Embodiment Construction

[0019] figure 1 Among them, along the direction of flue gas flow, a modified fly ash injection device (1) is installed in the front section of the inlet flue (2), an air flow distribution device (3) is installed in the rear section of the inlet flue (2), and the inlet flue (2) It is connected with the turbulence enhanced agglomeration device (4), and the turbulent flow enhanced agglomeration device (4) is connected with the dust removal device (6) through the outlet flue (5).

[0020] When the device and method of the present invention are in working condition, the modified fly ash injection device (1) installed in the front section of the inlet flue (2) injects modified fly ash into the flue gas according to the designed injection amount, and the modified fly ash is modified. After the non-toxic fly ash is sprayed into the inlet flue, its rich ultrafine micropores, carbon adsorption sites, metal oxide catalytic sites, etc. have a strong impact on the ultrafine particles and h...

Abstract

The invention relates to a device and a method for efficient adsorption and agglomeration removal of ultrafine particles and heavy metal mercury. By adopting physicochemical and catalytic adsorption,turbulence enhanced agglomeration and other mechanisms, pollutants such as ultrafine particles and heavy metals, including PM2.5 and aerosol, discharged by industrial flue gas are efficiently adsorbed, agglomerated and removed. By adopting the structural form that a modified fly ash spraying device, an airflow distribution device, a turbulence enhanced agglomeration device and a dust removal device are sequentially arranged in the airflow direction, the invention provides the device and method for efficient adsorption and agglomeration removal of pollutants in industrial flue gas of fire coal,fuel oil, waste incineration and the like, wherein the device and method are high in removal efficiency, low in operation cost, and convenient to overhaul, operate and maintain.

Description

technical field [0001] The invention relates to a device and method for efficient adsorption and agglomeration removal of ultrafine particles and heavy metal mercury, in particular to a high-efficiency device consisting of a modified fly ash injection device, an air distribution device, a turbulent flow enhanced agglomeration device, and a dust removal device. Device and method for adsorption and agglomeration removal. Background technique [0002] With the improvement of the new concept and construction level of my country's ecological civilization, my country's pollution prevention and control has entered a critical stage, among which the emission control of ultrafine particles including PM2. It has become the focus and difficulty of air pollution prevention and control. [0003] At present, my country's control technology and technology for industrial flue gas pollutants including PM2.5 and aerosols and heavy metals are still in the initial stage of research and developme...
