Typically collecting mill ventilation and other equipment used in wind turbines to be connected with the election one, two, three outlet, which increases the feed concentration of the dust stream classifier, and its separation efficiency caused some impact, Meanwhile, due to the design or installation of piping unreasonable, making duct separator (between the guide vanes and volute) is easy to fouling, resulting in a separator space narrowing, wind farms can not reach a uniform steady state, the election greater impact on the performance of powder machine. Separator engaged in commissioning work to solve the fouling problem can be caused by unreasonable several piping: 1, fouling cases within a duct 1: The most common traditional process of grinding tail pulling duct access selected a powder outlet, pull on the duct did not fill valve to adjust the volume with the wind mill. But this arrangement question arises: In a duct into the wind at the starting bell has been into the secondary air ducts are present fouling. Fouling height up to 500mm or more. Solution: You can expand the bell at the bottom of the inlet air to increase a fill, pull the original wind pipe outlet shut up. New additions to be designed to calculate the size of the outlet. Principles for calculating the amount of wind balance principle that once the election powder into the air duct in the total amount remains unchanged, pulling the wind pipe air volume air volume required for the mill, fill the rest of the new outlet supplementary amount of wind. Design wind speed by pulling the wind pipe of 16-18m / s, the new addition of the outlet of 20-23m / s calculation example: O-Sepa3000 separator for φ3.8m * 13m combined grinding system, the mill ventilation need 50000m3 / h, while the primary air classifier need 3000 * 60 * 67.5% = 121500 m3 / h, (once the wind with the wind of the total amount of 67.5%). At this point the new additions air vents need wind of about 70000 m3 / h ,, once air inlet area is 1.7 * 1.1 = 1.87m2, fill the outlet area needs 0.92m2, height can be set to about 840mm. Need to set up a simple tune the outlet valve, but also in the pipeline lookout additional adjustment valve. Operation pull duct pressure based on mill end, the actual situation in the material flow rate swap mill for 2 dampers adjusted appropriately for example: there beneath a mill in an air duct directly elected pull tail arrangement of the powder will be below the first outlet The arrangement form, fill in an air vent above. This arrangement will produce a solution to the duct fouling: pull the wind in front of the outlet pipe once the lower sides of the rectangular open mouth, then two rectangular pipes. The original outlet shut up, so grind pull the tail wind from the upper part of the duct into the separator, the size of the rectangular opening in the same principle of balance by the amount of wind design calculations. To reduce the mill tail pull fouling rectangular duct to the mouth, and can be welded in this an inclined baffle. Improved arrangement of rectangular mouth around two secondary duct fouling there are other forms of access to other collecting devices arranged in the secondary air duct, such as hoists or conveyor scatter dust, etc., is not due to access location reasonable (if the interface is located in the lower half), will cause the secondary air duct fouling solution: simply change it in the upper half can also pay attention to the pipeline area calculation.
