A feed port and a discharge port are respectively arranged at the upper part and the lower part of the main body of the reactor. Spacer plates are arranged at the lower part of the main body of the reactor. At least three retainers are arranged in the main body of the reactor. The retainers are not mutually crossed. At least one blanking valve is arranged on the spacer plates among every other retainer. The utility model has the advantages of reasonable structure and good effect of removing impurities in flue gas. The utility model can be used for desulfurization, denitration and dust removal for the flue gas of a power plant, a boiler, various heating furnaces and incinerators.
Description
The utility model relates to a kind of flue gas desulfur device, particularly a kind of dry method flue gas desulfur device with activated coke or active carbon.
Flue gas desulfurization can be divided into two kinds of dry method and wet methods according to the form of desulfurizing agent.At present the structure that removes SO2 and NOX device in the flue gas with dry type activated coke or active carbon as shown in Figure 1, comprise the reactor body 1 that has gas approach 11 and exhanst gas outlet 12 sealings, activated coke or active carbon bed 2 are between the gas approach 11 and exhanst gas outlet 12 of body 1 inside.In the course of work, activated coke or active carbon are static or contact with flue gas adverse current in reactor.Above-mentioned this structure makes that device has that bed 2 resistances are big, the flue gas treating capacity is little, activated coke or deficiencies such as active carbon regeneration difficulty, desulfurization intermittently operated.
The purpose of this utility model provides and a kind ofly can efficiently remove sulfur in smoke, dry method flue gas desulfur device that the flue gas treating capacity is big.
For achieving the above object, the utility model is taked following design: a kind of flue gas desulfur device, it comprises the reactor body that has gas approach and exhanst gas outlet and the bed of sealing, it is characterized in that: top and bottom at described reactor body are respectively equipped with material inlet and discharging opening.
In order to control the blanking velocity of variant position bed material in the reactor body better, the bottom is provided with one described reactor body inside is divided into not connected two-part dividing plate up and down in the described reactor body, and described gas approach and exhanst gas outlet all are positioned at top; The top of described reactor body is provided with at least three barriers, mutually disjoint between the described barrier, the base of each barrier all joins with described dividing plate, and all passes described each barrier from any more any line to described exhanst gas outlet arbitrarily of described gas approach; On the described dividing plate between described per two barriers, be provided with at least one baiting valve.
In order to make flow of flue gas unimpeded, activated coke or active carbon can be separated into several parts effectively again, close described gas approach is the venetian blind type barrier in the described barrier, near exhanst gas outlet is netted barrier; Described dividing plate between described per two adjacent barriers is provided with a described baiting valve.
From both saving manufacturing cost, can guarantee that again the angle of sulfur removal effectiveness is set out, the preferable form of the utility model is that described barrier is three, and wherein close described gas approach is the venetian blind type barrier, and two other is netted barrier; Between the described barrier, all parallel to each other between the cross section of barrier and described smoke entrance.
In order to be beneficial to the flow velocity of control activated coke or active carbon, described material inlet and discharging opening place are provided with feed valve and bleeder valve respectively.
Utilize flue gas desulfur device of the present utility model, in the process of desulfurization, activated coke or active carbon rely on gravity slowly to move in reactor, intersect with flue gas to contact, and the surface-active point of dependence activated coke or active carbon removes the SO in the flue gas
2And NO
xBed resistance is little, and flow of flue gas is unobstructed, and operating efficiency is improved greatly, and the flue gas treating capacity heightens.
Because bed has been divided into several parts by barrier, and be equipped with baiting valve on the dividing plate under every part, thereby so that the translational speed difference of activated coke (charcoal) in the bed, cause in the gas approach zone, the translational speed of activated coke (charcoal) is fast, activated coke (charcoal) translational speed is slow near the zone of exhanst gas outlet, so both prevented the dust in flue gas accumulation, the efficiency of dust collection of reactor is improved, makes the dust in flue gas concentration that enters this device can be by bringing up to 1000mg/g below the present 400mg/g.
Because activated coke of the present utility model or active carbon have adsorbed SO constantly flowing
2Activated coke (charcoal) deliver to the regenerator thermal regeneration at any time, remove the SO that is adsorbed on activated coke (charcoal) surface
2And reclaim, can not pollute environment, remove SO
2Activated coke or active carbon deliver in the reactor again and recycle.Not only reduced waste, and the desulfurization work of flue gas can be carried out uninterruptedly.
The utility model can also use plural reactor series connection, promptly can remove SO
2, NO
xEtc. plurality of impurities.The utility model can be widely used in desulfurization, denitration and the dedusting of power-plant flue gas, boiler smoke, various flue gas of heating furnace and incinerator smoke.
The utility model is described in further detail below in conjunction with accompanying drawing.
