Description
Technical field
The utility model relates to sludge treatment field, specifically a kind of air heat circulation formula mud drying device.
Background technique
Sludge drying the effects of referring to through diafiltration or evaporation, removes the process of most of water content, generally from sludge
Refer to using spontaneous evaporations facilities such as sludge drying bed (beds).High-viscosity sludge drying equipment generally uses hot wind blade drying machine, root
Twin shaft blade drying machine (vertical, horizontal), three axis blade drying machines (horizontal) can be used according to sewage sludge viscosity difference, can incite somebody to action just aqueous
85% high moisture material first drying below to eventually aqueous 12% hereinafter, drying time it is short, generally 2-10 minutes.Due to high-speed stirring
Blade high degree of agitation moist material is mixed, wet stock can well be contacted with hot wind.Material first half moisture evaporation in machine is very fast,
Hot blast temperature sharply declines in machine, therefore, even if the temperature rise of material is not also high using high-temperature hot-air.
Existing equipment takes up a large area, structure is complicated, desiccation is ineffective, and hot-air source is provided using fuel, and
It cannot recycle, waste a large amount of thermal energy, it is not very practical, it is unable to satisfy the needs of current sludge drying.

The problem of being proposed in art.
To achieve the above object, the utility model provides the following technical solutions:
A kind of air heat circulation formula mud drying device, including belt dryer, siccative storehouse and cooling tower, the belt type dry
Circulating fan is connected with by air circulating umbilical in the middle part of dry device upper and lower ends, is equipped with evaporation on the upside of the air circulating umbilical right end
Device, air circulating umbilical right end downside are equipped with condenser, and the evaporator and condenser one end branch are interconnected and have expansion valve, steam
Hair device and condenser other end branch are interconnected and have compressor, and water condenser is connected between two branches, described cold
But tower is connected with cooling pump by cooling tube.
As a further solution of the present invention: the water condenser is wound on the outside of cooling tube.
As a further solution of the present invention: being equipped with sludge inlet on the left of the belt dryer upper end.
Multiple groups conveyer belt is equipped with inside the belt dryer as a further solution of the present invention,.
Compared with prior art, the utility model has the beneficial effects that
A kind of air heat circulation formula mud drying device, structurally reasonable, novel in design, entire drying process uses
The mode of sludge at low temperature desiccation is realized without any waste heat discharge, while using the principle of dehumidifying heat pump and convection current heated-air drying
The rapid draing to sludge, greatly increase drying efficiency and desiccation effect, it is practical, meet sludge high-volume desiccation
Needs, it is practical.
