At present, the company has formed a multi product system with condensate polishing system equipment for industrial water recycling, demineralized water treatment (including seawater desalination) system equipment and sewage treatment system equipment as the core, involving chemical dosing, water vapor sampling, other industrial wastewater treatment, water network control and generator transformer unit relay protection equipment. (1) Condensate polishing system equipment
In the power generation process of nuclear power and thermal power enterprises, water heated at high temperature will produce a large amount of steam for power generation. After the steam releases relevant energy and converts it into kinetic energy, it releases heat and cools down to generate a large amount of condensate. In order to ensure the steam conversion efficiency and the cleanness of the heating system in the power generation process, on the one hand, there are high requirements for the water quality used by the steam generator or boiler, so it is necessary to use the equipment of condensate polishing system for circulating treatment of water; On the other hand, through the condensate polishing system equipment, the condensate can be recycled to improve the resource utilization efficiency. However, due to certain pollution (including impurities added during chemical dosing, corrosion products in contact with metals and impurities leaked into the system) in the process of steam work and condensation into water, if the condensate is directly recycled without treatment, it will cause corrosion damage to the system or deposit in the system, reduce the system efficiency and reduce the service life of power generation equipment such as utility boilers and steam turbines. Therefore, before reusing this part of condensate, it must be deeply treated, that is, condensate polishing. According to the hygienic standard for drinking water (GB 57492006), the TDS standard for drinking water is 1000mg / L. in the production process of the power plant, the condensate polishing equipment shall meet the requirements of high pressure (pipeline pressure greater than 5MPa), high speed and large capacity. The TDS requirement for effluent is often lower than 0.15mg/l, and the water quality requirement is much higher than the standard for daily domestic water. Among them, the TDS requirements of large units of nuclear power plant for effluent tend to be close to 0mg / L. only by ultra-precision treatment of water through high-quality condensate polishing system equipment can we ensure that the water quality meets the relevant requirements and provide high-quality guarantee for the long-term stable operation of power generation equipment. Condensate polishing system equipment is a necessary water treatment system equipment for supercritical, ultra supercritical nuclear power and thermal power units. It is a permanent device of power plant.
The high tower condensate polishing system equipment provided by the company adopts the combination of filter element mechanical filtration and ion exchange of high-speed mixed bed to remove suspended impurities and cation and anion in condensate, so as to ensure that the Feedwater Quality specified by nuclear power steam generator and thermal power boiler unit can be reached. The whole system usually includes four parts: pre mechanical filtration, desalination, post filtration and supporting regeneration.

(2) Demineralized water treatment (including seawater desalination) system equipment
In industrial production and life, water is an indispensable element. However, because most of the industrial production water comes from reclaimed water, surface water, groundwater, brackish water, seawater, etc., it contains a lot of impurities, which can not fully meet the needs in some production processes, so it must be purified. According to the different requirements of water quality, the equipment of demineralized water system needs to make the steam and water quality of water vapor circulation system meet the standards of safe and economic operation through membrane process or thermal process.
1) Conventional demineralized water treatment system equipment
