An ionization chamber is provided with a series of parallel plates spaced from each other and with holes passing therethrough. Alternating plates have either a highest high voltage or a lower high voltage provided thereto, such as through a DC transformer coupled to an electric power source. Holes in alternating plates are preferably offset so that airflow through the plates occurs along curving pathways. The plates are sufficiently highly charged to cause carbon dioxide to be ionized and for carbon ions to become trapped within wells defining lowest regions of electric charge within an electric field inside the ionization chamber. Fans control airflow through the ionization chamber. A dehumidifier is provided upstream of the ionization chamber to reduce moisture content within the incoming gas. After the carbon has collected within the wells, harvesting of the carbon ions as carbon nano particle powder can occur within a carbon cache.

A method for designing one part of an electrostatic separating device of a mixture of different material granules, the method including providing a sorting performance value to be met by the device when at least one predefined mixture is introduced into the device to be sorted, optimizing a value of at least one parameter of the set of parameters relating to the device part by using an optimization technique, the optimization technique including the use of a sorting performance model of the device, and the optimization technique occurring under the constraint that the sorting performed by the device has the given sorting performance value.

A portable air purifier device includes a fan, air purification system, air quality sensor module, air crossflow limiter and a head mount. The air purifier is mounted in the forehead/head area without blocking the user's nose, mouth or face area, making it easy to breathe. The air purification system consists of one or more Electrostatic Precipitators connected together, in series to achieve higher level of air purification efficiency or in parallel to achieve higher output air flow rate. The crossflow limiter blocks dirty air from the outside from displacing the cleansed air supplied by the device. The air quality sensor module automatically throttles the air purification up/down based on the air pollution level surrounding the user. The head mount is used to easily mount the air purifier device either directly onto the user's head or on top of any head-wear such as a helmet or a hat.

The present invention relates to a computer-implemented method for monitoring at least one exhaust gas purification system for purifying an exhaust gas stream to be purified of an industrial system or an industrial process. The method comprises retrieving system data of the exhaust gas purification system from a data cloud. The system data stored in the data cloud were at least partially received beforehand by the data cloud from the exhaust gas purification system. The system data relate to at least measurement data of at least one sensor of the exhaust gas purification system and/or data about at least one adjustable parameter of the exhaust gas purification system. The method further comprises determining at least one quantity characterizing the exhaust gas purification system based on the retrieved system data.

A biosensor of the present invention comprises: a first microelectrode and a second microelectrode arranged to intersect in a comb shape on a substrate; and a plurality of receptors fixed in a space between the microelectrodes to specifically react with a target biomaterial. In particular, a micropattern of a conductive material is formed in the space between the microelectrodes. Accordingly, greater electric field intensity can be obtained compared to a biosensor without micropatterns, thereby concentration of the target biomaterial using dielectric electrophoretic forces can be performed more efficiently. In addition, damage to biomolecules can be prevented by lowering the intensity of a voltage for a dielectric electrophoresis phenomenon and the biosensor can be easily commercialized as a health care sensor for diagnosing diseases.

A miniature gas detection and purification device is disclosed for a user to carry with him, and includes a main body, a purification module, a gas guider and a gas detection module. The gas detection module detects the gas in the environment surrounding the user to obtain a gas detection datum, and controls the gas guider to be operated according to the gas detection datum, so that gas is inhaled into the main body and flows through the purification module for filtration and purification, and the gas purified is finally guided to an area nearby the user.

Provided is an electric dust collector comprising a dust collection unit that traps charged particles; and a microwave generation unit that generates a microwave to be introduced into the dust collection unit and combusts the charged particles trapped in the dust collection unit by the microwave.

Air filtration assemblies configured to provide instant detection of particles and/or improve particle filtration are disclosed. The assemblies may include an air inlet duct in fluid communication with a compressor of a gas turbine system. The air inlet duct may include an inlet for receiving intake air including intake air particles, and an outlet positioned opposite the inlet. The assembly may also include a plurality of vane filters at the inlet, an array of fabric filters positioned in the air inlet duct, downstream of the vane filters, and a silencer assembly positioned in the air inlet duct, downstream of the fabric filters. Additionally, the assembly may include an electrostatic component positioned in the air inlet duct, downstream of the fabric filters. The electrostatic component may be configured to charge the intake air particles that pass through the vane filters and the fabric filters.

Provided is a magnetic separator in which even when content of a magnetic sludge in a liquid to be treated increases, recovery performance of the magnetic sludge is less likely to degrade and a malfunction of the device is less likely to occur. Apart of an outer peripheral surface of a magnet drum is immersed in a flow of the liquid to be treated containing the magnetic sludge. A removing mechanism removes the magnetic sludge on the outer peripheral surface of the magnet drum from the outer peripheral surface of the magnet drum. A magnetic sludge containing information acquisition device acquires magnetic sludge containing information relating to a content of the magnetic sludge contained in the liquid to be treated. A control device changes a magnetic sludge removal capability of the magnet drum depending on the magnetic sludge containing information acquired by the magnetic sludge containing information acquisition device.

A ventilation system for a mobile structure, in particular a motor vehicle, includes: a variably adjustable filter device including at least one controllable, variable filter characteristic with regard to a pollutant class; means for collecting information about the air quality in the surroundings of the mobile structure and in particular information about the air quality in an interior of the mobile structure; and a control unit for varying filter characteristics of the filter device in a variable, in particular continuous, manner, on the basis of the information about the air quality.
