Grind the dust catcher impingement inertial separator

Impingement impingement inertial separator grinding polishing filter filter separator is commonly used in the dust air flow channel erected many vertical planar or cylindrical piece to dust. When dust airflow around the vertical obstacle logistics obsolete, part of the dust particles because of their inertia will collide with the obstruction and adhesion in the above, then separated from the gas. Impact of separator are commonly used to recycle acid mist. Impact horizontal separator structure characteristics of grinding polishing filter filter structure, it consists of a shell, hold the plate, the framework of pipe orifice plate and the impact plate. There are several vertical slit on orifice. The slit width of impact plate is twice the width of slit on orifice. Impact both staggered, batten on board to sew, and a slight overlap and orifice plate strip. Crack area is determined according to gas velocity. In the treatment of the thick fog particles of low pressure drop in the separator, the area of the plate and compared to the cross-sectional area of the gas pipeline can be quite large. At this time can put the plate component arranged in V in order to prevent the fog particles of arrest set has to return to the air, it must be installed on the downstream side of the main board piece capture board. General return airflow of fog particles coarser, therefore can capture board design into the form of a low pressure drop, the crack area of not less than the impact on a board to sew area. Capture board crack width for 2 on the impact plate. Five times, through the pressure plate capture 20% of the loss about the main thing. Orifice plate and impact plate spacing within a certain range between the performance impact is not big, but the plate spacing congress have an adverse effect. Such as spacing is less than half a hole seam strip width, pressure drops. Generally preferable plate spacing is equal to the slit width of orifice plate. Plate spacing and hole seam strip width with 1 commonly. 5 mm is the minimum value. If the gas load exceeds a range of change, the separator should be according to the highest gas flow design. In low flow runtime, using the hole on the cover plate to reduce the orifice area, to keep the gas velocity is constant. Can clip on the upstream face of orifice plate. If the gas containing solid particles, which may be blocked and can be installed upstream of the nozzle, the mainboard flush on a regular basis. Separator should be paid attention to during the operation, the pressure drop of whether to keep normal value. Such as abnormal high numerical description to sew may partially blocked; While a low value, sign boards can be out of shape, or slit system for leaks.
