The present invention solves the technical scheme that its technical problem takes: a kind of sulfanilamide (SN) solution is carried out the triple effect concentration evaporator of evaporation and concentration, main body is mother liquor pond and hydrolytic tank, and said mother liquor pond connects end entrance on the 1st effective evaporator through pump one; The outlet of 1st effective evaporator right-hand member connects the import of 2nd effect evaporator left end, and the outlet of 1st effective evaporator lower end connects one and imitates the separator import; One imitates separator outlet connects pump two, and pump two connects the last end entrance of 2nd effect evaporator; The outlet of 2nd effect evaporator right-hand member connects the import of triple effect evaporator left end, and the outlet of 2nd effect evaporator lower end connects two and imitates the separator import, and two imitate separator outlet connects pump three, and pump three connects end entrance on the triple effect evaporator; The outlet of triple effect evaporator right-hand member connects hydrolytic tank, and the outlet of triple effect evaporator lower end connects the triple effect separator; The outlet of a triple effect separator lower end left side connects pump four, and pump four connects triple effect evaporator upper end import, and the right outlet of triple effect separator lower end connects hydrolytic tank.
For more effective with the moisture vapor in the mother liquor in the bottom condensation separation come out, the outside of said 1st effective evaporator, 2nd effect evaporator and triple effect evaporator bottom is connected with condensate pipe through canoe.
In order in the auxiliary evaporator mother liquor to be separated with the water evaporation, the outside on said 1st effective evaporator, 2nd effect evaporator and triple effect evaporator top is connected with steam pipe through canoe.
The beneficial effect of structure of the present invention is: after adopting this structure, when evaporation separates the moisture in the mother liquor, can effectively utilize heat energy, reduce energy consumption, reduce production cost.This project organization is convenient to operation, and the utilization rate of mother liquor is greatly improved.
Description of drawings:
Fig. 1 is a connection sketch map of the present invention;
Among the figure: 1, mother liquor pond 2-1, pump one 2-2, pump two 2-3, pump three 2-4, pump four 3-1,1st effective evaporator 3-2,2nd effect evaporator 3-3, triple effect evaporator 4-1, are imitated separator 4-2, two and are imitated separator 4-3, triple effect separator 5, hydrolytic tank.
The specific embodiment
Fig. 1 is a kind of to carry out the triple effect concentration evaporator of evaporation and concentration to sulfanilamide (SN) solution, and main body is mother liquor pond 1 and hydrolytic tank 5, and said mother liquor pond 1 connects 1st effective evaporator 3-1 through pump one 2-1 and goes up end entrance; The outlet of 1st effective evaporator 3-1 right-hand member connects the import of 2nd effect evaporator 3-2 left end, and the outlet of 1st effective evaporator 3-1 lower end connects one and imitates separator 4-1 import; One imitates separator 4-1 outlet connects pump two 2-2, and pump two connects the last end entrance of 2nd effect evaporator 3-2; The outlet of 2nd effect evaporator 3-2 right-hand member connects the import of triple effect evaporator 3-3 left end, and the outlet of 2nd effect evaporator 3-2 lower end connects two and imitates separator 4-2 import, and two imitate separator 4-2 outlet connects pump three 2-3, and pump three 2-3 connect triple effect evaporator 3-3 and go up end entrance; The outlet of triple effect evaporator 3-3 right-hand member connects hydrolytic tank 5, and the outlet of triple effect evaporator 3-3 lower end connects triple effect separator 4-3; The outlet of a left side, triple effect separator 4-3 lower end connects pump four 2-4, and pump four 2-4 connect triple effect evaporator 3-3 upper end import, and the right outlet in triple effect separator 4-3 lower end connects hydrolytic tank 5.
The outside of said 1st effective evaporator 3-1,2nd effect evaporator 3-2 and triple effect evaporator 3-3 bottom is connected with condensate pipe through canoe.Through pouring into the condensate pipe flowing cold water, reduce the temperature of base of evaporator, the water-cooled that makes gaseous state but after, get into behind the separator separated with liquid form.
