These filters are constructed from materials like fiberglass or synthetic fibers, designed to withstand high temperatures while maintaining low resistance to airflow.

Process of High Temperature Filters

Selection of Raw Materials
The core materials of high temperature filters are ceramics, graphite, high temperature alloys, etc. These materials have excellent high temperature and corrosion resistance, and can ensure the filtering effect.

Preparation of Filter Element
The raw materials are made into the required filter element shape. The commonly used filter element shapes are tubular, plate-shaped, cylindrical and sheet-shaped. Choose the appropriate filter element shape according to different usage requirements.

Baking
After molding, the filter element needs to be baked at high temperature to eliminate internal stress and enhance its strength.

Sintering
Spray high temperature corrosion-resistant ceramics and other heat-resistant materials on the surface of the filter element, or inject, impregnate and other composite processes to make it an integrated filter element, so as to achieve the effect of high temperature resistant filtration.

Finished Product
After the sintering process, the high temperature filter becomes a complete filter product, which can be customized according to different usage requirements, such as filtration accuracy, filtration area, etc.

A: High temperature filters mainly use the physical, chemical and high temperature effects of filter materials at high temperatures to decompose and degrade pollutants into harmless and easy-to-handle substances, thereby achieving efficient filtration. Its main working principles are as follows: (1) Pyrolysis: At high temperatures, some toxic organic matter and organic substances can be decomposed into harmless substances through pyrolysis, thereby achieving decomposition and degradation. (2) Oxidation: Through high temperature oxidation reactions, organic matter, odors and toxic substances are decomposed into CO2 and H2O, thereby achieving efficient filtration. (3) Adsorption: The surface of the filter material has an adsorption effect and can absorb organic matter and gas particles, thereby achieving filtration and decomposition.

Q: What is the service life of a high temperature filter?

A: The service life of a high temperature filter is affected by many factors, such as the filter's material, structure, use environment, and working conditions. Generally speaking, the service life of a high temperature filter is about 1500 to 2000 hours, but the actual use time will vary due to some external factors, such as rough pipes or oxides in the pipes, which will cause dirt to adhere to the filter surface, thus affecting the service life of the filter. In addition, if the filter is always in a high pressure difference state, it will also accelerate the damage of the filter.

Q: What should be paid attention to before using the high temperature filter?

A: First, the installation location of the filter should meet the design requirements, and avoid installation in a high temperature, humid or corrosive environment. Secondly, during the installation process, the installation instructions should be strictly followed to avoid damage to the filter or improper installation. Thirdly, after the installation is completed, performance testing and verification should be carried out to ensure that the performance of the filter meets the design requirements.

Q: What is the performance change of high temperature filters?

A: In a high temperature environment, the performance of high temperature filters will change, affecting the filtration efficiency and life. Generally speaking, excessively high temperatures can cause deformation, aging or melting of the filter material of the high temperature filter, thereby affecting its filtration efficiency and service life. In addition, in a high temperature environment, the adhesive, sealant and other materials inside the filter may fail, thereby affecting its sealing performance. Therefore, when using a high-efficiency filter in a high temperature environment, special attention should be paid to its temperature resistance and use conditions.
