Description

A kind of system for desulfuration and denitration

Technical field

The utility model relates to activated carbon method flue gas purification device, which belongs to a kind of suitable for air contaminant treatment Activated carbon method flue gas purification device is related to field of environment protection particularly for the system for desulfuration and denitration of the purification of sintering flue gas.

Background technique

For the sintering device flue gas of industrial smoke, especially steel and iron industry, using including activated carbon adsorber and parsing The desulphurization and denitration device and technique of tower are more satisfactory.It is including the de- of 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) pollutant of the absorption including oxysulfide, nitrogen oxides and dioxin, and Analytic Tower is used for the hot recycling of active carbon.

Activated carbon desulfurization has desulfurization degree height, denitration can be achieved at the same time, de- dioxin, dedusting, do not generate waste water and dregs The advantages that, it is extremely promising flue gas purifying method.Active 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, dioxin on the activated carbon generation fast resolving or decomposition Analysis, nitrogen oxides and dioxin are decomposed).And as the temperature rises, the reproduction speed of active 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 Spending (or regeneration temperature) is for example in 390-450 DEG C of range, more preferably in 400-440 DEG C of range.

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 Under residence time, dioxin decomposable 80% or more, active carbon recycles again after cooling, screening.The SO released₂It can Sulphuric acid etc., the communicated device of active carbon after parsing are sent to adsorption tower and are re-used to absorption SO2 and NOX etc..

SCR, SNCR etc. occurs with ammonia with NOX in Analytic Tower in adsorption tower to react, thus De NO X.Dust is passing through suction It is tightly held by activated carbon when attached tower, the vibrating screen in Analytic Tower bottom end is separated, 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 passes through active carbon bed, exhanst gas outlet dust can be controlled in 30mg/m³Within, this part dust mainly by Active carbon powdered carbon of the fine particle and flue gas carried in raw flue gas Jing Guo the stylish entrainment of active carbon bed.Exhanst gas outlet It carries dust in flue gas secretly and seriously affects surrounding enviroment, cause atmosphere 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 separated, under sieving Ash cellar is sent to for active carbon powder, the qualified active carbon that is considered as staying in sieve top recycles.Currently used mesh form For square hole, side length a requires to determine according to screening, generally 1.2mm or so.However, for similarly sized for φ 9mm × 1mm The active carbon of drug sheet is sieved using this sieve, also will be regarded as qualified product.The wear-resisting compressive resistance of tablet shaped activated carbon is equal It is very low, into flue gas purification system after readily become fragment, on the one hand cause flue gas purification system due to active carbon bed by Cause resistance big in powder, to increase systematic running cost use more；On the other hand active carbon high-temp burning risk is also increased, Dust is mainly stylish by active carbon bed by the part fine particle and flue gas that carry in raw flue gas in exiting flue gas simultaneously The active carbon powdered carbon of entrainment forms, and active carbon bed powder also results in the increase of exhanst gas outlet dust more, influences surrounding enviroment, makes At atmosphere pollution.

In addition, the active carbon discharge device of the prior art includes round roller batcher and is fed rotary valve, as shown in figure 12.

For round roller batcher, in the work course, active carbon acts on round roller feed by gravity It moves down under the control of machine, the different revolving speed of round roller batcher determines the movement speed of active carbon, the discharge of round roller batcher Active 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, it is existing that active carbon can generate a small amount of bonding in adsorption process As forming block feed opening being blocked, as shown in figure 13.If feed opening blocking is serious, active carbon can not continuous moving, cause Activated carbon adsorption is saturated and loses clean-up effect, or even since active carbon accumulation of heat leads to active carbon bed high temperature, there are biggish 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 of batcher more (as long as there is one to break down, entire large-scale plant must stop work), cost are high, Maintenance and Repair are difficult, Therefore certain limitation is brought to the development of activated carbon technology.

Secondly, being had the following problems for the feed rotary valve of the prior art: this kind of for desulphurization denitration active carbon The conveying of friable particle is guaranteed the air-tightness of tower body using rotary valve one side, on the other hand realizes the lossless fortune of material It is defeated, but if the rotation in rotary valve transmission process due to blade causes pumped (conveying) medium to be sheared, referring to attached drawing 12, will cause The increase of systematic running cost.Shearing phenomenon simultaneously will cause valve body wear, and air-tightness is 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 a few tons of active carbon in adsorption tower, manual demolition is with maintenance or again Newly install it is extremely difficult, caused by shut-down influence and loss be difficult to imagine.
