Problems solved by technology
[0006] In order to change the desulfurization agent, first prepare, precipitate, and take the clear liquid through the desulfurization dust collector liquid level control box to add the desulfurization agent under the liquid level of the impact pool to overcome the insufficient desulfurization agent replenishment dosage, low pH of the impacted liquid surface, The technical defect that leads to poor desulfurization effect, while achieving the purpose of simplifying the desulfurizer preparation equipment, provides a technical solution for the desulfurizer replenishment method to achieve high-efficiency flue gas desulfurization. The main technical content of the technical solution is: the desulfurizer and supplement The water is directly mixed to form an emulsion flow, which is continuously sprayed into the flue gas flow channel of the self-excited desulfurization dust collector to realize the supplement of desulfurization consumption

Embodiment Construction
[0014] The flue gas desulfurization agent replenishment method proposed in the application of the present invention is based on the original self-excited atomization desulfurization and dust removal method, and according to the dynamic process of flue gas desulfurization and dust removal, the consumed desulfurization dose and supplementary water should be added to directly mix to form an emulsion flow , which is supplemented by injection from the injection part arranged in the flue gas flow channel 4 of the desulfurization and dust collector. The supplemented desulfurizer emulsion enters the desulfurization and dust collector together with the flue gas emitted by combustion. Firstly, it performs mixed desulfurization in advance, and then impacts and falls into the desulfurizer solution in the impact pool 10 together with the flue gas to realize the post-stage desulfurization and dust removal process.
[0015] In order to realize the above-mentioned supplementary method of flue ...

The present invention provides desulfurizing and dedusting method, in which desulfurizer replenishing link is utilized to realize the two-stage desulfurizing and dedusting procedure, and the technological scheme of desulfurizing and dedusting set as the embodiment of the method. The present invention adopts small desulfurizer adding machine, rather than huge mechanism comprising stirring pond, stirring machine, deposition pond, high-position liquid tank, etc. and has the advantages of high desulfurizing effect.
Description
technical field [0001] The present invention relates to the technical field of sulfur-containing flue gas desulfurization and dust removal, in particular to a wet desulfurization and dust collector based on the principle of self-excited atomization of a desulfurization agent solution for flue gas, as well as a desulfurization agent replenishment method and equipment used therefor. Background technique [0002] To protect the atmospheric environment, combustion flue gas containing a large amount of sulfur dioxide that seriously pollutes the environment, such as combustion flue gas from boilers and kilns, must be desulfurized and dust-removed before being discharged. The current self-excited atomization desulfurization and dedusting desulfurization dust collector, because it is equipped with an impact pool for slag settlement, occupies a small area of equipment, and it is more suitable for using cheap lime as a desulfurization agent, so it is self-excited. Exciting desulfuri...
