The number of the liquid guide grooves 2 corresponds to the number of the third overflow holes d 3.
Under the operating condition, when the liquid level in the inner groove is lower (lower than the second overflow hole d2), the liquid enters the claw type distribution pipe, when the liquid flows to the tail end, the cross ribs are hollow to discharge water, the guide claw is driven to rotate under the impact action of gravity, and under the action of centrifugal force, the liquid is thrown out along the tail end of the guide claw and is distributed on the filler in a conical shape. As the flow rate gradually increases, the inner tank liquid flows into the outer tank through the second overflow hole d2, and accumulates in the buffer zone (the space below the second overflow hole d2 and the third overflow hole d 3) between the inner tank and the outer tank. Along with the continuous increase of the flow, the buffer area between the inner groove and the outer groove is gradually full of liquid, when the liquid level is as high as the third overflow hole d3, the liquid flows into the liquid guide groove from the third overflow hole d3, and at the moment, the liquid guide groove and the flow guide claws jointly play a role in liquid distribution. When the liquid level reaches the maximum, the liquid overflows from the first overflow hole d1 and the top of the liquid guide groove simultaneously, and the liquid and the flow guide claws of the inner groove play a role in liquid distribution.
The utility model has the advantages that:
in low flow operation, the flow directing claws rotate by the force of gravity of the liquid which is sprayed onto the packing in a conical radiation pattern rather than collecting in a small area under the distributor pipe. During high flow operation, the combined action of the flow guide claw and the downcomer tank makes the area of liquid distributed on the filler wider, and meanwhile, the outer tank also provides enough stagnation space for the liquid. In addition, the claw type distribution pipe and the flow guide claws are added, so that the whole structure is more compact, and under different flow rates, the distribution of liquid is buffered, so that the distribution is more uniform under different operation states.
