Description
Technical field
The utility model is related to a kind of heat exchangers, more particularly to a kind of tubular sheet heat exchanger and its baffle plate.
Background technology
Tubular sheet heat exchanger includes mainly shell, tube sheet, heat exchanger tube, baffle plate, A liquid inlet, A liquid liquid outlet, B liquid feed liquors
Mouth, B liquid liquid outlet and end socket.Heat exchanger tube is horizontally set in shell, and baffle plate is vertically provided in shell, and tube sheet is vertically arranged
Both ends in shell, end socket are arranged at the both ends of shell, are located on the outside of tube sheet.Shell and tube sheet, tube sheet and end socket it
Between be the connection of close water-stop, be provided with multiple heat exchange pores on tube sheet and baffle plate, heat exchanger tube passes through tube sheet and baffle plate
Heat exchange pore is simultaneously fixed on tube sheet, is connected to the space of shell both ends end socket.In use, A liquid enters end socket from A liquid inlets
It is flowed out via A liquid liquid outlets in heat exchanger tube, B liquid enters the space in shell outside heat exchanger tube around baffle plate stream from B liquid inlets
It is logical to be flowed out via B liquid liquid outlets.Two kinds there are A, B liquid of the temperature difference by the tube wall progress heat exchange that exchanges heat, and realizes high-temp liquid
Cooling and cryogenic liquid heating, to achieve the purpose that quickly to exchange heat.
Baffle plate is extremely important composition component in tubular sheet heat exchanger, is mainly used for supporting heat exchanger tube and changes heat exchanger
The flow direction of shell side side liquid.In order to realize the loss of weight of heat exchanger and increase heat exchange area, usual baffle design all compares
Relatively thin, heat exchanger tube causes to exchange heat directly through the heat exchange pore of baffle plate since shell side side liquid flows washing away for heat pipe of exchange
Gouging abrasion is generated between pipe and baffle plate, the sharp parts exchange heat pipe for the pore that exchanges heat generates dissection, influences heat exchanger tube
Service life, heat exchanger tube leakage may be caused when serious.
In view of there is following technology in the protection of exchange heat pipe：Authorization Notice No. is 204788003 U of CN, entitled " one
The Chinese utility model patent of the baffle plate of kind shell-and-tube heat exchanger " is disclosed wears both ends into horn-like pipe in heat exchange pore
The structure of set, due to the abrasion of heat exchanger tube be by shell side side liquid flow exchange heat pipe wash away cause heat exchanger tube and baffle plate it
Between collision cutting generate, cutting force between the two is reduced with the setting of horn-like pipe sleeve, alleviate and act on heat exchanger tube
Cutting effect（Set up a separatist regime by force of arms effect）, to extend the working life of heat exchanger tube.
But because pipe sleeve is in horn-like, the outside wall surface of heat exchanger tube and the intrados contact portion of pipe sleeve are camber line, therebetween
Contact surface it is still smaller, there are still certain effects of setting up a separatist regime by force of arms, while can be when shell side side liquid is flowed through along baffle plate direction
Flow blind angle is generated between heat exchange pipe outer wall in pipe sleeve, heat exchange efficiency is caused to reduce, therefore designs a kind of folding of practicality and high efficiency
Flowing plate becomes a urgent problem to be solved.
