Description
Technical field
Technical field of desulfurization is the utility model is related to, more particularly to a kind of efficiently silk screen demister.
Background technology
Flue gas is formed by that after wet desulfurizing process, still can contain dust particle and carry some desulfurizing agents secretly
Particulate matter and steam etc., therefore, in order to meet emission request, it is necessary to set demister after sulfur removal technology, to above-mentioned
Grain thing is intercepted, and at present, there is following several conventional demister in domestic wet desulfuration tower：
(1) deflection plate demister：This kind of demister separator generally by Multifolding Corrugated Plate, support frame, baffle plate and
The parts such as flooding nozzle, flushing pipe, pipeline support, pipe clamp form.When the gas containing mist flows through demisting with certain speed
During device, because the inertial impaction of gas acts on, mist collides and is attached in waveform plate surface with corrugated sheet.Corrugated sheet table
The diffusion of mist, the gravitational settling of mist make mist form larger drop and move forward to corrugated sheet turning with air-flow on face
Place, due to turning to centrifugal force and its make it that drop is more next with the surface tension of the rubbing action of corrugated sheet, suction-operated and liquid
It is bigger, until the drop gathered arrives greatly its own caused gravity more than the climbing power of gas and making a concerted effort for surface tension of liquid
When, drop just is separated from waveform plate surface.Although demister corrugated sheet be folded to structure and add mist be caught
The chance of collection, but must continuous repeated action, could progressively remove droplet, its intercepting efficiency is low, short life, long in time limit.
(2) bundled tube demister：This kind of demister flue gas produces centrifugal motion, in centrifugal force by eddy flow molecular separator
In the presence of, droplet moves with dirt to staving wall.In the process of running, mutual perikinetic aggregation is thrown into larger drop, drop
To interior bucket wall surface, contact with the drop layer of wall attachment it is latter fall into slurries together, realize the removing of droplet and dirt.Equally have
Intercepting efficiency is low, the pressure loss is big, easily blocking, short life, it is long in time limit the shortcomings that.
(3) wet electric dust-removing：The operation principle of wet electric dust-removing is similar with dry type, be all high-voltage corona discharge make dust or
Water fog charge, charged particle reach collecting plate, but the wet electric dust-removing in the reset mode of dust in the presence of electric field force
Electrode is rinsed using liquid is washed away, the dust captured on dust collection plate is washed into ash bucket and discharged therewith.Although this kind of method intercepts
Efficiency high, but its investment cost, maintenance cost, operating cost be high while short life, long in time limit.
