The utility model discloses a sulfate ion exchanger. The upper end of a tank is provided with a water pipe communicated with the tank inside and the lower end with an acid pipe communicated with the tank inside. The side of the tank is provided with an upper acid pipe, a drainage pipe and a resin pipe communicated with the tank inside. The internal top of the tank is provided with an upper distributor communicated with the water pipe and the bottom end with a lower distributor is communicated with the acid pipe. The internal center of the tank is provided with an acid spraying mechanism communicated with the upper acid pipe and a backwashing mechanism communicated with the drainage pipe. The lower distributor in the tank is provided with quartz sand and resin is arranged between the quartz sand and the acid spraying mechanism. The utility model divides the invalid resin into upper and lower parts to make sulfuric acid generation, with the advantages of no sediment of calcium sulfate in the resin layer, no pollution to resin, low cost of water manufacturing and no corrosion of chloride to the system, thus it can be able to be used and promoted in boiler water supply system.
