Comprehensive analysis of power boiler softened water equipment

Softened water equipment is widely used in the power industry, which can effectively reduce the generation of scale on the inner wall of the boiler and prolong the service life of the boiler. The daily maintenance of softened water equipment is also very important, mainly the maintenance of operation and long-term outage.

Ensure that the input voltage and current are stable and prevent the electric control device from burning. A sealing cover should be installed outside the electronic control device to prevent moisture and water immersion. Regularly add solid granular salt to the salt box (it is strictly forbidden to add refined salt or iodized salt), and it must be ensured that the salt solution in the salt box is in a supersaturated state. When adding salt, be careful not to sprinkle solid granular salt into the salt well to prevent salt bridges from forming on the salt valve and blocking the salt suction pipeline. Since solid granular table salt contains a certain amount of impurities, a large amount of impurities will be deposited at the bottom of the salt tank and block the salt valve, so the impurities at the bottom of the salt tank should be cleaned regularly. When cleaning, open the drain valve at the bottom of the salt tank and rinse with clean water until no impurities flow out. The cleaning cycle of the salt tank should be determined according to the impurity content of solid granular salt.

Regularly check the air tightness of the ejector and the salt suction pipeline to prevent air leakage and affect the regeneration effect.
The water softener should be disassembled once a year, the impurities in the upper and lower water distributors and the quartz sand cushion should be cleaned, and the loss and exchange capacity of the resin should be checked, and the severely aged resin should be replaced.

For the deactivation and maintenance of softened water equipment, the following signs are essential:

Before the softened water equipment is out of use for a long time, the resin should be fully regenerated, and the resin should be converted into sodium type for wet maintenance. When it is out of use in summer, the water softener should be flushed at least once a month to prevent the growth of microorganisms in the exchange tank and cause the resin to mold and agglomerate. If the resin is found to be moldy, it can be sterilized. Usually soaked in 1% formaldehyde solution for several hours, and then rinsed with water until there is no formaldehyde odor. In winter, antifreeze measures should be taken to prevent the resin from cracking and breaking due to the freezing of moisture in the resin. The resin can be stored in a saline solution, and the concentration of the saline should be prepared according to the temperature conditions.

The above three are the comprehensive analysis and introduction of power boiler softening water equipment. I hope that reading can help everyone.
