Description
Technical field
The present invention relates to a kind of high-purity Si O
2Production technology, particularly a kind of rotary type self-resistance heating pickling still.
Background technology
Get into 21 century, global microelectronics industry, photovoltaic industry are flourish, to high-purity Si O
2The product demand amount grows with each passing day, and has reached nearly ten-million-ton scale at present.According to measuring and calculating, one ton of SiO of every processing
2Refined ore produces the acid-bearing wastewater about 10 tons approximately, like the high-purity Si O with 5,000,000 tons of the annual processing of China
2Raw material and product calculate, and promptly meaning has 5,000 ten thousand tons acid-bearing wastewater approximately with producing, and as not handling, certainly will enter rivers, and this will cause very big pollution to environment undoubtedly.
The present situation of China is at present: the SiO2 processing industry overwhelming majority intersperses among villages and towns in rural areas, and technology falls behind, cruelty is operated, be simply equipped, the sour water crossing current has been undisputable fact everywhere.No matter be SiO2 raw ore or particle or powder through processing, adding sour removal of impurities all is one crucial process procedure.Conscientious this process of saying is also lived at the mercy of the elements.Because this traditional chemical reaction process under the normal temperature state of nature, on average needs about 30 days time, if reach possibly more than 90 days in the winter time, so its production efficiency is very low.
Domestic existing minority unit is attempting feeding steam in the acidleach process and is heating, and this certainly will newly constructed boiler.Although increased investment, steam cools off easily, and water of condensation has diluted acid solution, so also just reduced the effect of acidleach, is to lose more than gain, and most still more medium-sized and small enterprises also hold can't stand this heavy burden economically.In fact, this way is helpless to the minimizing and the processing of acid-bearing wastewater at all.
In sum; The static acid leaching process of traditional normal temperature, efficient is low, acid consumption is big, water loss is big, workman's work load is big, and environmental pollution is serious; Be the persistent ailment of present domestic SiO2 industrial community, similarly also there is this drawback that needs to be resolved hurrily in processing minerals certainly.
Summary of the invention
The technical problem that the present invention will solve is the deficiency to prior art, has proposed the rotary type self-resistance heating pickling still of a kind of pickling reaction efficiency height, good impurity removing effect.
The technical problem that the present invention will solve realizes that through following technical scheme a kind of rotary type self-resistance heating pickling still is characterized in: be provided with the high-resistance alloy kettle; Kettle has thermal insulation layer outward, and the kettle two ends are contained on the still seat through the rotating shaft of concentric setting, and wherein an end rotating shaft is joined through the step-down gear of shaft coupling and driven by motor; Top longitudinally along kettle is provided with the material mouth, and renovate a material mouthful top, and a side of renovating is a locking mechanism; With the material mouthful over against autoclave body bottom be provided with venting port, exhaust ports is equipped with exhaust solenoid valve, in the rotating shaft of kettle, radially be provided with two the cover brushes; Be respectively control brush and heating brush; Kettle joins through heating brush and big electric current step-down transformer, and exhaust solenoid valve joins through control brush and transformer, on the line between control brush and the transformer, is connected with limit switch; Limit switch is arranged on the still seat, is provided with the instruction triggers plate that cooperates with limit switch in a side of shaft coupling.
The technical problem that the present invention will solve can also further realize through following technical scheme; Exhaust solenoid valve is provided with valve body and valve seat, in centre air inlet port is arranged, and venting hole is arranged on valve body; Valve body is provided with the valve plug of taking back a spring, and valve plug and electromagnet armature join.
The present invention compared with prior art; Rotary type self-resistance heating pickling still is a kind of dynamic reaction unit; And kettle be under the about 50 ℃ of left and right sides states of constant temperature the operation, so can the time of chemical reaction be shortened in 4 hours, improved nearly 200 times of working efficiency than traditional technology; Kettle can be done the two way alternate operation, SiO2 particle phase mutual friction aggravation, and this has improved impurity-eliminating effect greatly, and is very favourable to improving product purity; Reduced the usage quantity of acid and water significantly; Reduced the quantity discharged of acid-bearing wastewater and acid mist significantly, simultaneously, discharged because this tooling can adopt to concentrate to the acid-bearing wastewater of a small amount of discharging and acid mist, so help the protection of ecotope.
