2. The inside anticorrosive coating of dust collector establishes to unevenness's surface, has broken through the surface and has been planar conventional operation, because the main object of dust collector internal work during is dirt gas, if the surface is the plane, has certain vector's dirt gas direct action on the plane, and the plane atress is great, and the osmotic force is big, if adopt unevenness's surface, and the effort is dispersed when dirt gas acts on the surface, and the osmotic force weakens relatively, can be less the corruption that gas permeation produced.

3. The box of dust collector sets to bilayer structure, leaves the clearance of certain distance between outer box and the interior box, because the coefficient of heat conductivity of air is very low, consequently can play the heat preservation effect, prevents that the inside and outside difference in temperature is great to lead to the individual position to produce the comdenstion water and cause the corruption to the box structure, and clearance control is in certain extent, and the clearance is too narrow to be difficult to play the heat preservation effect, and the clearance is too big not only can influence equipment stability, still can cause pressure for interior box outer wall too much dispersion heat. The outer box body is also provided with a switch valve which can be opened or closed, after the equipment works for a long time, the pressure intensity is increased inevitably due to excessive heat conduction in the gap, the pressure intensity can be recovered to the normal pressure by opening the through hole, and meanwhile, when the equipment stops working, the heat dissipation effect can be achieved. The dust collector combines outside protection, intermediate level heat preservation and inside anticorrosion, to equipment structure's corruption and destruction, has saved production and running cost greatly when effectively having avoided the long-time operation of dust collector.
