Honeycomb denitrification catalyst mold design

As an effective nitrogen oxide (NOx) control technology, SCR (Selective Catalytic Reduction) technology has been widely used in coal-fired power plants, steel plants, cement plants and other industrial fields. Among them, the honeycomb denitrification catalyst is the core component of SCR technology, and its performance and service life directly affect the efficiency of the denitrification system. The design of the honeycomb denitrification catalyst mold is particularly important.

The importance of honeycomb denitrification catalyst molds

Honeycomb denitrification catalyst mold is the key equipment for manufacturing catalyst carriers. The design of the mold is directly related to the geometry, porosity, specific surface area and other parameters of the catalyst support, which have a significant impact on the activity, thermal stability and sulfur resistance of the catalyst. Designing an efficient and durable honeycomb denitrification catalyst mold is the key to improving the performance of the SCR system.

1. Selection of mold materials

Selecting the right mold material is the basis for ensuring the performance of the catalyst carrier. Commonly used mold materials include stainless steel, aluminum alloy, etc. Stainless steel has excellent corrosion resistance and mechanical strength, and is suitable for the manufacture of catalyst carriers in high-temperature and high-pressure environments. Aluminum alloys, on the other hand, have advantages in some specific applications due to their light weight and good thermal conductivity.

2. Mold structure design

The structural design of the honeycomb denitrification catalyst mold needs to consider the geometry and porosity of the catalyst support. Reasonable mold structure can improve the specific surface area of the catalyst support, thereby enhancing the activity of the catalyst. The design of the mold structure should also take into account the feasibility of the manufacturing process to ensure the machining accuracy and production efficiency of the mold.

3. Mold life management

The service life of the mold has a direct impact on the production cost of the catalyst carrier. By optimizing the mold material, improving the mold processing accuracy, and adopting advanced heat treatment technology, the service life of the mold can be effectively extended and the production cost can be reduced.
