Abstract

The present invention discloses a compact double-pipe type filled tower. It possesses the successively-connected fractionation tower body lower internal core and fractionation tower body upper internal core, on the fractionation tower body upper internal core a condenser is set, the exterior of said fractionation tower body upper internal core and condenser is equipped with a fractionation tower body external cover, on the side surface of said fractionation tower body external cover are fixed a condenser outlet tube and a condenser inlet tube which are respectively close to lower end and upper end of said fractionation tower body upper internal core, the upper end of said fractionation tower body external cover is equipped with gas outlet tube, its lower end is equipped with a gas-liquid separator, and the cavity enclosed with the fractionation tower body upper internal core and lower internal core, external cover of fractionation tower body and top end of gas-liquid separator is filled with filling material.

Description

technical field [0001] The invention relates to a rectification device, in particular to a compact sleeve-type packed tower. Background technique [0002] Packed towers are widely used in the separation of components in chemical industry, light industry and low temperature industries. In recent years, self-cascading mixed refrigerant refrigerators using mixed refrigerants in the cryogenic field have developed rapidly, and single-stage compression can achieve a refrigeration temperature of -40 to -200 °C. Compared with the traditional cascade compression refrigeration system, the structure of the refrigerator is greatly simplified, which greatly reduces the manufacturing cost and maintenance cost, and has a very broad application prospect. [0003] However, in the temperature range below -60°C, if the lubricating oil enters the low-temperature part of the refrigerator with the refrigerant, it will solidify and block the throttling hole of the throttling element, making the r...
