Description
Technical field
The utility model relates to a kind of sugar juice evaporation device comprising microfiltration systems, belong to Sugar Engineering technical field.
Technical background
In sugar industry, the concentration of the syrup (clear juice) that sugarcane juice obtains after the process of clarification operation is 15.0 ~ 17.0 ° of Bx, and water content is 83.0 ~ 85.0%.Boiling sugar as the syrup containing large quantity of moisture directly sent to, a large amount of steam be consumed, both consumed the energy, extend again the time of boiling sugar.Therefore, the syrup after clarification has to pass through evaporation section, removes a large amount of moisture, is condensed into the syrup of 60.0 ~ 65.0 ° of Bx, then sends to and boil sugar.
During evaporation, sucrose in syrup, reducing sugar and other non-saccharide are divided, under the impact of temperature, pH value and the condition such as concentrated, a series of chemical transformation can be there is, the conversion of such as sucrose and coking, reducing sugar decomposes and non-saccharide analyzes generation incrustation etc., and these chemical transformation can generate more sedimentable matter, bring adverse influence by giving quality, the Sugar Recovery of syrup.Especially the vaporization temperature of an effect evaporating pot and two effect evaporating pots is higher, and chemical reaction is more obvious, and the precipitation of generation is more, and cause syrup inner suspension thing content comparatively large, Viscosity of Syrup is comparatively large, thus affects the quality of syrup, reduces Sugar Recovery.In order to the impurity except syrup after devaporation, current sugar refinery mainly adopts two kinds of methods to solve.The first, before crystallization syrup again after a stove drying and heating, to filter through deep bed filter, thus the suspended substance of precipitation in removing syrup.Second, adopt the method that phosphoric acid floats, in syrup, add lime, phosphoric acid and flocculation agent (polyacrylamide), make it react and generate thick throw out network and suspended substance and the non-sugar impurities of adsorbing syrup, then in syrup, bubble is squeezed into, the throw out making it be formed floats because being subject to larger buoyancy, finally the scum silica frost of floating is removed the object that can reach clarification.Although the two can obtain the good syrup of quality, but the former adds more sulfurous gas in syrup, content of sulfur dioxide in commerieal sugar is often caused to exceed standard, thus reduce the quality even health of harmful to human of commerieal sugar, moreover syrup deposit seeds is tiny, Viscosity of Syrup is higher again, and deep bed filter sealing is difficult to closely, therefore bag filter effect is general all undesirable; And Acrylic Acid Monomer residual in the polyacrylamide entered added by the latter is can by the material of human carcinogen, moreover because the longer meeting of floating interval of floating dock causes sucrose inversion more, and phosphoric acid floating method also can produce more scum silica frost, scum silica frost can take away more sugar, thus also can reduce the rate of recovery of sugar.Therefore, the chemical transformation providing a kind of sugar juice evaporation technique and device to solve because of evaporative process causes the technical problem of syrup degradation to be necessary.
