1548125955(1)Calculation of the total softened water volume of the boiler house There are three methods for softening the boiler water: the chemical treatment method, the ion exchange softening treatment method, the magnetic field softening treatment method and other softening treatment methods. In the present design, an ion exchange softening treatment method which is widely used at present is used, in which an ion exchange agent selects an organic ion synthesis resin, and a softening method uses a fluidized bed ion exchange method. The fluid bed ion exchange softening unit can operate continuously. According to the operation mode, it can be divided into two types: gravity type and pressure type; according to the operation system, it can be divided into three types: single tower type, double tower type and three tower type. According to the raw water quality index, this design is intended to soften the feed water by countercurrent regenerative sodium ion exchange method without a top pressure fixed bed. The advantages of the fluidized bed are high quality of the effluent, continuous operation, convenient operation, and less exchange dose required. The principle of countercurrent regenerative sodium ion exchanger without top pressure fixed bed is as follows: sodium ion exchanger is equipped with a certain height of sodium ion exchange resin as an exchange agent. The raw water passes through the exchanger layer from top to bottom, and the sodium ions on the exchanger displace the calcium and magnesium ions in the raw water to soften the water.
