Abstract

The invention discloses a mine ventilation network system experiment device and method, which are suitable for mine ventilation experiments. It consists of two main straight air ducts of equal length and parallel on the same horizontal plane, one end of which is connected to the U-shaped connecting air duct with a flange through a rectifying grille, and the other end is respectively connected to a frequency conversion centrifugal fan through a wind tunnel. The air duct on one side of the centrifugal fan is provided with an inlet flat gate, a louver valve and a bypass anti-air duct in sequence, and a vertical gate and a diffuser outlet flat gate connected with the centrifugal fan are arranged at the exit of the anti-air duct; There are connecting air ducts and circulating connecting air ducts connected in parallel between the main straight air ducts, and a vertical gate is installed in these air ducts, and a variable frequency axial flow circulating fan is installed in the middle of the circulating connecting air ducts. The invention can realize experiments of various ventilation networks and various ventilation modes, has simple structure, convenient operation, strong adjustability, multiple experimental functions and high cost performance, and can provide relatively perfect support for mine ventilation experiment teaching.

Description

technical field [0001] The invention relates to a mine ventilation experiment device and method, in particular to a mine ventilation network system experiment device and method suitable for mine ventilation experiments. Background technique [0002] Mine ventilation system is a complex system composed of mine ventilation network, ventilator and air flow control facilities, among which mine ventilation network is a complex roadway network system connected by open roadway, mining area roadway and mining roadway. Due to its complexity, the current experimental model of the mine ventilation network system is still a demonstrative fixed model. Its manufacturing process is complex, bulky, high in cost, and the functions of ventilation network transformation, adjustment and testing are weak. However, the existing experimental model of tunnel network ventilation on double roads mainly adopts the method of similar simulation experiments to study the influence of different tunnel layo...
