Ion exchange device and condensed water fine processing equipment

Abstract

The invention relates to the field of condensed water fine processing, and discloses an ion exchange device and condensed water fine processing equipment. The ion exchange device comprises a pot body. A cavity of the pot body is provided with a water inlet and a water outlet. A positive resin layer drained water collection device and a negative resin layer drained water collection device are arranged in the cavity in the axial direction of the pot body in a separated mode and located between the water inlet and the water outlet. A negative resin layer is arranged in the negative resin layer drained water collection device, so that condensed water can penetrate through the positive resin layer drained water collection device and the negative resin layer drained water collection device after entering the cavity through the water inlet and then is drained from the water outlet. The ion exchange device has the effects that resin regeneration operation is easy, and a pipeline system is simplified.

Description

technical field [0001] The invention relates to the field of condensate fine treatment, in particular to an ion exchange device and condensate fine treatment equipment. Background technique [0002] Condensed water generally refers to the water that is cooled and condensed by the condenser after the steam generated by the boiler has done work. As for the condensate cooling method, it is realized by using a wet-cooled generator set or an air-cooled generator set. Among them, compared with wet-cooled generator sets, although there is no risk of a large amount of ion impurities being brought into the condensed water by the cooling water leakage of the wet-cooled generator set, it has high temperature, high iron content, and air leakage. The characteristics of oxygen and high carbon dioxide content, therefore, the selection of condensate polishing process is different from that of wet-cooled generating units. For the fine treatment of air-cooled generator sets, powder resin fi...

Problems solved by technology

[0003] Since the mixed bed needs to separate the invalid cation resin and anion resin and then regenerate the cation resin and the anion resin respectively, the regeneration operation is complicated and if the separation of the cation resin and the anion resin is not complete, the mixed bed after regeneration There will be a large amount of sodium-type and chlorine-type resins in the bed, which makes the regeneration of anion and anion resins in the mixed bed low

Compared with the mixed bed, the cation-yin separation bed has the advantages of simple regeneration operation and flexible operation mode, but the previous yang-yin separation bed is to place the cation resin and the anion resin in separate exchangers, so the same processing capacity In this case, the yang-yin separation bed occupies a larger area than the mixed bed, and the pipeline valve structure is also more complicated.
