Embodiment Construction

[0024] As shown in Figure 1, the reactor is a cylindrical tower, and the flue gas enters the reactor from bottom to top for desulfurization reaction. A square venturi distribution system (composed of a square venturi tube, a stirring device and a distributor) is installed at the flue gas inlet. The stirring device fully disperses the desulfurizer material so that it is evenly mixed with the flue gas and enters the reaction tower together. After being diverted by the guide plate, the material and flue gas undergo desulfurization reaction inside the reactor, and the state of the material and flue gas inside the reactor is between the two states of circulating fluidization and dense phase, which ensures the full progress of the desulfurization reaction. A screen filter device is installed inside the reactor to retain part of the material and let it fall through the deflector into the collecting hopper for recycling. At the same time, the screen filter device also ensures that the ...

Abstract

The circular dense phase fluidizing desulfurization apparatus belongs to the field of environment engineering technology and is one improved fume desulfurizing apparatus. The desulfurizing apparatus includes square Venturi tube, stirrer, elevator, guide unit, web plate, collecting bin, humidifier, reaction region, and material distributor. The guide unit consists of material permeating hole, guide plate skeleton and guide plate. The apparatus of the present invention has smooth running, low power consumption, easy installation and production, light dust collector load lowered by the web plate, and capacity of recovering desulfurizer for reuse.

Description

technical field [0001] The invention belongs to the field of environmental engineering, in particular to an improvement of flue gas desulfurization equipment. Background technique [0002] The dense phase dry tower flue gas desulfurization process is a semi-dry flue gas desulfurization process, which has the advantages of simple process, small footprint, low moisture content of desulfurization agent, no agglomeration, no sticking to the wall, no clogging, no corrosion, and no waste water The production, desulfurization efficiency and desulfurization agent utilization rate are high, and the by-products can be comprehensively utilized. [0003] The desulfurization reactor of the original dense-phase tower semi-dry process is a square tower body, and the flue gas enters from the upper part of the reactor. Contact, take effect, and then recycle the desulfurization agent through the bag filter to improve the utilization rate of the desulfurization agent and prolong the contact t...
