The sludge drying device is characterized in that a mixer for mixing the dry sludge powder and the waste grease is arranged at the preceding stage of the burner, a pre-heater is arranged between the mixer and the burner, the hot blast stove is arranged between the burner and the dryer, the burner is respectively connected with the hot blast stove and the dry distillation machine through pipelines, and the hot blast stove is connected with the dry distillation machine through a pipeline. According to the sludge drying device, the mixture of the waste grease and the dry sludge powder is used as the fuel, so that waste is changed into valuable; and waste heat produced in the drying and dry distillation processes is recycled, so that heat consumption is reduced, the energy consumption of materials is reduced, and practical equipment is provided for resourceful treatment of urban biological sludge.
Description
Technical field
The utility model relates to a kind of environmental protection equipment of sludge treatment, and particularly a kind of waste oil mixes the sludge drying mechanism of making fuel with sludge dry powder, belongs to the environmentfriendly products technical field.
Background technology
Quickening along with the city 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, this has become a kind of enforceable environmental protective measure.Contain a large amount of mud in sewage and the trade effluent, report the treatment process of this type of biochemical sludge is all existing.At present there are landfill method, composting process, combustion method in China and make charcoal method etc. the biochemical sludge treatment process, but mainly is to be main with landfill method, and the required processing costs of landfill method is lower, and is simple, but floor space is big, the risk that also exists source of pollution to shift.There are some researches show that closely the development of polluting treatment technology just develops a drying stage that important stage is a mud of sludge treatment environmental protection resource utilization systematic procedure toward the direction of sludge treatment environmental protection resource utilization; Its required drying plant has strict requirement; Should rapid drying, improve thermo-efficiency, again can save energy; Reduce processing costs, also will prevent the secondary pollution that treating processes produces.Adopting waste oil to mix with sludge dry powder as fuel is a kind of useful trial of sludge-drying.
Summary of the invention
The utility model provides a kind of waste oil to mix the sludge drying mechanism of making fuel with sludge dry powder; Waste oil in its utilization life and the production mixes with sludge dry powder by a certain percentage makes fuel; Biochemical sludge is carried out drying and carbonization to be handled; The sludge treatment effect is remarkable, reaches to utilize waste fuel to carry out the purpose of sludge treatment resource utilization.
The technical scheme that the utility model is taked:
A kind of waste oil mixes the sludge drying mechanism of making fuel with sludge dry powder; Comprise burner, hotblast stove, moisture eliminator and destructive distillation machine; It is provided with waste oil and sludge dry powder blended mixing tank in the burner prime, between mixing tank and burner, is provided with preheater, between burner and moisture eliminator, is provided with hotblast stove; Burner is connected with the destructive distillation machine with hotblast stove respectively through pipeline, and hotblast stove is connected with the destructive distillation machine through pipeline.
Described burner has air compressor machine through pipe connection, provides burning required air through air compressor machine to burner.
The granularity of described sludge dry powder is 200～500 orders, water cut≤10% (weight percentage).
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: this sludge drying mechanism adopts three grades of sludge driers and external-heating revolving destructive distillation machine that higher thermo-efficiency is all arranged, and the drying sludge destructive distillation is effective; In burning, adopt waste oil and sludge dry powder propellant combination; Both utilized the calorific value of waste oil and sludge dry powder; Turn waste into wealth; The waste heat that also effectively utilizes in the drying process simultaneously carries out second stage employ, has reduced the energy consumption of hear rate and material, is that the city biochemical sludge is handled the visual plant in the environmental protection resource utilization system.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The contrast accompanying drawing is explained its structure.
In Fig. 1; The waste oil 2 of collecting (for example hogwash fat) is sent into mixing tank 3 through oil pump 4 after treatment; Sludge dry powder behind the drying sludge 1 is reached granularity 200～500 orders (water cut is less than 10%) through pulverizing send into mixing tank 3 through mud powder inlet; Waste oil and sludge dry powder thorough mixing by a certain percentage in mixing tank; Send into preheater 5 through the discharge port of mixing tank then and carry out preheating, waste oil after preheating and sludge dry powder mixture are sent in the burner 6 through pipeline and are burnt.Burning provides air through air compressor machine 7.The high-temperature flue gas that is produced during burning (500～700 a ℃) part gets into hotblast stove 8 through pipeline and then supplies with moisture eliminator 10 sludge-dryings and make thermal source, and another part gets in the destructive distillation machine 11 through pipeline and for destructive distillation thermal source is provided.Used moisture eliminator is three grades of sludge driers, and it is a cylindrical structure, and tube in the big jacket casing overlaps little tube again, and mud different steps in tube contacts with flue gas, and in different steps different exhaust gas volumns is provided, and heat is fully used.
The inflammable gas of from the destructive distillation machine, discharging is sent Combustion of Hot Air Furnace back to through blower fan, carries out secondary thermal cycling utilization; The high-temperature flue gas that produces during destructive distillation (400～500 ℃) is sent moisture eliminator back to and is also carried out secondary thermal cycling utilization, has improved hot utilization ratio effectively.
The biochemical sludge 9 of collecting from the various places, city gets into moisture eliminator after pre-treatment dry; Be admitted to the destructive distillation of destructive distillation machine behind the drying sludge; Generation inflammable gas and high-temperature flue gas are all done secondary thermal cycling utilization during destructive distillation, then produce charcoal 12 finished products of reproducible utilization after the mud destructive distillation.
