Description

Technical Field

[0001] The utility model relates to the technical field of boiler water, in particular to boiler water treatment equipment. Background Art

[0002] A boiler is a heat exchange device that works by transferring the heat released when fuel is burned to water to generate steam. In this process, the quality of water is directly related to the safe operation of the boiler. Since water has the ability to dissolve and carry solids, liquids or gases, these substances may affect the purity of the water used and may pose a threat to the safe operation of pipelines and equipment. Therefore, proper treatment of boiler water to eliminate various problems and ensure the safe operation of the boiler is the main task of boiler water treatment equipment.

[0003] In addition, the application scope of boiler water treatment equipment is becoming more and more extensive. Boiler water treatment equipment plays an important role in various fields such as power plants, chemical plants, pharmaceutical and food industries. It can ensure the operating efficiency and safety of power generation equipment and improve the power generation capacity of power plants; it can protect production equipment from corrosion and scaling and extend the service life of equipment; it can ensure the quality and safety of products during the production process. At the same time, boiler water treatment equipment is also widely used in residential areas, commercial buildings, hotels and other places to provide people with clean and safe water supply.

[0004] Existing boiler water treatment equipment needs to use ion exchange columns in the process of boiler water treatment to soften the water. The hardness of water is mainly composed of cations therein: calcium (Ca2) and magnesium (Mg2) ions. When the raw water containing hardness ions passes through the ion exchange column, the calcium and magnesium ions in the water are replaced with the sodium ions in the ion exchange column. The exchange column adsorbs the calcium and magnesium ions and the sodium ions enter the water. In this way, the water flowing out of the exchange column is softened water with the hardness ions removed. However, due to the limited sodium ions inside the ion exchange column, during the process of treating boiler water, when the sodium ions inside the ion exchange column are insufficient, the water cannot be softened. The ion exchange column needs to be regenerated with sodium chloride solution before the water can be softened again. The regeneration process of the ion exchange column wastes a lot of time.
