Car, water-powder universal fire truck) utilization rate on duty and fire fighting and rescue efficiency.For lack water source disposal scene and with it is specific
Disposal object provide countermeasure means, the popularization and application of such combined complete are efficient, environmentally friendly disposal hazardous chemical thing
Therefore, there is provided technical method and disposal means.
The present invention is applied to petrochemical production equipment, fixed roof tank, internal floating roof tank (steel material floating plate, meltable material
Floating plate), oil and gas pipeline, road transport tank car, the relative closure space fire incident emergency disposal such as cable shaft.Both can be independent
Use, also combination can be combined with foam, the cooling of dry powder water jet, by tactics such as dilution, inerting, suppression, isolation, asphyxia, coolings
Disposal is combined and is used in combination, and realizes that the variation of fire fighting and rescue means, disposal efficiency are maximized, and safety and environmental protection is optimized, and is technique disposal
The best approach being combined with fire-fighting technique and tactics and disposal means.
Brief description of the drawings
Fig. 1 is apparatus of the present invention structured flowchart；
Fig. 2 is that the present invention is applied to inner floating roof tank body structured flowchart.
Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
As shown in figure 1, including main line and four bye-passes, the end of main line connects every head of bye-pass respectively
End, the main line is constituted by setting gradually the stainless steel pipeline of 1 main line ball valve of main line lock-on connection 2, and main line head end is
Air inlet；The bye-pass by set gradually branch road ball valve 3, stream valve 4, pressure gauge 5, branch road lock-on connection 6 stainless steel pipeline
Composition, bye-pass end is gas outlet.
Application Example of the invention is explained in detail below：
First, met an urgent need for fixed tank and supply the application of nitrogen：See Fig. 1,
1. fixed tank is judged for nitrogen device discharge outlet position, dry powder fire-engine is supplied nitrogen device discharge outlet distance with fixed
It is maintained within 40 meters；
2. apparatus of the present invention are positioned over and are supplied at 15-20 meters of nitrogen device discharge outlet according to fixed；
3. the air inlet of apparatus of the present invention is connected with pressure hose and is locked using snap joint, its flexible pipe is another
End is connected and is locked using snap joint with dry powder class fire fighting truck nitrogen cylinder group gas circuit house steward's inflatable interface, the hose length
30 meters；
4. apparatus of the present invention are carried into valve and manometric gas outlet (A), connect pressure hose and use lock-on connection
It is locked, its flexible pipe other end is connected and uses lock-on connection to lock admittedly with discharge outlet of the top tank fixation for nitrogen device of catching fire
It is fixed.
5. emergent confession nitrogen device 1 is carried into valve and manometric gas outlet (B--N), connect flexible pipe and connect using locking
Head is locked, and its flexible pipe other end is connected and uses locking with the top tank fixation on the top tank periphery that catches fire for the delivery port of nitrogen device
Joint is locked.
6. open dry powder class fire fighting truck nitrogen cylinder group and supply nitrogen valve, its output nitrogen pressure is controlled to：0.4 MPa；
7. apparatus of the present invention (A) valve is opened, and its output nitrogen pressure is controlled to：0.35-0.4 MPas, against cupping jar
Implement fire smothering；
8. apparatus of the present invention (B--N) valve is opened successively, and its output nitrogen pressure is controlled to：It is 0.09-0.117 MPas, right
