Softened water treatment system and method

Abstract

The invention relates to the field of treatment of industrial water and provides a softened water treatment system. The system comprises a salt tank, a softened water treatment device, a plurality of softening water tanks, a heat exchanger, a steam boiler, an external to-be-cooled device and an internal l to-be-cooled device, wherein the softened water treatment device is connected with the salt tank through a first valve, the softened water treatment device is respectively connected with the softening water tanks through a plurality of second valves, one or more softening water tanks feed the softened water into the to-be-cooled devices through one or more pumps, and the softened water heated by the to-be-cooled devices enters into one or more softening water tanks or the softened water after heat exchanger enters into one or more softening water tanks. One or more softening water tanks feed the softened water to the heat exchanger through one or more pumps and feed the softened water after heat exchange by the heat exchanger to the steam boiler, steam output by the steam boiler is fed to the to-be-cooled devices and the softened water cooled by the to-be-cooled devices enters into one or more softening water tanks.

Description

technical field [0001] The invention relates to the field of industrial water treatment and provides a softening water treatment system and method. technical background [0002] The steam boiler is an important equipment for generating steam. Before it is put into operation, the boiler water needs to be softened until it is qualified to enter the steam boiler to generate steam. In most factories that use boilers, the outlet pipe of the softened water treatment equipment is directly connected to the softened water tank, and a common problem in the initial stage of preparing softened water is that the quality of the softened water is not up to standard, so it is necessary to treat the water in the softened water tank Repeated flushing and discharge until qualified. [0003] In addition, during the actual use of the steam boiler, the softened water in the softened water tank is preheated first, and the softened water is preheated to a certain temperature, about 40°C.
