Description
Technical field
This utility model is specifically related to a kind of sodium pyrosulfite Wet-method production device.
Background technology
Sodium pyrosulfite is white or slightly yellow crystalline powder, is dissolved in water and glycerol, is slightly soluble in ethanol, insoluble in benzene class. Its solubility with temperature in water raises and increases, and generates stable sodium sulfite after being dissolved in water, makes moist and easily decomposes, and dew is empty in gas and easily slowly aoxidizes and release SO2, finally absorbs oxygen and is oxidized to Na2SO4; Contact releasing SO2 with strong acid, and generate corresponding salt; Sodium sulfite is generated with Caustic soda or soda ash solution when reacting; Addition product can be generated with aldehydes.
Traditional process units cost is high, and efficiency is low, and vent gas treatment is not thorough, brings much unnecessary trouble to using.

Scrubbing tower connects the 3rd reactor.
Pneumatic conveyer dryer internal temperature is stable at 160 DEG C.
Operation principle: first by sulfur crushing powdering, combustion furnace is sent into compression air, spontaneous combustion is carried out in 600��800 DEG C, air addition is about 2 times of theoretical amount, gas SO2 concentration is 10%��13%, remove Sublimed Sulfur and other impurity after cooled dedusting and filtration, and reduce gas temperature to about 50 DEG C, pass in tandem reactor. It is slowly added to be neutralized reaction with the soda ash solution of mother solution and water dissolution at third level reactor, the sodium sulfite suspension generated passes sequentially through the second level, first order reactor, absorption reaction is carried out with SO2, generate sodium pyrosulfite crystallization, reaction is exothermic reaction, for keeping optimum condition, general control exists
About 45 DEG C. The magma discharged from first order reactor is routed directly to centrifuge. Mother solution after separation returns choline device. Wet sodium pyrosulfite is supplied gas flash dryer, is finished product at 160 DEG C after drying. From tail gas emptying after tail gas tower alkali liquor absorption that third level reactor is discharged.
