Description

Technical Field

[0001] This utility model belongs to the field of generator set circulating water optimization technology, specifically a generator set circulating water optimization system. Background Technology

[0002] The generator set circulating water system is a key system in a power plant and an indispensable cooling system for maintaining the normal operation of the power plant. Cooling towers are often used to cool the generator set. The principle of a cooling tower is to introduce cold water into the cooling tower and circulate it continuously to cool the unit. When the water inside the cooling tower gets hot, it produces water vapor, which is discharged to the outside through the top.

[0003] The circulating water used in existing generator sets is directly sourced from rivers, lakes, or groundwater, after removing silt and other impurities. However, the water optimization is not thorough enough, and it is easy for structural elements to form in the circulating water system, which can affect the efficient operation of the circulating water system and even the stable operation of the generator set. Therefore, a generator set circulating water optimization system is proposed here. Utility Model Content

A third connecting pipe is provided at the end of the booster pump away from the second connecting pipe. A reverse osmosis membrane filter group is provided at the end of the third connecting pipe away from the booster pump. The reverse osmosis membrane filter group has three reverse osmosis membranes. The three reverse osmosis membranes are connected in series by pipes. The tail end of each reverse osmosis membrane is connected to a concentrate pipe through a flange. The tail end of the concentrate pipe away from the reverse osmosis membrane is connected to a drain pipe through a flange. The tail end of the last reverse osmosis membrane in the reverse osmosis membrane filter group is connected to an outlet pipe through a flange.

[0006] Preferably, the sloping bottom has two inclined surfaces. The first inclined surface has a gentler slope and is used to support the first filter screen and the second filter screen. Both the first filter screen and the second filter screen are inserted into the inner wall of the filter pool. The mesh diameter of the first filter screen is larger than that of the second filter screen. The circulating water raw water of the generator set is directly pumped by the water pump into the filter pool on the side of the first filter screen away from the second filter screen. The raw water can come from rivers, lakes or groundwater near the generator set. These water sources usually contain pollutants such as suspended solids, organic matter and microorganisms. The first filter screen and the second filter screen can perform dual filtration on these raw waters to remove silt, suspended solids, some organic matter and microorganisms from the water. The sloping bottom structure design facilitates the flow of water in the filter pool on the side of the first connecting pipe.

The end of the first connecting pipe away from the filter tank is connected to the water inlet of the ultraviolet water purifier through a flange. When cleaning and maintaining the filter tank, the valve on the first connecting pipe can be closed and the valve on the drain pipe can be opened. After removing the first filter screen and the second filter screen, the filter tank can be rinsed with water to allow the sediment in the filter tank to be discharged through the drain pipe.

[0009] Preferably, the second connecting pipe is connected to the outlet of the ultraviolet water purifier via a flange, and the end of the second connecting pipe away from the ultraviolet water purifier is connected to the inlet of the booster pump via a flange. The ultraviolet water purifier is a publicly available technology that can sterilize and disinfect the water flowing through the reaction chamber of the ultraviolet water purifier by generating short-wave ultraviolet light with a central radiation wavelength of 253.7nm through the built-in ultraviolet lamp, effectively killing organic matter and microorganisms in the water.

[0010] Preferably, the third connecting pipe is connected to the outlet of the booster pump via a flange, and the end of the third connecting pipe away from the booster pump is connected to the reverse osmosis membrane filter group via a flange.
