Description
Technical field：
The present invention relates to sludge medium temperature belt-type drying field, in particular to a kind of sludge medium temperature belt drying system.
Background technology：
Because fuel cost and freight constantly rise violently, sludge treatment becomes more difficult and expensive at present.In order to anti-
The only diffusion of methane and carbon dioxide, while should not also allow pollution burden to be transferred to offspring from the point of view of long-term plan, Europe at present
Man of ally no longer allows dewatered sludge directly to fill.For the U.S. and China, it is straight also will progressively to abandon sludge from now on
Connect the disposal options of landfill.
Sludge can be incinerated, and remaining ashes are all inorganic substances, can carry out landfill stabilization.It is but now many
Nutriment can be lost.Know from the analysis of global phosphor resource storage capacity, can be limited as the phosphor resource of fertilizer.Because ashes
In contain each heavy metal species, therefore these ashes rich in phosphorus content generally can not use directly as agricultural fertilizer.Although at present from
The method of recovery extracting phosphorus is many in ashes, but caused phosphorus price is sufficiently expensive, also without commercial value.Sludge incineration produces
These ashes at present can only temporarily in special landfill yard, wait from now on phosphorus price rise after carry out exploitation recovery again.
Although dewatered sludge can be burned directly, since it is desired that evaporation moisture content can consume big calorimetric in this burning process
Energy.In addition dewatered sludge is frequently necessary to long distance transportation to burning (such as large-scale coal-fired plant), now also must additionally consume
Expensive fuel.
The mud originally generally used is to carry out sludge recycling, i.e., directly as agricultural fertilizer.In some Europe
Continent country, such as Holland and Northern European countries, set permission pollutant load is so low, and in fact these municipal sludges have been
Can not possibly be agricultural.In the case that agricultural sludge allows, because sludge transportation range and expense are also being continuously increased, this
Treatment approach will become more and more difficult from now on.In the U.S., situation is somewhat different, as long as sludge disinfection can reach grade A, change can
To be used as agricultural fertilizer.
No matter sludge is recycled or be incinerated disposal, the water content in usual dewatered sludge is in 75-
85% scope, if becoming have no economic implications if long-distance transportation these moisture content.If dewatered sludge can be done in advance
Change is handled, such as from 25%DS desiccation to 90%DS, sludge weight will decrease to original 28%.The calorific value of dewatered sludge compared with
Height, similar lignite, carbon dioxide can be used as generative fuel to carry out cogeneration of heat and power in neutrality.
Under this background, the quantity cumulative year after year of European sludge desiccation processing equipment.In the last few years, in the U.S. with
State also begins to build sludge desiccation processing equipment.Freight can be not only reduced after sludge drying, and these desiccation are dirty
Mud also becomes easily simple when coal-fired plant or cement kiln carry out incineration disposal.
Existing sludge desiccation processing equipment mainly includes wet feed storehouse, screw pump, sludge extruder, desiccation main frame, ring wind
Blower fan, chemical deodorizing tower, biofilter etc.；Wherein formula drying system in temperate zone is a kind of equipment of desiccation main frame, and he is extrusion
Machine extrusion strip sludge carries out follow-up desiccation；But warm belt dryer is only accumulated strip sludge on the belt, leads to
The hot gas crossed from top to bottom carries out desiccation；The contact area of so sludge and hot-air is limited, the final effect for influenceing desiccation.
The shortcomings that existing for such scheme, it is necessary to provide a kind of new scheme to solve this problem.
