Description

Rectifying column liquid trap of easily installing

Technical Field

The utility model relates to a rectifying column liquid trap technical field specifically is a rectifying column liquid trap of easily installing.

Background

The rectifying tower is a tower-type gas-liquid contact device for rectifying. By utilizing the property that each component in the mixture has different volatility, namely the vapor pressure of each component is different at the same temperature, the light component (low-boiling-point substance) in the liquid phase is transferred into the gas phase, and the heavy component (high-boiling-point substance) in the gas phase is transferred into the liquid phase, thereby realizing the purpose of separation. The rectifying tower is also a mass and heat transfer device which is widely applied in petrochemical production. The rectifying column is easy to generate wall flow during operation, the wall flow is uniformly distributed in the whole rectifying column by generally installing a redistributor in the rectifying column, but the redistributor is not easy to install in the rectifying column with smaller column diameter, for example, the rectifying column with the diameter smaller than 300mm is not easy to install the redistributor, so that the wall flow in the rectifying columns with smaller column diameter can flow to the bottom of the column along the column wall, the liquid reflux amount on the filler is greatly reduced, and the purity of products on the top of the column is reduced. At present, in order that the wall flow in a rectifying tower with a smaller tower diameter cannot flow to the bottom of the tower along the wall flow of the tower, a circle of baffles are arranged in the tower body at certain intervals to serve as liquid collectors, and the wall flow is guided to the filler below through the baffles, so that the liquid flow on the filler is increased.

However, the existing liquid collector is mainly characterized in that the flanging is arranged at the top end of the liquid collector and is arranged on the inner wall of the rectifying tower, but the flanging is perpendicular to the inner wall of the rectifying tower, so that the flow guiding effect cannot be achieved, part of liquid can be gathered on the flanging, and then the liquid flows into the bottom of the tower along a gap between the flanging of the liquid collector and the inner wall of the rectifying tower, the purity of a product is influenced, and in addition, the existing liquid collector can only guide wall flow to a filler in a certain specific direction, and the liquid cannot be uniformly distributed.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, in an embodiment of the present invention, an easy-to-install liquid trap for a distillation column includes: the liquid collector 1 comprises an outer wall 11 and an inner wall 12, the outer wall 11 is in a circular truncated cone shape with the diameter gradually decreasing from top to bottom, the inner wall 12 is in a circular truncated cone shape with the diameter gradually increasing from top to bottom, a liquid collecting tank 13 is arranged in an area between the outer wall 11 and the inner wall 12, the mounting table 2 is arranged in the middle of the outer side of the outer wall 11, the mounting table 2 is matched with a mounting seat 3 on the inner wall of the rectifying tower, the liquid collector 1 is mounted in the mounting seat 3, the edge of the outer wall 11 is abutted against the inner wall of the rectifying tower, meanwhile, the edge part is provided with a flow guiding slope 111 inclining inwards, and as the flow guiding slope 111 is tightly attached to the inner wall of the rectifying tower, when wall flow exists, the wall flow can directly flow into the liquid collector 1 along the flow guiding slope 111, so that the wall flow is collected on the mounting table 2 due to the fact that the mounting table 2 is arranged on the top of the, from the gap to the bottom of the tower.

The bottom of the liquid collecting tank 13 is provided with a liquid leakage hole 131, the inner wall 12 is provided with an overflow hole, the overflow holes comprise a low water level overflow hole 121 and a high water level overflow hole 122, the liquid leakage hole 131, the low water level overflow hole 121 and the high water level overflow hole 122 are all provided with a diversion strip 14, the diversion strips 14 can be hollow round tubes or absorbent cotton cloth, when the diversion strips 14 are hollow round tubes, when less liquid exists in the liquid collecting tank 13, the liquid can be uniformly divided into a plurality of sub-flows from the flow guide strips 14 at the liquid leakage holes 131 to the filler, when the liquid level in the liquid collecting tank 13 reaches the low-level overflow hole 121, the liquid is uniformly divided into a plurality of sub-flows from the flow guide strips 14 at the two positions of the liquid leakage hole 131 and the low-level overflow hole 121 to flow to the filler, when the liquid level in the liquid collecting tank 13 reaches the high-level overflow hole 122, the liquid can be uniformly divided into a plurality of component flows to the filler from the liquid leakage hole 131, the low-level overflow hole 121 and the flow guide strips 14 at the three positions of the high-level overflow hole 122.
