MD fly ash dynamic classifier
The salt-rich fly ash sorting system is a large-scale high-efficiency, precision forced air flow classification system that our company has carefully developed based on the existing powder selection technology. The system's main equipment MD dynamic classifier absorbs the advantages of the same type of equipment at home and abroad, and is particularly suitable for power plant raw ash fineness and loss of ignition fluctuation range, small technical renovation site, supporting control system performance requirements of China's national conditions, is a power plant Ideal special equipment for fly ash sorting. The main features of this technology are as follows:
● High sorting efficiency: Scientifically combining the principles of eddy current classification, inertial classification, and centrifugal classification, the classification efficiency is high, so the output rate of the finished product can be greatly improved.
● Flexible adjustment methods
: It can be adjusted
by a variety of means including the opening degree of the main air valve, the rotation speed of the impeller of the classifier, the opening degree of the secondary air valve, and the adjustment of the positive and negative zero positions of the adjusting pipe (bag dust collector).
● High classification accuracy
: Various measures have been taken to ensure the classification accuracy. The 45um sieve balance can be adjusted at any position from 1-20%, and the positive and negative errors do not exceed-percentage points.
● Strong applicability
: the fineness of the original ash is uneven, and the uneven ash amount has no effect on the quality of the finished ash.
● Large processing capacity
: Adopting forced vortex centrifugal separation technology, especially in large processing capacity, has a great advantage. It can handle more than 100T / h. It can be matched for power plants with various installed capacities.
● Easy operation
, all can be controlled digitally on the operation panel. Generally, workers only need to train for half a day, as long as they strictly follow the procedures to operate, they can be skilled at the job, without the need to accumulate experience.
● Abrasion-resistant design
, which fully considers the wear-resistant and abrasion- resistant
from the design principle and the design of the system operating parameters. At the same time, abrasion-resistant measures have been taken for the easy-wearing parts of the system: the fan's surrounding board is lined with corundum, the impeller is thickened, and surfacing The classifier is equipped with removable wear-resistant cast steel blocks, the inclination of the blades, and the design and manufacture of the turning radius of the elbow are considered from the point of least resistance to wear. The elbow is lined with ceramic sheets and thickened externally.
● The investment is low. There is no need to install an electric dust collector and other dust removal equipment between the main fan and the cyclone separator, thus saving a lot of investment.
