Description
The present invention relates to a system for improving the turbidity of a ship water tank, and more particularly, to a turbine system for improving the turbidity of a power plant by using a multistage device to filter fine particles including mud contained in seawater discharged as a coolant in a power plant using seawater as a coolant And to a system for making use of pear hot water as a water temperature regulating water for a farm or a heat pump or water for cogeneration.
Generally, thermal power or nuclear power plants use seawater as cooling water.
At this time, the seawater used as the cooling water is taken from the deep sea because the temperature is low, and the collected seawater is used as a coolant for condensing the steam discharged from the end of the steam turbine in the cycle apparatus of the power plant.
On the other hand, gypsum, which is the seawater discharged after being used as cooling water in the power plant, is discharged at a high temperature, so it is often used for control of water temperature in the winter season in the surrounding farms. In addition, since the temperature of the hot water is high, in order to use the heat energy contained in the hot water, various heat pumps and hot water discharged from the power generation water are used in the cogeneration facilities.
However, since the sewage water discharged from the power plant is seawater collected from the deep sea water, a lot of clay components may be introduced depending on the condition of seawater, causing problems in various facilities using the sewage water, increasing the heat resistance, When the hot water is used, there is a problem that the turbidity of the fish farm is increased, which adversely affects fish farming.
In order to solve these problems, conventionally developed sewage water filtration apparatuses are classified into gravity filtration type and rapid filtration type.
The gravity filtration type is advantageous in reducing the quality of the filtrate and reducing the operation cost, but has a disadvantage in that the area occupied by the filtration device is too large. The rapid filtration type is advantageous in producing a large amount of filtrate in a short time, There is a drawback in that the maintenance effort of maintenance is relatively large.
On the other hand, in the conventional gravity filtration type or rapid filtration type, when the seawater containing a large amount of clay is filtered, the backwashing process must be performed frequently, so that the filtration efficiency is remarkably decreased and the problem that the filtration filter is damaged quickly due to backwash there was.
Therefore, it is required to have a flushing water filtration system in which the flushing water discharged from the power generation water can be filtered at a high efficiency while the filtration can be thoroughly performed, and the utilization of flushing water can be increased.
Patent Registration No. 10-1516726 (Registration date: May 24, 2015)
SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a filtration system capable of selecting a filtration step necessary for the amount of mud contained in the waste water of a power plant by multi-stage filtration, Water turbidity improving system capable of improving the turbidity of the flushing water with high efficiency.
In order to achieve the above object, the present invention provides a system for improving the turbidity of a water tank of a power plant, comprising a water collecting tank (101) into which seawater is discharged after being used as cooling water in a power plant, a strainer And a
A
The
The present invention has the following effects.
First, the degree of improvement of the turbidity of the hot water is remarkably high by performing the three filtration steps, and the intermediate filtration step can be omitted by a simple operation depending on the state of the hot water, so that the filtration of the hot water can be performed quickly and efficiently.
Second, by applying the wedge wire type screen drum to the final filtration tank, the conventional PE Disc Plate filter is less durable due to the impact caused by the impact for a long period of use, and the problem of periodic nozzle filter inspection is solved.
Third, when the turbidity is high due to the high amount of mud contained in the hot water, the mud can be quickly removed by using the dust collecting tank and the venturi pipe, thereby supplying the intermediate filtered water to the final filtration tank.
Fourth, since the hot water is heavier than ordinary water, the height of the siphon tube is adjusted to be close to the height of the filtrate water discharge pipe, so that the reverse process is smoothly performed.
