Utility model content
The purpose of this utility model is to be directed to drawbacks described above of the prior art, there is provided a kind of collection shell and tube attemperator
The efficient performance of the characteristics of high temperature resistant, high pressure and heat-exchangers of the plate type is in the plate-type heat-exchange with shell and tube attemperator of one
Device, reach energy-conservation, efficient purpose.So as to finish the history that plate type heat exchanger is not suitable with steam medium.
Its main operational principle is by the way that shell and tube attemperator and heat-exchangers of the plate type are connected to become into one by pipeline
It is overall.Heat-exchangers of the plate type belongs to the heat exchange of secondary surface formula.One-level heat exchange adds for high temperature and high pressure steam in shell and tube attemperator
Hot cold medium, meanwhile, steam changes into steam water interface of the temperature less than 150 degrees Celsius by decrease temperature and pressure and enters board-like heat exchange
Device, into heat-exchangers of the plate type after steam water interface continue heat cold medium, belong to secondary heat transfer, utilize heat-exchangers of the plate type
Efficient performance, the heat in steam is taken out to greatest extent, reach the purpose of energy-conservation.
To achieve the above object, the utility model uses following technical scheme：Plate-type heat-exchange with shell and tube attemperator
Device, including plate type heat exchanger, it is characterised in that the plate type heat exchanger is connected by pipeline and flange with shell and tube attemperator,
Cold medium entrance and condensation-water drain are set on the plate type heat exchanger, steam inlet and cold is set on the shell and tube attemperator
Media outlet, cold medium are entered by the pipeline again after being exchanged heat from the cold medium entrance into the plate type heat exchanger
The shell and tube attemperator carries out secondary heat exchange and then exported from the cold medium to discharge, and high temperature and high pressure steam enters from the steam
Mouth enters in the shell and tube attemperator carries out heat exchange until steam changes into temperature through decrease temperature and pressure and taken the photograph less than 150 with cold medium
Enter after the steam water interface of family name's degree the plate type heat exchanger and cold medium further heat exchange up to changing into condensed water from described
Condensation-water drain is discharged.
Further, the area of the shell and tube attemperator can adjust.
Further, the shell and tube attemperator is fixed on above the plate type heat exchanger by support base.
Further, the shell and tube attemperator is fixed on the support base by fixed strip and supporting plate, the branch
The breach to match with shell and tube attemperator shell shape is provided with fagging.
Further, the heat-exchangers of the plate type is fixed on base.
The utility model compares with prior art, and its effect is positive and obvious.The utility model heat transfer coefficient height,
Floor space is small, assembling is flexible, easy to maintenance, and due to belonging to secondary heat exchange, Btu utilization is abundant, saves to greatest extent, energy
Enough fully heat exchange, vapor (steam) temperature pressure adaptation scope is wide, less scaling, and operating cost is low.
