Description
Technical field
The utility model belongs to field of solid waste disposal, and in particular to a kind of sludge desiccation processing equipment.
Background technology
With Chinese society economy and the development of urbanization, the generation of municipal sewage and quantity are constantly increasing.According to having
Prediction is closed, China's municipal sewage amount can also increase by a fairly big margin for 20 years in future.At present, China produces the nearly 3 × 106t of dewatered sludge per year, with
The development of domestic sewage disposal cause, the total process water yield of sewage treatment plant and the continuous of degree for the treatment of expand and improve, institute
The sludge quantity of generation also will increasingly increase.A large amount of sludge fails to obtain timely, rational processing and sink as sewage treatment plant
The burden of weight.Also containing a large amount of N, P, K, Ca and organic matter in sludge, and N, P can have based on organic with slow release
There is long-term effect.Sludge is useful living resources, as can rationally utilizing can not only then turn waste into wealth, moreover it is possible to increase economic benefit,
So disposition is effectively treated and is had important practical significance using the technology of sludge.
Treatment of Sludge method is filled for desiccation and then again at this stage, but with the development of modern city, is gone special
It is unrealistic to be filled to take out a piece of vacant lot, in addition directly fills the recycling that can not also realize to resource.Also
A kind of method is exactly to carry out desiccation, pyrolysis, gasification to sludge, realizes the recycling of resource.Drying sludge technology is a kind of
Common can effectively reduce moisture percentage in sewage sludge in order to which it continues the technology of subsequent processing, and specific is specially to design
Sludge is heated in equipment, the process of evaporation wherein moisture can be not only effectively realized for " free in sludge
The removal effect of water ", while also " Interstitial Water " therein, " surface-bonded water " or even " internal junction Heshui " can all be played quickly
Evaporate purpose；Since the technology can be according to the requirement of subsequent processing process, by sludge drying to specified moisture content, therefore its quilt
It is widely used in existing sludge drying processing.
Drying sludge usually using dedicated sludge drier, with steam, high-temperature flue gas or just like heat conduction oil or even
Solar energy using direct or indirect mode of heating, is aided with mixing and stirring, and then reach its drying purpose as heat source.Its
In, direct heat transfer formula sludge drier, this is applying artificial Suzhou Zili Chemical Equipment Co., Ltd. on June 22nd, 2010
The utility model patent of application《Sludge drying process and equipment》It waits and is described in texts, most of them are with boiler high temperature cigarette
Gas etc. is used as heat source, is in direct contact after making it into drying machine with wet mud, by thermal convection directly to take wet mud out of
Interior moisture；This kind of mode dehumidification efficiency is high, but being in direct contact and being precipitated due to a large amount of flue gases and wet mud, and flying dust is caused to give up
Hanker that dust content is huge, and because without appropriate follow-up dust separation measure, being prone to generate the security risks such as dust explosion.
In indirect heat transmission type sludge drier, sludge and heat source are not directly contacted with, but heat transfer is carried out by way of heat transfer,
Such as apply for utility model patent filed in artificial 19 days April in 2012 of Zhejiang University《Sludge anhydration burning integrated processing system
And its technique》A kind of indirect heat transmission type drying sludge mode is just given, since sludge and heat source are separated by artificial,
It is good to heat flue gas cleannes, without related dust hidden danger, therefore using more；However, due to current indirect heat transmission type drying machine
Or in a manner that the static training of similar pot and stove is dried, cause to generate sludge settling inside it under the effect of gravity and single side occur and add
Thermal phenomenon, heating is not uniform enough, can not uniformly be parched so as to cause pending mud, and dehumidification efficiency is poor, even if as aforementioned special
Fixed and moving tooth in sharp text is staggeredly and moving teeth is in a manner of hollow Flue duct design, and mode also not only causes its complicated numerous
Superfluous, it is extremely inconvenient to safeguard, at the same its interior sludge can also be caused largely to deposit in fixed tooth lower chamber and occur not drying with
The phenomenon that direct sintering sets further, since its moving teeth flank of tooth is its vertical rotor shaft direction, how to ensure sludge after the drying
Discharge purpose, and being clearly for its mechanism can not conclusive realization；In addition, current sludge drier, since its sludge holds
Chamber of receiving needs frequently to contact dry or wet sludge always, and the accommodating chamber wear rate after severe friction is high, service life
Often influence the efficiency of actual of complete machine.How a kind of rational in infrastructure sludge drier is developed, so as to make it really
Real plays convenient and efficient drying sludge purpose, to be compeled technical barrier to be solved nearly ten years both at home and abroad.
Chinese patent publication No. CN103693829A discloses a kind of sludge treatment device and technique, and equipment includes sludge
Conveyer, sludge crushing molding machine and sludge drying machine, be provided with from top to bottom in the sludge hopper of sludge crushing molding machine by
The broken mud roller of a pair and a pair of of mud compression moulding roller of variable-frequency motor driving；The desiccation storehouse inner cavity of sludge drying machine is divided into desiccation
Room is heated in room with circulated air, if being provided with dried layer stainless (steel) wire belt transfer station, the sludge of sludge crushing molding machine in desiccation room
The discharge port of hopper is located at the surface at the transmission beginning of the stainless (steel) wire belt transfer station of top in desiccation storehouse.At the sludge
Equipment and technique are managed during being handled for municipal sludge, has that processivity is strong, period short efficient, place
Manage the remarkable advantages such as good effect, non-secondary pollution, environmental protection, stable equipment operation safety, low energy consumption, the degree of automation height.
However, the equipment is during processing sludge compacting mud item, since water content and the big sludge of stickiness are easily bonded,
Therefore the present apparatus is made to be only capable of processing water content is small and the little sludge of stickiness, use scope is significantly smaller；On the other hand, due to sludge
Stickiness be insufficient to allow its keep strip, be easily broken off accumulating in switching process so that the drying efficiency of the device is lower, no
Conducive to energy saving, which keeps the molding effect of sludge item grain using using by the way of additive, and increase desiccation into
This, is also unfavorable for green processing.
