Description
Technical Field
The utility model relates to a fire safety technical field especially relates to an adopt three-dimensional goods shelves of superfine dry powder fire extinguishing agent and fire extinguishing survey device thereof.
Background
The fire extinguishing modes of the fire models used at present can be mainly divided into two categories in general: extinguishing fire in a total flooding mode or locally applied mode. Full me does not put out a fire indicates that in the time of regulation, sprays the fire extinguishing agent of certain concentration to the guard area to make it evenly be full of whole guard area and put out a fire. While the local protection application extinguishes fire by directly spraying a certain amount of fire extinguishing agent to an object to be protected. Generally, when the used space is not totally closed and the opening reaches a certain proportion, the fire cannot be extinguished according to a total flooding mode, but a fire extinguishing model is designed according to a local application mode, so that the reliability of fire extinguishing can be ensured. Extinguishing fires using topical application requires several aspects to be ensured: 1. the fire extinguishing agent released by the nozzles or other spray elements should be able to cover the entire protected object; 2. the spray should have a certain intensity (the specific spray intensity should be designed according to the protected object); 3. a certain injection time is guaranteed. In general, a total flood mode extinguishes fire with a concentration of fire suppressant, while a topical application mode extinguishes fire with a strength of fire suppressant.
The space range protected by the total flooding fire extinguishing mode is large, and the mode is well applied to gas fire extinguishing agent products at present. The superfine dry powder extinguishing agent has small grain size, light weight and good flowability, and can be suspended in air for a certain time, so that the full-submerged fire extinguishing can be realized. The dry powder fire extinguishing agent is the only dry powder fire extinguishing agent which can realize a gas-like total flooding fire extinguishing mode at present, so that all places in a use area can be well protected. Therefore, the superfine dry powder fire extinguishing agent is always used for extinguishing fire in a full-flooding manner.
However, with the development of the technology, the superfine dry powder fire extinguishing agent can be successfully applied to the fields of cable trench protection, power distribution rooms and petrochemical industry, and can also be applied to fire protection of other civil buildings and military facilities, such as large-space or non-fully-enclosed places, such as production workshops, material warehouses, oil depots, power transformation and distribution stations, cable tunnels, cable shafts, mines, ports and docks, missile launching sites, hangars, ships and naval vessels, petroleum and chemical production and storage. These new sites of use also place new demands on the type of fire extinguishing application of ultra fine powder fire extinguishing agents, and many protected areas require the use of topical application to protect specific objects. For example: when the ultra-fine powder fire extinguishing agent is used for protecting certain objects in a specified storage space (a certain area in a large storage space) or is used for protecting special materials in a production workshop or a port and pier, because the space of the area is large, the fire extinguishing by using a full flooding mode requires a large amount of fire extinguishing agent and is difficult to realize, so that the fire extinguishing agent can be completely applied to the material to be protected by using a local application mode to completely cover the protected object, and further, the best fire extinguishing effect and the highest fire extinguishing efficiency can be achieved. The fire fighting of the three-dimensional shelf fire becomes the main application mode and the important research field of the fire extinguishing agent.
Therefore, in order to measure the ability of the superfine dry powder extinguishing agent to extinguish the fire on the three-dimensional shelf in a local application manner, the technical staff in the field needs to solve the problem of providing the three-dimensional shelf using the superfine dry powder extinguishing agent and the fire extinguishing measuring device using the three-dimensional shelf.
