Description
Technical field
The invention belongs to the technical fields of sludge heat drying, solid waste thermal desorption and thermal decomposition, and in particular to a kind of circular pipe type
Desiccation machine.
Background technology
In fields such as the energy, chemical industry, oil, textile printing and dyeing, papermaking, municipal administrations, it will usually it is higher to generate a large amount of water capacities
Sludge.
The ingredient of sludge is extremely complex, in addition to containing a large amount of moisture, also contains a large amount of organic matter, difficult to degrade organic
The ingredients such as object, various trace elements, pathogenic microorganism and parasitic ovum, heavy metal, and with stench.
The method of disposal of sludge has landfill, agricultural, burning etc. at present.Sludge incineration has minimizing, innoxious, recycling
Remarkable advantage.All germs are killed during the burning process, and heavy metal stabilizing improves, and toxic organic compound is by oxidation point
Solution, the volume of the remaining ash of sludge is far smaller than the volume of sludge after mechanical dehydration after burning, about its 1/10th.It is alive at present
Sludge incineration, which is obtained for, within the scope of boundary is widely applied, and will be further increased in the ratio of the following sludge treatment.
For the more method for sludge treatment of foreign applications to be burned after first desiccation, the current type of anhydration system of sludge is numerous at present
More, investment production capacity and operating cost, whether generating secondary pollution etc., techniques difference is larger.In such a way that thermal medium is contacted with sludge
It can be divided into：Direct Contact Heating formula, mediate contact heated type, non-contact heated type, dual heating type etc..
Mediate contact heated type is to heat wall with thermal medium (such as steam, conduction oil, fused salt), to keep wall another
The wet mud of side is heated, moisture evaporation, belongs to conduction heat transfer mode.Mediate contact heated type dry, advantage be thermal medium not
It is in direct contact with sludge, but wet mud is contacted the heat to by heat exchange partition, make the moisture evaporation in sludge, heat carrier is not
It can be polluted by sludge, the dry tail gas amount very little generated, the dry thermal efficiency is higher, and tail gas deodorization is easily handled.
According to sludge water content how much, it is several that sludge drying generally undergoes mushy zone, stagnant zone, blocky area, granulomere
Process, then sludge obtain desiccation moisture and continuously decrease.It is using wider mediate contact heated type desiccation machine at present：Groomed oar
Leaf desiccation machine and disk desiccation machine.The sludge drying of both desiccation machines is all indirect by thermal medium from the inlet side of desiccation machine
Heat and be gradually moved into discharge end, sludge under the scraping blade and screw blade of heating surface surrounding push inside the desiccation machine can only before
Into back-mixing cannot be retreated to feed end.The sludge retention that this has resulted in both desiccation machines is long in the stagnant zone time, dirty at this time
Mud is easily adhered to not easily to fall off on heating surface, and causing sludge thermal resistance to increase desiccation rate reduces, although broken by scraper scraper plate
Broken sludge, but the viscous problem of sludge cannot be all solved very well.
In addition, with the progress that sludge drying is dehydrated, sludge volume largely reduces, the rear end heating surface of both desiccation machines
The sludge quantity that year-on-year front end heating surface touches subtracts greatly, and it can only be bottom part heating sludge, heating surface to cause rear end heating surface
Effective heat utilization is not obtained, is equivalent to and is wasted part heating surface.
In addition, the axial heating surface use of both desiccation machines master is all plank frame, this structure bearing capacity
Difference, so when as used steam desiccation, it is 0.2~0.8MPa that can only generally control highest saturation vapour pressure, this corresponding limitation
The temperature of heating steam improves, and is unfavorable for improving the desiccation rate of heat transfer of unit area.
It is removed in addition, both desiccation machine desiccation exhaust gas used at present just carry out whirlwind after connecting pipe leaves desiccation machine
Dirt, this causes desiccation exhaust gas to block connecting pipe with a large amount of dust, and the remoter distance the more serious, and collected outside dirt also results in system
It is complicated.
Invention content
In order to overcome current technology there are the shortcomings that, the object of the present invention is to provide a kind of circular pipe type desiccation machines.

The circular pipe type desiccation machine sludge drying course of work is such：
Thermal medium (conduction oil or steam, fused salt etc.) a-road-through crosses the entrance of thermal medium inlet rotary joint 17, by import
Spindle nose 15 enters the thermal medium inlet manifold 25 in hollow hot axis 13, then enters side by side each by thermal medium inlet manifold 25
Import endless tube header 20 in the pipe heating dish 14 of a heating sludge, using several circles heat exchange endless tube of pipe heating dish 14
19 (are in Fig. 4 four circles heat exchange endless tube 19) are collected into discharge ring header 21, then thermal medium enter in hollow hot axis 13 and
Annular space space between thermal medium inlet manifold 25 is flowed out using outlet spindle nose 16, thermal medium outlet rotary joint 18, and heat is situated between
Matter delivers heat to sludge drying by the outer surface of each pipe heating dish 14 and hollow hot axis 13 and uses.
Thermal medium (conduction oil or steam, fused salt etc.) another way is added by chuck thermal medium inlet 5 into jacket type simultaneously
Heat engine shell 3 provides heat by the inner surface of chuck and is used to sludge drying, and the thermal medium after heat exchange is gone out by chuck thermal medium
Mouth 6 flows out.
Wet mud is transported to sludge inlet 8, after the dispersion of sewage sludge feed dispersion machine 9, is sent into the jacket type of desiccation machine
The hot axis pipe heating dish group 4 heated in casing 3 carries out desiccation.
Transmission mechanism 1 drives hot axis pipe heating dish group 4 to rotate, and wet mud falls into the pipe heating dish of feed end first
14, it is then gradually passed through every by the more dry sludge agitation mixing in the part for stepping back the return of scraper plate 24 with sludge discharge end herein
The heating of group pipe heating dish 14 and propeller 23 move pusher to the sludge discharge hole 26 of discharge end so that dewatered sludge is arranged
Go out desiccation machine.
