Abstract
The utility model relates to a novel flying ash processing device after refuse incineration, which comprises a flying ash tanker, an ash storage warehouse, a measurement device, a pneumatic conveying warehouse and a flying ash injection device. The flying ash tanker is connected with the ash storage warehouse through a warehousing pipeline; the lower end of the ash storage warehouse is connected with the measurement device through a pipeline; the lower end of the measurement device is connected with the pneumatic conveying warehouse through a pipeline; and the pneumatic conveying warehouse is connected with the flying ash injection device mounted in the kiln head of a rotary kiln through a conveying pipeline. The novel flying ash processing device is characterized in that because the flying ash injection device is arranged in the kiln head, the high temperature and the alkaline atmosphere of the cement kiln can be fully utilized to effectively ensure that extremely poisonous or injurious dioxins in flying ash are completely decomposed into water, carbon dioxide and other matters which are harmless to environment, so that the innocent disposal of the flying ash is ensured; and when the flying ash is burnt in the kiln, heavy metal in the flying ash can be solidified by cement to prevent extraction and finally can enter cement products, so that wastes are utilized, and no secondary pollution is generated. The novel flying ash processing device has the advantages of novel and special structure, simplicity, practical use, continuous process, high automation, safety and reliability.
Description
Technical field
The utility model relates to the flying dust treatment unit after a kind of waste incineration.
Background technology

Summary of the invention
The purpose of this utility model is to provide a kind of new treatment unit of flying dust, be the equipment that matches with a kind of new treatment process of flying dust, it mainly is the reluctant problem of flying dust after the solution waste incineration, it can spray into the flying dust after burning in the cement rotary kiln by this treatment unit, the mode that promptly adopts high temperature incineration and cement solidification to combine, utilize the high temperature characteristics of cement kiln that De dioxin in the flying dust is thoroughly decomposed, heavy metal is cured to a part that becomes cement in the cement lattice, reach the purpose of the harmless treatment of flying dust, both the flying dust utilization of waste material can be made, second environmental pollution can be reduced again.
The purpose of this utility model is realized by following technical scheme.Flying dust treatment unit of the present invention comprises flying dust tank car, ash-storing bin, measuring apparatus, air conveying storehouse and flying dust jetting device, the flying dust tank car links to each other with ash-storing bin by the pipeline that puts in storage, the ash-storing bin lower end links to each other with measuring apparatus by pipeline, the measuring apparatus lower end links to each other with air conveying storehouse by pipeline, and air conveying storehouse links to each other with the flying dust jetting device by transport pipe.
The self-contained vacuum pressure of described flying dust tank car.
Described measuring apparatus can adopt weigher to control the blanking amount of flying dust, grasps the disposal amount of regulating flying dust by the kiln condition in the actually operating, guarantees that the flying dust disposal can not make manufacture of cement be interfered.
Described flying dust jetting device is installed in rotary kiln end, when the flying dust drop point that sprays into apart from the distance of kiln hood greater than 15 meters, and spray into when a little being located at kiln hood, can guarantee the harmlessness disposing of flying dust.
Described flying dust jetting device can be burner or spray gun device.
Described ash-storing bin upper end links to each other with bag collector through blanking device by pipeline.
The utility model has the advantages that:
1, the flying dust jetting device is located at the cement kiln kiln hood, make full use of the high temperature of cement kiln, alkaline atmosphere, can effectively hypertoxic objectionable impurities dioxin in the flying dust be resolved into fully materials such as the water of environmental sound and carbonic acid gas, guarantee the harmless treatment of flying dust.
2, flying dust burns in kiln, can not separate out with the heavy metal in the flying dust by cement solidification, enters cement products at last, and both utilization of waste material do not have secondary pollution again.
3, the novel structure uniqueness is simple and practical; Process is continuous, automatic, safe and reliable.
Description of drawings
The utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Fig. 1 is a kind of new treatment unit structural representation of flying dust.
Among the figure: 1. flying dust tank car, the pipeline that 2. puts in storage, 3. ash-storing bin, 4. measuring apparatus, 5. air conveying storehouse, 6. transport pipe, 7. bag collector, 8. flying dust jetting device, 9. rotary kiln.
Wherein: arrow is represented by gas blower high pressure gas to be blown into air conveying storehouse.
Embodiment
The new treatment unit of the described a kind of flying dust of present embodiment, as shown in Figure 1, it comprises flying dust tank car 1, ash-storing bin 3, measuring apparatus 4, air conveying storehouse 5 and flying dust jetting device 8, flying dust tank car 1 is connected with ash-storing bin 3 by the pipeline 2 that puts in storage, ash-storing bin 3 lower ends are connected with measuring apparatus 4 by pipeline, measuring apparatus 4 lower ends are connected with air conveying storehouse 5 by pipeline, and air conveying storehouse 5 is connected with flying dust jetting device 8 by transport pipe 6.
Described flying dust tank car 1 self-contained vacuum pressure.
