Abstract
Description
Technical Field
[0001] The invention relates to a mixed gas electrostatic three-phase separator, which is mainly used for three-phase separation of oil, gas and water mixed gas produced by thermal cracking of organic materials, and can especially realize high-purity separation of oil. Background Art
[0002] The three-phase separator of mixed gas currently used in the thermal cracking of organic materials is found in the process of use that the separated oil is not of high purity and contains a certain amount of impurities such as water and carbon black, which seriously affects the direct use value of the oil. The invention relates to a mixed gas electrostatic three-phase separator which can directly separate pure oil from the mixed gas of the thermal cracking of organic materials and improve its economic value. Summary of the invention
[0003] In order to achieve three-phase separation of oil, gas and water mixed gas produced by thermal cracking of organic materials, especially to achieve high-purity separation of oil, the present invention provides a three-phase electrostatic separator for mixed gas.
[0004] The solution adopted by the present invention to solve the technical problem is: it is composed of a water collecting tray 1, an insulating ring 2, an electrode cylinder 3, an adsorption material 4, an electrode flow guide column 5, a condensing coil 6, an oil collecting cover 7, an air guide cover 8, an insulating orifice plate 9, and a tank body 10. The electrode cylinder 3 is fixed in the tank body 10 through the insulating orifice plate 9 and the insulating ring 2 to maintain insulation from the tank body 10. The insulating orifice plate 9 has a plurality of through holes. The electrode flow guide column 5 is fixed in the middle of the electrode cylinder 3 through the insulating orifice plate 9. Multiple layers of adsorption materials 4 are fixed between the electrode cylinder 3 and the electrode flow guide column 5, and they are kept in a non-contact state with the electrode cylinder 3 and the electrode flow guide column 5. The multiple layers of adsorption materials 4 are also kept in a non-contact state, and the interlayer space is connected to the through hole of the insulating orifice plate 9. The air guide cover 8 is installed in the tank body 10 and is located above the insulating orifice plate 9 and below the oil outlet C. The oil collecting hood 7 is fixed on the air guide hood 8 through multiple columns, the condensing coil 6 is coiled on the oil collecting hood 7, and the exhaust port D is located at the uppermost end of the tank body 10. The water collecting tray 1 is fixed below the air inlet A in the tank body 10, and the drain port B is located at the lowermost end of the tank body 10. The electrode cylinder 3 and the electrode guide column 5 are respectively connected to the two stages of the electrostatic generator through wires, and the wires are insulated from the tank body 10 and the air guide hood 8. The condensing coil 6 can be connected to the circulating water through the water inlet M and the water outlet N, and can also be connected to the radiator to cool the oil collecting hood 7. The mixed gas produced by thermal cracking enters the tank body 10 from the air inlet A. At this time, the valves on the oil drain port C, the drain port B, and the slag discharge port P are all closed, and the mixed gas can only be discharged from the exhaust port D. The mixed gas first enters the electrode tube 3 from the reducing port of the electrode tube 3. At this time, the airflow velocity is reduced due to the diffusion of the port. When it moves upward inside the electrode tube 3, the water molecules and polar molecular impurities such as carbon black in the mixed gas are moved laterally by the electrostatic field constructed by the electrode guide column 5 and the electrode tube 3, and are adsorbed on the surface of the electrode tube 3, the adsorption material 4, and the electrode guide column 5. Since the oil molecules are non-polar molecules, they are not attracted by the electrostatic field and are directly discharged from the holes of the insulating orifice plate 9. When the water molecules adsorbed on the surface of the electrode tube 3, the adsorption material 4, and the electrode guide column 5 are gathered sufficiently, they will drip onto the water collecting tray 1 under the action of gravity, carrying with them polar molecular impurities such as carbon black, and gather at the bottom of the tank body 10. When the liquid level accumulates to the entrance of the drain port B, the valve on it can be opened. At this time, due to the water seal effect, the mixed gas will not be discharged from the drain port B. After the water level gradually rises to the height of the drain port B, the water will automatically be discharged from the drain port B and the water level will remain unchanged. The oil and gas with impurities such as water molecules and carbon black adsorbed are discharged from the multiple through holes of the insulating orifice plate 9 and accelerated to hit the oil collecting hood 7 through the shrinkage holes of the air guide hood 8. The oil vapor condenses into oil droplets and drips outside the air guide hood 8. The condensing coil 6 cools the oil collecting hood 7 by connecting to the circulating water or radiator, further improving the condensation effect of the oil vapor. The remaining non-condensable gas bypasses the oil collecting hood 7 and is discharged through the exhaust port D.When the oil level on the air guide cover 8 is below the entrance of the oil discharge port C, the valve on it is opened, and the non-condensable gas will not be discharged from the oil discharge port C. When the oil level is higher than the oil discharge port C, the oil is automatically discharged from the oil discharge port C. The gate on the slag discharge port P is opened from time to time to discharge the slag slurry accumulated in the tank body 10.
[0005] The beneficial effect of the present invention is that the present invention can directly separate high-purity oil and non-condensable gas from the thermal cracking mixed gas. BRIEF DESCRIPTION OF THE DRAWINGS

The electrode cylinder 3 is fixed in the tank body 10 through the insulating orifice plate 9 and the insulating ring 2 to maintain insulation from the tank body 10. The insulating orifice plate 9 has a plurality of through holes. The electrode flow guide column 5 is fixed in the middle of the electrode cylinder 3 through the insulating orifice plate 9. A plurality of adsorbent materials 4 are fixed between the electrode cylinder 3 and the electrode flow guide column 5 to maintain a non-contact state with the electrode cylinder 3 and the electrode flow guide column 5. The plurality of adsorbent materials 4 also maintain a non-contact state and the interlayer space is connected to the through holes of the insulating orifice plate 9. The air guide hood 8 is installed in the tank body 10 and is located above the insulating orifice plate 9 and below the oil outlet C. The oil collecting hood 7 is fixed on the air guide hood 8 through a plurality of columns. The condensing coil 6 is wound on the oil collecting hood 7. The exhaust port D is located at the uppermost end of the tank body 10.

The condensing coil 6 can be connected to the circulating water through the water inlet M and the water outlet N, and can also be connected to the radiator to cool the oil collecting cover 7. The mixed gas generated by thermal cracking enters the tank body from the air inlet A. At this time, the valves on the oil outlet C, the drain port B, and the slag outlet P are all closed, and the mixed gas can only be discharged from the exhaust port D. The mixed gas first enters the electrode tube 3 from the reducing port of the electrode tube 3. At this time, the airflow velocity is reduced due to the diffusion of the port. When it moves upward inside the electrode tube 3, the water molecules and polar molecular impurities such as carbon black in the mixed gas are moved laterally by the electrostatic field constructed by the electrode guide column 5 and the electrode tube 3, and are adsorbed on the surface of the electrode tube 3, the adsorption material 4, and the electrode guide column 5. Since the oil is a non-polar molecule, it is not attracted by the electrostatic field and is directly discharged from the holes of the insulating orifice plate 9. When the water molecules adsorbed on the surface of the electrode tube 3, the adsorption material 4, and the electrode guide column 5 are gathered sufficiently, they will drip onto the water collection tray 1 under the action of gravity, carrying polar molecular impurities such as carbon black, and gather at the bottom of the tank body 10. When the liquid level accumulates to the entrance of the drain port B, the valve on it can be opened. At this time, due to the water seal effect, the mixed gas will not be discharged from the drain port B. After the water level gradually rises to the height of the drain port B, the water will automatically be discharged from the drain port B and the water level will remain unchanged. The oil and gas with impurities such as water molecules and carbon black adsorbed are discharged from the multiple through holes of the insulating orifice plate 9 and accelerated to hit the oil collecting hood 7 through the shrinkage holes of the air guide hood 8. The oil vapor condenses into oil droplets and gathers and drips outside the air guide hood 8. The condensing coil 6 cools the oil collecting hood 7 by connecting to the circulating water or radiator, further improving the condensation effect of the oil vapor. The remaining non-condensable gas bypasses the oil collecting hood 7 and is discharged through the exhaust port D. When the oil level on the air guide hood 8 is above the entrance of the oil drain port C, the valve on it is opened. At this time, the non-condensable gas will not be discharged from the oil drain port C. When the oil level is higher than the oil drain port C, the oil will automatically be discharged from the oil drain port C.The gate on the slag discharge port P is opened from time to time to discharge the slag slurry accumulated in the tank body 10.
