Knot, drying.Mud granule after sintering, drying is delivered to designated position by discharging mechanism 140.
Entered by the high-temperature flue gas that the air outlet of rotary kiln 110 is discharged and carries out electrostatic precipitation in electrostatic dust removal mechanism 210, it is dirty
Mud dust is trapped in electrostatic dust removal mechanism 210, and a part of high-temperature flue gas, which can enter in rotary kiln 110, continues as rotary kiln
110 improve heat, and due to containing high temperature heat in flue gas, which enters rotary kiln device 100 as Secondary Air, due to
The oxygen content of the flue gas of the part is low, therefore can inhibit the generation of nitrogen oxides, while the partial fume may be rotation
The sintering of solid waste in kiln device 100 and/or dry offer partial heat energy, can be effectively reduced the consumption of fuel, reduce
Production cost.Another part high-temperature flue gas is then successively handled by desulfurization mechanism 220, electric defogging mechanism 230, last clean
Exhaust gas pass through chimney outlet.
Sewage treatment is entered by the sewage that electrostatic dust removal mechanism 210, desulfurization mechanism 220 and electric defogging mechanism 230 are discharged
In the sludge coagulating sedimentation mechanism 310 of device 300, sewage sequentially enters denitrogenation mechanism 320 again, heavy metals removal mechanism 330, returns
With water storing mechanism, it is sequentially completed coagulation-denitrogenation-removing heavy metals-decoloration-effluent treating and reusing process, in sewage disposal process,
Sludge coagulating sedimentation mechanism 310 generates sludge, denitrogenation mechanism 320 generates sludge, heavy metals removal mechanism 330 generates sludge through dirt
Mud collecting mechanism 340 is collected, and processing can be transported outward by carrying out dehydration using sludge dewatering mechanism 350.Sewage after treatment may be used
Be recycled with being re-delivered in flue gas processing device 200 as process water, can effectively save water consumption, reduction is produced into
This.
Above-mentioned integral type solid waste drying and processing system 10 can be effectively reduced containing for discharge nitrogen oxides in effluent
Amount is to reduce environmental pollution.Integral type solid waste drying and processing system 10 of the invention is to solid waste such as sludge
When being dried, rotation furnace apparatus is used to be sintered and/or dry to solid waste to achieve the purpose that drying, revolving burner
The flue gas that device generates when solid waste is sintered and/or is dried then passes through gas outlet and enters electrostatic dust removal mechanism 210
Interior, electrostatic precipitation of the flue gas Jing Guo electrostatic dust removal mechanism 210 can remove most particle, and flue gas passes through flue gas processing device
200 desulfurization mechanism 220, electric defogging mechanism 230 carry out desulfurization and electric demisting, what the gas being discharged in atmosphere at this time contained
The content of sulfide and nitrogen oxides is less, effectively reduces the pollution to environment.The dirt being discharged from electrostatic dust removal mechanism 210
The sewage that the sewage and electric defogging mechanism 230 that water, desulfurization mechanism 220 are discharged are discharged is by sewage-treatment plant 300
Reason, reduces water pollution.The present invention can also handle related flue gas and Waste while handling sewage sludge solid waste object
Water reaches integral type processing intent, and treatment effeciency is high, high treating effect.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
