General introduction of wet type lime slaker:
Wet type lime slaker is also called lime slaker, lime slaking machine, drum lime slaker and lime milk machine. It is rotary drum type lime slaker, which is used to slake the quick lime (calcium oxide) into lime milk. The wet type lime slaker is mainly used in steel, chemical industry, metallurgy, papermaking, power plant desulfurization, aluminum oxide, titanium dioxide, sugar, biology pharmacy, soda ash manufacturing and other industries.
Working principle of wet type lime slaker:
Wet type lime slaker is mainly composed of rotary cylinder, roller device, drive unit, etc. There are filtration device, discharge device and spray device at the end of the rotary cylinder. Its interior is divided into four areas: preliminary slaking, slaking, homogeneous area and slag milk separation area. The rotary lime slaker working principle is via the drive unit to rotate the cylinder. The rotary motion of cylinder drives inside the cylinder lifters, feed plate and damping plate, such as dust blocking plate, guide plate rotation instead of mixing of slaking method.
Features of wet type lime slaker:
1. Lime milk quality is good and exquisite, with high production of pulp, and the concentration of lime milk can be adjusted conveniently, by increasing and reducing of feeding amount to control lime milk concentration control.
2. Fast slaking and high efficiency. Due to taking full advantage of the lime slaking exothermic, remain the state of boiling in the slaker material, losing small heat, very fast slaking in 15 minutes fully slaked to the high digestion temperature.
3. Good operating environment, realized the mechanization production, slag removal is convenient, the use of lime slaker machine at the back of the installation of the dregs removing machine, 95% of the ash in the lime emulsion can be separated.
4. High mechanization degree, easy operation, digestion, slag fully realized mechanization, there is no need of personnel in the normal production process operation, low labor intensity.
5. Sealed ends by the special design, can guarantee no leakage, implements the production site clean.
6. Optional PLC control system, PLC through analog signals (4-20 ma) by the frequency converter control feed rate and the main engine rate of revolution, realizing automation production, the vector control system of type inverter can through self-learning or artificial set low frequency torque compensation, realize the big moment of low frequency of digestive machine start, greatly improves the digestion machine startup performance. Control system of dust, moisture proof processing, make it more applicable to the dusty and humid environment.
7. The lime slaker does not produce harmful waste gas in the process of digestion, the emissions of gases contain a small amount of water vapor of calcium hydroxide, such as the need to eliminate, can be equipped with dust removal device for dust removal process.
