Description

Smoke exhaust connecting structure for fire extinguishing star muffler

Technical Field

The utility model relates to a diesel engine technical field specifically is a star muffler of putting out a fire is with connection structure that discharges fume.

Background

The diesel engine is an engine which burns diesel to obtain energy release, and has the advantages of large torque and good economic performance. The working process of a diesel engine is much the same as that of a gasoline engine, and each working cycle also goes through four strokes of intake, compression, power and exhaust. However, the fuel for diesel engine is diesel oil, which has higher viscosity than gasoline and is not easy to evaporate, and its self-ignition temperature is lower than gasoline, so the formation and ignition mode of combustible mixture are different from that of gasoline engine. The difference is mainly that the mixture in the cylinder of the diesel engine is compression ignited, not ignited. When the diesel engine works, air enters the cylinder, and when the air in the cylinder is compressed to the end point, the temperature can reach 500-700 ℃, and the pressure can reach 40-50 atmospheric pressures. When the piston is close to the top dead center, the fuel nozzle of the fuel supply system sprays fuel to the combustion chamber of the cylinder in a very short time at a very high pressure, the diesel oil forms fine oil particles, the fine oil particles are mixed with high-pressure and high-temperature air, the combustible mixed gas is combusted by itself and expands violently to generate explosive force to push the piston to do work downwards, the temperature can reach 1900-2000 ℃, the pressure can reach 60-100 atmospheric pressures, and the generated torque is very large, so that the diesel engine is widely applied to large-scale diesel equipment.

On the current diesel engine, in order to prevent to produce the spark in the blast pipe, produce great noise, prevent simultaneously that the diesel oil in spark and the air from mixing and causing the incident emergence, often need the installation star silencer of putting out a fire, current star silencer of putting out a fire is when using, often can be disturbed by external environment, if can cause outside water to enter into the silencer, cause the damage to the silencer, and current silencer is connected with the blast pipe, directly be connected with the blast pipe with the weight of whole pipeline, the bearing capacity of blast pipe has been increased, the life of blast pipe has been reduced.
