Specific embodiment
The utility model is described in detail below by specific embodiment combination attached drawing, it should be noted that do not conflicting
In the case where, the feature in the embodiments of the present invention and embodiment can be combined with each other, the protection model of the utility model
It encloses and is not limited to this.
As depicted in figs. 1 and 2, in order to make the exhaust gas full combustion discharged in low-temperature zone sintering process with up to standard, this reality
A kind of direct-fired soot processing device is provided with novel, which includes kiln, and the kiln includes furnace body 1, in the furnace
The front side of body 1 is equipped with fire door 2, is equipped with flue 3 in the rear side of furnace body 1, the furnace body 1 is connected by flue 3 with chimney 4, furnace
The exhaust gas of generation of burning in body 1 is discharged through flue 3 and chimney 4.The utility model is directly installed in existing using direct-injection burner 5
The necessary place of flue gas in flue 3: 4 bottom throat of chimney.That is, being equipped with burning group on flue 3.The burning group
Including direct-injection burner 5, the gas pipeline 6 being connected with the direct-injection burner 5, the natural gas being arranged on the gas pipeline 6 is cut
Only valve 7, the pulse type ignitor 9 being disposed adjacent with the direct-injection burner 5.When in use, natural gas shut-off valve 7, combustion are opened
Gas is delivered to direct-injection burner 5 by gas pipeline 6, lights the combustion gas at direct-injection burner 5 by pulse type ignitor 9, into
And realize igniting, the exhaust gas around direct-injection of igniting burner 5.Combustion fan 10, the combustion fan are equipped on the flue 3
10 for blasting enough air, so that exhaust gas full combustion.The quantity of the burning group can be configured as needed.It is preferred that
, the burning group is equipped with four groups altogether, which is not uniformly arranged on the left and right sides of flue 3, as shown in Fig. 2,
It is respectively separated in the left and right side of flue 3 equipped with two groups 5 groups of direct-injection burner.Preferably, the setting of combustion fan 10 exists
The rear side of the flue 3.In the firing stage, when 150 degree of integrated temperature or so in furnace body 1, the organic matters such as dextrin in grinding wheel grinding tool
Start outlet, wherein the black pollutions object such as carbon granules starts to discharge, and opens natural gas shut-off valve 7 at this time, combustion gas is enable to pass through peace
Direct-injection burner 5 mounted in 4 bottom of chimney, and after the igniting of pulse type ignitor 9, the combustibles such as the black flue gas of approach herein
Matter is immediately by open fire full combustion so that the black gas of discharge becomes colorless, discharge gas based on carbon dioxide and steam,
To reach qualified discharge, cleaning ambient.And reach 500 degree or so to firing temperature, it is closed without combustible component in flue gas
