Pressurized drainage type electrolysis instrument

Abstract

The utility model discloses a pressurized drainage type electrolysis instrument which comprises a base, a liquid storage tank is arranged on the base, a first decomposition pipe and a second decomposition pipe are arranged on the base, a conducting pipe is arranged in the base, and the liquid storage tank is communicated with the first decomposition pipe and the second decomposition pipe through the conducting pipe. A first power connection column and a second power connection column are arranged on the rear side of the base, the liquid storage tank is used for containing electrolyte, the first power connection column and the second power connection column are used for providing power for an external power supply so as to provide energy to enable liquid to be subjected to decomposition reaction, and the first decomposition pipe and the second decomposition pipe are used for collecting substances subjected to the decomposition reaction. After gas is generated through pressurization and decomposition, the liquid level changes, students are helped to understand the relation between air pressure and drainage, liquid adding of the liquid storage tank is closed, the highest scale of the liquid level is marked, the gas generated through decomposition is prevented from pressing electrolyte solution to overflow, and two-stage gas is prevented from being mixed in a conduction pipe due to too much generated gas; the device has the advantage that the two decomposition pipes can be used for exhausting air completely through a drainage method at the same time.
