A hybrid humidity control and air purification device and method for hybrid humidity control and air purification. The hybrid device is a single unit capable of humidifying dry environmental air, dehumidifying humid environmental air and removing particulates and contaminants from the air. The device controls the outgoing air to a relative humidity setpoint between 35-50% with negligible particulate matter content. Particulate matter is transferred to water, which may be supplied and flushed by an automatic water pumping system.

Clean, safe and efficient methods, systems, and processes for utilizing thermolysis methods to processes to convert various e-waste sources into Clean Fuel Gas and Char source are disclosed. The invention processes e-waste sources, such as for example whole circuit boards, to effectively shred and/or grind the waste source, and then process using thermolysis methods to destroy and/or separate halogen and other dangerous components to provide a Clean Fuel Gas and Char source, along with the ability to recover precious metals and other valuable components from the Char.

Various embodiments include composite wicks for ultra-low noise condensation particle counters (CPCs). In one embodiment, a composite wick includes a first porous material having a first pore density, with the first porous material further having a first surface and an opposing second surface. A second porous material is in fluid communication with the first porous material and has a first surface with an area substantially the same as an area of the first surface of the first porous material. The first surface of the second porous material is substantially in contact with the first surface of the first porous material. The second porous material has a pore density that is dissimilar the first pore density of the first material. The first material and the second material are configured to provide vapor from a liquid to a fluid-based particle counter. Other apparatuses are disclosed.

A system for removing dust from exhaust gas, comprising a dust removing system inlet, a dust removing system outlet, and an electric field apparatus (1021). The electric field apparatus (1021) comprises an electric field apparatus inlet, an electric field apparatus outlet, a dust-removing electric field cathode (10212) and a dust-removing electric field anode (10211). The dust-removing electric field cathode (10212) and the dust-removing electric field anode (10211) are used to generate an ionizing electric field for dust removal. When a certain amount of dust has accumulated on the electric field apparatus, the electric field apparatus performs a black carbon removal process, thereby avoiding a reduced electrode gap resulting from an increased thickness of black carbon.

An effluent processing device includes an input port to receive an effluent mixture containing air, oil, and water. One or more baffles are positioned between the input port and at least one air outlet to deflect the effluent mixture to assist in separating the oil and the water from the air. A member positioned below the one or more baffles selectively allows only oil of the separated oil and water to pass from a first side of the member through openings in the member to a second side of the member. A sump is arranged to receive and retain the oil on the second side of the member as the oil passes from the first side to the second side. The effluent processing devices includes at least one air outlet through which air is exhausted to atmosphere.

A method that can efficiently dissolve a water-soluble component contained in a gas with smaller energy consumption is provided. A mist is produced from a liquid. The mist and carrier air is mixed to produce mist-containing air. A solution gas and the mist-containing air are supplied to a static mixer. The solution gas and the mist-containing are mixed by using the static mixer. The liquid mist is brought in contact with the solution gas to dissolve a water-soluble component that is contained in the solution gas into the liquid mist. The liquid mist that contains the water-soluble component dissolved aggregates and produces a solution that contains the water-soluble component dissolved.

A negative-pressure dust collector system employs a dust separator device to separate the dust that is entrained in a stream of dust-laden air, exhausts the air stream to a vacuum-inducing machine, and discharge the separated dust downward into a bagger arrangement. The latter employs an open-bottom generally rigid hopper with a grid across its open bottom. A flexible dust collection bag is clamped onto an exterior of the hopper and hangs from the hopper. Under vacuum, the bag closes off the open bottom of said hopper. The grid has openings dimensioned so that dust in the container passes freely through the grid when the vacuum-inducing machine is shut off, but so that the bag may be sucked up against the grid, but not sucked into the open-bottom hopper when vacuum is applied. A flexible apron may be attached to the bottom of the hopper between the grid and the dust-collection bag.

An engine exhaust gas treatment system, comprising an exhaust gas dust removal system and an exhaust gas ozone purification system. The exhaust gas dust removal system comprises an exhaust gas dust removal system inlet, an exhaust gas dust removal system outlet, and an exhaust gas electric field apparatus (1021). The exhaust gas electric field apparatus (1021) comprises an exhaust gas electric field apparatus inlet, an exhaust gas electric field apparatus outlet, an exhaust gas dust removal electric field cathode (10212), and an exhaust gas dust removal electric field anode (10211). The exhaust gas dust removal electric field cathode (10212) and the exhaust gas dust removal electric field anode (10211) are configured to produce an exhaust gas ionized dust removal electric field. The engine exhaust gas treatment system is able to effectively remove particles in engine exhaust gas, and the purification treatment effect for engine exhaust gas is good.

An air dust removal method, comprising the following steps: 1) using an ionization dust removal electric field to adsorb particulate matters in intake air; and 2) using the ionization dust removal electric field to charge an intake air electret element. The method can effectively remove dust in air, the dust removal ability is better, and the dust removal efficiency is higher.
