Abstract
The invention discloses a system for reducing nitrogen content of flue gas. The system comprises a nitrogen self-preparation device, a supercharger, an oxygen generation device, a boiler oil gun atomization device and a boiler hearth. An exhaust pipe of the nitrogen self-preparation device is connected to the boiler oil gun atomization device by the supercharger. The boiler oil gun atomization device sprays atomized oil into the boiler hearth for combustion. The oxygen generation device is connected to the nitrogen self-preparation device and prepares exhaust gas into pure oxygen, wherein the exhaust gas is discharged by the nitrogen self-preparation device. Compared with the prior art, the system for reducing nitrogen content of flue gas has the advantage that exhaust gas discharged by the nitrogen self-preparation device in nitrogen preparation after nitrogen adsorption is fed into a boiler air-supply system, is subjected to combustion-supporting and pressurization, and then is used as boiler heavy oil and is atomized and thus nitrogen content of boiler air-supply and heavy oil atomization processes, nitric oxides in boiler flue gas, environmental pollution, a denitration treatment cost and a whole cost are reduced.

Preferably, described induced duct is the induced duct of specification 600 × 800.
Preferably, described oxygenerator is connected with described boiler oil gun atomizing device.
The invention provides a kind of system reducing flue gas nitrogen content, comprise from nitrogen making machine, supercharger, boiler oil gun atomizing device and boiler furnace, the described waste discharge tracheae from nitrogen making machine is connected with described boiler oil gun atomizing device by supercharger, and the oil of atomization is sprayed onto boiler furnace combustion by described boiler oil gun atomizing device.Compared with prior art, the system of reduction flue gas nitrogen content provided by the invention, utilize after nitrogen gas generating system has adsorbed nitrogen in nitrogen process processed, the waste gas of discharging is used as furnace oil atomization after delivering to the combustion-supporting and supercharging of boiler supply air system, makes burning obtain oxygen enrichment burning thus Energy Saving, reduces boiler air-supply and heavy oil atomizing nitrogen content, thus the nitrogen oxide that can reduce by oil mass and boiler smoke discharge, reduce the pollution to environment, reduce denitration disposal cost, cost-saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of the system reducing flue gas nitrogen content in the embodiment of the present invention.
Detailed description of the invention
In order to those skilled in the art can understand technical scheme provided by the present invention better, set forth below in conjunction with specific embodiment.
Refer to Fig. 1, this figure is the structural representation of the system reducing flue gas nitrogen content in the embodiment of the present invention.
The system of the reduction flue gas nitrogen content that the embodiment of the present invention provides, comprise from nitrogen making machine 1, supercharger 2, boiler oil gun atomizing device 3 and boiler furnace 4, be connected with boiler oil gun atomizing device 3 by supercharger 2 from the waste discharge tracheae of nitrogen making machine 1, waste gas is through after nitrogen making machine 1 nitrogen processed, its nitrogen content is between 40% ~ 50%, again by after supercharger 2 supercharging, pressure is raised to 0.7-0.8MPa, deliver to by oil atomization in boiler oil gun atomizing device 3, the oil of atomization is sprayed onto boiler furnace 4 combustion by boiler oil gun atomizing device 3 again.
The waste gas of discharging from nitrogen making machine 1 is delivered in boiler furnace 4 by induced duct and air-introduced machine 5, and it is combustion-supporting that the air of low content is delivered to boiler furnace 4 by air-introduced machine 5.Induced duct is the induced duct of specification 600 × 800.
The system reducing flue gas nitrogen content also comprises oxygenerator 6, and oxygenerator 6 is connected with from nitrogen making machine 1 and utilizes the waste gas of discharging from nitrogen making machine 1 to make pure oxygen.Oxygenerator 6 is connected with boiler oil gun atomizing device 3, and by oil atomization, pure oxygen can play the effect of oil atomization and the combustion-supporting effect of burner hearth, reduces the nitrogen oxide that fuel produces in combustion, thus emissions reduction further.
The system of reduction flue gas nitrogen content provided by the invention, uses from the waste gas after having adsorbed nitrogen from nitrogen making machine the process of nitrogen processed.Supercharger is drawn air and is pressurized to 0.72 ~ ~ 0.8MPa, and then enter nitrogen making machine absorption nitrogen processed, after absorption, the waste gas nitrogen content of discharge is between 40% ~ ~ 50, calculates waste discharge tolerance per hour at 1500m by nitrogen making machine and supercharger suction and discharge parameter
3calculate according to this capacity and make a 600*800 airduct and both can meet pressure fan inlet scoop waste gas being guided to 1#2#3# boiler, the air of low nitrogen content is delivered to burner hearth combustion-supporting, promote that fuel burns fully in burner hearth, thus reach the target of environmental protection and energy saving.In addition, the present invention goes back it and then derives the second technology, waste gas is delivered to oxygenerator and makes pure oxygen, 0.8MPa is pressurized to through supercharger, deliver to oil gun atomized fuel oil again make flame kernel fuel oxygen-enriched combusting thus reach energy-saving and cost-reducing object, and reduce the nitrogen oxide that fuel produces in combustion, thus reduce discharged nitrous oxides.
Compared with prior art, the system of reduction flue gas nitrogen content provided by the invention, utilize after nitrogen gas generating system has adsorbed nitrogen in nitrogen process processed, the waste gas of discharging is used as furnace oil atomization after delivering to the combustion-supporting and supercharging of boiler supply air system, makes burning obtain oxygen enrichment burning thus Energy Saving, reduces boiler air-supply and heavy oil atomizing nitrogen content, thus the nitrogen oxide that can reduce by oil mass and boiler smoke discharge, reduce the pollution to environment, reduce denitration disposal cost, cost-saving.
