Abstract
The invention relates to a processing system and method for waste gas containing sticky dust. The processing system for the waste gas comprises a pre-powder-injection device, bag-type dust removal equipment and intelligent control equipment, wherein a material outlet of the pre-powder-injection device and an inlet of the bag-type dust removal equipment are arranged on a waste gas pipeline in sequence along an airflow direction of the waste gas; the bag-type dust removal equipment is provided with a plurality of dust removal unit boxes working independently, wherein each dust removal unit box has three working modes: adding powder to an outer surface of the dust removal bag, removing dust through filtration by the dust removal bag and cleaning a surface by the dust removal bag; the intelligent control equipment is used for controlling the plurality of dust removal unit boxes to work in sequence; and each dust removal unit box is circularly switched to work under the three working modes,and when at least one dust removal unit box is under the working mode of removing dust through filtration by the dust removal bag, the pre-powder-injection device is opened. According to a technologycombining pre-powder-injection with bag-type powder coating, the technical problems in the prior art that the sticky dust of the waste gas is adhered to the surface of a filtering material to block the filtering material and cannot be cleaned are solved; meanwhile, a sticky dust removal rate in the waste gas is guaranteed to be greater than or equal to 90%; the technology is intensified; and operation cost is low.
Description
technical field [0001] The invention relates to the technical field of environmental protection engineering, in particular to a waste gas treatment system and treatment method containing sticky dust. Background technique [0002] With the development of the economy, industrial production has increased significantly, resulting in a large amount of industrial waste gas emissions, which has degraded the quality of the atmospheric environment. This year, smog weather occurs frequently, causing serious harm to human health and causing huge losses to the national economy. Dust pollution accounts for a large proportion of air pollution. Although large-scale pollution sources have been effectively controlled, such as thermal power plants, cement building materials and other industries have completed the ultra-low emission requirements this year, the pollution emissions of a large number of small and medium-sized enterprises Still need to improve. In areas where the hardware manufa...
