High-gravity rectification equipment Brief introduction of high-gravity rectification products
1. High-efficiency rotary rectification machine-replacing the traditional recovery tower. Used for separation, purification and recovery of organic solvents, developed by Tianda and Zhejiang Chuangxing Chemical Equipment Co., Ltd.. (PatentNo.: ZL 214 2 771413.5) It is the first time to apply rotary distillation technology to the continuous distillation process in industrial production. The rotary rectification machine is composed of one or more rotors rotating at high speed, and gas and liquid pass through the rotors by reverse spraying to carry out mass transfer of materials.
⒉ The total height of the whole device is not more than 3.38m.. The 1.3-meter-high rectifier is equivalent to a 16-meter-high common recovery tower, which is a major breakthrough to the traditional plate tower and packed tower. Compared with the traditional column, continuous distillation has the following advantages:
① High efficiency and low energy consumption.
② Energy saving and emission reduction
3. In the high-efficiency rotary rectifier, the liquid phase has gone through the process of dispersion and aggregation for many times. During this process, the liquid is thrown away from the moving circle with concentric distribution by extremely fine droplets. Under the action of centrifugal force, the droplets moving at high speed are collided, sheared and splashed on the specific structure inside the equipment, forming a gas-liquid interface that is extremely large and constantly updated, and then enters the next cycle after being collected.
In the device, the gas-liquid two-phase flows in the rotor in reverse phase as a whole, and the gas-liquid contact process between the annular gaps of the internal structure of the device can be divided into two steps: the first step is to make cross-flow contact with the gas when the liquid phase is thrown off the center; The second step is the process that the liquid phase falls on the wall of the specific structure of the equipment. The gas in the annular space rotates upward, and the liquid rotates downward under the action of gas and gravity, which is countercurrent contact. In the second step, the rotating movement of liquid along the wall and the collision and extrusion of the constantly thrown liquid make the surface update very fast, which is similar to a series of wet-wall towers where the liquid surface updates very fast. The gas and liquid in the equipment pass through a layer of annular space as if passing through a wet-wall tower, which has higher mass transfer and heat transfer efficiency.
gravity rectification principle of gravity rectification equipment in Chuangxing Chemical Industry Co., Ltd.
(1) Centrifugal force is used to break up the liquid and then contact with the gas, which is more sufficient than direct contact with other liquids, which improves the specific surface area of contact between gas and liquid and the rate and efficiency of mass transfer and heat transfer, and greatly reduces the size of the equipment.
(2) The rotor with a specific structure rotates at a high speed in the machine body, the gas phase enters the machine from the gas inlet, enters the rotor from the outer edge of the rotor, and the liquid phase enters the rotor center from the liquid inlet, and the gas-liquid two phases form a gas-liquid interface with a large specific surface area in the rotor, which has mass transfer and heat transfer rate and efficiency. Finally, the gas phase leaves the bed through the gas outlet and is condensed by the condenser; The liquid phase is collected in the machine and led out from the liquid outlet.
Generally, it takes about 1 minutes for a high-efficiency rotary rectifier to operate normally. Users can operate intermittently or continuously according to the actual situation. In addition to conventional organic solvents, it is also advantageous to treat precious materials, heat-sensitive materials, high-viscosity materials or toxic materials. At the same time, the maintenance is convenient and no filler is needed.
Moreover, the (super gravity) distillation technology equipment replaces the traditional tower equipment, which can save steel resources and land resources for the development of society; For enterprise development, it can save resources, save energy and reduce emissions, and improve product quality. This technology has a very broad application prospect in environmental protection, medicine, high gravity desulfurization, chemical industry, pesticide, biochemical industry, material chemical industry, dye, pharmaceutical industry and so on, and is being selected by more and more users.
