Description
Technical field
This utility model is related to demister apparatus field, more particularly to a kind of antifogging device of adjustable speed.
Background technology
In wet desulphurization, absorption tower is also easy to produce " mist " that particle diameter is 10--60 microns in running, and " mist " not only contains
There is moisture, it is also dissolved with sulphuric acid, sulfate, sulfur dioxide etc., while also resulting in staining and tight for blower fan, heat exchanger and flue
Heavy corrosion, therefore, on wet desulfurizing process to absorption equipment propose demisting requirement, cleaned gas leave absorption tower it
Before want demisting.
Demister is used for the drop of gas entrainment in knockout tower, to ensure to have mass-transfer efficiency, reduces valuable material and damages
Becoming estranged improves the operation of compressor after tower, general many to arrange demister in tower top.The droplet of 3--5um can be effectively removed, between tower tray
If arranging demister, can not only ensure the mass-transfer efficiency of tower tray, plate spacing can also be reduced.So demister is mainly used in gas-liquid
Separate.Also can separate for gas for air filter.
" mist " that wet desulphurization is produced, also dissolved with sulphuric acid, sulfate, sulfur dioxide etc..If do not properly settled, any entrance
" mist " of chimney, actual is exactly sulfur dioxide (SO2) emissions in air, while also resulting in staining for blower fan, heat exchanger and flue
And heavy corrosion.Therefore, the requirement of demisting is proposed on wet desulfurizing process to absorption equipment, cleaned gas is leaving absorption
Demisting is wanted before tower.Demister is the key equipment in FGD systems, and can its performance directly influences wet FGD system continuous
Reliability service.Demister failure not only results in the stoppage in transit of desulphurization system, in some instances it may even be possible to cause whole unit（System-down）.
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 arrived greatly the gravity of its own generation more than the climbing power and surface tension of liquid of gas by poly- drop
When with joint efforts, drop is just separated from waveform plate surface.Demister corrugated sheet be folded to structure and increased mist be caught
The chance of collection, the mist not being removed are acted on through identical at next turning and are captured, such repeated action, so as to
Substantially increase demisting efficiency.Gas is substantially free of mist after wave-shaped plate demister.Bending of the flue gas by demister
Passage, in the presence of inertia force and gravity by the drop separation carried secretly in air-flow out：Flue gas after desulfurization is with certain speed
Degree flows through demister, and flue gas is rapidly, continuously changed the direction of motion, and because of the effect of centrifugal force and inertia, the droplet in flue gas hits
Hit, droplet collects to form current, because of the effect of gravity, under drop down onto in slurry pool, realize
Gas-liquid separation so that the flue gas for flowing through demister reaches after demisting is required and discharges.
In the gas encountered in common chemical industry operation, the diameter of dispersant liquid drop is about at 0.1～5000 μm.General grain
Granule of the footpath more than 100 μm is very fast because of sedimentation velocity, and its separation problem is easy to solve.Liquid of the general diameter more than 50 μm
Drop, can be separated with settling methods；More than 5 μm of drop can use inertial collision and centrifugal separation；For less mist then
Try to make its aggregation to form larger particles, or with fabric filter and electrostatic precipitator.

And the impurity for sticking to sheet surface is taken away.This makes it possible to ensure the demisting ability of this device.
The demisting efficiency of demister increases with the increase of air velocity, and this is, as flow velocity is high, to act on droplet
Inertia force is big, is conducive to the separation of gas-liquid.But, the increase of flow velocity will cause SR to increase, and also increase energy consumption.And
The increase of flow velocity has certain limit, and flow velocity is too high to cause two sub-band water, so as to reduce demisting efficiency.Generally will be by demisting
The highest of device section and and will not two sub-band water when flue gas flow rate be defined as critical flow velocity, the speed and demister structure, be
The factors such as regiment commander's Water l oad, airflow direction, demister arrangement are relevant.Design current velocity is typically selected in 3.5-5.5m/s.
Therefore, in order to increase demisting efficiency, this device is just provided with flow accelerator.Rotated by motor belt motor movable vane
It is dynamic, so as to accelerate to suction out gas, therefore the speed of air-flow is accelerated, so as to increased the demisting efficiency of demister.
Also, according to different practical situations, the demisting efficiency being optimal.This device is provided with various rotating speed.This dress
3 points of the belt wheel put is the first belt wheel 32, the second belt wheel 33 and the 3rd belt wheel 34, and in same time only one of which belt wheel and motor
It is connected and by the motor-driven rotation.The diameter of the first belt wheel 32, the second belt wheel 33 and the 3rd belt wheel 34 is once incremented by, therefore
When they are connected with motor respectively, when impeller 35 is rotated, the rotating speed of impeller 35 successively decreases successively.Namely when the first belt wheel
32 when being connected with motor, and the rotating speed of impeller 35 is maximum；I.e. when the 3rd belt wheel 34 is connected with motor, the rotating speed of impeller 35 is minimum.
So arrange, the air velocity of this device can be just distributed in 3.5-5.5m/s, also, according to actual needs,
It is adjusted, so as to reach optimal demisting efficiency.Because this device has the different belt wheel of three diameters, therefore in order to more
Plus good cooperation, the quantity of belt 41 is also three, the different belt wheel of corresponding matching.
This device is provided with the device of clean demisting group, therefore, intake section 221 is set on right-angle elbow pipe 22 just, also,
In order to prevent liquid from entering in right-angle elbow pipe 22, the passage on intake section 221 is arranged on the wall of side.
Connected by belt 41 between the motor 4 and belt wheel 3 of this device, so as to realize V belt translation.This device is being opened
During beginning work, motor 4 is rotated with movable belt pulley 3, so that impeller gyrates, the gas in impeller portion 31 is passed through outlet
Pipe 23 is discharged, then again by the gas inspiration impeller portion 31 in right-angle elbow pipe 22.
The air inlet pipe 21 of this device connects external trachea, so as to the gas for carrying out demisting work will be needed to be linked into into gas storehouse
In 11.The gas is then passed through demisting group 2, after demisting process is carried out by the demisting group 2, is pooled to out at gas storehouse 12.Finally,
These gases can be guided by right-angle elbow pipe 22, are entered into impeller portion 31, and are discharged.
