Description
Technical field
This utility model relates to activated carbon method smoke eliminator, and this device belongs to a kind of air contaminant treatment that is applicable to
Activated carbon method smoke eliminator, relates to field of environment protection.
Background technology
For the sintering device flue gas of industrial smoke, especially steel and iron industry, use and include activated carbon adsorber and parsing
The desulphurization and denitration device of tower and technique are more satisfactory.Including the de-of activated carbon adsorber and Analytic Tower (or regenerator)
In sulfur, denitrification apparatus, activated carbon adsorber is for from sintering flue gas or waste gas (the especially sintering cigarette of the sintering machine of steel and iron industry
Gas) absorption pollutant including oxysulfide, nitrogen oxides and dioxin, and Analytic Tower is for the hot recycling of activated carbon.
Activated carbon desulfurization has that desulfurization degree is high, can realize denitration simultaneously, de-two English, dedusting, do not produce waste water and dregs
Etc. advantage, it it is the most promising flue gas purifying method.Activated carbon can at high temperature regenerate, when temperature is higher than 350 DEG C, and absorption
Pollutant generation fast resolvings such as oxysulfide on the activated carbon, nitrogen oxides, dioxin or decompose that (sulfur dioxide is solved
Analysis, nitrogen oxides and two English are decomposed).And along with the rising of temperature, the reproduction speed of activated carbon further speeds up, regeneration
Time shortens, and preferably in general control Analytic Tower, regenerating active carbon temperature approximates 430 DEG C, therefore, preferably resolves temperature
Degree (or regeneration temperature) be such as 390-450 DEG C of scope, more preferably 400-440 DEG C of scope.
Traditional active carbon desulfurization technique is as shown in fig. 1.Flue gas is introduced adsorption tower by booster fan, sprays into entering tower mouth
Ammonia and the mixed gas of air, to improve NOXRemoval efficiency, flue gas after purification enters and sinters main smoke stack emission.Activity
Charcoal is joined in adsorption tower by tower top, and moves down under the effect of drawing mechanism at the bottom of gravity and tower.Analytic Tower work out
Property charcoal be delivered to adsorption tower by 2# activated carbon conveyer, the activated carbon after adsorption tower absorption pollutant are saturated is discharged by bottom, row
The activated carbon gone out is delivered to Analytic Tower by 1# activated carbon conveyer, carries out regenerating active carbon.
The effect of Analytic Tower is by the SO of activated carbon adsorption2Discharge, simultaneously temperature more than 400 DEG C and certain
Under the time of staying, two English decomposable asymmetric choice net more than 80%, activated carbon is cooled, again recycle after screening.The SO discharged2Can
Sulphuric acid etc., the communicated device of activated carbon after parsing is sent to adsorption tower and is re-used to adsorb SO2And NOXDeng.
NO in adsorption tower with Analytic TowerXThere is the reactions such as SCR, SNCR with ammonia, thus remove NOX.Dust is by absorption
Being tightly held by activated carbon during tower, the vibrosieve in Analytic Tower bottom is separated, sieve under send to ash silo for active carbon powder, then may be used
It is sent to blast furnace or sintering uses as fuel.
Use activated carbon method to carry out gas cleaning, in order to improve clean-up effect, flue gas can be made to pass through multilamellar active carbon bed.
Multilamellar active carbon bed is arranged and is broadly divided into up-down structure and front-end geometry, as shown in Figure 2.In tower, active carbon bed is one whole
Body, activated carbon utilizes gravity uniformly to move down.Along the flow direction of flue gas, the first flue gas with the activated carbon adsorption of smoke contacts
In more multi-pollutant, discharge together with later active charcoal, can cause later active charcoal unadsorbed saturated just discharge tower in or front
Face activated carbon adsorption is saturated still does not plays gas cleaning effect in tower.
Prior art takes the adsorption tower of tandem structure, as shown in Figure 3, but need to increase the conveying of a set of activated carbon
Device, not only increases investment and operating cost, also increases extras maintenance workload.
Therefore, for investment reduction and operating cost and improve clean-up effect, more reasonably active carbon purifying need to be used
Device.
