Full overflow tank type liquid distributor

Abstract

The invention discloses a full overflow tank type liquid distributor which comprises liquid distribution pipes, a buffer tank, a primary tank, liquid distribution boxes, secondary tanks, baffles, connecting plates, liquid receiving boxes and liquid guide plates, and is characterized in that the primary tank is internally provided with two longitudinal partitions parallel to two walls of the primary tank, and a designed quantity of transverse partitions; identical gaps are formed among the longitudinal partitions and the two side walls of the primary tank; the transverse partitions are arranged between the two longitudinal partitions and are perpendicular to the longitudinal partitions; a double right-angle folded plate is arranged between every two adjacent transverse partitions; each liquid distribution box combined by two wide-top and narrow-bottom rectangular cross sections is formed between each double right-angle folded plate and each transverse partition; a concave overflow port is formed at the upper edge of each double right-angle folded plate; the widths of the liquid distribution boxes and the buffer tank are identical; and liquid outflow modes of the primary tank and the secondary tanks are overflow modes, that is the outflow direction of liquid is opposite to the sedimentation directions of material granules.

Description

technical field [0001] The invention relates to an internal part of a packed tower in the chemical industry, in particular to a full overflow tank type liquid distributor. The distributor is especially suitable for the separation of materials that are prone to clogging. Background technique [0002] In the design of packed tower, the correct and good selection of packing and tower internals is related to the success or failure of the process operation, especially after the selection of equipment packing, the design of matching tower internals becomes the key to the design of packed towers. As an important part in the packed tower, the distributor is required to have good distribution effect, pressure drop, anti-clogging, low cost, and easy to manufacture and install. Therefore, the structure of the distributor plays an important role in the operation of the packed tower. [0003] Common distributor types in the prior art include pipe type, trough type, disc type and the lik...

Problems solved by technology

When the liquid is injected into the first-level tank, the liquid impacts the liquid level, and the liquid volume discharged from each distribution branch pipe is uneven, so that the liquid level is not equal. Because the static pressure of the liquid column is the driving force for the discharge of the liquid from the first-level tank and the second-level tank , so that the liquid level is not equal, so that each secondary tank cannot obtain a reasonable liquid volume; each secondary tank is also due to similar reasons, so that the liquid volume discharged from each liquid distribution hole is not uniform

At the same time, since the liquid discharge of the primary tank and the secondary tank is powered by the static pressure of the liquid column, the liquid distribution holes at the bottom of the primary tank and the secondary tank are prone to blockage

[0004] There is also a trough distributor in which the secondary tank is overflow type, and the primary tank still uses the static pressure of the liquid column as the liquid flow force. Although the secondary tank overcomes the blockage, the primary tank still has blockage, which is a A non-full overflow tank distributor, and because there is no structure to stabilize the liquid level, the liquid distribution is uneven, so the quality of the liquid distribution is still not high, and it cannot be used in high-efficiency structured packing and precision separation
