Design issues for the outlet at the bottom of the sedimentation tank

Thread Content

Design issues regarding the outlet at the bottom of the sedimentation tank: 1. Our company has designed an outlet at the bottom of the sedimentation tank; however, this design causes problems in production. The reason is that fluctuations in the quality of the raw coal lead to variations in the suspended solids content in the black water within the system. When the suspended solids content is too high, the outlet pipeline at the bottom of the sedimentation tank will become clogged over time as the system operates. Once this pipeline becomes blocked, solid particles will be carried throughout the water system, causing scaling and blockages in other equipment and pipes; in severe cases, operations have to be halted, affecting production. 2. The bottom of the sedimentation tank is designed with two outlets, and flushing water is provided at these outlets; it is recommended to adopt this design as it is more reasonable. Please give me some advice. This post was last edited by Tianya Langji on 2009-3-11 at 12:09 [Font size & title]
