Description
technical field:
The utility model relates to a kind of rectifying device of efficient separation and purification organic solvent, particularly be a kind of overcritical highly efficient distilling knockout tower.
background technology:
In chemical process, more and more higher to the purity requirement of organic solvent.Need to process multiple mixed solvent simultaneously.Wherein often meet multiple mixed solvent and azeotropic, separation is a large common technology difficult problem.The separated from solvent conventionally with polynary azeotropic properties, needs by rectifying knockout tower separated rectification and purification step by step repeatedly repeatedly.
Rectifying knockout tower is divided into packed tower and the large type of sieve-plate tower two, its operation principle is all that steam enters at the bottom of by tower, carry out counter current contacting with decline liquid, two contact, and volatile (low boiling) component in decline liquid constantly shifts in steam, difficulty volatilization (higher boiling) component in steam constantly shifts in decline liquid, steam more approaches tower top, and its volatile components concentration is higher, and at the bottom of decline liquid more approaches tower, its difficult volatile component is more enrichment, reaches the object of component separation.Adopt separated solvent in this way, purity is low, efficiency is low, energy resource consumption is large.
utility model content:
The purpose of this utility model is the deficiency of solvent being purified in order to solve material filling type, sieve-board type rectifying column, provides a kind of separation and purification purity polynary to having, vapor of mixture organic solvent high, and efficiency is high, energy-conservation overcritical highly efficient distilling knockout tower.
The purpose of this utility model is achieved like this:
The overcritical highly efficient distilling knockout tower of the utility model is the improvement on the basis of existing rectifying knockout tower, comprise the separated king-post that reboiler, bottom be communicated with reboiler by pipeline, the condenser being communicated with knockout tower column top by pipeline, the sampler being communicated with condenser discharging opening, the cooler being communicated with by extraction pipeline and sampler discharging opening, with the separated solvent tank of cooler discharging opening connection, separated king-post is communicated with sampler by reflux line, it is characterized in that, on reboiler and/or separated king-post, ultrasonic generator is housed.
Ultrasonic generator is equipped with in above-mentioned reboiler outside or inside.
Ultrasonic generator is equipped with respectively in above-mentioned reboiler outside and inside.
Ultrasonic generator is equipped with in above-mentioned separated king-post outside or inside.
Ultrasonic generator is equipped with respectively in above-mentioned separated king-post outside and inside.
Above-mentioned separated king-post is filling-material structure or sieve-plate structure.
In the utility model when work: mixed solvent to be separated is heated to after infinite reflux state in reboiler, reboiler reaches boiling point, is gas-liquid critical condition with the mixed solvent in separated king-post, and in reboiler, gas-liquid evaporation and condensation reach dynamic equilibrium.Open ultrasonic generator input ultrasonic wave, hyperacoustic higher-order of oscillation energy impels the low boiling point solvent molecule acquisition energy under critical condition to evaporate and become gas phase from liquid phase.The inner reception after ultrasonic energy of separated king-post under thermal equilibrium state, low boiling point solvent in separated king-post in the mixed solvent of condensation again obtains energy and is vaporized and is pushed in condenser, is condensed into liquid state, by sampler, cooler, enter separated solvent tank, complete the separation of solvent.
The utility model is polynary to having, the separation and purification purity of vapor of mixture solvent is high, and efficiency is high, energy-conservation.The utility model, in the situation that not increasing tower height, improves the theoretical cam curve of rectifying column to separated from solvent and purification greatly.When improving rectifying column separating power, also compared with conventional rectification tower, save energy consumption 15%-20%.
