Big flue gas and spraying contact area, big flow nozzle have big and smooth circulation road.The injection installation of vortex injector 36
Direction is backwards to flow of flue gas direction, and can reduce flue gas air inducing influences it, guarantees that the shape of water curtain is complete.
The principle of the present invention is such that in deduster there are two types of the ways of contact of gas and liquid, with preparatory dispersion
It is bubbled when the water contact of (atomization or moisture film) or gas impact water curtain, to form small water droplet or water mist.When gas is close to water
When drop, since the circular air film of water droplet acts on, gas streamline will change flow direction around water droplet, and motion profile becomes bent from straight line
Line, and partial size greatly and the big grit of density then tries hard to keep original streamline and with water droplet collision, grit and water droplet shape of colliding connects
Cohesion is bulky grain after touch, and is taken away by water flow, it is clear that bigger with the contact area of dusty gas, drop diameter is smaller, water droplet
More, collision agglutination efficiency is higher；When the density of grit, partial size and relative velocity are bigger, collision agglutination efficiency is higher.
Therefore, the design of this deduster mainly increases the contact area of water and flue gas and increases the density of grit, grain
Diameter and relative velocity.
Working condition of the invention is such that flue gas is discharged into expansion chamber 20 from boiler, first passes around inlet portion 21,
Inlet portion 21 is equipped with the first water curtain water spray group 31, the second water curtain water spray group 32, at this time smoke movement fast speed, rapidly with water
Mist collision agglutination；Enlarged portion 22 is subsequently entered, the inner space of enlarged portion 22 is the largest, and the third in enlarged portion 22 is arranged in
The vortex injector 36 that water curtain water spray group 33 is installed is also at most that smoke movement speed slows down at this time, therefore increases spray
Area contacts flue gas further with water mist and achievees the purpose that remove wherein particulate matter；Last flue gas enters contraction flow region 23, receives
The water mist that the 4th water curtain water spray group 34 that contracting portion 23 is installed is formed is full of whole cross section, forms comprehensive no dead angle spray, passes through
The air-flow of contraction flow region 23 causes air velocity to be promoted because of space contraction, and the water mist sprayed by vortex injector 36 is in high-speed flow
Impact under, be further atomized into smaller droplet, and the relative velocity of gas, liquid, solid (grain dirt) three-phase is all very big, makes them
It is sufficiently mixed.So far, 90% or more soot dust granule has been removed.
