Abstract
The utility model relates to a polyester (PET) condensation polymerization reaction system, which belongs to the technical field of chemical engineering machinery equipment. The PET condensation polymerization reaction system is characterized in that the system comprises a condensation polymerization kettle (1), a primary primary spraying tower I (2), a secondary secondary spraying tower I(3), a glycol collection tank I (4), a pump I (5), an oligmer pipe (6), a final polymerization kettle (7), a primary spraying tower II (8), a secondary spraying tower II (9), a glycol collection tank II (10) and a pump II (11). The PET condensation polymerization reaction system omits a glycol stabilizing tank and directly pumps glycol gas generated after the final polymerization reaction into the condensation polymerization kettle through a pump, so when the product quality is ensured, the flow process of the production process is also simplified, and in addition, a large number of energy sources are saved.
Description
(1) technical field
The utility model relates to a kind of PET polycondensation system, belongs to the chemical mechanical equipment technical field.
(2) background technology
In the PET polycondensation system, need lead to recycling in the polycondensation vessel with gathering the ethylene glycol gas that produces in the reaction eventually.In the common PET polycondensation system ethylene glycol gas is led to earlier in the ethylene glycol stable can, by pump ethylene glycol gas is got in the polycondensation vessel again.Yet so just caused the lengthy and tedious of technology, also caused the aggravation of energy consumption.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of simplification technology, and the PET polycondensation system of save energy.
The purpose of this utility model is achieved in that
A kind of PET polycondensation system is characterized in that: it comprises polycondensation vessel, one-level spray column I, secondary spray column I, oligomerisation property management, terminal polymerization kettle, one-level spray column II and secondary spray column II;
Described polycondensation vessel links to each other with one-level spray column I, described secondary spray column I links to each other with one-level spray column I, described one-level spray column I bottom is provided with ethylene glycol holding tank I, the bottom of described ethylene glycol holding tank I is provided with pump I, the liquid outlet of described pump I links to each other with one-level spray column I, described oligomerisation property management links to each other with polycondensation vessel, described terminal polymerization kettle links to each other with polycondensation vessel, described terminal polymerization kettle links to each other with one-level spray column II, described secondary spray column II links to each other with one-level spray column II, the bottom of described one-level spray column II is provided with ethylene glycol holding tank II, and described ethylene glycol holding tank II bottom is provided with pump II, and the liquid outlet of described pump II links to each other with the oligomerisation property management with one-level spray column II respectively.
The beneficial effect that the utlity model has is:
This PET polycondensation system has removed the ethylene glycol stable can, directly the ethylene glycol gas of poly-reaction back generation is eventually thrown in the polycondensation vessel by pump.So just, when having guaranteed quality product, simplify the technological process of production again, and saved a large amount of energy.
