Demist principle: overflow the gas that contains moisture from absorption liquid and enter discharge chamber a, enter after dust-removal and desulfurizing is bathed in over-blowing that residual moisture generally is no more than 100mg/m in the flue gas of discharge chamber a through escape pipe 2
3Impeller clearance by demister 3 among the discharge chamber a, be compelled to change direction, drop is separated from the gas under the effect of inertia, centrifugal force, bump, gravity, drop on the blade of demister 3, droplet in the blade falls outflow after gathering together and merging, and the gas after the processing is discharged from escape pipe 4.
According to the description of above the utility model structure as can be known, the utlity model has following advantage:
1, ash-laden gas is by after spraying air inlet pipe 6 and entering absorption liquid in the absorption chamber c, and dust granule is separated from air-flow under effect of inertia, downward precipitation then, and dust removing effects is very good.
2, absorption liquid adopts the closed cycle design, and no waste liquid is discharged, non-secondary pollution.
3, the desulfurization of flue gas and dedusting were all finished before flue gas enters air-introduced machine, and flue gas just enters air-introduced machine after demister further separates, make air-introduced machine be in optimum operation technology, can not be with water, dust stratification, vibration.
4, gas-liquid contact is abundant, dust-removal and desulfurizing efficient height.
5, dust-removing desulfurating apparatus inside can not produce fouling and clogging.
6, adopt lime desulfurization, operating cost is low, and desulfuration efficiency is not influenced by boiler/kiln load.
