Abstract
The invention provides a semi-dry method of defluorination, desulfurization and dust removal equipment for flue gas from a kiln, including a process water tank, a process water pump, a primary process water flow meter, a Venturi section structure of a defluorination tower, a leak-proof cap, and a structure of a waste dust packing transport vehicle , defluorination tower structure, secondary process water flow meter, outlet flue of defluorination tower, cyclone separator, outlet flue of cyclone separator, discharge pipe, primary exhaust pipe, defluorination tower return chute, lime Powder bin structure, primary connecting pipe, manual valve, desulfurization tower outlet flue, flue outlet pipe, desulfurization tower Venturi section, desulfurization lower nozzle, desulfurization upper nozzle, desulfurization tower, flue gas induced draft fan, bag dust removal cylinder structure, desulfurization Tower return chute and secondary smoke exhaust pipe. The setting of the main body of the defluorination tower and the desulfurization tower of the present invention is beneficial to defluorination first and then desulfurization without mutual influence, which improves the effect of desulfurization and defluorination; Speed is controlled.
Description
technical field [0001] The invention belongs to the technical field of environmental protection dust removal equipment, and in particular relates to a kiln flue gas semi-dry defluorination, desulfurization and dust removal equipment. Background technique [0002] The existing coal-fired flue gas purification is mainly desulfurization. The desulfurization device generally includes a reactor nested in the shell. The reactor is equipped with an absorption liquid atomization spray device. The flue gas enters from the upper end of the reactor and is mixed with the fog. After the absorbed liquid (generally ammonia water) is reacted and absorbed, it enters the interlayer between the reactor and the shell through the dehydration demister at the lower end of the reactor, and then is output from the flue gas outlet provided on the shell. On the one hand, due to the short reaction process, the existing desulfurization devices cannot meet the treatment of a large amount of flue gas cont...
