Abstract
The utility model provides a circulation back-burning mixed burning furnace, which belongs to the technical field of a burner burning the mixture of exhaust gas, waste residue and waste ash, in particular relates to the technology of a circulation back-burning fine ash burning furnace. The burning furnace comprises a mixed burning furnace (7), a cyclone dust collector (13), a return feeder (15), a boiler and on the like. The burning furnace is characterized in that a fluidized bed burner burning waste residue and waste ash is arranged on the lower part of the mixed burning furnace, and consists of an air chamber (1), a grid plate (3), a funnel cap and a coal feeder (2); the upper part of a mixed burning chamber is an air gas burner (6) burning exhaust gas. The cyclone dust collector (13) comprises the return feeder (15) and a cyclone (9) which are connected through a material return passage (16); a boiler comprises a boiler barrel (10), a steam superheater (11), an evaporator tube bank (12), a fuel economizer (14), an air preheater (17) and on the like. The utility model has the advantages that the circulation back-burning mixed furnace adopts the technology to reclaim fine ash for secondary combustion, which solves the problems of large quantity of ash and high combustible content of the traditional burner. Accordingly, the burning furnace can save energy and reduce the discharge of pollutants.
Description
Technical field
The utility model belongs to the combustion furnace technical field of mixed combustion offgases, waste residue, useless ash, particularly relates to the technology that the burning with fine powdered coal combustion furnace is returned in circulation.
Background technology
Original fluid-bed combustion furnace can only burn coal, and existing three wastes mixed combustion furnace separator is bulky, inferior separating effect, the thin ash of separating can only directly efflux, the thin ash of failing to separate is transported to and carries out secondary in the stove and return burning, cause the coal of considerable part in the thin ash can't completing combustion, and cause the significant wastage and the thin grey pollution on the environment of the energy.
Summary of the invention
In view of the above-mentioned deficiency of existing in prior technology, the utility model aims to provide a kind of thin waste slag can the circulation and returns the purpose circulation downward-burning type combination burner that burning reaches energy-saving and emission-reduction.
The utility model is achieved through the following technical solutions:
A kind of circulation downward-burning type combination burner, it is by mixed combustion furnace (7), cyclone dust collectors (13), material returning device (15), boiler constitutes, it is characterized in that: the bottom of mixed combustion furnace (7) is a combustion residue, the fluidized bed combustion device of useless ash, by air compartment (1), air distribution plate (3) and blast cap, feeder (2) constitutes, the top of mixing the combustion chamber is blowing-out gas burner (6) formation by burnt gas, cyclone dust collectors (13) are by material returning device (15), whirlwind tube (9) connects by returning charge road (16), and boiler is by drum (10), steam superheater (11), steam-generating bank (12), economizer (14), air preheater compositions such as (17).
The bottom of mixed combustion furnace (7) is air compartment (1) and the air distribution plate (3) and the blast cap burner of incendivity waste residue, useless ash, and waste residue, useless ash are transported in the stove by feeder (2) and fully burn under high-temperature situation with a wind; The top of mixed combustion furnace (7) is the blowing-out gas burner (6) that incendivity contains the waste gas of compositions such as carbon monoxide, hydrogen, methane.High-temperature flue gas by combustion residue, waste gas mixes the back and enters cyclone separator (13) by outlet (8) in mixed combustion furnace (7), thin grey dust in the middle of the high-temperature flue gas is separated, thin grey dust is fallen material returning device (15), by material returning device (15) thin grey dust is transported to by returning charge road (6) and carries out second-time burning in the stove, solve the problem that thin ash amount is big, combustible content is high that traditional type of furnace is discharged, directly just realized the purpose of energy-saving and emission-reduction; Carry out exchange heat through the high-temperature flue gas after the dedusting by steam superheater (11), steam-generating bank (12), economizer (14), the air preheater (17) that whirlwind tube (9) enters the boiler part, the steam that boiler produces is used for industrial production or cogeneration, and the low-temperature flue gas that is absorbed heat requires into through reaching environment protection emission behind the desulfurization and dedusting that chimney enters atmosphere.The phosphorus content of slag that combination burner and desulfurizing dust-collector are got rid of and thin ash is very low, can be used for producing the primary raw material of cement.
Compared with prior art, the beneficial effects of the utility model are conspicuous, because the technical program is taked thin grey dust recovery carrying out secondary burning technology, solved thin grey the measuring greatly that traditional type of furnace is discharged, the problem that combustible content is high, therefore can realize the purpose of energy-saving and emission-reduction, simultaneously, enter the steam superheater of boiler part by the whirlwind tube through the high-temperature flue gas after the dedusting, steam-generating bank, economizer, air preheater carries out exchange heat, the steam that boiler produces is used for industrial production or cogeneration, and the low-temperature flue gas that is absorbed heat requires into through reaching environment protection emission behind the desulfurization and dedusting that chimney enters atmosphere.The phosphorus content of slag that combination burner and desulfurizing dust-collector are got rid of and thin ash is very low, can be used for producing the primary raw material of cement.
