Description
Technical field
The utility model relates to chemical fields, and in particular to a kind of High efficiency baffle plate demister.
Background technique
Drop of the demister for gas entrainment in knockout tower reduces valuable material damage to guarantee having mass-transfer efficiency
It becomes estranged the operation of compressor after improving tower, reduces water content, extend the service life of compressor, demister mostly generally is set in tower top.
The droplet of 3--5um can be effectively removed, if demister is arranged between tower tray, the mass-transfer efficiency of tower tray is not only can guarantee, can also reduce
Plate spacing.So wire mesh demister is mainly used for gas-liquid separation.Also it can be separated on air filter for gas.
Baffle plate demister demister is also known as wave plate demister demister in industrial processes and the row of industrial waste gas
During putting, by gas -- it is an important technical process that liquid, which carries out separation,.It will be pressed from both sides in many Product Process production operations
Band mist in the gas phase or dust are separated, and production can just normally successfully carried out.And mist or dust particles diameter
Very little, if the mist particle diameter of mechanicalness generation is between 1.0 ~ 150 μm, and the mist particle diameter that coherency generates exists
Between 0.10 ~ 30 μm, separate these mists or dust, should separative efficiency it is high, resistance is small, is not easy to block, also wants mounting area
Small, economical operation is securely and reliably, easy to operate.
In order to remove the mist in gas and the liquid phase of entrainment, demister is generally used in industrial production.Demister is one
Kind widely used gas in industrial production and environmental protection industry -- liquid separates essential device.Early in last century 30 years
Generation, people need just to have invented demister in order to industrial.Many kinds can be divided into according to the purposes of demister or structure
Class, such as louver separator, gravitational settling type separator and whirlwind board separator, but these separators are not high,
And it is not readily separated the mist compared with small particle;Although mesh mist eliminator can separate general mist, mist is required to clean, air-flow
Flow velocity is smaller, and resistance drop is big, and service life is short, and equipment investment is big.Therefore, research and production separative efficiency are high, resistance drop is small,
The high-efficient defroster that allowable superficial gas velocity is big, choke preventing function is strong becomes problem in the urgent need to address in industrial production.
When the gas containing mist flows through demister with certain speed, due to gas inertial impaction act on, mist with
Corrugated sheet collides and is attached in waveform plate surface.The diffusion of mist, the gravitational settling of mist make mist in waveform plate surface
Foam forms biggish drop and moves forward to corrugated sheet turning with air-flow, due to turning to centrifugal force and its rubbing with corrugated sheet
The surface tension of wiping effect, suction-operated and liquid makes drop increasing, until the drop gathered arrives greatly its own generation
Gravity be more than gas climbing power and surface tension of liquid resultant force when, drop is just separated from waveform plate surface.
The structures that are folded to of demister corrugated sheet increase the chance that mist is captured more, and the mist not being removed passes through at next turning
It crosses identical effect and is captured, such repeated action, to substantially increase demisting efficiency.Gas passes through wave-shaped plate demister
Afterwards, substantially free of mist.
Wave-shaped plate demister separator is usually by Multifolding Corrugated Plate, support frame, baffle and flooding nozzle, flushing pipe
The components such as road, pipeline support, pipe clamp composition.
Separating step:
A gas enters after demister the channel for being separated into many sub-threads;
For b under the action of inertia force, the collision of drop mist forms liquid film in corrugated sheet on piece;
C liquid film moves forward to turning with air-flow and is separated;
Existing baffle plate demister only only rises the formation liquid film on plate of collision later by gas and is finally separating, this
In the case of sample, foam removal effect is frequently not highly desirable；Meanwhile the liquid film of top formation can be continued below the gas and band of rising
It walks, will lead to the gas finally come out still has foam fog.
