Description

Pipeline energy-saving sludge dewatering system

The present invention relates to a water eliminator, in particular to a pipeline type energy-saving sludge water removal system.

As shown in Figure 1, a conventional sludge dehydration system for industrial wastewater treatment includes a concentration tank 1 located downstream of a flotation tank (not shown), and a sludge pump connected to the concentration tank 1. 2. A conveying pipeline 3 connected to the sludge pump 2, a belt dehydrator 4 located at the end of the conveying pipeline 3, and a sludge collector that can receive the sludge discharged by the belt dehydrator 4. Dou 5.

Generally speaking, in the current industrial wastewater treatment process, after the wastewater is quickly mixed with a coagulant aid and the sludge (gelatin scum) is scraped off by the flotation tank, due to the high moisture content of the sludge, it is still The sludge must be further transported to the concentration tank 1 to allow the sludge to settle in the concentration tank 1 to reduce the gaps between the rubber feathers and increase the concentration so that the moisture content of the sludge can be reduced to about 95%. After that, The sludge pump 1 can transport the sludge to the belt dehydrator 4 through the transport pipeline 2 to further remove the moisture contained in the sludge and further reduce its moisture content to about 86%. Among them, the flotation tank scrapes the water contained in the scum. The moisture content of the sludge when it is removed from the concentration tank 1 can be affected by the settling time of the concentration tank 1 and the quality of the coagulation and settling effect.

In the process of sludge transportation in this kind of sludge dehydration system, the sludge pump 2 is generally used to pressurize the sludge from the concentration tank 1 located in the outdoor treatment field to the indoor through the transportation pipeline 3. During the transportation process of the belt dehydrator 4 through the transportation pipeline 3, although the transportation distance is very long, the moisture content of the sludge will not decrease during the transportation process. In addition, due to various Both the transfer pump (such as the sludge pump 1) and the dehydrator (such as the belt dehydrator 4) are energy-intensive equipment and require manpower to operate. Therefore, the operating cost of this sludge dehydration system is high.

During this process, the return valve 420 of the respective return water pipeline unit 400 can be used to adjust the amount of backwash water, and , the user can also choose to open only a certain return water valve 420 or some return water valves 420 to backwash a certain section or sections of each water removal pipeline unit 100. After that, the backwash flows into each water removal pipeline unit 100. The end drain eliminator 60I and the intermediate drain eliminator 60II of the water pipeline unit 100 can remove the sewage in the internal space 131 of the water body 10 through the first input pipeline 610 and the second input pipeline of the input pipeline unit 600 One of 620 and the discharge pipe 710 and the discharge valve 720 of the respective discharge pipe unit 700 are discharged into the original waste water tank.

In this way, in addition to achieving the same purpose and effect as the above-mentioned first embodiment, the second embodiment utilizes the return pipeline units 400 to cooperate with the backwash pipeline units 500 and the input pipe. The design of the pipeline unit 600 and the discharge pipeline units 700 can also backwash the water removal pipeline units 100 to clean the water removal pipeline units 100. The backwashing operation is simple and the operation cost is low.

In summary, the pipeline-type energy-saving sludge dewatering system of the present invention not only allows the sludge to filter out water while flowing, but also can effectively reduce energy consumption and operating manpower, thereby reducing operating costs, and can also The waste water is collected and discharged to the original waste water tank, so the purpose of the present invention can indeed be achieved.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made based on the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention. Within the scope covered by the patent of this invention.
