[0002] In fields such as the hydropower industry, machinery manufacturing, industrial and mining enterprises, etc., pressure vessels are required to store compressed gas. During the maintenance process of pressure gas tanks, pressure relief is needed. The pressure relief is accompanied by high-frequency noise that affects occupational health, as well as problems such as oil mist and dust during the pressure relief process. In response to this series of problems, a safe and environmentally friendly pressure relief and noise reduction device has been developed. However, during the noise reduction process, the noise reduction device adsorbs oil mist and dust impurities, which will cause the noise reduction filling cotton filter element inside the noise reduction device to become saturated. For the problem of filter element saturation, the traditional method is to first stop the operation and disassemble the noise reduction device, then replace the internal noise reduction adsorption material, and then reassemble the noise reduction device. First, the whole process is cumbersome, the maintenance time is long, which affects the construction period and the cost is high. Secondly, the internal adsorption material of the noise reduction device is filled unevenly by manual labor. Finally, the filling adsorption material is single and only has the function of noise reduction. Some filling materials have a little function of adsorbing oil mist and impurities. Nowadays, it cannot meet the requirements of safe, environmentally friendly and high-efficiency noise reduction. Therefore, this application designs a multi-functional filter inner core structure for a noise reduction device to achieve quick replacement of the filter cartridge and adsorption filtration material inside the noise reduction device, so as to achieve the purpose of quicker, more environmentally friendly and higher-efficiency noise reduction.
