A air curtain for urea mixing chamber

The utility model relates to an air curtain for urea mixing chamber. The embodiment of example includes mixing chamber, and mixing chamber has urea entry, mixing chamber gas access and mixing chamber export. The urea source provides pressor urea solution to urea with urea injection pressure and enters the mouth to pressor gas source will be pressurizeed gas via the route and conveyed to the mixing chamber gas access. The route is configured as with the gaseous pressure of the pressurization along the conveying of its length from the first pressure decrease of the gas of receiving the self -pressurization gas source to providing to the second pressure of the gas of mixing chamber gas access. The first pressure of receiving the gas of self -pressurization gas source is greater than urea injection pressure to a second pressure is less than urea injection pressure that to the gas of mixing chamber gas access is provided. 本实用新型涉及用于尿素混合室的空气帘。示例性的实施方案包括掺混室，掺混室具有尿素入口、掺混室气体入口和掺混室出口。尿素源以尿素注入压力将加压的尿素溶液提供至尿素入口，并且加压的气体源经由
