A method for reducing dust removal electric field couplings includes the following steps: selecting a ratio between a dust collection area of a dust removal electric field anode and a discharge area of a dust removal electric field cathode to be 1.667:1-1680:1. A dust removal electric field anode and/or dust removal electric field cathode size is selected so that the number of electric field couplings is less than or equal to 3. The number of electric field couplings is reduced, electric field energy consumption is low, electric field coupling consumption for an aerosol, water mist, oil mist and loose smooth particulate matter is reduced, and electric field energy is saved.

The aerosol particulate matter collecting device includes a shell, a first electric field component, a second electric field component and the collection unit. The first electric field component is connected to the shell and forms a first electric field area, the second electric field component is connected to the shell and forms a second electric field area, the second electric field component includes a first plate and a second plate, and the electric property of the first plate is opposite to that of the first electric charges; a bottom plate of the collection unit is located between the first plate and the second plate, protrusions are arranged on the bottom plate, a flow channel for accommodating collecting liquid is formed in the bottom plate, the protrusions are configured to enable the flow channel to extend along a curve.

A filter system includes a body having an inlet and an outlet fluidly coupled with the inlet by one or more passageways. The one or more passageways are shaped to direct a fluid having particles through the body from the inlet toward the outlet. The one or more passageways may rotate the fluid in one or more cyclonic directions. A lattice component is disposed within the passageways and includes one or more openings through which the fluid passes as the fluid moves in the one or more cyclonic directions. The passageways are shaped to remove a first portion of the particles from the fluid, and the lattice component is shaped to remove a second portion of the particles from the fluid such that the fluid exiting from the body via the outlet has fewer of the particles than when the fluid entered the body via the inlet.

Atmospheric pollutants are efficiently separated from exhaust gas with low operating cost. The exhaust gas cleaning method forms a fine mist of aqueous alkaline solution with an atomizer in an atomizing step; mixes the aqueous alkaline solution mist with exhaust gas to absorb atmospheric pollutants contained in the exhaust gas into the mist in a mixing step; and separates mist that absorbed atmospheric pollutants from the exhaust gas in a separating step.

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.
