Description

Technical Field

[0001] This utility model relates to the field of steam-water separation technology, and in particular to a high-efficiency steam-water separation device for gas turbine intake. Background Technology

[0002] Gas turbines are core power equipment in energy, electricity, and other industrial sectors. During operation, gas turbines require a large amount of air to be drawn in as the combustion medium. However, in high humidity or rainy / foggy weather conditions, the intake air often carries a large amount of water mist or droplets. This moisture, after entering the compressor, can easily cause blade erosion, fouling, and a decrease in aerodynamic performance. In severe cases, it can even cause compressor surge or unit vibration, affecting the safe and stable operation of the gas turbine. Therefore, the gas turbine intake system must be equipped with a pre-gas-water separator to remove water droplets, water mist, and some solid impurities from the air, protecting the downstream precision filters and compressor blades.

[0003] Currently, the steam-water separators widely used in gas turbine intake systems are mostly fixed honeycomb structures, and their core separation units are usually integral or bonded structures. These structures have obvious drawbacks in use: First, when the separator experiences material aging, cracking, or blockage of the air inlet due to operation, it will lead to increased air intake resistance and increased unit energy consumption. Second, partial damage requires replacement of the entire separation unit, resulting in high maintenance costs. Third, the separation effect of a damaged separator will drop sharply, causing rain and mist to directly penetrate and spray onto the downstream fine filter, causing severe blockage of the fine filter in a short period of time. This not only threatens the safe and stable operation of the unit but also significantly shortens the service life of the expensive fine filter.

[0004] Therefore, we propose a high-efficiency steam-water separator for gas turbine inlet to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a high-efficiency steam-water separation device for gas turbine intake.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency steam-water separation device for gas turbine intake, comprising an upper main plate, a lower main plate, and hexagonal ring blocks. Air ducts are evenly distributed on the six faces of the hexagonal ring blocks. Each hexagonal ring block is connected to the others via interlocking blocks to form a honeycomb steam-water separation unit. The upper main plate is positioned above the honeycomb steam-water separation unit, and the lower main plate is positioned below the honeycomb steam-water separation unit. The upper and lower main plates are connected to each other via side plates. The upper main body plate is provided with a cleaning port, and a cap is threadedly installed at the opening of the cleaning port. The position of the cleaning port corresponds one-to-one with the position of the hexagonal ring block. The lower main body plate is provided with a converging groove and a collecting cavity. The bottom opening of the converging groove is connected to the top opening of the collecting cavity, and the position of each converging groove corresponds one-to-one with the position of the hexagonal ring block.

[0007] Preferably, each of the six sides of the hexagonal ring block is provided with a plug-in groove that is compatible with the plug-in block. The plug-in block is inserted into the plug-in groove of two adjacent hexagonal ring blocks to complete the splicing action of adjacent hexagonal ring blocks.

[0008] Preferably, the bottom surface of the inner wall of the converging groove and the collecting cavity is designed as an arc surface, and the lowest point of the arc surface points to the bottom opening of the converging groove and the collecting cavity.

[0009] Preferably, sealing gaskets are provided at the contact surfaces of the upper main plate, lower main plate, and side plate with the honeycomb steam-water separation unit.

[0010] Preferably, mounting holes are symmetrically provided at both ends of the side plate.

[0011] Preferably, the inner wall of the hexagonal ring block and the air duct opening is provided with a hydrophobic coating, which is a polytetrafluoroethylene coating.

[0012] Preferably, a drain valve is connected to the bottom opening of the collection cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The core honeycomb vapor-water separation unit of this utility model is composed of multiple independent hexagonal ring blocks spliced ​​together by plug-in blocks. This design allows any hexagonal ring block to be replaced individually when it ages, breaks or becomes clogged, without having to scrap the entire separation unit. The upper main plate is equipped with cleaning ports that correspond one-to-one with each hexagonal ring block. Maintenance personnel only need to unscrew the cover to insert the high-pressure water gun or cleaning tool directly into the corresponding air duct for precise spraying and cleaning. This achieves online cleaning without disassembly, making maintenance very convenient and efficient. It can effectively restore the steam-water separation performance and prevent the air inlet from becoming blocked. The polytetrafluoroethylene hydrophobic coating on the hexagonal ring block and the inner wall of the air duct can greatly reduce the adhesion of water droplets on the wall surface, promote the faster collection and discharge of separated water, and reduce airflow resistance. The lower main plate features a unique collecting groove and a collection cavity design, with the bottom surface of the inner wall being an arc surface that guides water flow. It is connected to the drain valve to form a highly efficient drainage system. This system can quickly collect the liquid separated from each hexagonal ring block and completely discharge it from the device, effectively preventing the risk of accumulated water being re-swept away by the airflow and ensuring a stable separation effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] like Figures 1-5 As shown, this utility model proposes a high-efficiency steam-water separator for gas turbine intake, comprising an upper main plate 1, a lower main plate 2, and hexagonal ring blocks 4. The upper main plate 1 serves as the top supporting structure of the device. Its core feature is that each of the lower hexagonal ring blocks 4 is equipped with a cleaning port 101. The outer end of the cleaning port 101 is fitted with a completely sealable cover 102 through a threaded connection. This design allows operation and maintenance personnel to perform maintenance without disassembling the entire device. They only need to unscrew the cover 102 one by one to clean the corresponding individual hexagonal ring blocks 4 with a high-pressure water gun through the channel.

[0019] The core functional unit of the device is a honeycomb-shaped gas-water separation module composed of multiple hexagonal ring blocks 4 spliced ​​together by a plug-in structure. Each hexagonal ring block 4 has air ducts 401 on its six sides for gas to pass through and be separated by inertia. To achieve rapid and precise modular assembly, standard plug-in slots 402 are machined on the six outer surfaces of each hexagonal ring block 4. The plug-in block 5 acts as a connecting key and is precisely embedded in the plug-in slots 402 of two adjacent hexagonal ring blocks 4, thereby achieving a tight and firm splicing of all hexagonal ring blocks 4 on the horizontal plane. This design ensures that any hexagonal ring block 4 can be individually located and replaced when it ages, cracks or becomes blocked due to long-term use.

[0020] Example 1 Figures 1-5 As shown, the present invention proposes a high-efficiency steam-water separation device for gas turbine intake. Compared with Embodiment 1, this embodiment further includes: the bottom of the device is the key part responsible for collecting and discharging the separated liquid. The upper surface of the lower main body plate 2 is designed with an independent collection groove 201 directly below each hexagonal ring block 4. The bottom outlet of all collection grooves 201 is connected to a common collection cavity 202 that runs through the entire bottom of the device. In particular, the bottom surface of the inner wall of the collection grooves 201 and the collection cavity 202 are designed with a smooth arc surface to ensure that the liquid flows to the lowest point outlet under the action of gravity. The bottom opening of the collection cavity 202 is finally connected to a drain valve 203, and the separated water is continuously and thoroughly discharged from the device.

[0021] To ensure the sealing performance of the device in the environment, elastic sealing gaskets are installed at all contact interfaces between the upper main plate 1, the lower main plate 2, the side plate 3 and the internal honeycomb steam-water separation module. The side plates 3 on both sides are bolted to the frame of the external gas turbine intake system through mounting holes symmetrically opened at both ends, thereby firmly integrating the entire steam-water separation device into the intake pipe.

[0022] The working process of this utility model is as follows: Moist air containing water droplets and impurities enters the air duct openings 401 of each hexagonal ring block 4 from the front end of the device under the suction of the gas turbine. When passing through these narrow and tortuous channels, the air changes direction according to the streamline, while the larger water droplets and particles cannot follow the airflow path due to inertia and continue to hit the inner wall of the air duct coated with a hydrophobic polytetrafluoroethylene coating. The captured water droplets quickly condense under the action of the hydrophobic coating and drip downwards under the action of gravity. They first fall into the corresponding collecting groove 201, then flow into the common collecting chamber 202, and finally exit the device through the drain valve 203. The dry and clean air that has been separated flows out from the rear end of the device and enters the next stage of the fine filtration system, thereby achieving effective protection for the fine filter and the gas turbine compressor.

[0023] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
