Catalyst fines and mesh sheet compacting device and compacting method thereof

Abstract

The invention provides a catalyst fines and mesh sheet compacting device. The catalyst fines and mesh sheet compacting device comprises a machine frame, a mesh sheet material frame, a fines container,a fines separating feed mechanism, and a fines and mesh sheet compacting mechanism. The fines and mesh sheet compacting mechanism is used for carrying out high-temperature compacting on catalyst fines and a metallic coil mesh sheet to form catalyst slices, the fines and mesh sheet compacting mechanism comprises two exothermic rollers used for conveying the metallic coil mesh sheet and compactingthe catalyst fines on the metallic coil mesh sheet, the initial end of the metallic coil mesh sheet on the mesh sheet material frame is located between the two rollers, and an discharge position of afines separating feed mechanism is located above the position between the two rollers. The invention further provides a catalyst fines and mesh sheet compacting method, the catalyst fines is subjectedto high-temperature compacting on a mesh sheet to form the catalyst slices, so that the catalyst fines is firmly attached to a mesh sheet carrier, the problem that the catalyst fines is easy to falloff in an reaction process is solved, and quality and efficiency that the catalyst slices realize generation or synthesis of gas are improved.

Description

technical field [0001] The invention relates to the technical field of catalyst sheet processing machinery, more specifically, to a device for pressing catalyst powder and mesh sheet and a pressing method thereof. Background technique [0002] A catalyst is a substance that can change the chemical reaction rate (increase or decrease) of the reactants in a chemical reaction without changing the chemical balance, and its own quality and chemical properties have not changed before and after the chemical reaction. [0003] At present, in many chemical reaction fields, especially in the field of gas generation or synthesis, it is necessary to use catalysts to speed up the reaction rate. The conventional addition method is to directly add the catalyst in the test tube, but in this method, the contact area between the gas and the catalyst is small. , the catalytic effect is not ideal. [0004] For this reason, a metal or ceramic catalyst carrier has been developed in the industry,...

AI Technical Summary

Problems solved by technology

However, the above-mentioned carrier structure has the following defects: because this method accelerates the reaction rate of the catalyst, the catalyst sheet obtained by coating or infiltrating will have a phenomenon that the catalyst and the carrier are not firmly connected or fused, resulting in the phenomenon that the catalyst falls off. Catalyst chips fail or affect the reaction effect and speed of catalyst chips, greatly affecting the quality and efficiency of gas generation or synthesis through catalyst chips
