Based on the electromagnetic force iron removal technology, 1 early steel ball type electromagnetic filter, to the later steel wool type electric filter, self cleaning filter, is currently used in high gradient electromagnetic filter with scroll steel and wool composite matrix as filler. In this high gradient electromagnetic filter, there are dozens of microns of wire diameter scroll steel magnetic material, so when the excitation coil is connected with direct current, it will soon be magnetized and form extremely high magnetic gradient in the gap of magnetic filler. Because this filter can generate large magnetic force, it can not only remove ferromagnetic particles in water, but also greatly increase the ability of removing paramagnetic particles in water.
magnetic filter is a filter that uses the effect of electromagnetic force to remove magnetic oxide in water. The structure of the current high gradient electromagnetic filter is made of non-magnetic material, and the cylinder is surrounded by the exciting coil, which is filled with magnetic material in the core.
The iron removal process is the electromagnetic filter, self cleaning filter coil connected to DC electric current to generate directional magnet when the condensed water is processed from top to bottom through the filler layer is magnetized when the metal corrosion particles of iron in water by cleaning the filter magnetic filler absorb and remove.
