Camphorwood vaporization water vapor drying and essential oil and waste heat recycling device and using method

Abstract

The invention discloses a camphorwood vaporization water vapor drying and essential oil and waste heat recycling device and a using method. The camphorwood vaporization water vapor drying and essential oil and waste heat recycling device comprises a high-temperature drying chamber, an essential oil and waste heat recycling assembly and a heat source assembly. A drying chamber door is arranged at the front end of the high-temperature drying chamber. Cooling fin assemblies and steam-injection assemblies are arranged in the high-temperature drying chamber. Bottom rails and condensed water recycling channels are formed in the bottom of the high-temperature drying chamber. A fan assembly is arranged on the upper portion of one side of the high-temperature drying chamber, and a micro-pressure self-discharging assembly extending to the outside is arranged on the upper portion of the other side of the high-temperature drying chamber. The essential oil and waste heat recycling assembly is connected with the condensed water recycling channels and the micro-pressure self-discharging assembly. The heat source assembly is connected with the essential oil and waste heat recycling assembly and the cooling fin assemblies. The using method comprises the following steps that S1, camphorwood is put in the drying chamber; S2, high-humidity preheating is conducted; S3, drying is conducted, and essential oil and waste heat are recycled; S4, cooling treatment is conducted; S5, high-humidity balance treatment is conducted; and S6, the camphorwood is taken out of the drying chamber. The camphorwood vaporization water vapor drying and essential oil and waste heat recycling device and the using method have the advantages that the drying period is short, emission of waste gas is avoided, and the camphorwood essential oil and the drying waste heat can be recycled.

Description

technical field [0001] The invention mainly relates to camphor wood drying and its essential oil recovery technology, in particular to a camphor wood vaporized water vapor drying device and a method for recovering essential oil and waste heat. Background technique [0002] Camphor tree is a precious material and special economic tree species in southern China. Because of its excellent material, beautiful texture, smooth planing surface, suitable for carving, and has the characteristics of corrosion resistance and insect resistance, camphor wood is a high-end bookcase, wardrobe and craft decorations. of high-quality raw materials. The axial parenchyma and ray tissue of camphor wood are rich in oil cells, and its camphor oil content can reach 3-5%. Camphor oil includes a variety of chemical components, including camphor, eucalyptol, sassafras ether, camphor alcohol, camphorone, α-pinene, camphene, lignin, etc., wherein α-pinene and camphene are synthetic insecticides. An imp...
