Description
Technical field
The invention belongs to field of solid waste treating technology is and in particular to a kind of municipal sludge depth drying gasifying device.
Background technology
Municipal sludge typically refers to municipal sewage plant（Sometimes also include waterworks）Produce during processing sewage
Raw solid precipitation thing, complicated component, in addition to containing large quantity of moisture, also contains various heavy, organic pollution, the micro- life of cause of disease
The harmful substance such as thing and parasitic ovum, therefore, if do not carried out harmless treatment, can cause serious secondary pollution to environment.
In Urbanization in China quickening, urban population sharply increases, country puts into ever-increasing pushing away to environmental protection cause
Under dynamic, the construction of sewage treatment plant gets more and more, and the ability of water pollution control continues to increase, and sludge yield also gets more and more, according to
China Environmental Science Research Institute calculates, 2012, and China's each municipal sewage plant year sewage treatment capacity is about 46,200,000,000 tons,
The wet mud (moisture content 80%) producing reaches more than 4,600 ten thousand tons, accounts for more than the 5% of China's year total solid waste discharge amount.According to
" 12 " planning calculates, and China's cities and towns wet mud yield is up to 53,400,000 tons/year.
Municipal sludge is the inevitable outcome of sewage treatment plant and sewage disposal.Enter ring without the appropriate mud disposed that processes
Behind border, bring secondary pollution directly to water body and air.The main Environmental Problems existing are as follows：
（1）Moisture percentage in sewage sludge is high.Non- dewatered sludge moisture content is more than 90%, and preliminary hydro-extraction moisture percentage in sewage sludge is also up to 80%, causes
Cost of transportation is high, stack area big, pressing waste landfill yard storage capacity, blocking garbage filter liquid pipe the problems such as；
（2）Bacteria breed.Not only cause visual pollution, and provide place for growing of other harmful organisms；
（3）Atmospheric pollution.Mud be deposited in outdoor give out foul smell and abnormal flavour, Exposure to Sunlight wind blows, and contaminant particle can cause air
Pollution；
（4）Polluted-water.Soak through water, dissolve, pollutant flow into river course, meeting polluted surface water with sewage, enter subsoil water；
（5）Containing heavy metal.If not being controlled by, then may contaminated land.
The target disposed that processes of mud is to realize the minimizing of mud, stabilisation and innoxious, reclaim simultaneously as far as possible and
Using the energy in mud and resource.The process rationally realizing mud on the premise of safe and environment-friendly and economic is disposed and comprehensive
Close and utilize, reach energy-saving and emission-reduction and the purpose developed a circular economy.
Specific resistance to filtration includes processing and disposes two stages, and Treatment of Sludge is mainly and mud is carried out with stabilisation, subtracts
Quantify and innoxious processing procedure, main methods have：Thickening, anaerobic digestion, aerobic fermentation, sludge heat drying,
Lime stabilization etc.；After sludge treatment refers to the process of process, mud is carried out dissolving final disposal, and main method of disposal has：Soil profit
Utilized, burned and cooperative disposal, landfill etc. with, building materials.The process of mud and disposal are inseparable from two, process at conduct
The preposition operation put, disposes as the final home to return to processing, both are indispensable, indivisible.But according to the demand disposed, remove
Outside Land_use change, the preposition operation of other disposal operations is corresponding to be all sludge heat drying handling process.Land_use change is for me
For state's mud high heavy metal present situation, hazardness is big, if so before China selects sludge treatment technique, be required for heat drying
Process.
Existing heat drying equipment shortcoming on the market：
Dehydration rate is low., under the conditions of rational economy and energy utilization are forthright, dewatering efficiency is low for existing sludge drier, produces
The final water content of product up to 40% about.
Efficiency of utilization is low.Existing sludge drier under the conditions of rational economy and energy utilization are forthright, diarrhea of heat type
Low with rate, comprehensive utilization ratio only has 55% about.
It is undesirable that single drying equipment is dried mud effect.Because drying sludge belongs to new field in China, there is no pin
Special equipment to drying sludge, many instruments that are dried using other industry when it is dried, but the high spy of mud combined water
Property determine it using other drying equipments effect of not having of drying.
Between each link of composite equipment, air-flow influences each other.According to external in existing sludge drier（Or replicate state
Outward）Composite equipment also has one seat, but contrasts this kind equipment it is found that this kind equipment air-flow does not have Discrete control,
There is not second particle distribution to mud, after mud granule is dried, surface shrinkage degree is big, and pellet moisture gradient is big, product density yet
Little, finished product can not accomplish maximum minimizing, using its finished product burning, dry distilling, makes the poor strong men that all seem such as activated carbon
Meaning, product moisture content is high, and subsequent treatment is caused with very big energy dissipation.
Content of the invention
In view of this, present invention is primarily targeted at providing a kind of municipal sludge depth drying gasifying device.

Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, and
It is not used in the restriction present invention.
The embodiment of the present invention provides a kind of municipal sludge depth drying gasifying device, as shown in figure 1, this device includes charging list
Unit 1, Free water drying unit 2, described dosage unit 1 is arranged on above Free water drying unit 2；Described dosage unit 1 includes
The ultrasonic plate of dog-house 101, arc 102, feeding screw 103, material cutting extrusion mechanism 104, described dog-house 101 lower section is logical
The ultrasonic plate 102 of road tube wall outer symmetrical two pieces of arcs of setting, setting feeding screw 103, described passage and thing in described passage
Material shear extrusion mechanism 104 connects；Described dog-house 101 is generally equipment and links place with a upper active section, should be sealing state,
Its size is related with equipment treating capacity, and its blade diameter length ratio is generally 1:1.5~1:Between 1.3, in case of special state also can be not limited to
Above-mentioned regulation, diameter d=114*, unit is mm, and it is x ton that wherein x represents treating capacity per hour.Due to contain in mud
Large quantity of moisture is fettered by activated sludge floc, zoogloea and cyton, is only removed energy consumption using dry mode too high,
First these constraint bodies are broken by the ultrasonic plate of arc 102, be the mode reaching peak efficiency using minimum energy, ultrasound wave
Power is advisable for 20 ~ 40kHz；Described feeding screw 103, on the one hand for steady transferring raw material；On the other hand after ultrasonic
By water release, what the moisture discharging was uneven is distributed in the middle of raw material constraint body, and described feeding screw 103 can be again
Moisture of distribution, such drying efficiency can improve.
