A kind of reverse spray tower of present invention offer and bubble tower series operation desulphurization system adjustment control method, Fig. 1 is reverse spray tower
With the structural schematic diagram of bubble tower series operation desulphurization system, inventive desulfurization system adjustment control method includes the following steps：
(1) it connects reverse spray tower 1 at 7 smoke inlet end of bubble tower, the reverse spray tower 1 is one or in parallel multiple；
(2) sulfur-containing smoke gas initially enters the reverse spray tower 1, and desulphurization reaction is carried out with sprayed slurry in the reverse spray tower 1,
It enters back into the bubble tower 7 and carries out desulphurization reaction, flue gas up to standard is discharged by demister 8；
The sprayed slurry is pumped out by an at least frequency conversion slurry circulating pump 5 out of the bubble tower 7, according to generating set
Payload, control the frequency of the frequency conversion slurry circulating pump 5 and/or adjust the liquid level of the bubble tower 7, to adjust desulfurization
Efficiency.
The present invention cannot meet the shape of national environmental protection minimum discharge requirement for existing bubble tower desulphurization system discharge index
Condition, substituting gas cooler using reverse spray tower 1 can using 7 concatenated high efficiency flue gas desulfurization technology of reverse spray tower 1 and bubble tower
Desulfuration efficiency is increased to 98.5% or more by the 95-97% for being bubbled tower process originally, is increasingly improved to meet country at present
Environmentally friendly minimum discharge standard requirement.
The cardinal principle of reverse spray tower 1 is that flue gas enters at the top of tower body, and sprayed slurry passes through the inverse spraying nozzle in reverse spray tower 1
It is up sprayed from tower lower part, forms certain floating level layer, the sulfur dioxide in flue gas and sprayed slurry in 1 tower of reverse spray tower
The mixing that liquidates comes into full contact with generation reactive absorption.
It is top-down, reverse spray tower into the flue gas in the gas cooler before bubble tower 7 from flue gas flow
Flue gas flow in 1 tower is also top-down, and only the slurries injection direction of the two is different.Due to gas cooler slurries with
Flue gas is fair current, therefore time of contact, and mixability is limited, and the principle of reverse spray tower 1 is then different, by reverse spray tower 1
The flue gas of interior high speed is liquidated and is mixed with the sprayed slurry fierceness of convection current, extends the hybrid reaction time in this section and increase liquid gas
Than improving the desulfuration efficiency of this section.Gas cooler mainly plays the role of cooled flue gas, and the main function of reverse spray tower 1 is
The effect of desulfurization is carried out, certainly due to needing to reach certain desulfuration efficiency, 1 sprayed slurry amount of reverse spray tower is also larger, naturally right
The cooling effect of flue gas is also more preferable.Therefore original gas cooler is substituted with reverse spray tower 1, in the condition for ensureing cooling effect
Under, local desulfuration efficiency can be more improved, bulk devulcanization efficiency is improved with this.In addition, reverse spray tower 1 be suitable for be arranged in place by
The region of limit, especially suitable for desulfurizing fly ash project.
The present invention is according to generating set load condition, by the frequency and the adjusting that control the frequency conversion slurry circulating pump 5
7 liquid level of the bubble tower adjusts desulfuration efficiency, and it is four which, which configures reverse spray tower 1, frequency conversion slurry circulating pump 5
It it is three, three frequency conversion slurry circulating pumps 5 are in parallel, and one of frequency conversion slurry circulating pump 5 is spare, the invention desulphurization system
Specifically adjustment control method is：
When the load of the generating set is less than 450MW, the running frequency of the frequency conversion slurry circulating pump 5 is adjusted to
40-48Hz, 120-200mm is adjusted to by 7 liquid level of the bubble tower, and the sprayed slurry pH value is adjusted to 4-5.3.
When the load of the generating set is 500-600MW, the running frequency of the frequency conversion slurry circulating pump 5 is adjusted
For 40-42Hz, 7 liquid level of the bubble tower is adjusted to 90-100mm, the sprayed slurry pH value is adjusted to 5.2-5.6.
When the load of the generating set is 600-630MW, the running frequency of the frequency conversion slurry circulating pump 5 is adjusted
For 38-39Hz, 7 liquid level of the bubble tower is adjusted to 80-90mm, the sprayed slurry pH value is adjusted to 5.3-5.9.
Because desulfuration efficiency is contributed more in promotion of the raising of 7 small liquid level of bubble tower than 5 frequency of frequency conversion slurry circulating pump
Obviously, therefore, under high load capacity (500-630MW) unusual service condition, 5 frequency of frequency conversion slurry circulating pump can be adjusted down, is carried
7 small liquid level of bubble tower is risen, by bubble tower 7 to the stronger absorbability of sulfur dioxide to ensure qualified discharge.
Preferably, the tower body bottom of the bubble tower 7 is equipped with slurries pipeline 4, the slurries pipeline 4 and the reverse spray tower 1
It is connected, the frequency conversion slurry circulating pump 5 is located on the slurries pipeline 4.
Preferably, slurry reflux pipe 6 is equipped between the bubble tower 7 and the reverse spray tower 1 so that reverse spray tower 1 and bubbling
Tower 7 shares the slurry pool of 7 bottom of bubble tower, and after sprayed slurry completes spray in reverse spray tower 1, slurries pass through slurry reflux pipe 6
It is back to slurry pool, recirculates and uses after being focused on to slurries in slurry pool.It is further preferred that the slurries
6 one end of return duct is located at 1 bottom of reverse spray tower, and the other end extends to the slurries of the bubble tower 7 from 1 bottom angled of the reverse spray tower
Pond.In this way, the slurries flowed out out of reverse spray tower 1 have preferable mobility in the slurry reflux pipe 6 being obliquely installed, can keep away
Exempt from deposition of the slurries in return duct to block.
Preferably, each reverse spray tower 1 accesses the smoke inlet that component selectively accesses the bubble tower 7 by selection
End.
Specifically, the selection access component includes the gas baffle 9 being located at the smoke inlet of the reverse spray tower 1, institute
It states gas baffle 9 and is opened or closed for controlling the smoke inlet of the reverse spray tower 1.It can be by controlling the gas baffle 9
Folding angle and the liquid level of the bubble tower 7 adjust desulfuration efficiency.
Specifically, the selection access component further includes entering or not entering the inverse spray for controlling the sprayed slurry
The slurries control valve 2 of tower 1.Further specifically, the slurries control valve 2 be located at for by the slurries pipeline 4 with it is described inverse
It sprays on the slurries branch pipe 3 that tower 1 connects.
Component is accessed by the way that the selection is arranged, when the reverse spray tower 1 being connected in series with the bubble tower 7 is multiple in parallel
When reverse spray tower, it can be stopped inverse by suitably closing one or more gas baffles 9 according to generating set load operating conditions
The supply of flue gas in tower 1 is sprayed, while stopping spray in one or more reverse spray towers 1 by suitably closing the slurries control valve 2
The supply of leaching slurries achievees the purpose that energy-saving to stop the operation of one or more reverse spray towers 1.
The specific implementation mode of the present invention is described in detail above in association with attached drawing, still, the present invention is not limited thereto.It is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in the protection of the present invention
Within the scope of.
