| titleOfInvention | A kind of preparation method of producer gas generator superfine basic copper nitrate |
| abstract | A kind of preparation method of producer gas generator superfine basic copper nitrate.Comprise the aqueous solution 1. configuring nitrate trihydrate copper, sodium hydroxide; 2. add sodium hydroxide and additive, the aqueous solution of cupric nitrate is evenly added reactor in 0.5h, the pH value controlling reaction solution is 7.5-9.0, temperature 60-90 DEG C, reaction 0.5-3h; 3. by sedimentation and filtration, mother liquor retains, and precipitation adds water, is pumped into by the suspension of precipitation after carrying out spraying dry in spray-drier and packs; 4. mother liquor pumps in decompression evaporator, and reduction vaporization, crystallisation by cooling, crystallization is packed through filtration drying.The present invention obtains stoping reunion maybe can extend the thick product of reunion required time as far as possible, and eliminate the step that centrifuge dripping repeatedly washs, coarse-cracking machine is levigate, micronizer mill is pulverized further, not only save time, saved equipment investment but also reduced energy consumption and environmental pollution, reduce product cost, and product can reach the same granular level of traditional technology. |
