Grey matter circulating purification system.
Background technology
The industrial furnace smoke of the industries such as building materials, thermal power generation, steel, nonferrous smelting has the spy that temperature is high, concentration is high
Point, contain substantial amounts of flue dust and sulfide in the flue gas discharged, seriously pollute air, and influence human health, especially cigarette
Diameter is less than or equal to PM2.5 particles in gas, because its specific surface area is big, can adsorb a variety of poisonous and harmful substances, in an atmosphere stagnant
Stay the time to grow, long transmission distance and lung and the bronchus for being easily accessible human body, respiratory function can be damaged, cause inflammation, asthma
Etc. respiratory disease, make cardiopathic illness rate and death rate increase, and there is potential carcinogenicity.Therefore, human body is good for
Health and atmosphere quality have a great influence.And China is the country using coal as main energy sources, coal combustion generates a large amount of sulphur oxygen
Compound, oxysulfide can also be converted into PM2.5 and cause haze weather, and strong influence occurs in the trip to people, so
PM2.5 improvement is extremely urgent.
According to statistics, traditional cleaner, such as electrostatic precipitator, sack cleaner have very high to the particle more than 10 μm
Efficiency of dust collection, general up to more than 99%, however, being gradually reduced with particle diameter, efficiency of dust collection is gradually lowered, about
The flying dust for having 1% enters air, forms the major part of atmospheric aerosol.This part flying dust is less than 2.5 microns even with particle diameter
Based on Submicro particles, its quantity can reach flying dust sum more than 90%, and surface be often enriched with it is micro heavy in coal
Metallic element and organic pollution, it is very harmful.In extreme circumstances, efficiency of dust collection can even be less than 50%, using coalescence skill
Art strengthens a new developing direction for being collected into dedusting technology for fine particle.Particle coagulation technology and removing equipment can
Improve the efficiency of dust collection of cleaner；The discharge of PM2.5 and toxic heavy metal is substantially reduced, mitigates the people caused by Particulate Emission
Body endangers, and improves atmospheric visibility, and operating cost is relatively low, reliable, safeguards that less, adaptability waits well point.Therefore to me
The environmental improvement of state is significant.
At present, the device species both at home and abroad for the gas cleaning processing of industrial coal, oil burning boiler is various, mainly includes
Dry type and wet type.And current Wet smoke purified treatment cost is higher, resource utilization is relatively low, is extremely difficult to sustainable development
Requirement.
