Description

Technical Field

[0001] The utility model relates to the technical field of water system filtration, in particular to a filter adjustment system. Background Art

[0002] In the production process of the coking industry, the effective operation of the water system plays a vital role. It is directly related to the stability of product quality, the improvement of production efficiency and the effectiveness of environmental protection. Among them, water system filtration, as a key link in purifying water quality and removing suspended matter and impurities, usually adopts shallow sand filtration system as the mainstream technology. This system is widely used for its simple structure, convenient operation and certain filtration efficiency. However, with the continuous advancement of coking technology and the expansion of production scale, the requirements for water purity are also increasing, and the traditional shallow sand filtration system has gradually exposed its limitations. Specifically, during the use of the filter, the filter material layer is blocked due to long-term operation, which affects the filtration efficiency and flux. At this time, regular backwashing operations are required to restore its filtration performance. For example, the Chinese patent with the authorization announcement number CN211051031U discloses a filter backwashing device for a sewage treatment station, which performs secondary filtration on the water filtered by the backwash filter by setting a filtering device to achieve an efficient filtering effect. Unfortunately, the existing backwashing mechanism often has problems such as insufficient flushing intensity and uneven distribution, resulting in poor backwashing effect and inability to completely remove the accumulation in the filter material layer, thereby limiting the continuous and efficient operation of the filter. This deficiency directly affects the water quality of the coking process water, increases the subsequent processing costs, and may even affect the stable operation of the production line due to substandard water quality, and cannot meet the increasingly stringent production needs and environmental protection standards. In view of this, the development of an efficient filter adjustment system has become an important research direction for the optimization and upgrading of the water system in the current coking industry.

The pipeline pump 4 is arranged between the user end 3 and the shallow sand filter 1, and circulating water and cooling water flow into the shallow sand filter 1 through the pipeline pump 4. The cooling tower 6 is arranged between the pump room 2 and the shallow sand filter 1, and the pneumatic butterfly valve 5 is arranged between the cooling tower 6 and the shallow sand filter 1. By arranging the pneumatic butterfly valve 5, the pipeline outlet is opened and closed according to the backwashing time, the pressure inside the shallow sand filter 1 is increased, and the backwashing effect is improved.

[0020] As a further solution of the present application, the user end 3 is connected to the input end of the circulating water pipeline and the cooling water pipeline, and the output end of the circulating water pipeline and the cooling water pipeline is connected to the shallow sand filter 1.

[0021] As a further solution of the present application, the pipeline pump 4 has a head of 40 meters and a flow rate of 500m3 / H. The pipeline pump 4 is provided to increase the pressure of water entering the shallow sand filter 1 and improve the backwashing effect.

[0026] Working principle: When in use, the system receives circulating water and cooling water from the user end 3. These two water flows enter the system through their respective pipes. Before entering the shallow sand filter 1, the circulating water and cooling water are first pressurized by their respective independent pipe pumps 4. These pipe pumps 4 ensure that the water flows into the shallow sand filter 1 with sufficient pressure and flow for effective filtration treatment; the circulating water and cooling water pressurized by the pipe pump 4 flow into the shallow sand filter 1, and in the shallow sand filter 1, the water flows through the sand layer for backwashing to remove suspended matter and impurities, thereby improving the water quality; after the filtration is completed and the water quality meets the standard, the PLC controls the pneumatic butterfly valve 5 to open, and the circulating water and cooling water are mixed and flow into the cooling tower 6, and the cooling tower 6 cools the water, and finally the cooled water flows into the pump room 2 and continues to be transported to the user end 3.
