    摘要: A cell culture incubator has a chamber divided into an incubation portion and a control portion. The incubation portion is adapted to contain a cell culture receptacle. A cell culture receptacle agitator is located in the control portion of the incubator and linkage between the cell culture receptacle agitator and the incubation portion of the chamber causes agitation of the cell culture receptacle. A heater in the control portion of the chamber heats air from the external environment and transports the heated air to the incubation portion of the chamber. A wall divides the chamber into the incubation portion and the control portion. The heater may be a forced air heater that provides a positive pressure to the incubation portion of the chamber to reduce contamination in the incubation portion. A nutrient and gas circulation system communicates with the cell culture receptacle in the incubation portion of the chamber. The nutrient and gas circulation system includes a gas source external to the incubation portion of the chamber and tubing provides communication between the gas source, the cell culture receptacle in the incubation portion of the chamber, and nutrient media. A filter in an opening of the incubation portion of the chamber communicates with the tubing to remove contaminants from gas emanating from the cell culture receptacle prior to venting to the external environment.

    摘要: A thermally integrated catalyst aftertreatment exhaust system includes a flow channel that directs diesel exhaust through a diesel oxidation catalyst unit that includes a diesel oxidation catalyst, by a doser that introduces DEF into the diesel exhaust, through a mixing chamber that includes a static metallic mixer coated with a DEF hydrolysis catalyst, and through an SCR unit that includes an SCR catalyst. The diesel oxidation catalyst converts a portion of diesel exhaust into water, carbon dioxide, or nitrogen dioxide. The DEF hydrolysis catalyst facilitates hydrolysis of the mixed DEF and diesel exhaust. The SCR catalyst facilitates reduction of NOx in the diesel exhaust. A first portion of the flow channel is in direct thermal contact with a second portion of the flow channel that houses the SCR unit such that heat from the diesel exhaust before the diesel exhaust reaches the doser is passed to the SCR unit.

    摘要: A mixing chamber can be used for treatment of diesel exhaust. The mixing chamber can include a mixing pipe that permits passage of diesel exhaust, an insertion pipe that inserts the diesel exhaust into the mixing pipe near the first end of the mixing pipe such that the diesel exhaust entering the mixing pipe has angular momentum with respect to a longitudinal axis of the mixing pipe, and a mixer that introduced gaseous ammonia into the diesel exhaust injected with the atomized diesel exhaust fluid (DEF). The mixing pipe can include a DEF doser that injects the atomized DEF into the diesel exhaust. The mixing pipe can have a larger cross section than the insertion pipe. The insertion pipe can insert the diesel exhaust into the mixing pipe before the location of the DEF doser.
