Technical field
The present invention relates to demister, particularly relate to a kind of self-adapting type ball float demister and defogging method thereof.
Background technology
The demister flash distillation be widely used in the field such as chemical industry, environment takes off the processes such as mist, Oil-gas Separation, acid mist purifying.The demister used in flue gas desulphurization system is impacting type demister, in impacting type demister, drop catch by target and completed by inertial collision, directly interception and diffusion 3 kinds of mechanism.
After band shredded tobacco for water pipes gas enters demister, due to effect of inertia, flue gas flow direction changes, and the drop carried in flue gas, under centrifugal action, clashes into wall.Under the effect of sweep of gases, the liquid film on wall is collected in the flex point place be connected with next passage, formed after thicker cascade along under wall flow.In chevron mist eliminator, very tiny Particles Moving track is away from rectilinear.Therefore, flap demister is applicable to the separation of relative oversize grain, for tiny droplet particles, must apply the demister of other form.
At present, most domestic thermal power plant all adopts Limestone-gypsum Wet Flue Gas Desulfurization Process technique, accounts for more than 95% of desulphurization market share.If wet desulfurization system does not have easily to occur " gypsum rain " phenomenon during Smoke-heating device." gypsum rain " not only affects life and the production of plant area, but also can affect the life of neighbouring residential block, for environment brings adverse effect.Therefore desulphurization system takes corresponding measure to administer " gypsum rain " just to become quite important in design and running process.
The design of the demister in wet desulphurization tower not only requires to have efficient separating property, also requires lower crushing, good good antiscale property, anti-clogging, corrosion resistant, convenient cleaning and maintenance etc.Should consider with combined factors such as the designing requirement of whole desulphurization system, system operation conditions, operating flexibility, desulfurizing tower fouling, desulfurizing agent kind, the kinds of washing slurries and fire coal during design.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming above-mentioned prior art, a kind of self-adapting type ball float demister and defogging method thereof are provided.Solve traditional demister demisting efficiency low, the problems such as equipment investment is large, overhaul of the equipments is difficult, pressure drop is large.
The present invention is achieved through the following technical solutions:
A kind of self-adapting type ball float demister, is comprised demister housing 1, arranges multilayer floater shot demisting unit 3 in demister housing 1, separated between each floater shot demisting unit 3 by sieve plate 2; Each floater shot demisting unit 3 is piled up by multiple ball float and is formed.
Described ball float is hollow float.
Described sieve plate 2 is deflection plate, silk screen or perforated panel.
The top of described floater shot demisting unit 3 and/or transfer the spraying layer 5 be provided with for cleaning ball float and sieve plate 2.
Described ball float is made up of macromolecular material.
Described floating ball diameter is 50mm ~ 80mm.
Described demister housing 1 is provided with dodge gate 4 corresponding on the sidewall of floater shot demisting unit 3.
The defogging method of above-mentioned self-adapting type ball float demister is as follows:
Air-flow is by entering in demister housing 1 bottom demister housing 1, floater shot demisting unit 3 is entered through sieve plate 2, the ball float piled up in floater shot demisting unit 3 under airflow function is floating state, the air-flow meanwhile risen runs into floating ball float, under the effect of inertia and baffling, airflow direction offsets, and the drop carried in air-flow and solid particle are constantly by ball float adsorption, cohesion, and the air-flow removing drop and solid particle is discharged by demister top; Thus complete self-adapting type demist.
The present invention, relative to prior art, has following advantage and effect:
Air-flow enters in demister housing by demister housing bottom, floater shot demisting unit is entered through sieve plate, the ball float piled up in floater shot demisting unit under airflow function is floating state, the air-flow meanwhile risen runs into floating ball float, under the effect of inertia and baffling, airflow direction offsets, and the drop carried in air-flow and solid particle are constantly by ball float adsorption, cohesion, and the air-flow removing drop and solid particle is discharged by demister top; According to the size of throughput and the uniformity coefficient in flow field, ball float can move under buoyancy, and then regulates flow field, thus reaches the object in self adaptation flow field.
Ball float adopts macromolecule hollow beads, not only reduces equipment investment, and improves demisting efficiency.Demister housing is provided with dodge gate corresponding on the sidewall of floater shot demisting unit, and easy access and replacing ball float, reduce further the difficulty of maintenance, make maintenance more convenient.
The present invention has good self-adapting type, not easily blocking, easily flushing, adaptability for working condition is strong, and demisting efficiency is high, and the feature that small investment, operation and maintenance cost are low, and effectively reduce the generation of wet desulphurization chimney gypsum rain.
