Abstract

The invention relates to the technical field of flue gas purification, particularly to a dual-cyclone dust removal and desulfurization multiplier for a wet flue gas desulfurization absorption tower. According to the absorption tower utilizing the dual-cyclone dust removal and desulfurization multiplier, a dual-cyclone multiplier and spray layers are sequentially arranged between a flue gas inlet and a flue gas outlet from bottom to top, the dual-cyclone multiplier comprises the maximum quantity of dual-cyclone multiplier units regularly arranged, each dual-cyclone multiplier unit comprises an inner cyclone cylinder arranged inside an outer cyclone cylinder, a blind cylinder is arranged in the center of each inner cyclone cylinder, the inner cyclone cylinders are provided with inner cyclone blades, and the outer cyclone cylinders are provided with outer cyclone blades. By the aid of kinetic energy of flue gas in the absorption tower, tiny particulate matters in the flue gas collide with one another, are agglomerated and are condensed into large drops when the flue gas passes through the blades of the dual-cyclone multiplier and is subjected to gas-liquid impact on walls of the cyclone cylinders, then the large drops are captured by liquid membranes on surfaces of the cyclone cylinders, so that the purification purpose of removing tiny particulate matter is achieved, the SO2 removal reaction can also be accelerated, and the removal efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a double-cyclone dedusting and desulfurization synergist used in a wet flue gas desulfurization absorption tower. Background technique [0002] At present, there are many domestic flue gas or industrial tail gas pollution control technologies, among which the relatively mature and representative technologies are: treatment of sulfur dioxide (SO 2 ) polluted limestone-gypsum method, ammonia method, double alkali method and other wet desulfurization technologies. For the current ultra-clean emission requirements, SO 2 The emission reaches 35mg / Nm3, and the dust reaches 5mg / Nm3. Conventional wet desulfurization technology generally adopts double absorption towers connected in series or single-stage absorption towers to increase the spray layer. The above-mentioned transformation plan has a long construction period, large land occupation, high construction cost and hi...
