Each unit of the desalting system adopts an ion exchange desalting process, a 2 multiplied by 100 percent capacity fine treatment high-speed mixing bed is arranged, and the two fine treatment high-speed mixing beds run one by one and are standby one by one, so that the desalting system has the advantages of saving system equipment investment and construction and installation cost, reducing occupied area, reducing operation and maintenance workload and the like.
Example 2
The invention discloses a condensate fine treatment system of a large H-level peak-shaving gas-steam combined cycle direct-current waste heat boiler, and with reference to fig. 1, the condensate fine treatment system comprises a strong magnetic iron removal filter 1, a fine treatment high-speed mixing bed 2, a resin catcher 3 and a recirculation pump 4.
