Abstract
The utility model relates to an oxygen fire-retarding device, which belongs to the technical field of the design and manufacture of fire-retarding devices. The utility model is composed of a casing and a fire-retarding chamber, wherein the fire-retarding chamber is an inner core composed of a layer of copper belts and a layer of small-caliber copper pipes and the cross section of the fire-retarding chamber is a honeycomb form. The inner core is fixed on the two big flanges of the casing by a core casing, the outer sides of the big flanges are reducing pipes, and the other end of the reducing pipes is a small flange. The utility model has the advantages of reasonable structure, small volume and good safety, the concentrated combustion of combustion flame energy is divided into numerous small strands of combustion, and the combustion speed and energy of flames are reduced. The oxygen fire-retarding device has the effect of fire retardation, and the small flanges are arranged, which is easy for installation, overhaul and maintenance. The utility model can be used for the pipeline transportation of oxygen and can be used at the front of points where the oxygen is used, and combustion accidents are prevented from occurring.
Description
The utility model belongs to the design and fabrication technology field of flame-retardant device, refers in particular to that oxygen channel is carried and with the utensil that is used in the oxygen process to prevent burn.
In the oxygen channel conveying with in the oxygen process, the accident of oxygen combustion often takes place, even the oxygen channel explosion accident takes place.At present, in China's every profession and trade, for guaranteeing that with for the purpose of the oxygen safety only increase the housing retarding chamber that welds one section identical caliber on the oxygen pipeline, material is a red copper, as flame-retarding means.This way does not fundamentally solve fire-retardant problem, and pipeline is easily burnt out, and especially uses in the oxygen enterprise at metallurgy, and not only operation and maintenance is difficult to carry out, and does not reach flame retardant effect.
It is good that the purpose of this utility model provides a kind of flame retardant effect, and security is good, oxygen flame-retardant device easy to install.
The purpose of this utility model is achieved in that by housing and retarding chamber and constitutes that retarding chamber is the inner core that circular cross-section is a honeycomb style of copper pipe formation by ultra-thin copper strips of center of circle one deck and the extra small bore of one deck ultra-thin-wall, and inner core is outward a core housing.Core housing is fixed on the two big flanges of housing, and the two big flanges outside is two different from pipe, and the two reduced pipe other ends are little flange.Housing and retarding chamber all adopt the good silizin of fire resistance to make.
According to oxygen fire-retardant " wall effect " principle, retarding chamber is made up of numerous small sircle hole footpath runner and numerous little subtriangular aperture runner, and the fire combustion is extinguished in these numerous small-bore runners.
The utility model technical performance is:
Use intermediate value: O
2
Caliber scope: DN50～DN150mm
Flow: 800Nm
3/ n～10000Nm
3/ n
Pressure: 1.6MPa
Flow velocity: 8～10M/S
Temperature :-15 ℃～+ 200 ℃
Drag losses: 0.02～0.04MPa
The utility model has the advantages that rational in infrastructurely, volume is little, and housing and retarding chamber material are silizin, and its coefficient of heat conduction is big, and endothermic effect is good, and silicon contacts with oxygen and forms silicon oxide film, and burnback resistance is strong.Be provided with little flange, can connect and dismounting, be easy to installation, maintenance and maintenance with any caliber flange.When oxygen pipeline burns, or strile-back when burning with oxygen point, burning direction is to burn by the contrary direction of oxygen normal flow direction, the retarding chamber sectional area is 2～3 times of caliber, before combustion flame enters retarding chamber, and the hurried expansion of combustion flame volume, flow velocity slows down, and pressure reduces; When then entering numerous small-bore runner, combustion flame and plate, tube wall run foul of each other, and power conversion takes place, and have reduced flame temperature.Add the runner distance of sufficient length, absorb the combustion flame heat, combustion flame is extinguished in the runner of numerous small-bore, reach fire-retardant purpose.
The utility model is elaborated during below in conjunction with drawings and Examples.
Accompanying drawing 1 is the utility model assembly structure schematic diagram
Accompanying drawing 2 is the utility model retarding chamber inner core cross section view
This oxygen flame-retardant device is made of housing and retarding chamber, retarding chamber is to constitute a circular cross-section for being the inner core of honeycomb style (10) by the silizin pipe (12) of center of circle one deck ultra-thin silicon brass band (11) and the extra small bore of one deck ultra-thin-wall, inner core is outward core housing (8), core housing (8) is fixed on the two big flanges (5) of housing through steady pin (7) and sealing gasket (9), two big flanges (5) are fixedlyed connected with nut (3) by stud (4), pad (6), the two big flange outsides are two reduced pipes (2), and the two reduced pipe other ends are little flange (1).Can reach oxygen flame-retardant device technical performance, effect is splendid.
