The invention discharges no wastewater and exhaust gas, reduces the pollution to environment, improves the utilization ratio of raw materials, lowers the production cost, reduces the production time and improves the production efficiency.
Description
Technical field
The present invention relates to nickelous nitrate, refer in particular to a kind of processing method that adopts high-purity metallic nickel to produce the special-purpose nickelous nitrate of priming system.
Background technology
The safety problem of explosive industry enterprise is related to the final and decisive juncture of an enterprise, and safety problem, environmental issue are to be related to the prerequisite that can an enterprise Sustainable development.Nickel hydrazine nitrate is as a kind of novel priming explosive, mechanical sensitivity is low, and non-environmental-pollution is the priming explosive that a kind of extremely is worthy to be popularized, it is short that this medicament has the technological process of production, the starting material source is wide, reasonable price, the advantage that manufacturing cost is lower, bursting point was 280 ℃ in five seconds, flame sensitivity value Hso=60cm, suitable with lead styphnate, mechanical sensitivity is a little less than the dinitrobenzene diazotic acid, all compatible with priming system material commonly used, its security simultaneously is good, fast light, non-hygroscopic, do not dye, because pharmacy and assembly technology are rationally feasible yet, eliminated the pollution of waste liquid to environment, produce safe in utilizationly simultaneously, the mixed economy cost is low, and wide application prospect is arranged.And the quality product of nickelous nitrate, directly have influence on the quality of priming explosive, from 2002 since red mechanical chemical industry limited liability company produces, because the quality accident that the quality problems of priming explosive cause emerges in an endless stream, and even reach and once destroy millions of capsular quality accidents, the millions of units of financial loss, it is a difficult problem to be solved that the quality problems of nickelous nitrate become explosive industry enterprise.
Summary of the invention
The objective of the invention is to be improved, a kind of processing method that adopts high-purity metallic nickel to produce the special-purpose nickelous nitrate of priming system is provided at shortcoming that exists in the background technology and problem.
Technical scheme of the present invention is a kind of processing method of producing the special-purpose nickelous nitrate of priming system that may further comprise the steps of structure:
1) high-purity metallic nickel is put into reactor, add the dilute nitric acid solution about entry or 8%, be heated to 80-100 ℃, whole system is carried out under normal pressure;
2) add nitric acid reaction, the high-temperature gas passes cooling of generation is so that water absorbs it;
3) NO of Chan Shenging
XAerating oxygen is to having the NO of reductive action
XCarry out oxidation, make it become NO
2, absorb and the utilization of system internal recycle through 2-3 level acid mist scavenging tower, up to absorbing fully;
4) water behind the absorbing NOx has become HNO
3Solution is recycled, and participates in oxidizing reaction again;
5) adjusting discharging behind the pH value 2-4 of nickel nitrate solution, recrystallization, dehydration, check, packing at last gets final product.
High-purity metallic nickel purity of the present invention is more than 99.90%.
Advantage of the present invention and beneficial effect:
The present invention adopts the high-purity nickel more than 99.90% to produce the special-purpose nickelous nitrate of priming system, and the nickelous nitrate pH value of production is 2-4, meets priming system to the particular requirement of the pH value of nickelous nitrate and the requirement of other aspect of performances.Recycle of the present invention absorbs the water that becomes lower concentration nitric acid behind the nitrogen peroxide, abandons the method for soda ash absorbing NOx, forms oxynitride such as nitrogen protoxide and reuptakes after by dioxygen oxidation, and oxynitride reaches zero release, absorbs very abundant.Compare with traditional soda ash absorption, there is not waste water and gas to discharge fully, both reduced pollution to environment, improved utilization ratio of raw materials again, reduced production cost,, reduced the production time owing to adopt the excessive production technique of nitric acid, improved production efficiency, the product of producing is far above the chemical pure quality standard of country.
Bright spot of the present invention has following three aspects:
1, high-purity metal nickel and nitric acid reaction produce the high purity nickelous nitrate, have become suitability for industrialized production from experiment.
2, adopt cyclic utilization method, do not have waste water, waste gas to discharge fully, realize zero release, technology is environmental protection very, has improved raw-material utilization ratio, has reduced production cost.
3, this technology meets pH value particular requirement and the purity requirement of priming system to nitric acid, guarantees the safety that priming system is produced, and reduces the quality cost that priming system is produced.

Embodiment
Specific embodiments of the invention:
Because the special-purpose nickelous nitrate of priming system is very high to purity requirement, so must prepare, react with nitric acid after being heated to 80-100 ℃ with the metallic nickel more than 99.9%, its reaction equation is as follows:
Ni+HNO
3→Ni(NO
3)
2+NO
2↑+NO↑
Oxynitride such as NO can generate NO with airborne oxygen reaction at normal temperatures
2:
NO+O
2→NO
2
NO
2Very easily absorbed at normal temperatures and generate nitric acid by water:
NO
2+H
2O→HNO
3+NO↑
NO is continued oxidation by airborne oxygen and generates NO again
2, NO
2Sponged by water again, after absorbing by multistage circulation, oxynitride reaches zero release.
Solubleness is big especially during at last owing to nickelous nitrate high temperature, and the little characteristics of lyolysis degree were carried out crystallization when temperature was low, dewatered then, check, packed.
Quality inspection report of the present invention:
Embodiment of the present invention only is the description that preferred implementation of the present invention is carried out; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design philosophy of the present invention; engineering technical personnel make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
