Abstract
The invention provides a preparation process for hydrochloric acid and caustic soda, which comprises sodium chloride and water. A solar battery board is used to take use of sunlight for generating electricity; concentration is improved by concentrating the salt in sea water through high temperature, then electrolyzation is done on the highly concentrated salt water to generate sodium hydroxide, hydrogen and chlorine, thus hydrogen chloride is generated by compounding hydrogen and chlorine, and hydrochloric acid and caustic soda are obtained at the same time. Compared with the prior art, the invention, by adopting solar to generate electricity and using sea water to make hydrochloric acid and caustic soda, which effectively reduces the cost for making hydrochloric acid and caustic soda.
Description
Technical field
The present invention relates to a kind of chemical industry technology, the sour caustic soda manufacture craft of especially a kind of acid.
Background technology
Hydrochloric acid industrial be most important acid except that sulfuric acid, be important chemical material and chemical reagent.Be widely used in aspects such as chemical industry, metallurgical industry, petroleum industry, textile industry and foodstuffs industry.As be used to make metal chloride, dyestuff and number of chemical medicine, and be used for zinc-plated, zinc-plated and porcelain enamel industry.In people's stomach, the massfraction that contains solute is 0.5% hydrochloric acid, and it can promote the digestion of food, and kill pathogens.Water absorbing hydrogen chloride gas can make hydrochloric acid.Caustic soda is widely used in all departments such as soap system, weaving, printing and dyeing, bleaching, papermaking, turpentole, metallurgy and other chemical industry.The making processes of hydrochloric acid and caustic soda is all very big to consuming, cost is high.
Summary of the invention
The present invention is directed to industrial salt manufacturing acid and the high problem of caustic soda cost, a kind of technology of preparation of hydrochloric acid and caustic soda by solar energy is provided.
To achieve these goals, the present invention takes following measure to realize:
A kind of hydrochloric acid caustic soda manufacture craft, comprise sodium-chlor, water, it is characterized in that adopting solar panel to utilize solar power generation, and with high temperature the salinity of seawater is concentrated and to improve concentration, eye water to high density carries out electrolysis then, generate sodium hydroxide, hydrogen and chlorine,, obtain hydrochloric acid and caustic soda so simultaneously making hydrogen and chlorine chemical combination generate hydrogenchloride.
Compare with present technology: the present invention adopts solar electrical energy generation, utilizes seawater manufacturing, has effectively reduced the cost of making hydrochloric acid and caustic soda.
Embodiment
The present invention has utilized natural resources fully, and it is inexhaustible not to the utmost that sun power is used, and seawater is also very cheap, thereby has reduced cost greatly.
Real case, the present invention can well utilize seawater, is fit to industrial exploitation, thereby produces hydrochloric acid and caustic soda more efficiently, will reduce more than 45% with caustic soda cost than traditional salt manufacturing acid.
