Abstract
A secondary smoke burning device for a roasting furnace comprises an induced draft fan (3), a valve (4), a smoke collecting pipe (5), branch pipes (6) and smoke spraying brackets (7), wherein the smoke collecting pipe which is as long as the furnace body is arranged below a middle channel platform of the roasting furnace (1); a plurality of branch pipes are arranged on the smoke collecting pipe in sections, and are respectively connected with the smoke spraying brackets; after going through diameter varying, a gas inlet of the smoke collecting pipe is connected with a gas outlet of the induced draft fan; the gas outlet is arranged outside the roasting furnace and is provided with the valve; and a pipeline which is configured with the valve and arranged at a gas inlet of the induced draft is connected with an annular flue (2) in a purification device through a flange. Smoke collected from the annular flue is sent into the roasting furnace for secondary burning via the induced draft fan and the smoke collecting pipe and through the smoke spraying brackets, and part of the smoke after burning enters a smoke purification device (9) for processing through a valve (8) under the suction action of a smoke discharge fan (10). The smoke after purification can meet the emission requirement and energy conservation and emission reduction are realized.
Description
Technical field
The utility model belongs to roaster servicing unit technical field, is a kind of baking furnace fume secondary incinerator that is used for charcoal element, metallurgy industry.
Background technology
It is the technological transformation difficult problem of charcoal element, metallurgy industry that the flue gas of roaster is handled.Major pollutants are glance coal, dust, benzo (a) pyrene, fluoride, SO in the baking furnace fume
2, CO, CO
2Or H
2Deng, more advanced flue gas processing method has at present: dry type absorption, electric fishing method, dry type add electric fishing, wet type adds electric fishing and burning method etc.
Existing gas cleaning facility is through behind the long-play, and purification efficiency all can have reduction in various degree, and clean-up effect is caused certain influence.
As adopting the electrical tar precipitator purifier at roaster, through behind the long-play, can be stained with tar and dust on the pole plate of electrical tar precipitator and the polar filament, and be difficult for rinsing well, efficiency of dust collection is reduced greatly, clean-up effect is caused certain influence.The burnt tar device of electric fishing simultaneously is the independent operating device, in case do not have standby purifier when breaking down, causes flue dust to efflux to a certain extent.Consider that with regard to needs the secondary of baking furnace fume burns problem to reach the requirement of environment purification, realizes energy-saving and emission-reduction like this.
Summary of the invention
For addressing the above problem, the utility model has designed a kind of baking furnace fume secondary incinerator, this device solves baking furnace fume handle thoroughly problem, realized the controllability of flue gas flow and good sealing effectiveness, be convenient to fast shut-off in the state of accident simultaneously.
For achieving the above object, the utility model adopts following technical scheme:
Described baking furnace fume secondary incinerator is configured to by air-introduced machine, valve, flue gas discharge, arm and aerosol spraying, wherein be arranged under the roaster center-aisle platform with the isometric flue gas discharge of body of heater, segmentation is provided with several arms on the flue gas discharge, and each arm connects with separately aerosol spraying frame again; The air inlet of flue gas discharge is through connecting with the outer fan out draft that has valve configurations that is provided with of roaster behind the reducing, and the pipeline of fan inlet after valve configurations connects with annular flue in the purifier by flange.
Because adopt aforesaid technical scheme, the utility model produces following good effect:
1, the flue gas that annular flue is collected is sent into through air-introduced machine and by the flue gas discharge and is carried out the secondary burning in the roaster, and effect is obviously thorough.Can reach the specification requirement of fume emission, realize energy-saving and emission-reduction.
2, apparatus structure of the present utility model is simple, makes easily, has wide practical value.
3, device of the present utility model has guaranteed the controllability of baking furnace fume flow and good sealing, is convenient to fast shut-off in the state of accident simultaneously.
Description of drawings
Fig. 1 is a device schematic diagram of the present utility model.
Among Fig. 1: the 1-roaster; 2-annular flue; The 3-air-introduced machine; The 4-valve; 5-flue gas discharge; The 6-arm; 7-aerosol spraying frame; The little total valve of 8-; The 9-flue gas cleaner; The 10-smoke exhaust fan; The 11-chimney.
The specific embodiment
In conjunction with Fig. 1, baking furnace fume secondary incinerator of the present utility model is made of air-introduced machine 3, valve 4, flue gas discharge 5, arm 6 and aerosol spraying frame 7, wherein be arranged under the roaster 1 center-aisle platform with the isometric flue gas discharge 5 of body of heater, segmentation is provided with several arms 6 on flue gas discharge 5, each arm 6 connects with separately aerosol spraying frame 7 again, according to producing needs, the interface that aerosol spraying frame 7 attaches self extends to the fire channel place of roaster 1; The air inlet of flue gas discharge 5 is through connecting with roaster 1 outer air-introduced machine 3 air outlets that have valve 4 configurations that are provided with behind the reducing, and the pipeline of air-introduced machine 3 air inlets after valve 4 disposes connects with annular flue 2 in the purifier by flange.
Valve 4 in the baking furnace fume secondary incinerator of the present utility model and the pipeline that is disposed are installed on the purifier annular flue 2 by flange, purifier is the device that roaster 1 itself has, and purifier is made of annular flue 2, little total valve 8, flue gas cleaner 9, smoke exhaust fan 10 and chimney 11.
During work, little total valve 8 is kept 30% aperture.The flue gas of collecting from annular flue 2 is sent into through air-introduced machine 3 and flue gas discharge 5 and by aerosol spraying frame 7 and is carried out secondary in the roaster 1 and burn, and tar, combustible burn totally substantially in gas fume after burning.Flue gas after the burning has partial fume to enter flue gas cleaner 9 processing through valve 8 under the draft effect of smoke exhaust fan 10.So flue gas that purifier produces and the flue gas recirculation said process in the secondary incinerator are also successively handled, and can reach emission request through flue gas after being purified, realize energy-saving and emission-reduction.
Device of the present utility model can guarantee the controllability of baking furnace fume flow and have good sealing that fast shut-off in the state of accident is convenient in the setting of valve 4 and little total valve 8.
