Abstract

The invention belongs to the field of petroleum refining and petrochemical engineering, and particularly discloses a cooling method and cooling device for a high-viscosity heavy oil product. The cooling method comprises the steps that the high-temperature heavy oil product enters a tube pass of a water tank cooler, the high-temperature heavy oil product is discharged after being subjected to heat exchange with water in a shell pass of the water tank cooler, the water in the shell pass of the water tank cooler is heated and vaporized into water vapor, the water vapor is discharged from a vapor outlet in a vapor ascending tube or collected to an air cooler through the vapor ascending tube to be cooled, and cooled condensate water returns to the shell pass of the water tank cooler through a condensate water descending tube to form self-circulation. Through the manner of combining the water tank cooler and the air cooler, water vapor is effectively recycled, and the problems that in the prior art, water consumption is large, and the environment is prone to being polluted are solved.

Description

technical field [0001] The invention belongs to the fields of petroleum refining and petrochemical industry, and more specifically relates to a cooling method and a cooling device for high-viscosity heavy oil products. Background technique [0002] In the process of petroleum refining and refining, heavy oil is often produced. This heavy oil not only contains solid mechanical impurities such as catalyst dust, but also has the characteristics of high specific gravity, high viscosity, and poor low-temperature fluidity. In order to meet the requirements of subsequent processing or storage, it needs to be cooled. A common cooling method in the petrochemical field is to use heat exchange equipment to transfer heat between high-temperature materials and other cold media to achieve cooling, so that high-temperature materials reach a specified temperature. If the heavy material containing catalyst dust flows in the heat exchange tube at a higher flow rate, the power loss will be to...
