Production process for demineralized water equipment in thermal power plant boilers

Thread Content

　　A boiler is a heat exchange device used to produce steam or hot water. With economic development, boilers are being used more and more widely in various sectors of production and daily life. Water serves as the heat exchange medium in boilers, and the quality of the water supplied to the boiler has a crucial impact on its safe operation, energy consumption, and service life. There are a wide variety of boilers, which can be classified into different categories based on their structural design, pressure, evaporation capacity, combustion method, and type of fuel used. Due to differences in capacity, water volume, evaporation rate, and operating pressure, various types of boilers have different requirements regarding the quality of feedwater and boiler water. Generally, the larger the capacity, the smaller the water capacity; the greater the evaporation rate, and the higher the operating pressure. Boilers with such conditions have higher requirements regarding water quality. 　　Production process for demineralized water equipment in thermal power plant boilers 1. Ion exchange is used, and the process is as follows: Raw water → Raw water pressure pump → Multi-media filter → Activated carbon filter → Water softener → Precision filter → Cation resin filter bed → Anion resin filter bed → Mixed cation-anion resin bed → Microporous filter → Water usage point. 【Laitlead Hefei Water Treatment Equipment Company www.hefeishui.com】 2. The process uses reverse osmosis combined with mixed-bed filtration, and it is as follows: municipal water supply network → raw water pump → flocculation chemical addition → mechanical filter → activated carbon filter → scale inhibition chemical addition → safety filter → high-pressure pump → reverse osmosis unit → intermediate water tank → mixed-bed pump → mixed-bed unit → precision filter → desalinated water tank. 　　3. The EDI method is used, and the process is as follows: Raw water → Raw water pressure pump → Multi-media filter → Activated carbon filter → Water softener → Precision filter → First-stage reverse osmosis unit → Intermediate water tank → Intermediate water pump → EDI system → Microporous filter → Point of use. 　　Features of desalination water equipment for thermal power plant boilers: high desalination efficiency, low operating pressure thanks to imported low-roll composite reverse osmosis membranes, excellent quality of the produced water, low operating costs, long service life, high efficiency, and low noise level. 　　Online conductivity meters and pH meters for raw water and treated water allow for continuous monitoring of water quality. 　　Imported online product water flow meter for concentrated water, allowing for real-time monitoring of the amount of product water and the system’s recovery rate. 　　A automatic cyclic cleaning system is configured for cleaning in case the membrane becomes contaminated. The quick flush valve periodically washes the membrane surface, reducing the rate of membrane fouling and extending its service life. 　　I hope we can learn from each other, discuss together, and make progress as a group.
