Abstract
Description
Bio-energy raw material extraction technology field
The present invention relates to an oil extraction and purification system for extracting oil from a desalination liquid of food waste and using it as a raw material for energy, including a method of heating during refining and a refining method
It is a resource system.
Food waste is produced and circulated as a part of feed, compost, and energy recycling products, and the final waste is disposed of by incineration and incineration. Wastewater from food waste is high concentration wastewater and contains oil, which is an obstacle to the formation of oily membranes in the process of removing organic matter by ingesting organic matter of microorganisms.
In addition, the oil in the desalination liquid inhibits the clogging of the equipment and the piping line, the function of the filtration equipment, and shortens the service life.
By separating the oil, sludge, and wastewater through a three-phase centrifuge, the sludge is recycled as feed or compost, the oil is used as a raw material for bio-energy, and the properties of wastewater are greatly improved.
The oil extracted using a three phase centrifuge is only valuable as a raw material of energy when subjected to a primary purification process.
In a facility that produces biogas, it removes the oil that adversely affects the digester
The production of biogas is increased.
FIG. 1 is a view illustrating a process of separating a three-phase centrifugal separator into sludge, oil, and wastewater in a wastewater treatment process of a food waste disposal plant
FIG. 2 illustrates the process of separating the extracted oil from the foreign substance by heating the temperature and purifying the oil so that it can be used as a raw material for bioenergy
As shown in Figs. 1 and 2
1. Before the food waste is dehydrated, it is effective to separate the oil from the food waste because the dehydration of the food waste is effective by lowering the viscosity of the oil due to the increase of the temperature by injecting steam (1) into the food waste.
2. The boiler tank (20) is manufactured and used by using heat oil, electric hot wire and heater rods, which is more economical than other heat sources. The heat oil is heated to heat the heating tank By circulating oil, it is possible to maintain a temperature of 100c or more.
The oil extracted through 3.3 phase centrifugal separator (3)
The temperature of the oil in the refining tank 6 is maintained at 35 ° C to 45 ° C by heating the heating oil of the heating medium boiler 20 by solidification at a low temperature and time.
4.1 Heating of the refining tank may be performed by heating the oil-water boiler (20) and heating the oil by more than 100 ° C through the heat-oil pipe in the refining tank.
5.1 The refining method of the refining tank increases the temperature of the heating oil through the heating oil boiler and slowly keeps the temperature of the refining tank (6) at only 60c ~ 70c.
6. As time passes, the temperature of the refining tank (69) is maintained at 35 to 45 ° C, and moisture and sludge are discharged out.
The oil separated by 7.2 ~ 3 times is finally boiled by heating the temperature of the refining tank to 100c or higher. After the temperature of oil in the refining tank is 35c ~ 45c, water and sludge are discharged. 10) to keep the oil.
8.1 After refining the oil in the refining tank, it is necessary to maintain the temperature of 40c ~ 45c in order to prevent aggregation of copper, vegetable protein and fine starch contained in the sesame oil.
9. In the oil tank management method of the storage tank (10), water and sludge are discharged while maintaining the temperature of 40c ~ 45c.
10. In order to maintain energy efficiency in the winter, it is necessary to maintain the temperature of the refining tanks (6, 7, 8) and the storage tank (10), the heating medium boiler (20)
11. Heat oil circulation pipe is built and installed inside the refining tank and storage tank,
To heat the oil, a thermal oil boiler (20) of 1 ton scale is made and the thermal oil oil is heated by using 4-5 electric heater rods of 15KW
12.3 The amount of wastewater from RPM and wastewater metering pump (2) is important in separating into oil, wastewater, and solids using the specific gravity difference in the phase centrifuge (3). Because the viscosity of the oil varies with the temperature difference, it is necessary to adjust the RPM of the 3-phase centrifuge and the amount of wastewater input by season. This is because of the efficiency of oil separation.
