Embodiment Construction

[0020] The present invention can be applied separately or in combination in the accompanying figure 1 In the desulfurization system shown:

[0021] 1) The desulfurization reaction technology of swing nozzle feeding is adopted.

[0022] Attached below figure 1 The embodiment, technological process and system arrangement structure of the present invention are described in detail.

[0023] Fluidized dry flue gas desulfurization reaction steps of materials fed into the swing nozzle: it feeds slaked lime or recycled materials through the swing nozzle in the desulfurization tower; The nozzle method is used to feed into the desulfurization tower; or the swing nozzle is used to feed the quicklime CaO or the circulating material in the digestion tower; or the quicklime and the circulating material (quicklime and slaked lime Ca(OH) 2 The mixture) is mixed and fed into the digestion tower by means of a swing nozzle.

[0024] Firstly, CaO powder, the raw material of the desulfurizer, ...

Abstract

The invention is a kind of smoke desulfurizing method using swing muzzle drying method, including the producing of desulfurizing agent, the desulfurizing reaction, the separation and recycling of outer desulfurizing particles. The invention uses swing muzzle which can adjust the position and direction of material feeding, it adjusts the position and direction through swing of nozzle. The swing type includes swing up and down, right and left. It can swing about í‚30íÒvertically and about í‚45íÒflatly, the range of sidelong swing is about í‚30íÒto í‚45íÒrelative to the centre.

Description

technical field [0001] The invention relates to a fluidized dry flue gas desulfurization method using a swing nozzle to feed materials, belongs to the technical field of flue gas desulfurization, and particularly relates to a dry desulfurization system and process in flue gas discharged from various combustion equipment. Background technique [0002] At present, the treatment of sulfur dioxide generally adopts the wet lime-gypsum method (W-FGD) in foreign countries. Although the above-mentioned method has a good removal effect, it has huge investment, large water consumption, large floor area, complex system, There are a series of problems such as large resistance, complex structure, and the need to reprocess water. Compared with the conventional wet process, it has the following advantages: low investment cost; the desulfurization product is dry; there is no need to install a demister and flue gas reheater; the equipment is not easy to corrode; scaling and blockage are not ...
