Description

Technical Field

[0001] The utility model belongs to the technical field of three-phase separation, and in particular relates to a low-temperature pyrolysis three-phase separation device. Background Art

[0002] Crude oil contains water and natural gas after being extracted from oil fields and oil wells, and needs to be separated before transportation. The purified crude oil and natural gas after treatment are exported as products, and the separated water can be used as reinjection water for oil wells. The separation of crude oil extracted from oil fields and oil wells generally uses a three-phase separator.

[0003] A three-phase separator is disclosed in the utility model patent with the announcement number CN 218811542 U, which relates to the technical field of three-phase separators, including a device body, an inlet pipe is installed at the input end of the device body, an air outlet pipe is connected to the top output end of the device body, and a drain pipe and an oil outlet pipe are respectively connected to the bottom output end of the device body, and the drain pipe is closer to the inlet pipe than the oil outlet pipe. The wave-proof mechanism can control the height of the waves rolled up by the liquid inside the device body, which can accelerate the separation of oil and water, and adjust the interlaced area of ​​the circular hole and the flow hole, so as to adjust the speed of liquid inflow, which plays a role in reducing the height of the waves. When the liquid flows into the wave-proof mechanism and the penetration buffer plate, the floating plate can further slow down the generation of waves, and the connecting rope can pull the floating plate to prevent the floating plate from moving significantly. The pyrolysis oil, gas and slag can be separated by the three-phase separator, but the pyrolysis products are mixed and difficult to separate.

[0004] Therefore, it is necessary to provide a new low-temperature pyrolysis three-phase separation device to solve the above technical problems. Utility Model Content

[0025] The cold water storage space and the hot water storage space in the water tank 1 3 and the water tank 2 4 are both provided with a water pump 1, and a water pump 2 5 is provided on one side outer wall of the housing 1;

[0026] A concave pipe 8 is installed on the outer wall of one side of water tank 1 3, and the two ends of the concave pipe 8 extend to the cold water storage space and the hot water storage space in water tank 1 3 respectively and are connected with the water pump 1 in the cold water storage space and the hot water storage space in water tank 1 3.

[0028] A concave pipe 4 11 is installed on the outer wall of the water tank 2 4 away from the concave pipe 2 9 , and a drain pipe 12 is installed on the water outlet of the water pump 2 5 , and one end of the drain pipe 12 is connected to the concave pipe 3 10 .

[0029] A water suction pipe 13 is installed on the water suction port on the water pump 2 5, and one end of the water suction pipe 13 is connected to the concave pipe 4 11. An air outlet pipe 14 and an inlet pipe 15 are installed on the shell 1, and the bottom ends of the air outlet pipe 14 and the inlet pipe 15 extend into the three-phase separator body 2.

[0036] The second step: when heating is required, the same operation as the above steps is performed, the corresponding valve is opened, water is pumped through the water pump 1 in the hot water storage space in the water tank 3, and then discharged into the temperature conducting pipe 6 through the concave pipe 8, so that the hot water flows in the temperature conducting pipe 6, thereby heating the three-phase separator body 2, and then the hot water enters the hot water storage space in the partition plate 7 through the concave pipe 2 9, and finally discharged into the hot water storage space in the water tank 3 through the cooperation of the concave pipe 4 11, the pumping pipe 13, the water pump 2 5 and the drain pipe 12, and finally the water is heated by the heating equipment to achieve the water circulation effect.
