Embodiment 1

[0014] Embodiment 1: A kind of mixed-bed resin for condensate polishing of compatible supercritical unit is characterized in that: it is synthesized by the cation exchange resin whose H-type rate must be ≥ 99.9% and the anion-exchange resin whose OH-type rate must be ≥ 95.0%. Mixed operation of powdered ion exchange resin and imported condensate special resin R&H 252H, 900Cl, or DOWEX650C, 550A, or LEWATIT S100, M800. During the mixed operation, the supercritical unit condensate polishing mixed bed operates at a high flow rate above 120m / h. The operating temperature can reach around 70°C. The mixed-bed resin for condensate polishing of the compatible supercritical unit uses styrene and divinylbenzene as processing raw materials, wherein the particle size of the compatible mixed-bed ion-exchange resin is processed to have a specific specific gravity and a specific narrow range of particle size, so that Uniform particle size, functional groups are basically not easy to degrade, ...

Embodiment 2

[0017] Embodiment 2: with reference to attached Figure 1-5 . A mixed-bed resin for condensate polishing in a compatible supercritical unit uses styrene and divinylbenzene as processing raw materials. Uniform particle size, functional groups are basically not easy to degrade, high regeneration degree anion exchange resin is not affected by impurities in the air such as CO 2 Pollution, does not bring in new mechanical impurities and metal ions. It can be used alone in the mixed bed system for supercritical unit condensate polishing, and can be mixed with similar products imported from abroad, with good mixing compatibility.

Abstract

The invention relates to a mixed-bed resin for polishing condensate of a compatible supercritical unit. According to the mixed-bed resin, a mixed-bed ion exchange resin which consists of a cation exchange resin of which the H rate is more than or equal to 99.9 percent and an anion exchange resin of which the OH rate is more than 95.0 percent and resins R&H252H and 900 Cl or DOWEX650C and 550A or LEWATITS100 and M800 which are special for imported condensate, wherein the mixed-bed resin for polishing the condensate of the supercritical unit is run and exchanged at the running temperature of about 70 DEG C at a high flow speed of over 120 meters / hour in the mixed running process. The mixed-bed resin has the advantages that: results of performance tests and on-site application experiments indicate that the performance of the resin for polishing the imported condensate reaches and exceeds the imported condensate polishing resin, and the requirement of on-site running can be met; the mixed-bed resin can replace imported products, and has high compatibility with foreign products; and the mixed-bed resin for polishing treatment the condensate on the supercritical generator unit of over 600 MW is used.

Description

technical field [0001] The invention relates to a mixed bed resin that can be used independently in a mixed bed, and can be mixed with similar products imported from abroad. It has good mixing compatibility and uniform particle size compatibility. It is mainly used for treating a small amount of corrosion products in condensed water in a mixed bed for condensate polishing, and belongs to the field of mixed bed resin manufacturing for condensate polishing. Background technique [0002] Imported condensate special resin Rohm and Haas R&H 252H, 900Cl, or Dow DOWEX650C, 550A, or Lanxess LEWATIT S100, M800, Rohm and Haas R&H 252H, 900Cl are macroporous resins, Dow DOWEX650C, 550A and Lanxess LEWATIT S100 and M800 are gel-type resins, which are mainly used in the high-speed fine treatment mixed bed after high-speed separation and regeneration of wet-cooling units. The resin operates at a normal operating temperature of about 40°C and has good ion exchange capacity. ; The air-cool...
