Exhaust pipe having cooling and fireproof functions and applied to dangerous goods transport vehicle

Abstract

The invention discloses an exhaust pipe having cooling and fireproof functions and applied to a dangerous goods transport vehicle. The exhaust pipe is characterized by comprising three parts including a tail gas pipe (1), a fireproof filter (2) and a fireproof cooler (4); the fireproof filter (2) is arranged inside the tail gas pipe (1); and the tail gas pipe (1) is arranged in an internal cavity of the fireproof cooler (4). The exhaust pipe is simple in structure and good in working stability and can be widely applied on the dangerous goods transport vehicle, and the theory is easy to understand.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust pipes, in particular to an exhaust pipe technology for a dangerous goods transport vehicle with the function of cooling and preventing fire. Background technique [0002] The dangerous goods transport vehicle is a special-purpose vehicle with a front exhaust pipe and a spark-proof device for transporting petrochemicals, firecrackers, explosives and other flammable and explosive goods. According to statistics, more than 95% of dangerous goods in my country involve transportation problems such as remote locations, long distances, and large tonnages. Taking liquid ammonia as an example, its annual flow volume reaches more than 900,000 tons, and the annual flow volume of liquid chlorine reaches more than 1.8 million. tons, 80% of which is transported by road. The transportation of hazardous chemicals seems to be a simple process of object transfer, but due to the special nature of the goods...
