[0018] By separating the material, the tiny liquid mist is captured and grows into large droplets, and then separated from the gas phase by gravity.
[0019] 1.1. Three interception mechanisms work together to capture droplets
[0020] The separation material forms a tortuous channel for the gas flow, forcing solid particles and liquid droplets to collide with the separation material under the action of three mechanisms of inertial collision, diffusion interception and direct interception.
[0021] Inertial collision refers to the collision of particles on the fiber due to inertia after the change of the direction of fluid motion. For particles of 2 μm and larger, due to their large mass and inertia, they maintain their original trajectory and collide with the fiber.
[0022] Diffusion interception is the main interception method for particles below 0.2 um in the gas. Due to Brownian motion, particles diffuse from the gas flow to the fiber surface and are adsorbed on the fiber under the action of static electricity.
[0023] For particles from 0.2 um to 2 um, only direct interception works. Direct interception refers to the interception of particles when their diameter is larger than the fiber channel. Direct interception is the most basic feature of pore size distribution, and the smaller the pore size, the higher the direct interception efficiency and the higher the particle removal efficiency.
[0024] 1.2. Liquid droplet flow direction: discharged to the bottom of the separator by gravity to prevent the formed liquid droplets from being broken and brought back into the gas flow by the gas.
[0025] 1.3, High-efficiency vane separator inner structure: using the multi-bending structure of the vane and special angle design, the gas carrying liquid droplets is forced to change the flow direction several times during passing through the vane area. Under the action of centrifugal force, the liquid droplets collide with the vane several times, and the liquid film is formed by the coalescence effect between the liquid droplets after the liquid droplets adhere to the surface of the vane. The liquid film adhering to the surface of the vane is pushed into the vane interlayer under the combined action of its own gravity, liquid surface tension and gas kinetic energy, and flows into the bottom of the separator under the action of its own gravity after converging into strands in the interlayer, and is finally discharged.
[0026] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
