Abstract
A reducing agent aqueous solution mixing device includes an exhaust pipe, an injector, a mixing pipe, an inner pipe and a flow section. The exhaust pipe includes an elbow part and a linear part. The injector is disposed in the elbow part and injects a reducing agent aqueous solution. The mixing pipe receives the reducing agent aqueous solution injected from the injector, and includes an outlet portion formed spaced apart from an inner wall of the exhaust pipe, and a plurality of openings formed on the outer peripheral surface thereof. The inner pipe is disposed in the linear part and allows the exhaust gas to flow through the inside and the outer periphery thereof. The flow section is formed between the outlet portion of the mixing pipe and the inner wall of the exhaust pipe to direct the exhaust gas to the inner pipe.
