Description
Technical field
The utility model relates to boiler combustion equipment technical fields, and in particular to a kind of highly concentrated odor combustion device, application
The highly concentrated foul smell generated in burning paper technology.
Background technique
The highly concentrated foul smell generated in modern paper slurry industrial technology, its main feature is that calorific value is low, calorific value is about 9MJ/Nm3, and
Water content is larger, and concentration is low.It is using furnace roof torch burning (common natural gas or light oil are with burning) or feeding alkali recovery furnace burning
Industrial common method at present.Because furnace roof torch burning needs fossil fuel companion to burn, uneconomical and pollution environment, therefore at present only
It is enabled in alkali recovery furnace blowing out；And the mode for being sent into alkali recovery furnace burning is that have processing pollutant thorough, it is without secondary pollution
It generates, and sulphur can be recycled, save saltcake, existing environmental benefit, and have an economic benefit.The production process of the technology is will be high
Dense foul smell is sent into the burning of furnace high-temperature area by burner, so that the hydrogen sulfide (H2S) in highly concentrated foul smell, methyl mercaptan
(CH3SH), methyl sulfide (CH3SCH3), dimethyl disulphide (CH3SSCH3) etc. can adequately burn.
Existing highly concentrated foul smell incinerator is only sent to burner hearth by the way that highly concentrated foul smell rifle is arranged in overfiren air port, whole
A apparatus system is simply extensive to cause highly concentrated foul smell to mix with air unevenness, and highly concentrated foul smell is easy to cause to have little time burning completely
High temperature combustion zone is escaped out, and then atmosphere is discharged by boiler chimney.Existing highly concentrated odor combustion device there are the problem of have:
(1) it is only sent into alkali recovery boiler furnace by overfiren air port, highly concentrated foul smell and air mixing are uneven, are easy to cause height
Dense foul smell has little time burning and just escapes out high temperature combustion zone completely, and then drains into atmosphere；
(2) open, blowing out and when underload, in-furnace temperature is too low, highly concentrated foul smell can not active combustion it is complete；
(3) foul smell burner arrangement is unreasonable, can not be efficiently entering high-temperature region burning；
(4) a large amount of sode ash is had in burner nozzle in alkali recovery boiler operational process to be blocked；
(5) combustion case of highly concentrated foul smell can not be observed.
Therefore design the new highly concentrated odor combustion device of one kind and be necessary, it is mixed with air in addition to solving highly concentrated foul smell
It is even, guarantee burning completely, also needs to consider to open in alkali recovery boiler, blowing out and when underload, in-furnace temperature is too low, highly concentrated foul smell
It can not effectively burn completely, the necessity of auxiliary fuel is set in odor combustion device.

Heart pipe outer ring circumferentially arranges, and several foul smell pipette tips tail ends are pierced by air compartment and are connected to highly concentrated foul smell annular main pipe, described
Central tube tail end is pierced by air compartment and connection auxiliary fuel rifle.
Further preferred structure, several foul smell pipette tips include the bending linkage section of parallel-segment and tail end, described
Bending linkage section one end is connect with parallel-segment, and the other end is connect with highly concentrated foul smell annular main pipe.
Further preferred structure, the highly concentrated foul smell annular main pipe open up intake interface.
Further preferred structure, the air compartment generally tubular structure, including head end, interlude and tail end, wherein head
Outer diameter is held to be less than interlude outer diameter, the head end is connect with interlude by inclined changeover portion, and tail end is sealed equipped with sealing plate.
The inside of further preferred structure, several foul smell pipette tips is equipped with axial swirler in air compartment head end.
Further preferred structure, the air compartment tail end inside are equipped with heat-preservation cotton.
Further preferred structure, air compartment tail end end face open up flame-observing hole, igniter aperture, fire inspection hole and beat burnt hole.
Further preferred structure, the air compartment arrival end are equipped with damper, and the damper radially connects with air compartment
Logical, the damper is equipped with handle.
The utility model structure is simple, and service life is longer, greatly reduces spare part loss, and dismantle easy to use.
The utility model it is specific the utility model has the advantages that
The mixing that foul smell and air can be enhanced significantly in structure, by being arranged in the high-temperature region of alkali recovery boiler, energy
Effectively the harmful substance in highly concentrated foul smell is burnt
It burns down complete；Be reserved with simultaneously open in alkali recovery boiler, blowing out and when underload, burn the ability of highly concentrated foul smell.
It (1) is the mixing for strengthening highly concentrated foul smell and air, by arranging that more foul smell pipette tips guarantee rifle on nozzle exit
The highly concentrated foul smell that small structure sprays on head is uniform in nozzle exit；Axial swirler is then arranged in air side, will about 50~70%
Combustion air rotation, strengthen highly concentrated foul smell and mixed with the initial stage of air.
(2) aid fuel combustion rifle is set in the central tube of burner, opens in alkali recovery boiler, blowing out and when underload
And guarantee that highly concentrated foul smell burning is complete.
(3) highly concentrated odor combustion device is autonomous device, is not influenced by overfiren air port position, can be individually in alkali collection pot
It is installed on furnace, alkali recovery boiler combustion high temperature area arrangement can be chosen.
(4) because highly concentrated odor combustion device be specific installation, on burner panel be arranged flame-observing hole, igniter aperture,
Fire examines hole and beats burnt hole.
