Description

Technical Field

[0001] This utility model relates to the field of steam water collection and pumping equipment for gas turbine boilers, specifically to a pumping water cooling device and a boiler cooling pool pumping water saving system. Background Technology

[0002] Gas turbines are the most high-end products in the energy and power equipment field, representing the highest technological level of the equipment manufacturing industry. As the name suggests, aero-engine-derived gas turbines are gas turbines modified from aero engines. Aero-engine gas turbines exhibit diversified and serialized development characteristics. In terms of diversification, different types and levels of gas turbines can be developed based on the same aircraft. Gas turbines and aero engines share a wide range of technological commonalities, and can share and utilize design systems, manufacturing systems, talent systems, and testing systems. Therefore, based on the huge market demand and obvious application advantages of gas turbines, developing gas turbines by relying on high-performance, mature aero engines and advanced industrial technologies and design methods has become an industry consensus. There are two ways to transfer aero engine technology to gas turbines: one is to directly modify and derive mature aero engines to form aero-engine-derived gas turbines; the other is to transplant aero engine technology to heavy-duty gas turbines, researching and developing a new generation of heavy-duty gas turbines.

[0003] One crucial component of aero-derivative gas turbines is the boiler. To better utilize resources, boiler steam is recovered. The collected steam-water flows by gravity through pipelines to a boiler cooling pool, where it is cooled before being pumped back to the forebay for reuse. However, this process currently faces several challenges, including at least the following:

[0004] 1. During the steam collection process from the boiler, the steam temperature reaches as high as 200 degrees Celsius immediately upon recovery. Even after the steam-water flows into the boiler cooling pool, its temperature remains high at 80-90 degrees Celsius. The water pump continuously pumps this high-temperature water, causing components such as seals to age prematurely due to prolonged exposure to high temperatures. This leads to deformation, seal failure, and leaks. Mechanical seals are prone to failure at high temperatures, and the lubricating grease also decomposes more rapidly, resulting in accelerated bearing wear. Therefore, high-temperature resistant water pumps are currently used, but the improvement in these issues is not significant.

[0005] 2. Currently, water pumps in these boiler cooling tanks are added for cooling. To avoid scale buildup in the pumps, demineralized water is used for cooling. However, the boiler cooling tank does not always have a large amount of water, so the pumps are sometimes shut down. At this time, there is no need to continue supplying demineralized water, but the demineralized water is always supplied. Demineralized water is very expensive, and the opening and closing of the demineralized water cannot be synchronized with the pumps, which results in waste of demineralized water.

[0006] 3. Currently, the operation of using demineralized water to cool the boiler cooling pool has achieved a certain cooling effect, but there is still room for improvement in this cooling effect. Utility Model Content
