Abstract
The invention discloses a treating method for extracting potassium through industrial residue straw ash. The treating method mainly includes the steps of material preparing, mixing, sediment filtering, certain thermotechnical technology water removing and the like; dry and wet straw ash can be used as the main raw material, and calcium chloride residues are used as the auxiliary material for extracting potassium materials; and residual sediment can be used for producing cement materials of building products. The treating method has the advantages that cement strength is high, concrete compatibility is good, the technology is advanced and reasonable, energy consumption is low, efficiency is high, investment is saved, cost is low, secondary pollution is avoided, and environmental protection is facilitated. According to an existing method for treating straw ash, the additional value is low, productivity is low, the dosage is small, and straw ash high in potassium content cannot be used for building products. The treating method for extracting potassium through industrial residue straw ash is a good method for thoroughly overcoming the technical defects of straw ash, eliminating a large amount of straw ash and a large number of other industrial waste residues, lowering environment pollution and facilitating environment protection.
Description
[technical field]
The present invention relates to industrial residue straw ash and extract potassium technical field, particularly relate to a kind for the treatment of process utilizing industrial residue straw ash to extract potassium.
[background technology]
From status both at home and abroad, just starting straw ash waste residue utilization in the country that the industry seventies is flourishing is the U.S., there is India subsequently, Thailand, New Zealand, Japan, the countries such as Australia have studied stalk on a small quantity for building material product, utilization ratio is about 30%, excellent straw ash entirely, a large amount of ropy ash is all stack and landfill, our country is less for the production of building material product to development research straw ash at present, only has about 3-5%, excellent thin ash entirely, other 90% ropy ashes are landfill entirely, seriously cause the secondary pollution to environment, because the maximum defect of straw ash is that water regain is large, potassium content is high at about 10-16%, add that straw ash itself is containing a large amount of amorphous Si o
2if straw ash calcining not exclusively, will change crystallization Sio into
2, he just have impact on the quality of straw ash for this reason, and in building material product, it can be the water yield increasing in building material product, potassium composition is higher, the product made can cause swelling fracture, for this reason, a large amount of use straw ash is difficult to accomplish, added value is low again, be difficult to the extensive one of the main reasons utilized, at present, stalk ash quantity is discharged every year at about 8,600 ten thousand tons by China, overall utilization is about 12%, a large amount of farmland can only be utilized to stack and landfill, meet the waste water after rainy day pouring, Liu Ru riverbed, Heisui River, severe contamination water resources, fine day is met wind one and is blown the pitch-black a slice of dust all over the sky, severe contamination atmospheric environment, so, this is that the world inscribes deeply.
Therefore, for overcoming the deficiency of above-mentioned technology and designing a kind of method that industrial residue straw ash and calcium chloride waste residue can be utilized to extract potassium product, particularly straw is utilized to generation current factory, straw, soybean stalk, cornstalk, rice straw, the waste residue of discharging after the combustion power generations such as rice husk, containing potassium composition at about 10-16%, adopt a kind of potassium product that advanced Technology is extracted, it is the method for a kind of minimizing and the harmless treatment carried out, there is a kind for the treatment of process utilizing industrial residue straw ash to extract potassium of environmental protection, contriver's problem to be solved just.
[summary of the invention]
