Description

The pipe baffle system and lamella heat exchanger of distribution pipe for lamella heat exchanger

Technical field

The utility model relates to the pipe baffle systems and lamella heat exchanger of the distribution pipe of lamella heat exchanger.Shell-and-plate changes Hot device usually have shell, the heat transfer plate being arranged in shell stacking and extend through heat transfer plate stacking distribution pipe.For By being formed between heat transfer plate every a gap, pipe baffle system is configured to for separating distribution pipe the flow channel of fluid stream Pipe surface in the longitudinally adjacent window fluid inlet and fluid outlet that make them be used separately as fluid stream.

Background technique

Now, various applications are used for there are many different types of lamella heat exchangers and depending on its type.Some classes The lamella heat exchanger of type has the shell for the capsule for forming sealing, and the heat transfer plate of connection is arranged in the capsule of sealing.Heat transfer plate The stacking of heat transfer plate is formed, wherein the staggered first flow path and second flow path for first fluid and second fluid are formed in biography Between hot plate.

(the disclosure of the application is whole with its by quoting for the Chinese invention patent application of Publication No. CN106537079A Body is incorporated herein) disclose the typical case of this lamella heat exchanger, wherein each heat transfer plate include first port opening, Second port opening, the first side and second side opposite with the first side.Heat transfer plate is arranged in shell, and is enduringly attached to that This, so that: i) for first group of flow channel of first fluid by being formed every a gap between heat transfer plate, wherein fluid Entrance and fluid outlet are in first port opening and second port opening and ii) it is used for second group of flowing of second fluid Channel every another gap by forming between heat transfer plate, and wherein fluid inlet and fluid outlet are in the first side and second side Place.Lamella heat exchanger has the first distribution pipe of the first port opening for extending through heat transfer plate, and including by first-class Body block piece and fluid outlet separated from each other and fluid inlet.Second distribution pipe extends through the second port opening of heat transfer plate And including fluid inlet and fluid outlet, the fluid inlet of the second distribution pipe such as passes through to be arranged to and the first distribution seen in heat transfer plate The fluid outlet of pipe is opposite, and the fluid outlet of the second distribution pipe such as passes through the stream being arranged to seen in heat transfer plate with the first distribution pipe Body entrance is opposite.First access extends along the first side of shell and heat transfer plate, and including passing through second fluid block piece and dividing each other The fluid outlet section and fluid inlet section opened, and alternate path extends along second side of shell and heat transfer plate, and including fluid Entrance zone, threshold zone and fluid outlet section, the fluid inlet section of alternate path such as passes through to be arranged to and the first access seen in heat transfer plate Fluid outlet section it is opposite, and the fluid outlet section of alternate path is as passed through and be arranged to the first access seen in heat transfer plate Fluid inlet section is opposite.Since distribution pipe is arranged in the port openings of heat transfer plate, therefore prevent so-called snake, that is, pass Hot plate is moved relative to each other or reverses.This makes lamella heat exchanger more durable and can stand high pressure.

First distribution pipe and the second distribution pipe can extend to bottom cover from the top cover of shell.First fluid resistance in first distribution pipe Block piece may include the disk with periphery, be attached to the inside of the first distribution pipe.Second fluid block piece may include along heat transfer plate Heat transfer plate the first side and along shell inner surface extend periphery.Second fluid block piece can integrally be tied with the heat transfer plate It closes, second fluid block piece extends along heat transfer plate.First distribution pipe may also include second fluid outlet, be located at the first distribution pipe Fluid inlet beside, and the second distribution pipe may include second fluid entrance, such as passes through and is arranged to seen in heat transfer plate and first The second fluid outlet of distribution pipe is opposite, and is separated by third fluid barrier and the fluid outlet of the second distribution pipe.First Access may include the second fluid exit zone beside the first entrance section of the first access, and alternate path may include the Two fluid inlet sections, such as pass through be arranged to seen in heat transfer plate it is opposite with the second fluid exit zone of the first access and logical The 4th fluid barrier and the fluid outlet section of alternate path is crossed to separate.

In the lamella heat exchanger disclosed in CN106537079A above, the first fluid in the first distribution pipe stops Third fluid barrier in part and the second distribution pipe generally has the shape of disk and is respectively welded in the peripheral region of disk The inside of one distribution pipe and the second distribution pipe, so that can flow through first fluid block piece and third fluid barrier without fluid.

However, the fluid barrier of plate-like in the peripheral region of disk is soldered to distribution pipe, there are some disadvantages.On the one hand, it welds The component for needing first to be fixedly welded when connecing block piece, this to be difficult to adjust the position of the component of welding in welding operation, and And when block piece is damaged by fluid erosion, need to replace even entire distribution guard system.On the other hand, the block piece of welding Usually no fluid is made to can flow through block piece in the inside that peripheral region is soldered to distribution pipe completely, this is not able to satisfy in block piece Place needs the application of bypass flow path.

The baffle bar assembly of damper rod, baffle insert and fixture composition is also used in distribution pipe at present, wherein baffle Plug-in unit is retained on the specified location on damper rod by fixture, and baffle bar assembly is then fixed on distribution pipe using tripod End so that baffle insert the appropriate position of distribution pipe be used as fluid barrier.However, since fluid stream is to baffle The constant impingement of plug-in unit, the fixing of the fixture in above-mentioned baffle bar assembly may become less securely, to influence block piece Effect.Further, since the tolerance in distribution pipe, when baffle bar assembly is placed in distribution pipe, baffle plate insert is quasi- Really being fixed on designated position aspect, there may be problems.

Therefore, there is the needs to novel pipe baffle system and lamella heat exchanger, pipe baffle system therein in estimation It is avoided that the above problem, and lamella heat exchanger can stand high pressure level, while being applicable to the needs at block piece The application of bypass flow path.
