[technical field]
The present invention relates to a kind of condensation of gas device, specifically a kind of gas classification device and application process.
[background technology]
Gas is a kind of existence form of material, in daily life and industrial production, all can produce a lot of gas.Containing granule phase substance in air, moisture, carbon monoxide, oxynitrides etc., Chemical Manufacture emission gases contains a lot of volatility and half volatile composition, and some of them composition can damage human body, therefore for the process of gas, receive the very large concern of international community all the time.In industrial production, a lot of product is volatility and half volatile material, by gas classification condensation therefrom being extracted required beneficial or removing harmful substance, has become the Main way of current gas studies.
Current conventional gas classification condensation method mainly contains following several:
(1) water-bath fractional condensaion method: refer to that gas carries out exchange heat by low temperature water-bath, reach reduction gas temperature, make the method for components condense.General serviceability temperature is at about 4 DEG C.The method serviceability temperature narrow range, condensation effect is general, and grading effect is not good, and is applicable to high-temperature gas more.
(2) air classification condensation method: when referring to gas by air set pipe, high-temperature gas and extraneous Cryogenic air heat exchange, temperature reduces, and makes the method for components condense in gas.The method is applicable to high-temperature gas, and fractional condensaion effect is not as water-bath condensation method.
(3) cold-trap fractional condensaion method, refers on the surface of cooling with the method for mode captured gas of condensing.Advantage to accomplish any ultralow temperature condensation, but shortcoming to provide a kind of stable temperature.
Although the above gas classification condensation method has certain condensation effect to gas, grading effect extreme difference, after therefore many gas components are condensed, need to be separated by the further classification of other chemical methodes.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, a kind of gas classification device and application process are provided; During application, ultralow temperature gas is passed into condensation transfer tube, and make device stablize formation temperature gradient; Then the temperature end of gas to be fractionated from device inputted, different component is condensed in different collecting pipes according to the difference of its boiling point, and can be discharged by pipe valve, collects.
The object of the invention is to be achieved through the following technical solutions:
A kind of gas classification device, comprises low-temperature receiver, the collecting pipe of parallel arrangement, heat-insulation layer, low-temperature receiver transfer tube, pipe valve, heat transfer clamping plate, temperature detector; Low-temperature receiver connects low-temperature receiver transfer tube, and collecting pipe is connected by pipe valve and the thermocouple probe of temperature detector is together parallel is placed between heat transfer clamping plate; Heat-insulation layer is wrapped in low-temperature receiver transfer tube and heat transfer clamping plate.
The number of described collecting pipe is two or more.
