A separation device includes a membrane separation module (), an adsorption module (), and a gas intake module (). The membrane separation module includes a first housing (), and a membrane assembly () disposed in the first housing. The first housing has a first gas inlet (), a first gas outlet (), and a retentate gas outlet (). The membrane module has a permeate gas outlet, the permeate gas outlet being in communication with the first gas outlet. The adsorption module has a second housing () and an adsorbent layer () disposed in it. The second housing is disposed on the first housing and has a second gas inlet (), a second gas outlet (), and a desorption gas outlet (). The second gas inlet is in communication with the first gas outlet. The gas intake module has a third gas outlet () in communication with the first gas inlet.

Separation device and separation method

A dividing wall column (), comprising: a partition plate () arranged along an axial direction of the dividing wall column (); a first shaft () arranged along a radial direction of the dividing wall column (), and a first splitter plate () with an end connected to the first shaft (), which are both placed beneath the partition plate (), wherein the first splitter plate () is configured to be pivotable around the first shaft (), so as to control distribution of a stream from below the first splitter plate () into spaces formed at two sides of the partition plate (); and a second shaft () arranged along the radial direction of the dividing wall column (), and a second splitter plate () with an end connected to the second shaft (), which are both placed above the partition plate (), wherein the second splitter plate () is configured to be pivotable around the second shaft (), so as to control the stream from above the second liquid splitter plate () into the spaces formed at two sides of the partition plate ().

Divided-wall column

The present disclosure provides a reactor for at least two liquid materials, comprising an enclosed reactor housing; a feeding tube having liquid material inlets for receiving corresponding liquid materials respectively; a distribution tube communicating with the feeding tube and extending into the reactor housing, the distribution tube being provided with a plurality of distribution holes in the region thereof extending into the reactor housing; a rotating bed in form of a hollow cylinder, which is disposed in the reactor housing via a fixing mechanism, thus dividing inner cavity of the reactor housing into a central area and an outer area, the rotating bed being capable of rotating driven by a driving mechanism; and a material outlet provided in a lower portion of the reactor housing for outputting product after reaction. The distribution tube extends into the central area spaced from inner surface of the rotating bed, so that materials can enter into the outer area from the central area through the rotating bed and can be output via the material outlet.
