Description
Technical field
The present invention relates to inflammable gas transfer pipeline anti-backfire technical field of safety devices, more particularly to a kind of dry type is certainly
By base fire retardant device.
Background technology
, it is necessary to prevent flare from channeling to source of the gas end using holding back during the use of inflammable gas, in order to avoid cause source of the gas
The security risk at end, traditional fire retardant device uses single liquid anti-backfire tank, that is, allow tempering to be realized by liquid
The purpose of flare is eliminated, but in actual use, it is very fast to return the flare speed altered, particularly hydrogen and oxygen gas mixture, is returning
In the process of fire, substantial amounts of free radical, flare can be produced to carry a large amount of free radicals time and alter, disappeared when the quantity that free radical increases is more than
During the quantity gone out, gas will spontaneous combustion, therefore, depend alone liquid anti-backfire tank can not completely isolated flare return alter, do not reach peace
The full requirement for using.
The content of the invention
In view of the shortcomings of the prior art, the present invention is intended to provide a kind of dry type free radical fire retardant device, eliminates drawing process
In a large amount of free radicals, the purpose of back-fire relief can be functioned well as.
To achieve the above object, the present invention is adopted the following technical scheme that：A kind of dry type free radical fire retardant device, the dry type
Free radical fire retardant device is connected between inlet end and outlet side, it is characterised in that：The dry type free radical fire retardant device includes
" W " shape seal pipe of one or more parallel connection, the serpentine-like bending of central axis of the every seal pipe, the every seal pipe
Including the first " u "-shaped pipe and the second " u "-shaped pipe, first " u "-shaped pipe is adjacent to the inlet end, and second " u "-shaped pipe is adjacent
The nearly outlet side, filling wire in filling sand grains, second " u "-shaped pipe in first " u "-shaped pipe.
Preferably, the every seal pipe is welded by the arc tube of the identical caliber of multistage, arc tube described in every two it
Between seamlessly transit, the arc chord angle of the arc tube is 45 degree or 90 degree.
Preferably, the sand grains of filling is quartz sand in first " u "-shaped pipe.
Preferably, the wire of filling is 316 stainless steel wires in second " u "-shaped pipe.
Preferably, the in disorder setting of 316 stainless steel wires filled in second " u "-shaped pipe.
Preferably, gap is provided between the every seal pipe and is easy to cooling, the seal pipe side is additionally provided with a blower fan
For lowering the temperature.
The present invention has the advantages that：
The present invention is set using the seal pipe of " W " shape, can be easily filled with filler, the second " u "-shaped of neighbouring outlet side
The full stainless steel wire of filling, when there is tempering, can stop the most of free radical come from outlet side in pipe, and free radical hits
Hit in stainless steel wire, and stainless steel wire absorbs；The full quartz sand of first " u "-shaped pipe filling of neighbouring inlet end, quartz sand has very
Good heat absorption function, so remaining free radical is given by quartz sand absorb, so as to serve the purpose of back-fire relief；In addition, seal pipe
Central axis it is serpentine-like, so free radical enter seal pipe in when, can constantly with tube wall collide and absorbed, improve sealing
Pipe eliminates the efficiency of free radical.
Brief description of the drawings
Fig. 1 is three-dimensional structure diagram of the present invention；
Fig. 2 is connection diagram of the invention；
In figure：1- seal pipes, the " u "-shaped pipes of 11- first, the " u "-shaped pipes of 12- second, 2- blower fans, 3- inlet ends, 4- outlet sides.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the invention will be further described, and this is understood in order to clearer
The claimed technological thought of invention.
A kind of reference picture 1, Fig. 2, dry type free radical fire retardant device, the dry type free radical fire retardant device is connected to inlet end
Between 3 and outlet side 4, the dry type free radical fire retardant device includes " W " the shape seal pipe 1 of one or more parallel connection, every institute
The serpentine-like bending of central axis of seal pipe 1 is stated, can so allow free radical in drawing process constantly to collide tube wall and inhaled
Receive, the every seal pipe 1 includes the first " u "-shaped pipe 11 and the second " u "-shaped pipe 12, the first " u "-shaped pipe 11 and the second " u "-shaped pipe
12 is in smoothing junction, first " u "-shaped pipe 11 adjacent to the inlet end 3, second " u "-shaped pipe 12 adjacent to the outlet side 4,
Filling sand grains in first " u "-shaped pipe 11, is preferably to fill up filling wire in quartz sand, second " u "-shaped pipe 12, most
316 in disorder stainless steel wires are to fill up well, and 316 stainless steel wires are very thin very thin, increase the collision probability of free radical, further
Absorb free radical.
Specifically, the every seal pipe 1 is welded by the arc tube 13 of the identical caliber of multistage, every two sections of circular arcs
Seamlessly transitted between pipe 13, be so beneficial to the intensity of arc tube 13, be also convenient for filling in filler, every two sections of arc tubes 13
Solder side is plane, convenient welding, and during welding, two sections of centers of circle of the arc tube 13 are located at its both sides respectively so that seal pipe 1
Central axis it is serpentine-like, the arc chord angle of the arc tube 13 is 45 degree or 90 degree, specifically, the upper and lower side corner of seal pipe 1
Arc tube 13 be in 90 degree, remaining all be 45 degree.
Specifically, gap is provided between the every seal pipe 1 is easy to cooling, the side of all seal pipes 1 is additionally provided with
One blower fan 2 provides air-cooled, and the free radical produced in drawing process absorbs layer by layer, so as to play good back-fire relief effect.
During present invention work, the flare altered is returned by the second " u "-shaped pipe 12, mixed and disorderly 316 are filled up in the second " u "-shaped pipe 12
Stainless steel wire, so that most free radical is absorbed, and the axis of seal pipe 1 is snakelike setting, free radical is easy to collision
It is partially absorbed to tube wall, then enters back into the first " u "-shaped pipe 11, quartz sand is filled with the first " u "-shaped pipe, quartz sand has
Heat absorption function, adds outside to the air-cooled of seal pipe 1 well, accelerates the extinguishing of tempering flare and the elimination of free radical, so that
Play the effect of good anti-backfire.
The examples of implementation of the above are only the preferred embodiments of the invention, not limit implementation model of the invention with this
Enclose, therefore the change that all shapes according to the present invention, principle are made, all should cover within the scope of the present invention.
