Abstract

(57) [Summary] [Purpose] Without causing pollution problems or problems such as clogging,
Floating organisms such as plankton are removed from the taken natural water. [Structure] Floating organisms such as plankton existing in natural water taken from the sea, lakes, rivers, etc., are preyed and removed by the filtered feeding organisms of the bioscreen 2 provided in the water channel 7, and then the equipment and piping of the plant 5 Supply to 3, 4, and 6.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plant water intake device that supplies natural water taken from the sea, lakes, rivers, etc. to equipment and piping.

[0002]

[Prior Art]

 Conventionally, in plants that supply natural water taken from the sea, lakes, rivers, etc. to equipment and pipes, it is possible to prevent floating organisms such as plankton existing in the taken natural water from adhering to equipment and pipes and polluting them. To do this, chemicals such as chlorine were poured into the natural water that was taken in, and organisms were physically removed by microscreens.

[0003]

[Problems to be solved by the device]

 In the above-mentioned plant, chemicals such as chlorine were injected into the natural water taken in, or organisms were physically removed by a microscreen, but in the former case, it cannot be used due to environmental problems such as pollution. In the latter case, there was a problem that it could not be used due to clogging.

The present invention has been proposed in view of the above problems, and an object thereof is to remove floating organisms such as plankton from natural water taken in without causing problems such as pollution problems and clogging. The point is to provide a water intake device for a plant that can.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention filters floating organisms such as plankton existing in the taken natural water in a plant that supplies natural water taken from the sea, lake, river, etc. to equipment and pipes. A bioscreen for feeding by feeding organisms is installed in the waterway.

[0006]

The water intake device of the plant of the present invention is configured as described above, and the bioscreen provided in the water intake channel collects floating organisms such as plankton existing in natural water taken from the sea, lake, river, etc. After predation and removal by feeding organisms, it is supplied to the equipment and piping of the plant.

[0007]

【Example】

 Next, the plant water intake device of the present invention will be described with reference to an embodiment shown in FIG. 1. 1 is natural water such as sea, lake and river, 5 is plant, 4 is water intake pipe of plant 5, 3 is water intake pipe. 4 is an intake pump, 7 is an intake channel, 6 is a water discharge pipe of a plant 5, 8 is a discharge channel, 2 is a bioscreen which is the most characteristic feature of the present invention. There is.

Next, the operation of the water intake device of the plant shown in FIG. 1 will be specifically described. If seawater is passed through one long pipe, the number of fouling organisms (filtering feeding organisms) that adhere to the inner surface of the pipe and pollute the pipe are large and large near the inlet, and the bait at the outlet Since the plankton, which becomes a sickness, is eaten upstream and the number is small, the growth is poor and the number is small.

The bioscreen 1 applies this principle to prey on and remove floating organisms such as plankton in natural water supplied to equipment and pipes of a plant by a filter feeding organism. In addition, since the organisms that are born and released from the filtered feeding organisms of the bioscreen 1 require several tens of days to several weeks to grow until they have the attachment ability, they may attach to downstream equipment and pipes. Absent.

[0010]

[Effect of the device]

 The water intake device of the plant of the present invention, as described above, after precipitating and removing floating organisms such as plankton existing in natural water taken from the sea, lake, river, etc. by the filter feeding feeding organism of the bioscreen provided in the water channel Since it is supplied to plant equipment and piping, it is effective in removing floating organisms such as plankton from natural water that has been taken in without causing pollution problems or problems such as clogging.
