specific Embodiment

[0020] See figure 1 , the maximum capacity of the experimental balance 14 is 34kg, and the accuracy is 0.1g. The weighing platform transmits the received pressure change to the data acquisition module and inputs it into the computer. After conversion, the output quality changes with time. The signal of the data acquisition time The interval is 1s. The system structure is composed of three layers of support surfaces, 11 is the top fuel storage tank support plate, 12 is the fuel supply tank support plate, and 13 is the bottom fuel storage tank support plate, and the top fuel storage tank 31 and the fuel supply tank are respectively placed from top to bottom. 24 and underlying fuel storage pool 37. The structural support frame is welded by 20mm×20mm stainless square steel, and the overall size is 40cm×40cm×100cm.

[0021] See figure 2 , The fuel supply system is a simple connector device. The fuel supply pool 24 and the combustion pool 21 are connected by pipelines. Consider...

Abstract

The invention provides a combustion experimental facility capable of realizing continuousness and stability of liquid level. A main body of the experimental facility consists of a fuel supply system, an overflow system and a weighing system, wherein the fuel supply system comprises a top fuel storage pond and a supplied fuel pond which are connected with each other via a stainless steel hose; a valve on the stainless steel hose can control the rate of oil which flows into the supplied fuel pond from the top fuel storage pond; the overflow system comprises the supplied fuel pond and a bottom fuel storage pond which are connected with each other through a stainless steel hose; and the weighing system comprises a balance and a system frame. The experimental facility keeps fire combustion liquid level of a combustion pond stable, the liquid level of the combustion pond can be controlled by adjusting the height of the supplied fuel pond, an adjusting system is flexible and convenient, and accuracy is high. Moreover, experimental combustion rate can be measured by the high-precision balance.

Description

technical field [0001] The invention belongs to the technical field of fire safety, and in particular relates to a combustion experiment device capable of realizing continuous and stable liquid level, which is a simple and easy-to-operate experimental research equipment capable of adjusting and controlling the liquid level at different heights and measuring mass burning rate at the same time. Background technique [0002] In the field of fire science and combustion research technology, the combustion behavior of fuel pool fire is a very important research content. The hazards of fuel pool fire are closely related to its fire characteristics. Fuel pool fires usually develop rapidly, easily form explosive fires and large-scale flowing fires, are difficult to extinguish, and re-ignition is common, causing immeasurable direct and indirect economic losses. For example, on July 11, 2011, a fire accident occurred in the refinery of CNOOC in Daya Bay Petrochemical Zone, Huizhou, Gua...
