Description
Technical field
This utility model relates to technical field of desulfurization, is specifically related to a kind of oxidation air and blows block apparatus.
Background technology
There are two 75t/h CFBBs in Jiang Zhuan gangue power & light company, flue gas desulfurization technique uses double alkali method flue gas desulfurization technology, this sulfur removal technology uses NaOH solution as desulfurization absorbent, through pump, desulfurizing agent is squeezed into absorption tower be fully contacted with flue gas, make the sulfur dioxide in flue gas carry out reaction with the NaOH in desulfurizing agent and generate Na2SO3, the Na2SO3 solution discharged from absorption tower and lime white reactive liquid solution, generate CaSO3 and NaOH, CaSO3 aoxidizes through air blast in oxidation pond, generate CaSO4 sediment, concentrated pond concentrates, clear liquid is sent into one and is sunk pond, slag filter cake otherwise processed is made after belt dewaterer filtering means dehydration, filtrate is reclaimed, return to one sink pond re-use, the source of the gas of oxidation pond is provided by two roots blowers, it is located in the pump hole in technique building,
Day-to-day operation finds: along with the prolongation of the time of operation, the electric current of oxidation fan is stepped up；Oxidized input air reduces；Sediment dehydration difficulty.Study by analysis, assert that clogging occurs in oxidation air；
After desulphurization system is stopped transport, oxidation air, the liquid emptying in oxidation pond, is checked by installation dredge pump, finds that serious phenomenon all occurs blocking in each air outlet of oxidation air, and establishment officer uses the mode descaling, dredging manually beaten；
According to related data, the blocking foulant analysis of blocking oxidation air is learnt, in foulant, major part is CaSO4.2H2O, a less part is CaSO3.0.5H2O, foulant top layer relatively hard portion is CaSO4.2H2O, contact with tube wall formed the earliest is then CaSO4.2H2O Yu CaSO3.0.5H2O mixed crystallization；
According to technological principle and chemical reaction process, when system is properly functioning, sulfur dioxide in flue gas is to enter oxidation pond with CaSO3.0.5H2O form, relation according to the sedimentation mechanism of CaSO3.0.5H2O and speed with relative saturation degree, when the degree of supersaturation of CaSO3.0.5H2O is more than 6-8, a large amount of nucleus will be generated, produce CaSO3.0.5H2O fouling the most in systems；
In order to CaSO3.0.5H2O is discharged system, it is necessary for forcing oxidation that it is changed into CaSO4.2H2O CaSO3.0.5H2O.In oxidation pond, oxidation fan is further oxidized to CaSO4.2H2O CaSO3.0.5H2O, when the degree of supersaturation of CaSO4.2H2O is more than 1.3 ~ 1.4, the nucleation of CaSO4.2H2O is occupied an leading position, generate a large amount of nucleus, and the condition of CaSO4.2H2O nucleus generation is also much easier than the Production conditions of CaSO3.0.5H2O nucleus, this is also to find that in foulant, major part is CaSO4.2H2O by analysis, a less part is the reason of CaSO3.0.5H2O, through the analysis to foulant, find that Ca2+ salt reaches 90%, CaSO4.2H2O then reaches more than 70%；
nullBy analyzing，If it follows that thoroughly to stop the generation of crystallization nucleus，Then the CaSO3.0.5H2O in System Solution thoroughly must be got rid of totally，And this can only be by thoroughly precipitation (under low consistency conditions，Precipitable completely through 50h，" the co-precipitation thing experimental study of calcium sulfite and calcium sulfate ") filter，But we also need to carry out CaSO3.0.5H2O oxidation and allow it generate CaSO4.2H2O in actual production process，To discharge it outside system，Therefore in production process, the generation of CaSO4.2H2O is also the most inevitable，And its condition producing nucleus is relatively easy to comparatively speaking，So to solve double subtraction flue gas desulfurization technique oxidation air fouling and clogging problem，It is crucial that how the fouling to CaSO4.2H2O processes.
