摘要:
A regenerative selective catalytic reduction process includes providing a gas stream to be treated containing NOX, introducing a reactant into the gas stream, and directing the gas stream into contact with a catalyst to cause at least some of the NOX contained in the gas stream to be reduced, wherein the gas stream is adapted to flow past the catalyst along the same flow direction throughout the process in a substantially continuous manner. The process also includes heating the gas stream with a heater upstream of the catalyst to provide supplemental heat to the gas stream from a first heat exchanger during a first cycle, and to provide supplemental heat to the gas stream from a second heat exchanger using the same heater during a second cycle.

To provide a solvent separator for purifying an exhaust atmosphere efficiently in solvent removal from the exhaust atmosphere containing a vaporized solvent by the heating exhausted from an exhaust generator, so that the vaporized solvent does not slip through an electrode for collecting the solvent and is positively led to the electrode. An electrode is arranged in a first wall surface of a casing of a solvent separation unit having a circular cylindrical shape, thereby inducing a vaporized solvent in an exhaust atmosphere to the electrode by a fan and discharging the solvent to the outside of the separator with part of the peripheral exhaust atmosphere while attracting the solvent to the electrode by an electric field of the electrode.

An air purification system for purifying polluted air includes a scrubber in which a pollutant in the polluted air is transferred to a scrubber liquid. A biological treatment unit includes at least one substantially flat substrate to support a microorganism population to remove the transferred pollutant from the scrubber liquid when the scrubber liquid with the transferred pollutant is distributed on the substrate. A plane of the substrate is substantially parallel to a direction of flow of the air from the scrubber.

The fuel tank cap with a separated charcoal canister includes a fuel tank cap, a charcoal cap, and a fuel tank outer cap. A filling room is disposed on the charcoal cap, and the upper opening of the filling room is covered by the fuel tank outer cap. The fuel tank cap with a slot is disposed under of the charcoal cap. The fuel tank can be connected in detachable way with either the charcoal cap or fuel tank outer cap. A through orifice is disposed in the center of the fuel tank cap. The through orifice and the filling room filled by fuel-absorption substrate are connected by the first passageway disposed on the charcoal cap. The charcoal canister is a standard product, and it can fit to variable fuel tanks through the variable sized fuel tank cap, thereby both design and manufacturing processes are simplified and costs are saved.

Embodiments of the present disclosure include methods and systems of circulating air in an enclosed environment. In such embodiments, the system may comprise an air handling unit (AHU), the AHU including an indoor air inlet to receive an indoor airflow from the enclosed environment and an indoor air outlet to expel the indoor airflow, a conditioning element arranged between the inlet and the outlet configured to at least heat or cool the indoor airflow as it flows thereover, one or more fan units arranged between the inlet and the outlet configured to provide velocity to the indoor airflow, and an air treatment assembly (ATA) arranged within or proximate the AHU, the ATA including an air inlet configured to receive a portion of the indoor airflow received by the AHU indoor air inlet.
摘要:
An absorption-type carbon dioxide removal/condensing apparatus is removes or condenses carbon dioxide so that the apparatus secures high recovery efficiency. The apparatus has a honeycomb rotor holding a carbon dioxide absorbent, which is divided into at least a processing zone and a reproduction zone. After anyone of reproduction air for heating and a processing air is humidified by a humidifying device, both airs are ventilated into the zones, respectively. Thereby, the apparatus can improve absorption performance and density performance. If the honeycomb rotor is further divided into at least first and second processing zones, an air to be processed is humidified by a humidifier to ventilate into the first processing zone, and then a portion or all of the processing air which passed through the first procession zone is passed through the second procession zone (second pass).
摘要:
Disclosed is an HVAC system having one or more air ionization devices for increasing operating efficiency and reduces overall cost by reducing the level of volatile organic compounds in recirculated building air. Also disclosed are combinations of heat exchangers operating in conjunction with ionization to further reduce operating costs. Included are various control sequences for a controller useful for managing air quality using CO2, VOC and other sensors to maintain air quality at reduced cost.
