[0003] The existing volatile oil extraction equipment structure as shown in Figure 1 It mainly covers extraction tank, oil-water rheometer, primary condenser, secondary condenser, oil-water separator, cooling water pipeline and other components.Volatile oil is heated and evaporated in the extraction tank, the oil-water rheometer plays the role of preliminary processing mixed flow state in the whole equipment, the primary condenser and the secondary condenser work cooperatively in turn, cool the mixed steam, when the mixed steam containing volatile oil enters the condenser, heat exchange is carried out with the cooling medium (usually cold water), the temperature of the steam is reduced, because the steam changes phase when cold, changes from gaseous state to liquid state, so that the condensation collection of volatile oil is realized.The oil-water separator carries out efficient separation to the oil-water mixture formed after condensation, and the relatively pure volatile oil product is obtained.The cooling water pipeline constructs the connection network of the whole cooling circulation system, connects the cooling water of the factory cooling tower and the primary / secondary condenser closely, so that the circulating water cooled by the cooling tower can circulate in the primary / secondary condenser, takes away the heat of the mixed steam, and promotes the condensation of volatile oil steam into liquid state for collection.

[0004] The cooling tower is a device that realizes heat dissipation through heat and humidity exchange of water and flowing air, and in the high temperature period of summer, due to the increase of ambient temperature, the temperature of the extraction cooling tower water also rises greatly.This directly leads to the higher temperature of the cooling water circulating to the condenser, so that the temperature inside the condenser exceeds the ideal condensation temperature range of volatile oil steam, a large amount of volatile oil steam cannot be condensed in time and is lost in gaseous form in the air, which seriously reduces the collection amount of volatile oil, causes the waste of raw materials and the decline of production benefit.

[0005] Therefore, it is necessary to optimize and improve the cooling link in the volatile oil extraction process, to improve the extraction efficiency and collection amount of volatile oil. UTILITY MODEL CONTENT

When the temperature sensor 5 detects that the temperature of the circulating water is higher than the preset upper limit temperature, the second switch valve 7 on the second pipeline 4 is opened, and the first switch valve 6 of the circulating water pipeline 3 is closed at the same time, and the second cold water source starts to flow into the secondary condenser to replace the circulating water for heat exchange; the temperature of the second cold water source ensures that the condenser can effectively reduce the temperature of the mixed steam to realize the rapid condensation of the volatile oil. When the detected circulating water temperature drops below the preset lower limit temperature, the first switch valve 6 of the circulating water pipeline 3 is reopened, and the second switch valve 7 on the second pipeline 4 is closed at the same time, and the circulating water starts to flow into the condenser again, so that the circulating water system is fully utilized, the consumption of municipal tap water is reduced, and the purpose of saving water is achieved.
