Abstract
The present invention relates to gas liquid conduction equipment-board tower. The board tower consists of several tower burls where lays tower board. The liquid is flowing along the board weir and distributing dentation board by board like a curtain. When the gas and liquid meet and react, it will become adverse current. The tower tray is arc and there are sawtooth upside weir and underside distributing dentation. The tower burl and tower board are made from metal, acid-resistant pottery that are corrode-resistant or package steel corrode-resistant. The present invention can prevent from separating out and jam of the gas and liquid. The equipment can provide conduction value and conduction area. It operates flexibly and resistance value is little.
Description
Affiliated technical field:
The present invention relates to a kind of gas-liquid phase mass transfer apparatus---plate column, can be used for gas-liquid phase reaction or the gas-liquid situation of other contacts mutually, belong to gas-liquid mass transfer (contact) equipment.
Background technology:
About the design of gas-liquid mass transfer (contact) equipment, generally from the process rule, normally good gas-liquid contact provides maximum mass tranfer coefficient and mass transfer area and has big as far as possible adverse current and forms concentration gradient to greatest extent, so that the motive force of actual maximum to be provided.Conventional tower is considered the engineering factor of gas-liquid mass transfer (contact) equipment, by transforming the tower plate structure in the tower body or filler being installed being pursued big as far as possible specific area, promotes gas-liquid mass transfer.For mass transfer apparatus between solution type liquid and the gas, often, may separate out solid in the process because liquid holdup is not enough, blocking portion passage even obstruction make whole tower and can not adapt to.Wang Jianxiang is at China's " chemistry world " nineteen ninety-five the 36th volume the 4th phase 178～180 pages of reports " synthetic simultaneously POCl3 and thionyl chloride new technology ", and this reacts with solute in solution with the new technology of still reaction at intermittence, gas.Wang Jianxiang applies for Chinese invention patent " a kind of continuous method for preparing thionyl chloride and POCl3 " (application number: 031433693) again, relate to tower reactor and finish chemical process, thionyl chloride and POCl3 are produced in chlorine in this method and sulfur dioxide and the reaction of phosphorus trichloride counter current contacting.Because in this technological reaction process, at first phosphorus trichloride and chlorine reaction generate the solid phosphorus pentachloride, the reaction of phosphorus pentachloride and sulfur dioxide generates thionyl chloride and POCl3 then.Initial reaction stage, phosphorus pentachloride is solution state by phosphorus trichloride dissolving, and product thionyl chloride and the POCl3 that generates with the sulfur dioxide reaction serves as solvent again then, then forms the gas-liquid reaction that contacts.And plate column equipment liquid holdup commonly used is often little, also is subjected to the restriction of operating flexibility scope, is easy to generate solid and stops up the requirement that does not reach above-mentioned technology.
Summary of the invention
In order to satisfy the phase reaction of continuous tower solution-type gas-liquid, the invention provides a kind of gas-liquid mass transfer (contact) equipment---plate column that liquid holdup is big, gas-liquid contacts, operating flexibility is big, simple in structure, easy to manufacture, corrosion-resistant again, cost is low, easy to maintenance that has.
The technical solution adopted for the present invention to solve the technical problems is: as shown in Figure 1, plate column is made up of a plurality of tower joints.Leave groove at every Jie Tajie port and be used for the column plate mounting groove, column plate is easy for installation and removal.Column plate is installed between the tower joint, neighbouring column plate arranged crosswise.Liquid is the liquid tentiform downwards along plate weir and distributed tooth step by step tray and flows, and gas is rising with liquid curtain cross-flow bubbling haptoreaction and step by step tray, and full tower forms counter current contacting.
This gas-liquid mass transfer (contact) equipment is used for the gas-liquid contact reaction tower between solution type liquid and the gas, beneficial effect is that the peviform structure on column plate top is controlled energy receiving fluids quantity by weir on the zigzag of setting, guarantee big liquid holdup, can prevent in the gas-liquid contact process, may separate out the clogging that solute produces in the liquid solution; This reaction tower gas carries out on column plate interstitial fluid curtain with contacting mainly of liquid, produces effectively controlled gas-liquid contact, and reliable mass tranfer coefficient and mass transfer area are provided; This tower have gas and liquid the changes in flow rate scope---operating flexibility is big, can not produce owing to gas and fluid flow change to cause the liquid flooding and the phenomenon of leakage, cause the tower body cisco unity malfunction; The gas-liquid contact is bubbling on the liquid curtain only, and the reaction tower SR is little; Tower plate structure is simple, can be in order to directly to make with resisting and acidproof ceramic material to adapt to the characteristics of this series material deep-etching.
The reaction tower that the present invention is used for preparing simultaneously continuously thionyl chloride and POCl3, avoided in the course of reaction phosphorus pentachloride solid to separate out the obstruction tower, this equipment has good relatively gas-liquid contact, the characteristics that the mass tranfer coefficient and the mass transfer area of this arts demand can be provided and adapt to this series material deep-etching.
