Description
Technical field
The present invention relates to automobile exhaust pipe technical field, more particularly to a kind of hazardous materials transportation car row with fire-proof function
Tracheae 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, and the replacement cycle is also individual
Problem.
The content of the invention
The main technical problem to be solved in the present invention is：Invent a kind of understandable principle, compact conformation, good operating stability,
With the high life, the hazardous materials transportation vehicle exhaust pipe of anti-Mars, to eliminate in the fuel engines course of work, blast pipe can be realized
Some Mars or spark that tail gas is mingled with, while solving the problem of flash hider comes off.So as to improve hazardous materials transportation car itself
Security.
The technical scheme is that：A kind of hazardous materials transportation vehicle exhaust pipe with fire-proof function, including it is offgas duct, anti-
Fiery filter two large divisions；Fire prevention filter is placed in the inside of offgas duct；Halfpace is provided with inside the offgas duct right-hand member, it is described anti-
Fiery filter is placed in offgas duct, halfpace of the left end in offgas duct, sets flexible in the middle of halfpace with fire prevention filter
Packing ring.
The fire prevention filter is made up of preceding fire prevention screen pack and rear fire prevention screen pack.
Described fire prevention filter right-hand member is provided with protective cover, and cushion is provided with the middle of protective cover with fire prevention filter
Circle.
Fire prevention screen pack is in spider reticulation type before described, and the rear fire prevention screen pack is in mesh-like, fine by wire, asbestos
Dimension or glass fibre are made.
Distance is 20mm-50mm between preceding fire prevention screen pack and rear fire prevention screen pack.
The aperture of the protective cover is identical with fire prevention filter, and in circular hole.
The beneficial effects of the invention are as follows：The invention employs fire prevention filter, is respectively provided with the Mars for eliminating and being carried secretly in tail gas
Or the function of spark, it can ensure that in the tail gas finally ejected and will be free from Mars, so as to ensure that transport vehicle will not be because of tail gas
The Mars of middle entrainment triggers security incident.Preceding fire prevention screen pack is in spider reticulation type, and rear fire prevention screen pack is in mesh-like why
The front and rear filtering mesh-shaped of design is different, in order that increase fire protection efficiency.It is to first pass through preceding net when tail gas flows through fire prevention filter,
By net later.Mars is small particulate matter, but the small particle thing such as Mars is focused more in pipe in tail gas discharging pipe
The heart and following position.Preceding net is designed to spider reticulation type, then center to the twine density of tube wall can so be had by intensive to sparse
Beneficial to the fire protection efficiency for improving screen pack, while also will not be because twine density is excessive and influences the emission performance of tail gas.
The function of fire prevention filter is as follows：If containing Mars in tail gas, it is entered when it is by fire prevention screen pack
Row filtering, Mars extinguishes in fire prevention filter.Service behaviour is protected, so as to ensure that the tail gas got into the air will not be pressed from both sides
Miscellaneous Mars, hereby it is ensured that hazardous materials transportation car will not carrying Mars and causing safe thing in or tail gas too high because of Tail Pipe Temperature
Therefore.
Brief description of the drawings

Fig. 2：For the preceding fire prevention screen pack side view of the present invention；
Fig. 3：For the rear fire prevention screen pack side view of the present invention
Fig. 4：For the fire prevention filter protective cover side view of the present invention.
In figure：Prevent fires and filter before 1- offgas ducts, 11- inlet exhaust gas end, 12- offgas outlets end, 2- fire prevention filters, 21-
Prevented fires after net, 22- screen pack, 3- protective covers, 5- elastic washers.
Embodiment
Refering to accompanying drawing 1-4, a kind of hazardous materials transportation vehicle exhaust pipe with cooling fire-proof function, including offgas duct 1, fire prevention
The two large divisions of filter 2；Fire prevention filter 2 is placed in the inside of offgas duct 1；Halfpace is provided with inside the right-hand member of offgas duct 1, it is described
Fire prevention filter 2 is placed in offgas duct 1, halfpace of the left end in offgas duct 1, is set in the middle of halfpace with fire prevention filter 2
Flexible packing ring 5；The fire prevention filter 2 is made up of preceding fire prevention screen pack 21 and rear fire prevention screen pack 22.Described fire prevention
The right-hand member of filter 2 is provided with protective cover 3, and elastic washer 5 is provided with the middle of protective cover 3 with fire prevention filter 2.Prevented fires before described
Filter screen 21 is in spider reticulation type, and the rear fire prevention screen pack 22 is in mesh-like, by wire, asbestos fibre or glass fibre system
Into.Distance is 20mm-50mm between preceding fire prevention screen pack 21 and rear fire prevention screen pack 22.Described cooling liquid inlet 41 and cooling
The quantity of liquid outlet 42 is more than 1.The aperture of the protective cover 3 is identical with fire prevention filter 2, and in circular hole.Protective cover 3
Design play a part of protection fire prevention filter 2.
The invention employs fire prevention filter, with the function of eliminating the Mars carried secretly in tail gas or spark, can ensure that most
Mars is will be free from the tail gas ejected eventually, so as to ensure the security of transport vehicle.And cooling, fire prevention are an entirety,
Be not in a series of problem as additional flash hider on automobile blast pipe itself.
Screen pack of preventing fires is acted on, and Mars passes through the forward and backward screen pack of fire prevention filter, in the presence of forward and backward screen pack,
Mars can also extinguish in fire prevention filter.Flame damper causes blast pipe to have fire-proof function, and service behaviour is protected, so that
Ensure that the tail gas that gets into the air will not be mingled with Mars, hereby it is ensured that hazardous materials transportation car will not it is too high because of Tail Pipe Temperature or
Cause security incident with Mars in tail gas.
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.
