Description

A kind of system for desulfuration and denitration
Technical field
The present invention relates to activated carbon method smoke eliminator, which belongs to a kind of activity suitable for air contaminant treatment Charcoal method smoke eliminator is related to field of environment protection particularly for the system for desulfuration and denitration of the purification of sintering flue gas.
Background technology
For industrial smoke, the especially sintering device flue gas of steel and iron industry, using including activated carbon adsorber and parsing The desulphurization and denitration device and technique of tower are more satisfactory.De- including activated carbon adsorber and Analytic Tower (or regenerator) In sulphur, denitrification apparatus, activated carbon adsorber is used for from sintering flue gas or exhaust gas (the especially sintering cigarette of the sintering machine of steel and iron industry Gas) absorption includes oxysulfide, nitrogen oxides He pollutant including bioxin, and hot recycling of the Analytic Tower for activated carbon.
Activated carbon desulfurization has desulfurization degree height, denitration can be achieved at the same time, Tuo bioxin, dedusting, do not generate waste water and dregs The advantages that, it is extremely promising flue gas purifying method.Activated carbon can regenerate at high temperature, when temperature is higher than 350 DEG C, absorption (sulfur dioxide is solved for the pollutants such as oxysulfide, nitrogen oxides, bioxin on the activated carbon generation fast resolving or decomposition Analysis, nitrogen oxides is He bioxin is decomposed).And with the raising of temperature, the reproduction speed of activated carbon is further speeded up, regeneration Time shortens, and preferably regenerating active carbon temperature is approximately equal to 430 DEG C in general control Analytic Tower, therefore, ideal parsing temperature It is for example in 390-450 DEG C of range, more preferably in 400-440 DEG C of range to spend (or regeneration temperature).
The effect of Analytic Tower is by the SO of activated carbon adsorption2It releases, while in 400 DEG C or more of temperature and centainly 80% or more , bioxin decomposable asymmetric choice net under residence time, activated carbon recycles again after cooling, screening.The SO released2It can Sulphuric acid etc., the communicated device of activated carbon after parsing are sent to adsorption tower and are re-used to absorption SO2 and NOXDeng.
SCR, SNCR etc. occurs with ammonia with NOX in Analytic Tower in adsorption tower to react, to remove NOX.Dust is passing through suction It is tightly held by activated carbon when attached tower, the vibrating screen in Analytic Tower bottom end is detached, and is that active carbon powder sends to ash cellar under sieving, then Blast furnace can be sent to or sintering is used as fuel.
After flue gas is by active carbon bed, exhanst gas outlet dust can be controlled in 30mg/m3Within, this part dust mainly by Activated carbon powdered carbon of the fine particle and flue gas carried in raw flue gas Jing Guo the stylish entrainment of active carbon bed.The cigarette of exhanst gas outlet It carries dust in gas secretly and seriously affects surrounding enviroment, cause air and particle contamination.
In addition, dust is tightly held by activated carbon when passing through adsorption tower, the vibrating screen in Analytic Tower bottom end is detached, under sieving Ash cellar is sent to for active carbon powder, the qualified activated carbon that is considered as staying in sieve top recycles.Currently used mesh form For square hole, length of side a requires to determine according to screening, generally 1.2mm or so.However, being for similarly sizedThe activated carbon of drug sheet is sieved using this sieve, also will be regarded as certified products.Tablet shaped activated carbon Wear-resisting compressive resistance is very low, into flue gas purification system after readily become fragment, on the one hand flue gas purification system is caused to hinder Power is big, to increase system operation expense；On the other hand active carbon high-temp burning risk is also increased, while in exiting flue gas The main activated carbon charcoal by the part fine particle and flue gas that are carried in raw flue gas Jing Guo the stylish entrainment of active carbon bed of dust Powder forms, and active carbon bed powder also results in the increase of exhanst gas outlet dust more, influences surrounding enviroment, causes atmosphere pollution.
In addition, the activated carbon discharge device of the prior art includes round roller batcher and feed rotary valve, as shown in figure 12.
For round roller batcher, in the work course, activated carbon acts on round roller feed by gravity It moves down under the control of machine, the different rotating speed of round roller batcher determines the movement speed of activated carbon, the discharge of round roller batcher Activated carbon, which enters to enter in conveying equipment after rotatory feeder valve discharging, to be recycled, and the main function of rotatory feeder valve is in discharge While keep adsorption tower sealing, so that the pernicious gas in adsorption tower is not leaked into air.
Due to containing certain vapor and dust in flue gas, activated carbon will produce a small amount of bond now in adsorption process As forming block feed opening being blocked, as shown in figure 13.If feed opening block it is serious, activated carbon can not continuous moving, cause Activated carbon adsorption is saturated and loses clean-up effect, or even since activated carbon accumulation of heat leads to active carbon bed high temperature, there are larger Security risk.The method handled at present be system-down after manually remove block.In addition, round roller batcher is in process of production Failure happens occasionally, such as：Material the problems such as being unable to control when material leakage situation when flue gas pressures change, parking.In addition round roller The quantity more (as long as there are one breaking down, entire large-scale plant must stop work) of batcher, cost is high, Maintenance and Repair are difficult, Therefore certain limitation is brought to the development of activated carbon technology.
Secondly, it for the feed rotary valve of the prior art, has the following problems：It is this kind of for desulphurization denitration activated carbon On the other hand the conveying of friable particle realizes the lossless fortune of material using rotary valve on the one hand in order to ensure the air-tightness of tower body It is defeated, but if the rotation due to blade in rotary valve transmission process causes pumped (conveying) medium to be sheared, referring to attached drawing 12, can cause The increase of system operation expense.Shearing phenomenon simultaneously can cause valve body wear, air-tightness to be deteriorated, and service life reduces.Especially In feed inlet heap full with substance, rotational valve core, blade and valve casing are more obvious to the shear action of pumped (conveying) medium.For usually having For the large-scale adsorption tower for having 20 meters or so height, round roller batcher or rotary valve break down in process of production, for work Continuously running for skill causes huge loss, because having loaded several tons of activated carbon in adsorption tower, manual demolition is with repair or again Newly install it is extremely difficult, caused by shut-down influence and loss be difficult to imagine.
