Description
Technical field
The utility model relates to a kind of sludge treatment device.Specifically, be that mud is carried out the sludge carbonization stove that usefulness is handled in charing, be particularly useful for the mud on-the-spot disposal in the middle or small sewage treatment.
Background technology
Along with quickening of urbanization process, the generation of sewage increases year by year.For reducing the pollution of sewage to environment, country and enterprise have dropped into a large amount of financial resources, have set up a lot of sewage works and have come municipal effluent is carried out purifying treatment.And sewage work can produce a large amount of mud again in to sewage treatment process.Mud is the product of a lot of contamination build-up, as mud not being handled, can bring secondary pollution again to environment.Therefore, must handle the mud that sewage work produces.
At present, the processing to sewage plant sludge mainly contains following two kinds.A kind of is to burn after mud is transported to the power station and coal is mixed, and another kind is as green fertilizers for potted flowers material.The former need transport to the power station with mud and burn, and transportation and burning expense are higher, make processing cost higher.If phenomenon can appear disorderly falling in poor management unavoidably in transportation.The latter is used as green fertilizers for potted flowers material with mud.Owing to contain a large amount of pollutents in the mud,,, still can bring pollution to environment through rainwash as behind the green fertilizers for potted flowers material.
The utility model content
The problem that the utility model will solve provides a kind of sludge carbonization stove.Adopt this sludge carbonization stove to come mud is carried out on-the-spot disposal, can reduce processing cost, thoroughly avoid the pollution that environment is brought.
For addressing the above problem, take following technical scheme:
The sludge carbonization stove characteristics of the utility model are to comprise body of heater, and mud import and air outlet are arranged at the body of heater top, and bottom of furnace body has inlet mouth.Last groove and following groove are arranged in the body of heater, and the notch of last groove and following groove has spacing between last groove and following groove all up.In last groove and the following groove whisking appliance is arranged all, this whisking appliance contains rotating shaft, and blade is arranged in the rotating shaft, and the rotating shaft two ends all are rotatable shape and match with the two ends cell wall of respective grooves.Rotating shaft one end all stretches out outside body of heater, and said external part links to each other with an actuating unit.On at the bottom of bottom land one end slot of last groove mud mouth is arranged, bottom land one end of following groove has ash output hole, and the said mud mouth of going up groove is in the notch top of groove down, said ash output hole be in away from the following groove bottom land of mud mouth and ash output hole stretch out under bottom of furnace body.On the furnace wall between last groove and following groove burner port is arranged, with the corresponding body of heater of this burner port outside burner is arranged all, the crater of burner is communicated with burner port respectively.
Wherein, there is the dry mud feed bin of crossing in said mud ingress, and the feed bin top and the bottom have import and outlet respectively; Outlet on the feed bin links to each other with the mud import at body of heater top through auger.
There are gas blower, oxygen-rich air producer and oxygen cylinder in the bottom of furnace body outside, and the outlet of gas blower is communicated with inlet mouth; The import of gas blower is communicated with the outlet of oxygen-rich air producer.Be processed with atmosphere import and oxygen inlet on the oxygen-rich air producer, oxygen inlet links to each other with the outlet of oxygen cylinder.
There is induced draft fan at place, said air outlet, and the import of induced draft fan communicates with said air outlet, and there is high temperature catalyst deodorizer in the exit of induced draft fan.
Take such scheme, have the following advantages:
Can be found out that by such scheme because the sludge carbonization stove of the utility model comprises body of heater, the body of heater top is processed with mud import and air outlet, bottom of furnace body is processed with inlet mouth.Be provided with groove and following groove in the body of heater, between last groove and following groove spacing arranged.Be provided with whisking appliance in last groove and the following groove, rotating shaft one end of whisking appliance all stretches out outside body of heater and with an actuating unit and links to each other.Be processed with mud mouth at the bottom of bottom land one end slot of last groove, bottom land one end of following groove is processed with ash output hole.Said mud mouth is in the down notch top of groove, said ash output hole be in away from the following groove bottom land of the mud mouth of last groove and ash output hole stretch out under bottom of furnace body.All be processed with burner port on the relative furnace wall between last groove and following groove, be provided with burner with the corresponding body of heater of this burner port outside, the crater of burner is communicated with corresponding burner port respectively.During work; At first through burner the body of heater inner chamber being carried out flame heats up; When treating that cavity temperature is raised to 300 ~ 800 ℃ in the body of heater, when closing burner, the worm conveyor of establishing through other makes and carries out the dry mud of crossing through last process and send into groove through the mud import; In continuous stirring and progradation, mud is by finish-drying.Subsequently, fallen into down in the groove by the mud mouth of the mud of finish-drying from last groove.Produce spontaneous combustion and send calorific value after the continuation of the sludge-drying of groove heats up under getting into, in continuous stirring and progradation, fully fire the ash of charring, at last from the ash output hole discharge of groove down.The calorific value that is produced by the mud spontaneous combustion comes the intravital temperature of supplementary furnace, and the interior drying sludge of groove carries out smoothly in the maintenance.When cavity temperature in the body of heater descends and is lower than 300 ℃, restart a burner body of heater inner chamber is carried out the flame intensification, make furnace temperature maintain 300 ~ 800 ℃ all the time, guarantee that the charing processing of mud is carried out smoothly.Because the charring furnace of the utility model is applicable to medium and small sewage work; Can be used as the indispensable equipment of WWT; Make that mud that sewage work produces can on-the-spot disposal, and in the background technology mud is transported to the mode of burning after power station and coal mix and compare, need not transport; Not only can reduce processing cost greatly, also can avoid the disorderly generation of phenomenon in the transportation.In addition, owing to make sludge carbonization, can avoid utilizing mud to bring situation about polluting once more to take place to environment as green fertilizers for potted flowers material through the sludge carbonization stove of the utility model.
