Specific embodiment
The present invention is further described in explanation and specific embodiment below in conjunction with the accompanying drawings.
A kind of calcination, fluidization stove dust-extraction unit, which is characterized in that including:Grey room 8 and the air inlet being arranged on inside grey room 8 Air duct 7, the both sides inside the wind inlet channel 7 are equipped with multiple symmetrical Whirlwind cyclones 9, and the Whirlwind cyclone 9 positioned at the same side is set In same straight line, 9 side wall of Whirlwind cyclone is equipped with the air inlet communicated with wind inlet channel 7, and 9 lower part of Whirlwind cyclone is equipped with and falls ash Mouthful, the ash port setting weight flap valve 12, each 9 top of Whirlwind cyclone is equipped with air outlet, and the air outlet is equipped with dust-break Plate 13, grey 8 end of room are equipped with ash discharge auger 10, and 10 discharge port of ash discharge auger is equipped with Double-hammer flap valve 11, grey 8 upper end of room It is connect with air compartment 6, multigroup filter bay assembly 5 is equipped in air compartment 6,6 upper end of air compartment connects multiple blowback rooms 4, the blowback room 4 For multicell structure, each 4 absolute construction of blowback room, the side of the multiple blowback room 4 is mounted on a set of pulse valve module 2, 4 top of blowback room is connected with air-purifying chamber 1, and 1 top of air-purifying chamber is equipped with cover board, and promotion is equipped on the cover board Valve module 3,1 side of air-purifying chamber are equipped with gas outlet, and the air-purifying chamber 1, blowback room 4, air compartment 6 are welded for monoblock type steel plate Structure, grey room 8 is with air compartment 6 using flanged joint, and airintake wind-tunnel 7, Whirlwind cyclone 9 are connect with grey room 8 by the way of welding, pulse Valve module 2 is made of pulse valve, pulse tube, and poppet valve assembly 6 is made of lifting cylinder, flashboard, and filter bay assembly 5 is by filter bag and bag Cage forms.
