Abstract
The utility model relates to a purifier of fine chemicals. The utility model is especially suitable for the purifying separation of organic solvent in the class of comprising amino group. The utility model has the technical proposals that the utility model comprises a pressure reducing distillation kettle, an infusion pump, an air pump, pipe lines and a control valve, wherein the pressure reducing distillation kettle is a closed structure, the pipe line of the air pump which enters from the bottom of the pressure reducing distillation kettle is connected with a gas nozzle and the pipe line of the infusion pump which enters from the upper part of the pressure reducing distillation kettle is connected with a liquid nozzle. The upper part of the pressure reducing distillation kettle is also provided with a gas outlet pipe line after reaction, and the outlet pipe line is connected with a vacuum pump. The pipe line of the air pump is also provided with a gas drying tank and a gas heater. The outlet pipe line is also provided with a heat exchanger and a product collector. The utility model has the advantages of enhancing product purification rate, shortening purification time and reducing cost and energy consumption.
Description
One, technical field: the utility model relates to a kind of purification device of fine chemical product, and the purification that is specially adapted to contain the organic solvent of amino class separates.
Two, background technology: the present purifying plant that uses, the device that especially adopts gas phase, liquid phase hybrid separation to purify mainly comprise decompression distillation still, infusion pump, air pump and pipeline and control valve composition.The liquids and gases that enter the decompression distillation still the decompression distillation still can not fully mix or incorporation time longer, cause defectives such as the reduction of product purification rate, purification time length, cost height easily.
Three, summary of the invention: the purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of purification device of fine chemical product of quick purification is provided.
Its technical scheme is: comprise decompression distillation still, infusion pump, air pump and pipeline and control valve composition, wherein the decompression distillation still is an enclosed construction, and the pipeline of air pump enters from the bottom of decompression distillation still, and is connected with gas nozzle; The pipeline of infusion pump enters from the top of decompression distillation still, and is connected with fluid injector; Also be provided with reaction back outlet gas line on the top of decompression distillation still, outlet line is connected with vavuum pump.On the pipeline of air pump, also be provided with gas drying chamber and gas heater, on outlet line, also be provided with heat exchanger, product gatherer.
Effect of the present utility model is: the product purification rate improves greatly, the shortening greatly of purification time, cost and energy consumption reduce.
Four, description of drawings:
Accompanying drawing is a structure diagram of the present utility model.
Five, the specific embodiment:
1 is the reactant liquor that needs purification among the figure; The 2nd, the decompression distillation still is stainless steel or enamel material, mechanism's sealing; The 3rd, heat exchanger, stainless steel material, coiled; The 4th, air pump; The 5th, product gatherer, stainless steel material, taper back cover, closed container; The 6th, the built-in fluid injector of decompression distillation still; The 7th, the built-in heated drying air nozzle of decompression distillation still; The 8th, vavuum pump; The 9th, gas drying chamber, stainless cylinder of steel, interior dress φ 3mm active carbon; 10, the admission line of band heating tape; 11, heated drying air air intake control valve door.
To react gained reactant liquor (for example methyl carbamate) 1 by infusion pump, gate valve, pipeline, disperse to enter decompression distillation still 2 with the sprinkling form through special fluid injector 6.After the admission line of air by gas drying chamber 9, air pump 4, heated drying air air intake control valve door 11, band heating tape entered from decompression distillation still 2 bottoms, heated drying air nozzle and fluid injector 6 relative sprinklings fully mixed gas-liquid.Mixed gas makes by vavuum pump 8 and forms low-pressure states in the decompression distillation still 2, need the reactant liquor of purifying to enter the heat exchanger cooling with the pipeline of giving vent to anger of gaseous state by decompression distillation still 2 tops after, enter product recover 5.So obtaining the methyl carbamate rate of recovery is 96%, and methyl carbamate content is more than 99.5%.
Use measures such as the temperature of this device by control reactant liquor, gas, heat exchanger and decompression distillation still, pressure, can satisfy the purification requirement of different product.
Claims (2)
1, a kind of purification device of fine chemical product, comprise decompression distillation still, infusion pump, air pump and pipeline and control valve composition, it is characterized in that: the decompression distillation still is an enclosed construction, and the pipeline of air pump enters from the bottom of decompression distillation still, and is connected with gas nozzle; The pipeline of infusion pump enters from the top of decompression distillation still, and is connected with fluid injector; Also be provided with reaction back outlet gas line on the top of decompression distillation still, outlet line is connected with vavuum pump.
2, purification device of fine chemical product according to claim 1 is characterized in that: also be provided with gas drying chamber and gas heater on the pipeline of air pump, also be provided with heat exchanger, product gatherer on outlet line.
