Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
As it is shown in figure 1, the flue gas desulfurization device of the present invention includes housing 1, air inlet pipe 3, escape pipe 11, overflow launder 6, overflow
Plate 7, liquid supplementation pipe 5, rotate dividing plate 8, floating drum 9, cant beam 10, feed tube 16, drain pipe 17, feed tube control valve 18,
Drain pipe control valve 19, rotation dividing plate contact 20, overflow plate contact 21, demister 12, fan blade 15, motor 23, control
Device 22 processed.Wherein air inlet pipe 3 is entered by the upper end of housing 1 side, and air inlet pipe 3 downwardly extends, the air inlet of air inlet pipe 3 lower end
Liquid level is pressed close in pipe outlet 4, and absorbing liquid is sodium hydroxide solution, is arranged over multiple overflow launder 6, multiple overflow launders 6 in housing
Being set up in parallel, overflow launder 6 is provided with liquid supplementation pipe 5, and liquid supplementation pipe 5 is connected with housing 1 bottom with liquid pump by pipeline, Mei Geyi
The return side connection being positioned at overflow launder below chute 6 has overflow plate 7, overflow plate 7 to downwardly extend along the vertical direction of housing,
Each overflow plate 7 is provided with rotation dividing plate 8 near escape pipe 11 side, and rotating dividing plate 8 can rotate around a cant beam 10,
Rotate dividing plate 8 top and have a kink, rotate the lower partition and connect and have floating drum 9, floating drum 9 to float on liquid level, rotate dividing plate and
The material of floating drum is politef, rotates and has flow of flue gas path, overflow plate between kink and the overflow plate 7 of dividing plate 8
The bottom of 7 also has flow of flue gas path with between rotation dividing plate 8, and escape pipe 11 is positioned at the opposite side of housing, escape pipe import
13 press close to liquid level, and escape pipe 11 upwardly extends through housing, and escape pipe outlet is provided with fan blade 15, and fan blade 15 is by electricity
Machine 23 drives and rotates, and is provided with feed tube 16 in the middle part of housing 1, and housing bottom is inclined ramp, by air inlet pipe 3 direction to giving vent to anger
Pipe 11 direction tilts, and housing bottom is positioned at escape pipe 11 side and is close to housing bottom and is provided with drain pipe 17, and housing bottom can be pacified
Inferior sulfate radical, to be passed through oxygen, is oxidized to sulfate radical by dress oxygen channel.Controller 22 is with feed tube control valve 18, drain pipe
Control valve 19, rotation dividing plate contact 20, overflow plate contact 21 are connected.
Flue gas is entered by air inlet pipe import 2, flows downward along air inlet pipe.Liquid level is pressed close in air inlet pipe outlet, and flue gas is from air inlet pipe
The harmful substance absorbed liquid such as outlet ejection, sprays to liquid level, and flue gas carries out contacting for the first time with liquid level, sulfur dioxide in flue gas are inhaled
Receive.The bottom of flue gas flow direction overflow plate is with the flow of flue gas path rotated between dividing plate subsequently, and liquid supplementation pipe is constantly in overflow launder
Pouring into absorbing liquid, the absorbing liquid that overflow launder constantly overflows flows out from the return side of overflow launder, flows downward in overflow along overflow plate
Overflow plate is left in the bottom of plate, forms absorbing liquid curtain, and flue gas, by this absorbing liquid curtain, is further purified.Flue gas subsequently
Flow through the smoke flow channels between the kink and the overflow plate that rotate dividing plate, flow to the bottom of next overflow plate with rotating dividing plate
Between flow of flue gas path.Multiple overflow launders arranged side by side, overflow plate, rotation dividing plate constitute continuous print, tortuous flue gas stream
Road all.Flue gas has reached discharge standard through the purification of multiple absorbing liquid curtains.
After flue gas leaves the smoke flow channels between last kink and overflow plate rotating dividing plate, flow downward and enter out
Tracheal entrance.Liquid level is pressed close in escape pipe import, and under the effect of suction of giving vent to anger, absorbing liquid is inhaled into escape pipe import, hits subsequently
Hitting on liquid barrier 14, under the effect of liquid barrier, liquid strikes the inwall of escape pipe and is then out escape pipe.Suck and clash into
Process create multiple tracks absorbing liquid curtain and absorb liquid mist, flue gas is through this absorbing liquid curtain and absorbs liquid mist and has obtained further clean
Change.Flue gas after purification removes moisture removal by demister 12, leaves escape pipe discharge under the drive of fan blade 15.
In running, if needing to regulate the treating capacity of flue gas, absorbing liquid, the liquid level of rising can be added in desulfurizer
Promotion floating drum moves upward, and then the bottom of overflow plate diminishes with the flow of flue gas path rotated between dividing plate, owing to arranged side by side is overflow
The bottom of stream plate all diminishes with the flow of flue gas path rotated between dividing plate, it is possible to control the amount of flow of flue gas.On the contrary,
If needing to increase the circulation of flue gas, drain pipe can be controlled and discharge appropriate absorbing liquid, thus increasing flow of flue gas path
Cross-sectional area.
Further, it is also possible to controlled the height of liquid level by controller, when liquid level is too high, floating drum drives rotation dividing plate to move upward,
When moving to a certain degree, rotating dividing plate and can strike the overflow plate contact 21 of overflow plate bottom, controller receives this touching letter
After breath, control drain pipe control valve 19 and open, discharge liquid, thus reduce liquid level.When liquid lacks or discharges too much, floating
Cylinder drives rotation dividing plate to move downward, and when moving to a certain degree, the rotation dividing plate contact 20 of kink can touch on overflow plate,
After controller receives this touching information, control feed tube control valve 18 and open, fluid infusion in desulfurizer, thus improve liquid level.
From fig. 2 it can be seen that have a through hole 24 on rotation dividing plate, cant beam 10 passes from through hole 24, rotate every
Plate realizes rotating with cant beam 10 for axle.Floating drum 9 is closed barrel, for providing the power rotated needed for dividing plate rotates.
Owing to housing bottom is to tilt, the sweetening substance therefore generated and the solid impurity of absorption can under gravity to
Drain pipe position is moved, by periodic exhaustion with removal of contamination.Owing to liquid level is pressed close in the outlet of air inlet pipe, the impact of flue gas also can
Promote the impurity in liquid to move downward along inclined-plane, promote the removing of impurity.
Although describing technical scheme above in conjunction with specific embodiment, but the present invention being not limited to this embodiment,
In the case of not changing principle and the teaching of the present invention, those skilled in the art can make multiple remodeling within the scope of the invention
And modification.
