Description
Technical field
The utility model is related to a kind of high effective desulphurization device, belongs to flue gases purification field.
Technical background
Domestic coal-burning boiler uses wet fuel gas desulfurizing technology mostly, by the desulfurizing agent of alkalescence by nozzle/packing layer point
After dissipating, counter current contacting reacts in absorption tower with flue gas, reaches SO in removing flue gas2Purpose, the big multipotency of desulfuration efficiency
Reach 90% or even 95%.As China's standard limit of smog release is gradually strict and the currently proposition of " ultra-clean " discharge theory, coal-fired electricity
Requirement of the factory to desulfurizer operational efficiency is also improved constantly, particularly the power plant user of burning high sulfur coal, and its desulfuration efficiency is needed
Reach more than 99%.
Current portions power plant improves desulfuration efficiency using double tower Two-way Cycle technology, but the technology exist equipment investment it is high,
The problems such as floor space is big, the flue gas high-efficiency desulfurization that lower cost how is realized under conditions of land limited is urgently to solve at present
One of problem certainly.
Utility model content
The utility model is related to a kind of high effective desulphurization device, and described device is by outer tower body, middle tower body, interior tower body, tower top
Portion, interior spraying layer, outer spraying layer and demister composition；
Described outer tower body sidewall is connected with smoke inlet, and the top of outer tower body sidewall forms with top of tower and is tightly connected.
Described inter-chamber tower body is located between outer tower body and interior tower body, highly less than outer tower, open top.
Described interior tower body is located at portion in inter-chamber tower body, top and tower top are formed and be tightly connected, and bottom opening and is higher than
Between tower body bottom.
If the outer spraying layer of dried layer and demister are provided between outer tower body and middle tower body, for the thick desulfurization of flue gas.
If spraying layer and demister in dried layer are provided with inside interior tower body, for the fine de-sulfur of flue gas.
In using above-mentioned high effective desulphurization device, after fresh desulfurization slurry is mixed with interior pond slurries, formation mixed liquor is delivered to
Spraying layer, now plasm PH value is higher, to low concentration SO2Assimilation effect it is strong；
Spray rear slurry falls to middle tower body bottom Nei Chi, forms interior pond slurries, interior pond slurries part interior circulation
Pump is transmitted back to interior spraying layer, and another part is delivered to outer spraying layer and mixes with outer circulation slurries；Now slurries not yet react complete,
To the high concentration SO in flue gas2Assimilation effect is still preferable；Spray rear slurry falls to outer tower body bottom Wai Chi, outside a part
Circulating pump is transmitted back to outer spraying layer and forms outer circulation slurries, and another part is expelled directly out as waste water.
The utility model is related to a kind of high effective desulphurization device and technique, and its operation principle is：Flue gas enters from outer tower body side
Enter, under the stop of middle tower body and the drag effect of top spraying layer, flue gas is in outer tower body and the annular region of middle tower body
Inside it is uniformly distributed and flows up, chemically reacted with the desulfurization slurry for spraying, completes thick sweetening process；After thick desulfurization
Flue gas reaches outer top of tower by demister, then is redirected back into interior tower from top, along the gap between middle tower body and interior tower body
Flow downward；Flue gas is changed direction after tower bottom again in reaching under the stop of slurry pool liquid level, into interior tower body in upwards
Flowing, and fine de-sulfur process is completed in the presence of interior spraying layer slurries；Flue gas leaves desulfurization and fills by demister after fine de-sulfur
Put.
Compared with the prior art, a kind of high effective desulphurization device of the present utility model and technique have advantages below：
（1）By way of inside and outside tower, the counter current contacting process twice of flue gas and desulfurization slurry is formd, it is double with double tower to follow
Loop technique compares the floor space and cost of investment for reducing desulphurization plant；
（2）Efficiently utilized by the classification of desulfurization slurry, reduce the operating cost of desulfurizing tower.

Specific embodiment
To make the utility model apparent understandable, 1 respectively from two sides of serum recycle and flow of flue gas below in conjunction with the accompanying drawings
Face is described in detail.
Serum recycle：Fresh desulfurization slurry is delivered to interior spraying layer with interior circulation slurries, and now plasm PH value is higher, to low
Concentration SO2Assimilation effect it is strong.Spray rear slurry falls to pond 8 in middle tower body bottom, and part circulating pump is transmitted back to interior
Spraying layer forms interior circulation slurries, and another part is delivered to outer spraying layer and mixes with outer circulation slurries.Now slurries not yet react
Completely, to the high concentration SO in flue gas2Assimilation effect is still preferable.Spray rear slurry falls to pond 9 outside outer tower body bottom, one
Divide and be transmitted back to outer spraying layer formation outer circulation slurries with circulating pump, another part directly leads out.Interior pond 8 does not connect with outer pond 9.
Flow of flue gas：Flue gas enters from outer tower body side, stop and the drag effect of top spraying layer in middle tower body
Under, flue gas is uniformly distributed and flows up in annular region of the outer tower body with middle tower body, with the desulfurization slurry for spraying
Chemically react, complete thick sweetening process, desulfuration efficiency is not less than 90%；Thick flue gas after desulfurization reaches outer tower by demister
Top, then interior tower is redirected back into from top, the gap along between middle tower body and interior tower body flows downward；Flue gas reaches interior bottom of towe
Changed direction again under the stop of slurry pool liquid level behind portion, into interior tower body and flowed up, in the work of interior spraying layer slurries
Fine de-sulfur process is completed with lower, desulfuration efficiency is not less than 90%；Flue gas leaves desulfurizer by demister after fine de-sulfur.
By above-mentioned high effective desulphurization device and serum recycle technique, the desulfurization slurry for realizing PH high absorbs low SO2Concentration
SO high is reabsorbed after flue gas, slurries PH reductions2The substep sweetening process of concentration flue gas, total desulfuration efficiency is up to more than 99%.
