Mist Eliminator Information
Mist eliminators are used to separate droplets carried by the flue
gas. In the absorption tower, it consists of upper and lower
secondary demisters (horizontal or diamond or herringbone) and
flushing water system (including pipes, valves and nozzles, etc.).
The purified flue gas flows through the two-stage mist eliminator,
and the slurry droplets carried by it are removed. The small
droplets separated from the flue gas slowly condense into larger
droplets, and then slide down the mist eliminator blades to the
slurry pool. There are a set of headers with nozzles on the upper
and lower parts of the primary demister and the lower part of the
secondary demister. Mist eliminators in the header The cleaning
water passes through the nozzles to flush the solid particles
deposited in the demister in turn. After washing and purification,
the flue gas flows out of the absorption tower and is finally
discharged into the chimney through the flue gas heat exchanger and
the clean flue.
Selection Of Installation Form Of Mist Eliminator
The wire mesh demister is divided into top-loading type and
bottom-loading type. When the manhole is located above the wire
mesh demister, the top-mounted wire mesh demister is selected; when
the manhole is located below the wire mesh demister, the
bottom-mounted wire mesh demister is selected.
According to the structural design of the gas storage container,
the wire mesh demister should be installed above the manhole, so
the bottom-mounted installation structure is adopted.
Mist Eliminator demister effect
The gas-liquid separation efficiency of the wire mesh demister
consists of two parts, namely the direct interception and
separation efficiency and the inertial impact efficiency.
(1) Direct interception
When the gas flows through the wire mesh structure, if the droplets
in the gas are larger than the pore size of the wire mesh
structure, they will be intercepted by the pores and separated. If
the droplets hit the screen directly, they will also be
intercepted. Direct interception can collect - a certain number of
particles smaller than their pore size
(2) Inertial impact
A droplet has mass and velocity in a flowing gas, so it has
momentum. When the gas and the droplets entrained by it pass
through the wire mesh, the gas will choose the channel with the
least resistance to flow through, and will change direction along
the wire mesh structure, that is, the streamline will be deflected.
Because the droplets have momentum, the larger droplets still move
forward in a straight line due to inertia, so that the droplets
located in the center of the airflow or close to the center of the
airflow are thrown or impacted on the screen and separated. In
gas-liquid separation, the effect of inertial impact on large
droplets with a particle size larger than 20 μm is obvious.
