SCR denitration catalyst intensive mixer mixing powder raw materials in the ceramic industry

SCR denitration catalyst intensive mixer is a kind of equipment used in the production of SCR denitration catalyst to achieve efficient and uniform mixing of materials.The following is a related introduction:

SCR denitration catalyst inclined intensive mixer principle and structure

SCR denitration catalyst inclined intensive mixer structure:rotor transmission mechanism,material tray transmission mechanism,rotating cylinder,discharge door and other structures.

Countercurrent mixing principle:The motor is driven by a belt to the worm gear reducer,and the cylinder is driven to rotate through a set of gears to drive the material mixing movement,and the high-speed rotor is used to make the material mixed evenly.After completing a mixing process,the discharge door located at the lower center of the cylinder drives the discharge through the hydraulic cylinder.

SCR denitration catalyst intensive mixer

CONELE inclined mixing mixer is mainly used for mixing various powder raw materials in the ceramic industry(dry mixing and wet mixing are possible).
It is developed and produced for various different tasks of raw materials,ingredients and blanks.It is mainly used for mixing raw materials in ceramic factories,such as mixing raw materials for SCR honeycomb denitrification catalyst production lines and mixing other powders.
The high efficiency of the intensive mixer is determined by the following four main features:
1.The rotating mixing disk installed at an angle;
2.There is only one continuously rotating mixing device;
3.If there is a special need,the mixing shaft,mixing blade and scraper can be made into a hollow water-cooled form;
4.Adjustable multifunctional scraper device;
5.During operation,a phase-reverse mixed material flow with a very high speed difference is formed;
This can bring the following significant advantages to users:
1.Optimal uniformity of mixed materials;
2.Short mixing time;
3.Less equipment wear;
4.Less maintenance of structural parts;
5.Good and quite stable mixing quality;

6.The operation mode can be intermittent or continuous;

The production process of SCR(selective catalytic reduction)denitrification catalyst is relatively complex,and the production process of catalysts of different types and uses will be slightly different.The following is an introduction to a common production process:

Raw material preparation
Active component raw materials:Common active components include vanadium(V),tungsten(W),molybdenum(Mo),etc.,which generally exist in the form of their salts or oxides,such as ammonium metavanadate,ammonium tungstate,etc.These raw materials need to have high purity to ensure the performance of the catalyst.
Carrier raw materials:The commonly used carrier is titanium dioxide(TiO₂),which has a large specific surface area and good chemical stability.The particle size,crystal form and other parameters of the carrier raw materials have an important influence on the performance of the catalyst.
Auxiliary raw materials:In order to improve the performance of the catalyst,some additives may be added,such as compounds of cerium(Ce)and zirconium(Zr),which can improve the activity,stability and anti-poisoning ability of the catalyst.
Binders:Such as silica sol,aluminum sol,etc.,are used to enhance the molding performance and mechanical strength of the catalyst.
Mixing
Add the active component raw materials,carrier raw materials,auxiliary raw materials and an appropriate amount of binder and solvent(such as water)to the inclined intensive mixer equipment.
The various raw materials are fully mixed by mixing to form a uniform mixture.During the mixing process,parameters such as mixing time,temperature and mixing speed need to be controlled to ensure the uniformity of the mixing.
Molding
Extrusion molding:The mixed material is made into a mud-like material with a certain plasticity,and then extruded into the desired shape,such as honeycomb,column,etc.through an extruder.During the extrusion process,the extrusion pressure,speed and mold size need to be controlled to ensure the shape and dimensional accuracy of the catalyst.
Drying
The formed catalyst body is placed in a drying device for drying.
Calcination
The dried catalyst body is placed in a calcining furnace for high-temperature calcination.
Post-processing
Cutting and grinding:For some catalyst products that require specific sizes,such as honeycomb catalysts,cutting and grinding are required to ensure their dimensional accuracy and surface quality.
Quality inspection:Comprehensive quality inspection of the produced catalysts,including physical and chemical performance inspections.
Packaging:The qualified catalysts are packaged for storage and transportation.The packaging material should have good moisture-proof and anti-pollution properties.

Performance advantages of SCR denitration catalyst inclined intensive mixer

•Efficient mixing:It can achieve highly uniform mixing of various components of SCR denitration catalysts in a short time,greatly improving production efficiency and reducing mixing time and energy consumption.
•High mixing quality:The active components,carrier materials,additives,etc.in the catalyst can be evenly dispersed to ensure the consistent performance of each part of the catalyst during use,improve the efficiency and selectivity of the denitration reaction,and reduce the uneven local reaction.
•Strong adaptability:By adjusting parameters such as mixing speed,mixing time,and blade shape,it can adapt to the mixing needs of materials of different types and properties.Whether it is high-viscosity or low-viscosity materials,or powders,particles or slurries of different particle sizes,good mixing effects can be achieved.
•Easy operation:The operating interface of the equipment is simple and easy to understand,with a high degree of intelligence,which reduces the difficulty and labor intensity of the operator's work,and also reduces the impact of human operating errors on the mixing quality3.
•Low maintenance cost:The structure is relatively simple,the main components are sturdy and durable,and easy to disassemble and repair.The daily maintenance workload is small and the maintenance cost is low,which can ensure the long-term stable operation of the equipment.
