The specific embodiment
See Fig. 1, Fig. 2, improved gravity bed sweetener has a housing 5, be provided with many group gravity beds 8 in the housing 5, the blade 81 that the two side of gravity bed 8 is parallel to each other by sloping inwardly constitutes, housing top is provided with the feed hopper 4 that is communicated with the gravity bed arrival end, gravity bed 8 ports of export of lower housing portion are provided with device for discharging 7, gas approach 2 and exhanst gas outlet 6 are trumpet-shaped anemostat, the pipeline of the arrival end of gas approach 2 and turbulent current generating device 1 joins, and is provided with the airflow-distribution board 3 that has some apertures in the anemostat of gas approach 2;
Device for discharging 7 is a star slot type device for discharging (referring to Fig. 2), comprise casing 75 cylindraceous, be provided with in the casing 75 by being fixed on the star slot type blow-off valve that the blade 73 that radially distributes in the rotating shaft 72 constitutes, the top of casing 75 is that feeding mouth 71 joins with gravity bed 8 ports of export, and the bottom of casing 75 is a discharge gate 74.
Extremely shown in Figure 5 as Fig. 3, turbulent current generating device 1 comprises body 11, in body 11, be provided with turbulence blades 13 with fixed part 12, the shape of turbulence blades 13 is had angle by the bending of the sheet material of two symmetrical triangles of one and forms, and the setting of turbulence blades 13 in body 11 makes its angle towards airflow direction.
Fig. 6 shows the operation principle of turbulent current generating device, and air-flow 14 forms eddy current 15 through turbulence blades 13 backs, after gas fully being mixed reach the temperature unanimity, enters desulphurization plant again.Since turbulence blades in pipeline along the airflow direction setting, overflow section between turbulence blades and the tube wall diminishes gradually, air velocity near the turbulence blades middle part is less, the closer to around, flow velocity is fast more, the flow velocity of outer gas flow is apparently higher than the flow velocity of nexine air-flow around making, thereby form the eddy current of rotation direction ecto-entad, these eddy current that differ in size continue to move ahead under the promotion of middle part air-flow, and the eddy current degree constantly reduces, and finally enter laminar condition.Eddy current fully mixes with peripheral air-flow in the process that rotation is advanced, and makes the heat of air-flow inside be able to abundant exchange, finally reaches temperature uniformity everywhere.
As Fig. 7, shown in Figure 8, have different sizes on the airflow-distribution board 3, the aperture 31 of density inequality, airflow-distribution board 3 are vertically mounted on gas approach 2 anemostats by fixture 21 rear portion apart from 1 meter in gravity bed inlet section with interior position.
Because airflow-distribution board 3 is vertically mounted on the rear portion of anemostat apart from the nearer position of gravity bed inlet section, the flue gas that enters anemostat is before flowing to gravity bed, be subjected to the retardance of airflow-distribution board, and have different sizes on the airflow-distribution board, the aperture of density inequality, the aperture that the flue gas that is obstructed passes on the airflow-distribution board enters gravity bed.Everywhere perforate density and pore size can be by experiment decision on the airflow-distribution board.By adjusting on the airflow-distribution board perforate density and pore size everywhere, can make the flue gas that passes behind the airflow-distribution board, the each point wind speed is equal substantially in gravity bed enters the mouth same section.Fig. 8 shows air-flow and was obstructed before airflow-distribution board 3 and forms the situation of eddy current 15, and speed is equal substantially everywhere through behind the airflow-distribution boards 3 for air-flow 14.
The operation principle of present device:
Sulfur-containing smoke gas 14 enters in the housing 2 behind turbulent current generating device 1 and gas approach 2 earlier, at this moment the same vertical section temperature and speed basically identical of flue gas everywhere in the equipment, passing in the gravity bed 8 lime stone 9 backs then discharges from exhanst gas outlet 6, sulfur-containing smoke gas 14 contacts with lime stone 9 when flue gas 14 passes gravity bed 8 and reacts the sulphur of removing in the flue gas at the flow direction of equipment as shown in Figure 9.Star slot type blow-off valve in the device for discharging 7 is done uniform rotation by feeding mouth 71 to discharge gate 74 along fixed-direction around the blow-off valve axis under power-equipment drives, material lime stone 9 is discharged by gravity bed 8 bottoms, in feeding mouth 71 enters the dead slot that forms between star slot type blow-off valve two blades 73, rotation along with star slot type blow-off valve, the material that enters in the star slot type blow-off valve dead slot is more and more, when star slot type blow-off valve turns over feeding mouth 71, filled material in the groove.Star slot type blow-off valve is rotated further, and when star slot type blow-off valve turns to the position of discharge gate 74, through discharge gate 74 material in the groove is discharged, and star slot type blow-off valve remains in operation and enters second charging process.Because turning over the cell body volume of the star slot type discharge machine of feeding mouth 71 in the unit interval equates everywhere, and the load mutually noninterfere at each point place, gravity bed 8 bottom, discharging speed is put faster can't arrange material more, the point that discharging speed is slower, the discharging ability of device for discharging can not occupied by other points, thereby make that the lime stone 9 that each point is discharged in the gravity bed 8 of star slot type device for discharging top is basic identical, satisfied the motion requirement of sulfur removal technology desulfurizing agent lime stone in the reaction bed.
