1. Process Brief
The liquid alkali, process water and cyanuric acid are added into the salifying reactor in proportion and fully mixed. 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 a certain amount of clean water to the chlorination reactor, start the chlorination reactor for mixing, start the frozen brine to control the temperature in the reactor, and at the same time, properly start the chlorine in the reactor. When the pH value in the reactor meets the requirements, start the trisodium salt circulating pump to pump the pre cooled trisodium salt to the trisodium salt absorption tower, and the trisodium salt flows to the chlorination reactor by itself from the bottom of the absorption tower, Trisodium salt and chlorine react rapidly in the chlorination reactor to generate trichloroisonuric acid, which overflows from the overflow port of the chlorination reactor to the trichloro transfer tank, controls the ratio of trisodium salt flow to chlorine flow for continuous feeding reaction, and the generated trichloro continuously flows out from the overflow port and is pumped to the trichloro slurry storage tank by the trichloro 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 the product.
