NON-STIRRED REACTOR, NON-STIRRED PTA AGING CRYSTALLIZATION DEVICE, AND PROCESS AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/127034
Kind Code:
A1
Abstract:
The present invention relates to a non-stirred reactor and a reaction process thereof, and also relates to a PTA aging crystallization device using the non-stirred reactor and an aging crystallization method thereof. A first inlet, a second inlet, a first outlet, and a second outlet are provided on a housing of the reactor, in which both the first inlet and the second inlet are lateral inlets, respectively arranged at an upper portion and a lower portion of the reactor housing, and the first outlet and the second outlet are respectively arranged at a central outlet and a top outlet of the reactor. The non-stirred reactor relies on steam bubbles and kinetic energy generated from a pressure drop to realize the stirring and suspension of a slurry, thereby reducing the manufacturing and maintenance costs of the reactor and the PTA aging crystallization device.
