Description
Technical field
The present invention relates to a kind of production technology of calcium hydroxide, particularly a kind of can realize to continue production calcium hydroxide
Process, and for continuing the production line of production calcium hydroxide.
Background technology
Calcium hydroxide can be widely applied to the row such as water process, leather industry, papermaking, Industrial Boiler, desulfurization, depickling, chemical building material
Industry, application is quite varied, and usage amount is also very huge, therefore the production to calcium hydroxide proposes higher requirement.Hydrogen
The production of calcium oxide is by traditional original lime slaking technology epoch, when having been converted to carry out quantity-produced by production equipment
Generation, and multiple lead-times are experienced, this is due to caused by the change of lime deep process.Earliest, using simple and crude
Artificial digestion technique, yield poorly, quality of finished is poor, can only meet the needs of low-end market, with the development of processing technology, goes out
Show lime under agitation equipment, water can have been added to be stirred digestion lime in equipment, it is a kind of progressive at last, but due to equipment
Belong to the early production in the field, various aspects of performance index is very low, and efficiency is very low.Furthermore the lime for specialty afterwards, occur disappears
Change equipment, lime slaking equipment is primarily referred to as lime slaking machine, is also ashing melting machine, lime slaker, limeslaker etc., it is
By quick lime（Calcium oxide）It is digested to the special equipment of milk of lime or slaked lime powder.One-level limeslaker is occurred that first,
The technique for making lime be processed into white lime has leaping for matter, and very big improves production efficiency, has driven the development of industry.
But with the high speed development in this several years markets, product dosage and the lifting using quality requirements, according to old reason
The calcium powder industry of high speed development can not have been met by reading the old-fashioned one-level digester of design, develop the multistage digestion of lime therewith
Device.
Lime multistage digester has lot of advantages compared to past old process equipment：General device can use two-stage or
Three-level digestion process, lime slaking rate is greatly improved, the quality of product is also lifted therewith, can reach 20 tons per hour at present
（Old equipment only has 4 tons or so of yield）, and advanced PLC automation control systems are combined with, greatly reduce artificial strong
Degree, the centralization of equipment manipulation is not only increased using automation, improve the controllability of equipment production process, and to carrying
The quality of high product also favourable one side, and be equipped with calcium powder production special dust seperator, and internal negative pressure gather dust work
Skill, effectively reduces the dust discharge amount in production process, and the produce reality situation of calcium powder is taken on a new look significantly.
But there is following defect in all calcium hydroxide equipment used at present：1）Traditional approach：Calcium hydroxide block is direct
Outdoor plus water, digestion reaction is completed, and sold；Problem be present：Environmental pollution greatly, worker is caused dust injury,
The calcium hydroxide water content produced can not ensure, finish fineness can not ensure, finished product calcium content can not ensure, the production cycle
Length, recruitment are more（Substantially such a mode is eliminated）.2）" grey calcium machine " mode：Calcium oxide plus water are reacted, add in grey calcium machine
Row is ground, by grinding as finished product, can not be discharged by grinding as slag；Problem be present：Add water ring section pollution environment same
Sample is serious, high energy consumption when being ground with grey calcium machine, part " raw burn ", " impurity " can be ground when grinding after be mixed into finished product and reduce into
Product calcium content, yield is limited to plus water reaction time and place, water content are uncontrollable.3）Old-fashioned dry method mode：Material is broken
3~6mm feed and then feedwater are broken to, digests and is completed by special digestion reaction bin equipment, select powder afterwards, by impurity when selecting powder
Discharge, and installed dedusting additional on whole system, to ensure production environment.But there is problem in above method：First, production is set
Complicated, cost height is put, price is high, improves cost of investment；Second, high energy consumption, it is impossible to make full use of waste heat to improve reaction speed
Degree；Third, production efficiency is relatively low.
The content of the invention
The present invention is primarily directed to production capacity existing for existing calcium hydroxide production device is low, efficiency is low, easily pollutes environment
The problems such as, it is an object of the invention to provide a kind of energy-conservation, efficient calcium hydroxide to continue production technology and special production line.

Product is sent into dust fall in storage tank 13 by drainage conduit 15 into dust-like and accumulated, and the air in storage tank 13 is again through being located at storage tank 13
Top set be attached thereto logical backwind tube 14 through air blower 12 be sent into grinding machine 10 in, formed air containment loop, form
Product are sent in storage tank 13, and the finished product of aggregation is discharged by the discharge port 22 for being arranged on the bottom of storage tank 13 in storage tank 13.
Enter heat conversion system after the hot-air removing dust device dedusting of the discharge of collection device 16 of drying of the present invention, by heat
The spray water source of spray system is passed to, makes shower water that there is higher temperature, then one-level is digested and enters spray, to improve spray
Efficiency.
Coarse fodder in the separator 11 of the present invention is dropped in grinding machine 10 because that can not be blown into storage tank 13, right by grinding machine 10
Powder is formed after thicker material grinding, is sent to again by air blower 12 in separator 11, after being sorted again, will be conformed to
The finished product asked is sent into storage tank 13, and thicker material falls into grinding machine 10 and is ground again, so repeatedly, to what can not be ground
