(A) full-bridge rectifier eddy current heating oil extraction technology and process. The device belongs to a fluidized bed heating oil extraction distillation equipment, by feeding systems, fluid bed eddy current heating system, oil steam distillation recovery system, slag system. 1. Feeding system The system will sieved oil diatomite to the fluidized bed by vacuum suction pump. 2. fluidized eddy current heating system The system uses advanced energy-saving technology eddy current heating, electrical energy into heat energy to provide heat to the fluid bed systems. To make oily diatomaceous earth (clay) is heated evenly, flow balance, there are fabric device installed on a fluidized bed, the share of raw materials, mixing, transport, slag, by computer-controlled mixing speed, steering, speed, so diatomite suspension in the fluidized bed, heating oil and gas spill fully vaporized, improve waste diatomite oil yield. 3. Initial boiling oil vapor recovery system vaporized oil molecules into the condenser vacuum distillation column filtration condensed to form a liquid, and then storing it into the finished product tank. Condensate system uses water condensation and freezer condensing two ways. The system uses a vacuum pump and a vacuum buffer tank to a negative pressure throughout the system, to ensure that the whole system is stable and reliable and safe operation. 4. Oily waste slag system diatomaceous earth (clay) after passing through the fluidized bed heat treatment, the formation of sludge in line with national emission standards diatomite into sieve storage tank, the storage tank of slagging mouth open timing, timing Emissions for recycling .5 rolling oil distillation system regeneration system proposed by IBP rolling oil distillation system after removing the aluminum scrap, impurities, oil and hydraulic oil, then aluminum foil rolling mill generates reached using oil. (B) Major equipment 1. Vacuum diatomite oil feeding pump; 2 eddy current heating fluidized bed; 3 primary tower; 4. 5. vacuum distillation column, vacuum tank; 6. 7. condenser discharge 8. 9. slag recycling pool of computer electrical control cabinet. The device has an automatic alarm device, such as a system exception occurs, the alarm system will automatically turn on, the whole system will automatically stop working. By the above oil diatomite processing equipment, rolling oil and diatomaceous earth to separate physical method, the molecular structure of diatomite and rolling oil will not cause damage, and to ensure that the Diatomite original rolling oil performance, rolling oil can be used continuously in the aluminum industry, will not affect the products and equipment; diatomaceous earth because it contains aluminum powder particles can be used as building materials industry, raw materials for reuse. C) The economic analysis of the full-bridge rectifier eddy current heating oil extraction diatomite rolling oil equipment, design production processing diatomite two tons a day, (eight hours of work) to extract the rolling oil 600kg. Oil by 10,000 yuan per ton rolling basis, the daily income of 6,000 yuan, 180,000 yuan monthly income, total power 88kw, two artificial class, labor costs 200 yuan, 704 yuan of electricity, (1 yuan per kilowatt basis) in raw material costs calculation by 900 yuan per ton, the total cost of 2704 yuan, the total cost of 81,120 yuan, 98,880 yuan monthly profit (diatomite processing is not included in the profits later). Daily output can be requested on demand design. D) Environmental analysis of the process of oil extraction genus physical Celite, the whole process does not use pH or other harmful substances, and under vacuum conditions, there is no emission, diatomaceous earth after the oil content not greater than the processing 3000mg / kg, in line with the national standard GB4284-84, new technology is environmentally friendly.
