Summary of the invention
Technical problem: in order to overcome the problem that existing design exists, the invention provides a kind of integrated smoke desulfurizer of smoothing absorbing tower, the compact conformation of this desulfurizer can reduce cost and operating cost significantly.
Technical scheme: the present invention be contour with the flue gas homonymy that has the anti-return gas approach, has a flow field adaptive faculty, put down the flat flow absorption tower of into clearing and substitute the core apparatus of spray column as flue gas desulphurization system, this device is made up of flue, former gas baffle door, flue gas radiator, flat flow absorption tower, demister, flue gas heat dump, clean gas baffle door, by-pass damper door; Wherein, be provided with a by-pass damper door in the centre of flue, flue be divided into flue inlet side and flue go out end, be connected with former gas baffle door in the inlet side of flue and be connected with the flat flow absorption tower by the flue gas radiator; The end that goes out on flat flow absorption tower passes through the inlet side that the flue gas heat dump connects demister, and the end that goes out of demister goes out end by the flue that clean gas baffle door connects flue.
Uptake zone, flat flow absorption tower is horizontal U type, flue gas is realized the break-in of U type in tower, the smoke entrance on absorption tower is in the same side of tower, and the gas approach on flat flow absorption tower and exhanst gas outlet are on sustained height, flue gas does not have perpendicular flow from advancing tower to going out tower, does not have height change.
The flue gas level on flat flow absorption tower is passed through, and its flue gas flow rate is several times as much as spray column.After former flue gas was drawn from boiler back end ductwork, level entered GGH heat release side, almost at the uniform velocity, flatly entered the flat flow absorption tower after the heat release, contact with absorbing the slurries cross-current, after the desulfurization again level pass through the GGH heat absorbing side, enter smoke stack emission after the heat again.The crushing of whole desulphurization system is little than conventional design, and being expected to all provides pressure head by steam generator system, and no longer increases special desulfurization blower fan.
Beneficial effect: the flat flow absorption tower reduces so its height and diameter all have significantly because the absolute altitude of the flue gas flow rate height in the tower, import and export is identical, and equipment manufacturing cost reduces.Because the smoke entrance absolute altitude unanimity of boiler flue, absorption tower and GGH, the major function unit directly connects, and arranges smooth and easy; The contraction in length of flue can be saved lot of materials; The pressure loss is also less, is expected to rely on the pressure head more than needed of steam generator system self to overcome, and does not need to increase special desulfurization blower fan, relatively has simplified equipment, arranges compact characteristics with the WFGD of routine, can reduce cost and operating cost significantly.
