The utility model mainly relies on the temperature-controlled condenser to complete the temperature conduction on the surface of the oil washing pipeline 1 of the current pipe section, thereby realizing the cooling control of the internal oil and gas. In order to ensure the precision control of the cooling amplitude, the utility model is provided with a circulating water condensation component and a flue gas condensation component to achieve the purpose of rapid temperature control. When it is necessary to control the variation amplitude of the condensation temperature, it can be achieved by increasing or decreasing the temperature or flow rate of the circulating water inside the circulating water condensation component; in addition, it can also be achieved by increasing or decreasing the temperature or flow rate of the flue gas inside the flue gas condensation component.

[0030] The circulating water condensation component relies on a water pump 7 as a power transmission component.

[0038] In any of the above solutions, preferably, a flue gas corrugated pipe 15 is provided in the middle of the horizontal section of each of the U-shaped flue gas pipes 12 .

[0039] The water bellows 14 and the smoke bellows 15 can achieve the purpose of telescopic control within a certain length range as needed, thereby facilitating the control of the spacing distance between adjacent annular smoke pipes 11 or annular water pipes 8 .

[0040] The annular flue gas pipe 11 and the annular water pipe 8 which are close to each other can coordinate the control of the condensation temperature of the outer wall of the oil washing pipeline 1 at the current position by controlling their internal temperatures. The coordination of the two can better achieve the purpose of precise regulation.

[0042] The purpose of the left-end screw-on flange 16 and the right-end screw-on flange 17 installed on the external threaded section of the oil washing pipeline 1 is to control the spacing adjustment of each adjacent annular water pipe 8 and annular flue gas pipe 11 by screwing them together to get closer or farther away, so as to better cooperate with each other to achieve the purpose of temperature coordination of the two to condense the outer wall of the oil washing pipeline 1.

No specific requirements are made and will not be elaborated here.

[0046] Specific working principle:

[0047] The temperature control type condenser mainly relies on the temperature control type condenser to complete the temperature conduction on the surface of the oil washing pipeline 1 of the current pipe section, thereby realizing the cooling control of the internal oil and gas to ensure the precision control of the cooling range.

[0048] In the utility model, a circulating water condensation component and a flue gas condensation component are provided to achieve the purpose of rapid temperature control. When the condensation temperature variation range needs to be controlled, it can be achieved by increasing or decreasing the temperature or flow rate of the circulating water inside the circulating water condensation component.

[0049] This can be achieved by increasing or decreasing the temperature or flow of the flue gas inside the flue gas condensation component. At the same time, the regulation of the circulating water condensation component and the flue gas condensation component can be coordinated with each other to further achieve the purpose of improving the regulation accuracy and effectively adjust the temperature of the outer wall of the oil washing pipeline 1 within the required range.

[0050] The purpose of controlling the current temperature of the flue gas and circulating water is achieved by controlling the fan 6 and the water pump 7 through the corresponding temperature controller; the fan 6 and the water pump 7 themselves can control the corresponding flue gas flow rate and the circulating water flow rate.

[0051] Specifically, when the circulating water condensation component is working, the circulating water from the external circulating water source is introduced, and the circulating water is introduced through the liquid inlet pipe 2. The circulating water continuously passes through the corresponding annular water pipe 8 and U-shaped water pipe 9, and finally passes through the liquid outlet pipe 3 at the end to be transported back to the water source. Here, the temperature of the circulating water can be heated and controlled or cooled according to the control of the temperature required for condensation. When the flue gas condensation component is working, the flue gas discharged from the external flue gas discharge pipe is introduced, and the flue gas is introduced through the air inlet pipe 5. The flue gas continuously passes through the corresponding annular flue gas pipe 11 and U-shaped flue gas pipe 12, and finally passes through the outlet pipe 4 at the end to be transported back to the flue gas discharge pipe. Here, the temperature of the flue gas can be heated and controlled again according to the control of the temperature required for condensation, or it can be directly circulated without treatment.

[0052] From the above, it can be seen that the temperature-controlled condenser adopts a circulating water condensation component and a flue gas condensation component to cooperate with each other to achieve the purpose of condensing and cooling the outer surface of the oil washing pipeline 1 in the existing process. The cooperation of the two components can effectively control the temperature; the flow direction of the circulating water and the flow direction of the flue gas are arranged relative to each other, which can ensure the control of the temperature of each annular water pipe 8 directly covering the outer wall of the oil washing pipeline 1 and the control of the temperature of each annular flue gas pipe 11, effectively ensuring the condensation and cooling of the oil washing pipeline 1 through heat conduction of the pipeline, and at the same time, the cooperation of the two can better ensure the oil flow inside the oil washing pipeline 1 Different condensation effects at different times; controlling the mutual changes in the flow rates of circulating water and flue gas can better achieve balanced control of the condensation temperature, control the circulating water flow rate and the flue gas flow rate, and achieve the purpose of controlling the condensation effect on demand; the spacing distance between each adjacent annular water pipe 8 and annular flue gas pipe 11 can be quickly adjusted by screwing together the left-end screw-in flange 16 and the right-end screw-in flange 17, and the change in the spacing distance between two adjacent annular water pipes 8 and annular flue gas pipes 11 can ensure the adjustment and control of the condensation temperature conducted inside the oil washing pipeline 1 within the current pipe section distance.
