Embodiment Construction

[0019] In the embodiment of the present invention, the pressure polishing treatment system for condensed water adopts two 600MW subcritical units. The two sets of condensate water pressure fine treatment systems of the 2 units are manufactured by the American GRAVER company. Each system is equipped with three medium-pressure high-speed mixed beds, each of which can treat 50% of the condensed water. Automatically for program control. The designed treatment flow rate of the mixed bed is 900m 3 / h, designed to withstand a pressure of 4.0MPa, operating pressure of 2.6 ~ 2.8MPa.

[0020] The mixed resin used for mixing in the mixed bed includes two special resins for condensate polishing with sub-uniform particle size. The first resin is Ambersep252H resin and Ambersep900Cl resin from American R&H Company; the second resin is Zhejiang Zhengguang Industrial Co., Ltd. ZGC900(H) resin and ZGA600(OH) resin. The physical and chemical properties of 252H resin, ZGC900(H) resin, 900Cl r...

Abstract

The invention discloses a mixed resin for a medium-pressure precision processing mixed bed of condensed water. The mixed resin comprises two monosphere resins special for precision processing on the condensed water, wherein the first resin is 252H type resin and 900CI type resin produced by American R&H Company; and the second resin is ZGC900 type resin and ZGA600 type resin produced by Zhejiang Zhengguang Industry Co. Ltd. The resin is simple in principle and convenient to operate. The application of the resin brings great convenience to companies. The resin does not affect the quality of effluent and the regeneration quality. Operation and regeneration equipment and system do not need any change, so no any additional cost is caused.

Description

technical field [0001] The invention relates to a mixed resin, in particular to a mixed resin used for pressure finishing mixed beds in condensed water. Background technique [0002] In the condensate water pressure polishing treatment system, most of the ion exchange equipment for removing dissolved salts in water need to use high-speed mixed-bed resin. High-speed mixed bed resin is composed of strong acid cation resin and strong basic anion resin. [0003] Because the high-speed mixed bed resin is in the high pressure and fast flow environment of the condensate water pressure finishing system, and after running in the mixed bed, it needs to go through separation, regeneration and other treatment procedures, so this type of resin must have high resistance. Osmotic impact strength, anti-oxidation stability, uniform particle size distribution and low leachable content are high-end products in ion exchange resins for water treatment. At present, the condensate water pressure...
