Specific embodiment
As shown in attached drawing 1 to attached drawing 7:
A kind of canister of Novel firefighting self-rescue apparatus includes: shell 1, hollow layer 101, fixed block 102, thermal insulation layer
103, gas outlet 2, air inlet 3, the malicious layer 4 of filter, air hole 401, smoking block 402, inner groovy 403, inclined plate 5, taste removal layer 6, through-hole
601, diversion trench 602, particulate filter 7 and drying layer 8；The inside of shell 1 is embedded with hollow layer 101, and the inner wall of hollow layer 101 is fixed to be connected
It is connected to fixed block 102, the side of fixed block 102 is fixedly connected with thermal insulation layer 103, and the top of shell 1 offers gas outlet 2, shell
The bottom of body 1 offers air inlet 3, and the inner wall bottom of shell 1 is fixedly connected with the malicious layer 4 of filter, filters the surface of malicious layer 4 through connection
There is air hole 401, the inside of air hole 401 is fixedly connected with smoking block 402, and the surface of smoking block 402 is embedded with inner groovy
403, the two sides of the bottom for filtering malicious layer 4 are fixedly connected to inclined plate 5, and the top for filtering malicious layer 4 is provided with taste removal layer 6, and taste removal layer 6 is solid
Surely it is connected to the inner wall of shell 1, through through-hole 601 is connected with, the two sides of the bottom of through-hole 601 are embedded at the top of taste removal layer 6
Diversion trench 602, the top of taste removal layer 6 is provided with particulate filter 7, and the top of particulate filter 7 is fixedly connected with drying layer 8, particulate filter 7
The inner wall of shell 1 is respectively positioned on drying layer 8.
Wherein, in the case of fire, shell 1 can be made to be isolated from the outside by hollow layer 101, and passes through fixed block
102 play a supportive role to hollow layer 101 in semicircle shape, while hollow by the side of fixed block 102, make 102 inside of fixed block
The extraneous hot gas of 103 pairs of thermal insulation layer reflect, the inner wall temperature of shell 1 is reduced, convenient for the breathing of user.
Wherein, when flue gas is by filtering malicious layer 4, flue gas is first moved with air hole 401 close to the side filtered among malicious layer 4,
Since air hole 401 is corrugated, flue gas can not only be improved and filter the contact area of malicious layer 4, reducing in flue gas has poison gas
Body, moreover it is possible to barrier effect is played to flue gas by the turning point of air hole 401, make flue gas with smoking block 402 contact, to flue gas into
Row absorbs, and the contact effect of flue gas with block 402 of smoking is improved by inner groovy 403, convenient for the absorption of flue gas.
Wherein, when flue gas passes through taste removal layer 6 again, since taste removal layer 6 is corrugated, flue gas connects with taste removal layer 6
When touching, is first contacted with the trough of taste removal layer 6, since trough is convex, move flue gas to the two sides of trough, and to taste removal
It is moved at the wave crest of layer 6, then water conservancy diversion is carried out to flue gas by the diversion trench 602 of 6 bottom of taste removal layer, flue gas is made to pass through through-hole 601
Discharge can not only improve the contact area of flue gas Yu taste removal layer 6 while flue gas is moved to the two sides of trough, reduce flue gas
In odor molecules, and flue gas can also be made to pass through along diversion trench 602 in isosceles trapezoid shape by the cross section of diversion trench 602
Through-hole 601 is discharged, and is discharged convenient for the drainage of flue gas.
Wherein, oblique by inclined plate 5, and the angle of the vertical plane of inclined plate 5 and shell 1 is 45 ° -60 °, can make cigarette
Gas rapidly enters in air hole 401, and convenient for the quick filter poison of flue gas, structure is simple, and practicability is stronger.
In use, be first threadedly coupled the screw thread in 1 top gas outlet of shell, 2 outside with fire mask, in the case of fire,
So that shell 1 is isolated from the outside by hollow layer 101, and support is played to hollow layer 101 in semicircle shape by fixed block 102 and is made
With, while it is hollow by the side of fixed block 102,103 pairs of thermal insulation layer extraneous hot gas of 102 inside of fixed block are reflected,
The inner wall temperature of shell 1 is reduced, convenient for the breathing of user, while flue gas is entered by air inlet 3, passes through the filter at air inlet 3
Net stops extraneous dust, then makes flue gas by filtering poison layer 4 by inclined plate 5, and when flue gas passes through and filters malicious layer 4, flue gas is first and saturating
Stomata 401 is close to the side movement filtered among malicious layer 4, since air hole 401 is corrugated, can not only improve flue gas and filter poison
The contact area of layer 4 reduces the toxic gas in flue gas, moreover it is possible to play blocking to flue gas by the turning point of air hole 401 and make
With, make flue gas with smoking block 402 contact, flue gas is absorbed, and by inner groovy 403 improve flue gas and smoking block 402
Contact effect, convenient for the absorption of flue gas, then flue gas passes through taste removal layer 6 again, since taste removal layer 6 is corrugated, flue gas
It when being contacted with taste removal layer 6, is first contacted with the trough of taste removal layer 6, since trough is convex, transports flue gas to the two sides of trough
It is dynamic, and water conservancy diversion is carried out to flue gas to movement at the wave crest of taste removal layer 6, then by the diversion trench 602 of 6 bottom of taste removal layer, make cigarette
Gas is discharged by through-hole 601, and the contact of flue gas with taste removal layer 6 can not only be improved while flue gas is moved to the two sides of trough
Area reduces the odor molecules in flue gas, additionally it is possible to flue gas be discharged by through-hole 601 along diversion trench 602, convenient for drawing for flue gas
Stream discharge, subsequently further filters out flue gas by particulate filter 7, flue gas is dried by drying layer 8, finally by out
Port 2 is discharged, and makes the air that human body respiration is nontoxic, improves the survival ability of human body.
