Structure: Tubular microporous diffuser mainly consists of a support tube, an elastic microporous aeration membrane, clamps, sealing gaskets, an air inlet connector, and end caps at both ends; the support tube serves as a rigid skeleton for membrane support and airflow transmission, while the elastic microporous membrane covers the exterior of the support tube, secured and positioned by clamps to ensure airtightness. Both ends are sealed using gaskets and end caps, and the air inlet connector is used for connection with the air distribution branch pipe. The overall structure is compact, the sealing is reliable, and disassembly and maintenance are simple, meeting the requirements for long-term underwater aeration operation.

Working Principle: The tube microporous diffuser consists of an aeration main pipe, a support tube, an elastic microporous membrane, and matching connectors. During operation, compressed air delivered by the blower enters the inner cavity of the diffuser to create internal pressure. Once this internal pressure overcomes the external hydrostatic pressure and the elastic tension of the membrane, the membrane undergoes slight expansion and deformation, opening its micron-sized pores. The air is then sheared and broken through these micropores to form a uniform group of microbubbles. As the bubbles rise, they complete oxygen transfer and diffusion based on gas-liquid mass transfer principles, achieving efficient oxygenation of the water body. Simultaneously, the gas-liquid two-phase flow generated by the rising bubbles drives water circulation and mixing, ensuring the uniform distribution of dissolved oxygen and activated sludge. After the blower is shut down, the membrane relies on its own elasticity to rebound and close the micropores, effectively preventing sludge and water in the tank from backflowing and clogging the pipeline.
