Description

Technical Field

[0001] This application relates to the field of fire safety technology, and in particular to an experimental apparatus for testing the extinguishing of liquor fires. Background Technology

[0002] During the production, brewing, storage, and preservation of baijiu (Chinese liquor), large-capacity earthenware jars containing high-alcohol-concentration spirits are stored in concentrated quantities, requiring strict adherence to relevant fire prevention requirements. Currently, the most common fire extinguishing method in baijiu cellars is high-pressure fine water mist fire suppression.

[0003] Existing technical solutions mainly fall into two categories: extinguishing fires through pure fine water mist and relying on physical action; and extinguishing fires through a full-scale simulation experiment that studied the characteristics of alcohol pool fires in small chambers under the combined action of fine water mist and mechanical ventilation, as well as the effects of mechanical ventilation and wind speed on the suppression of alcohol pool fires by fine water mist. Additionally, fires are extinguished through a combination of chemical and physical action by adding additives to fine water mist.

[0004] Both types of fine water mist fire extinguishing operate on the principles of efficient cooling and rapid suffocation. When the fine water mist is sprayed into the fire, the small droplets vaporize upon heating, absorbing a large amount of heat from the fire area. This causes the surface temperature of the materials to drop rapidly, interrupting thermal decomposition. Simultaneously, the water vapor formed by the vaporization displaces air from the fire area, reducing the oxygen content around the burning material. This inhibits or interrupts combustion due to oxygen deficiency. Furthermore, the water vapor quickly envelops the burning material, flames, and smoke, blocking their heat radiation to surrounding objects and preventing the spread of flames. Larger, high-impact droplets impact the surface of the burning material, wetting it and thus inhibiting the spread and development of the fire.

[0005] However, the fire extinguishing effect of fine water mist is unstable because the main component of baijiu is high-concentration ethanol, which can be miscible with fine water mist to form low-concentration ethanol that continues to burn. Furthermore, since both are liquids, the low-concentration ethanol formed after mixing can easily flow and cause other objects in the vicinity to be ignited. At the same time, fine water mist fire extinguishing will introduce water and other impurities into baijiu, which will not only reduce the value of baijiu, but may also increase the health and safety risks of baijiu.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0027] The orientations or positional relationships indicated by terms such as "upper," "lower," "left," "right," "middle," "longitudinal," "transverse," "horizontal," "inner," "outer," "radial," and "circumferential" used in this specification are based on the orientations or positional relationships shown in the accompanying drawings and are only for the purpose of simplifying the description.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] The fire extinguishing effect of fine water mist is unstable because the main component of baijiu is high-concentration ethanol, which can be miscible with fine water mist to form low-concentration ethanol that continues to burn. Since both are liquids, the low-concentration ethanol formed by mixing can easily flow and cause other objects in the vicinity to be ignited. At the same time, fine water mist fire extinguishing will introduce water and other impurities into baijiu, which will not only reduce the value of baijiu, but may also increase the health and safety risks of baijiu.

[0029] To solve the above problems, refer to Figures 1-3 , Figure 1 The diagram shows a structural schematic of an experimental apparatus used to test extinguishing fires involving liquor. Figure 2 This diagram illustrates the structure of a combustion assembly according to an embodiment of this application. Figure 3 This diagram illustrates the structure of a gas fire extinguishing assembly provided in an embodiment of this application.

[0030] This application provides an experimental apparatus for testing the extinguishing of liquor fires, including a test chamber 1, a combustion component 2, a gas extinguishing component 3, a monitoring component, and an observation component.

This application does not limit the volume of the test chamber 1; in one example, the dimensions of the test chamber 1 are 5m × 2.4m × 2.9m. The test chamber 1 has an inner cavity for testing liquor fires. The combustion component 2 is located within the inner cavity of the test chamber 1, and liquor is placed inside the combustion component 2, which ignites during the test. One end of the gas extinguishing component 3 extends into the interior of the test chamber 1, meaning the gas extinguishing component 3 can extinguish the fire inside the test chamber 1. The gas used in the gas extinguishing component 3 is carbon dioxide or other inert gas. A monitoring component is connected to the test chamber 1 and is used to monitor the temperature and / or gas concentration and / or flame state inside the test chamber 1 to understand the situation inside the test chamber 1. An observation component is located on the wall of the test chamber 1, allowing the operator to observe the state inside the test chamber 1 at any time to judge the effectiveness of the fire extinguishing.

[0032] This application utilizes an experimental apparatus for testing the extinguishing of liquor fires to simulate the entire process of liquor fire combustion and gas extinguishing of liquor warehouse fires. It allows for real-time visual observation of the liquor fire combustion and extinguishing process, as well as real-time monitoring of fire temperature and / or CO2, O2, CO concentrations and / or flame status. By comparing different fire source intensities, including extinguishing delay start time, gas injection flow rate, gas injection time, carbon dioxide parameters, and nozzle spacing, and analyzing the changing patterns of temperature and other parameters, the optimal gas extinguishing scheme for liquor warehouse fires can be identified, providing a fire extinguishing strategy for liquor warehouse fires. Furthermore, this application employs gas extinguishing, which, compared to fine water mist extinguishing, improves the extinguishing effect without affecting the value of the liquor, thus reducing safety hazards.
