0529 Improvement of poor outflow of sludge incineration ash

Resolved issues where insufficient remaining contents in the silo caused discharge failures, preventing truck loading!

We have been adopted for a project aimed at wastewater treatment plants by a customer related to plants. The subject matter is sludge incineration ash, and the issue was that "when the remaining amount of silo contents decreased, discharge failures occurred, making it impossible to load onto trucks (troubles occurred when the remaining amount was below 20-30 tons)." Previously, a mesh-type air rater was used, and although the air pressure was increased, it did not lead to improvements, resulting in mesh damage and air leaks from the surroundings (other aeration methods were also used in conjunction). Therefore, although it is a large silo, the trouble only occurs when the powder level decreases. We positioned the equipment in three tiers near the discharge area (only the three tiers below the silo, without the fourth and fifth tiers). There are a total of 20 standard type blow discs: 4 in the bottom tier, 8 in the second tier, and 8 in the third tier. Control is managed by a controller with 10 solenoid valves built-in. The operating air pressure is set higher, and we addressed the issue by turning on the air in small increments (2 units at a time). *For more details, please refer to the PDF document or feel free to contact us.
