Abstract

The invention discloses a streamlined surface oxidation air box for removing sulfur, comprising a box body (1), wherein the box body (1) is a hollow flat body of which the surface facing a stirrer (2) is a streamlined outer-convex arch surface capable of reducing erosion wear and the upper surface (11) and the lower surface (12) facing backwards along the fluid flow direction is a streamlined flat plane. The upper wall (13) of the box body (1) is provided with an air inlet hole which communicates with the air outlet of an oxidation air pipe, and the lower wall (15) is provided with multiple air outlet holes (16). After the surface oxidation air box is used, the air bubbles which are formed by discharging the oxidation air are smaller, and the contact reaction area with the fluid flow is larger to be completely used. The surface oxidation air box has better oxidation effect of the fluid in absorption towers and can improve the effect of removing the sulfur. The surface oxidation air box has a simple structure and smaller pushing force of the streamlined surface applied by the stirrer, can reduce the vibration produced by flushing, and can reduce the wear.

Description

Desulfurization is with fairing ace oxidation air case
Technical field
The present invention relates to flue gas desulfur device, be specifically related to a kind of desulfurization and use the oxidation air device.
Background technology
Flue gas desulfurization is called the oxidation air pipe again with the oxidation airduct, and its effect is that oxidation air is transported in the slurries of desulfuration absorbing tower, for slurries provide oxygen, with the SO in the slurries 2, H 2SO 3, SO 3 2-Deng being oxidized to SO 4 2-, and with slurries in Ca 2+Reaction forms CaSO 42H 2O.The oxidation air pipe has various ways; It is the front portion of opening directly being led to the side-feeding mixer blade in the absorption tower that a kind of oxidation air pipe is arranged; Under the promotion of slurry stream; The oxidation air that comes out from the oxidation air pipe is pushed to the back rising of middle part, absorption tower, in this process, accomplishes the oxidation contact.The oxidation air pipe of this structure is because oxidation air is directly to feed through the oxidation air pipe; The bubble that oxidation air forms after coming out from the oxidation air pipe is bigger; Can not be fully used; Thereby cause the slurries oxidation effectiveness in the absorption tower bad, and then influence desulfuration efficiency, cause the lime stone consumption to increase.The percussion that circular oxidation air pipe receives slurry stream is also bigger, is easy to generate vibrations, and it is also bigger to wear and tear.
Summary of the invention
The purpose of this invention is to provide a kind of can make oxidation air from the oxidation air pipe come out bubble that the back forms littler and be fully used, make that slurries oxidation effectiveness in the absorption tower is better, the desulfurization that can improve desulfurized effect is with fairing ace oxidation air case.
Technical solution of the present invention is: it comprises casing; Casing for towards the face of agitator for can reduce convex arc surface outside erosive wear streamlined, along the slurry stream direction backward above and below be the hollow flat body of streamlined flat horizontal surface, the upper wall of casing is provided with the air admission hole, the lower wall that are connected with the oxidation air pipe and is provided with a plurality of ventholes.
Technique effect of the present invention is: the bubble that forms after using its oxidation air to discharge is littler, and is bigger with the haptoreaction specific area of slurry stream, thereby is fully used, and it can make the slurries oxidation effectiveness in the absorption tower better, can improve desulfurized effect.It is simple in structure, and the thrust that fairing ace makes it receive agitator is littler, can reduce the vibrations of being washed away generation, and reduce wear.
Description of drawings
Accompanying drawing is that figure cuts open in the three-dimensional installation of embodiment of the invention office.
The specific embodiment
Shown in accompanying drawing; It comprises casing 1; Casing 1 for towards the face of agitator 2 for can reduce convex arc surface outside erosive wear streamlined, along the slurry stream direction backward above 11 and below 12 be the hollow flat body of streamlined flat horizontal surface, the upper wall 13 of casing 1 is provided with the air admission hole 14, the lower wall 15 that are connected with the oxidation air pipe and is provided with a plurality of ventholes 16.
Casing 1 is parallel with the direction of slurry stream along slurry stream direction structure symmetry, its symmetrical centre face towards the outer convex arc surface of agitator 2.Casing 1 towards the face of agitator 2, above the slurry stream direction 11 and below 12 end faces of both sides be streamlined evagination arcwall face along slurry stream direction structure symmetry.Casing 1 above the slurry stream direction 11 with below 12 along slurry stream direction structure symmetry, its symmetrical centre face is parallel with the direction of slurry stream.Top 11 and following 12 of casing 1 be big perpendicular to the direction length of slurry stream, along the little rectangle of the direction length of slurry stream.Casing 1 is the tip that constitutes, the limit that links to each other by casing upper wall 13 and lower wall 15 seamed edges along the slurry stream direction towards the opposite of the face of agitator 2.Distance between casing upper wall 13 and the lower wall 15 diminishes along the direction of slurry stream from agitator 2 sides gradually; Air admission hole 14 is located on the casing upper wall 13, the maximum position of distance between upper wall 13 and the lower wall 15, and venthole 16 is located on the casing lower wall 15 distance between the upper wall 13 and lower wall 15 along slurry stream direction position from large to small.Set out pore 16 like this and can guarantee that oxidation air flows out along the direction of slurry stream, the perforate vertical with the flow direction can produce negative pressure when the high speed flow is arranged, and can oxidation air directly be taken away.Each venthole 16 is in a row arranged perpendicular to the direction of slurry stream in casing lower wall 15 upper edges, and the venthole 16 of adjacent rows is staggeredly set.The air admission hole 14 of casing 1 is welded to connect with the tube head of oxidation air pipe, and guaranteeing it, streamlined the plane of symmetry is parallel with the slurry stream of agitator 2 up and down.The diameter of venthole 16 is not more than 15mm on the casing 1, and the bubble diameter that can guarantee to come out from casing is less than 15mm.
The present invention has following advantage: 1, its oxidation air venthole 16 the gross area be 1.5 times of oxidation wind tube outlet area; The area of each oxidation air venthole 16 is no more than 15mm; Under the effect of the slurry stream that agitator 2 promotes, the diameter of single isolated bubbles is not more than 15mm, has increased the contact area of oxidation air and desulfuration absorbing tower slurries in the time of can guaranteeing to move; Oxidation air is well contacted with the desulfuration absorbing tower slurries, improve the oxidation air utilization rate; 2, reduce oxygen sulphur ratio, can reduce the demand of oxidation air, reduce the oxidation fan energy consumption, reach energy-conservation purpose; 3, the present invention's porous air oxidation air pipe that the oxidation air tube terminal is horizontal is processed into streamlined section; The thrust that makes the oxidation air tube terminal receive the slurry stream horizontal direction is reduced to 1/5th of porous air oxidation air pipe; Reduce and wash away the vibrations of generation, and reduce wear.　　
Adopt the present invention can improve the utilization rate of oxidation wind, guaranteeing can not influence desulfuration efficiency because of oxidation wind is not enough at oxygen sulphur than 3.0 o'clock, reached advanced international level.
