The air inlet 2 controls micro-positive pressure by intake valve 3, and pressure is 5~10pa；6 pressure of atomizer and
Flow is controllable, and respectively sets an atomizer 6 inside cylinder 1 up and down and form double-layer liquid sealing；The observation window 7 designs for square hole,
And observation window 7 is made of pyroceram；The porous masses 8 are detachable porous masses, are convenient to clean；The cylinder
1 bottom is designed as inverted-cone drainage plate 9, and easy to liquid reflux blowdown after spraying, and inverted-cone drainage plate 9 sets to be detachable
Put, cleaned easy to later stage inner-walls of duct and board slot giant.
Tail gas in kiln roasting process is connected by the utility model by air inlet 2 with apparatus system, passes through air inlet
Valve controlling keeps system 5~10pa micro-positive pressures.Gas enters cylinder 1 and forms diffusion, is flowed up by 5 pressure of air-introduced machine,
