Application:

High-temperature resistant high-efficiency filters are air purification devices specifically designed for high-temperature and special working conditions. Their core components can operate stably for extended periods in environments ranging from 250℃ to 350℃. They are primarily used in the following scenarios and industries:

I. Conventional Civil/Food and Pharmaceutical Cleanroom Scenarios
This is currently the most widely used scenario, meeting the clean production standards of the food and pharmaceutical industries:

*Pharmaceutical Industry: Used in core production equipment such as high-temperature sterilization tunnels, clean ovens, and high-temperature clean air ducts in pharmaceutical plants. They filter out 0.3μm-level microparticles and microorganisms from the air during drug drying and sterilization processes, preventing drug contamination, meeting GMP production standards, helping companies pass regulatory inspections, and protecting the internal heat exchange components of the equipment, extending its lifespan.

*Food Processing Industry: Used in high-temperature food baking lines, drying equipment, and high-temperature sterilization processes. They filter impurities in high-temperature fresh air, preventing secondary contamination of food during processing and sterilization, ensuring food safety, and can operate stably at 250℃ for extended periods.

* * **Coating Industry:High-temperature fresh air filtration for ovens, meeting the clean air requirements of paint drying processes, suitable for high-temperature drying conditions after paint baking and spraying.

II. General Industrial Energy Scenarios
These scenarios rely on the structural stability of high-temperature resistant filters, suitable for dust recovery and purification under high-temperature conditions:

**Catalyst and Precious Metal Recovery:** Filtering and recovering catalyst particles, as well as precious materials such as nickel, platinum, industrial silicon, and specialty pharmaceutical raw materials in fluidized bed reactors. This solution is already widely and successfully implemented in factories worldwide.

**Waste and Waste Treatment:** Used for dust filtration in high-temperature flue gas in pharmaceutical waste and municipal solid waste incineration projects, intercepting harmful particulate matter in the incineration flue gas and reducing emissions.

**Energy Production:** Applied at the boiler outlet of pressurized fluidized bed coal burners and in coal gasification processes, filtering dust and slag particles from the syngas after gasification. The filtered clean gas can be directly supplied to gas turbines for power generation, significantly improving energy efficiency; it can also recover the heat from the combustion gases, further improving energy utilization.

III. Other Special Industrial Scenarios

**Production and Calcination:** Suitable for dust recovery and filtration during the calcination of materials such as magnesium oxide, reducing material waste and dust emissions.

**Power Exhaust Gas:** Suitable for capturing high-temperature smoke particles from diesel engine exhaust, improving exhaust gas cleanliness.

**Electronics Industry:** High-temperature resistant high-efficiency filters are also used in clean production processes of certain high-temperature operations to meet the cleanliness requirements of special temperature conditions.
