The primary purification lines are intended for extraction of mechanically incompressible contaminates from pressed plant oil. The primary purification lines are manufactured and assembled both for continuous and cyclic operation. The capacity is up to 1000 ton per day.

Description of the line of primary purification of plant oil

Raw pressed oil is accumulated in the tank Е2. For even filtering bed precoating and prevention of blockage of the discharge pipeline of the tank Е2 with sediment oil mixing is carried out by means of the mixing device of the tank Е2. Before the filtration of non-refined oil the filter should be prepared for the process. Crude oil from the tank Е2 is fed to the filter Ф3 reservoir with the pump Н1. Emergence of pure oil in the filter's run-down box Ф3 evidences the filter being filled. When the filter is filled isolation valves are switched to filtering bed precoating by oil circulation around the circuit Е2-Н1-Ф3-Е2. Emergence of pure oil in the filter's run-down box Ф3 evidences the bed being precoated. Isolation valves are switched to basic filtration (into the tank for filtered oil). When the maximum filtration pressure is reached oil feed with the pump Н1 is stopped. Non-filtered oil remained in the filtering tank is drained into the tank Е2. Filtering residue remained on the filtering plates is purged with dry air to make the residue flowable and to remove the oil. Air and oil are trapped in the trap Л4 of the vessel Е2, where the separation process takes place. Then vibrational discharge of the residue from the filter screen is carried out. To do this the bottom valve should be open and pneumatic vibrator should be switched on. The filter Ф3 is ready for operation.
