Embodiment 1

[0022] When the stirring extraction hopper 2 is started, add 100 kg of Luojiang Oil and Gas Development industrial waste diesel oil with a solid phase content of 15% by mass, seal the charging port after the nitrogen is emptied, start the stirring device of the stirring extraction hopper and store the solvent through nitrogen. The solvent in the tank is pressed into the stirring extraction hopper, and the solvent is fully contacted with the waste oil in the extraction hopper under stirring, and kept for 15 minutes, the centrifuge 3 and the screw conveyor 5 are started, and the solid material is separated from the screw conveyor 5, and the liquid material is passed through The feeding pump 4 is pumped into the rectification tower 6, and in the rectification tower, the solvent is evaporated from the top of the tower because the boiling point is lower than that of diesel oil, and enters the water washing tower 7, and the bottom of the rectification tower 6 obtains a recycled indust...

Embodiment 2

[0025] When the stirring extraction hopper 2 is started, add 100 kg of industrial waste diesel oil at the bottom of the tank with a solid phase content of 8% by mass, seal the charging port after the nitrogen is evacuated, start the stirring device of the stirring extraction hopper and discharge the solvent from the solvent storage tank by nitrogen. The solvent in the extraction hopper is pressed into the stirring extraction hopper, and the solvent is in full contact with the waste oil in the extraction hopper under stirring, and kept for 15 minutes. Start the centrifuge 3 and the screw conveyor 5 to separate the solid material from the screw conveyor 5, and the liquid material is pumped into the rectification tower 6 through the feeding pump 4, and the solvent in the rectification tower is evaporated from the top of the tower because the boiling point is lower than that of diesel oil. , into the water washing tower 7, the bottom of the rectifying tower 6 to obtain recycled ind...

Embodiment 3

[0027] When the stirring extraction hopper 2 is started, add 100 kg of industrial waste diesel oil at the bottom of the tank with a solid phase content of 8% by mass, seal the charging port after the nitrogen is evacuated, start the stirring device of the stirring extraction hopper and discharge the solvent from the solvent storage tank by nitrogen. The solvent in the extraction hopper is pressed into the stirring extraction hopper 2, and the solvent is fully contacted with the waste oil in the extraction hopper under stirring, and kept for 30 minutes. Start the centrifuge 3 and the screw conveyor 5, separate the solid material from the screw conveyor 5, and the liquid material is pumped into the rectifying tower 6 through the feeding pump 4, and in the rectifying tower 6, the solvent is evaporated from the top of the tower because the boiling point is lower than that of diesel oil. out, enter the water washing tower 7, and the bottom of the rectifying tower 6 obtains the recyc...

Abstract

The invention provides a device for extracting industrial waste oil containing solid particles and a usage method thereof. The device is characterized by consisting of a solvent storage tank, a stirring-extracting hopper, a centrifugal machine, a feeding pump, aspiral conveyor, a rectifying tower, a water scrubbing tower, a solvent steam condenser, an oil-water separator and a water chiller. The inlet end of the solvent storage tank is connected with a solvent pipeline and a nitrogen inputting pipeline, and an outlet pipeline is connected to the stirring-extracting hopper. A stirring device is arranged in the middle of the stirring-extracting hopper, and the lower end of the stirring-extracting hopper is connected with the centrifugal machine. The lower end of the centrifugal machine is connected with the feeding pump, the feeding pump is connected with the rectifying tower, a regenerated oil outlet is formed in the lower end of the rectifying tower, and a pipeline connected to the bottom of the water scrubbing tower is arranged at the upper end. A pipeline connected to the solvent steam condenser is arranged at the top of the water scrubbing tower, and the bottom of the tower is connected with the oil-water separator. A pipeline connected to the stirring-extracting hopper is arranged at the upper portion of the oil-water separator, a pipeline led to a cooling box is connected to the lower portion, and a pipeline connected with the water scrubbing tower is arranged at the upper portion. The device can conduct extracting and recovering treatment on industrial waste oil containing solid particles.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a device for extracting industrial waste oil containing solid particles by a solvent method and a use method thereof. Background technique [0002] The harmless treatment methods of industrial waste oil containing solid particles mainly include biological, physical and chemical methods. The biological method is more practical for industrial waste oil with low oil content, but the degradation cycle is longer. Physical treatment of industrial waste oil containing solid particles has the characteristics of simple process, but the oil content of solid particles after treatment is generally about 5%. The chemical method to treat industrial waste oil containing solid particles is mainly the solvent method, which has the characteristics of good treatment effect, but has the disadvantages of long process flow and secondary treatment of oily wastewater. Especially in the design of extrac...
