Flue gas denitrification equipment

The utility model relates to an environmental protection field discloses a flue gas denitrification equipment, and wherein, this flue gas denitrification equipment includes flue gas denitration flue (4) and sets up bombard formula soot blower (1), sound wave soot blower (2) and steam soot blowing device (3) on flue gas denitration flue (4). Flue gas denitrification equipment makes the deposition of the dustproof sieve netlist face of catalyst aspect obviously reduce, and denitration catalyst surface does not have the deposition, increases the active reaction area of catalyst, reduces the coal ash to the poisoning effect of catalyst, the life -span of extension catalyst, improve denitration efficiency, and guaranteed NOx emission compliance. 本实用新型涉及环保领域，公开了种烟气脱硝设备，其中，该烟气脱硝设备包括烟气脱硝烟道(4)以及设置在所述烟气脱硝烟道(4)上的炮轰式吹灰装置(1)、声波吹灰装置(2)和蒸汽吹灰装置(3)。本实用新型所述烟气脱硝设备使催化剂层面防尘筛网表面的积灰明显减少，脱硝催化剂表面无积灰，增加催化剂的活性反应面积，降低煤灰对催化剂的毒害作用，延长催化剂的寿命，提高脱硝效率，保证了NO排放达标。
