Description
Technical field
The utility model is related to for fused mass directly spinning equipment technical field, especially a kind of esterification waste heat recovery heating rectifying
Device.
Background technology
At present in fused mass directly spinning production, the water byproduct in esterification, excessive EG and a small amount of carboxylate are by ester
Change the top discharge of kettle 1222-R01, initially enter the knockout tower 1223-T01 at the top of reactor and separated,
In knockout tower, substantial amounts of vapor（Temperature is 108.6 DEG C）Distillated from tower top with low boiling organic compound, by air cooler
It is collected into return tank 1223-T03 after 1223-H03 or plate type heat exchanger 1223-H04 coolings, vapor is in cooling procedure
Need substantial amounts of heat energy and electric energy；Moisture is high in CPEG, and temperature is low, is being sent to the distillation process of process tower separation EG and water
In be also required to a large amount of heat energy.
Utility model content
The purpose of this utility model is to solve the deficiency of above-mentioned technology and providing a kind of can make full use of vapor
Heat energy, reduces the esterification waste heat recovery heating rectifier unit of air cooler power consumption.
In order to achieve the above object, a kind of esterification waste heat recovery heating rectifier unit designed by the utility model, it is wrapped
Include process tower, air cooler, backflow collecting tank, recirculation water delivery pump, CPEG tanks and CPEG delivery pumps, also including a heat exchanger and
No. two heat exchangers, the output channel at the top of process tower is connected with air cooler, heat exchanger, No. two heat exchangers respectively, and No. one is changed
Condensed water outlet pipe on hot device, No. two heat exchangers is connected to backflow collecting tank, and backflow collecting tank is connected by recirculation water delivery pump
To process tower, CPEG tanks are connected in parallel a heat exchanger, No. two heat exchangers and process tower, CPEG delivery pumps by CPEG delivery pumps
It is delivered to after the pipeline of CPEG outputs on No. two pipelines and a heat exchanger of heat exchanger converges and is input into No. two heat exchangers；CPEG is defeated
Send pump to be delivered to after the pipeline of CPEG outputs on the pipeline of process tower and No. two heat exchangers converges and be input into process tower.
A described heat exchanger and No. two heat exchangers is plate type heat exchanger.
Above-mentioned technical proposal, the high-temperature vapor that will be exported from process tower is by a heat exchanger and No. two heat exchangers pair
CPEG is heated, and the heat energy so as to cause vapor to produce is fully used, and energy ezpenditure is reduced, while also reducing
The input amount that air cooler and cold plate are changed, further reduces power consumption.In addition when in a heat exchanger or No. two heat exchangers
During one failure, CPEG can be directly switch into another heat exchanger, to ensure that equipment can normally be run, keep work shape
State, improves operating efficiency, and the continuation for using equipment is more preferable.And when simultaneously a heat exchanger, No. two heat exchangers break down
When, CPEG can be fed directly to process tower, although reduce the utilization of vapor heat, but can be that guarantee equipment is normally transported
OK, continuation is more preferably.
Used as optimization, cladding sets adiabator layer on the pipeline between all parts, and the structure can avoid part
Heat is distributed on pipeline, causes the loss and waste of energy.
A kind of esterification waste heat recovery heating rectifier unit obtained by the utility model, the high temperature produced using esterification
Vapor is heated to CPEG, the electric energy consumed for lowering the temperature to high-temperature vapor can have both been reduced, while can also subtract
Few electric energy consumed to CPEG heating, is greatly saved energy cost.
