Reasons:
1. Insufficient sediment: If there is insufficient sediment during the use of the horizontal centrifuge, the effluent water will be turbid. It may be due to the accumulation of too many impurities on the filter net in the centrifuge, resulting in a decrease in the filtration effect; or there are too many floating particles in the raw liquid entering the centrifuge, resulting in a decrease in the separation capacity of the horizontal centrifuge.
2. Operational errors: Frequent opening and closing of the water inlet and outlet valves during the filtration process will destroy the separation balance in the centrifuge and cause turbid effluent water. In addition, if the operator fails to add the raw liquid entering the centrifuge to the sedimentation tank in time, or uses incorrect filter media, it may also cause turbid effluent water.
3. Equipment failure: If the centrifuge speed is too fast or too slow, the bearing is worn, etc., it may affect the centrifugal process and cause turbid effluent water. In particular, when the screw conveyor is severely worn, it will affect the separation effect of the same liquid.
4. Problems with the amount of mud or speed: If the amount of mud is too large, the speed difference is too large, and the solid overload of the flow of people, etc., it may also cause the supernatant to be turbid, thereby reducing the solid recovery rate.
Solution:
1. For the problem of insufficient sediment, the filter screen and sedimentation tank should be checked, cleaned regularly, and an appropriate amount of sediment should be added to improve the filtration efficiency.
2. For operational errors, operators must strictly follow the standard operating procedures to ensure that the original liquid is fully precipitated before entering the centrifuge for filtration.
3. For equipment failure, the centrifuge equipment should be regularly inspected and maintained to ensure its normal operation. If equipment failure is found, timely repair or replacement of parts, such as replacement of worn screw conveyors, etc.
4. For the problem of mud inlet or speed, you can try to reduce the mud inlet, adjust the speed difference, replace the appropriate screw conveyor or increase the drum speed. In general, the solution to the problem of turbid clear liquid in the horizontal screw centrifuge needs to comprehensively consider multiple factors such as equipment, operation, and maintenance to ensure the normal operation of the equipment and timely maintenance of the operation specifications. If the problem persists or worsens, it is recommended to contact a professional maintenance team for further inspection and repair.
