Referring to fig. 1 to 8, the fire-retardant rescue apparatus for combustible liquid fire explosion includes: the device comprises a steel cylinder 1, a metal screen support frame 2, a metal screen 3, a fire-retardant seepage layer 4, a metal screen 5 and a metal screen support frame 6;
The steel cylinder 1 is of a cavity structure, one end of the steel cylinder is a liquid inlet end, and the other end of the steel cylinder is a liquid outlet end;
a metal screen support frame 2 is fixedly arranged at the liquid inlet end of the steel cylinder 1, and a metal screen 3 is fixedly arranged on the metal screen support frame 2. The metal screen 3 is used for blocking sundries in the flowing combustible liquid from flowing into the device. And the metal screen support frame 2 is used for preventing larger impurities in the flowing combustible liquid from flowing into the device and enhancing the structural strength.
A metal filter screen support frame 6 is fixedly arranged at the liquid outlet end of the steel cylinder 1, and a metal filter screen 5 is fixedly arranged on the metal filter screen support frame 6. The metal filter screen 5 is used for preventing the fire-retardant seepage layer 4 from overflowing; and the metal filter screen support frame 6 is used for enhancing the structural strength of the bottom of the flammable liquid fire explosion fire-retardant rescue device and preventing the interior of the flammable liquid fire explosion fire-retardant rescue device from collapsing.
The structure of metal screen cloth support frame 2 is the same with that of metal screen cloth support frame 6, is: the center of the end face of the steel cylinder 1 is used as a central point, a plurality of support rod parts are formed in a radial shape towards the periphery, and the other end of each support rod part is fixed to the edge of the end face of the steel cylinder 1.
the section of the steel cylinder 1 is circular or rectangular; the shapes of the metal mesh 3 and the metal screen 5 are the same as the cross-sectional shape of the steel cylinder 1.
inside the steel cylinder 1 and in the cavity between the metal screen 3 and the metal screen 5, a fire-retarding seepage layer 4 is installed. Fireproof sand is filled in a cavity between the metal screen 3 and the metal screen 5, or a plurality of layers of fine and dense steel wire meshes in the radial direction are arranged, so that a fire-retardant seepage layer 4 is formed. The fire-barrier seepage layer 4 has pores through which a combustible liquid of low viscosity flows.
the utility model also provides a back-fire relief rescue method based on flammable liquid fire explosion back-fire relief rescue device, including following step:
Step 1, preparing a plurality of flammable liquid fire explosion fire-retardant rescue devices; arranging the flammable liquid fire explosion fire-retardant rescue device around a flammable liquid storage tank or a flammable liquid warehouse; the arrangement mode of the flammable liquid fire explosion fire-retardant rescue device is as follows: the flammable liquid fire explosion fire-retardant rescue device is laid down, so that the axial direction of a steel cylinder 1 of the flammable liquid fire explosion fire-retardant rescue device is parallel to an arrangement site;
Step 2, when a flammable liquid fire occurs in a flammable liquid storage tank or a flammable liquid warehouse, the flammable liquid with low viscosity which is on fire flows into a fire-retardant seepage layer 4 after passing through a metal screen 3; the metal screen 3 is used for preventing impurities in the low-viscosity combustible liquid from flowing into the fire-retardant seepage layer 4;
according to the three conditions that combustible materials, combustion-supporting materials and temperature reach the ignition point, when low-viscosity combustible liquid which is ignited and combusted flows through the fire-retardant seepage layer 4, enough oxygen is not available, and the temperature does not reach the ignition point, so that the fire is extinguished. The specific principle is as follows:
The first point is as follows: the fire-retardant seepage layer with a certain thickness is formed by sand grains or multiple layers of fine steel wire meshes, and can isolate the radiant heat generated when outside combustible liquid is combusted, so that a convection layer cannot be formed on the liquid surface after the combustible liquid enters the fire-retardant seepage layer 4;
And a second point: when a low-viscosity flammable liquid flows in a narrow, narrow space in the fire-retarding, seepage layer 4, the surrounding material is able to absorb energy from the high-temperature flammable liquid or the flammable vapor cloud;
and a third point: the liquid flowing through the long, narrow and small space in the fire-retardant seepage layer 4 is not close to the ignition point, so that the liquid has the function of cooling;
a fourth point: because the pores in the fire-retardant seepage layer 4 are small, when low-viscosity combustible liquid flows in the fire-retardant seepage layer 4, the liquid occupies a large part, and therefore, the air in the fire-retardant seepage layer 4 is little;
And fifth, the method comprises the following steps: because the fire-retardant seepage layer 4 is long, narrow and fine in pores, an air surrounding red-hot combustible liquid surface layer cannot be formed, and the convection condition required for ignition cannot be formed;
And a sixth point: when the liquid flows in a long, narrow and small space in the fire-retardant seepage layer 4, the function of isolating the air inside and outside is achieved;
Through the six-point action, when the low-viscosity flammable liquid which is on fire flows through the fire-retardant seepage layer 4, the effects of separating oil from fire and blocking a fire source can be achieved after oxygen insulation and temperature reduction, so that the fire is extinguished;
and 3, after the extinguished low-viscosity combustible liquid passes through the metal filter screen 5, the low-viscosity combustible liquid flows out from the liquid outlet end of the combustible liquid fire explosion fire-retardant rescue device.
Therefore, the utility model provides a flammable liquid fire explosion back-fire relief rescue device, for symmetrical structure, both ends are for advancing, exporting respectively. When a fire disaster occurs, the combustible liquid passes through the metal screen support frame 2 and the metal screen 3, enters the fire-retardant seepage layer 4 (consisting of fire-retardant sand or fine steel wires, and sand with different particle sizes or gauze with different meshes can be selected according to the type of the combustible liquid), and finally flows out through the metal screen 5 and the metal screen support frame 6. After the flammable liquid passes through the flammable liquid fire explosion fire-retardant rescue device and is subjected to oxygen insulation and temperature reduction, the effects of oil-fire separation and fire source obstruction can be achieved.
The utility model provides a flammable liquid fire explosion back-fire relief rescue device can arrange around flammable liquid storage tank, warehouse etc. as fixed facilities. Also can be connected with the vacuum pump as the equipment of mobilizable flammable liquid fire explosion back-fire relief rescue, have following advantage:
The device can be reused, and the total amount of combustible liquid can be reduced, so that the total heat quantity can be controlled;
Compared with the traditional liquid fire disaster rescue mode, the utility model is more effective for liquid fire disaster rescue, can prevent large-scale flowing fire or a large amount of pool fire from accumulating, and can reduce the probability of igniting and detonating other flammable and explosive products; most of combustible liquid can extinguish the fire source through developed facilities and devices and can be stored in the tank again.
the foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be viewed as the protection scope of the present invention.
