(CI‐WT)DS system is a plain filtered water air high pressure Dust Suppression system. (Application) Wagon Tippler (coal) normally installed near the entrance to the unloading bunkers. Principle of Operation:‐ The pump is to be activated manually (optional auto system if required) spray will activate automatically once the wagon tippling required) spray will activate automatically once the wagon tippling action starts in the WT‐MCC. The WT‐discharge actions in the MCC switch to energize the normally closed solenoid valve. (area defined for actuating spray under ground) and passes water line across the solenoid valve to the pre located sprays This is set to a timer for continuation of spraying and will cut is set to a timer for continuation of spraying and will cut off after a timed period (set by timer). The sensor switch system installed in the WT‐MCC is interlocked with the wagon tippler operation. (Optional‐PRE‐WETTING‐MANUAL) The FOG JET nozzle spray fitted on the entrance of the receiving pit area will spray to moisten the top layer at the wagon (Optional‐ Automizing) Further in order to form a water curtain around the entire periphery specially designed atomizing can be installed & activated at the same time with an extra high pressure small discharge pump (nozzle discharge 0.3 lpm @ 70‐100 bar pressure) Dust generating points will be properly placed with spray headers and nozzles which produce fine mist sprays. The Air borne dust oncoming in contact with the fine mist type water il hi h b h d l d ih h The water consumption and humidifying of the materials is reduced, with negligible discharge per nozzle on DUST SUPPRESSION SYSTEM particle, which becomes heavy and settle down with the original material flow. negligible discharge per nozzle on material transported. Client will provide electric & water connection as required. Typical Applications:‐ • Dust Suppression system for Wagon Tippler / Track hoppers dust suppression & allied equipments
