Problems solved by technology

[0004] Although the test can be carried out on coal piles, the spontaneous combustion of coal piles is random, and it is not easy to quickly form spontaneous combustion of coal piles in a natural state. In addition, it is difficult to quantify the effect of inhibitors

Embodiment 1

[0035] This embodiment provides a test device for the effect of inhibitors, including an observation device, an ignition device, a barrier device and an inhibitor storage device; the observation device includes a body 10, the inside of which is provided with a cavity, and the top is provided with a The opening through the cavity, the bottom is provided with an air pump hole connected with the cavity, the body 10 has an observation area for observing the internal conditions of the cavity; the ignition device includes a heating plate 3, a heating plate 4 and an air pump 5; the heating plate 3 and the heating The plate 4 is set in the cavity of the body 10; the heating plate 3 is a metal plate for placing the coal pile 2; the heating plate 4 is a hollow structure, located below the heating plate 3 and above the air pump hole; the air outlet of the air pump 5 It is connected with the air pump hole; the barrier device includes an electromagnetic pin puller 6, a slider 7, a driving s...

Embodiment 2

[0054] This embodiment provides a test method for testing the effect of a chemical inhibitor, which is carried out by using the above-mentioned test device for testing the effect of a chemical inhibitor, and includes the following steps:

[0055] S1, put the coal pile 2 on the heating plate 3, start the heating plate 4 and the air pump 5;

[0056] S2, when the coal pile 2 reaches the ignition point and spontaneously ignites, immediately remotely supply power to the electromagnetic pin puller 6, and stop the power supply of the heating plate 4 and the inflation of the air pump 5 at the same time, and the output end of the electromagnetic pin puller 6 is retracted after being powered on, and the pairing is released. Constrained by the slider 7, the drive spring 8 in the compressed state drives the slider 7 to move. After the slider 7 moves in place, the inlet of the inhibitor, the connecting hole and the outlet of the inhibitor are connected, and the inhibitor stored in the reage...

Abstract

The invention provides a stopping agent effect test device and method, and belongs to the technical field of coal mine safety, and the device comprises an ignition device, a blocking device, a test device, a stopping agent storage device and an observation device. The ignition device achieves accelerated spontaneous combustion of a coal pile through manual simulation, the blocking device blocks the stopping agent storage device and can remotely drive the blocking device to move in place, constraint on the stopping agent storage device is relieved, the stopping agent flows into the observation device for stopping agent effect testing, and the testing device can remotely monitor the state of the blocking device. And the observation device can be used for observing the internal state change. According to the invention, the spontaneous combustion phenomenon of the coal pile can be rapidly simulated, the inhibition effect of the inhibitor on the coal pile can be effectively tested, the above processes can be remotely controlled, the test safety is ensured, and the test can be observed in the whole process.

Description

technical field [0001] The invention belongs to the technical field of coal mine safety, and specifically discloses an inhibitor effect test device and method. Background technique [0002] In the field of coal mine safety technology, coal spontaneous combustion is an objective phenomenon. Its formation mechanism is mainly that oxygen molecules first form physical and chemical adsorption heat on the surface of coal, causing the temperature of coal to rise slowly. The active functional groups on the surface of molecules undergo deep oxidation and decomposition reactions, and the heat accumulates, which eventually leads to spontaneous combustion of coal. [0003] The most effective way to prevent spontaneous combustion of coal piles is to spray inhibitors. Inhibitors are also called negative catalysts. In the book "Spontaneous Combustion Mechanism and Flame Retardant Technology of Coal Pile in Large Power Stations" edited by Chen Gang, Su Wei, Lin Musong, etc., various types ...
