Abstract
The present invention includes chimney, spraying absorption tower, absorbant supplying tank and waste liquid collecting pond, and features that the spraying absorption tower is set inside the chimney and fixed via the bolts embedded into the inner wall of the chimney, and the absorbant supplying tank and the waste liquid collecting pond are outside the chimney. The present invention has saving in field and low cost. In addition, the reaction product from dusting is slurry rather than solid, and this results in small dust amount, no need of other dusting apparatus and low cost in desulfurizing apparatus and operation.
Description
Technical field
The present invention relates to a kind of new process for fume desulfurization, especially a kind of chimney built-in atomizing tower washing method new desulfurization process.
Background technology
At present, China's pH value is less than 5.6 acid rain district and SO
2The contaminated area has accounted for 40% of area, and also has the trend that enlarges.In order to preserve the ecological environment, realize sustainable strategy, administer SO
2Pollute and just become the extremely urgent major issue of pendulum in face of us.Statistics shows, is discharged into the SO in the atmosphere
2Have 96% from the fuel combustion process, wherein the SO of power plant discharging
2The total amount maximum.Countries in the world are all in the exploitation of being devoted to desulfur technology and research.SO
2Control is generally set about from three links: Desulphurization of fuels, desulfurization in burning, flue gas desulfurization.Wherein flue gas desulfurization is the key link, is exploitation and the emphasis of studying.Relevant flue gas desulfurization technique is also maximum, and common has: limestone-gypsum method, spraying semidry method, magnesia absorption process, ammoniacal liquor absorption process etc., and these methods are each has something to recommend him, but shortcoming of ubiquity, required desulfurization site area is big, and investment is big, the operating cost height.The many power plant of China just are provided with the problem of considering preparation desulfurization place when designing originally.The Layout Problem of many kinds of sulfur methods is difficult to solve, and promotes very difficult.
Summary of the invention
Purpose of the present invention designs a kind of chimney built-in atomizing tower washing desulphurization new technology exactly, and it is little that this technological process has an occupied ground, reduced investment, and flow process is simple.
The present invention is achieved like this, it comprises chimney, spraying absorption tower, absorbent feeder channel, waste collection pond, the absorption tower that it is characterized in that spraying is arranged in the chimney, and with the bolting that is embedded in inner wall of stack, absorbent groove and waste collection pond are outside tower, the spraying absorption tower comprises conoidal Shell, steel pipe, steelframe, water nozzle, absorbent nozzle, steel pipe props up and stands in spraying absorption tower central authorities, steelframe is installed in top layering, water nozzle and absorbent nozzle are fixed on the steelframe, and water nozzle connects water pipe.Its technological process is: contain SO after the dedusting
2Flue gas enter spraying absorption tower in the chimney after, SO
2Atomized liquid with the ejection of absorbent nozzle mixes immediately, and with absorbent generation chemical reaction, the big drop in reaction back directly falls under the gravity effect bottom the spray tower, little droplet rises to the (operating) water nozzle place with flue gas, meet with the globule of its ejection and dissolve in wherein with its bottom, spraying absorption tower of falling, all reacted slurries are collected the waste collection pond, handle, precipitate and separate then, clear liquid enters pulping system and utilizes.This technological process can be adopted different absorbents, and the method for its liquid waste processing is also different, the lime absorption system that has commonly used, two alkali absorption systems, aqua-ammonia absorption system.
The present invention absorption tower of will spraying is arranged in the chimney, no longer other occupied ground, saved the expense of desulfurization place and device greatly, owing to enter the interior flue gas dedusting of chimney, reaction product is not collected with solid form in addition, but collect with the slurries form, therefore, the flue dust generation is little, does not need to add cleaner again, the desulphurization plant investment is significantly reduced, and operating cost also reduces greatly.
