It sets, and two the second through-holes 47 shift to install；4th magnet 46 is fixedly connected below transmission shaft 48, and 48 lower end of transmission shaft is connected
In 44 upper surface of spray head, and 48 surface fixing sleeve of transmission shaft is connected to impeller 49, and impeller 49 contacts the design of 43 inner wall of the second return pipe；
The spray head 44 is atomizer 44, and the contact area of clarification limewash and sulfur dioxide can be improved, prevent sulfur dioxide from reacting
It is not thorough；Connection third cavity 27 and extraneous gas outlet 5 are offered at the top of the framework 2, are equipped with pressure valve at gas outlet 5,
When air pressure restore oscillating deck 3 can not in third cavity 27, air pressure valve is opened, by the exhaust gas after rejecting sulfur dioxide and dust
Discharge, can be recycled；When work, in third cavity 27 moisture content and diluter clarification lime aqueous solution enter feed supplement
Cabin 4 rises the pressure in feed supplement cabin 4 constantly, when the pressure in feed supplement cabin 4 is greater than the magnetic force of the 4th magnet 46 and third magnet 45
When, the 4th magnet 46 moves down, and well-mixed clarification lime aqueous solution is discharged by the second through-hole 47, will drive in discharge process
Impeller 49 rotates, to make sprinkling clarification limewash in 44 rotation process of spray head, can make sulfur dioxide and clarification limewash contact
More sufficiently.
As one embodiment of the present invention, filter plate 51 is equipped with below the spray head 44；The filter plate 51 is connected
Between 2 inner wall of third partition 23 and framework, and 51 arc of filter plate is bent upwards design；The filter plate 51 is softer, elastic
Material is made, and cavity is offered in it, and cavity is interior to be filled with renewable sponge 52, and there is renewable sponge 52 patience by force, efficiently to hinder
Combustion, pulling force be good, the elastic characteristics such as big, indeformable, contains clarification limewash when initial in renewable sponge 52；When work, with
Moving left and right for three partitions 23 squeezes and loosens filter plate 51, so that the clarification lime aqueous solution in renewable sponge 52 is dripped,
Cooperate spray head 44 to spray clarification lime aqueous solution again to supplement renewable sponge 52, keeps sulfur dioxide reaction more thorough, prevent
Sulfur dioxide residue.
When work, aqueous solution enters in water pipe 15 in water tank 14, by the high-temperature heating of 11 outer wall of converter, steams moisture content
Hair forms vapor, is passed through in air inlet pipe 13 to float, the first cavity 25 is passed through together with exhaust gas, to make the ash in exhaust gas
Dirt quality increases, and precipitates dust, and as vapor and the continuous of exhaust gas are passed through, 25 air pressure of the first cavity rises, first partition
21 bendings, first through hole 211 are opened, and air pressure can be such that the dust in exhaust gas sufficiently precipitates during rising in the first cavity 25,
When the thrust that second magnet 18 is subject to is greater than the magnetic force of the second magnet 18 and the first magnet 17, the second magnet 18 is moved to right, and first is empty
The dust of 25 bottom of chamber precipitates and moisture content is entered in water tank 14 by mudhole 19, can be discharged by the second sewage draining exit 141；The
One through-hole 211 opening enters exhaust gas in aeration tube 29 by gas-guide tube 24, to be exposed by solarization air cap, with third cavity
The rising of air pressure and the accumulation of precipitating in 27, when 3 pressure of oscillating deck is greater than the torsion of torsional spring, oscillating deck 3 is to the bottom
Dynamic, expansion plate 33 is released in the effect of third spring 34, and expansion plate 33 is made to be bonded 2 side walls of framework, until entering first time
In flow tube 42, stop after contacting 42 side wall of the first return pipe, the precipitating and water generated in third cavity 27, into the first reflux
Pipe 42, the second filter screen 421 can filter sediment in the process, and moisture content enters in feed supplement cabin 4, after being mixed with white lime powder,
New clarification lime aqueous solution is formed by the filtering of the first filter screen 41, with moisture content in third cavity 27 and diluter
Clarification lime aqueous solution enters feed supplement cabin 4, constantly increase the pressure in feed supplement cabin 4, when the pressure in feed supplement cabin 4 is greater than the 4th magnetic
When the magnetic force of iron 46 and third magnet 45, the 4th magnet 46 is moved down, and well-mixed clarification lime aqueous solution passes through the second through-hole
47 discharges will drive the rotation of impeller 49 in discharge process, make water spray clarification lime aqueous solution in 44 rotation process of spray head, supplement the
The consumption of clarification lime aqueous solution in three cavitys 27, and when the bending of first partition 21, keep third partition 23 right by gas-guide tube 24
It moves, exhaust gas is passed through third cavity 27, and air pressure declines in the first cavity 25, and first partition 21 is restored, with the progress of reaction, third
The decline of air pressure in cavity 27, oscillating deck 3 are swung up, and third spring 34 compresses, and in the income of expansion plate 33 opening 32, precipitate meeting
Since the effect of gravity slides to 3 lower section of oscillating deck, can be discharged by the first sewage draining exit 35.
