Background technology
In known technology, most scenes of fire adopt fire fighting truck to put out a fire to save life and property, and fire fighting truck uses in burning, dangerous place with a potential explosion operation conventionally, in its environment for use, be often more furnished with explosive imflammable gas, in field of employment, be also often stacked with flammable material. And how the fire fighting truck and the supporting engine thereof that use at present do not possess explosion-proof, flame proof function, especially engine exhaust emission system, the exhaust temperature of its discharge usually up to 600 DEG C～800 DEG C, and be mingled with ashes, Mars more, run into imflammable gas and material, be easy to cause fire, cause the expansion of the condition of a disaster and the increase of casualty loss. As a kind of blast pipe that Chinese patent CN200820192063.1 announces, comprise blast pipe, it is characterized in that: the outer surface at blast pipe adheres to layer oxide film. Above-mentioned blast pipe does not arrange cooling device, spark arrester and exhaust spark arrester, can not reduce Tail Pipe Temperature, the Mars in blast pipe can not be extinguished, and surface temperature is too high, therefore cannot use at some Petrochemical Places. This blast pipe plays a role to reducing exhaust pipe of engine temperature, but because the air pulse velocity variations of engine discharge is larger, particularly after gas strengthens, capacity increases, and the tail gas of discharge can not effectively be lowered the temperature in described fire extinguishing chamber, thereby the still excess Temperature of tail gas of discharging, and Mars to extinguish effect bad, still easily discharge from gas outlet, high can not the use in inflammable and explosive place of temperature of blast pipe, easily produce blast, cause security incident, cannot meet the requirement of fire fighting truck fire-extinguishing location disaster relief environment.
Summary of the invention
The object of this patent is to provide a kind ofly can be used safely in the exhaust cooling system of explosion risk environment and use the explosion-proof fire fighting truck of this exhaust cooling system.
A kind of exhaust cooling system, comprise blast pipe body, described blast pipe body is made up of exhaust manifold and blast pipe, described blast pipe has the inner and outer tubes of suit, and described inner tube is connected by bracing frame with outer tube, and the interlayer between inner tube and outer tube forms cooling jacket, water inlet pipe and outlet pipe are set on described outer tube, described water inlet pipe is connected with circulating pump, and described blast pipe arranges spark arrester, and described blast pipe body tip arranges spark arrester.
The all sides of described exhaust manifold arrange thermal insulation layer.
Described spark arrester is arranged on the middle part of blast pipe.
Described thermal insulation layer is heat-barrier material and sicker adhesive linkage.
Described water inlet pipe is positioned at blast pipe front end.
Described outlet pipe is positioned at blast pipe end.
A kind of explosion-proof fire fighting truck that uses above-mentioned exhaust cooling system, comprise chassis assembly, engine, cooling water tank and engine exhaust system, described engine exhaust system adopts above-mentioned exhaust cooling system, the water inlet end of described exhaust cooling system circulating pump and outlet pipe are communicated with described cooling water tank respectively, and described circulating pump is connected with the power circuit of described explosion-proof fire fighting truck by wire.
Exhaust cooling system of the present invention, blast pipe is set to the cooling water jacket structure being connected by inner and outer tubes suit, and by the circulating cooling water route of the circulating pump shape coupled engines last person of institute gas, thereby effectively reduce the temperature of blast pipe, avoided due to the too high adverse effect to flammable explosive gas in environment of Tail Pipe Temperature. Secondly, on blast pipe, being provided with spark arrester, is that engine gas is guided to the water surface, extinguish the most Mars of unburned by water after gas discharge, stop the outer row of ashes Mars in tail gas, eliminated the ignite hidden danger of flammable explosive gas and material in environment of Mars. Its three, applied heat-barrier material at the outer surface of exhaust manifold, the conduction of the high temperature that has completely cut off exhaust manifold to explosion risk environment. Reduce the temperature of high blast pipe body by above measure, make engine exhaust tube body and effluent air temp all be no more than 80 degrees Celsius. Explosion-proof fire fighting truck of the present invention is owing to being provided with exhaust cooling system of the present invention on engine, thereby met the requirement of explosion proof of fire fighting truck safe operation in explosion risk environment, can effectively avoid the generation of secondary disaster in fire-fighting operation process.
