Description
One, technical field: the present invention relates to a kind of sulfur method chimney smoke tapping equipment, particularly relate to FGD desulfurization fume emission device and the chimney of a kind of GGH of nothing.
Two, background technology: for reducing of the pollution of discharging flue gas in coal-burning power plant's to atmospheric environment, strict carry out " thermal power plant's atmosphere pollutants emission standards ", State Environmental Protection Administration stipulates that auxiliary construction desulfurization same period facility was wanted in newly-built coal-fired plant flue gas discharging from January 1st, 2005, what the fired power generating unit of building in the past on January 1st, 2004 did not reach " discharge standard " answers the time limit transformation, and flue gas is handled through desulfurization can be discharged into atmospheric environment after reaching discharge standard.
At present, domestic flue gas desulfurization technique has multiple sulfur removal technologies such as wet desulphurization, dry desulfurization, and wherein, lime stone (or lime)-gypsum wet sulfur removal technology (being called for short FGD) technology maturation is most widely used obvious social benefit.
The FGD sulfur removal technology is made absorbent washing sulfur in smoke with lime stone (or lime), generates calcium sulfite, carries out oxidation reaction with the air that adds again, generates gypsum at last, removes sulfur dioxide, purifies flue gas.Entire reaction course is all finished in desulfuration absorbing tower, and reaction temperature is generally about 50 ℃.
Its main technique flow process is as follows: the flue gas of boiler induced-draft fan outlet, being boosted by the desulfurization booster fan enters the absorption tower after flue gas heat exchange device (cooling side) cooling.When vertical spray tower was adopted on the absorption tower, top, absorption tower was the uptake zone, and this district is furnished with spraying layer.The absorption tower circulating pump is with lime stone slurry, calcium sulfite or gypsum mixed serum are sent into the nozzle atomizing, atomization slurry is from top to bottom by sulfur dioxide uptake zone, absorption tower, contact the generation chemical reaction with air-flow, flow into bottom, absorption tower reactive tank after generating calcium sulfite, blast air by oxidation fan, calcium sulfite oxidation becomes calcium sulfate-dihydrate gypsum.Flue gas behind the desulfurizing and purifying enters flue after demister is removed drop, heat up the back to smoke stack emission by swinging flue gas heat exchange device (GGH) again.Swinging flue gas heat exchange device (GGH) is set 2 effects are arranged.The one, reduce the former flue-gas temperature that enters the absorption tower, satisfy the requirement of sulfur removal technology, the heat of its cooling is used to heat clean flue gas; The 2nd, utilize the heat of former flue gas to heat clean flue gas, improve exhaust gas temperature (the general requirement is not less than 80 ℃), make the flue gas of chimney breast that enough rising heights be arranged, thereby improve the environmental quality of ambient atmosphere.But the investment of GGH flue gas heat exchange device is huge, reaches more than 3,000 ten thousand yuan, and the operation energy consumption height reduces thermal power plant's economic benefit.
Facts have proved of the operation of wet desulphurization in recent years, the problem that GGH exists when operation is more, and the negative effect that brings is bigger.
Since 20th century the mid-80s, the most of FGD system of U.S.'s design has abandoned GGH, adopts wet chimney operation.China's flue gas desulfurization technique is used later, in existing environmental regulation, only the SO2 content in the discharging flue gas stipulated, and to the not clear and definite regulation of exhaust gas temperature,
The advantage of the wet method FGD system of GGH is not installed: flue gas system has saved compressed air, flushing water and the steam of GGH rinse-system, and system is simplified; Solved because GGH stops up the bottleneck problem of restriction FGD operation steady in a long-term, the reliability of system is improved greatly; Reduce the engineering investment cost of FGD, shortened the completion time of project, saved floor space; Reduced the operating cost of FGD; Economic benefit is very remarkable.
So China part thermal power plant has also adopted the FGD system of cancellation GGH at present, the saturated wet flue gas that discharges after the FGD system is directly from smoke stack emission (being called for short wet smoke stack emission).Several problems that wet smoke stack emission easily produces in actual motion:
1, wet smoke stack emission causes the aggravation of chimney stack wall erosion seepage, brings potential safety hazard for the chimney overall structure.Chimney in view of present Power Plant in China, major part is prismatic straight wall construction, because the clean flue gas of the discharging of the FGD desulphurization system of no GGH is the saturated wet flue gas that temperature is low, density is high, by smoke stack emission the time, wet flue gas bump chimney internal cylinder wall, condense into drop, past dirty along inner tube wall; Simultaneously, after the flue gas process FGD system, though SO
2Content significantly reduce, but to SO in the flue gas
3Total content can only remove 40～50%, because flue gas acid dew point temperature range 105～111.6 ℃ before by desulfurization are reduced to after the desulfurization 70.5～90 ℃, and it is 50 ℃ through the clean flue-gas temperature of the FGD system that do not establish GGH, the inner wall of stack temperature is well below acid dew-point temperature, remaining SO in so clean flue gas
3Very easily dewfall is dissolved in attached in the condensation water on the chimney internal cylinder wall, makes condensation water have very strong corrosivity.
Because the version of existing chimney, chimney emission tube inwall generally is a form vertically, in order to reduce the resistance of chimney, improve the rising height of flue gas, it is straight that the operated by rotary motion of smoke evacuation tube inwall is tried one's best, in the elevation of whole inner wall of stack, the condensation water tapping equipment is not set, only enters the base plate position of inner core, perhaps be provided with the collection and the floss hole of condensation water in the base plate position that is provided with retaining cigarette wall at chimney smoke, therefore, in the process of wet smoke stack emission, the condensate liquid of inner wall of stack has only along elevation, from top to down, trickling just can obtain collecting and discharging to the bottom from the eminence to the lower.In this process, caused condensation water to the whole process corrosion from top to down of chimney internal cylinder wall.
In addition, the chimney of existing large thermal power plant is generally about 100～280 meters, condensate liquid is in trickling process from top to down, washing away of flue gas stream on being subjected to from descending, the drop that condenses is evaporated again and is entrained in the flue gas again, wet flue gas is in whole chimney uphill process, this process constantly repeats, condensation water constantly evaporates and condenses, the total amount and the acid concentration of the condensation water that on inner wall of stack, adheres to have been caused, when the temperature change of exhaust gas volumn and flue gas is little, maintain substantially on the stable concentration value.The result of this process makes inner wall of stack continue to be immersed in the very strong condensation water of certain density corrosivity, and inner wall of stack is caused lasting corrosion.
When flue gas does not discharge through desulfurization, be omnidistance negative pressure operation substantially in chimney, when flue gas during through the discharging of the FGD desulphurization system of no GGH, the import cigarette temperature of chimney is reduced to about 50 ℃ from about 120 ℃, cause smoke density to increase, reducing of chimney from draft, the chimney internal pressure is distributed to be changed, zone of positive pressure enlarges in the part chimney, when flue gas moves at zone of positive pressure, condensation water on the chimney internal cylinder wall produces permeating corrosion to barrel, makes condensation water strengthen the whole process corrosion and the lasting corrosion of inner wall of stack, accelerates corrosion process.
2, the chimney of existing structure form the secondary environmental pollution problem of so-called " chimney rain " occurs when the FGD of no GGH desulfurization fume emission.Because the FGD system discharged flue gas temperature of no GGH is lower, the outlet velocity of flue gas is lower, because clean flue gas is saturated wet flue gas, when meteorological condition is bad, when flue gas leaves chimney breast, can form condensing drip, forms so-called " chimney rain ".For example: power plant, Shandong #1, #2 unit do not have the FGD system of GGH, the FGD system of no GGH of Guangdong Province power plant second phase etc. " chimney rain " problem all take place." chimney rain " exists phenomenon commonplace in the FGD of no GGH desulfuration chimney, because of landform, and the area, wind direction, climate difference, " chimney rain " degree is different.
3, current chimney anticorrosion maintenance difficulty, the time is long, influences the main frame operation, reduces thermal power plant's economic benefit.
Owing to, need carry out maintenance and inspection timely to chimney when the corrosion situation of fore funnel.But concerning the chimney of 100～280 meters elevations, bring very big difficulty, need lifting means be installed in the exit, chimney top, set up the high-lift operation hanging cradle of professional production manufacturer production, could carry out inspection and maintenance inner wall of stack to service work.The recondition expense height, the cycle is long, and particularly two shared chimneys of unit carry out the power plant of fume emission, and two main frames all must be shut down during the chimney maintenance, make the economy of power plant loss serious.
