Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a seawater filtering device. Background Art

[0002] With the global shortage of freshwater resources, seawater desalination technology has become an important way to solve the problem of water shortage. However, during the desalination process, impurities such as suspended matter, microorganisms and dissolved salts in seawater will affect the efficiency and life of desalination equipment.

[0003] According to the application number (CN202411017313.8), a seawater desalination pretreatment filtration device is disclosed, which relates to the field of water treatment technology, including a high-pressure pump, a dosing tank connected to the high-pressure pump, and a coarse filtration unit and a fine filtration unit, and also includes: a water quality detection unit, the water quality detection unit is arranged on the outlet pipe of the fine filtration unit, and the outlet pipe below the water quality detection unit is divided into two branch pipes with a solenoid valve; an auxiliary filtration unit, the auxiliary filtration unit is arranged on one of the pipes; a cleaning unit, the cleaning unit is installed in the coarse filtration unit and the fine filtration unit, the cleaning unit includes a cleaning pipe densely covered with nozzles and a plurality of cleaning disks arranged on the cleaning pipe, and the cleaning pipe is externally connected to high-pressure water vapor. The present invention can automatically adjust the treatment process according to the water quality conditions to ensure that the outlet water quality meets the preset standard, providing a good prerequisite for subsequent seawater desalination treatment. At the same time, the existence of the cleaning unit also greatly extends the service life of the filtration equipment and improves the operating efficiency of the equipment.

For example, when cleaning impurities in the filter mesh and activated carbon, although the reverse osmosis cleaning method can clean out most of the impurities, the cleaning effect is general and cannot achieve the desired cleaning effect. Some fine suspended matter, microorganisms, dissolved salts and other impurities will remain in the filter mesh and activated carbon, which will greatly reduce the filtering effect of the filter mesh and activated carbon. At the same time, a large amount of impurities will also be adsorbed on the inner wall of the filter tank, which will greatly reduce the service life of the filtration equipment and the operating efficiency of the equipment.

[0005] In order to solve the above problems, this application proposes a seawater filtration device. Utility Model Content
