AI Technical Summary

Technical Problem

The existing lithium battery separator production process suffers from the problem of oil fume hoods failing to capture oil fumes, posing a risk of accumulated oil and impurities falling into the air. Furthermore, the exhaust gas treatment equipment in the production workshop is far from the production line, and the pipes are prone to oil accumulation, making cleaning inconvenient.

Method used

Design a fume hood absorption device for a diaphragm production line. The device uses a V-shaped hood combined with strip holes to absorb fumes laterally and from above, and is equipped with an oil collection assembly, including a tapered tube and a recovery plate. By changing the direction and velocity of the fumes, waste oil and impurities can be recovered.

Benefits of technology

It improves flue gas absorption, reduces flue gas overflow and oily impurities falling off, extends pipeline cleaning cycles, and reduces operating costs.

Abstract

This utility model discloses an oil fume hood absorption device for a diaphragm production line, including a hood body with multiple strip-shaped holes, and an oil collection shell detachably connected to the lower end of the hood body. An exhaust pipe is connected to one side of the hood body, and an oil collection assembly for recovering waste oil from the flue gas is connected to the exhaust pipe. The oil collection assembly includes a conical tube connected to the exhaust pipe, with the end of the conical tube away from the exhaust pipe connected to the oil collection shell. In this utility model, by using a V-shaped hood body with strip-shaped holes, the absorption of flue gas from the side and from above can be combined, improving the absorption effect of multiple flue gas and reducing flue gas overflow. Simultaneously, the strip-shaped holes allow flue gas to pass through more easily, and significantly change the flow direction and convergence of flue gas within the hood body, reducing the accumulation of waste oil on the outer wall of the hood body and preventing accumulated oil impurities from falling onto the membrane surface.
