Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a method for separating harmful substances in white spirit, which comprises the following steps:
first distillation separation: controlling the temperature in the distiller to be a first control temperature so as to separate harmful substances with boiling points lower than the first control temperature; then, controlling the temperature in the distiller to be a second control temperature to separate harmful substances with boiling points higher than the second control temperature, and enabling the white spirit to enter a gas separation process in the form of steam;
gas separation: removing harmful substances such as methanol, lead, plasticizer, sulfur, zinc, free radicals and the like from the white spirit steam through a filter material, condensing the white spirit steam into a liquid state, and entering a liquid separation process;
liquid state separation: removing harmful substances such as methanol, lead, plasticizer, sulfur, zinc, free radicals and the like from the liquor liquid through a filter material, and performing a second distillation separation process;
and (3) second distillation separation: controlling the temperature in the distiller to be a first control temperature so as to separate harmful substances with boiling points lower than the first control temperature; then, controlling the temperature in the distiller to be a second control temperature to separate harmful substances with boiling points higher than the second control temperature, and enabling the white spirit to enter a condensing device in the form of steam, and condensing the white spirit steam to obtain white spirit with separated harmful substances;
wherein the first control temperature is below 75 ℃, and the second control temperature is above 80 ℃.
Wherein, in the first distillation separation, the temperature in the distiller is controlled to be a first control temperature (70-75 ℃) firstly, so as to separate harmful substances with boiling points lower than the first control temperature. Because the boiling point of the effective component ethanol of the white spirit is 77 ℃, when the temperature of the distiller is lower than the first control temperature, harmful substances with the boiling point lower than the first control temperature can be separated out in a gas form, and the effective component ethanol of the white spirit can be continuously kept in the distiller. Then, the temperature in the distiller is controlled to be a second control temperature (80-95 ℃) so as to separate harmful substances with boiling points higher than the second control temperature. Because the boiling point of the effective component ethanol of the white spirit is 77 ℃, when the temperature in the distiller is higher than the second control temperature, the ethanol is evaporated into a gaseous state and enters the gaseous state separation process in the form of white spirit steam, and harmful substances in the white spirit, the boiling point of which is higher than the second control temperature, can still remain in the distiller, so that the primary separation of the white spirit is realized.
After the white spirit steam enters a gas separation process, the white spirit steam passes through a filtering material, and the filtering material can remove harmful substances such as methanol, lead, plasticizer, sulfur, zinc, free radicals and the like, so that secondary separation of the white spirit is realized; meanwhile, after the white spirit steam enters the gas separation process, the temperature is reduced, the white spirit can be condensed into liquid, and the white spirit enters the liquid separation process in the form of white spirit liquid.
After the liquor liquid enters the liquid-state separation process, the liquor liquid passes through the filtering material, and the filtering material can remove harmful substances such as methanol, lead, plasticizer, sulfur, zinc, free radicals and the like, so that the liquor can be separated for the third time.
And (3) the liquor after liquid separation enters a second distillation and separation process, and similar to the first distillation and separation process, the temperature in the distiller is controlled to be the first control temperature (70-75 ℃) at first so as to separate harmful substances with the boiling point lower than the first control temperature. Because the boiling point of the effective component ethanol of the white spirit is 77 ℃, when the temperature of the distiller is lower than the first control temperature, harmful substances with the boiling point lower than the first control temperature can be separated out in a gas form, and the effective component ethanol of the white spirit can be continuously kept in the distiller. Then, the temperature in the distiller is controlled to be a second control temperature (80-95 ℃) so as to separate harmful substances with boiling points higher than the second control temperature. Because the boiling point of the effective component ethanol of the white spirit is 77 ℃, when the temperature in the distiller is higher than the second control temperature, the ethanol is evaporated into a gaseous state and enters the condensing device in the form of white spirit steam, harmful substances in the white spirit with the boiling point higher than the second control temperature still remain in the distiller, and the white spirit steam entering the condensing device is condensed into liquid, so that the white spirit final product with the harmful substances effectively removed is obtained.
The second distillation separation combines together with the first distillation separation, can reach the effect of more effective harmful substance separation.
After the separation method provided by the invention is used for treatment, the content of harmful substances such as formaldehyde, methanol, sulfur, plasticizer, lead, free radicals and the like in the white spirit can be greatly reduced.
In a preferred embodiment, the first controlled temperature is 70 ℃ to 75 ℃, and may be, for example, but not limited to, 70 ℃, 71 ℃, 72 ℃, 73 ℃, 74 ℃, or 75 ℃.
In another preferred embodiment, the second controlled temperature is 80 ℃ to 95 ℃, and may be, for example, but not limited to, 81 ℃, 82 ℃, 83 ℃, 84 ℃, 85 ℃, 86 ℃, 87 ℃, 88 ℃, 90 ℃, 91 ℃, 92 ℃, 93 ℃, 94 ℃ or 95 ℃.
In another preferred embodiment, the filter material includes minerals that adsorb harmful substances such as methanol, lead, plasticizers, sulfur, zinc, free radicals, and the like.
In another preferred embodiment, the filter material comprises activated carbon, which is capable of adsorbing harmful substances such as methanol, lead, plasticizers, sulfur, zinc, free radicals, and the like.
In another preferred embodiment, the filter material further comprises a quantum energy releasing substance capable of ionizing the inert substance so as to be removed by adsorption to minerals or activated carbon.
In addition, the invention also provides the white spirit, which is the ecological safe and healthy white spirit with harmful substances removed according to the separation method, wherein the content of the harmful substances is low, for example, the content of lead ions and methanol is lower than 0.005 mg/mL.
