Description
Technical field
The present invention relates to automobile exhaust pipe technical field, more particularly to a kind of hazardous materials transportation by the fire-proof function that cools
Vehicle exhaust pipe technology.
Background technology
Hazardous materials transportation car be a kind of blast pipe it is preposition and equipped with spark preventer, transport petrochemical praduct, firecrackers, explosive
Deng the special purpose vehicle of inflammable explosive article.According to statistics, the dangerous material of China more than 95% are related to the transport such as strange land, long-distance, large-tonnage and asked
Topic, by taking liquefied ammonia as an example, its year amount of flow is up to more than 90 ten thousand tons, and the year amount of flow of liquid chlorine is even more to have reached more than 180 ten thousand tons, wherein passing through
Account for total amount the 80% of road transport completion.Harmful influence transport seems a simple object transfer process, but due to goods tool
Have specific characteristics, once occurring unexpected, what may be triggered is exactly extent of injury height, the peace of pollution range extensively such as explode, reveal, pollute
Full accident.
In the main cause that hazardous materials transportation car explodes, just have because vehicle itself somewhere is overheated or is produced because rubbing
Caused by spark.In the course of the work, the tail gas discharged in blast pipe is often mingled with some Mars or spark to fuel engines,
This is the maximum hidden danger of hazardous materials transportation vehicle inherently safe.The Mars solved in this bad problem, tail gas from exhaust pipe will
As the time bomb for causing car accident.The many flash hiders on blast pipe tail end set of current hazardous materials transportation car.Though
So some problems can be solved to a certain extent, but coming off for flash hider equally exists potential safety hazard, while only difficult by flash hider
To prevent the Mars being mingled with tail gas completely.
The content of the invention
The main technical problem to be solved in the present invention is：There is provided a kind of understandable principle, compact conformation, good operating stability,
With the high life by the fireproof hazardous materials transportation vehicle exhaust pipe that cools, to eliminate in the fuel engines course of work, only make
The problem of being difficult to prevent the Mars being mingled with tail gas completely with flash hider, so as to improve hazardous materials transportation car self-security.
The technical scheme is that：One kind is by the fireproof hazardous materials transportation vehicle exhaust pipe that cools, and offgas duct rear end is set
It is equipped with flash hider, including offgas duct and fire prevention cooler two large divisions；Offgas duct is placed in the internal cavities of fire prevention cooler；Institute
State fire prevention cooler to be placed in outside the offgas duct, cooling liquid inlet is provided with above the fire prevention cooler left end, on right-hand member
Side is provided with cooling liquid outlet, and cooling liquid inlet is connected with cooling liquid outlet by cooling passage, and the cooling passage is in
Spiral line type.
Stable bail is provided with outside the fire prevention cooler, the stable bail quantity is more than 2, and upper end
It is designed with stability thread hole.
Described cooling liquid inlet and the quantity of cooling liquid outlet are more than 1.
The beneficial effects of the invention are as follows：The invention employs fire prevention cooler and fire prevention filter, and both of which, which has, to disappear
Except the Mars or the function of spark carried secretly in tail gas, it can ensure that in the tail gas finally ejected and will be free from Mars, so as to protect
Card transport vehicle will not trigger security incident because of the Mars carried secretly in tail gas.
The function of fire prevention cooler and flash hider is as follows：Cooling passage is designed with cooler, is cooled down during work
Liquid flows in the channel.Because offgas duct is in inside cooler, such that the temperature drop of offgas duct, so as to realize
Cooling-down effect；This same offgas duct that can also to be in below cooler is constantly in the state of low temperature, when tail gas is by dropping
During warm device section, exhaust temperature can drastically decline.If containing Mars in tail gas now, then Mars can because temperature drastically under
Drop and extinguish.If the Mars in tail gas does not extinguish also by cooler section, then the flash hider at cooler rear is then acted as
With Mars can also extinguish in flash hider.Cooler and flame damper are used in combination, and cleverly arrange in pairs or groups so that blast pipe equivalent to
With two grades of fire-proof functions, service behaviour is protected, so as to ensure that the tail gas got into the air will not be mingled with Mars, thus protects
Card hazardous materials transportation car will not carrying Mars and causing security incident in or tail gas too high because of Tail Pipe Temperature.

Embodiment
Refering to accompanying drawing 1-3, a kind of hazardous materials transportation vehicle exhaust pipe with cooling fire-proof function, including offgas duct 1 and anti-
The fiery two large divisions of cooler 4；Offgas duct 1 is placed in the internal cavities of fire prevention cooler 4；The fire prevention cooler 4 is placed in described
Outside offgas duct 1, cooling liquid inlet 41, right-hand member top are provided with above the fire prevention left end of cooler 4 and is provided with coolant and goes out
Mouthfuls 42, cooling liquid inlet 41 is connected with cooling liquid outlet 42 by cooling passage 43, the cooling passage 43 helically line
Type；Stable bail 44 is provided with outside the fire prevention cooler 4, the stable quantity of bail 44 is more than 2, and upper end
It is designed with stability thread hole；Described cooling liquid inlet 41 and the quantity of cooling liquid outlet 42 are more than 1.
The invention employs fire prevention cooler to aid in flash hider, both of which have eliminate the Mars carried secretly in tail gas or
The function of spark, can ensure that in the tail gas finally ejected and will be free from Mars, so as to ensure the security of transport vehicle.And drop
Temperature, fire prevention are an entirety, are not in a series of problem as additional flash hider on automobile blast pipe itself.
The invention main operational principle and process are as follows：Due to being designed with cooling passage in cooler, cooled down during work
Liquid flows in the channel, so that environment temperature is very low.Again because offgas duct is inside cooler, such that tail
The temperature drop of tracheae, so as to realize cooling-down effect；Same this can also cause the offgas duct below cooler to be constantly in
The state of low temperature.When tail gas is by cooler section, exhaust temperature can drastically decline, if containing Mars in tail gas now,
So Mars can extinguish because of sharp temperature drop, and at least small Mars of this process has extinguished.If the Mars warp in tail gas
Cross cooler section not extinguish also, then the flash hider at cooler rear then works, and Mars passes through in the presence of flash hider, fire
Star can also extinguish in flash hider.Cooler and flame damper are used in combination, and cleverly arrange in pairs or groups so that blast pipe is equivalent to two
Level fire-proof function, service behaviour is protected, so as to ensure that the tail gas got into the air will not be mingled with Mars, hereby it is ensured that dangerous
Product transport vehicle will not carrying Mars and causing security incident in or tail gas too high because of Tail Pipe Temperature.
Described above is the present invention preferably example, does not make scope limitation to the present invention, all according to the technology of the present invention side
The substantive of case makees simple change and improvement etc., belongs to the patent protection category of the present invention.
