Sodium bisulfate is housed in the solids hopper with closed cover, is inserted into the meter after the water inlet pipe is connected inlet water solenoid valve
In measuring tank.The detection detector is by dosing pond chlorine residue data transfer to the control cabinet, when chlorine residue numerical value is greater than valve number
When value, the charging solenoid valve, the inlet water solenoid valve and the blender solenoid valve are successively opened automatically；Allot bisulfite
The liquid outlet electromagnetic valve and metering pump are automatically opened after sodium water solution, the sulfurous that will quickly prepare under the action of metering pump
Sour hydrogen sodium water solution is input in dosing pond；When detection detector detects that chlorine residue numerical value is less than or equal to valve numerical value, closing
The liquid outlet electromagnetic valve completes dosing pond dosing work.
The beneficial effects of the utility model are: both having been met by voluntarily proportion aqueous solution of sodium bisulfite to feed water by reverse osmosis
The reduction of middle chlorine residue, and reduce the production cost of directly purchase sodium hydrogensulfite titer；
The present apparatus is used to put the solids hopper setting closed cover of sodium hydrogensulfite, prevents sodium hydrogensulfite from using preceding hair
Raw oxidation reaction, increases the accuracy of aqueous solution；
Device is automatically performed the proportion and automatic liquid discharging of aqueous solution of sodium bisulfite with the setting of control cabinet valve numerical value,
Matching while using is realized in production, guarantees the accuracy of aqueous solution, while also saving the production time；
It detects detector and detection numerical value is shown by control cabinet, conveniently the variation of intuitive supervision dosing pond chlorine residue numerical value,
Device is simple, easy to operate.
