[0002] Dust filtration refers to the process of separating and removing dust particles in the air through specific equipment or materials. This process usually involves various types of dust filters, which use different working principles and technologies, such as gravity sedimentation, screening, collision, hooking, diffusion and electrostatic force, to effectively capture and remove dust particles in the air. Dust filtration is of great significance to improving air quality, protecting the environment and ensuring people's health. In order to enable enterprises to better achieve standard emissions and create an environment that is more suitable for employee production and equipment operation, dust filtration is required in heavy dust environments, and dust filtration requires the use of micro-nano fiber membrane filtration devices.
