In order to provide a dust-containing gas treatment apparatus which can smoothly achieve the treatment of gas containing dust of high concentration, the apparatus is equipped with a cylindrical treatment room to introduce gas containing dust and remove the dust from the gas, catcher consisting of brush with the hair planted in the support installed in the treatment room to catch the dust contained in the gas, liquid spraying mechanism installed in the treatment room, rotary driving mechanism to rotate the catcher and stirrer, gas introducing portion to introduce the gas containing dust, gas discharging portion to discharge the gas, the dust removed, from the treatment room and liquid discharging portion to discharge the liquid containing the dust removed from the gas.

Disclosed are a pollutant capturer and mobilizer and method of mobilizing a polluted gaseous substance from one location towards another location and capturing one or multiple types of polluting substances, such as CO.sub.2, from an atmospheric body of polluted gaseous substance or from exhaust of vehicles, chimneys, or stacks and thereby combat the negative health, environmental, and economic impacts of the of the polluting substances on communities. Wet or dry embodiments of the pollutant capturer and mobilizer utilize wet or dry pollutant capturing components, respectively, to capture one or multiple types of polluting substances from a body of polluted gaseous substance. Flow establishing devices can be used to set the body of polluted gaseous substance in motion through the pollutant capturing component. The pollutant capturer and mobilizer may also be mounted on any type of vehicles, with or without using flow establishing devices.

A ventilation type air cleaner includes a housing having a central rotating shaft including a purification part, a washing part, and a sterilization part in a circumferential direction with respect to the central rotating shaft, a rotating unit installed to be rotatable about the central rotating shaft as a rotation center in the housing, a filter assembly detachably coupled to the rotating unit and configured to sequentially pass through the purification part, the washing part, and the sterilization part according to rotation of the rotating unit, an intake duct connected to the housing and configured to guide a flow of air introduced to the purification part, and an exhaust duct connected to the housing and configured to guide a flow of air discharged from the purification part.

Apparatus and methods are disclosed. The apparatus comprises: an abatement chamber of an abatement apparatus which treats an effluent stream from a semiconductor processing tool to provide a combusted effluent stream having effluent particles; and a first atomiser located downstream of the abatement chamber, the first atomiser being configured to produce droplets having a droplet size based on a particle size of the effluent particles to be removed from the combusted effluent stream. In this way, the atomizer may produce droplets which combine with or adhere to the effluent particles which assists in the removal of the effluent particles from the combusted effluent stream.

An autothermal direct air capture system (ADAC) is disclosed. The ADAC includes a chamber, a water reservoir, and a sorbent that releases water under ambient conditions, binds water under a first moisture level higher than the ambient moisture level, binds CO.sub.2 under ambient conditions, and releases CO.sub.2 under at least one of an elevated temperature and the first moisture level. The ADAC is movable between a capture configuration and a regeneration configuration, the capture configuration including the sorbent being exposed to a gas volume having CO.sub.2 under ambient conditions, the sorbent binding with CO.sub.2 while desorbing water, the sorbent selected so the sorbent material extracts heat while the ADAC is in the capture configuration, resulting in the thermal charging of the sorbent. The regeneration configuration includes the sorbent inside the chamber and in contact with water, the sorbent releasing carbon dioxide while binding water and depositing heat into the chamber.

An apparatus for trapping an exhaust material from a substrate-processing process includes: a cyclone configured to provide the exhaust material with a swirling flow, wherein the exhaust material is discharged from the substrate-processing process using a reaction gas; an atomization module for providing the cyclone with a mist to convert the exhaust material into a powder through a wet oxidation reaction, and a collector configured to collect the powder.

A wet scrubber at least comprises a treatment tank, a jet pipe, a gas-liquid separation component, and a spray component. The treatment tank is used to contain a cleaning solution. The jet pipe is disposed in the treatment tank, by injecting the cleaning solution to suck in an exhaust gas, and mixing the cleaning solution with the exhaust gas, and directly injecting into the cleaning solution contained in the treatment tank, thereby forming a plurality of microbubbles in the cleaning solution to dissolve the exhaust gas and capture solid particles in the exhaust gas. The gas-liquid separation component is used to filter and block water mist raised in the cleaning solution. The spray component is used to prevent the solid particles from clogging the gas-liquid separation component.
