Description
Technical field
The utility model relates to a kind of boiler, particularly a kind of off-gas recovery boiler.
Background technology
Boiler is that a kind of heat energy or waste heat in the industrial production of discharging after the fuel combustion of utilizing passes to the interior water of container, makes water reach the heat power equipment of needed temperature (hot water) or certain pressure steam.It is a complete body that is made of " pot " (being boiler body hydraulic pressure part), " stove " (being the combustion apparatus part), annex instrument and auxiliary device.Boiler carries out simultaneously at " pot " and " stove " two parts, and water enters after the boiler, and boiler heating surface makes water be heated into hot water or the generating steam of uniform temperature and pressure in the heat transferred water that absorbs in boiler circuit, is drawn application.In the combustion apparatus part, heat is constantly emitted in fuel combustion, and the high-temperature flue gas that burning produces transmits by heat, and with the heat transferred boiler heating surface, and self-temperature reduces gradually, is discharged by flue at last.
A kind of boiler is arranged in the prior art, and it comprises body of heater, flue collector and pressure fan, is provided with the combustion chamber in the body of heater, and the combustion chamber is connected with flue collector; The air outlet of pressure fan is connected with blast pipe, and the blast pipe outlet is stretched in the combustion chamber; Blast pipe outlet inboard also is provided with oil nozzle, and the bottom of oil nozzle is connected with oil fuel tube.Its weak point is: the high-temperature flue gas that fuel combustion produces is directly emptying by the boiler main flue; this has not only caused a large amount of thermal waste, fuel consumption, has increased enterprise's production cost; and sulphur and nitrogen oxide contained in the boiler smoke all are the materials of atmosphere pollution, and its discharge index can reach several times of pollution control regulation index to decades of times when purifying.Factory's concentration of pollutant in the atmosphere in the neighbourhood can only be reduced by increasing exit flue, the problem of environmental pollution can not be fundamentally solved.
Advocate energetically in country under the overall background of energy-conserving and environment-protective, the pollution that improve boiler thermal output, reduces to environment must become one of trend of boiler development.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of simple in structure, with low cost, off-gas recovery boiler that energy utilization rate is high, low in the pollution of the environment is provided.
The purpose of this utility model is achieved in that a kind of off-gas recovery boiler, comprises body of heater, flue collector and pressure fan, is provided with the combustion chamber in the body of heater, and described combustion chamber is connected with flue collector; The air outlet of described pressure fan is connected with blast pipe, and the blast pipe outlet is stretched in the combustion chamber; Described blast pipe outlet inboard also is provided with oil nozzle, and the bottom of oil nozzle is connected with oil fuel tube, is connected with the recovery flue on the described flue collector, and described recovery flue is connected with the combustion chamber.
As further improvement of the utility model, the import department of described recovery flue is provided with the backflow fan, and the outlet of described recovery flue in the form of a ring and be arranged on the periphery of blast pipe outlet.
As another kind of improvement the of the present utility model, the import department of described recovery flue is provided with the backflow fan, and the outlet of reclaiming flue is connected with the air inlet of pressure fan.
As further improvement of the utility model, described recovery flue is provided with the cooling for reflux air channel that is connected with blast pipe.
During the utility model work, provide fuel oil by oil fuel tube to oil nozzle, heat is constantly emitted in oil inflame, the high-temperature flue gas that burning produces transmits the heat transferred boiler heating surface by heat, wherein part of smoke is discharged by flue collector, another part flue gas is back to the combustion chamber, second-time burning after mixing with air through reclaiming flue.Compared with prior art, the beneficial effects of the utility model are: simple in structure, processing and fabricating convenience, with low cost; High-temperature flue gas feedback burning has not only been improved the combustion rate of fuel oil, reduced the discharging of pernicious gas, and effective recovery waste heat, the raising chamber temperature; In addition, be provided with the cooling for reflux air channel that is connected with blast pipe reclaiming flue, so that high-temperature flue gas effectively mixes the promotion flue gas secondary combustion with air, the while can effectively avoid causing because flue-gas temperature is too high the flimsy problem of equipment.
