Abstract
A flue gas desulfurization absorption tower with rectifying device belongs to the technical field of flue gas desulfurization equipment, which aims to provide an improved flue gas desulfurization absorption tower with rectifying device which can carry out the secondary breakup for liquid drops in the absorption tower, generate a new mass transfer absorption surface, increase the absorption amount of SO2 by serous fluid per unit, and effectively improve the desulfurization efficiency. The flue gas desulfurization absorption tower is technically characterized in that rectifying devices (2) are respectively installed in tower bodies below a spraying device (3) and above a flue inlet (5) in a conventional spray absorption tower. The absorption tower realizes the rectification and redistribution for flue gas through the rectifying devices, gas and liquid can generate the strong impact effect when flue gas passes through the rectifying devices, the absorption of the absorption tower can gradually become saturated in the process of dropping of absorption serous fluid drops, and the fluid drops are broken up once more (second breakup) by high-speed rising gas flow when passing through the rectifying devices, a new mass transfer absorption surface can be generated, the absorption amount of SO2 by serious fluid per unit is increased, and the desulfurization efficiency is effectively increased.
Description
Technical field
The utility model relates to a kind of being used for and reduces the equipment that its energy consumes when Industrial Stoves wet flue gas desulfurization absorption tower device or similar field are used to improve the absorption tower mass-transfer efficiency, belongs to the flue gas desulfurization device technical field.
Background technology
Advantages such as in recent years, wet method calcium base flue gas desulfurization technique is safe and reliable to operation owing to it, desulfuration efficiency is high, sorbent utilization is high, applicability is strong are used widely.Spray column is few because of its tower inner member, desulphurization plant is less scaling and obstruction, and the pressure loss is also less, operation maintenance is comparatively easy, at present, has become first-selection in the desulfurization project at home and abroad.
After flue gas enters gas-liquid mixed district, absorption tower, contact mixing with the stripping liquid slurries under the spraying layer spray are reverse, the easy molten gas of the most gaseous states that wherein carry and the stripping liquid slurries between when mass exchange takes place and be dissolved in the absorbent slurry, thereby finish gaseous state SO
2The physics capture process, its absorption reaction speed and efficient depend primarily on the multiple factors such as relative velocity, contact area and the time of staying of flue gas and slurries.Conventional absorption tower drop surface area in dropping process constantly reduces, and the minimizing of surface area causes liquid gas contacting efficiency low, drop surface SO
2Concentration rises rapidly, thereby makes the SO in the gas phase
2Slow down or end to the mass transport process of liquid surface, reduced desulfuration efficiency.
Summary of the invention
The purpose of this utility model is to overcome absorbent slurry that conventional absorption tower exists and drips in the process, surface area reduces, absorb the problem that reaches capacity gradually, provide a kind of improved, can carry out second-time breakage to the drop in the absorption tower, produce new mass transfer sorbent surface, the unit's of making slurries absorb SO
2Amount increase, effectively improve the fume desulfurating absorption tower with fairing of desulfuration efficiency.
Its technical scheme is: a kind of fume desulfurating absorption tower with fairing, comprise tower body and the slurries pond that is installed in the tower body below, be arranged on the flue entrance of tower body below one side, be installed in the tower body, spray equipment and demister in the upper part, and the flue outlet that is arranged on the tower body top, it is characterized in that: be provided with fairing in the below of described spray equipment, place, the top of the flue entrance tower body.
Fairing is by being welded on the tower body inwall, arranging shaped steel parallel, that section assumes diamond in shape more and constitute.Form the taper reducing between the adjacent shaped steel that section assumes diamond in shape.
Its beneficial effect is: fume desulfurating absorption tower of the present utility model, by in the tower body of below spray equipment, above the flue entrance, locating fairing being set, rectification and reallocation have been realized: when flue gas passes through fairing taper reducing to going into tower flue gas, air-flow is quickened, above fairing, produce strong turbosphere, be subjected to the time spent of doing of irregular air-flow when drop, the surface local distortion, drop is flattened gradually by sphere by the gas pressure effect is elliposoidal, cup-shaped and half bubble shape; When the relative velocity of drop and high velocity air during greater than critical speed, the at first explosion of top of half bubble shape drop, form the ring-type that edge thickness does not wait, it has comprised the quality of the drop 70% of spherical size particles, makes the marginal laceration slabbing when air-flow blows on the ring-type drop, and the centre forms a large amount of little vacuoles, finally be fragmented into the fine drop and the little vacuole of various sizes, thereby produce new mass transfer sorbent surface, increased the area of gas-liquid contact effectively, improved the usefulness of mass transfer.Simultaneously, the distribution of gas in the tower on the arbitrary section is more even, has improved absorption efficiency.In addition, fume desulfurating absorption tower of the present utility model is simple in structure, and the improvement cost of increase is very low, and desulfurized effect is obvious, is a kind of ideal equipment that can improve the absorption tower mass-transfer efficiency and can reduce its energy consumption.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a fairing operation principle schematic diagram.
The specific embodiment
As shown in Figure 1, fume desulfurating absorption tower with fairing comprises tower body and the slurries pond 1 that is installed in the tower body below, is arranged on the flue entrance 5 of tower body below one side, be installed in the tower body, spray equipment 3 and demister 4 in the upper part, and the flue outlet 6 that is arranged on the tower body top.Be provided with fairing 2 in place, the top tower body of the below of spray equipment 3, flue entrance 5.
Fairing 2 is by being welded on the tower body inwall, arranging shaped steel parallel, that section assumes diamond in shape more and constitute.Form the taper reducing between the adjacent shaped steel that section assumes diamond in shape.
Evenly be provided with polylith airflow uniform distribution plate on the inwall of flue entrance 5, make the distribution of gas that enters in the tower body more even.Simultaneously, the airflow uniform distribution plates in the flue entrance 5 cooperate with fairing, make flue gas enter tower interior after, move upward in the mode of " laminar flow ", avoided inevitable " eddy current " phenomenon of conventional void tower.
Its course of work is (asking for an interview Fig. 2): when flue gas enters fairing 2 taper reducings in the absorption tower by flue entrance 5, air-flow is quickened, the fairing top produces strong turbosphere, be subjected to the time spent of doing of irregular air-flow when drop, the surface local distortion, drop is flattened gradually by spherical droplets 7 by the gas pressure effect is elliposoidal 8, cup-shaped 9 and half bubble shape drop 10.When the relative velocity of drop and high velocity air during greater than critical speed, the at first explosion of top of half bubble shape drop 10, form the ring-type drop 11 that edge thickness does not wait, it has comprised the quality of the drop 70% of spherical size particles, air-flow blows and make the marginal laceration slabbing on ring-type drop 11, the centre forms a large amount of little vacuoles 12, finally be fragmented into the fine drop and the little vacuole 13 of various sizes, thereby produce new mass transfer sorbent surface, increase the area of gas-liquid contact effectively, improved the usefulness of mass transfer.
