RAPSCAN is a compact advanced microcontroller based rapping sequential timer used in electrostatic precipitator, which is an air pollution control device. To improve collection efficiency and ensure proper functional use of the precipitator for a clean Environment in atmosphere. A complete ESP set up of a rapping system is applied to the collection plates and electrodes to dislodge the collected dust layer. In the next stage it is handled by Bag filters. A falling weight or fixed rotating hammer controlled by the rapping timer raps the collection plates, causing vibration that knocks off the dust layer from the collecting electrodes.
The parameters available in RAPSCAN are programmable via four key pad assembly. All programmed values are stored permanently in non-volatile memory. Intelligent program lock (Password protection) is provided so that set parameters cannot be tampered by unauthorized persons. Skip function is realized by setting zero repeat time to switch off unused channels. The main block modules are Automatic mode and Manual Mode of operation for user convenience. The real time setting & program numbers storage facility for multiple programs retentions are available by EEPROMS. The communication facility extended using Rs485 link for Scada or plc for further processing of data.
