Abstract
The utility model relates to an incinerator for processing nitrogen oxide exhaust gases, which can process the nitrogen dioxide exhaust gas. The utility model mainly comprises a furnace body, a main burner, an igniter, a primary air inlet and an auxiliary air inlet. The utility model is characterized in that the primary air inlet and an exhaust gas inlet are connected with each other and are installed on the main burner. The main burner is provided with a gas distribution plate. An air jacket is arranged out of the furnace body, and a three stage auxiliary air distributing hole is arranged on the furnace body. The utility model makes the burning sufficient. The auxiliary air is preheated by the air jacket and then enters a furnace hearth. On one hand, the utility model enables the unsafely burned fuel oil to burn sufficiently; on the other hand, the utility model can reduce the temperature of flue gas. The air jacket can also insulate the heat and can reduce the temperature of a furnace wall.
Description
The utility model relates to a kind of incinerator of handling nitrous oxides exhaust gas.
For treatment of waste gas, especially the waste gas of oxidizing atmosphere such as NOx if adopt absorption process, exist absorption not thorough, and the waste liquid after the absorption becomes another kind of liquid stain sources, if adopt the catalyst reduction method, operation easier is big.Existing incinerator all is to be used for the disposal of refuse solid waste, and incineration firing is fallen, and does not also have a kind of being applicable to burn the NOx waste gas combustion furnace at present.
The purpose of this utility model provides a kind of fuel oil incinerator of handling oxidizing atmosphere NOx waste gas.
The purpose of this utility model is achieved in that and comprises body of heater, main burner, igniter, the primary air inlet, exhaust gas entrance, the auxiliary air inlet, main burner, igniter is contained on the end socket of stove, it is characterized in that primary air inlet is communicated with exhaust gas entrance and is contained on the main burner, the front end of main burner is equipped with gas distribution grid, primary air mixes the feeding burner hearth with waste gas, there is air jacket the body of heater outside, the auxiliary air inlet is communicated with air jacket, be evenly equipped with auxiliary air distribution hole on the air jacket inner furnace body circumference and be provided with three grades, auxiliary air distribution hole and air jacket, burner hearth is communicated with.
Described gas distribution grid can be a Circular Plate, is opening 8-24 seam on it.
The quantity in aforesaid auxiliary air distribution hole is 4 of the first order, 8 of the second level, 12 of the third level.
The used fuel oil of aforesaid incinerator can be kerosene or diesel oil.
When using this stove, from the primary air inlet is the tolerance feeding primary air of 0.5-1.3 by coefficient of excess air, it is 1.05-5 that auxiliary air feeds the total coefficient of excess air in back, open igniter, the fuel oil that main burner feeds is lighted, survey temperature in the stove from thermometer hole, when temperature in the stove reaches 500 ℃, feed the nitrogen dioxide waste gas of 10-100% from exhaust gas entrance, adjust the primary air air inflow simultaneously, making the coefficient of excess of interior primary air of stove and nitrogen dioxide total oxidant is 0.5-0.96, auxiliary air feeds the back and guarantees that total coefficient of excess air is 1.05-5, to guarantee completing combustion, discharging tail gas reaches national specified discharge standard through thief hole 14 sample analysis.
The utility model has following advantage compared with prior art:
1. the utility model burns waste gas completely, because the effect of gas distribution grid makes after waste gas and the primary air warp, is in the rotation mode feeding burner hearth and fully burns with fuel oil.
2. owing on the body of heater air jacket is arranged, auxiliary air after auxiliary air inlet enters the chuck preheating again the hole of auxiliary air distribution vertically enter burner hearth, on the one hand the fuel oil of not burning is fully fully burnt, can reduce flue-gas temperature on the other hand, another of air jacket act as heat insulation, reduced furnace wall temperature.
