摘要:
A reducing agent aqueous solution mixing device includes an exhaust pipe, an injector, a mixing pipe and an inner pipe. The exhaust pipe includes an elbow part having a curved portion, and a linear part disposed downstream of the elbow part. The injector is disposed outside the curved portion and injects the reducing agent aqueous solution towards the linear part. The mixing pipe is disposed inside the elbow part to surround the reducing agent aqueous solution injected from the injector. The mixing pipe includes a plurality of openings on its outer peripheral surface. The inner pipe is disposed downstream of the mixing pipe and spaced apart from an outlet portion of the mixing pipe and from an inner wall of the linear part to allow the exhaust gas to flow through the inside of the inner pipe and along the outer periphery of the inner pipe.

A reducing agent aqueous solution mixing device includes an exhaust pipe, an injector, an inner pipe and a tubular guide member. The exhaust pipe includes an elbow part having a curved portion, and a linear part disposed downstream of the elbow part. The injector is disposed outside of the curved portion, and injects a reducing agent aqueous solution into the elbow part towards the linear part. The inner pipe is disposed downstream of the injector within the exhaust pipe. The inner pipe has an inlet portion opening facing the injector and an outer peripheral surface spaced apart from the inner wall of the linear part. The inner pipe allows the exhaust gas to flow through the inside of the inner pipe and along the outer periphery of the inner pipe. The tubular guide member directs the reducing agent aqueous solution injected from the injector to the inner pipe.

A reducing agent aqueous solution mixing device includes an exhaust pipe, an injector, an inner pipe and a tubular guide member. The exhaust pipe includes an elbow part having a curved portion, and a linear part disposed on a downstream side of the elbow part. The injector is disposed outside the curved portion and injects only a reducing agent aqueous solution into the elbow part towards the linear part. The inner pipe is disposed on an exhaust stream downstream side of the injector within the exhaust pipe with an inlet portion opening thereof facing the injector and an outer peripheral surface thereof being spaced apart from the inner wail of the linear art. The inner pipe allows the exhaust as to flow through the inside thereof and the outer periphery thereof. A tubular guide member directs the reducing agent aqueous solution injected from the injector to the inner pipe.
摘要:
An apparatus for efficiently cooling the heat of a hot target without enlarging the size of a cooling device or needing either a piping to connect an evaporation portion and a condensation portion or a steam circulation pump. An exoergic-side heat exchanger has a fluid passage for the target fluid, and stores a coolant for cooling the fluid in the fluid passage through heat exchange. An endoergic-side heat exchanger has at least two coolant passages, the one ends of which communicate with the endoergic-side heat exchanger, and the other ends of which communicate with each other through a common coolant passage. A cooling device cools the coolant by exchanging heat with the coolant passing through the exoergic-side heat exchanger. The coolant passage has a diameter or an equivalent diameter within a range of 2 mm to 16 mm, and all the coolant passages have a substantially identical or equivalent diameter.
