4Wash-out comes out, and enters the dilute sulfuric acid pond, when sulfuric acid concentration in the pond reaches 20% left and right sides, changes the shower water in the dilute sulfuric acid pond again.So constantly periodic duty, thus realize absorption, resolve, dry three kinds of operating procedures carry out synchronously.
Below provide relative theory analysis of the present invention and checking computational process:
The method that fixed bed flue gas desulfur device of the present invention specifically adopts the nozzle spray to resolve, the inventor is analyzed according at present existing 4 kinds of different analytic methods:
Method I: after adsorption process finishes, adsorption column air inlet and water discharging valve are closed simultaneously, 1000ml distilled water is injected adsorption column active carbon is carried out the immersion of 3min, when soaking, use agitator that active carbon is stirred.
The method II: process is with the method I, but do not add whipping process.
The method III: highly locating to be provided with the aperture apart from bed 0.5m in adsorption column is that 0.2mm, thickness are the stainless steel orifice plate of 50mm, and adsorption process is closed intake valve after finishing, and the opening water discharge valve evenly drenched adsorption column with 1000ml distilled water in 3 minutes.
The method IV: highly locate to install 1/2''PZ5095 * 45J type nozzle and supply water with circulating pump apart from bed 0.5m in adsorption column, water-washing process is with the method III.
Four kinds of methods analyzing efficiency in suction-parse cycle for the first time sees Table 1.
As shown in Table 1, the analytic method of soaking and stirring has the highest analyzing efficiency, this is because stirring action makes absorbent particles be contacted fully with fluid, and under the high speed turning effort, the turbulence effect that fluid produces obviously strengthens the diffusion of adsorbate in fluid, mass tranfer coefficient increases greatly, thereby can more fully resolve.And the minimum reason of static immersing analyzing efficiency is: under the fluid inactive state, and the H of ADSORPTION STATE
2SO
4The power that molecule can only rely on dissolution to produce is separated from adsorbent, along with H near the solution adsorbent surface layer
2SO
4Molecule intensive, this diffusion weakens gradually, when diffusion power during with the diffusional resistance balance, promptly can not continue parsing.
The new active carbon of MHY30 type is inhaled-analyzing efficiency of parse cycle for the first time under the different analytic methods of table 1
（m

Yet in the real practical application, the method for immersion also is difficult to be applied to successional industrial production, and the water spray type analytic method is a kind of relatively actual analytic method.In two kinds of water spray type analytic methods, the parsing amount that the nozzle spray is resolved is slightly larger than orifice plate trickle parsing amount.This mainly is that percolation flow velocity has certain difference in two kinds of analytic methods because under the identical situation of trickle amount.In the orifice plate trickle process, because current only depend on the gravity effect dirty naturally, orifice plate has bigger local flow resistance again, makes the initial velocity of current very low.And in the nozzle spray, owing to have certain pressure head, water outlet has certain speed, and 1/2''PZ5095 * 45J type nozzle that this experiment is adopted under the pressure of 0.1Mpa, goes out water speed and is about 2.41m/s.Therefore, through experimental studies have found that, when the trickle height is all 0.5m, the percolation flow velocity when adopting the nozzle spray to resolve is about the orifice plate trickle when resolving 1.5 ~ 2.0 times.
In addition, the active carbon desulfurization adsorption process is as shown in Figure 7 under the existing hygrometric state.Sulfur dioxide is to remove from flue gas by physical absorption and chemisorbed dual mode under the as can be seen from the figure existing hygrometric state.For the allovitalism charcoal, the SO of active carbon under the hygrometric state
2The intragranular diffusion coefficient is less than the active carbon under the anhydrous condition, thereby proved that further active carbon is to SO under the water condition
2Absorption be a kind of chemisorbed, it has slower adsorption rate.
Yet active carbon is to rely on inter-molecular attraction that adsorbate is adsorbed on the physical absorption that adsorbent shows to the absorption of sulfur dioxide fully under the dry state, itself and present stage the active carbon flue gas desulfurizing theory have essential distinction.For realize adsorbing, the continuity of parsing, dry run, the special workspace of making three cycle rotations of the present invention.And utilize the flue gas of discharging by economizer, and the air that dry run is needed carries out preheating earlier, and one side has reduced the temperature of flue gas itself, promotes adsorption process to carry out smoothly, because absorption is exothermic process, reduces flue-gas temperature and helps the adsorption process generation.Solve the hot blast of the required acquisition of dry run on the other hand, saved the needed energy of heating hot blast.
In order to verify that heat exchange can obtain to heat the hot blast energy needed to fixed bed flue gas desulfur device of the present invention through heat exchanger, the spy has carried out following calculating and has been verified:
The flue gas that feeds the fixed bed flue gas desulfur device is through temperature t behind the economizer
1Be 160 ℃, the concentration C of sulfur dioxide in flue gas
1Be 4500 mg/m
3, exhanst gas outlet concentration is coal-burning boiler II period national standard C
2Be 900mg/m
3, promptly desulfuration efficiency 80%, and flue gas flow L is 36000m
3/ h.Because active carbon is stabilizing to 25 ℃, pressure is that the equilibrium adsorption capacity S under the 100kpa is 10%, so required quality of activated carbon is:
In order to make the active carbon dry run carry out smoothly, need to carry out preheating through heat exchanger and obtain hot blast air, preheating institute calorific requirement is flowed through by flue gas and air, and heat exchange obtains behind the heat exchanger.Before the preheating, air themperature t
2Be 20 ℃ of normal temperature, the air themperature t after preheating
3Be 50 ± 5 ℃, relative humidity d
1Be 10%, flue-gas temperature t after lowering the temperature
4Be 60 ± 5 ℃, the utilization countercurrent action is carried out heat exchange.The required gasification latent heat of evaporation water steam is provided by the hot-air that flows through dry section in the dry run, the hot-blast outlet temperature t
5Be 10 ℃, relative humidity d
2Be 100%.According to the heat balance principle:
,
In the formula:
---the required gasification latent heat that provides of dry run, KJ/kg;
The required gasification latent heat that provides of dry run is:
In the formula:
---the quality of institute's evaporation water steam, kg;
In order to guarantee the adsorbance of adsorption process, according to the change curve of charcoal absorption amount with the active carbon moisture content, thus need to make the dried active carbon moisture content of process less than 5%, and the calculating of present embodiment reality is taken as 0.Active carbon moisture content after resolving is 50%, then per hour needs the quality of transpiring moisture to be
Kg, i.e. 648kg, evaporating required gasification latent heat Q is 1644624KJ, establishing dry run heat transfer efficiency k is 50%, so the hot blast rate that per hour needs to feed is
Kg/h.Because the density of air
Be 1.293kg/m
3So, be roughly equal to 62289.1m3/h.If flue-gas temperature is the same with air enthalpy, then the heat exchange efficiency of required heat exchanger is,
, and actual engineering can satisfy such heat exchange efficiency fully, visible dry run institute energy requirement can be obtained by flue gas and hot blast heat exchange fully.
