Effect operation, the hot wind after dedusting reach heat-exchange system 12, and the air that heat-exchange system comes out enters back into heat pump system 14, at this time
The condensed water condensed out passes through 13 outlet of condensate draining pipe, and outlet air reenters dry chamber via breeze fan 15 again
In body 1, recycle.
A kind of sludge reduction low-temperature drier proposed by the present invention, its advantage is that: for common low temperature desiccation first layer
The susceptible to plugging problem of conveyer belt, the present invention turn over polishing apparatus in the setting of first layer conveyer belt, and sludge is prevented to be deposited in transmission for a long time
It takes, blocking risk is reduced with this.Common low temperature desiccation machine is mostly bottom air distribution combination circulating fan return air, and there are hot winds and dirt
Mud time of contact short problem, and the problem of top hot wind humidity is larger, and moisture absorption efficiency declines, overall efficiency of heating- utilization is only 50
~60%, invention on the basis of the air distribution combination circulating fan of bottom, moisture percentage in sewage sludge highest and air moisture absorption efficiency it is minimum
First layer conveyer belt on be provided with side air-distribution device, by control side air-distribution device wind speed, guarantee and air supply at the bottom
Cutout is not formed, it is by controlling the wind direction of side air-distribution device, i.e., contrary with conveyer belt operation, it is inversely connect with sludge
Touching, extends contact time, and thus improves the desiccation effect of first floor sludge, makes full use of to hot wind heat.In addition, common low temperature is dry
The dust heat pump system easy to damage that change machine generates, even if being provided with dust-extraction unit, dust clears up dedusting after being trapped by dust-extraction unit
Device filter bag be very much it is cumbersome, reduce equipment ease of use, the present invention from the filter bag selection of dust-extraction unit first select prevent it is quiet
Electric fiber polymer nano material, efficiency of dust collection is up to 99.5% or more, while the material of antistatic greatly avoids powder
Dirt hidden peril of explosion that may be present, to be also provided with back-blowing device after avoiding manual cleaning dedusting filtering bag, what back-blowing device was blown down
Ash can be handled by bottom ash bucket collection.The improvement of equipment improves on the whole reduces conveyer belt blocking risk, optimizes cloth wind
Mode improves the manner of cleaning up of dust-extraction unit, improves the ease of use of equipment, keeps the equipment efficiency of heating- utilization higher,
It can reach 70% or more, thus can reduce operating cost, it is more energy-efficient.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
