Description

Exhaust gas recovery device of lithium battery diaphragm coating machine Technical Field The utility model relates to the technical field of lithium battery manufacturing, in particular to an exhaust gas recovery device of a lithium battery diaphragm coating machine. Background In the process of coating the lithium battery diaphragm, waste gas mainly comes from solvent volatilization, chemical reaction and temperature change in a coating material, common waste gas components comprise organic solvents, volatile organic compounds and chemical substances with stronger smell, and the waste gas has irritation and pollution and must be treated by effective waste gas treatment measures, common waste gas treatment methods comprise an adsorption method, a catalytic combustion method and the like, the adsorption method usually uses adsorption materials such as active carbon and the like, harmful gases are removed by physical adsorption, and the catalytic combustion method is to utilize a catalyst under a high temperature condition to oxidatively decompose the organic waste gas into harmless carbon dioxide and water. Can produce certain waste gas need handle when lithium cell diaphragm coating, current treatment facility only is equipped with a pipeline when absorbing waste gas, through pipeline transmission waste gas, filter through the active carbon layer, but active carbon work has the absorption saturation after a period, needs to be changed, and single pipeline needs to stop production, waits to change the back and resumes production, has improved the time of production, has reduced production efficiency, consequently needs lithium cell diaphragm coating machine waste gas recovery unit to satisfy people's demand.
