Liquid alkali, process water and cyanuric acid are added into the salt forming reactor in proportion. Fully mix well. After the cyanuric acid is completely dissolved, it is pumped by the trisodium salt filter pump to the plate and frame filter press for filtration to remove the insoluble impurities in the trisodium salt. The filtered trisodium salt solution enters the trisodium salt storage tank for standby.
Add some clean water into the chlorination reactor and start the chlorination reactor for stirring.
Turn on the chilled brine to control the temperature in the reactor, and turn on the chlorine gas in the reactor appropriately. When the pH value in the reactor meets the requirements, turn on the trisodium salt circulating pump to pump the pre cooled trisodium salt to the trisodium salt absorption tower. The trisodium salt flows to the chlorination reactor by itself from the bottom of the absorption tower. The trisodium salt and chlorine gas react quickly in the chlorination reactor to generate trichloroisonuric acid, which overflows to the trichloro transfer tank from the overflow port of the chlorination reactor.
The ratio of trisodium salt flow to chlorine flow is controlled for continuous feeding reaction, and the generated trichloride flows out of the overflow port continuously and is pumped to the trichloride slurry storage tank by the trichloride feeding pump.
After the material reaches a certain amount, open the valve to add the material into the trichloro filtration centrifuge, separate the solid from the mother liquor, wash, dehydrate, dry, quantitatively pack or granulate and then pack it into finished products.
