Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment devices, in particular to a waste gas treatment device which is easy to replace. Background Art

[0002] Waste gas treatment devices are environmental protection equipment, mainly used to protect the environment and purify the air by recycling or removing and reducing harmful components in industrial waste gas. These devices usually include different process technologies, such as gas discharge, photocatalysis and biological purification. Filters need to be installed at the discharge port of the waste gas treatment device. The function of the filter is to capture solid particles and other suspended matter in the waste gas;

[0003] As time goes by, the filter will become clogged and worn, and needs to be replaced regularly to maintain the efficiency of the system. However, the filters of some exhaust gas treatment devices currently on the market are fixedly connected to one side of the discharge port, often using bolts or welding connections. When the filter needs to be replaced, the operation is inconvenient, which wastes a lot of manpower and material resources, resulting in long equipment downtime and affecting production efficiency. For this reason, an exhaust gas treatment device that is easy to replace is proposed. Utility Model Content
