Description

Technical Field

[0001] This invention relates to the field of water filtration equipment technology, specifically to an open-type water circulation filtration device for steam turbines. Background Technology

[0002] In modern industry, especially in the power, chemical, and metallurgical sectors, steam turbine cooling systems typically employ open-loop water circulation systems. These systems utilize external water sources (such as rivers, lakes, or oceans) for cooling. The water absorbs heat generated by the steam turbine through the system's heat exchangers and is then recycled. This cooling method is relatively simple and low-cost, but it also presents some inherent problems, particularly in water quality management.

[0003] Chinese Patent Publication No. CN 221535837 U discloses an open-type water circulation filtration device for steam turbines, comprising a housing with a circulating water inlet, a circulating water outlet, a mid-level drain valve, a low-level drain valve, and a flushing water inlet. The housing contains a conical filter screen and a control structure for controlling the rotation of the conical filter screen. The included angle of the conical filter screen's cross-section is not less than 90°, and the water flow direction of the flushing water inlet is perpendicular to the filter wall of the conical filter screen. The purpose of this invention is to solve the technical problems existing in the prior art and provide an open-type water circulation filtration device for steam turbines that can prevent debris from being blown from one side of the conical filter screen to the other during backwashing.

[0004] However, the above solution still has the following problems:

[0005] Low filtration efficiency and insufficient precision: The common use of a single fixed filter screen or grid can only intercept larger suspended particles, and the removal effect on fine mud, sand, microbial slime and other particles is very poor.

[0006] Unable to add chemicals online, resulting in weak ability to prevent biological contamination: Traditional systems require shutdown to add bactericides, scale inhibitors, etc. to the water, making continuous prevention impossible;

[0007] The equipment has limited functionality and low integration: functions such as filtration, dosing, circulation, and sewage discharge are usually performed by separate equipment, which occupies a large area, has complex system pipelines, poor operational coordination, low degree of automation, and makes it difficult to achieve refined management.

[0008] Therefore, the present invention requires the design of an open-type water circulation filtration device for steam turbines to solve the above-mentioned problems. Summary of the Invention

[0057] Compared with the prior art, the open-loop water circulation filtration device for steam turbines provided by the present invention has the following significant advantages:

[0058] This invention innovatively employs a three-stage filtration process:

[0059] Primary filtration: In the water filter box 21, preliminary coarse filtration is carried out through multiple layers of filter plates 36 to intercept most of the larger suspended solids. The material of the filter plates 36 can be replaced as needed, and multiple filter plates 36 of different materials can also be used. The materials of the filter plates 36 include quartz sand, activated carbon, and polypropylene.

[0060] Secondary filtration: Water flows through the top water supply pipe 31 into the filter cartridge 3 for deep fine filtration to further remove fine particles. An annular filter screen can be installed inside the filter cartridge 3. The annular filter screen is made of RO membrane.

[0061] Three-stage filtration and treatment: Water enters the conveying chamber 42 and the dosing and mixing chamber 41, where it is dispersed by the mechanical action of the screening conveying rod 45 and two screening baffles, and is fully mixed with the reagent to achieve final filtration and chemical treatment. This design makes the water purification very thorough, effectively prevents scale and blockage of the heat exchanger, and maintains the heat exchange efficiency at the best level.
