Description
Technical field
The present invention relates to a kind of integrated sludge drying and incinerating machines, belong to evaporation drying equipment technical field.
Background technology
China reforms and opens up to the outside world two during the last ten years, the society with China and rapid development of economy, city size and population
Increase, thriving life is brought to city, still, environmental problem also becomes increasingly conspicuous, especially the deterioration of Urban Water Environment,
The physical and mental health of the people is not only affected, and exacerbates the shortage of water resource, oneself is through as urban sustainable development
Serious restraining factors.
Sewage is after the processing of various different process, after water outlet has reached the discharge standard of national regulation, sewage disposal
The sludge generated in journey still contains the nutriments such as a large amount of organic substance and abundant nitrogen phosphorus, is such as not added with and stablizes processing and appoint
Meaning is discharged into water body, and the oxygen in a large amount of consumption water bodys is caused water quality to deteriorate, sternly by the organic matter and ammonia, nitrogen in sludge
The existence of ghost image Xiangshui County biology, the nutriment in sludge can cause the eutrophication of water body, promote the pernicious breeding of algae, cause
The red tide and green tide phenomenon of water body not only deteriorate urban water resource water quality, influence domestic water and industrial or agricultural water, will also make fishing
Industry yield declines, and causes huge economic losses；If used agriculturally, the heavy metal in sludge can contaminated soil and crop；
The factor for also endangering human health in sludge containing pathogenic bacteria, parasitic ovum etc., deals with improperly, can cause the propagation of disease.This
Just serious secondary pollution is caused to environment.Therefore sludge must be handled before carrying out final disposal, reach decrement
Change, stabilize, innoxious, recycling purpose.
The advantage of sludge incineration disposition is rapidly and largely sludge to be made to reach minimizing.In municipal sludge
Containing a large amount of organic matter and a certain amount of cellulose wood quality, suitable detonator, catalyst, raising agent and sulphur-fixing agent are mixed
Equal additives can carry out burning disposal.But the drawbacks of this disposal options, is, sludge must assure that relatively low aqueous
Rate, even and if municipal sludge moisture content after dehydration is still relatively high, be 75% ~ 80% or so.Such sludge is being burned
It when processing, to maintain ignition temperature at 750 DEG C ~ 850 DEG C or more, need that a large amount of fuel auxiliary combustion is added, and be easy production
Raw a large amount of bioxin, while the heavy metal in sludge can also be diffused out with flue dust, and secondary pollution is caused to environment.If this
A little aspects are solved very well, and sludge incineration can generate and provide the energy.
Sludge drying bed is a kind of relatively old, easier mud dewatering method.By three kinds of sides such as permeating, evaporate and exclude
Formula removes moisture.But as the property of sludge is different from local meteorological condition, by permeating, evaporating and excluding removed moisture
Ratio is also different.Sludge drying bed technology investment expense is low；It takes up a large area, sanitary condition is poor；Disappear suitable for small sewage treatment plant
Change sludge.
To estimate from the development trend of world's Treatment of Sludge, being combined with recycling sludge is disposed in the processing of sewage sludge,
The final outlet of city sewage and sludge will be become.The development of Treatment of Sludge must be strided forward to innoxious, recycling direction.I
State region is wide, and nature, economy, staff condition are different, and the sludge that sewage treatment plant generates carries out existing for final disposal
Problem is not quite similar, and therefore, the final disposal of sludge cannot use unified pattern, be according to the compositional classification and combination sheet of sludge
The specific truth in area selects the approach of final disposal.It is complete to develop technologically advanced, economical and efficient domestic Treatment of Sludge
Equipment changes and largely uses import equipment, the situation for causing Treatment of Sludge investment cost to remain high at present；Actively carry out sludge
Resource analysis etc. is to solve current and the handling problems of China's city sewage and sludge processing from now on effective ways.
Invention content
Present invention mainly solves the technical issues of：A large amount of bioxin are easy tod produce when being disposed for sludge incineration, to environment
It pollutes, occupation area of equipment is big, it has not been convenient to which the problem of operating, the present invention provides a kind of integrated sludge drying and incinerating machines.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention：
A kind of integrated sludge drying and incinerating machine, including babinet, spiral push device and motor, babinet top offer
Exhanst gas outlet, babinet right side opening are equipped with mud entrance, and babinet top half is mud drying chamber, and lower half portion is burned for mud
Chamber, mud drying chamber are separated between mud burns chamber by heat-conducting plate, and mud burns chamber right side opening and is equipped with sludge outlet, described
Spiral push device be arranged in the mud drying chamber of babinet top half, spiral push device is fixed by rotary shaft, rotation
Shaft is connected by V belt translation in motor, and mud scraper plate is provided on the outside of spiral push device.A kind of sludge drying and incinerating one
The application process of body machine is：Mud is dried before burning and mud is first burned into intracavitary lights flame, mud is from mud entrance
It into the mud drying chamber of babinet top half, is pushed to the left through spiral push device, mud burns the flame warp in intracavitary portion
Heat-conducting plate conveys heat to mud drying chamber, and mud is dried in the heat of conveying, and the mud of preliminarily dried is through spiral pushing
Device conveys to the left, later falls into mud and burns in chamber, and mud burns in mud burns chamber, and the smoke backflow for burning generation arrives
In mud drying chamber, the mud inside mud drying chamber is dried using fume afterheat, is then discharged through exhanst gas outlet, become silted up
The lime-ash that mud generates after burning then burns the lime-ash on the right side of chamber through mud and exports discharge.
The babinet is at U-shaped.
The mud scraper plate is made of silicone rubber material.
The beneficial effects of the invention are as follows：
（1）A kind of U-shaped babinet is devised in the present invention, U-shaped babinet top half is mud drying chamber, and lower half portion is burnt for mud
Chamber is burnt, centre is separated using heat-conducting plate, makes mud when being burned in burning chamber using this design, a part of heat can pass through
Heat-conducting plate is transmitted in mud drying chamber, and mud is dried using the heat of transmission, effectively increases the utilization rate of heat,
Burning the flue gas generated in chamber simultaneously can be transported in mud drying chamber by U-shaped babinet, using the waste heat of flue gas to mud
It is dried, effectively improves the rate and quality of mud drying, flue gas flows in mud drying chamber to utilize mud to cigarette
Gas is filtered, and by filterings such as lime-ash in flue gas, so that flue gas is reached discharge standard, is good for the environment operation.
U-shaped babinet, U-shaped babinet is used to reduce integrated sludge drying and incinerating machine using up-down structure design in the present invention
Floor space convenient for building large-scale mud drying and incinerating factory, while facilitating management.
Mud is conveyed using spiral push device in the present invention, helix transporting device can be efficiently by mud from dextrad
Left conveying, while being stirred to mud makes mud be heated evenly in drying chamber, raising dry mass, outside helix transporting device
Side is additionally provided with mud scraper plate, and mud scraper plate follows spiral push device to rotate, and mud is effectively prevent to be bonded in mud drying chamber
Inner wall on.
