Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing:

[0019] like figure 1 As shown, the flue gas desulfurization device of the present invention includes a housing 1, an air inlet pipe 3, an air outlet pipe 11, an overflow tank 6, an overflow plate 7, a liquid replenishment pipe 5, a rotating partition 8, a buoy 9, a rotating beam 10, an inlet Liquid pipe 16, liquid outlet pipe 17, liquid inlet pipe control valve 18, liquid outlet pipe control valve 19, rotating partition contact 20, overflow plate contact 21, demister 12, fan blade 15, motor 23, control Device 22. Wherein the air intake pipe 3 enters from the upper end of one side of the housing 1, the air intake pipe 3 extends downwards, the air intake pipe outlet 4 at the lower end of the air intake pipe 3 is close to the liquid surface, the absorption liquid is a sodium hydroxide solution, and multiple overflows are arranged above the housing. A launder 6 and a pluralit...

Abstract

The invention relates to a flue gas desulfurization device. The flue gas desulfurization device comprises a casing (1), a gas inlet pipe (3), a gas outlet pipe (11), overflow tanks (6), overflow plates (7), liquid replenishing pipes (5), rotating separating plates (8), buoys (9), rotating beams (10), a liquid inlet pipe (16), a liquid outlet pipe (17), a liquid inlet pipe control valve (18), a liquid outlet pipe control valve (19), rotating separating plate contacts (20), overflow plate contacts (21), a demister (12), fan blades (15), a motor (23) and a controller (22), wherein the rotating separating plates rotate by the aid of buoyancy of an absorption liquid through the buoys at lower parts of the rotating separating plates, so that distances between the rotating separating plates and the overflow plates are adjusted, and the flue gas circulation processing quantity is adjusted; the efficiency of purification of sulfur dioxide in gas can be improved.

Description

technical field [0001] The invention relates to a flue gas desulfurization device. Background technique [0002] When coal-fired boilers are burning, various organic and inorganic sulfur contained in coal are converted into sulfur oxides mainly sulfur dioxide, which enters the atmosphere and combines with water in the atmosphere to form acid rain, which not only affects ground buildings and crops Seriously affect human health, so flue gas desulfurization is an important part of environmental protection. [0003] The main method of flue gas desulfurization is wet desulfurization, which uses limestone and other slurries as detergents to wash the flue gas in the reaction tower to absorb sulfur dioxide in the flue gas. However, the existing flue gas desulfurization devices generally have the problems of complex structure, high manufacturing cost and unsatisfactory desulfurization effect. Contents of the invention [0004] The object of the present invention is to provide a w...
