Abstract
The present invention relates to a production method for solid seawater. After the solid seawater is diluted, the solid seawater can be used for transportation, temporary culture, the cultivation of marine animals and plants, the building of artificial seawater bathing fields, etc. Steps comprise that a) sodium chloride is crystallized out after led seawater or underground brine are concentrated; b) the bitter halogen generated after the sodium chloride is crystallized out is naturally refrigerated in winter to crystallize a sodium sulfate mixed salt; c) the residual bitter halogen generated after the sodium sulfate mixed salt is crystallized out is further concentrated in a halogen storage tank, and then decocted into solid to obtain a bitter halogen mixed salt; d) the component and the content which are obtained by testing and analyzing three steps are pulverized and prepared into finished solid seawater according to the component content of the seawater. Because a bitter halogen resource generated after the salt is made is used, the production cost is largely reduced. A very favourable condition is created for the development of artificial seawater, the resource is recovered, and coastal society and ecological environment are protected.
Description
Technical field
The present invention relates to a kind of production method of solid seawater, can be used for transporting, support temporarily and culture marine animal and plant after the dilution of solid seawater and build artificial seawater outdoor bathing place etc.
Background technology
People's raising and breed marine animal and plant need seawater.Obtaining seawater can have two kinds of methods, and the one, directly from the ocean, obtain; The 2nd, with obtaining simulated seawater behind the made solid chemical material dilute with water.Chinese patent 93107655.2 discloses a kind of " synthetic sea water ", adopts the number of chemical material formulated according to the ratio in natural sea-water; Chinese patent 98110523.8 disclosed " seawater element " also is to adopt the number of chemical material formulated according to the ratio in natural sea-water; These two kinds methods of producing the solid seawater all are to finish on the basis of analyzing seawater component, the production cost height, and the trace element loss is big.Chinese patent 95100408.5 discloses a kind of " natural sea-water extract and manufacture method thereof ", this method forms through two-step microbial processing, condensing crystal with natural sea-water, add potassium alum at last again as scavenging agent, kept the nearly all composition in the seawater, low production cost, but the production cycle is long, can't accurately control the ratio of various main components.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of seawater of solid cheaply, and can simulate the seawater of different areas as required.
The production method of solid seawater of the present invention comprises the steps:
A) draw the concentrated post crystallization of seawater or subsurface brine and go out sodium-chlor;
B) with the bittern after above-mentioned the evaporating brine, carry out naturally frozen the winter that is lower than-5 ℃ in temperature, and crystallization goes out the sodium sulphate mixing salt;
C) above-mentioned crystallization is gone out be brewed into solid after residue bittern after the sodium sulphate mixing salt further concentrates in halogen storage pool, obtain the bittern mixing salt;
D) sodium-chlor that obtains of above-mentioned three steps of check analysis, sodium sulphate mixing salt, the bittern mixing salt composition and content, pulverize, be mixed with finished product solid seawater according to the component content of seawater.
In step d), in finished product solid seawater, add sodium bicarbonate, calcium ion, magnesium ion according to assay and boiling the composition that loses in the bittern process.
In step b), that the bittern after evaporating brine is through precipitation, filtration, freezing again behind the removal impurity.
The present invention adopts the concentrated seawater way of (containing subsurface brine), produce step by step sodium-chlor, sodium sulfate mixing salt, the bittern mixing salt, and, measure the composition that loses in the concentration process by assay.Then according to each components in proportions preparation in the natural sea-water.Owing to utilized remaining bittern resource after the salt manufacturing, production cost is reduced significantly, this has not only created very advantageous conditions for the development synthetic sea water, and has reclaimed resource, has protected coastal society and ecotope.
Description of drawings
Fig. 1 is the process flow sheet of one embodiment of the present of invention.
Embodiment
As shown in Figure 1, the production method of solid seawater of the present invention comprises the steps:
A) draw the concentrated post crystallization of seawater or subsurface brine and go out sodium-chlor; Also can directly use crude salt and bittern after will evaporating brine as the raw material of next step, assay component content wherein, and carry out mark.
B) with the process of the bittern after above-mentioned the evaporating brine precipitation, filtration, remove impurity, be lower than-5 ℃ winter at natural temperature, go out the sodium sulphate mixing salt with the natural freezing method crystallization; Assay component content wherein, and carry out mark.
C) above-mentioned crystallization is gone out residue bittern further evaporation in halogen storage pool after the sodium sulphate mixing salt, be brewed into solid particulate then, obtain the bittern mixing salt;
D) analyze sodium-chlor that above-mentioned three steps obtain, sodium sulphate mixing salt, the bittern mixing salt composition and content, after the pulverizing, be mixed with finished product solid seawater according to the component content of seawater.And in finished product solid seawater, suitably add sodium bicarbonate, calcium ion, potassium ion, boric acid etc. again according to assay and boiling the composition that loses in the bittern process, make its component content more near natural sea-water.
Because each marine site concentration of seawater difference is bigger, will suitably adjust proportioning and production technique according to the difference of raw material and the requirement of commodity seawater in the production process of solid seawater, this is the known technology in marine chemical industry field, no longer repeats at this.
