Description
Technical field
The present invention relates to a kind of characteristic of utilizing the electron-defect compound of boron, produce the equipment that boron content is high, dissolve four water eight Sodium Tetraboratees fast, solvent temperature is low, belong to chemical industry preparing technical field.
Background technology
At present; the material that occurring in nature boron-containing quantity is the highest is borax; but borax is water-soluble low, meanwhile, be at 70 ℃; can dissolve; after temperature reduces, boron is crystallization once more, and dissolution time is long; like this, be unfavorable for the application of wood protection, water treatment, soap/surfactant, industry and fertilizer trade.Domestic use be i.e. four water eight Sodium Tetraboratees of the happy boron of imported from America speed substantially, domestic do not have a large-scale production.Jiangsu clay fertilizer institute and Anhui clay fertilizer borax used, boric acid and water mix now, the dissolving of heating, reaction, and a kind of instant four water eight Sodium Tetraboratees of production are main polymerized boric fertilizer, it is produced in aqua will add promoting agent.Meanwhile, the special-purpose drying equipment of themselves design of Anhui clay fertilizer Dryly use.
But in above-mentioned prior art, there is following defect: what the first, it was produced is instant boric fertilizer; need various additives and promoting agent; product purity is low, can not, for industries such as wood protection, water treatment, soap/surfactant, industry, only limit to fertilizer industry.The second, its making method can not serialization, mass-producing, industrialization.Three, its drying plant is specific equipment.
Summary of the invention
The object of the invention is to utilize general drying plant and reactor, automatically control, produce continuously, do not add any other reagent, a kind of equipment that at low temperatures can rapidly-soluble four water eight Sodium Tetraboratees, this equipment has been filled up the blank that domestic industry is produced four water eight Sodium Tetraboratees.
The object of the invention is to realize in the following way: first in reactor, by chemical ratios, add borax, boric acid and water, then reacting by heating still, allow borax, boric acid carry out abundant polycondensation and form mixed liquor, with charging pump, mixed liquor is delivered in drying plant, in this drying plant, with the utmost point short period of time, mixed liquor is dried as Powdered four water eight Sodium Tetraborate finished products.
The equipment of above-mentioned production four water eight Sodium Tetraboratees, the thermal source of its heated drying air can be the various ways such as steam, electricity, gas furnace, oil oven and coal furnace.
The equipment of above-mentioned production four water eight Sodium Tetraboratees, its drying plant is Highspeedcentrifugingandsprayingdrier, the device of this Highspeedcentrifugingandsprayingdrier and recovery finished product is the general-purpose equipment of drying plant factory.
The equipment of above-mentioned production four water eight Sodium Tetraboratees, its reactor can be a plurality of.
The equipment of above-mentioned production four water eight Sodium Tetraboratees, its reaction is continuously, circulation, has realized cleaner production.
The equipment of above-mentioned production four water eight Sodium Tetraboratees, its packing is full-automatic or semi-automatic pack-thread, output also can adopt manual packing less.
The present invention adopts automatic control, serialization, large-scale production, has reduced production cost, has saved manpower, produces a kind of production unit of pure single product, fills up the blank that domestic industryization is produced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
