Wide spacing electrostatic precipitator is one of the most efficient dust collectors currently available. In the 1950s, the Germans in Europe first discovered the wide spacing dust removal technology, but failed to obtain practical progress. In the 1970s, energy scarce Japan made significant contributions to the research, application, and development of wide spacing electrostatic precipitators by strengthening environmental protection and energy conservation. In earlier years, there was still controversy and denial about wide spacing dust collectors internationally, until it was unanimously recognized and acknowledged by attending experts and representatives at the Second International Conference on Electrostatic Precipitation held in Kyoto, Japan in November 1984. At present, countries are developing and testing wide spacing electrostatic precipitators, and a "wide spacing" trend is emerging, which will replace conventional spacing electrostatic precipitators.
The so-called "wide spacing" refers to the electrode spacing of the dust collector being greater than 300mm, specifically referring to the electrode spacing of 400mm or more.
scope of application
The CDPK-10/2 type is suitable for a Ø 2.8 × 14m rotary dryer (downstream or upstream), and the H grade is specifically designed for corrosion-resistant dryers;
CDPK-10/2 type small hollow dry rotary kiln with a diameter of 1.9/1.6 × 36m, CDPK-30/3 type five stage preheating rotary kiln with a diameter of about 2.4/1.6 × 44m, and CDPK-45/3 type, suitable for use in two sets of rotary kilns with a diameter of about 4.0/60 vertical tube or four pairs of preheaters;
CDPK-67.5/3 type is suitable for producing 700td/d pre decomposition rotary cellar with a diameter of 3. O × 48m;
CDPK-90/3 type is suitable for pre decomposition rotary kilns with a production capacity of 1000t/d for a diameter of 4 × 60m;
The CDPK-108/8 type is suitable for large rotary kilns. When the CDPK series is used for wet or rotary kilns, corrosion resistance measures are considered in the structure.
