A kind of medicament of stabilizing fly ashization processing based on XRF detections provided by the invention becomes more meticulous addition method, fully
Consider that the addition of chelating agent and process water in real work is a homestat in ground, it is desirable that chelating agent and process water
Total amount keep definite value, fine granularity is presented with the flying dust after stabilizing in appearance, and required chelating agent and
The amount of solution of process water is relatively-stationary, if process water adds very little, flying dust is too dry, and the flying dust after stabilisation will appear powder
Dirt, powder, can not both ensure stabilization effect, also will appear flying dust airborne dust；If process water adds too many, after leading to stabilisation
Flying dust moisture content it is excessive, for flying dust in bulk group dress, pureed, stickiness is bigger, both wastes process water and medicament, is also unfavorable for fast
Speed is poured out from container by flying dust is stabilized.As it can be seen that due to Pb total amounts difference, the chelating dosage needed in the flying dust of every batch of
Also different, there is the risk for wasting medicament phenomenon and may not be up to standard in the fixation medical method in present production practices.By online
XRF detections can calculate the chelating agent and water dosage needed for every batch of flying dust in real time so that treatment effect more optimizes.This hair
It is bright to ensure that manufacture stabilizing fly ash is up to standard, moreover it is possible to which that reduces chelating agent adds cost, is more in line with modern intelligent water
Flat development improves the reaction speed of system process problem, and stabilizing fly ashization processing is improved to the pipe that becomes more meticulous by extensiveization
Reason.
A kind of medicament of stabilizing fly ashization processing based on XRF detections provided by the invention becomes more meticulous addition method, although
The normal detection to the flying dust after stabilization processes cannot be replaced, but the flying dust after stabilization processes is disposing it into landfill yard
Before, according to laws and regulations and the regulation of operation standard, it is necessary to be detected accordingly, reaching standard could fill, if do not reached
Mark, then must reprocess again；And once there is situation not up to standard, to the process for stabilizing flying dust reprocessing of respective batch
It is extremely complex, considerably beyond in stabilisation link single treatment cost up to standard.And the present invention can effectively improve flying dust
Compliance rate reduces the frequency and treating capacity that flying dust not up to standard occurs, additionally it is possible to and the waste of chelating agent is avoided, is saved the time, drop
Low overall operation cost.
