Abstract
A strengthening oxidation system of the external micro-interfacial unit for producing PTA with PX is provided, including: a reactor, a circulating heat exchange device and a micro-interfacial unit. The reactor includes an outer casing and an inner cylinder disposed concentrically inside the outer casing. The circulating heat exchange device is disposed at an exterior of the reactor, and is connected with the outer casing and the inner cylinder respectively, for regulating reaction temperatures of the first reaction zone, the second reaction zone and the third reaction zone inside the reactor in a reaction process of producing PTA with PX. the micro-interfacial unit is connected between the reactor and the circulating heat exchange device, and connected with an external feed pipe of the reactor, for crushing a gas phase material into micro bubbles with a diameter greater than or equal to 1 μm and less than 1 mm and for mixing the micro bubbles with a liquid phase material to form an emulsion at the exterior of the reactor before a reaction material enters each of the reaction zones inside the reactor.
