Embodiment 1

[0011] A rectification column reflux device described in this embodiment 1, such as figure 1 , figure 2 and image 3 As shown, it includes the reflux pipe 1 installed on the top of the rectifying tower 5, the reflux pipe branch is connected with a symmetrical and unconnected liquid seal pipe 4, the upper part of the liquid seal pipe is connected with the reflux pipe, and the middle and upper part of the liquid seal pipe passes through The distribution pipe 3 is connected with the lower liquid pipe 2, and the bottom of the distribution pipe is higher than the top of the return pipe. The liquid-sealed tube is provided with a liquid-sealed structure. The return pipe is always filled with liquid to ensure that the return pipe is always filled with liquid, thereby completely eliminating the possibility of hammering in the return pipe.

[0012] The reflux device is designed for the reflux of large rectification towers, so it is designed with four feeding pipes. For small rectifi...

Abstract

The invention discloses a reflux device of a rectifying tower. The reflux device comprises a reflux pipe, wherein the reflux pipe is installed on the tower top of the rectifying tower; the reflux pipe is in branch connection with symmetric and disconnected liquid seal pipes; upper parts of the liquid seal pipes are connected with the reflux pipe; middle-upper parts of the liquid seal pipes are connected with liquid falling pipes through distribution pipes; and the bottom parts of the distribution pipes are higher than the upper part of the reflux pipe. Liquid seal structures are arranged in the liquid seal pipes. The reflux pipe is always full of liquid. The reflux device of the rectifying tower is characterized in that the liquid seal pipes and the liquid seal structures in the liquid seal pipes are added in the tower of the reflux pipe; the reflux pipe is connected with the upper parts of the liquid seal pipes; the liquid falling pipes are connected with the middle-upper parts of the liquid seal structures; and the bottom parts of the distribution pipes are higher than the upper part of the reflux pipe. By adopting the structure, the reflux pipe is always full of liquid, the structure is a key for thoroughly eliminating hammering phenomenon, the condition of gas-liquid coexistence in the reflux pipe is eliminated, and the possibility of hammering phenomenon appearing due to the fact that high-temperature gas goes into the reflux pipe is completely avoided.

Description

technical field [0001] The invention relates to the technical field of a rectification tower reflux device, in particular to a rectification tower reflux device that is applied to a rectification tower and solves the problem of gas-liquid coexistence and reflux to the rectification tower. Background technique [0002] In chemical production, the use of rectification towers is very common. The operation of rectification towers cannot lack the step of top reflux, otherwise the ideal separation effect cannot be achieved; moreover, if the design of the reflux device is too simple, it will suffer unexpected When the cooled material returns to the rectification tower, due to the possibility of gas-liquid coexistence, it will cause a hammer-like abnormal sound in the return pipe, which may be large or small; the existence of abnormal sound will not only increase the operator's work Psychological burden, causing long-term vibration and impact on the packing, connecting parts and tow...
