Exhausting spark prevention device of internal combustion locomotive

Abstract

The invention discloses an exhausting spark prevention device of an internal combustion locomotive, and solves the problems in the prior art that when exhaust gases of the internal combustion locomotive are treated, water in a water tank easily evaporates or the centrifugal separation effect of particles with sparks is poor. The exhausting spark prevention device comprises an exhaust box, whereinan exhaust pipe is arranged in an exhaust pipe installing hole of the center of the bottom of the exhaust box; the bottom end of the exhaust pipe is connected to an exhaust port of a supercharger of the internal combustion locomotive; a protecting net is arranged at an opening of the top of the exhaust box and comprises a protecting net support; an exhaust net is arranged on the top surface of theprotecting net support; a rain shield plate which directly faces a top opening of the exhaust pipe is arranged at the center of the exhaust net; a V-shaped flow guide plate is arranged at the bottomof the rain shield plate; the two sides of the V-shaped flow guide plate and the two corresponding inner side walls of the exhaust tank respectively form two exhaust channels; and two sliding chutes which are distributed at intervals in parallel are arranged at each side of the V-shaped flow guide plate; and a spark prevention net is arranged in each sliding chute. The exhausting spark preventiondevice can effectively intercept high-temperature residual oil with sparks and carbon granules in the exhaust gases, and has a noise reduction effect.

Description

technical field [0001] The invention belongs to the field of exhaust systems of diesel locomotives, and in particular relates to an anti-spark device for exhaust of diesel locomotives. Background technique [0002] At present, the explosion-proof technologies used in diesel engine exhaust systems used in places with explosion-proof requirements can be roughly divided into three categories: 1) intercept high-temperature residual oil and carbon particles with sparks in the exhaust gas through multi-mesh materials; Pour into water to cool and filter before discharging; 3) Separate particles with a density greater than gas by centrifugal force. The above technologies are mostly applied to fixed diesel engines or construction machinery. If water-cooled filtration is used for high-power diesel locomotives, due to the high exhaust temperature and large exhaust volume, the water in the water tank will be evaporated quickly; The density of particles with Mars is very small, the cent...
