Description
Technical field
The invention belongs to waste gas dedusting technical field, be particularly used for the bipolar charge-cyclonic separation of flue gas dedusting
Device.
Background technology
Along with developing rapidly of national economy, China's some areas haze takes place frequently, and arch-criminal is that airborne particulate pollutes
Thing.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) can be entered.Big with thicker
Aerated particle pollutant are compared, and the particle diameter of PM2.5 is little, are adsorbed with substantial amounts of poisonous and harmful substances, can be by blood and tissue
Absorbing, and time of staying length in an atmosphere, fed distance are remote, the impact on health and atmosphere quality is bigger.Combustion
The industries such as coal power generation, Coal Chemical Industry, waste incineration, metallurgy, cement are airborne particulates by the flue gas of air flue emission
One of main source.Cyclone separator is the equipment utilizing centrifugal force to be separated from air-flow by granule, has simple in construction, separation
Efficiency is high, pressure drop is moderate, the advantage adapting to the harsh operating mode such as high temperature, high pressure, high granule density, is widely used in the preliminary of flue gas
Dedusting.Modern efficient cyclone separator can more than Ex-all 10 μm granule, granules more than 5 μm is also had preferably trapping
Ability.Along with improving constantly of flue gas emissions standard, conventional cyclone needs combined highly effective cleaner (as cloth bag removes
Dirt, electrostatic precipitation, electric bag dust) carrying out multistage dedusting could qualified discharge.But, the unit dedusting expense of high-effective dust-removing equipment
Also big, if improving the cyclone separator capture rate to the 10 following fine particles of μm, the negative of follow-up cleaner just can be reduced
Lotus, effectively reduces dedusting total cost.The most how to improve the cyclone separator capture rate to the 10 following fine particles of μm, become
For a problem demanding prompt solution in current gas-solid two phases technical research.
The method developing into exploitation strengthening cyclonic separation removing fine particle of bipolar charge-turbulent flow coagulating technique provides
New thinking, its ultimate principle is as shown in Figure 1.Bipolar charge-turbulent flow coalescence device is the pipeline of one section of rectangle, and this pipeline divides
For bipolar charge section and turbulent flow coalescence section two parts.Bipolar charge section is the parallel channels of one group of positive and negative electric field action, and granule leads to
When crossing this section, positive and negative by its passage obtains positive charge and negative charge, respectively subsequently into turbulent flow coalescence section coalescence；Turbulent flow coalescence
Turbulence columns or votex sheet (accompanying drawing 1 is to be provided with turbulence columns in vertical paper direction) are set in Duan, are used for strengthening air-flow by being somebody's turn to do
Less turbulence during section, thus increase the collision probability between charged particle, improve coalescence efficiency.Bipolar charge-turbulent flow coalescence
The Basic Mechanism of technology is conveying and the mixing that bipolar charge granule realizes space large scale under turbulent flow,
The collision of Kolmogorov yardstick, coalescence, and granule coalescence is played facilitation in short distance by Coulomb force.Intergranular coulomb
Power is the key that bipolar charge-turbulent flow coagulating technique has greater efficiency to the facilitation of turbulent flow coalescence.If cyclonic separation mistake
Journey exists turbulent flow coalescence effect, then bipolar charge device is set at cyclone inlet to bipolar electric on granule lotus
Lotus, just can utilize the intergranular Coulomb force of bipolar charge to strengthen the efficiency of cyclonic separation fine particle.The research of Hou Guangxin etc.
Show cyclone separator exists stronger turbulent flow coalescence effect.
Being inspired by the studies above, this project proposes to use bipolar charge technology before cyclone separator, makes fume duct fly ash
Bipolar charge distribution on lotus, enters back into and carries out coalescence, separation in whirlwind field, can strengthen the arresting efficiency of fine particle.
