What is the working process of the automatic boiler water softening equipment now? Author: boiler water softening equipment automatic regeneration may be initiated according to time or flow, boiler water softening processes and automatic device, generally consists of the following cycle of steps consisting:. A sodium ion exchange operation (working) the raw water Under certain pressure (0.2-0.6Mpa) and flow rate, through the valve cavity of the controller, enter the container (resin tank) containing ion exchange resin, the Na+ contained in the resin and the cations in the water (Ca2+, Mg2+, Fe2+... Etc.) Exchange to make the content of Ca2+ and Mg2+ ions in the effluent of the container meet the established requirements, realizing the softening of hard water. B. After the sodium ion exchanger backwashing resin fails, before regeneration, backwash it with water from the bottom up. There are two purposes of backwashing. One is to loosen the compressed resin layer during operation by backwashing, which is conducive to the full contact of resin particles with the regenerating solution; the other is to make the suspended solids and broken resin accumulated on the surface of the resin follow the backwash water. Discharge, so that the water flow resistance of the exchanger will not become larger and larger. C. The salt solution used for the regeneration of sodium ion exchanger will flow through the failed resin layer at a certain concentration and flow rate to restore the original exchange capacity. D. Sodium ion exchanger replacement (slow cleaning) After the regeneration fluid has been fed, there is still salt solution in the exchanger that has not participated in the regeneration exchange. Use clean water less than or equal to the flow rate of the regeneration fluid for cleaning (slow cleaning). Make full use of the regeneration effect of the salt solution and reduce the load of washing. E. Re-inject water into the regenerant tank and inject the amount of salt water required for the solution regeneration once into the regenerant tank. F. The purpose of the positive washing (quick washing) of the sodium ion exchanger is to remove the regenerated waste liquid remaining in the resin layer. It is usually washed at a normal flow rate until the effluent is qualified. Working principle of automatic boiler water softening equipment: Since the hardness of water is mainly formed and expressed by calcium and magnesium, cation exchange resin (water softener) is generally used to replace Ca2+ and Mg2+ (the main components that form scale) in the water. With the increase of Ca2+ and Mg2+ in the resin, the efficiency of the resin to remove Ca2+ and Mg2+ gradually decreases. After the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to wash the resin layer with salt water in the salt box to replace the hardness ions on the resin, and discharge the resin out of the tank with the regeneration waste liquid. The soft exchange function has been restored. (1) The raw water of the automatic boiler water softening equipment enters the control valve from the water inlet, enters the tank from the top of the valve core, through the valve body, and from the top (or outside of the resin tank center pipe, the same below). Then, it passes downward through the resin layer (this is softened, it is a carbon layer during purification, the same below) to become softened water, which returns to the central pipe through the lower water distributor, up to the valve body, and passes through the valve core from the automatic boiler The water outlet of the softened water equipment is discharged. (2) The raw water of the automatic boiler water softening equipment enters the control valve from the water inlet, enters the tank from the upper part of the valve core, through the valve body, from the lower part of the tank (or central pipe, the same below), the lower water distributor, and then upwards After passing through the resin layer, through the valve body and the valve core, it flows out from the drain port of the automatic boiler water softening equipment. (3) The raw water of the automatic boiler softening equipment enters the control valve from the water inlet, enters the inlet of the nozzle through the valve core, and quickly flows to the nozzle outlet, generating negative pressure, thereby sucking the salt water in the salt tank from the salt suction port The valve body enters the top of the tank. The brine flows downward through the resin layer, passes through the lower water distributor, and upwards along the central pipe. After reaching the valve body and valve core, it is discharged from the drain of the automatic boiler water softening equipment. (4) After the automatic boiler water softening equipment has absorbed all the brine, the raw water continues to enter the control valve from the water inlet, enters the nozzle through the valve core, flows through the nozzle, and passes through the resin layer downwards, and the water distributor , After entering the valve body and spool upwards along the central pipe, it is discharged from the drain of the water softening equipment. (5) The raw water of the automatic boiler softening equipment enters the control valve from the water inlet, enters the nozzle outlet through the valve core, and is injected into the salt tank from the salt suction port; another part of the water flows through the nozzle outlet and passes through the small nozzle The hole flows to the nozzle inlet, and after passing through the valve body and valve core, the sewage of the automatic boiler water softening equipment flows out from the drain. (6) The raw water of the automatic boiler softening equipment enters the control valve through the water inlet, and enters the tank from the top of the valve core through the valve body and from the top. Then, it passes through the resin layer downwards, returns to the center pipe through the lower water distributor, upwards to the valve body, and discharges from the drain port of the automatic boiler water softening equipment after passing through the valve core. Since the hardness of water is mainly formed by calcium and magnesium and expressed because the hardness of water is mainly formed by calcium and magnesium and the principle of sodium ion exchange softening treatment, the raw water is passed through sodium-type cation exchange resin to make the hardness components Ca2+, Mg2+ and The Na+ in the resin phase exchanges, thereby adsorbing Ca2+ and Mg2+ in the water, so that the water is softened.
