Description
Technical field
The utility model relates to flue-cured tobacco technical field, relates to a kind of energy-saving and emission-reduction bulk curing barn specifically.
Background technology
Will remove the moisture that water content reaches in the fresh tobacco leaves of 85% ~ 90% more than 90% in intensive baking room flue-cured tobacco process, tobacco flue-curing needs lot of energy.The loss of energy mainly hydrofuge heat waste, air flue emission heat waste, the heat radiation of barn structure heat waste, the incomplete heat waste of fuel combustion etc. in the process.Wherein hydrofuge heat waste accounts for the 30-50% of whole energy consumption, and in humid region, hydrofuge heat waste reaches more than 60%.The energy major part of this part is directly discharged in air, causes very large energy dissipation.Wherein the flue gas of heating furnace discharge generates suspended particulates dust, nitrogen oxide, SO
2in addition, a small amount of SO is also generated
3, owing to containing moisture content in flue gas, the SO of generation
3form sulfuric acid mist in moment, be discharged in air and form acid rain, cause environmental pollution.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, provides one effectively to fall
The discharge of low sulfide in flue gas, reduces the energy-saving and emission-reduction bulk curing barn of environmental pollution.
For solving the problem, the utility model is by the following technical solutions: a kind of energy-saving and emission-reduction bulk curing barn, comprise multiple barn body be arranged side by side, the outlet flue of each barn body is connected with smoke evacuation arm, by converging smoke pipeline connection between smoke evacuation arm, the top of barn body is fixedly connected with the purifying column for purifying smoke, and purifying column is communicated with remittance smoke pipeline.
Below further improvement of the utility model:
Described purifying column comprises tower body, tower body offers with converge that smoke pipeline is communicated with enter mouth, the position be positioned in tower body into the upper and lower both sides of mouth is respectively equipped with the shower for spraying purifying smoke liquid.
Further improvement:
Shower is connected with feed tube, feed tube is connected with clear water reserviors, the position on described feed tube between shower and clear water reserviors is connected with solution feed pump, and the bottom of described tower body is provided with liquid back pipe, and the one end away from tower body on liquid back pipe is connected with sedimentation basin.
Further improvement:
Position on described feed tube between solution feed pump and shower is provided with pressure gauge.
Further improvement:
Position on described feed tube between solution feed pump and clear water reserviors is connected with the liquid tank for splendid attire NaOH by pipeline.
Further improvement:
Described shower is provided with high-pressure atomization shower nozzle.
The utility model adopts technique scheme, and each heating furnace of the barn body flue gas of discharging collects by converging smoke pipeline, carries out sulphur removal, de-dirt, flue gas is discharged after purification under the effect of air-introduced machine in the purifying column importing barn top; Dust in purifying column and sulfide are sprayed by high-pressure atomization shower nozzle through water source endlessly that solution feed pump provides and power, cleaning, dust adsorption and sulfide enter in sedimentation basin through return duct, qualified discharge is again neutralized through NaOH after sulfide accumulation in sedimentation basin is a certain amount of, flue gas is after udst separation, and purifying column exhaust opening can't see smoke evacuation thing.
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
