Device for controlling thickness of burning oil layer

Abstract

The invention discloses a device for controlling the thickness of a burning oil layer. The device comprises a burning oil pool, a communication oil pool, an oil storage pool, an oil baffle slant wall and an indirect oil supply pool. The communication oil pool is communicated with the burning oil pool through a communication pipe. The oil storage pool is arranged outside the communication oil pool and used for receiving oil overflowing out of the communication oil pool. The upper end of the annular oil baffle slant wall is connected with the upper edge of the communication oil pool. The indirect oil supply pool is arranged above the oil storage pool and communicated with the communication oil pool through an oil supply pipe. According to the device for controlling the thickness of the burning oil layer, the indirect oil supply pool is arranged above the communication oil pool and supplies the oil to the communication oil pool constantly through the oil supply pipe, so that the oil overflows out of the communication oil pool all the time, it is guaranteed that the level of the oil in the communication oil pool is relatively unchanged, and then it is guaranteed that the level of the oil in the burning oil pool is unchanged. Thus, the thickness of the burning oil layer can be accurately controlled, the sensitivity of the device is improved, and the application range of the device is widened.

Description

technical field [0001] The invention relates to the field of fire research, in particular to a device for controlling the thickness of a burning oil layer. Background technique [0002] At present, the simple device for controlling the thickness of the combustion oil layer is composed of a combustion oil pool, a connecting hose, and an oil supply pool. The connecting hose communicates the combustion oil pool with the oil supply liquid pool, and controls the thickness of the combustion oil layer of the combustion oil pool through the oil supply liquid pool. Usually, the oil supply pool is relatively large, and during the period of oil combustion in the combustion oil pool, due to the continuous replenishment of the oil supply pool, the liquid level drop in the combustion oil pool is small, and the thickness of the oil layer is approximately considered to be constant. In this way, in fire science, it is possible to study the combustion law of oil under the condition of fixed ...

AI Technical Summary

Problems solved by technology

However, there are two problems with this device: one is that when the diameter of the combustion oil pool increases, in order to improve the control accuracy, the diameter of the oil supply liquid pool must increase accordingly. However, when studying the problem of large-scale pool fire, the fuel supply The size of the liquid pool is limited and usually cannot meet the above requirements

The second is that although the heights of the combustion oil pool and the oil supply pool are equal, there is a problem that the liquid levels of the two oil pools drop at the same time. In some studies that require high precision, such as thin-layer fire research, this device will appear larger. error

Therefore, in the current fire science experiments, it is usually difficult to ensure the control accuracy when it comes to controlling the burning thickness of thin oil layers.
