Rotary reaction device for hydro-thermal synthesis

Abstract

The invention discloses a rotary reaction device for a hydro-thermal synthesis molecular sieve, which comprises a control system arranged on a seat frame, an electric heating blower and a side horizontal reaction kettle arranged in the electric heating blower, wherein a support rotating mechanism is arranged under the side horizontal reaction kettle and comprises a drive mechanism and two rotating shafts parallel to the center line of the side horizontal reaction kettle, the two rotating shafts are positioned in the electric heating blower, two pairs of transmission idler wheels are arranged on the two rotating shafts, the side horizontal reaction kettle is supported on the two pairs of transmission idler wheels, and the two pairs of transmission idler wheels drive the side horizontal reaction kettle to rotate. The volume of the reaction kettle can be made into the scale of the library pilot scale test, the single-kettle output can reach the kilogram level, and the rotary reaction device is suitable for the optimization of the hydro-thermal synthesis condition in a reaction kettle amplification process and the research of a molecular size subsequent forming process. The stirring form of the reaction kettle is suitable for the growth of the molecular sieve.

Description

technical field [0001] The invention belongs to the field of chemical equipment and relates to a rotary reaction device for hydrothermally synthesizing molecular sieves. Background technique [0002] Molecular sieves are a class of crystalline silicates, aluminosilicates or silicoaluminophosphates, and modified silicates, aluminosilicates or Silicoaluminophosphate. Because of its unique molecular size pore and cavity system, it has the characteristics of sieving molecules and is widely used in metallurgy, chemical industry, electronics, petrochemical, natural gas and other industries. Molecular sieves include natural molecular sieves and synthetic molecular sieves. Natural molecular sieves, namely zeolites, are mostly formed by the reaction of volcanic tuff and tuffaceous sedimentary rocks in marine or lacustrine environments. More than 1,000 kinds of zeolite minerals have been found so far, and the common ones are clinoptilolite, mordenite, erionite and chabazite. Since...

Problems solved by technology

However, these types of reactors are relatively complex in structure, and there are a series of problems such as poor stirring effect and high maintenance cost.

At the same time, these types of reactors can only be used on a small scale, and the quality of molecular sieve products produced in a single batch is limited to the gram level, which is difficult to meet the needs of industrial research such as subsequent molecular sieve product molding.
