 Flowchart:

The crushed and weighed quicklime from the constant weight feeder enters the three-stage lime hydrator where water is mixed with the quicklime in the required proportions to achieve complete hydration. According to different process requirements, it is able to make serous fluid become different sized hydrated lime powder by   the air separator.

Principles and advantages of three-stage dry power hydrator

1. Three stage reaction with water distribution 

The hierarchical & scientific distribution of water can make the calcium oxide to be fully pre-hydrated. After contacting with reasonable water in the first stage reaction chamber, the mixture enters into the second stage. This process is the best time for hydrating. When entering into the third one, hydrated lime is already semi-dry state. Three stage hydrator can finally make the calcium completely become the fluffy powder. And the entire reaction process just needs 8-15 minutes.

2.Time control

It will control the time of reacting water and calcium oxide, fully hydrating just needs 8-15 minutes

3. Insulation function

Hydrator has good insulation function. As we all know, temperature may influence the rate of chemical reaction. The unique design makes it possible to reuse the vast heat which generated from the reaction inside the hydrator. It will raise the inner temperature to 60 degrees by only 3-5 minutes and make the calcium oxide to be fully hydrated.

4 Feeding process control

To pour the needed materials into the first-stage reaction chamber, screw feeder plays a extremely vital use for preventing hot steam and dust flowing back into the screw feeder, otherwise that will affect the accuracy of sensor.

5. Remove dust to keep clean and healthy

 This device, according to environmental requirements, equipped with our patent dust remove device, will solve the problem of the steam and dust pollution produced during hydrating ,so that ensure the clean of the environment and the health of workers.

6.Main uses of Lime hydrating system

1.chemical lines:produce additive(hydrated lime)

2.Environmental: Flue Gas Desulfurization, Water and sewage treatment.

3.Lime plant: produce hydrated lime

4.Iron works: produce hydrated lime as flus for sintering

 Important matched part----patent dust collector

Dust Collector

1.widely use:

To deal with the dust and harmful gases produced in the process of lime hydration of steel & Iron plants, power plants, chemical plants etc.

2.principles and features:

It can meet the needs of a variety of processes. This equipment is adopted the atomization dust removal and the impact water filtration technologies, enable to deal with the dust and harmful gases produced in the process of lime hydration. That means the abandoned dust of quicklime can be recycled and there is no dust pollution at the scene environment. It will help burnt lime hydrator reasonably allocate water needed during the lime hydration. Different specification of lime hudrator will be choosed according the quicklime feeding amount of different enterprise to hydrate quicklime acdequately.

3. advantages:

After the dust removal device and the lime hydrator forming a complete set, the lime hydration ratio can exceed 90%, the dust extraction ratio can reach 99%.
