Cyclone separating type gas-liquid mixed phase feeding distributor

Abstract

The invention relates to a cyclone separating type gas-liquid mixed phase feeding distributor which is characterized in that a rectangular feeding structure along a tangential direction is arranged at a gas-liquid mixed phase feeding port; the rectangular feeding structure is communicated with an annular sleeve in a tower; the lower end of the annular sleeve is open; a conical funnel with holes on a panel is arranged on a tower wall at the altitude being 0.8-3 times of the altitude of the feeding port at the lower end of the annular sleeve; the conical angle is at 10-90 degrees; the diameter of the conical opening of the funnel is 0.1-1.5 times of the width of the feeding port; the middle part of the annular sleeve is closed and an annual oil collecting box is formed; a parallel flow filling layer for stabilizing flow, removing foam and self-washing is connected with the upper end of the annular sleeve; umbrella-shaped structures are arranged along the connecting lines of inner edges and outer edges of the parallel flow filling layer; and the annular width of the filling layer is 3-500 times of the interval of the filling plates.

Description

[0001] 1. Technical field [0002] The invention provides a rotary separation type gas-liquid mixed-phase feed distributor, which relates to the field of separation towers. [0003] 2. Background technology [0004] Tower internals are an important part of the packed tower, and the design of the tower internals will directly affect the performance of the packing and the performance of the entire packed tower. Together with the packing and the tower body, it forms a complete packed tower. The function of all the tower internals is to make the gas-liquid two-phase contact better in the tower, so as to maximize the efficiency and production capacity of the packing. [0005] In the homogeneous separation process of chemical industry, gas-liquid mixed-phase feed is the most commonly encountered working condition in distillation towers, such as atmospheric and vacuum distillation towers. The gas-liquid mixed-phase feed distributor is responsible for effectively separating the gas an...

Problems solved by technology

[0009] The purpose of the present invention is to overcome the deficiencies and defects of the existing gas-liquid mixed-phase feed distributor and the structure of the washing section, and to invent a rotary split-type gas-liquid mixed-phase feed distributor, which eliminates the entrainment of liquid and vapor phases, reduces the It reduces the pressure drop of the feeder, achieves a good effect of gas-liquid two-phase separation, uniform distribution of the vapor phase along the column section, reduces liquid impact, and can meet the distribution requirements of large-scale gas-liquid mixed-phase feed towers, avoiding packing and collection The coking and clogging phenomenon of the oil tank has achieved the good goal of the feeder that can stabilize the operation of the tower and improve the separation effect of the tower
