Such a device is usually designed to be safe enough to conduct demonstrations in a controlled environment, and at the same time, it can clearly illustrate the basic principle of dust explosion.

[0003] After retrieval, the text of the publication number "CN209560835U" mentions that "the utility model discloses a dust explosion demonstration device, including a battery, a high-voltage generating device powered by the battery, and a switch for connecting and disconnecting the battery and the high-voltage generating device. There is a bottom plate on one side of the battery. An arc generating head is provided on the bottom plate. An isolation cover covering the arc generating head is provided on the bottom plate. Air holes are provided on the bottom plate in the area covered by the isolation cover. A connecting body with an air cavity inside and communicating with the air holes is provided below the bottom plate. An air inlet pipe is communicated with the connecting body. A filter screen that blocks dust and allows air to pass through is covered on the air holes. The arc generating head is electrically connected to the output end of the high-voltage generating device. The utility model has the following advantages and effects: The utility model can realize the demonstration of the principle of dust explosion and has high safety performance, enabling students to more intuitively and vividly understand the teaching content of dust explosion. However, when in use, although it can realize the demonstration of the principle of dust explosion and has high safety performance, enabling students to more intuitively and vividly understand the teaching content of dust explosion, this device lacks an effective pressure relief device. During the dust explosion experiment, it is unable to timely release the accumulated excess pressure inside. In this case, the huge pressure difference inside and outside the device will cause the outer shell to bear extremely high stress, exceeding the design limit, thereby causing structural rupture or explosion of the device, which will not only damage the device itself, but also pose a serious threat to the surrounding environment and personnel. And this device cannot be remotely controlled, which leads to the operator having to operate near the physical location of the device, increasing the risk for the operator.

[0028] Furthermore, the driving component 33 includes a storage battery 331 and an ignition signal generator 332. The storage battery 331 is installed inside the base 1, and the ignition signal generator 332 is arranged outside the storage battery 331.
