Embodiment 1

[0031] see figure 1 , 2 As shown, a passive high-gravity rotating bed device includes a housing 1, a rotor 3, a rotating shaft 8, a gas pipeline one 2, a gas pipeline two 4, a liquid distributor 5 and a liquid outlet 7; the liquid The outlet 7 is arranged at the lower part of the casing 1; the rotor 3 is arranged in the casing 1, and a sealing device 6 is provided between the rotor 3 and the casing 1, so that the gas and liquid entering all need to pass through the rotor; the casing 1 The bottom is provided with a groove, and a bearing 9 is arranged in the groove, and the rotating shaft 8 is fixed in the bearing 9, that is, the rotating shaft 8 is vertically arranged; in this way, the entire rotating shaft 8 is fixed in the housing 1, and the rotating shaft 8 and the housing 1 do not need to be sealed, which can reduce equipment cost; the inner edge of the rotor 3 is provided with rotor inner edge blades 10, and the outer edge of the rotor 3 is provided with rotor outer edge ...

Embodiment 2

[0035] see image 3 As shown, the embodiment 1 is repeated, the only difference is that the rotating shaft 8 is horizontally arranged in the housing 1 .

Embodiment 3

[0037] A kind of application of the device described in the above-mentioned embodiment 1 in the separation process of multiphase flow:

[0038] see Figure 4 Shown, with high pressure natural gas CO 2 Absorption as an example; using CO 2 The high-pressure natural gas with a content of 10% enters from the gas pipeline 1 to drive the outer edge blades 11 of the rotor to drive the rotor to rotate; MDEA with an absorption liquid of 40wt% enters the liquid distributor 5 from the liquid inlet, and the gas-liquid countercurrent contact completes the mass transfer process , the liquid flows out from the liquid outlet 7, and the gas flows out from the gas pipeline 2 4 . CO 2 The content is 2.5%.

Abstract

A passive supergravity rotating bed apparatus, comprising a housing (1), a rotor (3), a rotary shaft (8), a first gas conduit (2), a second gas conduit (4), liquid separators (5), and a liquid outlet (7). The rotor (3) is disposed within the housing (1) and is rotatably connected to the housing (1) by means of the rotary shaft (8). The first gas conduit (2), the second gas conduit (4), and the liquid outlet (7) are disposed on the housing (1). The liquid separators (5) are disposed at the inner edge of the rotor (3). Blades (10, 11) are provided on the inner edge of the rotor (3), the outer edge of the rotor (3), or on the inner and outer edges of the rotor (3). High-pressure fluid pushes the blades (10, 11), thereby driving the rotor (3) to rotate. Hence, no electric motor is required to drive the rotor.

Description

technical field [0001] The present invention relates to a novel passive supergravity rotating bed device, in particular to a novel supergravity device which uses the differential pressure of high-pressure fluid to drive the rotor to rotate without using a motor, and is suitable for the reaction, separation, mixing and other processes of multiphase flow , belonging to the field of hypergravity technology. Background technique [0002] In the 1870s, the British Imperial Chemical Company first proposed the concept of supergravity, and constructed a supergravity device based on this concept - a rotating packed bed. The rotating packed bed is powered by a motor, which drives the rotor to rotate at a high speed, thereby generating huge centrifugal force, using centrifugal force to simulate a supergravity environment, and realizing the strengthening of the separation process by overcoming the effect of the gravitational field on the earth. In 1983, Professor Ramshaw of the British...
