l 1) Non contact dust removal
l adopt the non-contact dust removal method of high-pressure ion wind, which has good dust removal effect, high efficiency and high cost;
l When the electrode passes through the inlet end of the cleaning head, the ionization cloud here and the static electricity on the coil surface are removed;
l Then, the electrode is affected by the turbulent air flow generated by the internal blowing and vacuum air flow of the cleaning head device；
