Description

Rotary multiphase reaction-regeneration combined device

This invention relates to a rotary multiphase reaction-regeneration assembly. Background technique

At present, in the field of production processes in which solids are used as catalysts or (physical or chemical) adsorbents to promote efficient fluid phase reaction, purification or concentration, etc., there is generally a problem of catalyst deactivation, thereby causing a decrease in reaction rate. And eventually the reaction process is terminated. In order to maintain the reaction continuously and smoothly, fresh solid catalyst must be continuously added to the reactor to displace the deactivated catalyst. Sometimes the catalyst is regenerable, which requires the exchange of a deactivated catalyst and a regenerated spent reactivated catalyst between the catalytic reactor and the catalyst regenerator. In another type of production process that uses a sorbent to purify a fluid material or to separate and concentrate a component of a fluid medium, it is often necessary to remove the spent absorbent that has reached saturation adsorption and place it in a specialized analytical environment. The adsorbed component is desorbed, on the one hand, the regeneration of the spent adsorbent is achieved for reuse, and on the other hand, the concentrated collection of the adsorbed component can also be achieved. This also requires the establishment of an exchange channel between the adsorption unit and the adsorbent regenerator for an inactivated adsorbent and an analytically regenerated spent revitalized adsorbent. Said solid materials which can promote the production process of interest can be collectively referred to as the reactants of the production process; after a reaction time, the reactants which lose reactivity due to various reasons can be collectively referred to as spent reactants. . The object fluid to be treated by the production process may be a gas or a liquid. In fact, when the object of the production process is a gas, the reactant may be a solid or a liquid; if it is a solid, it may be formed into any shape, such as various plates or a range of sizes. Or an irregular combination of particles.

It is common to use a timed batch loading and unloading of reactants to simplify the system, but the reaction will become unbalanced during a loading-unloading process.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view showing the structure of a rotary multiphase reaction-regeneration assembly of the present invention; and Fig. 2 is a schematic plan view of Fig. 1. detailed description

The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

The rotary multi-phase reaction-regeneration assembly device of the present invention comprises: a housing, the inside of the housing is provided with an annular receiving space 9, as shown in FIG. 1 and FIG. 2, the annular receiving space 9 is supported by On the central axis 8 of its center of rotation; the drive mechanism, the drive mechanism is capable of rotating the annular accommodation space 9 in the housing around the central axis 8 by means of an annular rack mounted on the outer ring of the bottom of the annular accommodation space 9. The driving mechanism may be an electric motor; the device further includes:

The annular accommodating space 9 is provided with a partition plate 6 arranged in the radial direction for dividing the annular accommodating space 9 into a plurality of rotor cells 3 for loading reactants or reactant components, and a plurality of rotor cells 3 The number of rotor chambers 3 is preferably 10 to 12, and more may be more, not limited thereto, and may be designed according to specific needs. The inside of the rotor chamber 3 is provided with a basket for easy replacement, and the basket is loaded with a reactant.

A reaction gas medium inlet connected to the reaction gas medium passage, a reaction gas medium outlet, a regeneration process medium inlet connected to the regeneration process medium passage, and a regeneration process medium outlet are respectively opened at the top and the bottom of the casing, wherein As shown, the reaction gas medium inlet 1, the reaction gas medium outlet 2, the regeneration process medium inlet 4, and the regeneration process medium outlet 5 are respectively opened on both sides of the center shaft 8. The cross-sectional shape of the reaction gas medium inlet 1, the reaction gas medium outlet 2, the regeneration process medium inlet 4, and the regeneration process medium outlet 5 may be circular, rectangular or the same shape as the rotor chamber 3, and is not To be limited, it is possible to achieve connectivity. The spacing between the reaction gas medium inlet 1, the reaction gas medium outlet 2 and the regeneration process medium inlet 4, and the regeneration process medium outlet 5 is not less than the circumferential width of one rotor chamber 3, thereby forming a reaction gas medium capable of avoiding The regenerative process medium passes through the isolation zone where the same rotor chamber 3 collides.

The rotary multi-phase reaction-regeneration assembly of the present invention further includes a seal for assisting sealing disposed on the partition 6 or the annular accommodation space 9. In order to facilitate the rotation, a certain gap is required between the annular accommodating space 9 and the casing, and there is a possibility that there is a certain pressure difference between the reaction gas medium and the regeneration process medium, and a cross leak may occur through the gaps. For this purpose, radial, axial, and circumferential (circumferential) seals are required to minimize cross-leakage.

The rotary multi-phase reaction-regeneration combination device uniformly places the reactants in the basket of each rotor chamber 3 in the annular accommodation space 9 when the reaction gas medium enters a certain rotor chamber 3 from the inlet.
