Described hot-air system comprises hot blast chamber 16, hot air duct 18, blower fan 17, heat exchanger 19 and hot well tank 18, and described hot blast chamber 16 is arranged at the bottom of this mummification canopy, is positioned at below the drying bed of the lowest layer.Described hot blast chamber 16 is connected with heat exchanger 19 by hot air duct 18, by heat supply water pipe 20, with cold water return pipe 21, with hot well tank 23, is connected, and described heat supply water pipe is provided with water pump 22, on described hot air duct 18, is provided with blower fan 17.Be provided with scraper 15 in hot blast chamber 16, by scraper 15, scrape the small-particle mud of landing at hot blast chamber 16, prevent from stopping up the hot blast circulation.This scraper 15 can be described as again cleaning shoe, is similar to a flat board of traction, can be used for mud on ground is blown off.The thermal source of heat exchanger 19 preferably comes from the waste heat that & Mud produces.The thermal source of described hot well tank comes from waste heat that used heat that Biogas Generator Set produces or the waste heat in waste heat and/or second pond draining, waste heat flue gas and/or thermal hydrolysis technology produce or used heat etc.
This mummification canopy also is provided with microcomputer monitoring and Controlling System, every layer of described mummification chamber 4 all is provided with Temperature Humidity Sensor 24 and/or camera (not shown), and described microcomputer monitoring and Controlling System are electrically connected to by wire and roll-over 6 in paver 13 and/or cloth material spreader 9 and/or mud and/or Temperature Humidity Sensor 24 and/or camera and/or skylight 2 and/or side window 3 and/or blower fan 17.Microcomputer monitoring and Controlling System are used for controlling operation or the stationary state of paver 13 and cloth material spreader 9 and controlling the unlatching of mud roll-over 6 bottom valves 7 or close.Temperature Humidity Sensor 24 is for detection of the temperature and humidity of mummification chamber interior, and the temperature and humidity signal detected is sent to microcomputer monitoring and Controlling System.Camera is used for monitoring the situation of mummification chamber interior, and sends the monitored picture photographed to microcomputer monitoring and Controlling System.Can also control the unlatching of Temperature Humidity Sensor 24, camera skylight 2, side window 3, blower fan 17 equipment or close by microcomputer monitoring and Controlling System.Can reduce human input by microcomputer monitoring and Controlling System, the accuracy-control system parameter, improve mummification efficiency, guarantees the orderly operation of security of system.
The mummification chamber 4 that is arranged in top layer is provided with mud roll-over 6, and in described mud, the bottom of roll-over 6 is provided with valve 7.In mud, roll-over 6 is for receiving the mud transported from spiral conveyer 5, when mud is collected certain degree, cloth material spreader 9 stop at roll-over 6 in mud below, in mud, the valve 7 of the bottom of roll-over 6 is opened and mud is moved in cloth material spreader cloth bucket 8.In mud, the effect of temporary transient storage mud is played in roll-over 6, thereby the cloth time that can balance and stability cloth material spreader by roll-over 6 in this mud guarantees normally to produce in order.
During the operation of the hot air combined sun power sludge drying of the utility model multilayer greenhouse type canopy, mud is transported to mummification canopy main body 1 by spiral conveyer 5 and is arranged in the 4 mud roll-overs 6 of top layer mummification chamber.When sludge accumulation, after applicable quantity, in mud, roll-over 6 storehouse bottom valves 7 are opened, and mud falls in cloth material spreader cloth bucket 8.In cloth material spreader cloth bucket 8, mud is shed on sludge drying bed 12 by cloth material spreader 9.Cloth material spreader 9 is on the walking track 10 of sludge drying bed 12 during walking movement, throw the effect of cutter by the cloth material spreader with certain angle of inclination, mud is diminished by bulk, and the longitudinal displacement with cloth turnover throwing machine traffic direction had both occurred in mud, the transversal displacement that also is parallel to cloth material spreader itself, the slowly side to right opposite discharge port 11 places by the sidesway at cloth material spreader cloth bucket 8 places.
Mud falls to one deck mummification chamber from top layer mummification chamber discharge port 11, then the paver 13 in this mummification chamber is paved mud, throw the effect of cutter by the paver with certain angle of inclination, sludge bulking further diminishes, and the longitudinal displacement with the turnover throwing machine traffic direction had both occurred, the transversal displacement that also is parallel to paver itself, slowly shift to discharge port 11 positions.
Until, after mud falls to the most the lower layer of mummification chamber, paver 13 is paved mud, mud granule further diminishes, the displacement of mud granule generation vertical and horizontal.The mud that transversal displacement occurs moves on on the belt conveyor 14 of mummification chamber one side gradually, is transferred out outside the mummification canopy.Fig. 2 is mud traffic direction schematic diagram under the utility model cloth material spreader 9 or paver 13 effects, mud longitudinal displacement direction is identical with cloth material spreader or paver direction of travel, mud transversal displacement direction is parallel with the fuselage direction of cloth material spreader or turnover throwing machine, the angle of mud actual motion direction and transversal displacement direction is by the angle of inclination decision of throwing cutter, and the transversal displacement speed of mud is determined by the length of throwing cutter.In mud drying process, on the one hand, the sun power direct radiation is to Sludge Surface, and heating mud, make its internal moisture be able to air towards periphery and accelerate evaporation, thereby increased the atmospheric moisture of Sludge Surface, reaches capacity even.On the other hand, the hot blast come by heat exchanger 19 heat exchange enters in hot air chamber 16 by blower fan 17 effects, hot blast in hot air chamber 16 passes through drying bed, with Sludge Surface, strengthening contacts, heat is inputted to mud, take away the wet air of Sludge Surface, improved the water-retaining capacity of Sludge Surface air, thereby, impel further air evaporation towards periphery of mud internal moisture.Mummification canopy main body 1 is made by sunlight board except supporting structure, can keep the mummification temperature of shed between 30～50 ℃, guarantees the speed of sludge water content evaporation.In addition, when the water ratio in mud reduces to nearly 40%～60%, in mud, organism can be fermented under the condition of aerobic, thereby causes the further rising of mud internal temperature, plays the mummification effect of accelerating, and also makes mud obtain stabilization treatment simultaneously.
When Temperature Humidity Sensor 24 detects the mummification indoor humidity and reaches a threshold value, open side window 3 and skylight 2 by microcomputer, get rid of in time wet air.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
