The present invention provides an air purifier. The air purifier is economical and reliable. The air purifier uses water to purify air. The air purifier provides a provision for killing bacteria, algae and prevents mosquitoes from breeding in the water of the air purifier. The purifier includes a housing, an air inlet, an air outlet, an air flow channel, an air driving means and an air exhaust means, a fluid reservoir, a heating module, at least one nozzle, a tray and a fluid drive means. More particularly, in the present invention an atmospheric air is sucked into the air flow channel by the air driving means, wherein the air stream passes under a fluid spray, whereupon a dust particles, pollutants and particulate matters are absorbed by the fluid coming in contact with it and the filtered air exits through the air outlet.

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

A robot according to an embodiment of the present invention comprises: at least one wheel for traveling; a water tank in which an accommodating space accommodating water is formed; a water pump connected to the water tank; a water purifier connected to the water pump to purify and discharge water provided from the water tank; and an air cleaner configured to suction and filter air and discharge the filtered air, wherein the water tank is disposed below the water pump, the water purifier, and the air cleaner.

The present invention discloses an apparatus (100), for scrubbing smoke comprising: a first tank (110), having a compartment (111), filled with a liquid; and, an inlet (112), configured to draw in the smoke into the compartment (111) from a combustion source, characterized in that, the first tank (110) includes a propeller system (113), arranged within the compartment (111) to mix the smoke with the liquid, for providing first scrubbing effect by propelling the liquid.

A scrubber for treating exhaust gas generated by combustion of biomass comprises a plurality of chambers each configured to apply a scrubbing medium to the exhaust gas for removing solid particles from the exhaust gas. A first chamber includes at least one nozzle configured to dispense scrubbing liquid in a sheet oriented transversely to a path of flow of exhaust through the first chamber. A second chamber defines a reservoir for containing a bath of scrubbing liquid and further includes a baffle configured to deflect the exhaust gas into the bath. A third chamber is arranged to support a sheet of solid filter medium spanning across the chamber.

A portable air filtration and disinfection device for a respirator system includes a casing, an inhalation filter assembly, and an exhalation filter assembly. The inhalation filter assembly includes an intake duct for receiving breathing air, an inhalation gas filter for filtering the breathing air, and an inhalation duct to provide the filtered breathing air. The exhalation filter assembly includes an exhalation duct for receiving exhaled air, an exhalation gas filter and an exhalation liquid filter for filtering and disinfecting the exhaled air, and an outlet duct for releasing the filtered and disinfected exhaled air.

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.

Thermal treatment techniques for recycling are generally very clean but their byproducts include a fine ash that may become entrained in the exhaust air plume as smoke. We therefore disclose a materials recycling apparatus comprising a heat treatment chamber for processing the material at an elevated temperature, the chamber having a vent leading via a heat exchanger to a scrubber comprising a disrupted flow path, at least one spray nozzle directed towards the disrupted flow path, and a supply of liquid (ideally water with a little detergent) to the or each spray nozzle. In this way, the entrained ash can be efficiently removed from the air flow, allowing it to be vented, and the captured ash disposed of via a waste water outlet together with the ash washed from the chamber. The flow path can be disrupted by at least one baffle plate, ideally with the spray nozzle located ahead of the baffle plate(s).
