Introduction of lime hydrated plant:Lime hydrated plant production line is also known as calcium hydroxide production line. Quick lime digester dust removal device installed in the production line is widely used in lime plant, iron and steel plant, power plant, chemical plant and other industries.
The production line of hydrated plant is to crush the qualified calcium oxide (CaO) lump material from the jaw crusher to about 40 mm in size, and send it into the storage tank silo of calcium oxide by bucket elevator. The calcium oxide in the silo is preliminarily digested by the first digester of calcium hydroxide through the steady flow conveyor quantitative and steady weight system. When the primary digestion of calcium hydroxide is completed, it enters the second or third digester to make oxygen. Calcium carbide is completely digested and decomposed to produce qualified primary products of calcium hydroxide with a digestion rate of 98%. (Digestive system is divided into single-axis, double-axis and multi-axis models according to capacity requirements.) The digested and decomposed calcium hydroxide is fed into the separator by the semi-finished screw conveyor. The separator completes the separation of impurities and the classification of fineness. The qualified and high-quality products are finished after the classification. The finished product conveyor and the hoist are discharged into the finished calcium hydroxide tank warehouse and packed separately. All the pollution nodes of the production line are completed by pulse precipitator, and the dust collection rate reaches 99.5%.
Systematic characteristics of lime hydrated plant:
1. Innovative design of mixing structure: This machine adopts shear mixing with high-efficiency composite spiral curve structure. Under the action of the material, the shearing effect is produced between them to ensure the full mixing of water and material. At the same time, the blade surface is designed to have self-cleaning function when working, so as to ensure the continuous and efficient operation of the equipment.
2. Advanced PLC Control System: Advanced Auto-control Screen
3. Frequency conversion speed regulation drive system: This machine adopts frequency conversion speed regulation motor, which can automatically adjust the mixing speed and reaction time of materials with different properties. The famous brand vector frequency converter is selected for the frequency converter, which has large starting moment and stable and reliable operation.
4. Efficient and energy-saving environmental protection dust collection system: The dust collection system adopts special pulse bag filter with dust removal efficiency as high as 98%. The imported filter bag is durable and has a long service life, which ensures that the waste gas emission of enterprises meets the national environmental protection standards.
5. Superfine and efficient classification equipment: The system is equipped with air separation classifier, the fineness of finished products can be adjusted in 200-400 mesh.
6. Compact structure and high cost performance: The whole set of equipment has compact structure, small floor area, and reasonable production line process layout.
7. The ratio of lime and water is controlled by PLC and control valve, which can automatically adjust the raw materials of different properties and the finished products with different quality requirements, thus ensuring the quality of products.
