Abstract
The utility model provides a sludge drying device taking waste oil as fuels. The sludge drying device comprises a burner, a hot blast stove, a drier and a dry distillation machine, wherein a waste oil processor is arranged at the front stage of the burner and is connected with the burner through a pipeline and an oil pump; the burner is respectively connected with the hot blast stove and the dry distillation machine through the pipeline; and the hot blast stove is connected with the drier through the pipeline. The sludge drying device has the beneficial effects that the waste oil is adopted as the fuels, so that wastes can be changed into valuables; and meanwhile, waste heat in the dry distillation process is effectively utilized for hot circulation and secondary utilization, so that the heat loss as well as the energy consumption of materials is reduced, therefore, the sludge drying device is key equipment in a promising city biochemical sludge treatment system.
Description
Technical field
The utility model relates to a kind of sludge treatment environmental protection equipment, and particularly a kind of waste oil is made the sludge drying mechanism of fuel.
Background technology
Along with quickening of urbanization process; The Surroundings in Cities pollutes more and more serious; All must be as the sewage of one of urban pollution resource and trade effluent through handling, could discharge after reaching the standard of environmental administration, become a kind of enforceable environmental protective measure.Contain a large amount of mud in sewage and the trade effluent, the treatment measures of this type of biochemical sludge are all reported both at home and abroad to some extent.At present there are landfill method, composting process, combustion method in China and make charcoal method etc. method for sludge treatment, mainly is to be main with landfill method, and the required expense of landfill method is lower, and is simple, but floor space is big, the risk that exists source of pollution to shift.Closely have research to show, the development of sludge treating system just develops the drying stage that a significant process stage of sludge treatment environmental protection resource utilization process is a mud toward the direction of environmental protection resource utilization; Its required drying plant has strict requirement; Can rapid drying mud, raise the efficiency, again can save energy; The reduction expense also will prevent secondary pollution.Adopting waste oil to come sludge-drying as fuel is a kind of ground-breaking trial.
Summary of the invention
The utility model provides a kind of waste oil to make the sludge drying mechanism of fuel; It utilizes life and industry to go up the waste oil that produces and makes fuel; Mud is carried out drying, destructive distillation processing, and obvious processing effect utilizes waste oil to carry out the purpose of sludge treatment resource utilization thereby reach.
The technical scheme that the utility model is taked:
A kind of waste oil is made the sludge drying mechanism of fuel; Comprise burner, hotblast stove, moisture eliminator and destructive distillation machine; It is characterized in that being provided with the waste oil treater in the burner prime; The waste oil treater is connected with burner with oil pump through pipeline, and burner is connected with the destructive distillation machine with hotblast stove respectively through pipeline, and hotblast stove is connected with moisture eliminator through pipeline.
Being connected with air compressor machine on the burner of the utility model, is that waste oil burns in burner air is provided through air compressor machine; The destructive distillation machine is connected with hotblast stove through blower fan, the inflammable gas that produces during for the destructive distillation of hotblast stove loopback mud; The destructive distillation machine is connected with moisture eliminator through blower fan, the high-temperature flue gas that produces during for the destructive distillation of moisture eliminator loopback mud.
Described moisture eliminator is three grades of sludge driers, and the destructive distillation machine is an external-heating revolving destructive distillation machine.
The beneficial effect of the utility model: three grades of sludge driers of the main equipment of this sludge drying mechanism and external-heating revolving destructive distillation machine all have very high thermo-efficiency, and drying effect is good; In burner, adopt waste oil to make fuel, turn waste into wealth, this dry device effectively utilizes the waste heat in the drying and carbonization process simultaneously, has reduced thermal losses, has reduced the energy consumption of material, is one of key equipment in the biochemical sludge recycling treatment system of city.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The contrast accompanying drawing specifies its structure.
In Fig. 1; The waste oil 1 of collecting (for example hogwash fat) is handled in waste oil treater 2, becomes combustible waste oil, passes through the discharge port of waste oil treater then; To burner 4 internal combustion, burning provides under the air situation at air compressor machine 5 and accomplishes through oil pump 3 extractings.The high-temperature flue gas that is produced during burning (500～700 a ℃) part gets into hotblast stove 6 through pipeline and then supplies with moisture eliminator 9 sludge-dryings and make thermal source, and another part gets in the destructive distillation machine 10 through pipeline and for the mud destructive distillation thermal source is provided.Moisture eliminator is three grades of sludge driers, and it is a cylindrical structure, tube in the big jacket casing; Overlap little tube again; Mud different drying stages and flue gas in tube and provide different exhaust gas volumns at different drying stages successively by adverse current, following current, counter current contact, and heat is fully used.
The inflammable gas that the destructive distillation machine is discharged in the mud retort process is sent hotblast stove back to through blower fan 7, carries out secondary thermal cycling utilization; The high temperature cigarette that produces during destructive distillation (400 ℃) is sent moisture eliminator back to and is also carried out secondary thermal cycling utilization, has improved hot utilization ratio.
In this device, biochemical sludge 8 gets into moisture eliminator 9 after preheating, and mud gets into 10 destructive distillation of destructive distillation machine after drying, and inflammable gas that produces during destructive distillation and high-temperature flue gas are done secondary thermal cycling utilization, become the charcoal 11 of reproducible utilization through sludge through destructive distillation.
