Embodiment 1

[0038] see figure 1 and figure 2, the anti-scaling technology and device of the filter used in the ship's ballast water management system of the present invention include a coarse filter screen 2, a fine filter screen 3, a backwash unit, a sewage discharge unit and a control system 25, which are installed horizontally in the filter cavity Coarse filter 2, first partition 15, fine filter 3, another partition 16, sewage unit; control unit is part of the main control equipment; first partition between fine filter 3 and coarse filter 2 15 and the filter chamber form a filter chamber 4, the water inlet 1 is installed on the filter housing 26 above the coarse filter 2 and communicates with the filter chamber, and the water outlet 5 is installed on the filter housing 26 and communicates with the filter chamber 4 ; Also includes a frequency conversion electromagnetic processing unit, the frequency conversion electromagnetic processing unit is composed of a signal generator controlle...

Embodiment 2

[0070] The method for filtering using the anti-scaling device of the filter for the ship ballast water management system of embodiment 1 of the present embodiment includes:

[0071] 1) The step of carrying out two-stage filtration to the ballast water: the ballast water is firstly filtered through the coarse filter screen, and then flows into the fine filter screen for the second-stage filtration;

[0072] 2) The step of flushing the fine filter: using the sewage nozzle and the sewage cavity to flush the fine filter;

[0073] 3) The step of using the sewage unit to discharge the sludge in the device;

[0074] Also includes:

[0075] 4) The step of using the frequency conversion electromagnetic treatment unit to perform electromagnetic treatment on the water in the fine filter: changing the arrangement of water molecules to prevent scaling;

[0076] 5) The step of using the ultrasonic unit to perform sonic treatment on the whole set of equipment: remove the dirt on the surfac...

Abstract

The invention discloses an anti-scale method and device of a filter used in a ship ballast water management system. The device comprises a coarse filter screen, a fine filter screen, a back-washing unit, a sewage discharge unit, and a control system; the coarse filter screen, a first partition plate, the fine filter screen, another partition plate, and the sewage discharge unit are horizontally arranged in the filter cavity; a control unit is part of main control equipment; the first partition plate between the fine filter screen and the coarse filter screen and the filter cavity form a filtering cavity, a water inlet is arranged on the filter shell, is above the coarse filter screen, and is communicated with the filter cavity; and a water outlet is arranged in the filter shell and is communicated with the filtering cavity. The device also comprises a variable-frequency processing unit, which is composed of a signal generator controlled by the control system and electromagnetic coils, and the electromagnetic coils are winded around the coarse filter screen. The provided anti-scale method and device solve the problem that conventional ship ballast water filter is easily obstructed during the application process, and the anti-scale device has the advantages of high integration level, small volume, and high intelligentization degree, and can meet the application requirements of a ship ballast water management system.

Description

technical field [0001] The invention belongs to the technical field of marine engineering equipment, and in particular relates to a scale prevention method and device for a filter used in a ship's ballast water management system. Background technique [0002] During the voyage of ocean-going ships, ballast is an inevitable state. Off-site loading and discharge of ballast water can cause the spread of harmful aquatic organisms and pathogens. In order to control the hazards of ships' ballast water, the International Maritime Organization (IMO) has formulated the "International Convention for the Control and Management of Ships' Ballast Water and Sediments". At present, the mainstream technology of ship ballast water management system can be mainly divided into physical separation method (invention patent 201280007040.8), irradiation method (invention patent 200980147399.3), chemical method (invention patent 201180068282.3, invention patent 201310497967.0) and the above method...
