Ship ballast water filter performance test device

Abstract

The present invention relates to a ship ballast water filter performance experiment device. The device comprises a circulating water system unit, a heterogeneous product access unit, and a distributed intelligent measurement and control system. The heterogeneous product access unit is configured to improve the mode of the filter access experiment device, take fresh water, sea water or other industrial water as fluid medium, and take plankton, suspended particles and organic carbon granules to simulate the inner impurities of the engineering environment to perform performance test of an automatic reverse cleaning filter access device for engineering of the ship ballast water, the sea drilling platform, the sea water desalination, the nuclear power plant water treatment and wastewater treatment, and the aqueous medium circulation mode accords with the real industry flow mode, so that the test result can reflect the scene real application state to a certain extent. Through building of the invention, the ship ballast water filter performance experiment device can realize the performance test of the automatic reverse cleaning filter access device at home and abroad to lay the foundation for researching a filter with big flow, low loss of pressure and high reliability and pushing the automatic reverse cleaning filter localization.

Description

technical field [0001] The invention relates to the technical field of water medium filtration and separation, in particular to a performance experiment device for a ship's ballast water filter. Background technique [0002] At present, the traditional filter and sand filter equipment in the municipal water supply, steel, petrochemical, metallurgy, power plant and other industrial cooling circulating water, sewage treatment and other large-flow filtration water occasions have prominent problems, such as easy clogging, inconvenient cleaning operation, and small flow. The hardware configuration cost increases when forming a large-scale filter station, and the overall effect of the treatment of some special water quality with high salinity, high turbidity, and large particles is not good. In terms of international marine ships, in order to effectively prevent the invasion of alien species caused by the ballast water of ships, the International Maritime Organization (IMO) passed...

AI Technical Summary

Problems solved by technology

However, the safety and reliability of the filtration system has a very important impact on the industrial circulating water system, ship navigation, etc., and its performance test is imperative. On the one hand, frequent adjustments aggravate the mechanical wear of the valve, increase the workload of equipment maintenance and equipment investment; on the other hand, the control accuracy is poor and a large amount of electric energy is wasted

In addition, the water hammer effect caused by the direct power frequency starting and braking of the pump motor also has a destructive impact on the pipe network, valves, etc.

This method has low efficiency in complex operation, lack of accurate, safe and efficient data acquisition and analysis management system support, and insufficient anti-corrosion protection results in low reuse rate; based on fluid simulation calculation analysis, mathematical modeling is complex and the calculation cycle is long, ideal conditions and actual work There are still many differences in the product data measured in the large environment of the environment; although the self-cleaning filter products have the same principle, they have various specifications and types, which brings a lot of pipeline modification work to the connection, which makes the test experiment inconvenient, water and electricity, etc. High energy consumption and low economic benefits
