Problems solved by technology
[0004] (1) The corresponding data can only be obtained through the pressure or temperature sensor, and the subsequent analysis of the value; the simulation effect diagram of the gas explosion cannot be directly observed
[0005] (2) The gas distribution process of the existing device is cumbersome. When multiple gases are mixed, the gas source needs to be replaced several times for gas distribution, and the gas distribution error is relatively large
[0006] (3) The structure of the device is single, and the data collection is mainly based on a single collection of overpressure, temperature, and flame, and joint collection is rare and no noise collection is seen
[0007] (4) The existing device cannot analyze the residual gas components in the explosion container after the gas explosion
[0008] (5) The volume of the device is too large, the operation is complicated, a large amount of experimental gas or other materials are wasted, and the risk is relatively high

The invention relates to a modern teaching device for simulating the effect of gas explosion and its control method, wherein the device comprises: an explosion reaction container, an inert gas storage bottle, a methane gas storage bottle and a vacuum pump communicated with the explosion reaction container through a valve; The teaching device also includes an ignition controller, an ignition electrode, a plurality of sensors, a data acquisition module and a simulation effect display screen; The external ignition controller is connected; the plurality of sensors are connected to the inside of the explosion reaction vessel, and are connected with the data acquisition module and the simulation effect display screen outside the explosion reaction vessel, for sending the collected data to the data acquisition module and displaying it in the simulation on the effect display. The present invention utilizes the way of vacuuming to extract the air in the explosion reaction container, and then quickly prepares the gas concentration of the gas explosion reaction according to the set gas concentration.
Description
technical field [0001] The invention relates to the field of gas disaster prevention and utilization, in particular to a modern teaching device for simulating gas explosion effects and a control method thereof. Background technique [0002] The existing experimental demonstration device for simulating a gas or gas-coal dust explosion in an underground coal mine tunnel satisfies the demand for an experimental demonstration device for simulating a gas or gas-coal dust explosion in an underground coal mine tunnel. Inject methane gas and coal dust into the explosion chamber. When the pressure in the explosion chamber is equal to the external atmospheric pressure, the high-energy ignition cabinet controls the ignition electrode on the explosion chamber to ignite, so as to realize the explosion experiment of gas and gas-coal dust. The gas after the explosion diffuses out through the gas explosion diffusion pipeline and the gas explosion diffusion branch. The pressure sensor and f...
