Definitions
- the present invention reduces components and substances contained in sulfur oxides (hereinafter sometimes referred to as SOx) in exhaust gas, dust and boiler fuel using an absorbent containing limestone or a slurry containing lime.
- SOx sulfur oxides
- the longitudinal direction is horizontally directed from the outlet of the circulation pump (not shown) through the absorbent circulation pipe 11 and sufficient for each spray header 3.
- the diameter of the spray header 3 usually needs to be lm or more to supply the absorbing solution. Therefore, when installing multiple stages of spray headers 3 in the height direction of the vertical absorption tower 1, the height of the spray header installation part is relatively high in order to properly secure the gap between the two adjacent spray headers 3 and 3. As a result, the overall height of the absorption tower 1 also increases, and the cost of the absorption tower 1 increases.
- the installation height of the spray header 3 in multiple stages is increased, the head of the absorber circulation pump 12 is increased, and the power consumption of the pump 12 is increased as compared to the prior art.
- the spray header 3 with a large diameter is installed around the absorption tower 1, there also arises a problem that it becomes difficult to arrange the sidewalk for maintenance.
- a spray nozzle of a spray header which introduces an exhaust gas discharged from the combustion apparatus and which is provided with a plurality of absorbents containing a slurry containing limestone or stone ash in the exhaust gas flow direction. And an absorber for absorbing and removing substances derived from dust, sulfur oxides and components contained in fuel used in the combustion apparatus if it is contained in the exhaust gas, and an absorbing liquid provided in the lower part of the absorber.
- a wet flue gas desulfurization apparatus comprising a reservoir and a plurality of absorbent circulation channels for circulating and supplying the absorbent which is extracted from the absorbent reservoir to the outside of the absorption tower again to the spray headers.
- each spray header For each spray header, it enters the absorption tower from the wall of the empty tower near the absorption liquid reservoir, and its longitudinal direction is arranged in the direction along the exhaust gas flow at the center of the absorber or near that.Tip is a wet flue gas desulfurization apparatus comprising structure mosquito ⁇ et connected to spray header.
- the invention according to claim 2 is the wet type flue gas desulfurization according to claim 1, wherein a plurality of spray nozzles of each spray header are arranged concentrically in a plane orthogonal to the exhaust gas flow direction in the absorption tower. It is an apparatus.
- the invention according to claim 3 is the wet flue gas desulfurization apparatus according to claim 1, wherein a plurality of spray nozzles of each spray header are disposed in a straight line in a plane orthogonal to the exhaust gas flow direction in the absorption tower. .
- each absorbent circulation pipe 11 provided with each absorption tower circulation pump 12 corresponding to each spray header 3 provided in a plurality of stages in the exhaust gas flow direction is the absorption tower 1 It penetrates the wall and is inserted inside the absorption tower, and vertically rises from the central portion near the liquid surface of the liquid reservoir 9 of the absorption tower 1 and is connected to the spray header 3.
- a part of the absorption liquid circulation pipe 11 which penetrates the wall of the absorption tower 1 and is inserted into the interior and reaches almost the central part of the absorption tower 1 is inclined piping power and connected to the spray header 3 from almost the central part of the absorption tower 1 It is preferable to have the configuration launched vertically.
- the central portion of the absorption tower 1 The absorbent circulation pipe 11 extending vertically upward is connected to the spray header 3a disposed in the horizontal direction.
- the spray header 3a shown in FIG. 1 has a cross shape in plan view, and a plurality of circular shapes having concentric planes with a horizontal direction centering on the absorbent circulation pipe 11 at the center of the absorption tower 1 in the cross shape spray header 3a.
- Type of spray header Connect multiple 3b.
- Absorbent tower 1 Absorbent slurry velocity near wall surface decreases. Therefore, the amount of spray liquid in the spray nozzle 5 near the absorption liquid circulation pipe 11 in the central part of the absorption tower 1 causes an imbalance such that the amount of spray liquid in the vicinity of the wall surface decreases, and desulfurization performance is satisfied. Not good for
- the internal flow velocity of the cruciform spray header 3a can be set so that it can be maintained substantially constant at all parts of the header 3a. Change the pipe diameter depending on the part.
- the present invention is effective for a plant capable of treating a large volume of exhaust gas and requiring high-efficiency desulfurization of an exhaust gas having a high SOx concentration.
- FIG. 1 is a view showing a spray header and a spray nozzle arrangement of a wet desulfurization apparatus for treating an exhaust gas having a high SOx concentration according to the present invention, in which the spray nozzles are arranged concentrically.
- FIG. 2 is a view showing the arrangement of spray headers and spray nozzles of the wet desulfurization apparatus for treating exhaust gas of high SOx concentration according to the present invention, in which the spray nozzles are arranged in a linear shape.
- FIG. 3 is a diagram showing a system around an absorption tower of a wet flue gas desulfurization apparatus for treating exhaust gas with high SOx concentration of the present invention.
