Description

Technical Field

[0001] This utility model belongs to the field of sugar alcohol equipment technology, and specifically relates to a distributor for chromatographic columns. Background Technology

[0002] In the production and refining of sugar alcohols, separation and purification also require chromatographic separation devices. These devices typically consist of 8 to 30 chromatographic columns connected in series, offering advantages such as strong separation capacity and ease of automation. The chromatographic device utilizes the varying adsorption capacities of different solutes in the material on the adsorbent resin. Therefore, under the action of the eluent water, the separated materials are discharged at different times, achieving the desired separation effect. Thus, to minimize the amplification effect caused by poor liquid distribution when the material initially enters the column, fully utilize the packing efficiency, and maximize the separation effect, a liquid distributor must be installed at the inlet to evenly distribute the liquid on top of the packing layer. The quality of the initial liquid distribution not only affects the separation efficiency but also the purity of the separated substances. Therefore, the liquid distributor is a crucial internal component within the chromatographic separation column. There are various types of distributors, and the selection is mainly determined by factors such as feed quality, operational flexibility, throughput, and column pressure. Initially, perforated elliptical disks were used for material distribution within the column, but these distributors are often too small, resulting in no material distribution along the column edges.

[0003] Currently, the most commonly used type is the 304 stainless steel pipe-type liquid distributor. This type of liquid distributor uses the pump head or high liquid level to directly deliver the liquid to the packing material through a pipe connection. This distributor is suitable for pressurized liquid feeding, but if the liquid level is too high, it can cause mist entrainment; if the liquid level is too low, it will cause uneven liquid distribution. Furthermore, if used for high-viscosity materials, the distributor outlet is prone to clogging, resulting in uneven material distribution. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a distributor for a chromatographic column, which makes the distribution range of the chromatographic separation liquid large and the distribution uniform.

[0005] This invention is implemented as follows: a distributor for a chromatographic column is provided, including a feed pipe, one end of which is connected to the feed end of the chromatographic column, and the other end of which is connected to a distributor seat. Multiple branch pipes are arranged on the periphery of the distributor seat, one end of each branch pipe is connected to the feed pipe through a through hole in the distributor seat, and each branch pipe is made of steel pipe wound into a tubular shape, and a gap is provided between two adjacent turns of the wound pipe to facilitate the overflow of the liquid to be separated by chromatography.

[0006] Furthermore, each of the aforementioned branch pipes is integrally hexagonal prism-shaped.

[0007] Furthermore, eight branch pipes are evenly arranged around the periphery of the distributor seat.

[0008] Furthermore, the steel pipe used for winding is made of stainless steel.

[0009] Furthermore, the other end of the branch pipe is sealed.

[0010] Compared with existing technologies, the distributor for chromatographic columns of this invention includes a feed pipe, one end of which is connected to the feed end of the chromatographic column, and the other end of which is connected to a distributor seat. Multiple branch pipes are arranged around the periphery of the distributor seat, one end of each branch pipe being connected to the feed pipe through a through-hole in the distributor seat. Each branch pipe is made of steel pipe wound into a tubular shape, and a gap is provided between adjacent turns of the wound pipe to facilitate the overflow of the chromatographically separated feed liquid. This invention is not only simple in structure, low in cost, easy to operate, and highly practical, but also provides a wide feed liquid distribution range and uniform distribution.

[0013] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0014] Please refer to the following at the same time Figure 1 as well as Figure 2 As shown, a preferred embodiment of the distributor for the chromatographic column of this utility model includes a feed pipe 1, one end of which is connected to a distributor seat 2, and a plurality of branch pipes 3 are arranged on the periphery of the distributor seat 2.

[0015] One end of each branch pipe 3 is connected to the feed pipe 1 through a through hole (not shown in the figure) provided in the distributor seat 2. Each branch pipe 3 is made of steel pipe wound into a tubular shape, and a gap 4 is provided between two adjacent turns of the wound pipe to facilitate the overflow of liquid.

[0016] Each of the branch pipes 3 is generally hexagonal prism in shape, and the cross-sectional shape of the branch pipe 3 is hexagonal.

[0017] like Figure 2 As shown, eight branch pipes 3 are evenly arranged on the periphery of the distributor seat 2.

[0018] The steel pipe used for winding is made of stainless steel.

[0019] The other end of the branch pipe 3 is closed, and the height of the closed end is not higher than the height of the connection end with the distributor seat.

[0020] Please refer to the following at the same time: Figure 1 as well as Figure 2 As shown, the distributor of this invention is used as follows: the feed solution to be separated by chromatography enters the distributor seat 2 through the feed pipe 1, and then enters multiple branch pipes 3 arranged around the periphery of the distributor seat. The feed solution is dispersed and overflows into the chromatographic column through the gaps between the winding pipes, and the branch pipes 3 disperse the feed solution in all directions within the chromatographic column. This invention not only makes the feed solution evenly distributed, further improving the separation efficiency of chromatography, but also saves production costs.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
