Flowchart
The crushed quicklime enters screw feeder from quicklime silo, then weighed by screw weigh, after that, quicklime enters into three stage hydrator to react with water. After complete reaction in hydrator, the finished hydrated lime fine powder will flow into hydrated lime silo though a screw feeder. According to different requirements, after the hydrator, it is able to produce various sized hydrated lime powder with an air separator or make hydrated lime fluid followed.
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.
Application Areas and Key Functions
Multistage lime hydrator is widely used in lime producing line for lime plants, sticky material cleaning device for ironworks, desulfurization equipment, calcium treating machine in sewage treatment, high quality hydrated lime producing line.
Through our threestage dry power hydrator, burnt lime will be hydrated into a fluffy powder because of the hierarchical & reasonable water distribution and multi-channel process of this hydrator.
Principles and performance
Our advantages and principles of three-stage dry powder hydrator
1. It will control the reaction time and fully hydrate the CaO by only 8-15 minutes to realize complete hydration.
2. Hydrator has good heat-insulating property.
The unique design makes a lot of heat generated in the reaction of CaO to be converted inside and reused. It will raise the inner temperature to make the CaO to be fully hydrated.
3.Feeding process control: It is use screw feeder to Send materials into reaction cabin.
Advantages: There are lots of hot steam and dust when CaO contact with water. This feeding way will prevent them flowing back to the screw feeding counter, so that will not affect the accuracy of sensor.
4. technical water distribution
We adopt technical water distribution, the best distributing proportion and time to contribute to fully hydrating.
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 work site and the dustiness at the vent of dust collector be less than 30 mg/m3 ,which do a great help to keep healthy of workers.
6. The whole machine can be controlled by a PLC system and it can be adjusted according to requirements, which not only keep healthy of workers but improve the working efficiency. Besides, According to client’s requirements, our hydrating machine can mating follow up equipments such as lime pulp machine, dregs extractor, filter and so on, in order to produce high purity hydrated lime emulsion with different Ca( content.
7. Standard technology index
capacity 1-30t/hr
percent conversion: 96%
Equiped with our patent dust collector
Main principle
Dust and steam enter dust removal water cabin though dust cage and dust pipe. After complete treating with the dust, discharge clean gas from the vent. During solving dust and steam, water in cabin turns out hot slime water by absorbing dust and steam, then via high pressure pump, throwing into pipes for cycling usage in the water system.
Advantages
1. Realize the cycling usage of water and the reuse of overflow dust
2. Recycle waste heat of hot steam which can improve the hydrating rate , save energy ,solve the dust pollution problem and raise working efficiency finally.
