(3) when stopping concentrating, first close conduction oil recycle unit, turn off vacuum pump, first balanced valve, the second balanced valve, the 3rd balanced valve, outlet valve are adjusted to manually, in slowly opening atmospheric valve goalkeeper's equipment, emptying is to atmospheric pressure state, while hot concentrated solution is discharged from concentrated solution outlet, start discharging, complete once concentration.After concentration, close all valves, the first balanced valve, the second balanced valve, the 3rd balanced valve, outlet valve are adjusted to automatically, open vacuum pump, after equipment enters and stablizes vacuum state, be adjusted to charging electrically operated valve automatically, feed.If continuing to concentrate, then open electrical heating switch, enter automatic evaporation process.If stopping concentrating, enter shutdown procedures.
(4) shutdown: after chemical nickel liquid waste treatment system completes again feed step, all electrically operated valves are adjusted to manual halted state, when conduction oil temperature is down to below uniform temperature, close vacuum pump, and slowly open emptying valve, make equipment enter atmospheric pressure state.Close cooling blower, spray pump, conduction oil oil circulating pump, close all valves, deenergization, lock electric control box, arrange scene.
(5) safeguard: tap water can be added and be carried out pipeline and equipment.
The beneficial effects of the utility model:
(1) when using this chemical nickel liquid waste treatment system to process chemical nickel waste liquid, it is not necessary to any medicament of extra interpolation, and chemical method cannot can be processed nitric acid washing trough waste liquid up to standard and add in chemical nickel waste liquid.While concentrating chemical nickel waste liquid, also consumes nitric acid bubble groove and clean waste liquid.
(2) this chemical nickel liquid waste treatment system is vacuum tightness system, thus produces without gas with contaminated air, and concentrated solution also has no irritating odor, and after cooling, i.e. solidification becomes jelly.
(3) this chemical nickel liquid waste treatment system is vessels not under pressure, and heating-up temperature is the highest, and therefore safety coefficient is higher.
(4) processing cost of chemical nickel waste liquid is about the 1/3 of original processing cost, greatly reduces business processes cost.
(5) for the former water of chemical nickel waste liquid of also high phosphorus, nitrogen, nickel and the Organic Pollution factor, after handled by this chemical nickel liquid waste treatment system, condensation of water can reach: total phosphorus≤0.5mg/L, total nickel≤0.1 mg/L, CODCr≤100 mg/L, ammonia nitrogen≤8 mg/L, total nitrogen≤20mg/L, the most without phosphorus, nickel in condensed fluid, COD value is the lowest, and nitrogen content is the lowest, this kind of water reaches three grades of discharge standards of sewage, is substantially reduced the pressure to environment.
(6) concentrating spent liquor produced is about 1/10th of original volume, forms solid matter and transport more convenient without mobility, storage, take up an area less after cooling.And because in concentrated solution, nickel content is original chemical nickel liquid waste concentration more than ten times, nickel ion concentration is higher, can carry out metal smelt, have recovery value.
