szs engineering provides the full range of services for your WESP revamp project, from engineering, via supply, dismantling and erection through to commissioning and after-sales service.
Our revamp services for existing WESPs
include the re-lining of the existing precipitator casing, the installation of new discharge and collecting electrodes as well as new high-voltage transformer-rectifier sets while maintaining the existing infrastructure.
Replacement of various wet electrostatic precipitator components like:
- Replacement of collecting electrodes, conversion from pate, single tube or honeycomb systems to compact thermoplastic tube bundles
- Replacement of discharge electrodes
- Replacement of upper and lower discharge electrode support frames
- Repair of casing lining
- Replacement of high-voltage unit and precipitator controls
- Conversion of the insulation system (e.g. dry insulator, air-purged insulator, steam-heated insulator)
- Replacement of precipitator grounding system
The ESP internals are available in all common materials used in the specific applications such as the chemical industry
, power plants
, municipal waste incineration plants
, steel industry
, CO gas applications
as per the applicable regulations.
For special applications such as CO gas cleanup, the electrostatic precipitator components will be designed to meet the requirements of AD2000 /PED 97/23, ATEX 100a, EEx zone, with conformity declaration according to ATEX Directive 94/9/EC and conformity certificate issued by TÜV.
