Description
Technical field
The utility model relates to a kind of flue gas desulfurization device, relates to the magnesium method spray type desulphurization absorption tower that has agitator particularly.
Background technology
Acid deposition and SO
2Pollute is the great environmental problem that international scientific circle and national governments are concerned about always.The Japan and the U.S. take the lead in implementing control SO from the beginning of the seventies
2Since the discharging strategy, many countries have formulated strict SO2 discharge standard and medium-term and long-term control strategy in succession, have quickened control SO
2Paces.
Existing hundreds of at present flue gas desulfurization techniques come out, and have thousands of cover flue gas desulfur devices to put into operation.Flue gas desulfurization technique can be divided into three kinds of wet desulphurization technology, semi-dry desulphurization technology and desulfurization by dry method.Wherein wet desulphurization technology mainly comprises limestone-gypsum method, sea water desulfuration method, soda method, magnesium oxide method etc.In wet method, dry method and semi-dry desulphurization flue gas desulfurization technique,, have all over the world widely to utilize owing to wet desulphurization technical efficiency height, stable etc. is had a few.Owing to the lime stone wide material sources, cheap in Wet technique, so occupy leading position in the lime lime-gypsum method wet method at home and abroad.
Show according to coal research survey of organization of International Energy Agency: wet desulphurization account for the world install flue gas desulfurization the unit total capacity 85%, wherein limestone-gypsum method accounts for 36.7%, other wet desulphurization technology accounts for 48.3%.
External desulfur technology mainly concentrates on limestone-gypsum method.Particularly, the lime lime-gypsum method is to adopt lime stone slurry to squeeze in the absorption tower by the slurries supply pump, sprays by circulating in the tower of circulating pump in the absorption tower, contacts fully with flue gas, finally reaches the desulfuration efficiency of design.
The ratio why limestone-gypsum method accounts for is higher, is because limestone is easy to acquisition, low price, desulfurization degree can reach more than 90%, therefore is used widely.But limestone-gypsum method exists Ca/S than active low, characteristics such as absorbability is little, gas liquid ratio height high, calcium hydroxide, cause that equipment is huge, floor space is big, equipment investment is high, operating cost is high and equipment is perishable, wearing and tearing, problems such as fouling, obstruction easily take place in system.In addition, its byproduct desulfurated plaster does not often reach the quality of commodity gypsum, abandons mostly, and this not only causes the serious waste of sulphur resource but also produced a large amount of solid waste.
Lime stone gypsum fado is applicable to the cauldron desulfurization in addition, for the medium small boiler desulfurization, its inferior position is arranged, and investment is big, and the accessory substance utilization is difficult to scale.
Domestic because the magnesia aboundresources, therefore produced the magnesium method desulfur technology that carries out desulfurization with magnesia as desulfurizing agent, owing to absorbed the experience of lime lime-gypsum method, its technological process is similar to the lime lime-gypsum method, all be to have adopted the absorption tower core apparatus to carry out desulfurization, but difference is in concrete sized data and operational factor.Recently, magnesium method desulfurization patented technology a handful of countries such as also began in the U.S., Japan, Korea S, Taiwan or the area is applied in recent years.With respect to limestone-gypsum method, magnesium oxide method has many advantages: its accessory substance magnesium sulfite, magnesium sulfate dissolubility are good, do more harmless abandoning (yet there are no be used for the production fertiliser containing magnesium or directly calcining generate the higher sulfur dioxide gas system sulfuric acid of purity correlation engineering report).
But, existing magnesium method desulfur technology produces owing to absorbing lime stone gypsum law technology mostly, though improve to some extent, but the design concept and the designing requirement of still continuing to use the lime lime-gypsum method mostly basically, though can reach desulfurized effect preferably, not reach the optimized magnesian technology of utilizing.From whole flow process, at pulping system, absorption system, accessory substance treatment system and flue gas emission, present magnesium method desulfur technology both domestic and external also exists variety of problems, can not satisfy long-term, the stable Technology Need of user in addition.The shortcoming of therefore domestic magnesium method operation is demanded corresponding improvement urgently.
