Abstract
The invention relates to a method for washing an anode bag for electrolyzing synthetic diamonds, comprising the steps of coarse washing with clear water, metal removal through reaction with dilute acid and fine washing with clear water. The method increases the washing efficiency of the anode bag by over twice compared with the prior art, reduces the labor force for washing by over 40%, greatly lightens the labor strength, greatly improves the washing quality and can effectively prevent environmental pollution thanks to zero generation of acid mist and zero emission of harmful wastewater in the whole washing process, improve the labor conditions, enhance the labor safety factor of the operators, simultaneously save acid amount by over 70% and water amount by over 50% and substantially lower the production cost.
Description
Technical field
The invention belongs to the synthetic purification techniques field of superhard material, particularly a kind of method for washing anode bag for electrolyzing synthetic diamonds.
Background technology
In known superhard material synthetic technology, need be with the synthetic pellet fragmentation of powder catalyst diamond, the anode of then packing into carries out refining.In this refining process, because all multifactor influences, the anode inwall often adheres to more material, as not cleaning up, will influence reusing of anode.Present purging method normally soaks with hydrochloric acid earlier, then by manually cleaning.The major defect that this method exists is:
1) this method needs the operator to clean repeatedly by hand, and time-consuming, labour intensity is big, and the cleaning interval is long, and cleaning efficiency is low, and cleaning quality can not get assurance, and then influences electrolytic efficiency once more;
2) adopt the salt acid soak, not only the hydrochloric acid utilization ratio is low, and consumption is big, the cost height, and be easy to generate a large amount of acid mists, and pollute Working environment, bring harm for operator's health;
3) need manually to fish for anode from hydrochloric acid, acid solution splashes on one's body the operator easily, causes personal injury, and the labor safety coefficient is low;
4) when antianode bag water washes, often produce a large amount of smog and spent acid solution, serious environment pollution, cost for wastewater treatment height.
Summary of the invention
It is low to the purpose of this invention is to provide a kind of labour intensity, the production efficiency height, and cleaning quality is reliable, and can reduce environmental pollution, saves the method for washing anode bag for electrolyzing synthetic diamonds of acid, water consumption.
Realize that the technical scheme that purpose of the present invention is taked is: this method is to carry out according to the following steps:
1) slightly wash: the anode that will be stained with material is poured in the industry washer, adds water washing according to a conventional method and takes out in 30～50 minutes;
2) remove metal: the anode after will slightly washing is inserted in the reactor, the adding mass percent concentration is 20～30 sulfuric acid or nitric acid or aqueous hydrochloric acid, reacted at normal temperatures 10～20 minutes, wherein sulfuric acid or nitric acid or aqueous hydrochloric acid add-on be by weight be 4 times of anode, take out then the anode drop only afterwards water wash to PH=4～5 and pull out;
3) fine purifiation: will remove anode behind the metal and pack in the industry washer, and add water washing according to a conventional method and took out in 20～30 minutes and get final product.
In the method for the invention, anode bag for electrolyzing is adopted the method for slightly washing, can remove the non-metallic material that accounts for bur total amount about 80%, and make metalliferous material be in naked state, favourable condition is provided for pickling is clear, and need not be sour, acid mist can be do not produced, pollution can be eliminated environment; Replace manual operations by operation of equipment simultaneously, time saving and energy saving.Residue about 20% metalliferous materials that are difficult to clean, take the method for diluted acid chemical reaction to remove, can reduce the consumption of acid effectively, and dilute sulphuric acid or rare nitric acid or dilute hydrochloric acid do not have volatility basically, can not produce acid mist, avoided pollution, also can not damage human body to environment.When carrying out fine purifiation, because adherent material of anode after the flushing and acid amount are very small, thereby water consumption can significantly reduce, and cleaning quality is reliable.
Clean anode bag for electrolyzing synthetic diamonds according to the method described above, its beneficial effect is:
1) this method makes the cleaning efficiency of anode improve more than 2 times than prior art, reduces and cleans recruitment more than 40%, and labour intensity is alleviated greatly, and cleaning quality improves greatly;
2) the cleaning whole process of anode does not have the discharging of acid mist generation and harmful waste water, can eliminate environmental pollution effectively, improves working conditions, and strengthens operator's labor safety coefficient;
3) can use the acid amount to save more than 70%, water consumption is saved more than 50%, thereby production cost is descended significantly.
Embodiment
Method for washing anode bag for electrolyzing synthetic diamonds of the present invention is by to the analysis and research of anode bag for electrolyzing bur and physicochemical property thereof, and by a large amount of test gained by the contriver.Evidence, this method can not only be improved working conditions effectively, reduces labor intensity, and eliminates environmental pollution, and removes metal and only need once finish in reactor, need not repeatable operation.Acid solution can recycle and reach about 30 days, and waste liquid can recycle, and can reduce more than 70% with sour amount; The labor amount reduces more than 40%, and production efficiency and anode cleaning quality are improved greatly, and production cost reduces greatly.Below in conjunction with embodiment method for washing anode bag for electrolyzing synthetic diamonds of the present invention is described further.
Embodiment 1
The method for washing anode bag for electrolyzing synthetic diamonds of present embodiment is undertaken by following technology: 200 kilograms of concentrated pouring in the industry washer of anode bag for electrolyzing that will be stained with the refuse material earlier, adding water according to a conventional method slightly washes, washing time is 30 minutes, can remove 80% of adhered materials total amount.Anode after will slightly washing again takes out from washing machine, and drop decontaminated water, insert in the reactor, the adding mass percent concentration is 20% aqueous sulfuric acid, reacted at normal temperatures 10 minutes, the oxidation and coming off automatically at once under the effect of acid solution of adherent metallics also can be stirred in the reaction process on the anode bag for electrolyzing, and effect can be better.Wherein, sulfuric acid or nitric acid or aqueous hydrochloric acid add-on are by weight being 4 times of anode.Take out the water flushing of the clean back of anode drop then, pH value in bath reaches at 5 o'clock and pulls drop out clean, anode after will washing is at last packed into and is carried out fine purifiation in the industry washer, adds water washing according to a conventional method and takes out in 20 minutes and can obtain clean anode, uses in next electrolysis.
