Embodiment
The invention will be further described below in conjunction with the accompanying drawings, but not as limitation of the present invention：A kind of mud cracking
Device, including fixed mount 1, pyrolysis oven 2 and combustion furnace 3, described pyrolysis oven 2 is arranged on fixed mount 1 to be connected with combustion furnace 3；
It is characterized in that：Described pyrolysis oven 2 includes being provided with silt on preheating chamber 4, hothouse 5 and cracking room 6, described preheating chamber 4
Mud feeding structure 7, fume emission mouth 8, dehydration catalyst conveying auger 9, screw conveying structure 10 and charging grid 11, it is described
Screw conveying structure 10 is provided with preheating chamber 4, top is provided with charging grid 11, charging grid 11 and is provided with mud charging
Structure 7 and fume emission mouthful 8, described catalyst for cracking conveying auger 9 are arranged on the right side of preheating chamber 4；Described preheating chamber 4 with
It is provided between hothouse 5 in charging grid 12, described hothouse 5 and is provided with scraper 13；The described left side of cracking room 6
Pernicious gas port 14 is set, and right side is connected by thermal conductive pipe 15 with combustion furnace 3, bottom is twisted with that can return field biomass conveying
Dragon 16 is connected；Described cracking room 6 on hothouse 5 with being evenly arranged with some temperature sense modules 17.Described mud enters
Material structure 7 is that some cylindrical holes are evenly arranged with funnel-form, described charging grid 11, mud feeding structure 7 and charging
Grid 11, which coordinates, disperses mud.The described conveying of dehydration catalyst conveying auger 9 lime, coal dust, with mud feeding structure 7 and
The cooperating of screw conveying structure 10, carries out sludge dewatering drying.It is evenly arranged with described charging grid 12 some rectangular
Shape groove, makes the formation mud block of the mud after dehydration；The inwall cooperating of described scraper 13 and hothouse 5.Described
The main body of thermal conductive pipe 15 is made up of refractory material, and lagging casing is provided with outside thermal conductive pipe 15.The described bottom of cracking room 6 is set
There is funnel-form cooling device for discharging 18 to be connected with field biomass conveying auger 16 can be returned.Described pernicious gas port 14 includes
Some pernicious gas enrichment pipelines 19 and discharge duct 20, described pernicious gas enrichment pipeline 19 are distributed on cracking room 6, with
Discharge duct 20 is connected.
During specific implementation：Mud is added pyrolysis oven by funnelform mud feeding structure, and mud passes through mud feeding structure
Path passage with charging grid synergy, mud is divided into the fritter of a fritter one.Then mud drops into helical feed
Spiral declines in structure, the drier such as dehydration catalyst conveying auger conveying lime, coal dust, the water content in reduction mud；In advance
The heat that hot stove is passed over by combustion furnace, tentatively preheats mud, and the flue gas of generation is discharged by fume emission mouthful.Then
Mud is entered in dry road by charging grid, the heat of drying oven by sludge dewatering and solidifying into original volume half mud cake,
But prevent mud cake to be scorched again, therefore temperature sense module is evenly arranged with outside drying oven, in-furnace temperature is detected in real time.Mud
Cake is easily sticked on drying oven inwall in the curing process, therefore is provided with scraper drying in road.Then mud cake enters
Into pyrolysis furnace, the temperature detecting module of cracking furnace wall detects cracking temperature in real time.Cracking reaction under high temperature can produce more
Flammable pernicious gas, it is therefore desirable to by be distributed on cracking body of heater on pernicious gas be enriched with pipeline pernicious gas is complete
After collection, removed by discharge duct to fixed mount external combustion burning-off.Mud clod by cracking becomes one piece of block and is rich in
The carbon mud of the nutriments such as phosphorus, nitrogen, by funnel-form cooling device for discharging, mechanism is cooled down, and is conveyed by that can return field biomass
Auger is transported.
The above embodiment of the present invention, is only to clearly demonstrate examples of the invention, but be not limited to this hair
Bright protection domain, all equivalent technical schemes fall within scope of the invention, and scope of patent protection of the invention should be by each
Item claim is limited.
