Description

Technical Field

[0001] The utility model relates to a flue gas filtering grid frame for purifying and recovering industrial waste gas, belonging to the technical field of waste gas recovery. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes in the factory area of ​​an enterprise. These waste gases include carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, lead and mercury sulfate, beryllium, smoke and production dust. When discharged into the atmosphere, it will pollute the air. These substances enter the human body through the respiratory tract through different pathways. Some of them directly cause harm, while others have an accumulation effect, which will more seriously endanger human health. Different substances will have different effects.

[0003] The existing publication number is CN219764818U, which is a flue gas filter frame for purifying and recovering industrial waste gas. The filter frame is composed of a central axis, a filter plate and fan blades. When air passes through the fan blades, the fan blades can be driven to rotate, and side plates fixedly connected to the central axis are arranged on both sides of the filter plate. Therefore, when filtering the industrial exhaust flue gas, when the flue gas flows through the filter box, the fan blades will be driven to rotate, and then the fan blades will drive the central axis to rotate, and then the two side plates will rotate with the central axis. The bristles on the two side plates can brush the filter plate to clean the dust attached to the surface of the filter plate to prevent the filter plate from being blocked, which is beneficial to the stability of the filter plate. However, industrial waste gas is not a very warm gas or a clean gas, so the bristles are easily corroded after the gas enters, which makes the device have high limitations when used.
