Problems solved by technology

In junior high school chemistry textbooks, there are contents related to flammable gas explosion and hydrogen explosion. Among them, only hydrogen explosion can complete the hydrogen explosion experiment through the experimental method provided in the textbook, but this hydrogen explosion experiment is difficult and not easy to succeed; for flammability Gas explosions can only be described to students based on the content in the textbooks. There is no relevant experimental demonstration content, so it is difficult for students to understand, and it is impossible for students to deepen their understanding of the hazards of flammable gas explosions from the senses

Abstract

The invention discloses a gas explosion experiment device and relates to the technical field of experiment teaching aid manufacture. The gas explosion experiment device comprises a first container, wherein the first container is placed on a bottom plate, a gas delivery pipe extending into the first container is arranged on the bottom plate, and two first detonating fuses which are respectively connected with the high-voltage signal pulse output end and the ground wire end of a pulse ignition device are arranged at the lower part of the first container; a second container is fixedly arranged on the bottom plate and on one side of the first container, and a cover body is movably arranged at the top of the second container; second detonating fuses which are respectively connected with the high-voltage signal pulse output end and the ground wire end of the pulse ignition device are arranged at the lower part of the second container. Compared with the prior art, the gas explosion experiment device can safely and conveniently carry out combustible gas explosion and hydrogen explosion demonstration.

Description

technical field [0001] The invention relates to the technical field of manufacturing experimental teaching aids, in particular to an apparatus for gas explosion experiments. Background technique [0002] Experimental teaching is an important part of chemistry teaching. It can stimulate students' interest in learning chemistry, help students form chemical concepts, and acquire chemical knowledge and experimental skills. In junior high school chemistry textbooks, there are contents related to flammable gas explosion and hydrogen explosion. Among them, only hydrogen explosion can complete the hydrogen explosion experiment through the experimental method provided in the textbook, but this hydrogen explosion experiment is difficult and not easy to succeed; for flammability Gas explosions can only be described to students based on the content in the textbooks. There is no relevant experimental demonstration content, which is difficult for students to understand, and it is impossib...
