Description
Technical field
The present invention relates to field of garbage disposal, in particular to a kind of mud drying device and method.
Background technique
In recent years, as the quickening and industrial and agricultural production of the increasingly serious and Urbanization Construction paces of environmental requirement are advised
Mould is promoted, the activated sludge of municipal sewage plant, the sludge (such as brewery sludge) of industrial production processing, farm biogas residue
And the yields such as excrement sludge increase year by year, these sludge moisture contents are up to 60-85%, and landfill waste soil, incinerating combustion value are low,
Processing is difficult.Only up to 60,000,000 tons or more of the annual whole nation of municipal sludge.It such as cannot quickly dispose, dissolve, it will cause secondary
How pollution preferably handles sludge and generates as puzzlement sewage treatment plant, sludge as garbage loading embeading place is gradually saturated
One problem of enterprise and local government.
Sludge is mainly the product after sewage treatment, is one kind by organic debris, microorganism, inorganic particle, colloid etc.
Composition and its complicated heterogeneous body.Its key property is that moisture content is high (can be up to 99% or more), high organic content
(the especially sludge of printing and dyeing, papermaking generation), dry base heat value reaches as high as 14651kJ/kg in 8372kJ/kg~12558kJ/kg,
It is easy to degenerate smelly and contains the poisonous and harmful substances such as a large amount of heavy metal, germ, while its particle is compared with thin, specific gravity is small, is in glue
Shape liquid is concentrated thing between a solid and a liquid, pump can be used and transported, but it is difficult to carry out by sedimentation
It is separated by solid-liquid separation.
The high moisture content of sludge is limited to its further disposition, so the top priority of sludge treatment is to be done
Change dehydration.A kind of typical sludge drying mode be carried out using external heat source and sludge heat exchange make the moisture in sludge evaporate and
Carry out the drying of sludge.But since the viscosity of sludge greatly, is mostly accumulated with clustered pattern, heat exchange is caused to be only limitted to contact with heat source
Surface, keep its drying efficiency lower.
For this reason, it is necessary to a kind of new mud drying device and method be proposed, to solve the problems of the prior art.

Wherein, the sludge is vibrated in the drying process.
In the following, being illustrated referring to Fig. 2 to a kind of sludge drying method of the invention.
Firstly, executing step S201 referring to Fig. 2: obtaining sludge to be dried.
The sludge formed after sewage treatment transports garbage burning factory by sludge conveyer, to be burnt after to be dried
It burns.During dewatered sludge, firstly, obtaining sludge from sludge conveyer.Illustratively, sludge conveyer will be dirty
Mud is delivered to the feed inlet of the mud drying device as described in embodiment one.Sludge is entered in mud drying device by feed inlet
Cavity.
Then, referring to Fig. 2, execute step S202: sludge exchanges heat with heat source sludge to be dried.
Illustratively, sludge is dried using the mud drying device as described in embodiment one.
Illustratively, the sludge is transmitted during sludge is dried.In the process that sludge is dried
The middle transmission sludge, constantly updates the sludge being dried, and the sludge after drying is delivered to incinerator and is burned, and accelerates
The efficiency of drying sludge simplifies drying steps.
Illustratively, the heat source includes hot-air, and sludge is dried using the method that hot-air exchanges heat with sludge,
Transport the direction of hot-air diffusion with sludge contrary, hot-air is blown over above sludge, effectively improves sludge
Dry rate improves drying sludge effect；The flowing of hot-air can also take away the moisture being evaporated in sludge simultaneously,
Reduce the intracorporal steam partial pressure of chamber, so that the moisture in sludge be made to be easier to be evaporated from sludge.
It is to be appreciated that the present embodiment is only exemplary the method that sludge is dried using hot-air, appoint
What connection, and drying method is suitable for of the invention as heated using heating plate to sludge
With continued reference to Fig. 2, drying method for sludge according to the present invention, in executing step S202, in the drying process
In the sludge is vibrated.Vibration is imposed to it simultaneously during sludge is dried, and turns over sludge in vibration
Different surfaces are contacted with heat source during turning, the heat exchange between reinforcement sludge and heat source.To improve drying efficiency, reduce
The time of desiccation, reduce energy consumption.Meanwhile in the example using hot-air as heat source, sludge be only capable of on transmission device with
Particular surface is contacted with hot air flow, is tended to occur form the desiccation hard shell wrapped up after the dry hardening in sludge outer surface, be made
Obtaining can not be with hot air inside sludge.After increasing vibration device, with the progress of vibration, the sludge crushing of desiccation is simultaneously sudden and violent
The part for exposing internal non-desiccation, further increases the area that hot-air is contacted with sludge, improves drying efficiency.
Illustratively, intermittent vibration is carried out to the sludge in the drying process.According between the characteristic of sludge
That has a rest imposes intermittent vibration to sludge, carrys out the speed that conditioning of mud travels forward by adjusting the frequency of motor oscillating, most
The adjusting to the moisture content in discharge port sludge is realized eventually.
In conclusion mud drying device according to the present invention and method, are using heat source to exchange heat with sludge with right
During sludge is dried, vibration processing is carried out to sludge using vibration device, turns over sludge vibration while dry
Turn, generate the different surfaces to exchange heat with heat source, to enhance the heat exchange between heat source and sludge, improves desiccation effect
Rate reduces drying time, reduces energy consumption.
