Embodiment

[0022] A spin-splitting gas-liquid mixed-phase feed distributor is integrated by the following structure: the gas-liquid mixed-phase feed inlet (2) is a rectangular feeding structure in the tangential direction, and the ratio of height to width is 2-15:1. The inner annular sleeve (3) of the body (1) is connected; the lower end of the annular sleeve (3) is open, and the annular cross-sectional area accounts for 5%-80% of the cross-section of the tower, and the annular sleeve (3) is along the inner wall from top to bottom. It is a cylindrical or conical structure; the distance from the lower end of the annular sleeve (3) is 0.8-3 times the height of the feed inlet (2) and the tower wall is provided with a conical funnel (4) with a hole in the plate surface, and the cone angle is 10°- 90°, the diameter of the cone opening of the funnel (4) is 0.1-1.5 times the width of the feed inlet (2); the middle part of the annular sleeve (3) is closed to form an annular oil collection tank (5...

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...
