Abstract

The invention relates to water treatment equipment, in particular to a cavitation device used for treatment of ship ballast water. A water treatment device based on a self-excited oscillating cavitation impeller, comprising a stationary impeller and a moving impeller; several helical tooth structures are provided on the surface of the stationary impeller opposite to the moving impeller, and cavities are formed between the helical tooth structures; A number of tooth-shaped structures are provided on the surface of the moving impeller opposite to the stationary impeller, and a first oscillation cavity is provided between the tooth-shaped structures. The device of the present invention utilizes a stationary impeller with a surface-etched micro-venturi tube structure and a moving impeller with a self-excited oscillation cavity structure. During the rotation of the moving impeller, a high-strength cavitation is formed between the two impellers, and the cavitation is utilized to The generated high temperature, high pressure and strong mechanical action kill algae and microorganisms to achieve the purpose of water treatment.

Description

technical field [0001] The invention relates to water treatment equipment, in particular to a cavitation device used for treatment of ship ballast water. Background technique [0002] As we all know, most of the international trade is dominated by ocean shipping. According to statistics, 80% of the transportation volume in international trade is carried out by sea transportation. When the ship is empty and full, the position of the waterline will change. In order to ensure the safety and economy of the empty voyage, it is necessary to fill part of the ballast tank of the ship with water to maintain the waterline during the empty voyage. [0003] For ships that are empty or under a light load, it is necessary to ensure the depth of the propeller into the water and ensure safe navigation when empty, so the water (sea water, lake water or river water) in the port is taken to pressure before leaving the port. tanks to serve as ballast water. [0004] Ship ballast water contai...
