Detailed description of the invention
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, aobvious
So, described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based in the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all
Belong to the scope of protection of the invention.
Embodiment 1
In the embodiment of the present invention, impact returning charge formula flue reactor, including smoke inlet section 1, mixing reactor 2, circulation
Revert system 3, impingement separator 4, impact baffle plate 5 and exhanst gas outlet section 7, smoke inlet section 1 is arranged on mixing reactor
The lower section of 2, the upper end of mixing reactor 2 connects impingement separator 4 and enters the lower end of impingement separator 4, and impact separates
The internally installed impact baffle plate 5 of device 4, spout and impact baffle plate 5 within impingement separator 4 are consumable accessorys, use and assemble
Mode is installed, and the opened above of impingement separator 4 has manhole 6, for the maintenance of consumable accessory is changed, and can be by inspection
Repair hole 6 the structure entirety such as impact baffle plate 5 hang out maintenance or changes.The side of impingement separator 4 is provided with exhanst gas outlet section
7, and exhanst gas outlet section 7 is above impact baffle plate 5；One end of circulation revert system 3 connects the lower section of impingement separator 4,
The other end connects the side below mixing reactor 2 and connects.The medicine such as calcium hydroxide or sodium bicarbonate it is provided with on mixing reactor 2
The entrance of agent powder and the entrance etc. of circulation revert system 3, flue gas and medicament hybrid reaction in mixing reactor 2,
And separate in impingement separator 4, tiny powder enters sack cleaner, bulky grain with flue gas by exhanst gas outlet section 7
Solia particle under effect of inertia, separate return, continue to participate in reaction.
The impact returning charge formula flue reactor that the present invention provides, it is with the flue before sack cleaner entrance as body junction
Structure, a kind of forms new reactor by what structure changed.Ultra-fine pharmacy response powder sprays into cigarette by mixing reactor 2
After road, it is sufficiently mixed with flue gas, collides and reacts, in the relevant position of flue, be provided with mixing reactor 2, flue gas
Here speed change, turbulent flow and impact suddenly, carries out impact dispersion, the solia particle in flue gas for the solia particle in flue gas
Predominantly dust, medicament and response derivative, this physical impact, the beneficially disengaging of medicament surface reaction product
With crushing of pharmacy particle, it is achieved the refreshing of medicament microparticle surfaces, the particle after strengthening flue gas and refreshing contacts, and adds further
Strong reaction effect.Separating in impingement separator 4, tiny powder enters sack cleaner with flue gas, and oarse-grained solid is micro-
Grain separates under effect of inertia and returns, and continues to participate in reaction, and circulation returning charge amount is controlled by powder flow valve etc..It practice,
When, behind the material position in impingement separator 4 to certain level, impact separation effect weakens, and the effect of flue gas draw dust will increase
By force, whole process is the control process of a dynamic equilibrium, and this is also the basis that the present invention can realize reliably working,
Guarantee that system does not haves Infinite Cyclic and uncontrollable operating mode occurs.
The present invention is arranged on before sack cleaner, and more situation is, be connected to smoke cooling tower and sack cleaner it
Between, become the main equipment of flue gas desulfurization depickling together with sack cleaner.It may be used for the technique with calcium hydroxide as medicament
