Background technique
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 usually, often more is furnished with explosive inflammable gas in its Environmental Conditions, also often is stacked with flammable material in the field of employment.And how the fire-fighting truck and the supporting motor 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 ℃～800 ℃, and be mingled with ashes, Mars more, run into inflammable gas and material, be easy to cause fire, cause the expansion of the condition of a disaster and the increase of casualty loss.A kind of outlet pipe as Chinese patent CN200820192063.1 announces comprises outlet pipe, and it is characterized in that: the outer surface at outlet pipe adheres to layer oxide film.Above-mentioned outlet pipe does not arrange cooling unit, spark arrester and exhaust flame trap, can not reduce Tail Pipe Temperature, can not the Mars in the outlet pipe be extinguished, and surface temperature is too high, therefore can't use at some Petrochemical Places.This outlet pipe plays a role to reducing the engine exhaust pipe temperature, but because the pulsing airflow velocity variations of engine emission is larger, particularly after gas strengthens, air displacement increases, and the tail gas of discharging can not effectively be lowered the temperature in described fire extinguishing chamber, thereby the tail gas of discharging excess Temperature still, and Mars to extinguish effect bad, still easily discharge from the air outlet, the temperature height of outlet pipe can not use in inflammable and explosive place, produce easily blast, cause security incident, can't satisfy the requirement of fire-fighting truck fire-extinguishing location disaster relief environment.
Summary of the invention
The purpose of this patent provides 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 the outlet pipe body, described outlet pipe body is comprised of gas exhaust manifold and outlet pipe, described outlet pipe has the inner and outer tubes of suit, and described inner tube is connected by supporting frame with outer tube, and the interlayer between inner tube and the outer tube consists of cooling jacket, intake pipe and outlet pipe are set on the described outer tube, described intake pipe is connected with recycle pump, and described outlet pipe arranges spark arrester, and described outlet pipe body tip arranges flame trap.
The all sides of described gas exhaust manifold arrange thermal-protective coating.
Described spark arrester is arranged on the middle part of outlet pipe.
Described thermal-protective coating is thermal-protective material and sicker adhesive layer.
Described intake pipe is positioned at the outlet pipe front end.
Described outlet pipe is positioned at the outlet pipe end.
A kind of explosion-proof fire-fighting truck that uses above-mentioned exhaust cooling system, comprise chassis assembly, motor, cooling water tank and engine exhaust system, described engine exhaust system adopts above-mentioned exhaust cooling system, the feed-water end of described exhaust cooling system recycle pump and outlet pipe are communicated with described cooling water tank respectively, and described recycle pump is connected with the power circuit of described explosion-proof fire-fighting truck by wire.
Exhaust cooling system of the present invention, outlet pipe is set to the cooling water jacket structure by the connection of inner and outer tubes suit, and form circulating cooling water route to the motor last person of institute gas by recycle pump, thereby effectively reduced the temperature of outlet pipe, avoided because the too high adverse effect to flammable explosive gas in the environment of Tail Pipe Temperature.Secondly, being provided with spark arrester at outlet pipe, is that engine gas is guided to the water surface, extinguishes behind the most Mars of unburned gas by water and discharges, stop effluxing of ashes Mars in the tail gas, eliminated the ignite hidden danger of flammable explosive gas and material in the environment of Mars.Its three, applied thermal-protective material at the outer surface of gas exhaust manifold, completely cut off the high temperature of gas exhaust manifold to the conduction of explosion risk environment.Reduce the temperature of high outlet pipe body by above measure, make engine exhaust tube body and effluent air temp all be no more than 80 degrees centigrade.Explosion-proof fire-fighting truck of the present invention is owing to be provided with exhaust cooling system of the present invention at motor, thereby satisfied the requirement of explosion proof of fire-fighting truck safe operation in the explosion risk environment, can effectively avoid the generation of secondary disaster in the fire-fighting operation process.
