The special fly ash classifier
Details：
I. High-efficiency coal ash classifier Jiangsu Yinengda Environmental Protection Equipment Co., Ltd is a high-tech enterprise specialized in manufacturing, research and development of powder conveying, classifying equipment. T-Sepax three-classification coal ash classifier developed by the company has obtained a national invention patent and three new utility patents, and was awarded the title of high-tech product in Jiangsu Province, which has been widely applied in more than 40 power plants and more than 800 cement plants in the country. What’s more, in the aspect of large capacity, the company walks in the forefront of the industry, it can produce the super-large high-efficiency T-Sepax classifier, with fly ash capacity of 100T/H and super fine cement of 600T/H. In 2000, the company introduced the Japanese Onoda O-Sepa classifier which is the most advanced in the field of classification. On the technological basis, the company successfully developed the new high-efficiency classification equipment. The classifying efficiency is up to over 90%, and the ratio of material and air up to 2.0 ~ 2.5Kg/m3 dry air. Compared with the existing turbine classifier, it has the following outstanding advantages: 1. The turbine classifier has boundary effect: the existing turbine classifier only accounts to a cyclone added a rotating turbine device, and the dust-laden air mixed with coal ash produces high-speed rotation after entering into the cyclone. Under the effect of the centrifugal force, the large particles are thrown to the sidewall and fall down, and at the same time due to the sidewall effect, the fine ash near the cyclone sidewall is thrown to the side under the effect of centrifugal force and mixed into the large ashes, which causes the fine ash classification unclean. 2. The airflow rotation has speed gradient: As the classification area is an annular area between the outer edges of the turbine and the sidewall of the cyclone and the airflow only enters from a single tangential inlet, the speed of the airflow at the area of the inlet is higher while the airflow far away from the inlet is lower, which causes the flow field in the annular classifying area to be unstable, thus affecting the classifying efficiency. 3. It cannot form a plane eddy: the turbine of the existing turbine classifier is only a simple straight cage rotor, which has no horizontal boards and the classifying blades are made from steel flat. And the generated rotating airflow is not horizontal eddy but the vortex. The speed of the airflow absorbed from the upper part of the cage is faster while the speed of the airflow from the lower part is slower, which affects the classifying efficiency. 4. It cannot effectively clean the large dust. The existing turbine classifier is designed to clean the large dust at the lower part of the assorting cylinder with the secondary air, but if the speed of the secondary air is too fast, it is easy to raise a large amount of falling dust and then it will affect the material classification at the upper part of classifying area, while if the speed of the air is too slow, there will be no cleaning effect on large dust. II. T-Sepax high-efficiency three-classification coal ash classifier (the structure is shown below) has completely overcome the shortcomings of turbine classifier, whose advantages lie in: 1. The designed straight cage rotor is a cage rotor composed of multi-layer horizontal boards and vertical classifying blades. The horizontal boards makes the airflow in the classifying area for stable horizontal vortex while the classifying blades of different shape make the classifying airflow that enters into the cage from the surface of the cage keep the same speed at any point, with the relative speed difference less than 5%, so the flow field at the classifying area is uniform and stable, and then the classifying precision is very high. 2. There are a number of guide blades with "concave" groove evenly arranged in the middle between the cage rotor and the outer shell, and the dust-laden air has to enter into the annular classification space shaped by guide blades and cage rotor along the tangential direction from a number of gaps about 15mm between guide blades. Since the presence of guide blades completely eliminated the sidewall effect, the fine ash content in large powder is greatly reduced and the classification efficiency is greatly improved. 3. The large powder that falls into the coarse ash bucket is washed by the rising airflow from the lower part, so the fine ash contained in the coarse ash will be taken to the classifying area again. 4.Due to the uniformity and stability of flow field and high rotation speed of the airflow, the centrifugal force and centripetal force generated are very strong, so the classification accuracy is very high, and feed air ratio can reach 2.0 ~ 2.5. Compared with turbine classifier (0.7 ~ 1.0), the feed air ratio is higher than 2 to 3 times. The air consumption for classification is only half the turbine classifier, thus greatly reducing energy consumption. The energy consumption of the classification system with processing capacity of 60T/H is only 120KW, while the energy consumption of the classification system with processing capacity of 40T/H is only 100KW
