A kind of cow dung burning disposal reuse technology for vaccary, the process flow of cow dung are
The untreated excrement of step 1 is separated by solid-liquid separation：Cattle farm cow dung is transported by cow dung transport vehicle into dosing chamber, ox
Excrement is mixed with the waste water uniform stirring in wastewater disposal basin, and cow dung is delivered in solid-liquid separating equipment by latent dirty cutting pump and carries out solid-liquid
Separation；Dry cow dung after separation of solid and liquid is transported to argol canopy by screw conveyor, and waste water is delivered in wastewater disposal basin and waits at outward transport
It sets；
Solid manure after step 2 separation enters argol canopy, excrement drier and is delivered at fluidized bed incinerator burning
Reason：Excrement in argol canopy is transported to excrement drier by screw conveyor, and is helped to waste heat boiler offer by air-introduced machine
Combustion air avoids air pollution caused by stench；Vapor in excrement drier is provided by waste heat boiler, the argol after drying
Entered in fluidized bed incinerator by ribbon conveyer, the steam that dry excrement generates is after the effect of subcooler, Waste
Gas returns in waste heat boiler, and condensate liquid is discharged into wastewater disposal basin and waits for outward transport disposition；
The sand and ash generated after step 3 processing respectively enters sand bin and storage hopper carries out reuse or outward transport disposition：It uses
Place rubbish as fluidized bed incinerator be equipped with auxiliary fuel carry out burning disposal, place waste deposit in garbage storing box,
It is sent to fluidized bed incinerator through constant feeder, heavy oil is stored in oil drum as the auxiliary fuel of another fluidized bed incinerator
In, through gas flowmeter read waste heat boiler flue data so that control oil pump extraction heavy oil via flowmeter into becoming a mandarin
Fluidized-bed incineration stove；Residue after being burned through fluidized bed incinerator enters in sand-lime separator, through the separation of sand-lime separator
Sand and ash respectively enter sand bin and storage hopper, and the sand in sand bin can be with reuse pad field, and the ash in storage hopper then waits for outward transport
Disposition；
The exhaust gas that step 4 is burned enters waste heat boiler and is deacidified, dedusting, exchanges heat and further carry out at slag and effluent
Reason：The flue gas of fluidized bed incinerator enters waste heat boiler, and waste heat boiler also provides combustion air for fluidized bed incinerator；Waste heat
The vapor part that boiler generates is delivered to excrement drier and is dried for excrement, and the combustion air after another part preheating is sent

Spray scrubber in using calcium hydroxide as desulfurizing agent, tail gas be respectively adopted cyclone dust collectors and bag filter progress two level
Dust removal process, bag filter is interior to use active carbon filler.
4. a kind of cow dung burning disposal reuse technology for vaccary according to claim 2, it is characterised in that：It is described
Fluidized bed incinerator to be used as auxiliary fuel, place house refuse using place house refuse and heavy oil be all additions, heavy oil
It does not add generally, when exhaust gas volumn is less than the 70% of design value, starts to add heavy oil, heavy oil additive amount is the 10%- of inlet amount
20%；When exhaust gas volumn reaches design value, stop addition heavy oil.
5. a kind of cow dung burning disposal reuse technology for vaccary according to claim 2, it is characterised in that：It is described
The air source of waste heat boiler have three classes, the respectively flue gas of fluidized bed incinerator, account for 30-35%；The Waste of excrement drier
Gas accounts for 50-55%；The combustion air of argol canopy, accounts for 10-20%；Supplying gas for the waste heat boiler has three classes, respectively send to
The combustion air of fluidized bed incinerator, accounts for 15-25%；It send to the vapor of excrement drier, accounts for 35-45%；It is supplied for place
Warm excess heat, 30-50%.
6. a kind of cow dung burning disposal reuse technology for vaccary according to claim 2, it is characterised in that：It is described
Oil pump be the explosion-proof self-priming centrifugal oil pump of CYZ-A types, flow 3.2-500m3/h, lift 12-80m；Described is latent
Dirty cutting pump is WQK type cutting-type sewage/waste electrical submersible pumps, and medium is averaged severe no more than 500 kilograms/every cubic metre；Institute
The quantitative elevator pump stated is diaphragm metering pump；The flowmeter for liquids and gases be respectively adopted ultrasonic flowmeter and
Thermal type gas quality flow meter；The air-introduced machine is 4-72 type centrifugal fans, and flow is 991~221730 m3/h,
Total head is 196~3195Pa.
