Abstract Innovation of scientific instruments is of great significance. Combination method is a common method of innovation. With the main body addition method as the main method and the other combination method as the supplement, and taking the electrolytic saturated experimental water device in textbooks and the chlorine hydrogen combustion device in exercises as the main body, the simple Kaipu generator device, the anti-backdraft device of hydrogen chloride tail gas and the hydrogen soap bubble combustion test method as the additional parts are organically combined, a new demonstration device for industrial preparation of hydrochloric acid was designed. The application steps of combinatorial method in innovation of chemical instruments are summarized, which is beneficial to popularization and application.
