Environment-friendly and efficient boiler feed water treatment system

Abstract

The invention discloses an environment-friendly and efficient boiler feed water treatment system and relates to the water treatment field. The system comprises a filter unit and a scale inhibiting and removing unit, wherein the water inlet of the scale inhibiting and removing unit is connected with the filter unit and the water outlet of the scale inhibiting and removing unit is connected with a boiler unit and can also be connected with a cooling water pond for cyclic purification of water quality; and the scale inhibiting and removing unit comprises a cover body, a barrel body, a spile, a water inlet, a water outlet, a base support, a nano antiscale metal ceramic layer, an activated delayed nano ceramic layer, a pore plate and a pore plate support, and is divided into a left chamber and a right chamber, the left chamber can be used for processing water into activated water and the right chamber is used for keeping time of the activated water. As for the activated water produced by the boiler feed water treatment system, surface tension of water can be lowered and pH value of water can be changed; and such functions as scale inhibition, scale removal, sterilization, algae removal, deoxidization, corrosion prevention, water quality purification and flue gas denitrification can be realized, circulating water and boiler pipelines can be protected, the service life of circulating water and boiler pipelines can be prolonged by several times, electric energy is not consumed, the system is truly maintenance-free, and the system is environmentally friendly.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a green and high-efficiency boiler feed water treatment system. Background technique [0002] China is an extremely water-scarce country. Statistics show that my country's population accounts for 22% of the world's total population, but its water resources are only 8% of the world's. The per capita water resources in my country are only 1 / 3 of the world's per capita water resources 4. Ranked 121st in the world, it is a water-short country recognized by the United Nations. Not only that, the distribution of water resources across the country is seriously uneven, decreasing from northeast to southwest. The area south of the Yangtze River, which accounts for 1 / 3 of the country's area, has 4 / 5 of the country's water volume, while the huge northern area has less than 1 / 5 of water. According to data from the National Bureau of Statistics, in 2011, the total discharge of industrial wast...
