Scheme description

There are many water systems in power plants, mainly including boiler water treatment, circulating cooling water treatment, condensation water treatment and wastewater treatment. As an important working medium in the whole thermal system, water quality plays a vital role in the normal operation of the whole system.


In the reverse osmosis system of boiler water treatment, the raw water contains a lot of impurities and suspended solids because of the poor water quality. These impurities and suspended solids will increase the pressure difference of the system, reduce the water yield, reduce the desalination rate and make back-washing difficult. Therefore, in order to improve the performance of RO membranes and prolong the service life of RO membranes, the reverse osmosis system needs to be pre-filtered to remove the larger size of impurities and colloids in raw water. The setup of self-cleaning filter can solve this problem. The self-cleaning filter has the characteristics of high filtering precision, large filtering area and high automation. Its filtering precision can reach up to 25 microns. It can remove the solid impurities which affect the life of reverse osmosis membrane. At the same time, it does not affect the operation of water system when self-cleaning filter screen. Its use will greatly improve the service life of reverse osmosis membranes, reduce the operating costs of the system, and ensure the continuity and stability of the water supply system.


The use of self-cleaning filters can effectively reduce the turbidity of the water system, improve the heat exchange system (cooling system), protect the nozzle from blocking (fire fighting system), and reduce the turbidity of the water system in the cooling water pipeline system of the circulating pump motor, the lubricating water pipeline system of the circulating pump bearing, the automatic sprinkler water supply pipeline system and the public water pipeline system of the power plant. Less water supplement and lower energy consumption to ensure continuity and stability of water supply system.
Our self-cleaning filter equipment has been used in many power plants in China, and has achieved very good economic benefits as well as very good social benefits.
