Description
Technical field
This utility model belongs to technical field of heat exchangers, and in particular to a kind of multiple exit shell-and-tube heat exchanger of controllable temperature.
Background technology
Shell-and-tube heat exchanger used in central heating secondary network electric heating pump peak regulation system, goes out according to only one shell side
The conventional structure of mouth, it is as follows with once net water heat exchange existing problems.One is due to restraining heat-transfer surface in conventional shell-and-tube heat exchanger
Product is substantially stationary, constant in the medium temperature and flow of tube side import, and the heat exchange medium temperature and flow of shell side import is not
In the case of change, the heat exchange medium temperature for wanting to control shell-side outlet is relatively difficult.If electric heating pump vaporizer inflow temperature
Too high, medium is easily in high temperature, high pressure conditions in vaporizer, affects very big to the service life of electric heating pump assembly；Two is for steady
Determine the inflow temperature of electric heating pump vaporizer, need the inlet and outlet pipe in electric heating pump vaporizer to concatenate an electric three passes and adjust
Valve, is mixed using the relatively low vaporizer water outlet of temperature with shell side water outlet, the inflow temperature of vaporizer is controlled with this, due to being typically for
The once net of hot heat exchange station and the confession of secondary network, backwater caliber are larger, and concatenation electric three-way regulating valves are easily limited by space is transformed
System.
Utility model content
The purpose of this utility model is to provide a kind of multiple exit shell-and-tube heat exchanger of controllable temperature, overcomes existing shell to exchange heat
What device was present（Shell side）The deficiency that heat exchange medium temperature can not be adjusted voluntarily.
Shell-and-tube heat exchanger of the present utility model includes two panels dividing plate, the welding of tubular closure, inside the shell near two ends
One group of medium circulation tube that shell two ends cavity volume is connected on dividing plate, the medium entrance for being located at shell two ends and outlet, it is located at two
Heat transferring medium inlet and outlet, inside the shell between piece dividing plate on side wall of outer shell be crisscross arranged between two panels dividing plate several pieces lead
Stream plate, the passage between the import and export of shell two ends forms tube side, and the passage on side wall of outer shell between import and export forms shell side, institute
The improvement of work is：Between shell side import and shell side end outlet on side wall of outer shell（Shell side is interval）Increase by one or one with
Upper shell side stage casing outlet, medium delivery pipe for connecting each interval outlet of shell side is collected and is connected to a threeway or is powered dynamic more
On flow control valve.Electric flow control valve configures flow controller；Described flow controller, goes out including shell side end is located at
Temperature sensor in mouth, the outlet of shell side stage casing, electric flow control valve outlet or medium delivery pipe, treatment temperature transducing signal
And the control module of output regulation and control electric flow control valve electric current.
Increase a shell side stage casing outlet between shell side import and shell side end outlet on side wall of outer shell, connect shell side
Stage casing exports to collect with the medium delivery pipe of shell side end outlet and is connected on an electric three-way flow control valve.
A kind of porous shell-and-tube heat exchanger method of operation of controllable temperature of the present invention is as follows：Temperature medium middle first passes through connecting line
Into the tube side water inlet of multiple exit shell-and-tube heat exchanger, middle temperature medium heat is passed to by tube bank outer wall by tube bank inwall reverse
The low-temperature heat exchange medium of flowing, thus the middle temperature medium temperature in tube side be minimized, become cryogenic media, via multiple exit pipe
The tube side outlet of shell heat exchanger flows out.
At the same time, low-temperature heat exchange medium enters the shell side water inlet of multiple exit shell-and-tube heat exchanger by connecting line, leads to
The middle temperature media for heat exchange of tube bank outer wall and tube bank inwall reverse flow is crossed, and under the regulation of electric three-way regulating valves, a part
After low-temperature heat exchange medium is by restraining the less low-temperature heat exchange region heat exchange of heat exchange area, flow out from shell side stage casing outlet, and
One water inlet of electric three-way regulating valves is entered by connecting line；Another part low-temperature heat exchange medium is by restraining heat-transfer surface
After the maximum middle temperature heat exchange area heat exchange of product, flow out from shell side outlet water at tail end mouth, adjusted into electric three passes by connecting line
Another water inlet of valve.Low-temperature heat exchange medium after gentle low-temperature heat exchange region is heated up in, the entrance of lower temperature is electronic
One water inlet of three-way control valve, another water inlet of the entrance electric three-way regulating valves of higher temperature, after two-way heats up
Low-temperature heat exchange medium mixed inside electric three-way regulating valves after, then by electric three-way regulating valves outlet flow out,
Complete the shell side of a multiple exit shell-and-tube heat exchanger and the heat exchange of tube side, and the regulation process to shell side leaving water temperature.
Good effect of the present utility model is
1st, it is to restrain the less low-temperature heat exchange region of heat exchange area, shell side outlet water at tail end mouth that shell side stage casing outlet is corresponding
Corresponding is to restrain the maximum middle temperature heat exchange area of heat exchange area, by electric three-way regulating valves to multiple exit shell-and-tube heat exchanger
The regulation of shell side stage casing outlet and shell side outlet water at tail end mouth flow, can by the heat exchange total amount of shell side and tube side, and electronic three
The outlet temperature of logical regulating valve is controlled on optimal node.
2nd, the stability of the vaporizer inflow temperature of electric heating pump regulating units, is related to the safety fortune of electric heating pump regulating units
OK, after using multiple exit shell-and-tube heat exchanger and the once net backwater indirect heat exchange mode of temp. controllable, by once net return water temperature
Impact of the transient change to secondary network electric heating pump regulating units vaporizer is preferably minimized.
3rd, because electric heating pump regulating units need to be connected on once net on middle temperature water return pipeline, if resistance is excessive influencing whether
Original hydraulic equilibrium once netted, because the resistance ratios plate type heat exchanger of the multiple exit shell-and-tube heat exchanger of controllable temperature it is low by more than 50%, can
Reduce to greatest extent once netting hydraulically balanced impact to original.
