Abstract
The utility model discloses a two-in-one flue gas desulfurization tower comprising a tower body, an outer cone, a chimney, an upper desulfurization liquid distributor, a lower desulfurization liquid distributor, an inner head, a riser, a rise hood, a flue gas inlet, an upper desulfurization liquid inlet pipe, a manhole, and a lower desulfurization liquid inlet pipe. The lower desulfurization liquid distributor is welded to the upper portion of the flue gas inlet. The inner head is upwardly welded on the lower desulfurization liquid distributor. The riser is welded at the upper end of the inner head. The rise hood is mounted above the riser. The upper desulfurization liquid distributor is mounted above the rise hood. After flue gas enters the tower body from the flue gas inlet and contacts with desulfurization liquid, flowing from top to bottom, in a reverse flow manner, the desulfurization liquid is collected by the inner head before entering the riser and is then re-distributed by the rise hood; the desulfurization liquid contacts with the desulfurization liquid jetted by the upper desulfurization liquid distributor for the second time, the third time and the four time; finally, the residual SO2 in the flue gas is all removed before the treated flue gas is discharged to air through the outer cone and the chimney. The two-in-one flue gas desulfurization tower is simple in structure, convenient to operate, efficient in desulfurization, and effective in desulfurization.
Description
Technical field
The utility model relates to the thermal power plant boiler flue gas desulfur device, is directly involved in two-in-one fume desulfurizing tower.
Background technology
Along with the raising of industrial expansion and people's living standard, craving for also of the energy constantly increased to the SO in coal-fired flue-gas
2Become the main cause of atmosphere pollution, reduced SO
2Pollute and become the task of top priority that current atmospheric environment is administered.The current sulfur method that generally adopts is dry desulfurization, and it is mainly to utilize solid absorbent to remove the SO in flue gas
2, generally limestone fines is sprayed in burner hearth, make its decomposes become CaO, absorb the SO in flue gas
2, generate CaSO
3, together with flying dust, at deduster, collect or discharge through chimney, although in the dry desulfurization process without the discharge of waste water, spent acid, reduced secondary pollution, its desulfuration efficiency is low, equipment is huge, and SO
2Form calcium sulfite, cause the waste of resource, it is very necessary researching and developing a kind of energy-efficient flue gas desulfur device.
Summary of the invention
The purpose of this utility model just is to provide a kind of two-in-one fume desulfurizing tower, and it can solve effectively, and the domestic flue gas desulfur device once desulfurization efficiency that generally adopts is low at present, the shortcoming that desulfurized effect is poor.
the purpose of this utility model is achieved in that a kind of two-in-one fume desulfurizing tower, has tower body, Outer Taper, chimney, upper doctor solution distributor, lower doctor solution distributor, interior end socket, riser, rise gas hood, gas approach, upper doctor solution feed tube, inspection manhole, lower doctor solution feed tube, tower body top welding Outer Taper, Outer Taper top welding chimney, tower body bottom left end welding gas approach, top left end welding inspection manhole, in tower body inside, the lower doctor solution distributor of gas approach top welding, lower doctor solution distributor is the interior end socket of welding upwards, interior end socket upper end welding riser, above riser, install and rise gas hood, above rising gas hood, install the doctor solution distributor.
the utility model is owing to having adopted in tower body inside, distributor under gas approach top welding doctor solution, lower doctor solution distributor is the interior end socket of welding upwards, interior end socket upper end welding riser, above riser, install and rise gas hood, rise the structure of installing the doctor solution distributor above gas hood, after flue gas enters tower body by gas approach, after top-down doctor solution counter current contacting, through interior end socket, collect and enter riser, through rising the gas hood redistribution, with the doctor solution of upper doctor solution distributor ejection, carry out secondary, three times, four contacts, residual SO in flue gas the most at last
2all remove, finally by Outer Taper, by chimney, enter atmosphere, this appliance arrangement is simple in structure, easy to operate, desulfuration efficiency is high, and desulfurized effect is good.
The accompanying drawing explanation
Accompanying drawing shows a kind of structural representation of two-in-one fume desulfurizing tower, below in conjunction with accompanying drawing, the utility model is described further.
The specific embodiment
tower body 1 is with cylinder of stainless steel coiled sheet weldering, upper end welding Outer Taper 2, Outer Taper 2 upper end welding chimneys 3, tower body 1 left side, lower end welding gas approach 9, upper left-hand welding inspection manhole 11, in tower body 1 inside, the lower doctor solution distributor 5 of gas approach 9 top welding, lower doctor solution distributor 5 is equidistant by the six roots of sensation that is parallel on tower body 1 cross section, symmetrical doctor solution arm forms, on every doctor solution arm, all be welded with 3 spiral nozzles, doctor solution feed tube 10 under lower doctor solution distributor 5 center welding, lower doctor solution distributor 5 is the interior end socket 6 of welding upwards, interior end socket 6 upper end welding riseies 7, above riser 7, install and rise gas hood 8, above rising gas hood 8, install doctor solution distributor 4, upper doctor solution distributor 4 is comprised of three distributors, the structure of each distributor is identical with lower doctor solution distributor 5, doctor solution feed tube 12 in upper doctor solution distributor 4 core welding.
Operation principle
Flue gas enters tower body from gas approach, with the doctor solution adverse current of lower doctor solution distributor ejection, fully contacts, and removes the SO in flue gas
2And dust, through interior end socket, collect and enter riser, by rising the gas hood redistribution, with the doctor solution of upper doctor solution distributor ejection, carry out secondary, three times, four times counter current contacting, further remove the SO in flue gas
2, the flue gas after purifying enters Outer Taper, by chimney, enters atmosphere.
