Production apparatus for aluminium oxide catalyst carrier

Abstract

A disclosed production apparatus for an aluminium oxide catalyst carrier comprises a kettle body, and the kettle body is provided with a motor, a decelerator, a feed pipe a , a safety valve, a feed pipe b, a stirrer, a discharge port, supporting legs, a heating pipe, a heating interlayer and a heat inlet pipe; and the production apparatus is characterized in that the kettle body is provided with a sampler, the sample is disposed on the kettle body, and a sealing cover is arranged between the sampler and the kettle body; the stirrer in the kettle body is provided with a kettle-bottom stirring paddle, the kettle-bottom stirring paddle is arranged at the lowest end of the stirrer, and a roller is arranged between the kettle-bottom stirring paddle and the kettle bottom. The technological effects comprise that 1, the pH value variation of a solution in the reaction kettle can be rapidly known through the sampler, and periodic swing of pH value can be realized by employing different feeding manners; 2, the stirrer is added with a transverse stirring shaft, the stirring manner is increased, the binding force of solution molecules is enhanced, and the chemical reaction efficiency is improved; and 3, reactants are layered and heavy substances sink because of different specific gravity of various molecules in the solution, but the kettle-bottom stirring paddle helps to reduce the phenomenon; and the reaction kettle is extremely convenient for control on the pore size of the catalyst carrier.

Description

(1) Technical field [0001] The invention relates to a reaction kettle, in particular to an alumina catalyst carrier production device. (two), background technology [0002] The traditional reaction kettle has the defects of single function, uneven stirring, and insufficient heat exchange, especially in the process of producing the catalyst carrier, because the pore size of the catalyst carrier has a direct relationship with the chemical reaction process, so it is required to In addition to being able to control temperature, pressure, and liquid concentration, it is also necessary to control the stirring method, especially to control the pH of the solution to do periodic swings within a certain range. In order to realize the periodic swing of the pH of the solution within a certain range, multiple uninterrupted and accurate sampling is required, and different reaction solutions are periodically added. The general reaction kettle requires manual operation, which is very troubl...

[0002] The traditional reaction kettle has the defects of single function, uneven stirring, and insufficient heat exchange, especially in the process of producing the catalyst carrier, because the pore size of the catalyst carrier has a direct relationship with the chemical reaction process, so it is required to In addition to being able to control temperature, pressure, and liquid concentration, it is also necessary to control the stirring method, especially to control the pH of the solution to do periodic swings within a certain range.

In order to realize the periodic swing of the pH of the solution within a certain range, multiple uninterrupted and accurate sampling is required, and different reaction solutions are periodically added. The general reaction kettle requires manual operation, which is very troublesome, so a catalyst carrier is required. Special reactor, this is our research topic
