Embodiment 1

[0025] A new type of long-axis magnetic pump reactor, such as figure 1 As shown in the figure, a long shaft runs through the reactor, the long shaft is wrapped by a long sleeve, and a bearing is installed inside to completely isolate the shaft and the bearing from the outer medium. The principle of the magnetic pump is used to immerse the blade in the medium. Coupled with the shaft to achieve the effect of stirring, the gas riser is arranged on each tray in the reactor, the air inlet of the gas riser is set on one side of the long axis of the reactor, and a gas distributor is connected to the upper part of the gas riser, and the center of the gas distributor falls on the side of the long axis of the reactor. On the long axis, the gas phase from the lower tray is evenly sprayed into the liquid-solid mixture on the tray through the gas distributor. Each tray is provided with liquid phase inlet and outlet facilities, and liquid phase inlets are set on both sides of the tray. and ...

Abstract

The invention relates to a novel long-shaft magnetic pump type reactor and mainly solves the problem of uneven mixing of gas, liquid and solid in the prior art. The novel long-shaft magnetic pump typereactor is adopted, the reactor is penetrated through by 1-2 long shafts, the long shaft is wrapped by a long sleeve, a bearing is additionally added in the inner part of the long shaft, the shaft and the bearing are completely isolated from a medium on the outer side, a paddle soaked in the medium is coupled with the shaft through the principle of a magnetic pump, the stirring effect is achieved, a standpipe is distributed on each layer of column plate in the reactor, an air inlet of the standpipe is arranged on one side of the long shaft of the reactor, the upper part of the standpipe is connected with a gas distributor, the center of the gas distributor is arranged on the long shaft, a gas phase from the column plate on the lower layer is evenly sprayed into a liquid solid mixture on the column plate through the gas distributor, the technical scheme that each layer of the column plate is provided with liquid phase inlet and outlet facilities better solves the above problem, and thenovel long-shaft magnetic pump type reactor can be used in the catalytic reaction distillation of the gas-liquid-solid three phases.

Description

technical field [0001] The invention relates to a novel long-axis magnetic pump type reactor. Background technique [0002] With the rise and development of green chemical industry, chemical process enhancement technology has attracted more and more attention. Reactive distillation technology, which integrates chemical reaction and rectification separation to form a multifunctional reaction device, is one of the ways to achieve chemical process enhancement. Catalytic rectification is a heterogeneous catalytic reactive rectification technology developed on the basis of homogeneous reactive rectification. In this technology, solid catalysts are placed on each layer of trays in the reaction section of the tower, and gas and liquid are upward and downward respectively. With countercurrent flow, the chemical reaction and rectification separation are highly coupled in the tower, which can continuously remove the reaction products, and the reaction heat can also be used as the vap...
