Problems solved by technology

[0004] The technical problem solved by the present invention is to overcome the defects of the existing gas distributors that the bubbles are not uniform in size, unevenly distributed, and the bubble distribution area is small, which is easy to cause liquid phase back-mixing, and then provide a gas distributor that can obtain uniform size. , uniformly distributed small bubbles, and a large bubble distribution area, a gas distributor with a novel structure that can avoid liquid phase back-mixing and a gas distribution system including the gas distributor

Embodiment 1

[0036] Such as figure 1 As shown, the gas distributor described in this embodiment includes a gas distribution plate, and the gas distribution plate is a plate structure assembled from several corrugated sheets; please also refer to figure 2 with image 3 , the ribs of the corrugated sheet (such as figure 2 Straight line B in 1 B2 , that is, the two wave surfaces A 1 A 2 B 2 B 1 with B 1 B 2 C 2 C 1 The intersection line) is not arranged in the vertical direction, and the inclination directions of the corrugated ribs of two adjacent corrugated sheets are opposite. The material of the corrugated sheet can be selected according to the properties of the medium in the equipment. Generally, it can be various metals or alloys. When the medium is highly corrosive and the temperature is low, suitable plastics can be selected, and the medium is highly corrosive and the temperature is low. Ceramics can be selected when it is higher; when the material of the corrugated sheet...

Embodiment 2

[0042] Figure 5 Shown is the structural representation of the slurry bed reactor that the gas distribution system of embodiment 1 is installed, and the diameter of described slurry bed reactor 1 is 2000mm, and catalyst is added in the reactor from catalyst inlet 2, and liquid is located in reactor by The liquid inlet 3 at the bottom enters the reactor, and the gas enters the reactor through the gas inlet 4 at the lower part of the reactor. After being distributed by the gas distribution system, small bubbles of uniform size and uniform distribution bubble through the liquid layer, and the catalyst is in the upward direction. Under the joint action of the flowing liquid flow and the air bubbles, they are evenly dispersed in the liquid phase, or suspended in the liquid phase; the rising air bubbles enter the gas collecting hood 5 set on the upper part of the reactor, pass through the liquid surface and pass through the top of the reactor The gas outlet 6 escapes, and the liquid...

Abstract

The invention provides a gas distributor and a gas distribution system comprising the gas distributor. The gas distributor comprises at least one gas distribution disc; the gas distribution disc is of a disc type structure formed by assembling a plurality of corrugated sheets; corrugated edges of the corrugated sheets are not arranged along the vertical direction; and the inclining directions of the corrugated edges of the two adjacent corrugated sheets are opposite. According to the gas distributor provided by the invention, on one hand, air bubbles with different sizes flow through the gas distributor to from small air bubbles with similar sizes and then the small air bubbles are uniformly distributed on the whole cross section of the equipment, so that the mass transferring speed can be easily improved and the gas distributor provided by the invention has the advantages of uniform air bubble size, uniform distribution and large distribution area; and on the other hand, parameters including the composition, temperature, flow speed and the like of fluid are prone to be consistent in the radial direction of mass transferring equipment, so that the back-mixing the fluid is even avoided.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a novel gas distributor that can be used in a bubble column and a gas distribution system including the gas distributor. Background technique [0002] In petrochemical, coal chemical and other industrial production, the gas-liquid two-phase or gas-liquid-solid three-phase reactor with the liquid phase as the continuous phase and the gas phase as the dispersed phase is an important type of mass transfer equipment. Among these equipment, the slurry bed reactor, which can make the gas pass through the liquid layer suspended with solid fine particles in the form of bubbling to realize the gas-liquid-solid three-phase reaction process, has the advantages of simple structure, uniform dispersion effect, good transfer performance, and easy operation. Advantages such as convenience have received more and more attention, especially in recent years, the Fischer-Tropsch reaction o...
