Embodiment 1

[0062] A test method for foam covering disposal of volatile and flammable liquids, the steps are as follows,

[0063] In the first step, put 20kg of fluoroprotein 3% anti-solubility water film-forming foam fire extinguishing agent A stock solution in the foam storage tank, which is a closed container, and install a valve with a flange at the outlet of the foam storage tank;

[0064] In the second step, add enough water to the 500L water storage tank, and the outlet of the water storage tank is connected to the one-way valve;

[0065] The third step is to open the one-way valve, start the delivery pump, water flows through the flow meter, adjust the water flow to 80L / min, the water supply pressure to 0.8MPa, and the foam expansion ratio to 6.5;

[0066] The fourth step is to open the valve, and the foam will flow through the valve in the form of negative pressure self-priming, and then mix and foam with water at the foam spray gun. During the process, ensure a certain flow rat...

Embodiment 2

[0074] In the first step, put 20kg of fluoroprotein 3% anti-solubility water film-forming foam fire extinguishing agent B stock solution in the foam storage tank, which is a closed container, and install a valve with a flange at the outlet of the foam storage tank;

[0075] In the second step, add enough water to the 500L water storage tank, and the outlet of the water storage tank is connected to the one-way valve;

[0076] The third step is to open the one-way valve, start the delivery pump, water flows through the flow meter, adjust the water flow to 70L / min, the water supply pressure to 0.8MPa, and the foam expansion ratio to 9.5;

[0077] The fourth step is to open the valve, and the foam will flow through the valve in the form of negative pressure self-priming, and then mix and foam with water at the foam spray gun. During the process, ensure a certain flow rate when the water flows through the foam spray gun, and ensure that the foam pipeline is in a certain negative pr...

Embodiment 3

[0085] A test method for foam covering disposal of volatile and flammable liquids, the steps are as follows,

[0086] In the first step, put 30 kg of fluoroprotein 3% anti-solubility water film-forming foam fire extinguishing agent A foam fire extinguishing agent stock solution into the foam storage tank, the foam storage tank is a closed container, and the outlet of the foam storage tank is installed with a valve with a flange;

[0087] In the second step, add enough water to the 500L water storage tank, and the outlet of the water storage tank is connected to the one-way valve;

[0088] The third step is to open the one-way valve, start the delivery pump, water flows through the flow meter, adjust the water flow to 150L / min, the water supply pressure to 0.7MPa, and the foam expansion ratio to 12;

[0089] The fourth step is to open the valve, and the foam will flow through the valve in the form of negative pressure self-priming, and then mix and foam with water at the foam s...

Abstract

The invention provides a test device and method for treating volatile and inflammable liquid through foam coverage. The device comprises a flammable liquid storage device, a foam spray gun, a foam storage device and a water storage device, the foam storage device and the water storage device are communicated with the foam spray gun through pipelines, a weighing device is arranged on the flammableliquid storage device, and the weighing device is electrically connected with a computer used for receiving and processing data transmitted by the weighing device. The experimental equipment is simple, a complex foaming system is not needed, obtained data can be transmitted to a computer in real time to be processed, and then the coverage effect is evaluated. The method has a promoting effect on the development of a liquid dangerous chemical leakage disposal technology. Through the development of a coverage disposal technology, the accident consequence loss is reduced to the maximum extent, and the leakage emergency disposal capacity of an emergency rescue team is improved.

Description

technical field [0001] The invention belongs to the field of fire-fighting test devices, and in particular relates to a test device and method for foam covering and disposing of volatile and flammable liquids. Background technique [0002] The statistics of typical accidents of hazardous chemicals show that flammable liquids have the most accidents. Leakage of flammable / toxic liquids often forms a large-area liquid pool, which spreads continuously to the surroundings and low-lying places, and is accompanied by volatilization of vapor, which makes flammable, explosive / toxic vapors gather in the air, easily forming an explosive gas atmosphere and causing great harm. harm. Therefore, for these leaked liquids, how to dispose of them quickly and effectively is very important. [0003] Compared with foreign countries, my country has already had some research and accumulation in emergency rescue and disposal technology and equipment for liquid hazardous chemical leakage accidents...
