[0031] In use, the inlet pipe 3 is first connected to the exhaust gas pipe generated during wafer manufacturing. The exhaust gas is then transported to the processing chamber 2 through the inlet pipe 3. The exhaust gas is filtered through the glass fiber filter plate 8, where impurities are blocked and fall into the collection drawer 5. The glass fiber filter plate 8 effectively blocks dust and particulate matter in the exhaust gas, preventing them from entering subsequent processing equipment. Its multi-layer structure design makes the filtration effect more significant, capable of blocking, impacting, diffusing, and absorbing fine particulate matter. It also has high temperature resistance and corrosion resistance. The exhaust gas then passes through the HEPA filter plate 9 and the honeycomb ceramic filter plate 10. The HEPA filter plate 9 effectively filters pollutants such as particles, bacteria, and viruses in the air. Through its multi-layer fiber structure, it intercepts fine particulate matter, achieving a purification rate of 99.7% for particles of 0.1 microns and 0.3 microns. The honeycomb ceramic filter plate 10... The ceramic filter plate 10 has a porous structure, which can filter out fine particulate matter in the exhaust gas. This structure can not only effectively remove particulate matter, but also discharge the filtered gas through the duct 4. The collection drawer 5 is moved out of the treatment box 2 by the pull plate 7 and the mounting block 6. The collection drawer 5 drives the guide block to slide in the inner cavity of the guide groove 11, which effectively prevents the collection drawer 5 from tilting or shaking when it moves, and facilitates the cleaning of the inside of the collection drawer 5.
