Description
Technical field:
It is specifically a kind of particularly suitable the present invention relates to (PM2.5) removing sulfuldioxide of fine particle in atmosphere field
The bionical reunion dust-extraction unit of spraying vibrating compound that fine particle (PM2.5) removes in coal-fired boiler tail gas.
Background technique:
Fine particle (PM2.5) has large specific surface area as one of the major pollutants in atmosphere, and suspension time is long,
Traditional deduster is not easy the characteristics of removing, and harm to the human body is bigger.Some scholars are studying by particle both at home and abroad at present
Object pretreatment first allows fine particle reunion to be grown up, and the method for traditional deduster removing is recycled to control the fine grained in atmosphere
Object pollution.
Agglomeration techniques generally have acoustic agglomeration, magnetic coagulation, and electricity is reunited, chemical agglomeration, and steam phase transforming is reunited etc., pass through reunion
Technology can make fine grained be changed into coarse granule, can remove carefully using with the traditional deduster high to coarse granule eliminating efficiency
Microparticle, therefore agglomeration techniques are the important technicals for controlling fine particle (PM2.5) in air.In air fine particle it
Between generally there are interaction forces such as Coulomb force, Van der Waals force, liquid bridge power, it is thin that sound wave can promote the collision between particle to promote
Particulate matter is reunited, therefore it is a kind of vibration reunion that acoustic agglomeration is practical.But since in acoustic agglomeration there is damage in conversion process of energy
It loses, decaying of the sound wave in dust-contained airflow is very big, so the energy consumption of acoustic agglomeration is very high always.Many patents have been focused into drop
Low reunion energy consumption, in terms of improving agglomeration efficiency, Chinese patent CNI00531862C devises a kind of based on sound wave and additional seed
Particle synergy removes fine grain device and method, although this method is conducive to improve fine grain removal efficiency, but by
It is added in solid seed grain difficult, it is difficult to it is dispersed in air-flow, affects agglomerating effect, meanwhile, it adds in the gas flow
Solid particle increases the load of dust remove of subsequent deduster again；Chinese patent CN103706219A proposes acoustic agglomeration and combines spray
Mist synergy removes the apparatus and method of fine particulates, and it is tired which solves the addition of solid seed grain to a certain extent
Difficult problem, but the energy consumption of acoustic agglomeration is still very high.Chinese patent CN104190199A proposes a kind of sound wave and phase transformation
The removing means of coupling solves the problems, such as that agglomeration efficiency is low using the synergistic effect that sound wave and phase transformation are reunited.It is above special
Benefit decays the energy loss effectively caused in air without solving the problems, such as sound wave, and according to Agglomeration Mechanism in the same direction, the above patent
The purpose for adding sound wave is to improve the reunion probability of particle to promote the mutual collision between particle.Therefore, a kind of economy is found
Mutual impacting technology is particularly significant between feasible promotion particle.
Magnetic coagulation energy consumption is higher, not only has particular/special requirement to fine particle, but also also not economic enough the conjunction from energy grade
Reason.Electricity, which is reunited, special requirement to fine grain dielectric property, while after being reunited using electricity, subsequent dust-extraction unit is generally
Electric precipitator can only be used, which has limited the applications that electricity is reunited.Chemical agglomeration and steam phase transforming reunion are relatively effective reunions
Technology, but technology consumption liquid measure is larger, it is still necessary to further study for liquids recovery and processing problem.
