Description
Technical field
The invention belongs to waste gas dedusting technical field, and in particular to a kind of bipolar charge coalescence for dust granules fills
Put.
Background technology
With the rapid development of the national economy, China some areas haze takes place frequently, arch-criminal is airborne particulate pollution
Thing.Aerodynamically diameter（da）Size, airborne particulates can be divided into overall suspended pellet（TSPs, da<
100 μm）, pellet（PM10, da<10 μm）And lung particulate matter（PM2.5, da<2.5 μm）.With it is thicker big
Aerated particle pollutant is compared, and PM2.5 particle diameter is small, is adsorbed with substantial amounts of poisonous and harmful substances, can be by blood and tissue
Absorb, and residence time length, fed distance in an atmosphere is remote, the influence to health and atmosphere quality is bigger.Combustion
The dust granules that the industries such as coal power generation, coal chemical industry, waste incineration, metallurgy, cement pass through air flue emission are airborne particulates
One of main source.Because the dedusting technology removal efficiency of PM2.5 particle diameter little tradition is relatively poor, at present mainly from two sides
Its its removal efficiency is improved in face, first, traditional dedusting technology is improved, but effect is effective；Second, pass through coalescence（Cohesion is reunited）'s
Little particle coalescence into bulky grain, thus traditional dedusting technology can be used to strengthen the molecules such as removing PM2.5 by method, latter
Kind method is the emphasis competitively developed at present.
The coalescence method of current dust granules include sound wave coalescence, coagulation simultaneously, magnetic coalescence, chemical coalescence, steam phase transforming
The technologies such as coalescence, wherein coagulation and research are more goed deep into, application prospect is larger.Again with bipolar charge-rapids in electric coagulating technique
Stream coagulating technique most has industrial applications prospect, and its general principle is as shown in Figure 1.Bipolar charge-turbulent flow coalescence device is
The pipeline of one section of rectangle, the pipeline are divided into bipolar charge section and turbulent flow coalescence section two parts.Bipolar charge section is one group of positive and negative electricity
The parallel channels of field action, when gas containing dust granules is by this section, positive and negative by its passage obtains positive charge and negative electrical charge respectively,
Subsequently into turbulent flow coalescence section coalescence；Turbulence columns or votex sheet are set in turbulent flow coalescence section（Accompanying drawing 1 is set in vertical paper direction
Turbulence columns are put）, for strengthening air-flow by less turbulence at this section, so as to increase the collision probability between charged particle,
Improve coalescence efficiency.The Basic Mechanism of bipolar charge-turbulent flow coagulating technique is that bipolar charge particle realizes sky under turbulent flow
Between large scale conveying and mixing, in the collision of Kolmogorov yardsticks, coalescence, and Coulomb force rises in short distance to particle coalescence
To facilitation.
Particle coalescence easily occurs, in the big polydisperse system of particle diameter difference, also easily to occur in the heteropole acted on Coulomb force
Property electrically charged particle between, based on above-mentioned 2 reasons, realize that " the selectivity mixing " of different-grain diameter particle just can guarantee that turbulent flow is coagulated
And high efficiency；So-called " selectivity mixing " refer in air-flow the fine grained of lotus positive electricity with from the outflow of adjacent negative polarity passage
The bulky grain of bear electricity mixes, the bulky grain of the fine grained of bear electricity and the lotus positive electricity from the outflow of adjacent positive polarity passage in air-flow
Mixing；Due to the complexity of turbulent flow in itself so that what design can realize different-grain diameter particle " selectivity mixing " turns into a difficulty
Point.
