TH16A3 - Sludge layer sedimentation tank using a hydraulic system of water to pulsate the sludge. - Google Patents

Abstract

The Sludge Blanket Clarifier relies on the flow of water to make the sludge layer uniformly dense (Uniform Sludge Concentration) by storing raw water in the Header Compartment to the desired level. It causes the water in the water storage section to flow quickly into the water ripple section by lifting the water transfer pipe cover up with the Lifting Device, which receives the signal from the level switch. The water in the water ripple section. It flows into the sludge layer in the sedimentation tank through the perforated pipe, causing the sludge layer to ripple and arranged in a uniform density (Uniform Sludge Concentration) for high efficiency sedimentation. When the water in the water tank drops to the lowest point The water level measuring device signals the pressure lifter of the water transfer pipe cover. The ripple stops and the water begins to accumulate in the new water reservoir to the desired level, and the water is transferred and the water is stopped. Continuously alternate The sludge layer in the sludge is always dense. This makes the sedimentation of the sludge layer highly efficient.

Claims (4)

1. SLUDGE BLANKET CLARIFIER, which is characterized by a sedimentation component. It is a tank and has a water chambers (RIPPLE WATER CHAMBER) 3 in place to allow water to be released into the sediment layer. The water ripple tower is divided into 2 parts with 4 dividing plates, the upper part is the water storage (HEADER COMPARTMENT) 5, the lower part is the water ripple (RIPPLE WATER COMPARTMENT) 6. The top 5 siphon is open to the atmosphere. (In the event that the top cover is completely closed, ventilation ducts must be made) The lower water ripple 6 is opened to the atmosphere with the vent pipe 7 according to Figure 5, raw water flows into the water reservoir by raw water pipe 1 due to the ripple water transfer pipe ( RIPPLE WATER MAIN PIPE) 9 is closed (COVER PLATE) 10 is closed, the water in the water tank will gradually rise up to the water level at point 17 according to Figure 6, at this point according to Figure 7, level measuring device (LEVEL SWITCH). 12 at level L 1 is complete and sends a signal to the lifting device (LIFTING DEVICE) 13 works, pull the lever (LIFTING SHAFT) 11 up, the lever 11 will pull the cover (COVER PLATE) 10 up, so the water inside the water tank Will flow rapidly into the main pipe, water ripple 9, which can adjust the flow of water flowing in the pipe by adjusting the opening distance 10 with the adjusting rod (FLOW CONTROL SHAFT) 14, which will be adjusted up or down by the steering wheel. (HAND WHEEL) 15 To adjust the opening of the lid 10, it can adjust the water ripple towards the sludge layer to be strong or gently to suit the density of the sludge. When the water level in the water tank drops to level 11, the level 12 measuring device at level L 2 completes the loop, sends a signal to the lifting device 13 to work, push the lever 11 down to the lid 10, close the ripple water transfer pipe. 9 Water in The water collector stops flowing into the water ripple section and begins to rise to level 17, the water level meter 12 is complete and sends the lifting device 13 to work. Lift the cover 10 to let the water in the water tank flow. Into the water transfer pipe 9 to continuously ripple the sediment layers alternately as long as the raw water flows into the water reservoir. In case of need, stop the sediment flow for a long period as required. Do this by closing the lid on 10 until the set time is reached. Therefore, the lifting device 13 is operated, during which the water in the water reservoir will overflow the overflow drain 7 into the ripple section instead of the water transfer pipe 9. 2. Sedimentation tank according to claim 1, where the position of the water ripple tower can be set both inside and outside the sedimentation tank. 3. Sedimentation tanks according to claim 1, where the water storage (HEADER COMPATEMENT) and the water ripple (RIPPLE WATER COMPARTMENT) can be installed separately. There is a ripple water transfer pipe (RIPPLE WATER MAIN PIPE) between the two parts. 4. The sedimentation tank according to claim 1 is also equipped with an additional pump for pumping water into the water reservoir (HEADER COMPARTMENT) to create a continuous water ripple in the event that raw water is not pumped into the sedimentation tank.
