Description
Technical field
The invention belongs to flue gas desulfurization technique field, and in particular to a kind of active coke dry-method desulfuration device regenerator waste heat is returned
Receive system and method.
Background technology
Active coke dry-method desulfuration is using the SO in activated coke and fire coal boiler fume2Under effect, with water, the oxygen in flue gas
There is chemical reaction in gas, generate sulfuric acid.Adsorption saturation SO2Activated coke afterwards flows into regenerator from adsorption tower, flows separately through preheating
Section, parsing section, cooling section activity recovery, finally by lifting means such as conveyers adsorption tower circulation absorption is sent back to.
Illustrate by taking accompanying drawing 3 as an example, in the prior art, the thermal source of regenerator parsing section is generally from heater (such as heat
Wind furnace etc.) heat that brings of flue gas after burning, temperature is up to more than 420 DEG C；Preheating section thermal source is then from hot-blast stove high-temperature flue gas
Waste heat after parsing section heat exchange, also up to more than 330 DEG C, flue gas is from preheating section outlet (node B ') shunting for temperature：A part of cigarette
Gas is recycled in heater to mix again with the high-temperature flue gas of fuel combustion generation by hot air circulation blower and is come back to again
Raw tower parsing section, part of smoke (more than 20%) is drained off to ensure the pressure in heater, causes heat very big
Waste；Regenerator cooling section is, using cold air as cooling medium, the dump temperature of regenerator to be controlled at 110 DEG C or so,
Generally cooling section outlet (node A ') temperature can reach more than 90～100 DEG C.At present most of factories all can directly these
Arrange outside thermal source.
Regenerator parsing section typically requires that air outlet temperature reaches more than 350 DEG C, can be prevented effectively from corruption of the regeneration gas to pipeline
Erosion.And in actual production process, the temperature of resolution gas is but extremely difficult to so high temperature.Trace it to its cause mainly：
1) nitrogen comprising sealing in resolution gas, sealing nitrogen pipeline of the prior art is to connect firing equipment by nitrogen
Gas is preheating to 100 DEG C or so reconnection regenerator charging apertures, seals the temperature of nitrogen it cannot be guaranteed that meeting technique productions requirement, close
Nitrogen temperature is too low can reduce and the mixed wind-warm syndrome of resolution gas for envelope.
2) content of water is larger in activated coke resolving, and evaporation of water latent heat can consume the heat of many high-temperature flue gas.
Above prior art active coke dry-method desulfuration has the disadvantage that：
1) directly arranging outside the heat of regenerator, the utilization rate of the heat of Jing initial estimate regenerators is only 40% or so,
Energy utilization rate is relatively low.
2) outer row's temperature of desulphurization denitration flue gas is too low, causes the phenomenon for condensing to occur, and brings equipment corrosion.
Therefore, how to design a kind of active coke dry-method desulfuration device regenerator residual neat recovering system is those skilled in the art
The current technical issues that need to address.
