USE - Solar cryogenic distillation of domestic garbage.    ADVANTAGE - The method is carried out using clean solar energy, achieves household garbage reduction, is energy efficient, has low operating costs, and environment friendly.    DETAILED DESCRIPTION - Solar cryogenic distillation of domestic garbage comprises processing garbage in cryogenic distillation plant comprising operating system (001), energy transfer system (002), and monitoring system (003); transporting domestic garbage into cleaning workshop (31); screening and classifying domestic waste for next production process; and separating and purifying. The operating system can be divided into dry distillation system, preprocessing workshop, cleaning workshop, sorting workshop (43), drying room (44) and workshop. The dry distillation system is used for drying coal at low temperature via solar energy from sun. The energy system comprises lighting system, energy output system, and conveying system. The monitoring system comprises cooling medium cantilever type solar energy tower (32), hydraulic pump station, master control room, cooling medium type solar panel, water storage, transmission and power distribution room, power supply automatic switching switch, and national power grid. The cleaning workshop comprises conveyer A, small mesh basket ring, conveying hopper A, disc ring, water outlet, steel cable small mesh basket, inclined nozzle, disc, cleaning and classifying tank, hot water storage tank, hot water pipe and valve, cold water pipe and valve, grab bucket, pressing plate bracket, steel cable large mesh basket, mesh basket ring, hoist crane, opening and closing ring, conveying hopper B, water overflow port, water collecting groove, conveyor B, concrete floor, and water discharging pipe and valve. It uses half-wall type pavilion structure to facilitate work environment ventilation. The cleaning grading pool uses same high-grade concrete casing. It has sidewall that is higher than floor wall and provided with water overflow port, oil water interface, and concrete floor provided with water collecting groove in corresponding relation to oil-water collecting groove. The cleaning and grading tank is close to diameter of tank wall. The hot water pipe is provided with valve that is connected to inclined nozzle at angle of 60 degrees and inclined angle of 45 degrees to provide cleaning, grading and rolling flow. The cleaning and classifying tank is provided with water discharging pipe and valve that is connected with water outlet. The water outlet and inclined nozzle are set with inclined orifice. The cleaning and classifying tank is connected with level, which is convenient for grab bucket-turning during cleaning operation. The pressing plate has disk-shaped, reinforced concrete structure and includes holes with size slightly smaller than cleaning and classifying tank. The pressing plate is provided with at least three pressing disk hanging rings and pressing plate. The crane includes hoist and ballast for decompressing fractionation product cleaning operation. The pressing plate and station are provided in cleaning and classifying tank. The pressing plate is placed on disc bracket, on top surface of water overflow port to allow overflowing of oil-water mixed liquid. The cleaning and classifying tank is designed as single tank capable of batch processing 10 tons for 100 minutes, and daily treatment capacity of 200 ton/day. It includes large steel cable mesh basket similar in size with cleaning and classifying tank. The steel cable large mesh basket is placed in cleaning and classifying object arranged on cleaning and classifying pool located on small steel cable mesh basket. The steel cable large mesh basket and small steel cable mesh basket have periphery provided with at least four large mesh basket rings and small mesh basket ring. They are also provided with cleaning and grading release device at angle of 90 degrees . The release device has bottom divided into four adjacent edges and provided with opening and closing ring with bolt formed by injection molding. The conveying hoppers A and B are located in cleaning room of two adjacent cleaning and classifying tanks in middle of column. The water outlet of cleaning and classifying tank is connected with water pipe and valve to sewage pump or directly to discharged wastewater depositing and purifying pool. The cleaning and classifying tank is separated into upper and lower parts. It is used for cleaning household garbage in hot water under rolling, rotational flow and gravity method based on physical principle of domestic garbage automatic classification to obtain three different chemical components having specific gravity smaller than liquid mass of water, specific gravity smaller than organic solid material to water, and specific gravity larger than inorganic solid matter.
