Electromagnetic Rapping Systems

Discharge electrodes, collecting plates and gas distribution devices are subject to particulate build-up during normal precipitator operation.  When build-up is allowed to occur, electrical clearances are compromised and distorted air flow patterns develop.  Reduced electrical clearance and distorted air flow are primary causes for an ESP losing performance efficiency.

SEI rapper systems have been specifically developed and tested for continuous removal on a wide range of ash types. The key to SEI’s success is programmable controlled rapping, utilizing the most durable equipment.

The SEI electromagnetic rapper is engineered for use with rigid discharge electrodes and collecting plates.  The coil is epoxy encapsulated which ensures long life and maintenance free operation.  The system is microprocessor based and designed for maximum service life and easy operator interface.

Collecting Plates

SEI furnishes both segmented and one-piece collecting plates.  Experience has shown that these types of plates are mechanically, structurally and aerodynamically the best plates for a precipitator.  Structurally, they stand up well to heavy repeated rapping.  Their roll formed designs resist bowing and resultant misalignment due to temperature and rapping.  When properly rapped, the collected dust is effectively sheared from the plate over its entire length and falls into the collection hopper with minimum re-entrainment.

ELEX Discharge Electrodes

SEI ELEX Discharge Electrodes are virtually unbreakable and not subject to electrical erosion or mechanical wear – the principal causes of discharge electrode failure.

Improved Cleaning Effect

The vibrations set up by the rapping system are transmitted over the entire length of each and every electrode.

Optimum Electrostatic Design

The corona discharge is guaranteed at every point because the points are geometrically disposed throughout the whole effective column of the precipitator.  The excellent corona effect ensures optimum charging of particles and a superior – constant cleaning efficiency.

No Bending or Distortion

The lower guide frame ensures that the Rigid Electrode will not bend or deform, even when subjected to excessive variations of temperature in the precipitator.

Longest installed electrode is 50 ft.

FreeFlow-188

FreeFlow-188 is a non-ionic drainage aid designed to improve and increase water removal during the
filtering process. FreeFlow-188 is compatible with weak wash, white and green liquor. FreeFlow-188 is the
ideal product for increased Kiln fuel savings, increased Kiln production, and improved Pre-coat filter
performance. FreeFlow-188 has been proven to effectively increase solids over the lime mud Pre-coat filter and does not
foam above 100F.

Vacuum / Drum Filter Drives

DBS makes bolt-in replacements for drum filter drive units. These retrofits can put a more economical and more rugged DBS drive to work in your plant performing these important functions. Like all DBS products, these retrofit drive units are covered by exceptional warranties and our 24-hour “engineer on call” service.

DBS vacuum or drum filter drives are designed to operate in rugged, demanding industrial applications such as in pulp & paper plants, chemical processing plants and alumina. DBS drives use steel spur gears, not bronze worm gears, and heavy-duty precision bearings for long life and reliability. These DBS drives typically are a “hollow-bore” design to allow vacuum, steam, or process lines to go through the drive and into the filter drum.

Rotating Biological Contact Drives

DBS manufactures custom drives for applications such as flocculators, mixers, vacuum filters, rotating biological contact units, and other industrial applications.

DBS makes bolt-in replacements for rotating biological contact units. These retrofits can put a more economical and more rugged DBS drive to work in your plant performing these important functions. Like all DBS products, these retrofit drive units are covered by exceptional warranties and our 24-hour “engineer on call” service.

DBS drives can replace the drives on Autotrol, Walker Process and other manufacturers’ rotating biological contact units. DBS drive units are hydraulically driven, permitting high-torque low-speed starting, which is particularly useful in getting the disks moving when initially they are out of balance. The hydraulic drive operates with low power, and one central power source can drive multiple disks. Lower operating cost and longer life are what you can expect from DBS drives.

Horizontal Flocculator Drives

DBS manufactures custom drives for applications such as flocculators, mixers, vacuum filters, rotating biological contact units, and other industrial applications.

DBS makes bolt-in replacements for flocculator drive units. These retrofits can put a more economical and more rugged DBS drive to work in your plant performing these important functions. Like all DBS products, these retrofit drive units are covered by exceptional warranties and our 24-hour “engineer on call” service.

DBS horizontal flocculator drives are rugged integral units that can be submerged for short periods of time without damage to the drive unit. These units are usually supplied with variable speed capabilities to fine tune the speed of rotation of the flocculator paddles. These units are provided for new installations and for upgrading and modernizing existing installations.
