NINGBO T.C.I Baffle demister. Demister. Also called wave plate demister. The demister.
In the process of industrial production and industrial emissions in the process, the gas liquid separation is an important technological process.In many products of the production operation to be entrained in the gas phase of the mist or dust to be separated, in order to make the normal production smoothly.While the mist or dust particle diameter is very small, such as mechanical generated mist particle diameter in 1 ~ 150 μ m, and cohesion produces entrainment particles with diameters of 0.10 ～ 30 μ m, separating the mist or dust, both to the high separation efficiency, small resistance, not easy to block, even a small mounting area, running the economy, safety and reliability, convenient operation.
The demister working principle diagram
In order to clear the gas in the entrainment and entrained liquid phase, industrial production in the general use of the demister.The demister is a kind of industrial production and environmental protection industries widely used in gas - liquid separation essential device.Early in the last century thirty's, the people in order to the needs of industrial production have invented the demister.According to the mist eliminator for the purpose or structure can be divided into many types, such as the louver separator, gravity type separator and the cyclone separator, the separating efficiency of separator is not high, and not easy to separate, smaller size of mist; wire-mesh demister although can be separated from general mist, but requires the mist cleaning smaller, airflow velocity, and pressure drop is big, short service life, large equipment investment.Therefore, the research and production of high separation efficiency, low pressure drop, allowing high airflow speed, anti-blocking function strong new effective demister become the industrial production the urgent need to solve the problem.
When the entrainment gas to a certain speed through the mist eliminator, due to gas inertia impact, entrainment and wave plate phase collision which is attached to the corrugated plate surface.Corrugated plate surface diffusion, mist entrainment gravity settling the mist to form larger droplets and with the air moves forward to corrugated plate bends, due to the centrifugal force and the corrugated plate friction, adsorption and surface tension of the liquid makes the droplet growing, until the concentration drops to its own gravity over gas lift and the liquid surface tension force, the droplet from the corrugated plate surfaces are separated.The demister corrugated plate of foldable structure increases the entrainment is trapped opportunities, not removed by entrainment in the next corner after the same role and arrested set, this repeated action, thus greatly improving the demisting efficiency.Gas through the corrugated plate demister, basically not containing mist.
Corrugated plate demister separation device usually consists of foldable corrugated plate, supporting frame, a baffle and the flushing nozzle, flushing pipes, pipe supports, pipe clamp components.
The separation step:
A gas into the mist eliminator was divided into many single unit channel;
B in inertial force, droplet entrainment collisions in a wave plate forming liquid film;
C liquid film along the airflow corner forward movement to break dow
