Embodiment Construction
[0015] The method and device of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0016] see figure 1 , a device for joint removal of boiler flue gas particles and heavy metals, along the direction of flue gas flow, in a hollow shell (1), there are successively provided with electric dust removal areas (2), fixed beds of mercury catalytic oxidizers ( 3), the adsorbent injection system (4) and the bag type dust removal area (5); the dust hopper (6) is arranged under the electrostatic precipitator area and the bag type dust removal area. A smoke inlet (7) is arranged on one side of the casing, and a smoke outlet (8) is arranged on the other side of the casing.
[0017] The high-concentration flue gas of the coal-fired boiler first passes through the electrostatic precipitator area (2) for dust removal and filtration to remove most of the particulate matter and some particulate heavy metals, and collects the fly ash particle...
