[0017] Compared with the prior art, the petroleum refining high-efficiency condenser has the advantages that:

[0018] 1.

[0019] 2. After the high-temperature oil gas is dispersed, the high-temperature oil gas enters the inside of the intermediate cylinder pipe and the side cylinder pipe, the internal thread groove arranged in the inside of the intermediate cylinder pipe and the side cylinder pipe enables the high-temperature oil gas to stay for a longer time when passing through, and the internal thread groove also enables the high-temperature oil gas to rotate, so that the inner wall of the intermediate cylinder pipe and the side cylinder pipe does not remain much oil to cause the condensation effect to decrease, and the outer heat dissipation ribs on the outer surfaces of the intermediate cylinder pipe and the side cylinder pipe enable the intermediate cylinder pipe and the side cylinder pipe to be cooled faster, improve the condensation effect of the high-temperature oil gas, and enable more oil to be condensed;

[0020] 3. After condensation, the high-temperature oil and gas will be blocked by the top cover and the dispersion guide shell, preventing the high-temperature oil and gas from being directly discharged from the top cover. This prolongs the residence time of the high-temperature oil and gas in the top cover, allowing more of the remaining oil in the high-temperature oil and gas to be collected. The inclined design of the dispersion guide shell allows the oil to be better concentrated, making it easier for the oil to be discharged from the drain port, and allowing the oil in the high-temperature oil and gas to be condensed more fully.

[0042] The receiving mechanism comprises a dispersion guide shell 11, the dispersion guide shell 11 is located between the cylinder shell 1 and the top cover 3, the outer surface of the dispersion guide shell 11 is fitted with the outer surfaces of the top cover 3 and the cylinder shell 1 respectively, and the cylinder shell 1 and the dispersion guide shell 11 are concentrically designed, the outer surface of the dispersion guide shell 11 is designed to be inclined, the side surface of the top cover 3 is provided with the liquid discharge port 15, and the height of the liquid discharge port 15 is the same as the lowest part of the inclined surface of the dispersion guide shell 11.
