Description
Technical field
The utility model relates to a kind of production unit of calcium hydroxide, particularly a kind of can realize continue produce calcium hydroxide production line.
Background technology
Slaked lime can be widely used in the industries such as water treatment, leather industry, papermaking, Industrial Boiler, desulfurization, depickling, chemical building material, and range of application is very extensive, and usage quantity is also very huge, therefore has higher requirement to the production of calcium hydroxide.The production of calcium hydroxide, by traditional original lime slaking technology epoch, has changed into and has carried out the quantity-produced epoch by production unit, and experienced by multiple lead-time, and this is because the change of lime deep processing technology causes.The earliest, what adopt is simple and crude artificial digestion technique, and yield poorly, quality of finished is poor, the demand of low-end market can only be met, along with the development of complete processing, there is lime under agitation equipment, in equipment, lime can have been added water and carry out stirring digestion, a kind of progressive at last, but because equipment belongs to the early production in this field, various aspects of performance index is very low, and efficiency is very low.Moreover afterwards, occurred professional lime slaking equipment, lime slaking equipment mainly refers to lime slaking machine, and be also lime slaking machine, lime slaker, limeslaker etc., it is specific equipment unslaked lime (calcium oxide) being digested to milk of lime or slaked lime powder.What first occur is one-level limeslaker, and make the technique that lime is processed into white lime have leaping of matter, very large improves production efficiency, has driven the development of industry.
But along with the high speed development in this several years markets, the lifting that product consumption and using character require, the old-fashioned one-level digestive organ designed according to old theory can not meet the calcium powder industry of high speed development, has developed the multistage digestive organ of lime thereupon.
The multistage digestive organ of lime has lot of advantages compared to past old processing unit: general device can adopt two-stage or three grades of digestion processes, greatly improve lime slaking rate, the quality of product also promotes thereupon, can reach at present 20 tons per hour (old equipment only has the output of about 4 tons), and be combined with advanced PLC automation control system, greatly reduce artificial intensity, automatization is used to not only increase the centralization of equipment manipulation, improve the controllability of device fabrication process, and the one side also favourable to the quality improving product, and be all equipped with calcium powder to produce special dust seperator, to gather dust technique with internal negative pressure, effectively reduce the dust discharge amount in production process, the production practical situation of calcium powder are taken on a new look greatly.
But there is following defect in all calcium hydroxide equipment used at present: 1) traditional way: add water directly outdoor for calcium hydroxide block, complete digestion reaction, and sell; Existing problems: environmental pollution greatly, to workman causes dust to injure, produce calcium hydroxide water content cannot ensure, finish fineness cannot ensure, finished product calcium contents cannot ensure, the production cycle is long, recruitment many (substantially eliminating this kind of mode).2) " grey calcium machine " mode: add water calcium oxide reaction, add in ash charge calcium machine carry out grinding, by grind for finished product, cannot by discharging as slag of grinding; Existing problems: the link that adds water contaminate environment is same serious, when grinding with grey calcium machine energy consumption high, part " raw burn ", " impurity " can be mixed into finished product and reduce finished product calcium contents after grinding when grinding, output is limited to add water reaction times and place, and water content is uncontrollable.3) old-fashioned dry method mode: crush material to 3 ~ 6mm feed, then feed water, digests and is completed by special digestion reaction bin equipment, select powder afterwards, select during powder and discharged by impurity, and on whole system, installed dedusting additional, to ensure production environment.But above method all has problems: one is that production arranges complexity, cost is high, and price is high, improves cost of investment; Two is that energy consumption is high, can not make full use of waste heat to improve speed of response; Three is that production efficiency is lower.
