摘要:
The invention relates to a device (1) for providing a gaseous mixture comprising at least one of the following substances: a) at least one reducing agent and b) at least one reducing agent precursor. A reservoir (20) for the aqueous solution (45) comprises at least one reducing agent precursor that can be fluidically connected to an evaporator chamber (24), and means for dosing the aqueous solution (45) in the evaporator chamber (24). Means (27, 63) for heating the evaporator chamber (24), which can heat the evaporator chamber (24) to a temperature higher than or equal to a critical temperature, in which the aqueous solution (45) is at least partially evaporated, are provided. The device according to the invention (1) and the inventive method enable a reducing agent to be provided for selective catalytic reduction of nitrogen oxides in the waste gas of an internal combustion engine. In a preferred embodiment, the evaporator unit (12) is configured as an evaporator chamber (24) and the hydrolysis catalyst (17) is arranged outside the waste gas system. As a result, the size of the hydrolysis catalyst (17) is reduced, allowing a compact design.
摘要(中):
本发明涉及一种用于提供包含以下物质中的至少一种的气体混合物的装置(1):a)至少一种还原剂和b)至少一种还原剂前体。 用于水溶液(45)的储存器(20)包括至少一种能够流体连接到蒸发器室(24)的还原剂前体,以及用于将蒸发室(24)中的水溶液(45)计量的装置。 用于加热蒸发器室(24)的装置(27,63),其可将蒸发器室(24)加热到高于或等于临界温度的温度,其中水溶液(45)至少部分蒸发, 被提供。 根据本发明(1)的装置和本发明的方法使得能够提供还原剂用于内燃机的废气中的氮氧化物的选择性催化还原。 在优选实施例中,蒸发器单元(12)构造为蒸发器室(24),并且水解催化剂(17)布置在废气系统的外部。 结果,水解催化剂(17)的尺寸减小,从而使设计紧凑。
