AI Technical Summary

Technical Problem

In existing injection molding machine exhaust gas treatment devices, the contact angle between the exhaust gas and the UV photolysis lamp is insufficient, resulting in incomplete photocatalytic oxidation purification and the easy discharge of residual exhaust gas.

Method used

Design an integrated treatment device for injection molding machine exhaust gas, including a U-shaped treatment housing. The housing has an arc-shaped purification section in the middle and multiple photocatalytic oxidation mechanisms inside. The photocatalytic oxidation mechanism consists of an outer frame and UV photolysis lamps, and the lamps have an adjustable tilt angle. The arc-shaped structure extends the purification space, and the device can be easily installed through a snap-fit ​​groove.

Benefits of technology

This technology enables multi-angle contact between exhaust gas and UV photolysis lamps, improving the thoroughness and stability of photocatalytic oxidation purification and ensuring efficient completion of exhaust gas treatment.

Abstract

This utility model discloses an integrated treatment device for injection molding machine exhaust gas, including a treatment housing with an arc-shaped purification section in the middle. The treatment housing and the arc-shaped purification section are integrally arranged in a U-shape. Multiple photocatalytic oxidation mechanisms are provided inside the arc-shaped purification section. A first adsorption filter seat and a second adsorption filter seat are also provided at one end of the treatment housing. An air inlet is provided on one side of the first adsorption filter seat, and an exhaust port is provided on one side of the second adsorption filter seat. This utility model extends the photocatalytic oxidation purification space by providing an arc-shaped purification section in the middle of the treatment housing, and multiple photocatalytic oxidation mechanisms with different inclination angles are provided inside the arc-shaped purification section, which is beneficial to improving the thoroughness of photocatalytic oxidation purification of exhaust gas. Moreover, by setting multiple photocatalytic oxidation mechanisms with different inclination angles, multi-angle contact between exhaust gas and UV photolysis lamps can be achieved, further improving the thoroughness of photocatalytic oxidation purification of exhaust gas.
