Background

A dry desulfurizing method by spraying calcium in boiler features that under the action of stable power gas source provided by Roots blower, the dry desulfurizing agent (limestone powder) is delivered to the boiler body of circulating fluidized-bed boiler, the heat in boiler body calcines it to active CaO particles, which react with SO2 in fume to generate calcium sulfate (CaSO4) and calcium sulfite (CaSO3), and the resultant is discharged from the slag dropping tube of boiler along with ash dregs, resulting in removing SO2 from fume. The whole process is a heat release process, releases heat, supplements the heat needed by the coal in time, stabilizes and strengthens the combustion, ensures that the combustion process is more sufficient and safer, obviously reduces the carbon content of the fly ash, and achieves the comprehensive results of saving coal, reducing consumption and improving the quality of the fly ash. In the prior art, a fan directly conveys a desulfurizer into a furnace body through a single pipeline, SO that the desulfurizer is distributed in the furnace body in a small range, and meanwhile, the desulfurizer needs to be calcined into CaO particles in the furnace body for a certain time, SO that part of the desulfurizer or the CaO particles are sunk at the bottom of the furnace body and are easily discharged from a boiler slag falling pipe together with ash, and then the distribution range of the calcined CaO particles in the furnace body is smaller, SO that the calcined CaO particles cannot be fully contacted with SO2 in flue gas, and the desulfurization effect is influenced.

SUMMERY OF THE UTILITY MODEL

In view of the above, in order to solve the problems existing in the prior art, the utility model provides an energy-saving flue gas desulfurization tower.

The technical scheme is that the energy-saving flue gas desulfurization tower comprises a boiler body, wherein the side wall of the boiler body is provided with an air inlet, the boiler body is communicated with an air supply pipe through the air inlet, the air inlet direction of each air inlet enables the interior of the boiler body to form rotational flow air, and part of the air supply pipe is tightly attached to the side wall of the boiler body and is arranged in a spiral structure.

Preferably, each air inlet is uniformly distributed in a ring shape around the axial direction of the furnace body.

Preferably, each air inlet is arranged at the same or similar height of the furnace body.

Preferably, the part of the blast pipe at each air inlet is inclined towards the upper side of the furnace body, and each air inlet is positioned at the upper end of the blast pipe.

The utility model provides an energy-saving flue gas desulfurization tower compares beneficial effect with prior art and is:

1. the spiral structure part in the blast pipe is heated through the heat that the furnace body gived off earlier to the desulfurizer before getting into the furnace body, reduces the time of calcining the desulfurizer into the CaO particle in the furnace body, and the whirl wind that forms when rethread gets into the furnace body is rotatory in the furnace body, increases the sunken time of desulfurizer on the one hand, and on the other hand increases the distribution range of CaO particle in the furnace body, better and flue gas in SO2 contact to make the desulfurizer possess good desulfurization effect in the furnace body.
