Abstract
The invention discloses a method for slowly and evenly distributing foam of an arched-roof storage tank. The method includes the following steps that the generated foam is conveyed through a foam injecting pipe to a foam distributing pipe; the foam distributing pipe is vertically arranged in the arched-roof storage tank; foam nozzles are arranged on the foam distributing pipe at intervals; the vertically-adjacent foam nozzles are arranged on the two sides of the foam distributing pipe in a staggered manner; and the foam in the foam distributing pipe is slowly and evenly distributed on an oil surface through the foam nozzles. By means of the method for slowly and evenly distributing the foam of the arched-roof storage tank, the foam can be effectively conveyed to the combusting liquid surface, the influences of heat flow on the foam are avoided, the foam is evenly distributed on the liquid surface, and the fire extinguishing efficiency is improved.
Description
Technical field
The present invention relates to foam when one is put out a fire and relax uniform method, specifically relate to foam when a kind of Dome roof tank is put out a fire and relax uniform method.
Background technology
Owing to cannot effectively control fire, fire extinguishing during current Dome roof tank breaking out of fire, adjacent storage usually can be caused to produce spontaneous combustion due to high temperature, even go here and there tank, consequence is hardly imaginable.Existing extinguishing method is generally high-jetting vehicle spray foam or fixed-piping and is passed to by foam after tank top along tank skin from the mode flowing into tank.The mode that high-jetting vehicle directly sprays can cause the further splash of pasta, thus strengthens the intensity of a fire, simultaneously looser owing to spraying drop point, cannot play effectively control fire, fire extinguishing in the very first time.The mode that fixed-piping flows automatically along tank skin cannot overcome the abatement of fire hot-fluid to foam usually, and cannot obtain the distribution of good foam, thus cannot effectively control fire and fire extinguishing.
Summary of the invention
Based on above-mentioned technical problem, the invention provides a kind of Dome roof tank foam and relax uniform method.
The technology used in the present invention solution is:
A kind of Dome roof tank foam relaxes uniform method, comprise the following steps: the foam of generation is delivered to foam distributing tube through foam injection pipe, foam distributing tube is vertically arranged in Dome roof tank inside, foam distributing tube is arranged at intervals with foam jet, neighbouring foam jet interlaced arrangement is in the both sides of foam distributing tube, and the foam in foam distributing tube is relaxed by foam jet and is distributed on pasta uniformly.
Preferably, described foam distributing tube arranges multiple, and described multiple foam distributing tube is uniformly distributed along the border of Dome roof tank.
Preferably, described foam distributing tube at least arranges 4.
Advantageous Effects of the present invention is:
Foam can be effectively delivered to burning liquid level by the present invention, overcomes the impact of hot-fluid on foam, is evenly distributed on by foam on liquid level, improves fire-fighting efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and detailed description of the invention, the invention will be further described:
Fig. 1 realizes the structural representation that Dome roof tank foam of the present invention relaxes a kind of device for carrying out said of uniform method;
Fig. 2 is the top view of Dome roof tank in Fig. 1, and the distribution of foam distributing tube in Dome roof tank is mainly shown.
In figure: 1-Dome roof tank, 2-foam distributing tube, 3-foam jet, 4-foam injection pipe, 5-pasta.
Detailed description of the invention
For the deficiency that existing Dome roof tank extinguishing method exists, the invention provides and a kind ofly can to overcome among injection storage tank that scene of a fire hot-fluid impact makes foam relax to concentrate, be uniformly distributed in the method for liquid level, thus put out a fire efficiently.
A kind of Dome roof tank foam relaxes uniform method, comprise the following steps: the foam of generation is delivered to foam distributing tube through foam injection pipe, foam distributing tube is vertically arranged in Dome roof tank inside, foam distributing tube is arranged at intervals with foam jet, neighbouring foam jet interlaced arrangement is in the both sides of foam distributing tube, and the foam in foam distributing tube is relaxed by foam jet and is distributed on pasta uniformly.
Above-mentioned foam distributing tube arranges multiple, and described multiple foam distributing tube is uniformly distributed along the border of Dome roof tank.
The inventive method need coordinate existing foam-making apparatus, and main purpose is that foam is effectively delivered to burning liquid level, high-effect fire-extinguishing.The present invention is made foam relax by the method for fixed-piping (foam distributing tube) preset in Dome roof tank and is evenly distributed on pasta, thus foam is effectively put out a fire.In the present invention, the bore of preset fixed-piping and distribution form, specifically specifically can be arranged according to after the volume of Dome roof tank and the substance combustion stored calorific value calculation.
Below with reference to the device shown in accompanying drawing, the invention will be further described:
Fig. 1 realizes the structural representation that Dome roof tank foam of the present invention relaxes a kind of device for carrying out said of uniform method; Fig. 2 is the top view of Dome roof tank in Fig. 1, and the distribution of foam distributing tube in Dome roof tank is mainly shown.Foam mitigation is mainly distributed on liquid level by built-in foam distributing tube by the present invention uniformly as seen from the figure, thus effectively puts out a fire.
By the top view layout of Fig. 2 mono-preferred embodiment volume of this preferred embodiment known according to Dome roof tank 1 and the combustion characteristics of storing liquid, be provided with the foam distributing tube 2 that four are built in Dome roof tank, to reach sufficient foam distribution fire extinguishing.
As shown in Fig. 1 mono-preferred embodiment structure chart, the present invention is that the foam utilizing foam injection pipe 4 to be generated by foam-making apparatus is delivered in four foam distributing tube 2, further by foam jet 3, foam is delivered to pasta 5 by it again, reaches the effect of fire extinguishing.
This foam distributing tube 2 is arranged at intervals with several foam jets 3, neighbouring foam jet 3 interlaced arrangement is in the both sides of foam distributing tube 2.When fire occurs, foam injects foam distributing tube 2, can effectively avoid fire hot-fluid to the bubble bad effect of foam, can directly be delivered to pasta 5 simultaneously, by nearest foam jet 3 from the pasta 5 overflow to burning, final four foams be built in the foam distributing tube of Dome roof tank are evenly distributed on pasta 5, reach efficient fire extinguishing.
The relevant technologies content do not addressed in aforesaid way is taked or uses for reference prior art to realize.
It should be noted that, under the instruction of this description, those skilled in the art can also make such or such easy variation pattern, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should within protection scope of the present invention.
