Integral, No. two plate type heat exchangers are connected with the steam (vapor) outlet on separating technology tower by No. two steam connection tubes, so that point
Steam in separating process tower is delivered in No. two plate type heat exchangers by No. two steam connection tubes；Due to producing in separating technology tower
Steam temperature relatively low, highest only has 100 DEG C about, thus this steam can be by polyester after being delivered to No. two plate type heat exchangers
Cpeg is heated to 85～95 DEG C.
In order to separate work when overhauling a plate type heat exchanger and No. two plate type heat exchangers moreover it is possible to be delivered to polyester cpeg
Carry out spray process in skill tower, can also include No. three delivery pipes and No. three ball valves, No. three delivery pipes connect delivery pipes with
No. two delivery pipes, and No. three ball valves are provided with No. three delivery pipes.
Preferably, the heating-up temperature of a plate type heat exchanger is 120～130 DEG C.
Preferably, the heating-up temperature of No. two plate type heat exchangers is 85～95 DEG C.
By using this polyester cpeg heater, it is possible to achieve polyester cpeg changes into the handling process of esterification eg, that is,
Polyester cpeg is passed through polyester cpeg heating devices heat to 120～130 DEG C, then the polyester cpeg after heating is delivered to point
Carry out spray process in separating process tower and change into esterification eg；The esterification obtaining eg is delivered to slurry preparation by conveyance conduit
In be used for preparing slurry.
The operation principle of this polyester cpeg heater is: polyester cpeg be delivered in the presence of cpeg pump No. one board-like
It is heated to 120～130 DEG C in heat exchanger or first passes through No. two plate type heat exchangers and be heated to 85～95 DEG C, then pass through a plate again
It is heated to 120～130 DEG C, the polyester cpeg after heating is transported in separating technology tower and carries out spray process in formula heat exchanger,
So that cpeg is converted into the esterification eg needed for configuration slurry, finally separated process tower is delivered in slurry preparation and is used for joining
Slurrying material；When needing to overhaul a plate type heat exchanger and No. two plate type heat exchangers, only open No. three ball valves, close a ball valve
With No. two ball valves, convey polyester cpeg by No. three delivery pipes and carry out spray process to separating technology tower；When maintenance completes, reappear
Open a ball valve and No. two ball valves, close No. three ball valves.
The following is enter after heating devices heat designed by by the utility model for the polyester cpeg separating technology tower with former
First polyester cpeg is directly entered the Contrast on effect table of separating technology tower:
As can be seen here, after the polyester cpeg heater by being designed using the utility model is heated, polyester cpeg
Change into esterification eg, so that substantial amounts of vapor and lower boiling low polymer in polyester cpeg is evaporated, and polyester
Cpeg changes into esterification eg after carrying out spray process in separating technology tower, using this esterification eg as spinning main material, and
In process of manufacture, technological reaction accessory substance reduces in a large number, and spinning break rate reduces more than 10%.
