Description
Affiliated technical field
The utility model relates to a kind of multifunctional absorption tower that is mainly used in flue gas desulfurization, this multifunctional absorption tower can be used for multiple flue gas desulfurization technique and device, and being particularly useful for ionic liquid or organic amine liquid is the solvent absorption cycle flue gas desulfurization technique and the device of desulfurizing agent.
Background technology
In the stack gases that combustion of fossil fuel and metal smelt process produce owing to contain a large amount of SO usually
2, it must can emptying after the desulfur technology treatment and purification.Present flue gas desulfurization technique has limestone-gypsum method, ammonia process, two alkaline process, phosphorus ammonium method, ACFP, amine process, solvent absorption cycle etc.Wherein, solvent absorption cycle flue gas desulfurization technique is owing to adopt as special solvents such as ionic liquid, organic amine liquid as desulfurizing agent, and this desulfurizing agent absorbs SO at normal temperatures
2, then heating desorption goes out high-purity SO
2And make desulfurizing agent regeneration, thereby have that desulfurization process is brief, desulfurizing agent can be recycled, desulfuration efficiency height, non-secondary pollution, accessory substance sulfuric acid economic worth be than characteristics such as height, thereby become one of current the most potential flue gas desulfurization technique.
Usually, when employing is carried out flue gas desulfurization as fume desulphurization methods such as solvent absorption cycles, absorb SO in the flue gas with desulfurizing agent
2And make before flue gas is purified, the raw material flue gas need be washed cooling and be handled.In view of this, at present, practices well is that two towers are set simultaneously on sulfur removal technology, respectively as flue gas washing tower and SO
2After absorption tower, flue gas enter scrubbing tower and handle with washings countercurrent washing cooling from the scrubbing tower bottom, draw and enter SO from the scrubbing tower cat head again through pipeline
2Carry out the counter-current absorption purification with desulfurizing agent at the bottom of absorbing Tata.But above-mentioned employing double tower carries out the preliminary treatment of flue gas respectively and there is following defective in the mode of desulfurizing and purifying:
At first, the employing of two separate tower bodies increases the equipment investment of desulfurizer; Secondly, flue gas desulfurization environment for big flow, smoke conveying duct from scrubber overhead to the bottom, absorption tower need have heavy caliber and bigger length, and this has significantly improved the investment of device aspect process pipe again, has increased the installation difficulty of equipment and pipeline simultaneously; Moreover setting up also of double tower had higher requirement to the floor space of whole desulfurizer.
Summary of the invention
Be integrated degree and multifunctionality by raising main process equipment, with investment, the reduction device installation difficulty that realizes effectively reducing flue gas desulfur device, and reducing the purpose of plant area area simultaneously, the utility model provides a kind of multifunctional absorption tower that is used for flue gas desulfurization.
The technical scheme that the utility model adopted is: with the absorption tower tower body with division board from top to bottom vertical segmentation become two separate parts of pretreating zone and uptake zone, pretreating zone is in order to wash and to wash the back demist to flue gas, the uptake zone is in order to absorb SO in the flue gas
2Foam removal with the desulfurization flue gas.Division board adopts metal or nonmetallic materials, and the division board top has hole to realize the connection of pretreating zone and uptake zone.In the pretreating zone, mainly form successively from top to bottom by demist section packing layer, washings spray thrower, liquid distribution trough, washing section packing layer, washings storage tank etc.; In the uptake zone, mainly form successively from top to bottom by desulfurizing agent lean solution spray thrower, absorber portion packing layer, deflector, foam removal section packing layer, desulfurizing agent rich solution storage tank etc., wherein deflector is approximately one and is inverted " L " shape, and the bottom of its vertical part is a column supporting structural.Flue gas self-absorption tower bottom enters pretreating zone, with washings to its countercurrent washing with the cooling dedusting after after, demist is handled again, enters the uptake zone at cat head self-isolation plate top hole then, absorbs SO in the flue gas with the following current of desulfurizing agent lean solution again
2, flue gas after being purified exports to smoke stack emission again in the middle part of the self-absorption district after foam removal is handled.Washing backwater and demist section drop are delivered to the washings circulatory system in the pretreating zone at the bottom of tower; In the uptake zone at the bottom of desulfurizing agent rich solution and the tower foam removal liquid of enrichment send tower body and carry out post processing.
The beneficial effects of the utility model are, by a kind of technique device that can be used for multiple flue gas desulfurization is provided, the multifunctional absorption tower that is particularly useful for the flue gas desulfurization of solvent absorption cycle, realized washing preliminary treatment, absorption cleaning function simultaneously with single absorption tower to flue gas, thereby effectively satisfied desulfurizer to low investment, easily install, floor space will be tried one's best little requirement, is specially adapted to the bigger operating mode of flue gas treating capacity.
