Description
Technical field
The utility model relates to fire-fighting equipment technical field, in particular to a kind of fire-fighting ventilation shafts.
Background technique
Smoke control system is the general name of fume-resisting system and smoke evacuation system.Fume-resisting system using mechanism contact type sensor mode or
Natural ventilation system prevents flue gas from entering the system of fire escape；Smoke evacuation system uses mechanical smoke extraction mode or gravity-flow ventilation side
Flue gas is drained into the system outside building by formula.All it is by supply and exhaust pipe, pipe well, fire resisting damper, Opening-closing equipment for door, send, exhaust blower
Etc. equipment composition.Ventilation shaft is the air grid optimization metal or compound pipeline complex pipeline of industry with civil buildings, is to make
Air circulation reduces harmful gas concentration.But existing ventilation shaft does not have air-cleaning function currently on the market, it has not been convenient to
It is fixedly mounted, pipeline lacks fire prevention measure, when fire occurs, it is possible to lead to the smog of discharge or harmful gas in other sources
Body is entered by air-supply passage, to damage to scene of fire people is locked into.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technical problem, is provided a kind of with air filtering function
Fire-fighting ventilation shaft.
In order to solve the above technical problems, technical solution provided by the utility model is a kind of fire-fighting ventilation shaft, feature
Be: the flange including pipe main body and both ends, the flange are equipped with connecting hole, the outer surface of the pipe main body and flange
On be coated with flame retardant coating, the pipe main body inner wall is equipped with card slot, and the card slot is embedded with dismountable active carbon filtering
Net, the activated charcoal strainer are equipped with the buckle matched with card slot 5, and the pipe main body two sides are equipped with L-type fixing piece, institute
State mounting hole there are two setting on L-type fixing piece.
Preferably, the pipe main body is made of galvanized steel plain sheet.
Preferably, the flame retardant coating is gypsum base fire-retardant fireproof coating.
Preferably, the L-type fixing piece is fixed by self-tapping screw and pipe main body.
The utility model has the advantages that compared with prior art can purify the air being sent by pressure fan, keep away
Exempt to damage people, the flame retardant coating on pipe main body outer surface can play flameproof protection, anti-corrosion, antirust, acid and alkali-resistance, prevent
A variety of effects such as smog, and fixed -piping is facilitated by L-type fixing piece.
Detailed description of the invention
Fig. 1 is a kind of fire-fighting ventilation duct structure schematic diagram of the utility model.
Fig. 2 is a kind of pipe main body schematic diagram of internal structure of fire-fighting ventilation shaft of the utility model.
Fig. 3 is a kind of activated charcoal strainer attachment structure schematic diagram of fire-fighting ventilation shaft of the utility model.
It is as shown in the figure: 1, pipe main body, 2, flange, 3, connecting hole, 4, flame retardant coating, 5, card slot, 6, activated charcoal strainer,
7, it buckles, 8, L-type fixing piece, 9, mounting hole, 10, self-tapping screw.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
In conjunction with attached drawing, a kind of fire-fighting ventilation shaft, it is characterised in that: described including pipe main body 1 and the flange at both ends 2
Flange 2 is equipped with connecting hole 3, is coated with flame retardant coating 4, the pipe main body on the outer surface of the pipe main body 1 and flange 2
1 inner wall is equipped with card slot 5, and the card slot 5 is embedded with dismountable activated charcoal strainer 6, and the activated charcoal strainer 6 is equipped with
The buckle 7 matched with card slot 5,1 two sides of pipe main body are equipped with L-type fixing piece 8, set on the L-type fixing piece 8 there are two
Mounting hole 9.
The pipe main body 1 is made of galvanized steel plain sheet.
The flame retardant coating 4 is gypsum base fire-retardant fireproof coating.
The L-type fixing piece 8 is fixed by self-tapping screw 10 and pipe main body 1.
More piece pipe main body can be connected to a fixed by the utility model by flange, pass through L-type fixing piece for pipeline
Main body and building are fixed, and activated charcoal strainer is usually required to be mounted at final section namely close to a section pipe of final ventilation opening
In road, and activated charcoal strainer is detachably connected by buckle and the card slot realization in pipeline, daily dimension very convenient in this way
Shield, guarantees purification air that can be effective when causing danger.Activated charcoal strainer uses the aluminum honeycomb of through-hole structure, modeling
Expect that honeycomb, paper honeycomb are carrier.Compared with conventional carbon filter screen, there is more excellent aerodynamics performance, volume is close
Small, large specific surface area, adsorption efficiency height are spent, air resistance coefficient is small.Alveolate activated carbon strainer is to upload attached powder in polyurethane foam
Shaped activated carbon is made, and phosphorus content is in 35%-50% or so.The active efficient absorption property of charcoal, can be used for air cleaning,
Remove the pollutant in volatile organic compounds formaldehyde, toluene, hydrogen sulfide, chlorobenzene and air.Air drag is small, and low energy consumption,
Can under certain air quantity deodorization, eliminate the unusual smell, environment purification, have good clean-up effect.Pipeline external surface is coated with gypsum base resistance
Fireproof coating is fired, it is a variety of that flameproof protection, anti-corrosion, antirust, acid and alkali-resistance, protection from fumes etc. can be played the role of simultaneously, and itself is also
With decoration function, the aesthetics of material is not interfered with.
The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing
Be also one of the embodiments of the present invention, actual structure is not limited to this.All in all if this field
Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with
The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
