Processing system and technique.
Background technology
Flyash curing stabilisation refers to by flue gas purification system（Reaction tower and sack cleaner）Collected dust, passes through
It is stabilized using chelating agent or inorganic medicament etc., obtains the process that flyash curing stabilizes product.Refuse Incineration Process
The flying dust of middle generation is because of its complicated component and contains a certain amount of toxicant, therefore need to separately be handled with generated clinker, passes through
Flyash curing is crossed to stabilize to meet《Consumer waste filling and embedding contamination control standard》（GB16889-2008）Environmental requirement, to
It transports landfill yard and carries out landfill disposal.
Flyash curing stabilization system is reacted usually using chelating agent with the heavy metal in flying dust, while mixed with cement
Conjunction is cured.To reduce transportation cost, chelating agent is mostly concentrate in manufacture, is needed when carrying out flyash curing stabilisation
Chelating agent concentrate is diluted to the concentration finally needed as the case may be, current flyash curing stabilization system is universal
The process that chelating agent is diluted using a water supply.
Since flyash curing stabilization system is not 24 continuous throughout the twenty-four hour24s, therefore the material in above-mentioned technique is being mixed
After be easy to be adhered to equipment inner casing, stirring rotator, at Dump gate, therefore each shift of worker is required for after hours to mixed
Blender is closed to be rinsed, meanwhile, flyash curing stabilizes in workshop because of the reasons such as equipment room is poorly sealed, usual ground and
Platform has also been easy flying dust airborne dust, therefore also needs to be rinsed ground, and containing without place in the sewage and sludge rinsed
If being directly discharged into sewerage in factory secondary pollution may occur for the heavy metal of reason.
Secondly, when stabilizing fly ashization is handled, flying dust weight scale, cement weight scale, mixing and blending machine are in charging discharging
Slug phenomenon can be generated because of inner and outer air pressure imbalance in the process, and then generates dust, had both influenced staff's health,
It can cause air pollution.

12；Liquid medicine weight scale 17, flying dust weight scale 13, cement weight scale 12 output end connect respectively with mixing and blending machine 14.
The stabilizing fly ash processing system further includes sewerage and dedusting water wash system, and dedusting water wash system includes dedusting
Water tank 8 and remove dirt pits；Dedusting point is located at flying dust weight scale, cement is weighed, the pneumostome of mixing and blending machine 16 and be mixed
At machine discharge port 15, except being provided with above dirt pits apart from adjustable dust hood 9, removing has certain distance between dirt pits and dust hood
And adjustable berth away from, it is ensured that dust hood only aspirates the dust for raising out out of each equipment, without being drawn into each equipment
Material.
The run-off 2 of sewerage is connected with an input terminal of dust-proof water tank 8 by Self-priming sewage pump 3 and is communicated, and upper one
After shift, the sewage of flushing device and workplace generation first passes through sedimentation basin precipitation, run-off is entered back into, next
Before the stabilizing fly ash system that brings into operation, Self-priming sewage pump is pumped into dust-proof water tank by sewage is rinsed, and both may be used as flying dust in this way
The water source of secondary water supply dilution chelating agent in stabilizing treatment technique, also avoids flushing sewage and is directly discharged into sewerage in factory
Cause secondary pollution；Dust-proof water tank 8 another input terminal and technique water tank 1 connection communicate, process water can individually or with overflow
The flushing sewage flowed in pond enters dust-proof water tank simultaneously, to ensure that secondary water supply dilutes the water consumption of chelating agent；Dust-proof water tank 8
It by wind turbine 18 with respectively except dirt pits connects, wind turbine 18 and respectively removes and is provided with nozzle 19 between dirt pits, nozzle 19 connects with technique water tank 1
It connects and communicates, it is preferable that as shown in Figure 1, the pipeline of water inlet end access the Joining Technology water tank and dust-proof water tank of nozzle, dust-proof water tank
8 output end is connected with the input terminal of liquid medicine weight scale 17 and is communicated.
In addition, dust-proof water tank is connected with technique water tank, one side technique water-dilutable is simultaneously into the flushing of dust-proof water tank
On the other hand a small amount of harmful substance present in sewage since flying dust processing is carried out by batch, dilutes chela as secondary water supply
The main water source of mixture, the process water in dust-proof water tank constantly enter new water also with the use of processing batch, to avoid into
Excessive concentration of the dust generated when the flushing sewage and the flying dust treating system operation that enter dust-proof water tank in dust-proof water tank, shadow
Ring flying dust treatment effect.
