Background technology
Current China sludge disposal technology is broadly divided into burning and mummification.But the investment needed for sludge incineration is large, and working cost is high, so without particular requirement, generally do not adopt the method for directly burning.Sludge drying uses the widest method at present, and through the development of decades, the advantage polluting drying technique just displays, and mainly contains mud and significantly subtracts appearance; Form particle or powdery stable prod, sludge character improves greatly; Product odorless and pathogen-free domestic; Product serves many purposes.Can, so will realize the recycling of mud, sludge drying be the important the first step, and the cost of sludge drying is mainly heat energy, therefore select appropriate thermal source to be the key point reduced costs.
The legacy equipment of sludge drying mainly contains:
1, direct-heating type, principle is convective heating, and the equipment of representative has rotary drum, fluidized-bed etc.;
2, indirect heating type, principle is conduction or Contact Heating, and the equipment of representative has spiral, disk, thin layer, video disc, paddle etc.;
3, thermal radiation heating-type, have belt, spiral etc., but these operations of equipment is complicated, need higher running cost.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of device utilizing solar energy desiccation mud, its cost of manufacture is cheap, sludge drying successful, a step mummification of mud can be realized, and in mud, moisture reclaims and the recycling of mud after mummification, has very large application and popularization value.
The utility model solves the technical scheme that its technical problem adopts:
A kind of Novel sewage sludge drying device, comprises the bracing frame be obliquely installed, and is parallel to be provided with mud pan and transparent glass baffle plate bottom it in support frame as described above, and wherein said transparent glass baffle plate is fixed on above bracing frame, and with its formation mummification greenhouse.
As the improvement of technique scheme, be provided with adjusting bracket below support frame as described above, it makes bracing frame angle of inclination can be regulated with maximum using sun power according to optimum illumination.
As the improvement of technique scheme, be provided with some auxiliary bars in described mud pan, it glides to make mud obtain farthest evenly mummification for preventing mud.
As the improvement of technique scheme, under support frame as described above, place is provided with drip tray, it is for being collected in the moisture of device evaporation and condensation in mud drying process.
As the improvement of technique scheme, in support frame as described above, be provided with vacuum fan, its for the stiffening device inner air convection when sunlight is sufficient not with accelerate sludge drying process.
As the improvement of technique scheme, support frame as described above is built-in with temperature & relative humidity indicator.
The beneficial effect that the utility model brings has:
This Novel sewage sludge drying device technique, compared with conventional art, possesses following advantage:
1, equipment making technique is simple, and operational and administrative expenses is cheap, and current consumption is only about 5% of traditional drying technique, cost-saving;
2, after process, moisture percentage in sewage sludge can be down to about 10%, and sludge volume reduces can reach 3 ~ 5 times, can realize a step sludge drying process, successful;
3, equipment configuration is little, easy to assembly, stable equipment operation safety, and dust generation is little, and Operation and Maintenance is simple, long service life;
4, system transparent degree is high, and environment compatibility is good, utilizes renewable energy solar energy to originate as main energy sources, meets the demand of Sustainable development;
5, solar energy desiccation device of sludge manufacturing process is ripe, and technical requirements is lower, is convenient to large-scale promotion use, is easy to build.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,
Accompanying drawing 1 is structure side view of the present utility model;
Accompanying drawing 2 is structural front view of the present utility model;
Accompanying drawing 3 is support frame structure schematic diagram of the present utility model.
Embodiment
With reference to accompanying drawing 1 to accompanying drawing 3, the utility model is a kind of device utilizing solar energy desiccation mud, and its cost of manufacture is cheap, sludge drying successful, can realize a step mummification of mud, and in mud, moisture reclaims and the recycling of mud after mummification, has very large application and popularization value.
Concrete, this device comprises the bracing frame 1 be obliquely installed, and is parallel to bottom it and is provided with mud pan 2 and transparent glass baffle plate 3 in bracing frame 1, and wherein, transparent glass baffle plate 3 is fixed on above bracing frame 1, with its formation mummification greenhouse.Because the radiation of transparent glass for less than 3 μm has preferably through ability, therefore sunlight ray can arrive mud pan 2, mud and air by transparent glass baffle plate 3, and changes into heat energy, forms Greenhouse effect, reaches the effect of drying mud.
Meanwhile, below bracing frame 1, be provided with adjusting bracket 4, bracing frame 1 can be made to regulate angle of inclination, with maximum using sun power according to optimum illumination.For preventing mud from gliding, in mud pan 2, being provided with some auxiliary bars 21, obtaining farthest evenly mummification to make mud.In mud drying process, the moisture of device evaporation and condensation will come together in the drip tray of bracing frame 1 time edge place's setting.In addition, in bracing frame 1, vacuum fan 5 can be set, for the stiffening device inner air convection when sunlight is sufficient not with accelerate sludge drying process.
The process of this Novel sewage sludge drying device dewatered sludge can be divided into:
1, radiation mummification, after mud in device accepts outside sunlight Net long wave radiation, temperature raises, mud internal moisture is made to move quickly into Sludge Surface by capillarity, add the moisture content of Sludge Surface, evaporate rapidly after reaching capacity, flow to drip tray after the transpiring moisture transparent glass baffle plate 3 arrived in device forms water droplet, realize the recycling of moisture.
2, convection current mummification, when sunlight is very weak, the ventilation plant that device both sides are arranged plays the leading role of sludge drying, by convection of air effect, wet air in device is discharged, make the humidity of Sludge Surface enter unsaturated state by original state of saturation, thus impel mud internal moisture air evaporation towards periphery further.
3, when the water ratio in mud is evaporated to 40% ~ 60%, the organism in mud carries out aerobic fermentation, and the temperature of release plays accelerates mummification effect, makes mud obtain stabilization treatment.
It should be noted that above-mentioned three drying process carry out simultaneously.
In order to accelerate the evaporation of moisture in mud, this device is provided with telescopic lifting adjusting bracket 4 and built-in temperature wet bulb thermometer, the angle of inclination of sun power mud drying device is regulated according to local optimum illumination, reach maximum using sun power, what make the sludge drying time become manipulates simultaneously, realize semi-automatic and full-automatic technique, make it adapt to the demand of mummification operation under different weather and Various Seasonal condition, shorten treatment cycle.
In addition, this device also can combine from different sludge disposal equipment, becomes a transfer platform towards different sludge disposal approach, reaches and reduces sludge disposal expense, improves the handiness object of disposal means.
It should be noted that, the above is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
