Described communicating pipe is evenly distributed in the body of heater on second partition right side.
The level height of the outlet flue between described slag trap and the first dividing plate is between charging aperture lower end and air inlet upper end.
The area of described desulphurization during combustion chamber is less than 1/3 of whole body of heater area.
Adopt technique scheme, the utility model has following beneficial effect: be provided with secondary smoke-eliminating desulfurizing chamber, flue dust is through the first smoke elimination chamber and the second twice of smoke elimination chamber smoke-eliminating desulfurizing.The utility model has improved the efficiency that fuel uses in improving desulfurizing and smoke eliminating efficiency, and device for modifying investment is less, uses this device flue gas after treatment can reach the requirement of national environmental protection department.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, parts label is: 1. charging aperture, 2. desulphurization during combustion chamber, 3. the first dividing plate, 4. slag trap, 5. once desulfurization smoke elimination chamber, 6. chimney, 7. communicating pipe, 8. base, 9. water inlet pipe road junction, 10. outlet pipe road junction, 11. air inlets, 12. slag notches, 13. bodies of heater, the interlayer of 14. splendid attire water, 15. fire grates, 16. secondary desulfuration smoke elimination chambers, 17. second partition 18. outlet flues.
Detailed description of the invention
As shown in Figure 1, a kind of direct desulfurization smoke-removing boiler, comprise base 8, body of heater 13 is set on base, body of heater is provided with the interlayer 14 of splendid attire water, in body of heater, be provided with burner hearth, body of heater one side away from burner hearth is provided with chimney 6, burner hearth is provided with charging aperture 1 on corresponding furnace wall, air inlet 11 and slag notch 12, charging aperture 1, air inlet 11 and slag notch 12 are from top to bottom sequentially arranged on furnace wall, be provided with fire grate 15 at burner hearth bottom, described burner hearth is by desulphurization during combustion chamber 2, once desulfurization smoke elimination chamber 5 and secondary desulfuration smoke elimination chamber 16 form, be provided with the first dividing plate 3 at body of heater upper wall near the position of charging aperture, on the first dividing plate right side, second partition 17 is set, body of heater diapire between the first dividing plate and second partition tilts and is provided with slag trap 4, the gradient of slag trap and body of heater diapire is β, 90 ° of 0 ° of < β <, the left wall of body of heater, the first dividing plate, at the bottom of slag trap and body of heater, form desulphurization during combustion chamber 2, the first dividing plate, body of heater upper wall, second partition and slag trap form the first smoke elimination chamber, the first dividing plate, second partition and slag trap are sandwich plate, and the first dividing plate, the interlayer of second partition and slag trap is communicated with furnace sandwich, in the body of heater on second partition right side, be provided with communicating pipe 7, before communicating pipe and body of heater, the interlayer of rear wall is communicated with.
Be evenly distributed on described communicating pipe in the body of heater on second partition right side, from the first desulfurizing and smoke eliminating chamber, flue gas out, through communicating pipe, reaches the object that secondary desulfuration eliminates smoke.
The level height of the outlet flue 18 between described slag trap and the first dividing plate between charging aperture lower end and air inlet upper end, convenient fuel completing combustion.
The area of described desulphurization during combustion chamber is less than 1/3 of whole body of heater area, strengthens the area of smoke elimination chamber, makes the pernicious gases such as sulfur dioxide can be to greatest extent in the indoor elimination that eliminates smoke.
The course of work of the present utility model: fuel is added in desulphurization during combustion chamber 2 by charging aperture 1, light a fire from air inlet 11, after igniting, fuel takes fire, the flue gas producing arrives the first smoke elimination chamber, under the effect of the secret slag trap of second partition, the heat of flue gas and the first dividing plate, body of heater upper wall, second partition and slag trap carry out heat exchange, reach the object of desulfurizing and smoke eliminating for the first time.Flue gas after once desulfurization eliminates smoke enters the second smoke elimination chamber, under second partition, body of heater upper wall, the effect of communicating pipe, carries out desulfurizing and smoke eliminating for the second time, finally discharges by chimney 6.Through the first flue gas disappearing after desulfurizing and smoke eliminating, the second twice smoke elimination in desulfurizing and smoke eliminating chamber, its pernicious gas is eliminated to greatest extent, has reduced environmental pollution like this.
