Description
Technical Field
The invention relates to the technical field of rectification, recovery and gas-liquid mass transfer, in particular to a jet type hypergravity bed.
Background
The supergravity technology is a novel technology for strengthening gas-liquid mass transfer developed in the last 80 th century, and the working principle of the supergravity technology is that a centrifugal force field (called supergravity field for short) which is generated by high-speed rotation and is hundreds to thousands of times of gravity is utilized to replace a conventional gravity field. Under the supergravity field, the liquid is in a very fine liquid drop and liquid filament state during dispersed flying, so that the specific surface area of vapor-liquid contact is very large, the characteristics of excellent micromixing and very fast phase interface updating are realized, the gas-liquid mass transfer process can be greatly enhanced, and the height of a mass transfer unit is reduced by 1 order of magnitude. Therefore, huge tower equipment is changed into an overweight machine with the height of less than 2 meters, and the purposes of increasing efficiency, reducing volume and greatly reducing energy consumption in some occasions are achieved.
The supergravity bed is a device for applying supergravity technology to a continuous rectification process in industrial production, and can be widely applied to rectification and recovery of the following organic solvents: methanol, formaldehyde, toluene, ethanol, ethylene glycol, acetone, ethyl acetate, acetonitrile, tetrahydrofuran, dimethyl sulfoxide, methylal, n-butanol, methylene chloride, silyl ether, cyclic ethane, isobutane, isopropanol, glacial acetic acid, acetic anhydride, DMF, DMSO, DMAA, DMDA, and the like. Compared with the traditional rectifying tower, the rectifying tower has the following advantages:
1. low equipment height, low civil engineering cost and small occupied area
Because the gas phase and the liquid phase have very large contact area and collision probability under the hypergravity environment, the micromixing and mass transfer process is greatly enhanced, the mass transfer efficiency can be improved by ten times, and a huge tower is changed into a hypergravity bed with the height of less than 2 meters. A hypergravity bed with a height of 1.8 m of the body is equivalent to a common rectifying tower with a height of 15 m. Due to the advantage of the high height of the hypergravity bed, compared with the traditional rectifying tower, the civil engineering cost required for realizing the rectifying purpose is greatly reduced in the whole design scheme. The height required by the traditional rectifying tower often reaches more than 10 meters, even higher, the installation requirement is high, and a working platform of an operator is required to be provided, so that the civil engineering cost is relatively high. The height of the supergravity bed machine is only more than 2 meters (including the height of the base), and the installation requirement is low, so the civil engineering requirement is relatively simple, and the civil engineering cost is greatly reduced. The traditional rectifying tower generally needs a base and a special support, the occupied area is large, and the hypergravity bed only needs about 1-2 square of the occupied area.
In addition, the traditional rectifying tower has high requirements on wind resistance, shock resistance, lightning protection and the like due to the high height. The hypergravity bed can be installed indoors, and special protection measures in the aspects are not needed. Meanwhile, as the tower equipment is high, the high-gravity bed needs to be subjected to a certain examination and approval procedure, and the high-gravity bed is the same as other indoor equipment, and can be installed and operated after the high-gravity bed is approved by the whole project, and a special examination and approval procedure is not needed, so that more early-stage cost is saved.
2. Energy saving
The hypergravity bed has small volume and small heat dissipation area, and can save about 20 to 40 percent of energy compared with the traditional rectifying tower under the same condition according to the identification of experts.
3. Is more suitable for heat-sensitive materials
Because the supergravity bed equipment rotates at a high speed and has smaller volume, less retained feed liquid and short liquid holding time, the retention time of the feed liquid in the equipment is only about 1-2 minutes according to the running condition, and the heat-sensitive material cannot volatilize and denature in the equipment, thereby generating great economic benefit. Materials that decompose at high temperatures for long periods of time are well suited for use with supergravity beds.
4. Convenient operation
Compared with the traditional rectifying tower, the hypergravity bed has the advantages of low height, small volume and more convenience in operation relative to tower equipment. Operation of tower equipment requires operators to frequently go to the top of the tower to observe the material condition, and certain hidden danger is brought to safety production. Meanwhile, the time required from the start-up of the tower equipment to the design of the components at the top of the tower is long, the shortest time for reaching the equilibrium is usually not less than 30 minutes, and operators have to observe the operation on site in the time period. The operation observation of the supergravity bed is very convenient, meanwhile, the time from the startup of the supergravity bed to the balance is short, generally only ten minutes is needed, and operators can consider the operation of other equipment without observing beside the equipment for a long time, so that the labor intensity of operators is reduced, the labor cost is saved, and the production safety is ensured.
5. Convenient maintenance and low maintenance cost
Generally, the traditional rectifying tower needs to be overhauled once a half year, the filler needs to be cleaned every year, and each overhaul takes several days; and the hypergravity bed only needs to replace quick-wear parts such as machine seals and the like according to national standards every half year, only needs a few hours for each replacement, and has simple operation and very convenient maintenance.
6. Waste liquid discharge
Under the same conditions, the waste liquid of a common tower is discharged by about 3 percent, the hypergravity bed can meet the requirements of customers and environmental protection, the discharge can be controlled to be below 0.5 percent, and the hypergravity bed has good environmental protection effect and better social benefit and enterprise economic benefit.
Because the hypergravity bed has the advantages in various aspects compared with the rectifying tower equipment, the hypergravity bed can replace the traditional rectifying tower equipment, save steel resources for the development of the society and prolong the service life of earth resources; for the development of enterprises, the method can save site and space resources, reduce pollution emission, improve product quality, improve operation management mode, reduce production labor intensity and increase production safety. The super-gravity bed has very wide application prospect in the industries of environmental protection, medicine, chemical industry and the like, and is being selected by more and more users.
In the prior art, various types of supergravity beds exist, wherein a packed type or disc type supergravity bed can not realize a continuous rectification process in industrial production in a single device so far, although the baffled supergravity bed invented by Zhejiang industrial university and developed together with Hangzhou science and chemical engineering equipment limited company is successfully applied to the continuous rectification process in industrial production, the baffled supergravity bed has the following defects: (1) the existence of the mechanical rotor of the baffling type hypergravity bed causes the frequency of mechanical failure to be higher and the maintenance amount to be large; (2) the rotating speed of the mechanical rotor is limited by materials, machining precision and installation precision, and the supergravity amplitude of the mechanical rotor is smaller than that of jet flow, so that the working efficiency and the processing capacity of the equipment are reduced.
