This invention provides a synergistic purification system and method for ammonia-based desulfurization based on source control and process enhancement, belonging to the field of flue gas pollution control technology. It constructs a closed-loop control system covering the entire process, providing a synergistic purification solution for ammonia-based desulfurization encompassing "source monitoring and control—process impurity removal—end-of-pipe gradient purification—intelligent emergency response." This solution can handle complex flue gas compositions, ultimately achieving a stable total emission concentration of condensable particulate matter (CPM) and filterable particulate matter (FPM) in the flue gas to meet ultra-low emission standards (e.g., ≤5 mg / m³). 3 This invention is particularly applicable to industrial scenarios that generate complex sulfur-containing flue gas, such as coal combustion, hazardous waste incineration, and chemical tail gas co-firing, and aims to achieve synergistic deep removal of sulfur dioxide (SO2) and condensable particulate matter (CPM).

This invention relates to the field of construction waste recycling technology, specifically to a multi-stage anti-clogging vibrating screen for asphalt pavement milling materials. The screen includes a screen box containing a first screening component, a limiting component, and a clearing mechanism. The first screening component includes multiple cantilever screen bars. The limiting component includes a limiting plate with multiple limiting grooves. A clearing mechanism is located beside the limiting component, comprising a drive component and rake teeth. An air outlet is located beside the clearing mechanism. The rake teeth insert into the gaps between the multiple cantilever screen bars to break the mechanical jamming of the material. Simultaneously, the directional airflow from the air outlet continuously cools the core area of ​​frictional heat generation between the rake teeth and the limiting grooves, strictly controlling the contact surface temperature below the asphalt softening point. This physical breaking combined with temperature control fundamentally eliminates the problem of screen clogging caused by asphalt melting and stringing due to frictional heat.
