Abstract
The utility model relates to a rectifying device which makes use of the tanked liquid oxygen to produce the high-pure oxygen. The upper-part of the liquid-oxygen tank is communicated with the upper-end of a condensing-evaporator arranged in the high-pure oxygen rectifying tower through pipelines and valves. The condensing-evaporator is arranged on the lower-section of the rectifying tower and a high-pure oxygen discharge-pipe is arranged between the condensing-evaporator and the inner-wall of the rectifying tower, and the high-pure oxygen discharge-pipe in a sealed condition is extended out of the rectifying tower and is connected with a liquid-oxygen pump and a high-pressure carburetor. The lower end of the condensing-evaporator is communicated through pipelines and valves with the upper end of a filling tower arranged on the upper-section of the rectifying tower. The upper-end of the filling tower is communicated through pipelines and valves with the lower section of the liquid-oxygen tank, and is communicated with an oxygen compressor through a low-pressure carburetor. The utility model can not only meet the purity requirement to liquid oxygen, without impurity and tiny-dust, but also has no power-cost, with a low-cost.
Description
(1), technical field
The utility model relates to a kind of storage tank liquid oxygen production high purity oxygen rectifier unit that utilizes.
(2), background technology
At present, high purity oxygen is meant a kind of special gas of purity 〉=99.99%, and it is different from common pure oxygen (purity is generally 99.5%), and its price is 20 ~ 150 times of common bottle oxugen, is mainly used in special dimensions such as chemical industry, electronics and analysis.Generally produce, but all have the processing cost height, contain other impurity and micronic dust except that argon gas by cryogenic separation, transformation absorption or other chemical method.Recent years, along with the continuous operation of Large Air Separation Devices, liquid oxygen fills by the storage tank accumulating and becomes more and more general, and liquid oxygen to fill generally be to bathe the formula vaporizer by sky to flash to gas at normal temperature, a large amount of colds can't reclaim.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of storage tank liquid oxygen production high purity oxygen rectifier unit, and it not only can satisfy the purity requirement of liquid oxygen, free from foreign meter and micronic dust, and non-power consumption, and cost is low.
The technical scheme in the invention for solving the technical problem is: pipeline is passed through on the top of liquid oxygen vessel, condenser/evaporator upper end in valve and the high purity oxygen rectifying column is communicated with, condenser/evaporator is in the bottom of high purity oxygen rectifying column, between condenser/evaporator and the high purity oxygen rectifying column inwall high purity oxygen discharge pipe is arranged, the high purity oxygen rectifying column is stretched out in the sealing of high purity oxygen discharge pipe, connect liquid oxygen pump and high-pressure carburetor, pipeline is passed through in the lower end of condenser/evaporator, valve is communicated with the upper end of the packed tower of high purity oxygen rectifier, and pipeline is passed through in the upper end of packed tower, valve is communicated with the bottom of described liquid oxygen vessel and is communicated with oxygen compressor by low pressure carburetor.
The utility model has following advantage: 1, owing to made full use of the cold potential of storage tank liquid oxygen self, high-purity rectification by band hydraulic fluid oxygen, so adopt present technique can realize unpoweredly producing high-quality high purity oxygen, and can not contain other method and produce high purity oxygen institute inevitably small amount of impurities and micronic dust.Simultaneously, emptying gas oxygen purity only slightly reduces, and still can fill bottle and sell; 2, rectifying column adopts structured packing tower element, and the tower resistance is little, and rectifying is abundant; 3, condenser/evaporator adopts the antipriming pipe structure in the rectifying column, and heat exchange efficiency height and heat transfer temperature difference are little; 4, high purity oxygen adopts the plunger-type cryogenic liquid pump pressurized gasification to fill bottle, guarantees to make high-purity oxygen purity without any reduction.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model schematic diagram.
(5), the specific embodiment
As shown in drawings, the top of liquid oxygen vessel 6 is communicated with by interior condenser/evaporator 3 upper ends of pipeline, valve 9 and high purity oxygen rectifying column.Condenser/evaporator 3 has the high purity oxygen discharge pipe in the bottom of high purity oxygen rectifying column between condenser/evaporator 3 and the high purity oxygen rectifying column inwall, and the high purity oxygen rectifying column is stretched out in the sealing of high purity oxygen discharge pipe, connects liquid oxygen pump 7 and high-pressure carburetor 4.The lower end of condenser/evaporator 3 is communicated with the upper end of the packed tower 2 of high purity oxygen rectifier by pipeline, valve 10, and the upper end of packed tower 2 is communicated with the bottom of described liquid oxygen vessel 6 by pipeline, valve 7 and is communicated with oxygen compressor by low pressure carburetor 1.In order to control the work of high purity oxygen rectifying column, on the pipeline between valve 9 and the high purity oxygen rectifying column 6, be communicated with the bottom of liquid oxygen vessel 6 by pipeline, valve 8, heater.
During work, (0.2 ~ 0.7MPa) is directly inputted in the high-purity distillation tower to utilize the liquid oxygen that has pressure in the liquid oxygen vessel 6, implement further high-purity cryogenic rectification, in the condenser/evaporator 3 of tower bottom, obtain the high-purity liquid oxygen, be pressurized to 15MPa with liquid oxygen pump 5 and can fill bottle.Because the PR of high purity oxygen is lower, its purity just is purified to 99.99% from 99.6%, so, the oxygen purity of discharging from essence stream top of tower slightly reduces, also can remain on about 99.5%, meet the regulation of GB, after re-heat, still can fill bottle and sell with the oxygen compressor compression.Condenser/evaporator 3 evaporation and heat-exchanges in the high-purity distillation tower utilize the phase oxygen input circulation of calming the anger of the band of storage tank internal upper part to get final product, do not need other Extra Supply gas converting heat, and the band of the input phase oxygen of calming the anger after becoming liquid, utilizes pressure differential to be pressed into rectifier by valve 10 to participate in rectifying in condenser/evaporator cooling.
