Operation principle of the present utility model is as follows:

Dust-cleaning principle: the flue gas that contains sulfur dioxide enters in the inlet plenum b by air inlet pipe 1, be arranged under the suction function of cylindrical shell 8 outer air-introduced machines (not shown), flue gas enters absorption chamber c from spraying air inlet pipe 6 injections, flue gas is 8m/s in the speed of spraying air inlet pipe 6 spout places, after flue gas injection enters absorption liquid inside, through the liquid level of absorption liquid processing and effusion absorption liquid, the rate of climb is 2m/s.Dust granule dissolves in the absorption liquid among the absorption chamber c in this process, and post precipitation is pulled out by dragging for mud machine 7.Its pressure loss was 400~700Pa after flue gas absorbed through the absorption liquid among the absorption chamber c, and efficiency of dust collection is more than 95%.

Desulfurization principle: the flue gas of dust-laden and sulfur dioxide enters in the inlet plenum b, spray the absorption liquid that enters into absorption chamber c through spraying air inlet pipe 6, form a very big bubbling area and produce bubble, these bubbles promptly constantly generate in a large number and break, constantly produce new contact-making surface, sulfur in smoke is delivered to further in the reaction zone of absorption liquid, fresh absorption liquid is contacted with flue gas.The pH value of reaction zone is controlled between 4.5~5.2, because the rate of dissolution and the pH value of lime stone are exponential relationship, lime stone can quick and completely dissolve, substantially do not have the solid limestone particle in the absorption liquid, the utilization rate of lime stone is 98~100%, in addition, because hydrogen ion and ion concentration of inferior sulfate radical increase, oxidation rate also increases greatly, and sulfur in smoke and calcium hydroxide generation chemical reaction generate calcium sulfite the most at last, reach the desulfurization purpose.

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.
