Description
Technical field
The present invention relates to a kind of high-speed centrifugal rectifying tower, particularly a kind of multilayer heterogenic baffling ring high-speed centrifugal rectifying tower.Rectifying, absorption that can be widely used in industries such as petrochemical industry, pharmacy, chemical industry, light industry etc. relates to the process of gas-liquid contact mass transfer.
Background technology
Rectifying and absorption are the typical unit operations of separating liquid mixture, realize by quality transmission between the liquid and gas of counter current contacting and energy transmission.Tower is the gas-liquid mass transfer (contact) equipment that can realize rectifying and absorb two kinds of lock out operation.Its version can be divided into plate column and packed tower two big classes basically.Reasonably the plate column superficial linear velocity in a column is higher, thereby production capacity is bigger, and plate efficiency is stable, and cost is low, and it is convenient to overhaul, clear up, and is the extensively employing of industrial institute.But the tower height is generally higher, and mass-transfer efficiency is little relatively.
High-gravity rotating bed is a kind of novel gas-liquid mass transfer apparatus that grows up last century, the reverse gas-liquid that enters revolving bed produces great centrifugal force and carries out mass transfer under the drive of centrifugal action, can enlarge markedly the mass transfer ability of process, reduce device height simultaneously.At present, be applied to the high-gravity rotating bed two big classes that mainly comprise in rectifying field, a class is the centrifugal rectifying column of packing type, and a class is the centrifugal rectifying column of baffling type.The centrifugal rectifying column subject matter of packing type is that gas and the liquid time of staying in filler is too short, gas can not fully contact with liquid, has reduced the efficient of mass transfer, and the centrifugal rectifying column of packing type mostly is individual layer simultaneously, its number of theoretical plate is limited, and operating flexibility is less relatively.The time of contact that the centrifugal rectifying column of baffling type has prolonged the gas-liquid phase with contact distance, mass-transfer efficiency significantly improves.Be disclosed in the Chinese patent CN1415396A on May 7th, 2003, the CN1686591A that is disclosed on October 26th, 2005 has introduced several baffling type baffling circle centrifugal rectifying towers with opening in the CN101254357A on September 3rd, 2008, can multilayer connect, increasing gas-liquid contacts the time, operating flexibility is bigger, and pressure drop is relatively low.The disturbance of fluid was out of condition when but wherein gas-liquid contacted, and mass-transfer efficiency is relatively low, and stabilization of equipment performance is not good, was not easy to determine the number of theoretical plate simultaneously, was unfavorable for the design of rectifying column size.
Summary of the invention
The objective of the invention is to overcome the above-mentioned shortcoming of existing baffling circle centrifugal rectifying tower, under the prerequisite of a small amount of increase pressure drop, provide a kind of gas-liquid disturbance obviously to improve the multilayer heterogenic baffling ring high-speed centrifugal rectifying tower that mass-transfer efficiency enlarges markedly.The present invention is achieved through the following technical solutions:
A kind of multilayer heterogenic baffling ring high-speed centrifugal rectifying tower comprises the moving equipment of being made up of machine shaft that runs through housing and multilayer brake puck, the static equipment that multilayer fixed disc and shell are formed, and demarcation strip is imported and exported mutually with relevant gas-liquid.Gas vent and liquid inlet are positioned at the top of housing, and housing bottom has gas access and liquid outlet.In enclosure interior, by bolted multilayer fixed disc housing is divided into multilayer, it is indoor that the mixed gas-liquid flow between layer and the layer mainly occurs in the liquid distribution that is positioned at the fixed disc middle part.Every layer by disk be divided into shell side and centrifugal separating area.At the housing center, the fixed disc and the brake puck that have heterogenic baffling ring in each layer alternately are connected in series on the machine shaft, the corresponding brake puck of one of them fixed disc, fixed disc is on pairing brake puck, and machine shaft is fixedlyed connected with brake puck, fixed disc respectively; Be respectively arranged with fixed disc heterogenic baffling ring and brake puck heterogenic baffling ring on the relative face between fixed disc and the pairing brake puck, brake puck heterogenic baffling ring and fixed disc heterogenic baffling ring are staggered, are fixed on the multilayer fixed disc that is tightly connected with demarcation strip.
When machine shaft rotated, the multilayer brake puck of connection rotated thereupon, and it is static that the multilayer fixed disc keeps, and produces low-pressure area at liquid distribution chamber, simultaneously adjacent brake puck baffling circle and fixed disc baffling cast zig zag circulation passage.Enter the liquid of housing center liquid distribution chamber owing to be subjected to the influence of centrifugal force, between different baffling circles, be zig-zag type and outwards throw away; Because there is low-pressure area in liquid distribution chamber, entering in a zigzag, the gas of passage enters the central area along the liquid flow direction reverse flow simultaneously.
Under the gravity effect, enter down bed device from the isolated liquid in a certain leafing heart Disengagement zone, be enriched in the liquid distribution chamber at center, lower floor Disengagement zone, proceed distillation operation along the inclined surface of lower floor's fixed disc.Gas rises to the outer shell of upper strata centrifugal separating area, and then enters the upper strata centrifugal separating area and carry out the gas-liquid contact.
It is special-shaped that baffling circle on the disk is, and heterogenic baffling ring includes but not limited to that two-dimentional fin hangs down floor, three-dimension fin petal plate, band frid, twill frid, convergent-divergent plate and corrugated plating.
Keep adjacent brake puck baffling circle and the interval volume between the fixed disc baffling circle to equate.
For the ease of intermediate feed, on the second layer and following fixed disc, also be connected with the liquid intermediate feed and take over.The present invention compared with prior art has following beneficial effect:
1, the machine shaft of centrifugal rectifying tower once drives the multilayer centrifugal separating device, and the baffling circle of each layer is radially separated each layer inside again, becomes the rectifiying plate in the layer, and the high distillation process effect of number of theoretical plate is remarkable for improving.
2, the baffling circle adopts abnormally-structuredly, increases the disturbance that can obviously increase the gas-liquid phase after the fluid resistance on a small quantity, significantly improves the mass-transfer efficiency between gas and liquid.
3, the abnormally-structured shaping that can destroy liquid of baffling circle is quickened liquid and is formed drop, improves mass-transfer efficiency.
4, the design that equates of the interval volume between adjacent baffling circle makes number of theoretical plate unanimity that each is corresponding at interval, is convenient to calculate the number of theoretical plate of full tower, is beneficial to design.
5, device structure is simple, and size is convenient to make processing, and stable, operating flexibility is big.
6, multilayer heterogenic baffling ring high-speed centrifugal rectifying tower separative efficiency of the present invention can improve mass-transfer efficiency more than 15%.
