I. IntroductionWith the rapid development of industrial technology, there is an increasing demand for air filtration in high temperature environments. High Temperature Air Filter (High Temperature Air Filter) as the key equipment in this field, plays a vital role. The purpose of this paper is to introduce the definition, working principle and importance of high temperature air filter in detail.
Definition

High Temperature Air Filter is a specially designed air filtration equipment, which can effectively filter solid particles, oil mist, soot and other pollutants in the air under high temperature environment. Its design features include high temperature resistance, corrosion resistance, high efficiency, etc. to ensure stable and reliable operation under high temperature working conditions.
Working Principle
The working principle of high temperature air filter is mainly based on two mechanisms: physical filtration and adsorption filtration.
Physical filtration:Physical filtration is the main filtration method of high temperature air filters. When the air passes through the filter, the particles in the air will be resisted and be retained on the filter media. The filter media is usually made of high temperature resistant fiber materials, such as glass fiber, ceramic fiber, etc.. These materials have good high temperature resistance and filtration efficiency, and can effectively intercept airborne particles.
Adsorption filtration:In addition to physic
