Novel oil gas condensation cooling device on top of fractional distillation tower

Abstract

Provided is a novel oil gas condensation cooling device on the top of a fractional distillation tower. A floating head cover plate portion is in a shape of a groove. A baffle plate is D-shaped, the radial length of an incomplete portion is 25% of the inner diameter of a casing, and a gap between two adjacent baffle plates is 30% of the inner diameter of the casing. A floating head pipe plate is matched with a floating head flange and a hook ring matching face in a sealing mode through a trapezoid-shaped groove. The floating head cover plate of a groove-shaped structure can increase the arc depth, so that when a medium in a tube pass is reversed at the floating head position, enough baffling space is obtained, and the medium in the tube pass circulates smoothly. By arranging the baffle plate structure and gaps, flow speed of the fluid medium in a shell pass can be further increased, turbulent flow degree of fluid is improved, and a heat exchanging effect is improved. By means of the trapezoid-shaped groove, corrosion, leakage and environment pollution caused by the fact that the complexity of a corrosion environment is enhanced because of mutual leakage and mixing of the medium in the tube pass and the medium in the shell pass can be effectively avoided. In addition, by means of an LX-05 coating structure, corrosion resistance and scouring resistance can be improved, and economical loss caused by maintaining and repairing is reduced.

Description

technical field [0001] The invention relates to the fields of petroleum and chemical industry, in particular to a novel oil-gas condensation cooler at the top of a fractionation tower, which belongs to the technical field of cooling equipment. Background technique [0002] Modern chemical and petrochemical installations have the characteristics of large scale, strong continuity, high corrosion, high temperature, high pressure, flammability and explosion. Higher requirements are put forward for the reliability, stability and safety of cold replacement equipment. The condenser is a heat exchange device that uses cold fluid to cool the hot fluid part, and the temperature difference between the cold fluid and the hot fluid is relatively large. The condenser is an important process equipment in petrochemical production, and it is also an important energy-saving equipment. The operating status of the condenser plays a vital role in the safety, product quality, energy saving and e...

Problems solved by technology

Therefore, for a long time, the anti-corrosion under the hot oil medium has been solved by the metal material itself, and there are defects such as short anti-corrosion time, complicated anti-corrosion process, and high cost.

In addition, because the sealing form of the floating head tube plate, the floating head and the hook ring is too simple, there will be a problem of medium leakage, causing environmental pollution
