Measurement device for self-repairing performance of firefighting foam and experiment method

Abstract

The invention discloses a measurement device for the self-repairing performance of firefighting foam and an experiment method. A main body of the device is a quartz glass container with a top opening;the quartz glass container is internally provided with a water outlet, a sealing ring and a push-pull rod; the water outlet is connected with a water discharging pipe provided with a valve; the push-pull rod is clamped through a clamp fixed at the bottom of the quartz glass container; the upper end of the push-pull rod is connected with a quartz glass column; a fuel liquid inlet is arranged at aside edge of the quartz glass container; the fuel liquid inlet is connected with a fuel liquid inlet pipe; the fuel liquid inlet pipe is provided with a valve, a flow controller, a pressure gauge, a pressure pump and a fuel box in sequence; a foam liquid inlet pipe and a high-speed camera are arranged at a top opening of the quartz glass container; the high-speed camera is connected with a computer and is fixed through a fixed iron frame; and the foam liquid inlet pipe is connected with the valve, the flow controller and a foam generator in sequence. The measurement device disclosed by the invention can provide technical supports for estimating the self-repairing performance of the different firefighting foam better.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting supplies, and in particular relates to a measuring device and an experimental method for the self-repairing performance of fire-fighting foam. Background technique [0002] Firefighting foam is the most common and effective method of fighting Class B (liquid) fires. The fire-fighting foam can cover the surface of the burning fuel to form a foam layer with a certain thickness, which plays the role of cooling and extinguishing the fire. In addition, a certain thickness of the fire-fighting foam layer can also prevent the overflow of fuel vapor below, and this effective sealing effect makes the fire-fighting foam have good anti-resurgence performance. [0003] The self-healing property of fire-fighting foam refers to the ability of fire-fighting to automatically repair breaches. During the fire extinguishing process, the fire-fighting foam covered on the fuel will have a certain degree of bre...

Problems solved by technology

At present, domestic and foreign literatures mostly ignore the self-healing properties of fire-fighting foams when studying the properties of fire-fighting foams, and there is still a lack of measuring devices and experimental methods for the self-healing properties of fire-fighting foams at home and abroad.
