Background technology
At present, be applied to chemical industry, concentration for sulfanilamide (SN) mother liquor after sulfanilamide (SN) chemical reaction is carried out concentration, generally evaporimeter and the direct-type steam pipe coil of conventional simple-type are used in conjunction with, coiled concentration evaporator carries out concentration and evaporation to mother liquor, in some areas, may arrive reason due to the priority of heat-transfer effect, causes certain part to be heated too high, and make solution boiling, produce foam and trickle out.And this operation is controlled unstable to the sulfanilamide (SN) concentration after concentrated, efficiency is low, cost is high.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of energy consumption is low, easy to control, the Three-effect concentration evaporator of stable operation.
The present invention solves the technical scheme that its technical problem takes: a kind of Three-effect concentration evaporator that sulfanilamide (SN) solution is carried out to evaporation and concentration, and main body is mother liquor pond and hydrolytic tank, described mother liquor pond connects end entrance on 1st effective evaporator by 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 an effect separator import; One effect separator outlet connects pump two, and pump two connects the upper 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 effect separator imports, and two effect separator outlets connect pump three, and pump three connects end entrance on 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 triple effect separator; The left outlet of triple effect separator lower end connects pump four, and pump four connects the import of triple effect evaporator upper end, and the right outlet of triple effect separator lower end connects hydrolytic tank.
For more effective by the moisture vapor in mother liquor in bottom condensation separation out, the outside of described 1st effective evaporator, 2nd effect evaporator and triple effect evaporator bottom is connected with condensate pipe by canoe.
For mother liquor is separated with water evaporation in auxiliary evaporator, the outside on described 1st effective evaporator, 2nd effect evaporator and triple effect evaporator top is connected with steam pipe by canoe.
The beneficial effect of structure of the present invention is: adopt after this structure, during moisture in evaporation in separated mother liquor, can effectively utilize heat energy, reduce energy consumption, reduced production cost.This project organization convenient operation, the utilization rate of mother liquor is greatly improved.
accompanying drawing explanation:
Fig. 1 is connection diagram of the present invention;
In 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, an effect separator 4-2, two effect separator 4-3, triple effect separator 5, hydrolytic tank.
The specific embodiment
A kind of Three-effect concentration evaporator that sulfanilamide (SN) solution is carried out to evaporation and concentration of Fig. 1, main body is mother liquor pond 1 and hydrolytic tank 5, described mother liquor pond 1 connects the upper end entrance of 1st effective evaporator 3-1 by pump one 2-1; 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 an effect separator 4-1 import; One effect separator 4-1 outlet connects pump two 2-2, and pump two connects the upper 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 effect separator 4-2 imports, and two effect separator 4-2 outlets connect pump three 2-3, and pump three 2-3 connect the upper end entrance of triple effect evaporator 3-3; 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 left outlet in 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 described 1st effective evaporator 3-1,2nd effect evaporator 3-2 and triple effect evaporator 3-3 bottom is connected with condensate pipe by canoe.By pouring into the mobile cold water of condensate pipe, reduce the temperature of base of evaporator, make after the water cooling of gaseous state, with liquid form, enter after separator separated.
The outside on described 1st effective evaporator 3-1,2nd effect evaporator 3-2 and triple effect evaporator 3-3 top is connected with steam pipe by canoe.In auxiliary evaporator, mother liquor is separated with water evaporation, the steady temperature of moisture separated part in maintenance evaporimeter mother liquor.
