Fulai 9500 single valve double tank fully automatic water softener 4-8T/H water softening equipment, with a single valve simultaneously controlling two resin tanks (one in use and one backup, alternating regeneration), can continuously supply softened water. Due to the use of softened water regeneration, the regeneration effect is good and suitable for various water use situations. For systems with large water consumption, multiple units can be operated in parallel.
Working Principle:The hardness of water is mainly composed of cations such as calcium (Ca2+) and magnesium (Mg2+) ions. When raw water containing hardness ions passes through the resin layer inside the exchanger, calcium and magnesium ions in the water are adsorbed by the resin, while sodium ions are exchanged and released. The water flowing out of the exchanger in this way is softened water with removed hardness ions. When the resin adsorbing calcium and magnesium ions reaches a certain level, the hardness of the effluent increases. At this time, the water softener automatically regenerates the failed resin, using a higher concentration of sodium chloride solution to pass through the failed resin and restore it to sodium type resin. The system is an integrated device consisting of resin tanks, salt tanks, and controllers. Installed centralized control valve from FLECK company in the United States to achieve program control operation and automatic regeneration; Adopting the siphon principle for salt absorption, automatic water injection for salt hydration and concentration ratio, without the need for auxiliary equipment such as salt pumps and salt dissolution. There are several ways to start regeneration:Time type, real-time traffic type, and delayed traffic type. Industrial boiler water softeners generally use flow instant type, but the total exchange capacity of the softener should meet the water demand requirement for processing for at least 6 hours. In fact, it is generally required that the total exchange capacity of the softener should meet the water demand requirement for processing for 8-12 hours. For small boilers with a water consumption of less than 2t/h, from the perspective of equipment purchase cost, sometimes time type boilers are also selected. General requirements for installation:
1. The inlet pressure should be between 0.2-0.5MPa. When the water source pressure cannot meet the requirements, a booster pump can be installed to increase the inlet pressure. If the pressure is too high, a pressure reducing valve should be installed to control the inlet pressure.
2. The inlet water temperature should be between 5-45 ℃, and the power supply should be AC 200V/50Hz.
3. The water softener should be installed on a sturdy platform with unobstructed drainage nearby and sufficient space for operation and maintenance.
4. The working environment temperature should be between 5-50 ℃, and the relative humidity should be ≤ 95% (at 5 ℃).
