A system and method for extracting and separating botanical oils and compounds from botanical material without the use of solvents, having a vaporizing section which is further coupled to a centrifugal electrostatic precipitator for collection and segregation. The vaporizing section receives the botanical material through which a temperature-controlled inert gas is passed to evaporate specific vaporization temperature oils or compounds from the botanical material. The extracted vapor passes to the centrifugal electrostatic precipitator where the oil or compound is reduced back to the liquid state and is collected and segregated. The oils having the lower vapor temperature are collected first and the remaining oils are collected by specific and progressive vaporization temperature control. In some examples, selected vaporized compounds are waste exhausted as vapor by bypassing the centrifugal electrostatic precipitator at specific known vapor temperatures, thereby eliminating potentially toxic or undesirable oils or compounds from being collected.

An axial cyclone air filtration apparatus integrated with a bipolar-charged agglomeration includes a pre-charge region and an axial cyclone coagulation dust separation apparatus, and the pre-charge region is arranged on an air inlet side of the axial cyclone coagulation dust separation apparatus. Suspended particles in air are charged with charges of different polarities in the pre-charge region before entering the axial cyclone coagulation dust separation apparatus. The organic combination of electric coagulation technology and axial cyclone dust separation technology improves the filtering efficiency for ultra-fine particles in air.

An electrostatic filter, for filtering solid and liquid particles in gases composed of a case (3); concentric collectors (15), concentric diffusers (10); electrodes (2); insulated supports (7), distributor disc (8), thermal insulator (17), electrical resistors (4), main collector (9), filter cap (1); the concentric diffusers (10) host along their internal and external wall the electrodes (2); the insulated supports connect the filter cap (1) to the distributor disc (8) which in turn supports the concentric diffusers (10); the electrical resistors (4) are located around the case (3) as clamps and are covered by the thermal insulator (17); so that the gas flows through the filter from the filter inlet (14) located tangentially at the external face of the case (3), towards the insulated outlet (5) located in the central part between the distributor disc (8) and the filter cap (1), thus optimizing the space and surface of the constituent materials and a very high filtration efficiency of liquid and solid micron particles contained in gases at any temperature up to 900 C.

A particle electrical mobility classifier is provided for the classification of particles (e.g., particles less than 1 .Math. in size) based on their electrical mobility. The particle classification zone is curved. In an exemplary embodiment, two metal concentric cylinders, separated by an annular insulation spacer, establish a particle classification zone. A DC electrical field is supplied by the cylinders in the circular classification zone. An example classifier can be operated in different modes such as: (1) as a particle precipitator; (2) as a particle electrical mobility separator, and (3) as a differential mobility classifier. The curved classification zone results in a particle classifier having an extended particle sizing range as compared to their counterparts in classical configurations. The curve of the classification channel (in the flow direction) may be in any of several configurations (e.g., circular, wavy, spiral, or helical).

A system and method for extracting and separating botanical oils and compounds from botanical material without the use of solvents, having a vaporizing section which is further coupled to a centrifugal electrostatic precipitator for collection and segregation. The vaporizing section receives the botanical material through which a temperature-controlled inert gas is passed to evaporate specific vaporization temperature oils or compounds from the botanical material. The extracted vapor passes to the centrifugal electrostatic precipitator where the oil or compound is reduced back to the liquid state and is collected and segregated. The oils having the lower vapor temperature are collected first and the remaining oils are collected by specific and progressive vaporization temperature control. In some examples, selected vaporized compounds are waste exhausted as vapor by bypassing the centrifugal electrostatic precipitator at specific known vapor temperatures, thereby eliminating potentially toxic or undesirable oils or compounds from being collected.
