The Working Principle of Desilter

Posted by:    Time:2014-02-22     click:

Cyclone bed cleaning device is the use of the working principle of centrifugal separation for bed cleaning, owing to the eccentricity of the inlet pipe installed in cylinder position of the main parts. After the rotation flow bed cleaning by water inlet pipe, first along the tangent direction around the cylinder form fluid around the inclined downward, rotating flow goes down. When the water reaches a portion of the cone, and along the axis of cylinder rotate upwards, finally through the outlet pipe discharge, noise pollution in fluid inertial centrifugal force and under the action of its own gravity with using desilter and desander. The cone bottom cinder cone bucket wall into the equipment, the cone bottom is equipped with components to prevent clutter up flush, when accumulated clutter in the slag bucket to a certain degree, as long as the open manual butterfly valve, clutter can be under the effect of water flow cyclone bed cleaning device.

Cyclone desander is based on the working principle of centrifugal sedimentation and density difference, as the water under a certain pressure from desanding inlet to tangential into the equipment of desilter or desander. A strong rotation movement, as the density of sand and water is different, the centrifugal force, centripetal force, buoyancy and fluid drag force, under the joint action of the water of the low density increased. Due to the discharge outlet at the bottom of the equipment, the dense sand achieves the aim of sand.

As the water under a certain pressure from desanding inlet to tangential into the equipment of desilter and desander, a strong rotation movement. Because of the density of sand and water is different, the centrifugal force, centripetal force, buoyancy and fluid drag force, under the joint action of the water of the low density increased, by the discharge outlet, dense sand due to the discharge outlet at the bottom of the desilter equipment. So as to achieve the aim of desanding, have high sand ratio, save installation space, to individual tiny solid leak rate is low, stable working status and so on.

In a certain scope and conditions, the desander feed water pressure, the greater the desanding rate is higher, and can be used more than one parallel.

Raw water filtration tank - user cyclone desander is based on the working principle of centrifugal sedimentation and density difference, as the water under a certain pressure. To tangential into the equipment imported from desilter and desander, after an intense feeling of rotary motion, because sand water density is different, the centrifugal force, the centripetal buoyancy and fluid drag force due to the stress under the action of different. So that the low density of water rise, of the overflow mouth eduction, dense sand is being exhausted from port on the bottom row of sand, so as to achieve the aim of sand.
