Centrifugal rotational flow defomaing type gas-liquid mixture feeding distributor

Abstract

The invention relates to a centrifugal rotational flow defomaing type gas-liquid mixture feeding distributor, which is characterized in that a gas-liquid mixture feeding inlet is of a rectangular feeding structure in a tangential direction and is communicated with an annular sleeve in a tower; the lower end of the annular sleeve is opened; an annular grating filler capable of decelerating, absorbing energy and degassing is arranged at a position, which is 200 to 1500mm away from the lower end of the annular sleeve; the height of the annular grating filler is 50 to 100mm; the width of the annular grating filler is 0.3 to 2.5 times of the width of the annular sleeve; the middle part of the annular sleeve is sealed to form an annular oil collecting tank; a cocurrent flow filler layer capable of flow stabilizing, defomaing and self-washing is connected to the upper end of the annular sleeve; ligatures of an inner edge and an outer edge of the concurrent flow filler layer are respectively of an umbrella-shaped structure; the annular width of the filler layer is 3 to 500 times of a clearance of filler plates.

Description

[0001] 1. Technical field [0002] The invention provides a centrifugal cyclone defoaming type gas-liquid mixed-phase feed distributor, which relates to the field of separation towers. [0003] 2. Background technology [0004] The internals of the tower are an important part of the packed tower or the plate tower. It forms a complete packed tower or the packed tower together with the tower body and the tray or the packing. The function of all the tower internals is to make the gas-liquid two-phase flow Better contact in the tower, in order to maximize the efficiency and maximum production capacity of the packing or tray, the design of the tower internals will directly affect the performance of the packing or tray and the performance of the entire packed tower or tray tower. [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 dis...

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 centrifugal cyclone defoaming type gas-liquid mixed-phase feed distributor, which eliminates the liquid phase and vapor phase Entrainment 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 section of the tower, and can meet the distribution requirements of large gas-liquid mixed-phase feed towers, avoiding fillers and oil collection tanks The phenomenon of coking and clogging eliminates the biggest bottleneck that restricts the long-term safe operation of the washing section, and achieves the goal of a good feeder that can stabilize the operation of the tower and improve the separation effect of the tower
