It is connected with primary cycle pond, the other end that two level conduit and two level conduit are connected with two-grade desulfurizing tower connects with secondary cycle pond
Connect；One-level conduit is provided with inclined isocon, is provided with joint on isocon, joint be connected with one-level conduit and isocon with
One-level conduit connection is provided with valve, and the end of isocon is connected with secondary cycle pond and the end of isocon is less than isocon
Joint；
The side in the primary cycle pond is separated by dividing plate with secondary cycle pond and primary cycle is communicated with dividing plate
Pond and the flowing water mouth in secondary cycle pond, the gate member being turned on and off for the controlling stream mouth of a river, institute are additionally provided with the dividing plate
Primary cycle pond is stated with being provided with agitator, liquid level gauge and pH value meter in secondary cycle pond.
Compared to prior art, the utility model has the advantages that：Can be by adjusting secondary cycle pond and one
The flow of flowing water mouth between level circulatory pool makes the liquid level in two stage cycle pond remain at secondary cycle pit level to follow than one-level
Cisterna ambiens liquid level is high, is advantageous to slurries aerating oxidation, is dehydrated the fast fast calcium sulphate dihydrate that is converted into of calcium sulfite, caused desulfurization stone
The cream crystallization water >=16%, sulfur trioxide >=36%, gypsum quality are qualified；Fraction slurries after first grade desulfurizing tower desulfurization are by dividing
Flow tube is flowed into secondary cycle pond, and after aerating oxidation and stirring, fraction slurries can also pass through secondary cycle pond and one-level
During flowing water cause for gossip between circulatory pool shows fraction slurries in two stage cycle pond and circulate, so that primary cycle pond pH：5-
5.5, secondary cycle pond pH：6-6.5, desulfurized effect obtain stabilization.
