Multi-gas manufacturing device

Abstract

The invention discloses a multi-gas manufacturing device. The multi-gas manufacturing device comprises a gas generator, wherein the gas generator is provided with a reacting container, a liquid storage container and an auxiliary container. The multi-gas manufacturing device is characterized in that a sealing piston is arranged on the reaction container and communicated with an inlet and outlet, the inlet and outlet is communicated with a guide pipe and a branch pipe, the guide pipe and the branch pipe are connected with a main switch and an auxiliary switch respectively, the main switch is connected with the liquid storage container, and the auxiliary switch is connected with the auxiliary container. The multi-gas manufacturing device is simple in structure, convenient to manufacture, rapid to operate, safe, reliable, environmentally friendly, controllable and convenient to popularize.

Description

technical field [0001] The invention relates to the field of education and teaching, in particular to various gas production devices. Background technique [0002] At present, in middle school chemistry, the device for producing gas from solid and liquid without heating is relatively complicated, with high cost and complicated operation, which reduces the operability of the device, cannot carry out quantitative experiments, waste gas is easy to leak, and the amount of medicine is large. From the start of the reaction until the end of the reaction, the reaction process cannot be controlled at any time, and the experiment cannot be repeated, which is not conducive to the explanation of the experimental phenomenon and the interpretation of the results. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a gas generator with simple structure, convenient use, fast operation, safety, reliability, environmental protection a...
