Circulating blowdown device for seawater treatment

Abstract

The invention provides a circulating blowdown device for seawater treatment, and belongs to the technical field of seawater treatment equipment. The circulating blowdown device for seawater treatment comprises a first filtering mechanism and a chemical mixing mechanism. The first filtering mechanism comprises a base, supporting legs, a filtering cylinder, a first pump body, a first water conveying pipe, a second water conveying pipe, a first water outlet pipe, a first valve and a first filtering assembly. The chemical mixing mechanism comprises a reaction cylinder, a first supporting piece, a driving piece, an auger, a second pump body, a third water conveying pipe and a fourth water conveying pipe. The reaction cylinder comprises a cylinder body, a chemical feeding pipe, a fifth water conveying pipe and a second valve. According to the device, the inner wall of the cylinder body and the auger can be directly flushed in the one circulation process after seawater treatment is completed, the device does not need to be opened for manual cleaning, and the cleaning efficiency is greatly improved; and meanwhile, a first filter screen on the used first filtering assembly can be cleaned or replaced under the conditions that the machine is not stopped and the normal filter function of the device is not influenced.

Description

technical field [0001] The invention relates to the technical field of seawater treatment equipment, in particular to a circulating sewage discharge device for seawater treatment. Background technique [0002] With the continuous advancement of marine high-tech, human beings will continue to deepen and expand the development, utilization and protection of the ocean, and marine information services and marine environmental protection will become new industries. Seawater desalination and comprehensive utilization of seawater are developing industrially. At present, the easiest way to treat seawater is to initially filter out large particles of impurities, then use a treatment agent to precipitate and precipitate, and then filter again to complete the treatment. [0003] Existing seawater treatment equipment cannot directly clean and replace filter components without stopping the machine and ensuring the filtering function, and can only be carried out when the equipment is shut...
