Need flue gas that there is certain aridity, otherwise a large amount of drop can cause secondary dangerous hidden danger.Current existing gas-liquid point
It can be divided into Gravity Separation, inertial separation, cyclonic separation, electrically separated, filtering, fibre web separation etc. six by operation principle from device
Kind.
Enlargement is arranged in gravitational separation device on gas flow, and after gas flow rate reduces, drop is under the effect of gravity
Sedimentation separation.Gravitational separation device simple structure is reliable, but bulky, and can be only used for the separation of large scale drop.
Baffle is arranged in inertial separator on gas flow, and gas is obstructed by baffle, drastically changes flow direction, drop
Because of effect of inertia, change in travel direction is less than air-flow change in travel direction, impinges upon on baffle, to realize separation.Inertia point
From device simple structure, pressure loss is relatively small, but can only be used in the drop of separation large scale.
Gas is introduced tangentially into cylinder by cyclone separator, and gas high speed rotation within the barrel, drop is because of centrifugation
Effect is got rid of to cylinder inner wall by air-flow and realizes separation.This separator is simple in structure, good separating effect, but require gas have compared with
High flow velocity.
High-pressure electrostatic electrode is arranged in gas flow both sides in electrically separated device, forms electric field, and gas is flowed through from electric field, band
There is the drop of charge by electric field action, by electrode separation.Electrically separated unit efficiency is higher, can remove small scale drop, but right
The dielectric constant of drop there are certain requirements.In addition, civilian occasion, high-voltage electricity has certain danger.
Strainer removal drop is arranged in filtering classification device in gas flow, and strainer is small, and it is big to remove all
Drop in strainer effective aperture.Chinese patent CN201621134449 refers to a kind of gas-liquid filteration separator, solves existing
Have horizontal filter separator complicated, have a single function and problem that gas-liquid separation is inefficient, but high-precision strainer resistance compared with
Greatly, and it is easy to block, practical value is smaller.
Fibre web separator forms multiple large aperture strainer using fiber in certain thickness space and constructs, but again
Strainer is less efficient to droplet capture, and multiple structure can theoretically obtain arbitrary high removal rate.Actually typical fiber
Silk screen separator thickness is generally higher than 99.7%, the pressure loss is general generally in 100mm or more to the removal rate of fine drop
In 200-1000Pa ranges.For the higher gas of fine drop content, fibre web separator resistance usually increased.
If drop is unholiness, after long-time service, there is also the risks of blocking or fouling for fibre web.
