Abstract

The present application discloses a multi-region plasma shell-and-tube reactor comprising a shell body. At least two reaction regions are provided inside the shell body, and a horizontal separation panel is provided between any two adjacent reaction regions, used to separate the two and passing through the tubes. A central hole is provided in the center of any horizontal separation panel, and at least one auxiliary hole distributed around the central axis of the central hole is provided in any horizontal separation panel so as to cooperate with the central hole to cause a vortex state to be formed in a reaction region.

First claim

The invention claimed is:

1. A multi-region slurry shell-and-tube reactor, comprising a shell, wherein at least two reaction regions are provided inside the shell, a transverse partition plate is provided between the any two adjacent reaction regions, which is configured to separate any two adjacent reaction regions and pass through tube rows, a central hole is provided at the center of each transverse partition plate, an auxiliary hole distributed around a central axis of the central hole is provided in each transverse partition plate to generate a vortex state in the at least two reaction regions cooperating with the central hole, the gas-liquid mixed reactant in the at least two reaction regions ascends through the central hole due to low density while the gaseous reactant descends through the auxiliary hole due to high density, so as to form a rising and falling circulation phenomenon in the at least two reaction regions, and block the liquid reactant from circulating along an inner chamber of the shell,
wherein an inner diameter of the central hole ranges from ⅕ to ⅓ of an inner diameter of the shell,
wherein an inner diameter of any auxiliary hole ranges from 1/10 to ⅛ of the inner diameter of the shell,
wherein a first reaction region is provided at the bottom of the at least two reaction regions, the at least two reaction regions comprises the first reaction region located at a bottom end of the shell, a gaseous reactant inlet and a liquid reactant inlet are provided on a side of the first reaction region, and the liquid reactant inlet is located above ½ of a height of the first reaction region.

2. The multi-region slurry shell-and-tube reactor according to claim 1 , wherein a radial distance between the center of any auxiliary hole and the center of the central hole ranges from 0.6 to 0.8 times of the inner diameter of the shell.

3. The multi-region slurry shell-and-tube reactor according to claim 1 , wherein the number of auxiliary holes provided in any transverse partition plate ranges from 3 to 6.

4. The multi-region slurry shell-and-tube reactor according to claim 3 , wherein three to six auxiliary holes uniformly arranged in a ring shape are provided in each transverse partition plate.

5. The multi-region plasma shell-and-tube reactor according to claim 4 , wherein an axial distance between any two adjacent transverse partition plates ranges from 0.5 to 1 times of the inner diameter of the shell.

6. The multi-region slurry shell-and-tube reactor according to claim 4 , wherein in a case that a height of the shell is lower than 5 meters, two to four transverse partition plates are provided inside the shell; and in a case that the height of the shell is greater than 5 meters, at least four transverse partition plates are provided inside the shell.

7. The multi-region slurry shell-and-tube reactor according to claim 1 , wherein the number of auxiliary holes provided in any transverse partition plate ranges from 3 to 6.

8. The multi-region slurry shell-and-tube reactor according to claim 1 , wherein the number of auxiliary holes provided in any transverse partition plate ranges from 3 to 6.

9. The multi-region slurry shell-and-tube reactor according to claim 2 , wherein the number of auxiliary holes provided in any transverse partition plate ranges from 3 to 6.
