Description
Technical field：
The present invention relates to one kind using desulfurization waste liquor, lead acetate as starting material, by filtering, stirring, heats, refilters
A series of flows prepare vulcanized lead.
Background technology：
China is one using coal as the country of main energy sources, with the rapid development of industry, the SO that coal burning generates2
Have become the major pollutants of In The Atmosphere Over China pollution.From 2002, China carried out large-scale SO in power industry2It administers
Engineering.With the beginning that power plant desulfurization is administered, large quantities of foreign countries' flue gas desulfurization techniques are introduced into the country by different desulfurization companies,
Mostly limestone-gypsum method among these.With the large-scale use of flue gas desulfurization coal industry at home, other cigarettes
Desulfurization method is also gradually used, is realized, including seawater method, ammonia process, magnesium processes, Dual alkali etc., among these, ammonia process just by
More and more extensive concern.Ammonia flue gas desulfurization technique is the SO done using ammonia in absorbent removing flue gas2Technique.The seventies
Just, Japan starts to develop ammonia desulfurizing process and succeed in succession with states such as Italy.But due to Technological Economy etc.
Reason is applied less in the world.Into after the nineties, with advances in technology and the transformation to ammonia process of desulfurization idea, amino are de-
The application of sulphur technology is in the trend gradually risen.
Currently, the most of coking coal chemical industry enterprises in Xinjiang region take wet method ammonia desulfurizing process technology.In desulfurization
Cheng Dangzhong, after salt content reaches certain value, desulfuration efficiency substantially reduces, and doctor solution becomes desulfurization waste liquor.At this point, enterprise needs to add
Desulfurization can just be continued by entering new ammonia source and discharging partial desulfurization waste liquid.Using the above method, the desulfurization waste liquor of coal chemical enterprise does not have
Deep exploitation is obtained, many coal chemical enterprises are sprayed at water on dump as coal blending.Although this method solves desulfurization
The place to go of waste liquid, surface seems that waste liquid discharge is less, but does not tackle the problem at its root actually.Cause environment secondary
Pollution wastes the raw material of industry, increases enterprise's production cost.The invention of desulfurization waste liquor recycling treatment technology is reaching section
While energy emission reduction, moreover it is possible to the sulphur in desulfurization waste liquor be carried out recycling, can be that domestic enterprise bring preferable economy to imitate
Benefit.
Specifically, the principal element for influencing the removing of coal chemical industry enterprises exhaust gas is two kinds of ammonium thiocyanate, ATS (Ammonium thiosulphate) salt
Content is more than 250mg/L or more in doctor solution, and coal chemical industry enterprises generally take recrystallization extraction secondary salt at present, and will extraction
Desulfurization waste liquor after secondary salt, which is sprayed on dump, to be recycled, and the secondary salt added value that can be extracted in this way is low, in former doctor solution
Sulfide content reduced by only 30%, cannot reach the requirement of enterprise.And the present invention is handled desulfurization waste liquor and is sent out using hydrothermal synthesis
Method can not only prepare the high zinc sulfide powder of added value, but also former doctor solution sulfide content is made about to reduce 60%, can
It is continued cycling through as doctor solution and utilizes progress secondary desulfuration.Circular economy production, environmental protection life may be implemented in coal chemical industry enterprises in this way
Production can also be that enterprise brings economic benefit.
For vulcanized lead powder body material, in order to reduce its production cost.The present invention uses the preparation with industrialization potential
Technique, the theory to turn waste into wealth have been prepared with blocky and flower-shaped powder body material.The material is to prepare luminescent material, the sun
It can utilize and the good matrix of environment protection type energy storage material, infrared detector material, there is wide application prospect in recent years.

The vulcanized lead powder that bright the method obtains is for luminescent material, anti-fake material, Coating Materials, electroluminescent powder, nonlinear optical
Material, photoelectric conversion material etc. raw material are learned, in photoelectric field, is commonly used in the exploitation of photodetector material, nano-sulfur
Change lead illuminator and has the characteristics such as response is fast, can work at room temperature.In photocatalysis field, photohole, quantum can be generated
Dimensional effect, causing energy level change, energy gap to broaden makes the enhancing of its redox ability, for a kind of catalysis material, has
Excellent photocatalytic semiconductor characteristic.PbS quantum application field is more extensive, especially in biomarker and diagnosis, shines two
In terms of pole pipe, laser, infrared detector, ion selectivity sensor and single electron diode.
