Background technology
Acesulfame potassium is a kind of food additive, has the function increasing food sweet taste, in good taste, empty calory, and at human body
Inside not metabolism, do not absorb, good to heat and absolute acid stability, it is forth generation synthetic sweetener on our times.The production work of acesulfame potassium
Skill is simple, and cheap, superior performance, it is considered to be one of the most promising sweeting agent, is widely used in various food
In production.Along with the increase of acesulfame potassium usage amount, the intractability of its filtrate is consequently increased.At present, both at home and abroad to acesulfame potassium
Processing of filtrate mainly uses two traditional effect concentration method and MVR enrichment facility new techniques.And two traditional effects are dense
Contracting processing method needs to carry out being concentrated to by filtrate crystallization, then processes through the mode of decrease temperature crystalline and separation, profit
Reclaiming acesulfame potassium by the method, steam consumption is big, and in the acesulfame potassium of recovery, impurity content is high, often needs to carry out at secondary refining
Reason.Two effect concentration methods often evaporate 1 ton of water, take around consumption steam about 0.8 ton, and energy resource consumption is relatively big, Er Qienong
During contracting temperature required higher, easily cause material decompose.And MVR enrichment facility new technique is a kind of emerging technology, this technology pair
The high treating effect of acesulfame potassium filtrate, but in this technology, the device of application is expensive, and then make being processed into of acesulfame potassium filtrate
Originally dramatically increase.

The temperature of tank stock solution rises to preset temperature, and arrange entering film and going out film pressure in film device is 15~30kg simultaneously, treats stock solution temperature
Degree opens the outlet valve of filtrate tanks and the imported valve of film device after reaching preset temperature, makes stock solution enter film device,
Being carried out through concentrating by the membranous system in film device, the passing through of organic membrane in membranous system, film clear liquid flows to clear liquid storage tank again
Recycle;
S3: when the film clear liquid flux in film clear liquid storage tank drops to 20~60L/PM, to the circulating tank filling film dope
The water of interior addition isodose is dialysed, and acesulfame potassium is dialyzed out and flows to collecting tank and recycles;
S4: in circulating tank, remaining residual liquid is directly discharged to liquid waste processing center and carries out liquid waste processing;
S5: be carried out film device and detect, i.e. completes whole acesulfame potassium filtrate and processes operation after having detected.
Preferably, the hot water circulation heated that the hot water cyclesystem in described S2 step uses temperature to be 60~90 DEG C.
Preferably, the organic membrane that the organic membrane in described S2 step uses molecular weight to be 800~1200.
