Description
Technical field
The present invention relates to a kind of preparation of sodium hydroxide equipment, be specifically related to a kind of ion-exchange membrane electrolyzer that is provided with the evaporation purifying plant.
Background technology
The ion-exchange membrane electrolysis alkaline is state-of-the-art processing method in the middle of the suitability for industrialized production caustic soda in the world, has that energy consumption is low, three-waste pollution is few, cost low and the advantage such as convenient operation and management.The chlorine of by-product and hydrogen can synthetic hydrochloric acids, or deep processing chlorine derived product such as PVC, organosilicon and methane chloride etc.Caustic soda is widely used in the industrial sectors such as papermaking, weaving, printing and dyeing, enamel, medicine, dyestuff, agricultural chemicals, process hides, petroleum refining, animal-plant oil processing, rubber, light industry, also is used for the extraction of aluminum oxide and the processing of metal products.Ion film caustic soda adopts exactly the ion exchange membrane electrolytic saltwater and makes caustic soda (being sodium hydroxide), its cardinal principle is because the cationic exchange membrane that uses, this film has special selection perviousness, only allow positively charged ion to pass through to stop negatively charged ion and gas to pass through, namely only allow H+, Na+ passes through, and Cl-, OH-and the two poles of the earth product H2 and Cl2 can't pass through, thereby played and prevent that anodic product Cl2 from mixing mutually with cathode product H2 and the danger that may cause exploding, also played and avoided Cl2 and another product of negative electrode NaOH reaction and generate the effect that NaClO affects caustic soda purity.
In daily production, generally need further the alkali lye of direct extraction to be purified.Usually the method that adopts is to produce steam by boiler alkali lye is heated, and makes water molecules evaporation wherein, therefore need to consume a large amount of energy when alkali lye is purified.At present, common way is that the intermediate receptacle of packing into without the alkali lye of purifying is transported to the purification workshop, with certain remaining temperature, and through aforesaid pilot process this alkali lye with temperature is cooled off gradually when alkali lye has just extracted in the electrolyzer, caused the waste of heat energy.And the employed energy is the non-clean energies such as coal when generally producing steam, has more increased the weight of environmental pollution.
Summary of the invention
The technical problem to be solved in the present invention is: the ion-exchange membrane electrolyzer that proposes a kind of alkali lye purifying plant with taking full advantage of temperature more than the alkali lye and reducing polluted emission.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of ion-exchange membrane electrolyzer that is provided with purifying plant, comprise electrolyzer, described electrolyzer is connected with alkali lye output tube, hydrogen output tube and chlorine output tube, comprise steam boiler and pressure steam purification chamber, described alkali lye output tube is connected to the fluid inlet of described pressure steam purification chamber, and the steam outlet of described steam boiler is connected to the steam inlet of described pressure steam purification chamber.
The invention has the beneficial effects as follows:
The present invention arranges the steam purifying plant by the alkali lye equipped at outlet port at close electrolyzer, fully reduces the calorific loss that alkali lye causes in transportation.Obtained to reduce the effect of energy consumption, for contribution has been made in low-carbon (LC) production.
Having improved of technique scheme:
In order to use the extra energy, the hydrogen that goes out by electrolysis production is fully used, described steam boiler is hydrogen gas boiler, described hydrogen output tube is connected to the hydrogen input aperture of described hydrogen gas boiler.
