Abstract

The invention relates to the technical field of battery production, and provides a drying oven fresh air system which comprises a drying oven. The separation device is provided with a gas inlet, a first outlet and a second outlet, the gas inlet is communicated with the inner space of the drying oven, the separation device is arranged to separate gas entering the separation device into first gas and second gas, and the density of the first gas is larger than that of the second gas; the first outlet and the second outlet are used for discharging the first gas and the second gas from the separating device respectively, the first outlet is communicated with the external space of the drying oven, and the second outlet is communicated with the internal space of the drying oven. Through the arrangement, separation and discharge of the solvent gas are achieved, the content of the solvent gas in the drying oven is reduced, recycling of high-temperature gas and heat of the high-temperature gas is achieved, energy needed for maintaining the temperature in the drying oven is reduced, and energy is saved. The problem of energy loss when the content of harmful gas in the drying oven is reduced in the prior art is solved.

Description

Technical field [0001] The invention involves the field of battery production technology and especially involves a fresh air system. Background technique [0002] During the production of lithium batteries, the raw material slurry needs to be coated on the foil to form a polar sheet, and then dried to make the pole volatilize the solvent in the oven to form a dry pole. During the drying process, harmful gases such as solvent gas will accumulate inside the oven. The solvent gas is flammable. In order to reduce the concentration of the solvent gas inside the oven, the gas in the oven needs to be discharged. However, while discharging solvent gas, the high -temperature gas in the oven will also be discharged together, causing energy loss. [0003] Therefore, how to solve the problem of energy loss in the existing technology when reducing the content of harmful gases in the oven has become an important technical problem to solve the technical personnel in the art. Invention content ...
