Embodiment approach 1

[0044] figure 1 The configuration of the water treatment device 1 according to the present embodiment is shown in . The water treatment device 1 includes an inactivation device 10 and a centrifugal solid-liquid separation device 20 . The water inlet 12a of the main body 12 of the inactivation device 10 is connected to the water intake pipe 11a from the water intake 11 of the hull. A water intake pump 11b is arranged on the water intake pipe 11a. Moreover, the piping 13 is connected to the water outlet 12b of the main body 12. As shown in FIG.

[0045] The centrifugal solid-liquid separation device 20 includes a lower liquid container 24 and a plurality of liquid cyclones 21 , 22 . In addition, a valve 25 provided below the lower liquid container 24, a storage container 26, a flushing pump 27, and a discharge pipe 28 may be included. In addition, the number of hydrocyclones is not particularly limited as long as it is two or more. Here, the case where there are two hydroc...

Embodiment approach 2

[0076] Figure 5 The configuration of the water treatment device 2 according to this embodiment is shown in . Explanations of the same symbols as in Embodiment 1 are omitted. In this embodiment, the water treatment device 2 includes a centrifugal solid-liquid separation device 20 b and an inactivation device 10 . The difference from the situation of Embodiment 1 is that: the inactivation device 10 is arranged at the rear stage of the centrifugal solid-liquid separation device 20b; 24, without storage container 26.

[0077] In the water treatment device 2 according to the present embodiment, relatively large aquatic organisms and the like in the liquid to be treated taken in from the water inlet 11 are first separated, and then the microscopic aquatic organisms and the like are exterminated by the inactivation device 10 . In this way, nothing is added to the liquid to be treated in the taken-in state in the drainage of the centrifugal solid-liquid separator 20b, so it can be...

Embodiment approach 3

[0087] Figure 6 The structure of the water treatment apparatus 3 which concerns on this embodiment is shown in . Explanations of the same symbols as in Embodiment 1 are omitted. In this embodiment, the water treatment device 3 includes a centrifugal solid-liquid separation device 20 b , an inactivation device 10 and a centrifugal solid-liquid separation device 40 . Here, the first centrifugal solid-liquid separation device 20 b is referred to as a first centrifugal solid-liquid separation device 20 b , and the subsequent centrifugal solid-liquid separation device 40 is referred to as a second centrifugal solid-liquid separation device 40 .

[0088] The first centrifugal solid-liquid separator 20b is the same as the centrifugal solid-liquid separator 20b of the second embodiment. In addition, the second centrifugal solid-liquid separator 40 is the same as the centrifugal solid-liquid separator 20 of Embodiment 1, but the reference numerals are different.

Abstract

When a plurality of cyclones are used as a separation device of a water treatment device, there have been as many lower liquid containers as the number of cyclones, resulting in high cost. Provided is a centrifugal solid-liquid separation device including: a plurality of cyclones respectively having at least a liquid inlet, a liquid outlet, and a lower liquid port; and a lower liquid container communicating with the respective lower liquid ports of the plurality of cyclones via pipes, arranged below the plurality of cyclones, and having a drain hole in its bottom side. The lower liquid container includes a space forming portion above lower opening ends of the pipes. Also provided is a water treatment device using this centrifugal solid-liquid separation device.

Description

technical field [0001] The present invention relates to a centrifugal solid-liquid separation device for separating microorganisms from liquid to be treated that is taken in by a ship from a water area of ​​a port destination as ballast water, and a water treatment device using the centrifugal solid-liquid separation device. Background technique [0002] The ship is designed to sink to the waterline when loaded with cargo and stabilize, and the propeller does not enter the water. Therefore, in a state where no cargo is loaded, the ship floats excessively due to buoyancy, and the stability of the ship and the water entry depth of the propeller cannot be ensured. Therefore, a cargo ship or the like after unloading the cargo takes in the liquid to be treated at the port and stores it in the hull, thereby bringing the waterline close to the state where the cargo is loaded. The liquid to be treated taken in at this time is called ballast water. [0003] The ballast water is car...
