Exhaust pipe realizing fire prevention through cooling, for hazardous material transportation vehicle

Abstract

The invention discloses an exhaust pipe realizing fire prevention through cooling, for a hazardous material transportation vehicle. A fireproof cap is arranged at the rear end of a tail gas pipe (1). The exhaust pipe is characterized by comprising two parts, that is, the tail gas pipe (1) and a fireproof cooler (4), wherein the tail gas pipe (1) is arranged in the inner cavity of the fireproof cooler (4); and the fireproof cooler (4) is arranged outside the tail gas pipe (1), a cooling liquid inlet (41) is formed above the left end of the fireproof cooler (4), a cooling liquid outlet (42) is formed above the right end of the fireproof cooler (4), the cooling liquid inlet (41) communicates with the cooling liquid outlet (42) through a cooling liquid channel (43), and the cooling liquid channel (43) is in the shape of a spiral line. The exhaust pipe disclosed by the invention is simple in structure, easily understandable in principle, high in working stability, and capable of being widely applied to hazardous material transportation vehicles.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust pipes, in particular to an exhaust pipe technology of 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,...

Problems solved by technology

Although it can solve some problems to a certain extent, the falling off of the fire cap also poses a safety hazard. At the same time, it is difficult to completely eliminate the sparks mixed in the exhaust only through the fire cap.
