Abstract
The invention discloses a method for removing the peculiar smell of cooling water and recycling the cooling water in a eucalyptus oil production process. The method is characterized by comprising the following steps of collecting cooling water generated in the eucalyptus oil production process into a collecting pond, and adding a treating agent into the collecting pond, wherein the treating agent is an alkaline solution; then, pumping the cooling water with the treating agent into a vacuum pump cooling water pipe to be recycled as cooling water; sufficiently mixing vacuum pump gas with peculiar smell substances and the cooling water with the treating agent through the high speed rotation of a vacuum pump rotor in the vacuum pump cooling water recycling process; and recovering oily substances in the collecting pond after the collecting pond is used for a period of time. According to the method for removing the peculiar smell of cooling water and recycling the cooling water in the eucalyptus oil production process, the treating agent is added into the cooling water, so that the peculiar smell of the cooling water can be effectively removed, the cooling water can be recycled, the environment is protected, the production cost is reduced, and the benefits of enterprises are increased.
Description
Technical field
The present invention relates to the eucalyptus oil production field, particularly in a kind of eucalyptus oil production process, water coolant is removed peculiar smell removal and reuse method.
Background technology
The blue gum eucalyptus is the general designation that Myrtaceae (Myrtaceae) eucalyptus belongs to (Eucalyptus) seeds, originates in Australian Victoria and Tasmania.Cultivation is introduced in south China and subtropics, the west and south.With cultivation in Yunnan Province, at most, grow best.The essential oil that uses steam method to extract with its branches and leaves is called the blue gum eucalyptus oil.Blue gum eucalyptus oil smell is strongly pungent, and the smell of camphor and cineole is arranged.Mainly for the production of cineole, 80% eucalyptus oil and other spice products.Be raw material take eucalyptus oil, use the method for rectifying to carry out in eucalyptus oil spice product process, in the gas that vacuum is extracted out, contain a small amount of noncondensable gas, this gas has the material of bad smell beastly, with the vacuum pump water coolant, together discharge, enter atmosphere or enter sink drainage by vacuum system, cause that the production environment Air quality is poor, contaminate environment.
Eucalyptus oil manufacturing enterprise is for this problem, and majority is not taken measures, directly discharge.Some Enterprises is by building sewage works, use the way of biological treatment to process, the operational path of processing is: collect the sewage that vacuum pump is discharged, sewage enters waste water processing station, use the technique micro-organism treatment process of anaerobically fermenting, aerobic decomposition, aeration oxidation, by the organic substance decomposing in waste water, be methane, carbon dioxide, enter river after the waste water after processing.But current treatment process is to process method commonly used for organic wastewater, the method, in carrying out essential oil class treatment of Organic Wastewater, exists biochemical treatment efficiency on the low side, and the sewage qualified discharge is difficult for, and needs the investment construction sewage works; Simultaneously, because essential oil belongs to more difficult by the biochemical degradation organism, and biochemical bacterium is had to certain killing action, cause wastewater treatment efficiency poor, sewage can't be accomplished qualified discharge.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide water coolant in the eucalyptus oil production process that can effectively remove water coolant peculiar smell and cooling water circulation use to remove peculiar smell removal and reuse method.
For achieving the above object, the applicant finds unexpectedly by large quantity research, in water coolant, adds the treatment agent of basic solution, can realize removing the effect of peculiar smell, and the basic solution composition do not change, and does not participate in chemical reaction; Its ultimate principle is that the vacuum pump gas that contains smell substance fully mixes with the water coolant that contains treatment agent, under the effect for the treatment of agent, reacts with the low-boiling point material of peculiar smell, changes boiling point into higher, and the material of free from extraneous odour.
Concrete, technical scheme proposed by the invention is: in a kind of eucalyptus oil production process, water coolant is removed peculiar smell removal and reuse method, it is characterized in that: the water coolant in the eucalyptus oil production process is collected in collecting tank, in collecting tank, add treatment agent, described treatment agent is basic solution; The water coolant suction vacuum pump cooling water pipeline that then will contain treatment agent, as cooling water circulation use; In the cooling water circulation use procedure of vacuum pump, by the high speed rotating of vacuum pump rotor, the vacuum pump gas that contains smell substance fully mixes with the water coolant that contains treatment agent; After using for some time, reclaim the oily mater in collecting tank.
Further, described alkaline solution is KOH, NaOH or Na
2CO
3Solution or their mixed solution.
Further, the addition of described treatment agent is the 2-20% of water coolant volume.
Further, described alkaline concentration is 5%-25%.
Adopt technique scheme; in eucalyptus oil production process of the present invention, the water coolant peculiar smell is removed the machine reuse method; by in water coolant, adding treatment agent; cooling water recycling system is installed; can effectively remove the peculiar smell of water coolant, realize recycling of water coolant, not only protect environment; and reduced production cost, increase the benefit of enterprise.
