Desulfurization cyclone Centrifugal sedimentation is a common principle of separation. When the two-phase mixture to be separated enters the hydrocyclone tangentially from the periphery of the hydrocyclone at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is produced. Due to the difference in particle size between coarse and fine particles, they are subject to different sizes of centrifugal force, centripetal buoyancy and fluid drag. Due to centrifugal sedimentation, most of the coarse particles are discharged through the bottom flow port of the cyclone, while most of the fine particles are discharged by the overflow pipe, so as to achieve the purpose of separation and classification.
How it works
In the desulfurization equipment, the desulfurization cyclone has the advantages of strong processing capacity, simple and portable structure, low maintenance cost, easy to replace wear parts and so on, which is widely used in the field of power FGD.
The directional inhibition technology of short-circuit flow is adopted to improve the feeding stability of gypsum slurry and reduce the loss of overflow short-circuit flow;
The multi cone non-linear centrifugal classification technology can effectively improve the centrifugal strength of the internal flow field of the cyclone and optimize the concentration and classification effect;
The lining design of various wear-resistant materials effectively improves the operation life of cyclone;
Energy saving and environmental protection, through the pre concentration treatment of gypsum cyclone station, the energy consumption of dehydration equipment is reduced.
According to the construction section, it can be divided into one stage classification cyclone and two stage staged cyclone.
According to the function, it is divided into classification cyclone, dewatering cyclone, desliming cyclone, slag removal cyclone, concentration cyclone and special cyclone for tailings dry discharge.
Primary stage cyclone
More than 500 tons a day for a wide range of non metal ore dressing and classification of a single stage. Hydrocyclones can be arranged either individually or in groups according to different processing capacity. In the case of higher feed concentration, it has higher classification efficiency and finer overflow fineness, the overflow product is forced to be uniform, and the separator efficiency is 5-10% higher than the commonly used spiral classifier, which is conducive to the improvement of mill utilization coefficient.
(1) Large angle Hydrocyclone
The cone angle of hydrocyclone is large, up to 180 degrees (also known as flat cyclone). It is suitable for high concentration, high mineral ratio, overflow fineness requirement below 60% of - 200 mesh, especially suitable for primary grinding of iron ore in stage grinding separation process. The hydrocyclone with this structure has a series of advantages, such as uniform overflow particle size, light over grinding phenomenon of overflow products, and large adjustment of bottom abortion rate without affecting the normal operation of the hydrocyclone. Compared with the same hydrocyclone, the first stage grinding capacity can be increased by 10-25%.
(2) One stage high fineness classification cyclone
It is suitable for the occasions where grinding fineness of - 200 mesh is more than 80%. Because of the fine size of classification, even if the ordinary structure cyclone reaches the required grading size, the classification efficiency will be greatly reduced, the amount of return sand will be increased, and the new ore feeding amount of the mill will be low. By changing the structure of the first stage high fineness classification cyclone, the overflow run out and underflow pinch degree are reduced, and the high overflow fineness and high classification efficiency are maintained at the same time.
Two stage classification cyclone
Two stage classification hydrocyclone is widely used in secondary inspection and control classification of various metal and non-metallic ores. The specifications of hydrocyclone range from 75mm to 660mm, which can be used in different processing capacity and different requirements of grinding fineness. The unique structure design of hydrocyclone can make the overflow fineness of two-stage hydrocyclone from 75% to 95% of - 200 mesh.
JY series hydrocyclones are a new generation of high-efficiency classification hydrocyclones developed and produced by our company on the basis of absorption and digestion hydrocyclone classification technology. The high efficiency and long service life of the single cyclone separators have been successfully used in domestic non metal ore classification units (550m3 / h)
