Background
The column vessel is often in need of multistage liquid phase feed and intermittent withdrawal of material. When the upper liquid phase material is required to be extracted, the liquid phase collection function is required to be provided; when the upper liquid phase material is not required to be extracted, the equipment is required to have the function of redistributing the upper liquid phase material, and if the liquid phase material is allowed to overflow freely, the lower distribution effect can be influenced, the efficiency of lower packing is influenced, and even local flooding is caused. Conventional liquid redistributors can perform the function of collecting the upper liquid phase and redistributing it again, but are not suitable for the extraction of materials. On the one hand, a stable liquid level is required when the material is extracted, and on the other hand, the gas phase is prevented from being carried out, and a sufficient liquid level is required. The liquid redistributor has higher requirements on groove depth, and has the advantages of high processing difficulty, high manufacturing cost and inconvenient maintenance.
The common material extraction switching method generally performs forced extraction and recovery through a control valve and an instrument outside the tower. A collector and a liquid distributor are arranged between the two stages in the tower, and the materials are extracted from the collector in the tower when the materials need to be extracted; when not needed, the materials pumped out of the tower are sent back to a lower liquid distributor in the tower through accessories such as a control valve and the like, so that liquid phase redistribution is realized; even the extracted materials are directly discharged, so that energy consumption waste is formed. The method has the advantages of complex control, high cost and more hidden trouble. To this end, a dual mode liquid collection and distribution device is designed to overcome the above-described problems.

The invention aims at being completed by the following technical scheme: the double-mode liquid collecting and distributing device comprises an upper-level filler, a lower-level filler and a distributing device arranged in the middle, wherein the distributing device consists of a collector, a downcomer, a liquid collecting cylinder and a liquid distributor, the collector is arranged below the upper-level filler in a concave structure, the end part of the collector is provided with the downcomer, the liquid collecting cylinder is arranged below the collector, and the downcomer is communicated with the collector and the liquid collecting cylinder; the liquid distributor is arranged below the liquid collecting cylinder, a communicating vessel is arranged at the high position of the liquid collecting cylinder and is connected with the liquid distributor through the communicating vessel, and one side of the liquid collecting cylinder is provided with a suction opening; a lower-stage feeding pipe is arranged above the liquid distributor and on the communicating vessel.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
In the embodiment 1, as shown in the attached figure 1, the gas-phase material enters the upper-level packing 1 from bottom to top through the gaps of the liquid distributor, the liquid collecting cylinder and the collector; the liquid phase material falls from the surface of the upper-level packing 1 from top to bottom and is collected by the collector, the liquid phase material is collected in a channel of the collector, is guided into a liquid collecting cylinder at the lower part through a downcomer, and the liquid phase material is continuously extracted to the outside of the tower through a pumping port, so that the liquid level in the liquid collecting cylinder is maintained at a low level, and the upper-level liquid phase is completely discharged from the pumping port and does not enter the lower-level packing. The lower-level liquid phase material enters a liquid distributor from a feed pipe and is sprayed on the lower-level filler surface 9 through a spray hole; the upper and lower liquid phase materials are not affected each other.
In example 2, example 1 further, the amount of the extracted upper-level material is reduced, the liquid level in the liquid collecting cylinder starts to rise when the amount of the extracted upper-level material is less than the amount of the fed upper-level liquid phase, and when the liquid level reaches the opening position of the communicating vessel, part of the upper-level liquid-phase material starts to enter the communicating vessel, and the material directly enters the lower-level liquid distributor through the communicating vessel under the influence of gravity. The upper and lower liquid phase materials are mixed in the liquid distributor and finally sprayed on the surface of the lower filler through the spraying holes.
In the embodiment, the liquid distributor can freely select a porous tubular distributor with a pressure type being dominant or a trough distributor with a gravity sedimentation type being dominant according to requirements, and the resistance of the liquid distributor due to the change of the feeding amount load can be automatically adjusted through the liquid level height in the communicating vessel without manual intervention.
In the embodiment, under the double-mode operation mode of extraction and non-extraction, the liquid level of the device is automatically controlled, a complex external control system is not needed, the process is simple, the reliability is high, and the comprehensive cost is low.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention.
