Description
Technical Field
The utility model relates to an active carbon unloading ash handling equipment, concretely relates to active carbon unloading degree of depth ash handling ash extraction device belongs to active carbon regeneration processing technology field.
Background
The sintering flue gas in the steel industry simultaneously contains a large amount of SO2、NOxAnd pollutants such as dioxin, dust, heavy metals and the like. At present, most steel plants only deal with SO in sintering flue gas2Dust is treated without NOxAnd pollutants such as dioxin and the like are discharged outside after treatment. Along with the increase of environmental improvement and the increase of haze treatment in China, the nation requires the existing or newly-built iron and steel enterprises to remove SO2、NOxAnd dioxin and dust can be discharged after being qualified. The synchronous treatment technology for multiple pollutants in flue gas generated by sintering activated carbon can simultaneously remove pollutants such as desulfurization, denitrification, dioxin, heavy metals and the like, and the technology is gradually valued and used in the industry. The method utilizes the actions of nonselective adsorption, catalysis and the like of the active carbon to synchronously absorb and remove various pollutants, thereby achieving the purpose of purifying the sintering flue gas. The active carbon used for desulfurization and denitrification of the sintering flue gas is coal columnar active carbon, high-quality anthracite is selected as a raw material, and the active carbon is prepared by a series of procedures of kneading, extrusion forming, carbonization → cooling → activation → washing and the like of a powdery raw material and a binder. It is black in appearanceThe cylindrical active carbon has the physical and chemical characteristics of developed pore structure, good adsorption performance, high mechanical strength, high adsorption speed, high adsorption capacity, large specific surface area, easy repeated regeneration and the like. The activated carbon has the same functions as a molecular sieve and alumina, and has the functions of a catalyst and a catalyst carrier.
The active carbon is used as an adsorbent, a large amount of active carbon needs to be filled into the adsorption device before the adsorption system is put into use, the adsorption tower is filled with the active carbon to purify sintering flue gas, and the normal starting operation of the desulfurization and denitrification system is the primary necessary condition for the operation of a sintering plant under the current environmental protection requirement. Because, the discharge is outsideThe sintering flue gas is qualified without desulfurization and denitrification, and is not allowed to be discharged to the atmosphere, and the sintering machine cannot be started for production if the sintering flue gas cannot be discharged to the outside. And a large amount of fully adsorbed active carbon needs to slowly fall to a chain bucket conveyor from an adsorption tower by the weight of the active carbon, is vertically lifted and sent to an analysis tower for analysis and regeneration, pollutants adsorbed in the active carbon are released, and enriched SO2Sending the solution to an acid plant for producing sulfuric acid, and returning the resolved active carbon into the adsorption tower for recycling. Then, the active carbon in the adsorption tower is conveyed into the desorption tower for desorption through the chain bucket conveyor, the active carbon discharged from the desorption tower is conveyed into the adsorption tower through the chain bucket conveyor for recycling, and the process is a key link for normal production of the whole flue gas purification system.
The existing activated carbon unloading mode is as follows:
the active carbon that the desorption tower came out sieves out qualified particle diameter through the shale shaker and gets into the buffer hopper, and the material in the buffer hopper discharges and gets into the chain bucket conveyer and send into in the adsorption tower and recycle.
And (4) screening the activated carbon from the desorption tower by using a vibrating screen, and removing activated carbon particles with the particle size of less than 1.2mm and a small amount of dust. However, the vibrating screen cannot remove and filter all dust, and part of the ultrafine dust cannot be screened out through the vibrating screen, but adheres to the activated carbon body and enters the adsorption tower together with the activated carbon to be subjected to desulfurization and denitrification, and then enters the desorption tower again. In the past, more and more fine activated carbon dust is enriched in the system. The increase of the activated carbon dust brings destructive influence on the safety and stability of the adsorption tower. Firstly, with the increase of dust content, the ignition point of active carbon has been reduced, has increased the risk that the active carbon intensifies and catches fire in the adsorption tower. Secondly, the system resistance in the adsorption tower is increased, the power consumption of the running of a system fan is increased, and the adverse effect is brought to the production cost. Thirdly, the dust enrichment can block the developed pore structure of the active carbon, and the desulfurization and denitration efficiency of the active carbon is reduced. Fourthly, the heat exchange efficiency in the desorption tower is reduced and the energy consumption is increased when the circularly enriched activated carbon powder passes through the desorption tower.
