Abstract

The invention discloses an impinging stream reactor. The impinging stream reactor comprises a gas-liquid reactor, a communicating pipe and a liquid-liquid reactor from top to bottom, wherein the gas-liquid reactor and the liquid-liquid reactor are connected through the communicating pipe; accelerating pipes, pressure atomizing nozzles and multi-hole gas spray nozzles are arranged in the gas-liquid reactor; a gas outlet is formed in the top of the gas-liquid reactor; the communicating pipe is cylinder-shaped; the centers of the cross sections of the communicating pipe, the gas-liquid reactor and the liquid-liquid reactor are on a same central axis; guide cylinders and an ultrasonic generator are arranged in the liquid-liquid reactor; a feed opening II and a feed opening III are formed in the two side walls of the liquid-liquid reactor, and are communicated with the guide cylinders respectively; a material enters the reactor through the guide cylinders; the guide cylinders are arranged symmetrically on the two sides of the liquid-liquid reactor by adopting the middle of the liquid-liquid reactor as the symmetric line; stirring paddles are arranged in the guide cylinders; the ultrasonic generator is arranged at the bottom of the liquid-liquid reactor; a discharge opening is formed in the bottom of the liquid-liquid reactor. The impinging stream reactor has a wide application prospect in gas-liquid and liquid-liquid reaction, particularly in a preparation process for aluminum oxide dry rubber.

Description

technical field [0001] The invention relates to an impingement flow reactor, in particular to an impingement flow reactor for preparing alumina dry glue. Background technique [0002] At present, pseudo-boehmite is mainly prepared by industrial aluminum hydroxide dissolved in acid and then reprecipitated with ammonia water or other alkalis in China. This method has complex production process, requires anti-corrosion equipment and consumes expensive chemical raw materials. In China, the cost of hydrolysis of organoaluminum compounds produced by other industrial by-products is much lower. In view of the fact that domestically produced pseudo-boehmite cannot compete with foreign countries in price, it is very valuable to research and develop cheap preparation routes and methods. [0003] CN85100161A discloses a kind of " carbonic acid process (CO 2 method) to produce pseudo-boehmite, which uses the intermediate product-industrial sodium aluminate solution as a raw material, ...
