Arrange one in mummification room 1 and turn over mud machine 5, if mummification room 1 is excessive, also mummification room 1 can be divided into multiple mummification locellus, arrange respectively in each mummification locellus and turn over mud machine 5, multiplely turn over compared with mud machine 5 with arranging in a space, not only turn over situation about colliding between mud machine 5 can avoid, control also to be more prone to.
Below the principle of work of the sun power mud drying device of present embodiment is described.
Mud mainly has following three kinds of drying process in greenhouse: 1. radiation mummification, after the mud of bottom, mummification room 1 (greenhouse) accepts outside solar ray Net long wave radiation through transparent mulch film, temperature raises, its internal moisture is able to air towards periphery and accelerates evaporation, because mummification room 1 is semi-closed structure, thus the atmospheric moisture of Sludge Surface is increased, reach capacity even; 2. when interior sensor 8b detects that atmospheric moisture reaches capacity, mummification controller 6 opens air circulation fan 4 and air hole 2, by natural circulation or ventilation, wet air in greenhouse is discharged, the humidity of Sludge Surface is made to enter unsaturated state by original state of saturation, thus impelling mud internal moisture air evaporation towards periphery further, the latter occupies prior position in mud drying process; 3. when the water ratio in mud reduces to nearly 40% ~ 60%, in mud, organism can ferment under the condition of aerobic, at this moment the further rising of the internal temperature of sludge can be observed, mummification controller 6, mud machine 5 is turned in the startup reaching certain value or timing at mud internal temperature, stirs mud, makes the fermentation of mud remain on most suitable state, accelerate mummification effect, also make mud obtain stabilization treatment simultaneously.If natural circulation or ventilation cannot reduce the humidity of Sludge Surface, mummification controller 6 starts the blower fan in vent window 3, carries out pressure air draft, and this especially can meet the needs of big area greenhouse lignin-sludge.4. in drying process, turn over mud machine 5 and turn over mud automatically, make mud obtain regular stirring and mix homogeneous, thus the evaporation area that constantly updates, also play oxygen supply effect simultaneously, avoid sludge inside occur local anaerobic and discharge foul gas.
The following whole process that sludge drying is described according to Fig. 2.
The treatment stage that the mud drying process of one-period being divided into following:
(1) mud section is entered
Enter mud (mud as 80% water ratio) when one-period starts, available sludge pump is directly input into mummification room 1 (drying bed) mud from opening for feed, also can be transported into mummification room 1 by truck.Filtrate in mud has water exhaust system to discharge.
(2) dryer section
Start trip switch, mummification controller 6 is according to the detected value of sensor 8a and interior sensor 8b, automatic control air hole 2, vent window 3 and turn over mud machine 5, make the moisture of mud evaporate under the irradiation of sunlight and make the organism in mud at the condition bottom fermentation of aerobic.The whole process of mummification is carried out automatically, when mud solid content reaches requirement, controls drying process and terminates, transported by truck.
In operational process, the following parameter of mummification controller 6 continuous print monitor and forecast, automatically regulates, guarantees mummification effect:
(1) temperature of air;
(2) relative humidity of air;
(3) mud temperature;
(4) mummification indoor air flows speed;
(5) surface tissue of mud and humidity;
(6) environmental conditions (temperature, relative humidity, solar radiation
(3) spoil disposal section
Because organic content reduces greatly after mummification, usual volume can reduce 3 ~ 5 times, and water ratio reduces 80%, therefore after mummification, the indoor mud height of mummification only has several centimetres usually, whole process can pass through Microprocessor S3C44B0X, and realize complete mechanical, hand labor intensity is little.Due in drying process, control the evaporation of moisture and stir mud, mud is prevented to ferment in the absence of oxygen, produce the smell pollution environment such as foul smell, under making the mud most cases after mummification, smell can be identical with the smell of earth, mud after final mummification discharges mummification room by forklift, and the car that is installed transports.
In the present embodiment, turn over mud machine 5 also referred to as " electronics mole " in order to improve the homogeneity of mummification speed and product and stop sludge blanket to produce anaerobic zone and produce foul smell, a set of can trust high efficiencyly to dig, to stir and oxygenate apparatus is very important.
" electronics mole " that present embodiment is used, it is a kind of four-wheel robot controlled by micro-chip processor, digs, stirs and carry out oxygenation to mud.Electronics mole is made up of height rot-resistant material stainless steel and acrylic, ensure that longer work-ing life and minimum maintenance capacity.
Electronics mole can be located by built-in sonac automatically in mummification indoor, density of digging can according to the character of mud in wider scope by change dig rake quantity, shape and stir speed to adjust, can take the air line, also cellular curve can be walked, therefore electronics mole is very flexible and ingenious device, controls easily.The concrete structure of electronics mole (turning over mud machine 5) is in following detailed description.
Because electronics mole (turning over mud machine 5) is arranged in mummification room 1 (solar energy desiccation room), by the reciprocal walking of electronics mole, the mud of such as water ratio less than 95% is stirred, prevents mud in drying process from hardening, the moisture in mud is fully evaporated.Be under the condition of heat energy in sunlight transform light energy, Full-automatic circulation ventilation system in glass sunlight house, such as by conversion fan operation angle, air in glass sunlight house is made to form turbulent flow, the sludge water content evaporation that it opens electronics mole, does not increase other thermals source and the sludge drying of water ratio more than 95% just can be made to be the siccative of water ratio less than 40%.
As from the foregoing, the sun power mud drying device of present embodiment has following features:
1, utilize natural sun power as main energy sources, power consumption and operational and administrative expenses low;
2, after process, sludge volume can reduce 3 ~ 5 times;
3, system run all right safety, temperature is low, and dust generation is little;
4, simple, the long service life of Operation and Maintenance;
5, complete mechanical, automatization;
6, system transparent degree is high, and environment compatibility is good, does not produce peculiar smell;
7, the needs that mud stores can be solved simultaneously.
Compared with prior art, owing to not needing large-scale training equipment, simple to operate, day-to-day operation and maintenance cost are very low, eliminate the generation of the peculiar smell such as foul smell, can not to environment.
Dried mud can make the particle shape of odorless, so both as Fertilizer application, can burn again as biofuel.Therefore the sun power mud drying device of present embodiment is highly suitable for solar energy resources and enriches, and the area of other energy deficiencies uses.
The mud of process can be any kind, does not dewater, half dehydration or entirely dewater, aerobic without the mud after oxidation stability or raw sludge, domestic sludge or industrial sludge, simultaneously flexible to entering the requirement of mud solid content.
For verifying effect of the present invention, contriver uses it for actual project and tests, and its condition is as follows:
Sludge quality: the municipal sludge after belt filter press;
Enter mud solid content: 20%;
User is to the requirement of mud extraction: the mud solid content after dehydration: >=60%;
Day enters mud amount: 30m
3/ d;
The condition determination drying bed area such as weather condition, solar radiation situation, drying bed geographical position according to scene is 5400m
2.
By checking, demonstrate sun power mud drying device of the present invention, can not only save energy, simple to operate, day-to-day operation and maintenance cost are very low, can also prevent the peculiar smell such as foul smell from occurring, can not to environment.
