Abstract

Thousands of medium and low steam boilers and hot water boilers operate in the country's industry, municipal energy and agriculture. Their reliable operation is largely determined by the maintenance of a rational water-chemical regime. The main problems of source water are the presence of dissolved oxygen, iron ions, salts of calcium, and magnesium. The aim of the work is to analyze the existing technologies and equipment for water treatment for different types of boilers. Determination of physicochemical parameters and requirements for source and prepared water. Presentation of new multi-purpose energy-efficient and resource-saving water treatment equipment. The article considers the negative impact of dissolved iron, hardness salts, dissolved gases present in the feed water on the operation of boiler equipment. The main requirements for feed water in terms of hardness, the content of dissolved oxygen, and oils for steam and hot water boilers are given. The mechanism of scale formation is given. The main existing methods of feed water treatment are considered, namely softening on Na-cation exchange resin, liming, softening, and reduction of total salt content on reverse osmosis units, softening, and reduction of total salt content by the sequential passage of water through H, OH-ion exchange filters. A multi-purpose aeration-oxidation setup of rotor type (AORT) is presented, which implements the method of discrete-pulse energy input, on which it is possible to carry out operations to remove iron, manganese, hardness salts, increase pH and degassing from water.
锅炉房水处理的特点
全国工业、市政能源、农业运行的中、低蒸汽锅炉、热水锅炉数以千计。它们的可靠运行在很大程度上取决于维持合理的水化学制度。水源的主要问题是存在溶解氧、铁离子、钙盐和镁盐。本工作的目的是分析现有的技术和设备的水处理不同类型的锅炉。源水和配制水的理化参数和要求的测定。介绍一种新型多用途节能节约型水处理设备。分析了给水中存在的溶铁、硬度盐、溶气等对锅炉设备运行的负面影响。给出了蒸汽锅炉和热水锅炉对给水的硬度、溶解氧含量和含油量的主要要求。给出了水垢形成的机理。考虑了现有给水处理的主要方法,即na -阳离子交换树脂软化、反渗透装置石灰化、软化和降低总盐含量、水依次通过H、oh离子交换过滤器软化和降低总盐含量。介绍了一种多用途转子式曝气氧化装置(AORT),该装置采用离散脉冲能量输入的方法,可以进行除铁、除锰、除硬盐、提高pH值和脱气等操作。
