Abstract
The utility model relates to a device for producing a bleaching agent by using waste chlorine gas generated in lithium production, which comprises a chlorine gas collector, an absorption tower, an alkali storage tank and an agitating tank, wherein the collector is arranged on the anode of an electrolytic cell; the outlet at the upper end of the collector is connected with the gas inlet at the bottom of the absorption tower through a pipeline; the gas outlet on the top of the absorption tower is connected with the gas inlet of the alkali storage tank; the agitating tank is arranged below the alkali storage tank; and the bottom of the agitating tank is provided with a discharge hole. When production is carried out, firstly, the waste chlorine gas is collected in the fully-sealed electrolytic cell, the upper end of the anode of the electrolytic cell is connected with the collector, and the waste chlorine gas is led out of the electrolytic cell under the negative pressure of (1*10-3)-(9*10-2); then enough alkali liquor is prepared in the alkali storage tank and is stirred without stop in the agitating tank; and then, the waste chlorine gas is led into the alkali storage tank to react with the alkali liquor to generate a liquid mixture of sodium hypochlorite and sodium chloride. By adopting the device of the technical scheme and a method for the device, on one hand, the raw chlorine resources are saved, and on the other hand, raw materials can also be provided for industrial bleaching of bleaching linen and the like.
Description
Technical field
The utility model relates to a kind of device with the waste chlorine production SYNTHETIC OPTICAL WHITNER that produces in the lithium production.
Background technology
The fused chloride electrolysis is a preparation metallic lithium common method, and the recycling that anode produces chlorine is a thing that makes lithium Metal smelting industry headache always.The chlorine chemical property is active, and is soluble in water, and unpleasant irritating smell is arranged, the serious harm HUMAN HEALTH, and hardware or buildings had serious corrosion.The amount of chlorine that the electrolysis of quantity-produced lithium produces is bigger, must handle absorption as much as possible, otherwise can greatly destroy environment.
Existing treatment process generally is to draw chlorine in the electrolyzer by the device of a gas collection under hermetically sealed condition, its available chlorine content is about 7.5%, temperature is about 60 ℃, to react in its feeding lime, enter trench then, this has not only caused the pollution of chlorine water to plant area and surrounding environment, but also has caused the waste of chlorine resource, has caused bigger financial loss.
The another one aspect, at present, the a large amount of SYNTHETIC OPTICAL WHITNER of material demand such as bleaching burlap, these SYNTHETIC OPTICAL WHITNER need special the purchase and production, how will produce metallic lithium and bleach these industrial enterprises of burlap and combine, the waste chlorine of producing the metallic lithium generation is become the industrial bleaching agent, form a fecund energy bonded state, become a new research topic.
The utility model content
The technical problems to be solved in the utility model provides a kind of device and method with the waste chlorine production SYNTHETIC OPTICAL WHITNER that produces in the lithium production, pollutes to reduce chlorine, saves former chlorine resource.
In order to solve the problems of the technologies described above, it is a kind of with the device that produces waste chlorine production SYNTHETIC OPTICAL WHITNER in the lithium production that the utility model provides, include: chlorine collector, absorption tower, alkali storage tank and steel basin, wherein collector is placed on the anode electrolytic cell, the outlet of collector upper end is by pipe connection absorption tower bottom air inlet, air outlet, top, absorption tower connects the alkali storage tank inlet mouth, and steel basin is arranged with steel basin, and the alkali storage tank bottom is provided with discharge port.
Adopt the device with the waste chlorine production SYNTHETIC OPTICAL WHITNER that produces in the lithium production process of technique scheme, can directly the waste chlorine direct production of producing the metallic lithium generation be become to contain the SYNTHETIC OPTICAL WHITNER of a large amount of clorox, can reduce chlorine on the one hand pollutes, save former chlorine resource, on the other hand, raw material is provided for again industrial bleachings such as bleaching burlap.
Further, in order to improve the stability of chlorination process chlorine air pressure, between air outlet, top, absorption tower and alkali storage tank inlet mouth, be provided with Chlorine Buffer Vessel.
Simultaneously, in the technical program, the method with said apparatus production SYNTHETIC OPTICAL WHITNER includes following steps:
1) with in the hermetic electrolyzer of being collected in of waste chlorine, collector of client link on the anode of electrolyzer, under 1*10-3～9*10-2 negative pressure with the waste chlorine lead-out groove outside;
2) concentration of preparation capacity is 6 normal alkali lye in alkali storage tank, the stirring that does not stop under steel basin;
3) waste chlorine is fed alkali storage tank and alkali lye reacts, generate the mixing liquid of clorox and sodium-chlor.
Because waste chlorine and alkaline reaction generate clorox, cardinal principle of the present utility model is: CL2+2NaOH=NaCL+NaCLO+H2O
Reaction equation can be divided into for three steps:
CL2+H2O→HCL+HCLO (1)
HCL+NaOH→NaCL+H2O (2)
HCLO+NaOH→NaCLO+H2O (3)
Because the alkali lye price is relatively cheap, draw materials conveniently, and that the industrial SYNTHETIC OPTICAL WHITNER that is used to bleach requires its composition is not tight, be used for bleaching usually, contain NaCL to the bleaching performance without any influence, the SYNTHETIC OPTICAL WHITNER that adopts such method to make, not only solved the problem of environmental pollution of the waste chlorine in the lithium production process, and reclaim and saved the chlorine resource, economy has also improved a lot, the NaCLO of higher degree if desired can also be concentrated into mixing solutions saturatedly, and the mode that separates out NaCL from solution of lowering the temperature then obtains.
Further, as preferred version, find that by practice effect is best when the negative pressure in the step 1) is 1*10-2.
