High 2.5m, groove body length can be set according to mud handling capacity.Slot bottom arranges three ventilation ducts 35, and ventilation duct 35 is uniformly distributed,
Every 1.5m, ventilation duct 35 has multiple equally distributed ventilation holes, ensures uniformly to supply oxygen for heap body each several part, heap body is made fully to send out
Ferment.Centrifugal blower 36 is corresponded with fermentation tank 31, i.e., separate unit centrifugal blower 36 supplies single fermentation tank 31, with decentralised control
Composting fermentation process in each fermentation tank 31.The cell wall of fermentation tank 31 is provided with monitoring device placing groove, is inside disposed with temperature spy
Survey/oxygen monitoring device 37 for the on-line monitoring of material oxygen content and temperature, controls aeration quantity, and effective guarantee ferments always
At one's best, monitoring device placing groove can be evenly arranged according to the length of fermentation tank 31.Now in the art, usually by temperature
Detection/oxygen monitoring device 37 is directly inserted in fermentation tank 31 (i.e. in sludge), in practical application, turning over throwing every time will pull out
Out, as a preferred embodiment, the monitoring device for outputing suitable dimension size in embodiment at the cell wall of fermentation tank 31 is placed
Slot, and temperature sensing/oxygen monitoring device 37 is arranged in monitoring device mounting groove, sludge and temp probe contact/gas
By oxygen sensor, the digital signal that electric signal generates temperature/oxygen concentration through transmitter is generated, passes through conveying circuit in real time
It is stored by computer acquisition to capture card, and is shown simultaneously in display.32 preferred BACKHUS turners of turner, BACKHUS
Turner can make full use of oneself body advantage, clean out Crane Rail by track cleaning device, roller is variable speed, also may be used
It reverses, ground will not be encountered during turning.Using BACKHUS control systems, i.e. excess load track drive control system
System, can also automatically adjust operation intensity under event of overload.It, can be in unevenness with track cleaning device and mating flusher
, travelled on soft ground.ZL50 forklifts can be selected in loading machine 38, pass through diesel driven.
In screen house 4, mainly include screening machine 41, belt feeder 42.Compost passes through loading after fermented workshop 3 is handled
Machine 38 is transported to screen house 4.
Above each workshop is by functional regional division, and to prevent the tail gas in workshop excessive, which is also provided with deodorization
System mainly includes suspended hood 51, ventilation shaft 52, deodorization wind turbine 53 and biofilter 54.Suspended hood 51 is arranged in storage vehicle
Between 1, material mixing workshop 2, the top of fermentation plant 3, each suspended hood 51 is connected to the ventilation shaft 52 at top, then by deodorization wind turbine 53
It send to biofilter 54.Pass through the deodorization subsystem, material basic free from extraneous odour after everfermentation.
With reference to shown in Fig. 4, the specific workflow of wet mud compost is as follows:
Wet mud is poured onto the wet hopper dredger 12 being arranged in below earth's surface by sludge transport vehicle, and wet 12 top of hopper dredger is semi-closure
Half opening device, electric cabin door 11 is automatically closed after dumping, and is equipped with gas detecting instrument, for example, combustible gas alarming instrument.It is wet
Sludge enters wet hopper dredger 12 by the sieve plate 123 that wet 12 top of hopper dredger is set.It after storing, can be by being set at discharge port 124
14 conditioning of mud of flow control valve load, and pass through two screw pumps 15 and export wet mud, the wet mud of output is again
It is continuous, average rate, constant volume into the progress mixing treatment of material mixing workshop 2 by sludge transporting pipeline 13.
Wet mud enters batch mixer 21 through sludge inlet 211, and stalk is sent by belt feeder 22 to batch mixing after crusher in crushing
Machine stalk feed inlet 212, after the screened sieve of machine 41 of sludge composting product is expected, oversize is sent into the ripe of batch mixer 21 through belt feeder 23
Expect that reflux inlet 212 carries out mixing treatment, the mixed material after mixing treatment is exported by the discharge port 213 of batch mixer 21, gone out
High angle belt conveyer 33 is connect under material mouth 213,33 lower accepting water flat belt 34 of high angle belt conveyer, mixed material is by high angle belt conveyer 33 and water
Flat belt 34 is transmitted to fermentation plant 3 and ferments.
Fermentation plant turns over throwing mode using trough composting, using whole input and output material technique.Mixed material through belt feeder send to
The fermentation tank 31 of fermentation plant 3, through distributing device uniform distribution until groove body piles with.Using turning over, throwing supplies oxygen and pressure is logical during fermentation
The mode that wind combines supplies oxygen for fermentation, and forced ventilation, turner are realized by using the aerator of scattered supply in the fermentation phase
32 periodically carry out heap body to turn over throwing, ensure one day turning ability at least once.Specifically, daily charging is disposably placed in
One or more of one fermentation tank 31 fermentation unit, entire slot is not by the way of carrying out returning and throwing, in entire fermentation period
Into new material, wait once to discharge after the completion of fermenting.Turner 32 uses diesel oil as fuel, walks in the cell wall of fermentation tank 31
On, forward and reverse walking while, carries out turning over throwing, and throwing is turned over so as to fulfill shuttle.Turner 32 can set daily turning and throwing once,
The contact with air in a flash of throwing is turned over using material and realizes oxygenation, ensures to be turned over the uniform and abundant aeration of cast material,
The dead angle of sweathouse is avoided, improves the stability of compost.It is only oxygenated, is then inevitably led by turning over throwing in fermentation process
The most of the time is caused to there are problems that anaerobism, so as to cause stench and the environmental sanitation problem of mosquitos and flies, for oxygen is overcome to supply hypoxgia
The shortcomings that, in above process, referred to using forced ventilation in fermentation plant 3 by being supplied in fermentation plant 3 using scattered
Aerator come the shortcomings that further overcoming fermentation subsystem oxygen oxygen supply deficiency, by 31 bottom of fermentation tank along length side
To the ventilation duct 35 (can also be ventilation slot) of setting, supplied by centrifugal blower 36.Aerator uses temperature-oxygen
Intelligence control system controlled, the blow rate required of combining with fermentation time control centrifugal blower 36 and contains oxygen demand to heap body
Water carries out a degree of control, and it is at one's best always that fermentation is effectively ensured.
After fermentation, material is sent to screen house 4, screened machine by loading machine 38 less than 30% moisture content compost
Oversize after 41 screenings send to the clinker reflux inlet of batch mixer 21/stalk feed inlet 212 through belt feeder 23 and carries out back-mixing, sieve
Lower object makes packed organic fertilizer product by retrofit or directly does afforestation, Nutrition Soil use, realizes recycling sludge
With innoxious purpose.
In above process, the tail gas that each workshop generates in composting process is removed by deodorization subsystem, in storage workshop
1st, material mixing workshop 2, in fermentation plant 3, storage workshop 1, material mixing workshop 2, the deodorization air hose of fermentation plant 3 and removing for compost workshop
Smelly air hose is connected.The foul smell that compost generates is sent by deodorization wind turbine 53 to biology again after being adsorbed by suspended hood 51 through deodorization air hose 52
Filter tank 54 is filtered taste removal, with rear discharge up to standard.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
