Description

Technical Field

[0001] The utility model relates to the field of industrial waste gas treatment, in particular to a novel high-efficiency industrial waste gas treatment device. Background Art

[0002] We are currently in an industrialized society, and a large amount of industrial waste gas is generated during industrial production in factories. Industrial waste gas contains components such as large particles, fine dust and harmful gases. The above substances are discharged into the atmosphere, which will damage human health and the human living environment. Therefore, industrial waste gas usually needs to be disposed of through a waste gas treatment system. The current industrial waste gas treatment devices have the following problems: First, the amount of harmful substances in industrial waste gas is not uniform, and has a peak characteristic. In order to meet the peak treatment needs, the industrial waste gas treatment device usually passes the industrial waste gas slowly through the treatment device, so the treatment speed is slow and the efficiency is low. It also requires huge equipment, a large footprint, and high fixed investment. Second, the current industrial waste gas treatment system does not handle large particles, fine dust, and film materials well. If these substances enter the subsequent process sections, they will clog the equipment and further reduce the treatment efficiency. Third, some factories select treatment equipment based on the lowest harmful gas concentration, resulting in the sneak discharge of harmful gases at peak times, polluting the environment.
