Description
Technical Field
The invention belongs to the field of liquid-solid two-phase and gas-liquid-solid three-phase contact, and particularly relates to a box-cage type distribution small system and application thereof.
Background
In process engineering and many other industrial processes, multiphase flow systems are often required, including gas-liquid, gas-solid, liquid-solid, gas-liquid-solid systems, and the like. And, it is often desirable in these systems to have sufficient contact between the phases to ensure the efficiency of such systems.
Taking a liquid-solid phase system as an example, in some liquid-solid chemical reaction, the solid is present in the form of particles in a continuous liquid phase, wherein at least part of the reaction is carried out at the liquid-solid interface. In order to increase the reaction efficiency of the liquid and the solid, it is necessary to disperse the solid particles in the liquid as much as possible, so that the solid particles have a larger contact surface area with the liquid. For example, in a liquid phase catalytic reaction, a solid catalyst exists in the form of particles in a continuous liquid phase, and two or more liquid components are brought into contact with the surface of the solid particles (catalyst). In this case, in order to enhance the catalytic reaction efficiency between liquids, it is also necessary to disperse solid particles in the liquid as much as possible, so that the reacted liquid has a greater chance of coming into contact with the solid particles. If these reactions also require participants in the gas phase, the gas may also be charged, in which case a gas-liquid-solid three-phase system is formed. For example, in a certain adsorption separation process, in order to improve adsorption efficiency, it is more necessary to disperse particles in a liquid phase as much as possible, so that the adsorbent has more opportunities to contact with solutes in the liquid to perform adsorption reaction.
In a liquid-solid system as above, the solid particles involved are generally heavier than the liquid, so that when the system is at rest, the particles will accumulate at the bottom of the system and will not float up automatically. In order to disperse particles efficiently in liquids, several effective methods have been developed. At least a portion of the particles are suspended in the mixture, such as by vigorous stirring, by a strong jet of a mechanical, liquid or gas. Another effective method is to use solid fluidization. The method is to inject liquid into the liquid-solid system from the lower part of the system, creating an upward net fluid flow, resulting in particles in the system being suspended due to drag caused by the upward flow of liquid. At this point, by reasonably adjusting the liquid flow rate so that the liquid flow rate is above the minimum fluidization velocity and the minimum entrainment velocity is low, particles can be dispersed relatively uniformly within at least a portion of the space within the system. If gas is added at the bottom of the system at the same time, the upward flow of gas may also provide additional drag to assist in the suspension of the particles. At this time, the system becomes a gas-liquid-solid three-phase system.
If the solid particles involved are lighter than the fluid, the particles will float to the upper surface of the system without automatically sinking when the system is at rest. In order to disperse particles effectively in a liquid, a reverse solid fluidization method may be employed in addition to a strong agitation such as a strong jet of a machine, a liquid or a gas. The method is to inject liquid into the liquid-solid system from the upper part of the system, forming downward net fluid flow, resulting in particles in the system being suspended upside down due to drag caused by the downward flow of liquid, a phenomenon of suspension that overcomes buoyancy caused by particles lighter than liquid, sometimes referred to as reverse fluidization. At this time, by reasonably adjusting the liquid flow rate so that the liquid flow rate is higher than the minimum reverse fluidization velocity and the minimum reverse entrainment velocity is low, the particles can also be dispersed relatively uniformly in at least a portion of the space within the system. However, in this counter-fluidization condition, it will generally not make sense to add gas from above at the same time, since the gas will not flow downwards.
In many particle dispersion systems, the distribution of particles is often non-uniform. This non-uniformity is often due to the fact that the distribution of the fluid (gas or liquid) used to disperse or suspend the particles as it enters the reactor is not guaranteed to be perfectly uniform or that it does not always flow in parallel after entering, resulting in some areas that may lack fluid. In addition, the particle dispersion system has more serious and difficult control of particle distribution non-uniformity after industrial scale-up.

Detailed Description
For a better understanding of the present invention, reference will be made to the following examples.
In one embodiment, the invention discloses a small box-type particle distribution system, which comprises a shell, wherein a hollow cavity is formed in the shell, the shell is provided with a side wall, at least one of a top surface and a bottom surface is included, at least one of the side wall, the top surface or the bottom surface is provided with a through hole, and particles are arranged in the shell.
For this embodiment, the cage particle distribution subsystem obviously comprises at least one cage. In contrast to the small system, before it is used, is an external large system to which the small system is to act. In the using process of the small system, the through holes on the shell are convenient for exchanging substances between the small system and an external large system. The box-cage type particle distribution small system is small in size relatively, convenient to operate and control and capable of ensuring that production efficiency is improved under control.
Preferably, the particles have the ability to carry or carry a substance or component that facilitates the reaction.
More particularly, the particles may also include one or more micropores, with substances or components that facilitate the reaction being carried or carried in the micropores in advance. Further, the particles may also include one or more cavities in communication with the micropores, while the cavities may also include therein pre-loaded or loaded with a reaction-facilitating substance or component. The substances or components which are beneficial to the reaction can be existing in the external large system and can also be added in the external large system in advance.
In another embodiment, the sidewall is used to prevent the particles from flowing out. This embodiment ensures through the lateral wall that the granule reacts in predetermineeing the space, is convenient for control. It will be readily appreciated that the prevention herein may be a substantial portion of the prevention of the outflow of the particles.
In another embodiment: the top surface is totally enclosed or semi-enclosed, the bottom surface is totally enclosed or semi-enclosed, and top surface and bottom surface are not totally enclosed simultaneously, top surface or bottom surface prevent the granule outflow. For this embodiment, such an arrangement ensures both a uniform distribution of the particles and a reaction of the particles in the predetermined space through the top or bottom surface, as well as a exchange of fluids inside and outside the housing.
It should be noted that the shape of the housing of the cage-type and particle distribution small system can be variable, and the housing can be cube-shaped, cuboid-shaped, other polygonal shapes, cylinder-shaped, ellipse-shaped and the like; in addition to the above-described regular case, the case may be irregularly shaped, for example, when viewed from the top of the case downward, the case may be irregularly shaped in plan view. More generally, the irregular shape refers to a top-view orthographic projection of the housing in different height horizontal cross-sections that do not completely coincide. With this embodiment, different shell patterns are convenient to adapt to different reaction systems.
In addition, the invention also discloses an application of the box-type particle distribution small system: the small systems are placed in a liquid or a liquid-solid mixture, the number of small systems being one or more.
For this embodiment, since the small system includes particles capable of carrying a substance or component that facilitates the reaction, if a liquid (or gas, as will be appreciated, or both) is introduced into the small system, the particles within the small system are in a fluidized state by the fluid of the liquid (or gas, or a gas-liquid mixture phase) and are uniformly dispersed within the small system. With this, the substances or components coated on the particles move around along with the movement of the particles, thereby improving the reaction efficiency. It will be readily appreciated that the gas or liquid herein is primarily intended to cause the particles to flow, and that the liquid may be the liquid involved in the reaction itself or may be other than the reaction, provided that the liquid does not interfere with or adversely affect the reaction concerned. In general, the number of small systems is as large as possible, which is advantageous for the efficiency of the reaction, and the small systems may be cascaded or otherwise combined.
Preferably, in another embodiment: each small system is used for independently distributing liquid.
More preferably, in another embodiment: the particles can carry microorganisms at least through the surfaces thereof and are applied to sewage treatment. For this example, it is clear that the ability of the particles to be provided in sewage treatment applications is also a further limitation of the substances or components that facilitate the reaction as described above.
In another embodiment: the small system is arranged in a mixed phase of gas phase and liquid phase or a gas-liquid-solid mixed phase. For this embodiment, a mixed gas and liquid phase is introduced into the small system, and the particles in the small system are in a fluidized state under the action of the gas phase or liquid phase or gas-liquid mixed phase fluid and are uniformly dispersed in the small system.
Similarly, the number of the small systems in the gas-liquid mixed phase can be one or more.
Still further, in another embodiment: each small system is independently used for distributing gas and/or liquid. Thus, the small system forms an independent whole, is easy to operate and control, and is used for controlling the flow of particles whether the gas distribution is independent, the liquid distribution is independent, or both the gas distribution and the liquid distribution are independent.
Still further, in another embodiment: the particles comprise light particles and/or heavy particles, wherein the density of the light particles is smaller than that of the liquid phase, the density of the light particles is uniform or nonuniform, the size of the light particles is uniform or nonuniform, the density of the heavy particles is larger than that of the liquid phase, the density of the heavy particles is uniform or nonuniform, the size of the heavy particles is uniform or nonuniform, the particles are dispersed in the liquid phase, and the gas phase flows from bottom to top. It will be readily appreciated that the liquid phase environment may consist entirely of the liquid phase environment for which the reaction is intended, and may include other liquids that cause the particles to flow as described above.
Further, in another embodiment: the gas distribution device is arranged in the small system or outside the small system, and gas distribution in the small system is preferentially selected. If the gas is arranged outside the small system, a small amount of particles can be allowed to flow out, and the out-flowing particles can also have the same technical effect outside the small system. In addition, the gas is distributed outside the box and cage system, and the bottom surface of the box and cage shell can be open or large-area open, so that a large enough passage can be provided for the gas to flow through the box and cage, thereby ensuring that the small systems can be all independent reactors and can be mutually connected with the large systems in space.
Still further, in another embodiment: and for a gas-liquid mixed phase environment, coating the outer surfaces of the particles with microorganisms, and applying the particles to sewage treatment.
In another embodiment, as shown in fig. 1, the cage-type small distribution system comprises a shell, wherein a hollow cavity is formed in the shell, and at least one of the side surface, the top surface or the bottom surface of the shell is provided with a through hole, so that the system can exchange substances with the outside conveniently, particles are placed in the shell, a larger specific surface area is provided by the particles, and mass transfer between solids and fluid is enhanced.
As shown in fig. 2, a schematic structure diagram of the combined use of the small box-cage system of the present invention is shown, in a sewage tank with a length, a width and a height of 12×6×6 meters (the size is not limited, other combinations such as 24×12×8, 16×12×6 meters, etc.), a plurality of small box-cage particle distribution systems are provided, each box-cage is a complete biological sewage treatment small system, the size of the box-cage is 2×1×4 meters (1.5×1×6 meters, 1×1×6 meters, etc.), the size of the box-cage is smaller than the size of the large system in any case, a gas distributor is provided at the bottom of the box-cage or at the bottom of the large system outside the box-cage, if the gas distributor is provided at the bottom of the large system, the bottom of the box-cage can be opened or opened with a larger area, a channel with sufficient for gas to flow into the system is provided, and the small system and the air supply of the air system and the atmosphere is from a blower. Solid particles are placed in the box and the cage, and the solid particles can be light particles, heavy particles or light-heavy mixed particles. The microorganism-coated solid particles can be effectively applied to sewage treatment. Alternatively, the liquid is introduced from the side of the cage-type small system through a pump, and particles in the cage are dispersed in the system under the combined action of the gas and liquid. Because each box cage is independently air-distributed and/or liquid-distributed, the control is easy, and the production efficiency is high. To maintain the particles in suspension within the cage, the velocity of the fluid within the cage is greater than the minimum fluidization velocity of the particles and less than the minimum carry-out velocity of the particles. The so-called minimum carry-over velocity of the particles is the velocity at which the bed transitions from the fluidized bed to the transport bed. Compared with a large system, the processing efficiency of a small system is more than 5 times that of the large system, if the small systems are arranged in the required large system in sequence, the production capacity of the system can be improved by at least more than 3 times if the volume occupied by the small systems is 50% of that of the system.
In summary, the solid particles used in the cage-type small system may be light particles, heavy particles, light-heavy mixed particles. The density of the light particles is smaller than that of the liquid, and gas can be introduced into the liquid to form a gas-liquid mixture, at the moment, the density of the gas-liquid mixture is smaller than that of the liquid, and the particles can be suspended in the gas-liquid mixture by changing the gas inlet amount. The particle density of the heavy particles is larger than that of the liquid, the particles can be pushed to be suspended in the liquid through liquid or gas flow, and the light particles can be suspended at the same time through gas-liquid combined action. The mixed particles comprise light particles and heavy particles, and besides the advantages of the light particles, the heavy particles can be carried from the bottom by lower gas speed or liquid speed, so that the particles reach certain particle distribution in the vertical direction, and the space is fully utilized.
The particles can be large or small in selected size, are various in materials and shapes, are preferably large in specific surface area, are similar to spheres in shape, are close to liquid in density and are good in liquid conductivity, and when the particles are applied to sewage treatment, the particles with surfaces suitable for microorganism growth are selected as much as possible.
In another embodiment, the small box-cage system is used in other multiphase flow systems, a plurality of small box cages can be arranged at different axial or/and radial positions of the system, and each small box cage is independently operated. Overall, the arrangement of the small cage can greatly increase the inter-phase contact efficiency in the large system. The specific application is that ginkgo flavone is extracted from ginkgo leaf, and legume protein is separated and extracted.
In another embodiment, the small box-type system is used in a reactor, such as a chemical reaction system, and a plurality of small box cages can be arranged at different axial or/and radial positions of the system, so that each small box cage becomes a complete reaction system, and the small box cages are easy to control and high in mass and heat transfer efficiency, so that the purpose of locally increasing the reaction efficiency or/and the reaction intensity is achieved.
In addition, the small box cage belongs to a large reaction system, so that the effect of effectively dispersing solid particles can be achieved when the small box cage is integrally seen, and adjustment can be timely and effectively made according to the change of working conditions (such as the generation of side reaction and the increase of products), so that the reaction efficiency of the reactor is effectively improved. The specific application is as follows: liquefaction of coal, heavy oil reforming, catalytic hydrogenation, aniline preparation by catalytic hydrogenation of nitrobenzene, and the like.
