexible in use procedure, even comes off, and affects baffling effect.
3, non-disconnectable syndeton is copper rivet, can effectively prevent from causing because of corrosion the fracture of securing member.
4, the tubesheet holes inwall on tube sheet is provided with ring-shaped groove, and heat exchanger tube expanded joint when tubesheet holes on tube sheet is connected, after heat exchanger tube outer wall is squeezed, embeds in ring-shaped groove, has significantly improved like this reliability and sealing reliability that heat exchanger tube is connected with tube sheet.
5, the ring-shaped groove of the tubesheet holes inwall on tube sheet is triangular groove, can further improve reliability and sealing reliability that heat exchanger tube is connected with tube sheet.
