Aluminum air battery electrolyte circulating system based on hydrocyclone effect

Abstract

The invention discloses an aluminum air battery electrolyte circulating system based on a hydrocyclone effect. The aluminum air battery electrolyte circulating system comprises an aluminum air battery pack, an electrolyte storage barrel, a diaphragm pump and a precipitate collection device, wherein the upper part of the electrolyte storage barrel is connected with an inlet of the diaphragm pump through a pipeline; the precipitate collection device consists of a hydrocyclone and a precipitate collection box; a liquid inlet of the hydrocyclone is connected with an outlet of the diaphragm pump through a liquid acceleration pipe; a liquid outlet in the top of the hydrocyclone is connected with a liquid inlet of the aluminum air battery pack through a pipeline; a liquid outlet of the aluminum air battery pack is connected with the electrolyte storage barrel through a pipeline; a liquid outlet in the bottom of the hydrocyclone is connected with the precipitate collection box through an underflow pipe of the hydrocyclone; the upper part of the precipitate collection box is connected with the pipeline between the electrolyte storage barrel and the diaphragm pump through a branch; a check valve and a pipeline valve are arranged on the branch. The system is simple in design structure, low in energy consumption and convenient to maintain, and the use amount of electrolyte in the aluminum air battery pack is greatly reduced.

Description

technical field [0001] The invention relates to an electrolyte circulation system of an aluminum-air battery, in particular to an electrolyte circulation system of an aluminum-air battery based on hydrocyclone. Background technique [0002] Aluminum-air fuel cells use oxygen in the air as the positive electrode active material, use high-purity aluminum or aluminum alloy with high energy density as the negative electrode of the battery, and use KOH and NaOH as the electrolyte to convert a large amount of chemical energy contained in metal aluminum become electricity. Compared with other current chemical power sources, aluminum-air batteries have the following unique advantages: First, the specific energy is high, and its specific energy can theoretically reach 8718 Wh / kg, and currently it can reach 300-400 Wh / kg, which is much higher than other batteries. Various batteries. Second, the aluminum-air battery has a very stable discharge voltage and high instantaneous output po...
