Abstract

The utility model discloses a high purity carbon dioxide extracting device, which is realized by the following steps: adding CO2 in a catalytic combustor to deeply remove the organic impurities therein by a catalytic combustion method; then using adsorption drying to remove water and the like in CO2; and finally liquefying CO2 and using a rectifying tower to remove gases with low boiling point, such as O2, N2 and the like, so as to obtain high-purity liquid CO2 with the purity up to over 99.9995 percent. The carbon dioxide extracting device can be widely applied to the sections of semiconductor, microelectronics, laser, biology, pharmacy, supercritical extraction and the like which need high-purity CO2.

Description

The high-purity carbon dioxide extraction element
Technical field
The utility model relates to a kind of gas purification apparatus, relates to the device that a kind of high-purity carbon dioxide extracts especially.
Background technology
Traditional CO 2Purification devices is at CO 2Middle different impurities adopts the sorbent material of different ingredients and performance to remove various impurity respectively.
The methyl alcohol sorbent material is for example arranged, take off that benzene sorbent material and ethene adsorbent etc. are commercially available and have ten surplus the special-purpose sorbent material of kind.But make CO 2Purity reaches more than 99.9995%, and organic impurity only depends on absorption often to be difficult to eliminate.Food-class CO particularly 2Standard GB 10621-2006 in the content of regulation benzene need be strict controlled in below the 20ppb, adopt absorption method to be not easy to guarantee.
In recent years, in the production process of semiconductor integrated circuit, photoelectric device, adopt supercritical CO 2As clean-out system alternative 18M Ω ultrapure water and high-purity N F are arranged greatly 3The trend of ultrasonic cleaning process, it is to CO 2Purity requirement is also higher.
As seen, along with development of science and technology, CO 2Purposes increasingly extensive, demand constantly increases, to CO 2The requirement of purity is also improving.
Summary of the invention
The utility model is in order to overcome above shortcoming, improves a kind ofly can effectively remove organic high-purity carbon dioxide extraction element.
The technical solution of the utility model is: stock liquid CO 2Storage tank inserts vaporizer, be connected with adsorption dehumifier, liquefier, distillation tower, condenser and product storage tank behind the vaporizer, liquefier is connected to refrigerator, also is connected to heat exchanger, catalytic burner and water cooler between wherein said vaporizer and the adsorption dehumifier successively.
Nanometer palladium platinum catalyst is housed in the described catalytic burner.
The utility model can the degree of depth be removed CO by being provided with catalytic burner by Production by Catalytic Combustion Process 2Middle organic impurities, and the nanometer palladium platinum catalyst that is equipped with in the catalytic burner can need not regeneration by life-time service.
Description of drawings
Fig. 1 is the structural representation of present embodiment;
1. raw material storage tanks wherein, 2. vaporizer, 3. heat exchanger, 4. catalytic burner, 5. watercooler, 6. adsorption dehumifier, 7. refrigerator, 8. liquefier, 9. rectifying tower, 10. condenser, 11. product storage tanks.
Embodiment
Present embodiment utilize Magnesium Chloride Anhydrous easily and ammonia generation chemisorption generate the characteristics of its ammonia complex, proposed the employing Magnesium Chloride Anhydrous and improved purification devices as sorbent material.
As shown in Figure 1, CO 2Raw material storage tank 1 inserts vaporizer 2, gas after vaporizer 2 vaporizations inserts heat exchanger 3, heat exchanger is connected with catalytic burner 4, be provided with internal heater in the catalytic burner 4 and nanometer palladium platinum catalyst is housed, catalytic burner inserts watercooler 5, gas enters adsorption dehumifier 6 after cooling, two parallel connections of adsorption dehumifier 6 usefulness, a job, a regeneration, can hocket work and regeneration guarantee long-term non-stop run, contain adsorption desiccant in it, can purge with the rectifying tower top exhaust gas discharged when normal temperature is regenerated during work.Gas inserts liquefier 8 after adsorption dry, the liquefier cold is provided by refrigeration agent 7, and gas enters rectifying tower 9 after liquefaction, and rectifying tower top is provided with condenser 10, access product storage tank 11 at the bottom of the rectifying tower.
Emphasis of the present utility model is adding catalytic burner, uses the Production by Catalytic Combustion Process degree of depth to remove CO 2Middle organic impurities.Its main chemical reactions is as follows:
CH 4+2O 2→CO 2+2H 2O
C 2H 4+3O 2→2CO 2+2H 2O
2CH 3OH+3O 2→2CO 2+4H 2O
2C 6H 6+15O 2→12CO 2+6H 2O
As seen at CO 2In must contain the oxygen amount that makes the organism complete reaction required of being enough to, a kind of situation is industrial CO 2In itself contain certain oxygen amount, another kind of situation is must be to CO 2In replenish certain oxygen amount.
Product storage tank 11 adopts double-layer vacuum low temperature storage tank, volume 10m 3, CO behind the utility model device purifying 2Purity 〉=99.9995%, wherein O 2＜1ppm, N 2＜1ppm, CH 4＜1ppm, H 2O＜3ppm.

Claims (2)

1. high-purity carbon dioxide extraction element, stock liquid CO 2Storage tank inserts vaporizer, be connected with adsorption dehumifier, liquefier, distillation tower, condenser and product storage tank behind the vaporizer, liquefier is connected to refrigerator, it is characterized in that also being connected to successively between described vaporizer and the adsorption dehumifier heat exchanger, catalytic burner and water cooler.
