Description
Technical field
The invention belongs to waste gas dedusting technical fields, and in particular to the particulate matter coalescence of bipolar charge and sound wave synergistic effect
Device.
Background technique
With the rapid development of the national economy, China some areas haze takes place frequently, arch-criminal is airborne particulate pollution
Object.The aerodynamically size of diameter (da), 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 the partial size of PM2.5 is small, is adsorbed with a large amount of poisonous and harmful substances, can be by blood and tissue
It absorbs, and residence time length, conveying distance in an atmosphere is remote, the influence to human health and atmosphere quality is bigger.Combustion
The dust particles 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.Since the dedusting technology removal efficiency of the partial size little tradition of PM2.5 is relatively poor, at present mainly from two sides
Its its removal efficiency is improved in face, first is that improving traditional dedusting technology, but effect is effective；Second is that passing through coalescence (cohesion or reunion)
Little particle coalescence at 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.

Reason is as shown in Fig. 1.Bipolar charge-turbulent flow coalescence device is the pipeline of one section of rectangle, which is divided into bipolar charge section and rapids
Flow coalescence section two parts.Bipolar charge section is the parallel channels of one group of positive and negative electric field action, and gas containing dust particles passes through this section
When, positive and negative by its channel obtains positive charge and negative electrical charge respectively, subsequently into turbulent flow coalescence section coalescence；It is set in turbulent flow coalescence section
Turbulence columns or votex sheet (attached drawing 1 is to be provided with turbulence columns in vertical paper direction) are set, when for enhancing air-flow by this section
Less turbulence, to increase the collision probability between charged particle, improve coalescence efficiency.Bipolar charge-turbulent flow coagulating technique
Basic Mechanism is the conveying and mixing that bipolar charge particle realizes space large scale under turbulent flow, in Kolmogorov scale
Collision, coalescence, and Coulomb force plays facilitation to particle coalescence in short distance.
The present invention by bipolar charge-turbulent flow coalescence in conjunction with sound wave coagulating technique, with obtain preferably more collaboration particles
