Problems solved by technology

In this way, in order to ensure the effect of ballast water treatment, the power of the ultraviolet unit is generally adjusted to the maximum. Since the power consumption of the ultraviolet unit is very large, this operation method not only brings great pressure to the ship's power system, but also causes a lot of energy wasted

Embodiment

[0069] image 3 with figure 2 They are the front view and the top view of the structure of the ultraviolet inactivation device of the embodiment of the present invention. The ultraviolet inactivation device of the ballast water treatment device with adjustable power in this example includes 101 flowmeter, 102 ultrasonic generator, and 103 ultraviolet generator , 104 light intensity sensor and 105 radiator. There are a total of 5 ultraviolet generators in the cavity with a radius of d 0 The length, width and height of the cuboid cavity are 28cm, 20cm, and 20cm respectively.

[0070] In the present invention, the shape of the reactor is a rectangular parallelepiped, and the effective volume of the cavity is:

[0071] V=abc-naπr 2

[0072] Where a, b, and c are the length, width and height of the cuboid cavity, r is the radius of the ultraviolet generator, and n is the number of ultraviolet generators in the cavity.

[0073] According to Lambert's law, the intensity of ultraviolet radi...

Abstract

The invention relates to a ballast water treatment system ultraviolet inactivation device with adjustable power and a control method thereof. The device comprises a reactor, flowmeters used for detecting the flow at a water inlet and a water outlet, ultraviolet generators uniformly distributed in a cavity of the reactor, a rotary switch used for adjusting the power of the ultraviolet generators, and a controller connected with the flowmeters and the rotary switch respectively, and the controller receives a flow signal of the flow meter, adjusts the rotating angle of the rotary switch accordingto the flow signal, and adjusts the light intensity of the ultraviolet generator. Compared with the prior art, the method has the advantages that the system power is adjusted according to the systemflow, the load pressure of the system is reduced, and energy waste is avoided.

Description

Technical field [0001] The invention relates to the technical field of ship ballast water treatment, in particular to an ultraviolet inactivation device for ballast water treatment system with adjustable power. Background technique [0002] Ship's ballast water refers to an appropriate amount of outboard water injected into the ballast tank to enhance the ship's ability to resist wind and waves and stability. Ballast water is the guarantee that the ship can sail stably, but it also carries a lot of marine life. The untreated injection and discharge of ballast water can cause serious ecological, economic and health problems. [0003] Based on the above reasons, the International Maritime Organization (IMO) adopted the International Convention on the Control and Management of Ballast Water and Sediments on Ships, which stipulates that the discharge of ballast water requires the killing and removal of microorganisms in the ballast water. A variety of ship ballast water treatment dev...
