A cyclonic separation device and a vacuum cleaner including the cyclonic separation device are disclosed. The cyclonic separation device includes a housing and a cyclonic separation device. The cyclonic separation device is provided in the housing to allow dirt in a dust-containing airflow to be separated. The cyclonic separation device includes a first-stage cyclone separator and second-stage cyclone separators located downstream of the first-stage cyclone separator in a flow direction of the airflow. The second-stage cyclone separators surround the first-stage cyclone separator. The first-stage cyclone separator includes an air guide channel and a first-stage cyclone channel surrounding a part of the air guide channel. The dust-containing airflow enters, from the air guide channel, the first-stage cyclone channel for cyclonic separation and then enters the second-stage cyclone separators again through the air guide channel.

A system and method for extracting essential oils from organic material is provided. One embodiment places organic material into an extraction chamber that is a cylindrical wall of rigid material, wherein a diameter and a height of the extraction chamber is sized to define an interior that accommodates a desired amount of an organic material having essential oils; fills the extraction chamber with a solvent after the organic matter has been placed into the extraction chamber; and moves a vortex plunger disposed over the surface of the organic material in a repeated upward and downward motion during an agitation process so that the vortex vanes generate a fluid vortex in the solvent, wherein the fluid vortex causes the solvent to be drawn upward into the organic material and then to be pushed downward through the organic material so that the solvent extracts essential oils from the organic material.

An improved process and apparatus for separating organics and inorganics from waste material with a specific object of preparing the separated organic fraction for the production of biogas or other methods for diverting organics from landfills. Waste material, such as municipal solid waste or source-separated organic waste (SSO), is subjected to a first separation treatment that separates organic and inorganic waste components. The apparatus includes a hopper to receive contaminated organic waste from different sources, a vertical separator that separates the inorganics from the organics by creating a vortex effect in a stationary filtration drum by which the solid contaminants (paper, plastic, metals) are blown in a spiral pattern upwards and removed from the top, while the organic fraction is removed from the bottom. Such apparatus is improved through several methods to reduce or eliminate blockages and their associated downtime, and to increase the efficiency of the separation process.

The present disclosure relates to settling devices for separating particles from a bulk fluid with applications in numerous fields. The particle settling devices of the present disclosure may include a stack of truncoconical cones that may be arranged in opposite orientation, apex to base. Other embodiments include several concentric vertical tubes attached to conical surfaces at the bottom, with inclined settling strips attached to the vertical tubes in annular regions between the tubes. These devices are useful for separating small (millimeter or micron sized) particles from a bulk fluid with applications in numerous fields, such as biological (microbial, mammalian, plant, insect or algal) cell cultures, solid catalyst particle separation from a liquid or gas and waste water treatment.
