Formaldehyde is pumped into the tank by a formaldehyde pump. When the liquid level of the reaction tank reaches the reaction level, it starts the reacting pump with a complete set of equipment and returns to the tank after the reactor and the plate cooler, and the liquid ammonia is steamed into the liquid ammonia evaporator placed in the reacting tank after the valve is controlled. The vaporized vapor enters the steam ammonia filter for filtration, and the filtered steam and ammonia enter the tube of the retropion reactor (the reactor is the tube shell reactor and the reactor shell chilled water) reacts with the plate cooler after the reaction in the tropics, and the reaction end of the reacting liquid is up to 9.3. The production of the retropion reacting liquid is put into the intermediate storage tank for 24 hours after the storage circulation pump is put into the tank, then it is a reserve of the qualified reaction liquid, and the circulation pump is used to store the circulation pump.
The qualified reaction liquid is evaporated with one effect continuous evaporator with one effect feed pump. The one effect gas phase is pumped by a vacuum pump to the water tank after one effect vacuum condenser condenses, and the gas phase is emptying, and the waste water overflow to the ditch. One effect liquid phase is evaporated by the two effect feed pump into two effect continuous evaporator. The two effect gas phase is pumped into the water tank by the two effect vacuum pump after the two effect vacuum condenser condenses. The gas phase goes to the air and the waste water overflow to the ditch. The two effect liquid phase is evaporated and crystallized by the crystallization tank feeding pump into the crystallization tank. The gas phase of the crystallization tank is pumped into the water tank by the vacuum pump of the crystallization tank, and the gas phase is emptied and the waste water overflow to the ditch.
The material in the crystallization tank is centrifuged by the centrifuge pump and the other part is returned to the crystal tank trough along the tangent direction as the reflux liquid. After the mother liquid enters the mother liquid trough, the mother liquid is pumped into the mother liquid pump for two effect and is recycled. The discoloured mother liquid is decoloured by the mother liquid pump into the decolorization tank and returns to the mother liquid trough after the filter press. . The dry material from the centrifuge is sent into the pneumatic dryer through the screw feeder to dry, and the dried product is packed. The exhaust gas of the dryer enters the absorber dust in the tail gas absorption tower, and the tail gas after absorption enters the atmosphere. The absorption liquid is circulate by the exhaust absorption circulating pump. When the absorption liquid reaches a certain concentration, it is put into the mother liquid trough, and the desalted water is supplemented when the liquid level of the absorption tower is low.
