Gas column type activated coke regeneration gas air seal setTechnical field
The invention belongs to environment-friendly active coke technical field of desulfurization, more particularly, to a kind of gas column type activated coke regeneration gas sealing glandDevice.
Background technique
With the raising of industrial smoke discharge standard, the flue gas purification system of sintering production has been increasingly becoming the work that must haveSequence, at present gas cleaning mainly have dry and wet desulfurizing and denitrifying process.The especially work of active coke dry-method desulfuration denitration over the past two yearsSkill has become the preferred option of sintering gas purifying method.In activated coke gas cleaning engineering, activated coke is in adsorption tower interior suctionReceive sulfur dioxide, the activated coke of adsorption saturation is sent to after preheating, bringing-up section, regeneration is discharged in regenerator in regeneratorGas discharges the activated coke to rejuvenate after regeneration gas and leaves regenerator, then is transported to adsorption tower and reabsorbs sulfur dioxide, back and forth followsRing work.Activated coke particle is to mix in regenerator with regeneration gas, and regeneration gas exists by the draft of relieving haperacidity region blowerNegative pressure is formed in the middle part of regenerator, the regeneration gas convergence for releasing activated coke is evacuated to acid making system, however in the middle part of regeneratorWhen negative pressure is less than normal, when activated coke leaves regenerator, partial regeneration gas can leave together regenerator with activated coke particle,Sulfuric acid can be generated by meeting air in feed opening, corrode the equipment at feed opening and feed opening, and dioxy is even caused when seriousChange sulphur flight；When negative pressure is bigger than normal in the middle part of regenerator, air can leave at regenerator in activated coke, along activated coke particleThe opposite direction of operation drives in the wrong direction and enters regenerator, and meeting regeneration gas will large area corrosion regenerator.
The regenerator of domestic operation leaves in activated coke particle at present adds nitrogen at regenerator, it is therefore an objective to completely cut off air, sealFirmly regeneration gas.But actual effect is not satisfactory, because being influenced very greatly by operating pressure in regenerator, negative pressure is inclined in the middle part of regeneratorWhen small, when activated coke leaves regenerator, still there is partial regeneration gas can leave together regeneration with activated coke particleTower, sulfuric acid can be generated by meeting air in feed opening, corrode the equipment at feed opening and feed opening, and two are even caused when seriousSulfur oxide flight；When negative pressure is excessive in the middle part of the regenerator, air can be left at regenerator in activated coke with nitrogen, alongThe opposite direction of activated coke Particle Behavior drives in the wrong direction and enters regenerator, and meeting regeneration gas will large area corrosion regenerator.
There are many factor for above-mentioned phenomenon occur, mainly activated coke material in regeneration tower pressure interior force extreme variation and regeneratorThe mobile speed etc. of activated coke material is possible to cause the appearance of above-mentioned phenomenon in temperature extreme variation, regenerator, and corrosion is setService life that is standby, greatly shortening equipment.
Therefore, seal that regeneration gas isolation air is just particularly important in active coke desulphurizing technique, and it is current individually downThe mode of material mouth inflated with nitrogen is unstable, inappropriate.
