[0002] The production process of composite zinc oxide will produce smoke and exhaust gas emissions, which may contain harmful substances and cause environmental pollution. The use of smoke recovery devices can effectively reduce smoke emissions and comply with environmental protection regulations and standards. However, by installing filters in the recovery device, solid particles and most fine particles can be effectively intercepted to prevent them from being discharged into the atmosphere with smoke and causing air pollution.

[0003] The conventional smoke recovery device for composite zinc oxide production uses bolts to install the filter at the smoke discharge port or exhaust port;

[0004] The traditional smoke recovery device for composite zinc oxide production has the following problems: since the bolt connection method is easily affected by factors such as vibration and temperature changes, the filter may be installed loosely and there is a risk of falling off. In addition, tools are required to tighten or loosen the bolts, which is not conducive to quick maintenance or replacement of the filter. For this reason, we propose a smoke recovery device for composite zinc oxide production. Utility Model Content
