Abstract

Disclosed is an automatic hydrogenation proportioning device. By adding a pressure regulating valve, a flow meter and a pneumatic valve, or utilizing a tee and a ball valve and preparing a hand-operated hydrogen supply branch, the automatic hydrogenation proportioning device can automatically regulate pressure and flow rate of hydrogen, and then automatically provide moderate hydrogen to a deoxygenator on the basis of a relatively reasonable hydrogen and oxygen proportion value according to quantity demand of oxygen on hydrogen metered by the pressure regulating valve and the flow meter, thereby not only achieving purposes of completely removing oxygen impurities in nitrogen to guarantee purification of nitrogen and increase impurity of nitrogen, but also avoiding excessive nitrogen which causes remain of oxygen impurities in nitrogen and insufficient deoxygenization, and being capable of meeting low requirements upon nitrogen purity for users by only using a prepared hand-operated hydrogen supply branch. The technical scheme not only further improves the nitrogen purification device and processing procedures, but also further upgrades technical level of the nitrogen purification technique and provides technical conditions for preparing high-purity nitrogen and meeting requirements of the high-purity nitrogen application filed upon high-purity nitrogen and nitrogen purification devices.

Description

Automatic hydrogenation matching device

Technical field:

The utility model relates to air separation equipment/system, especially produces the equipment of making nitrogen/system of high-purity nitrogen.

Background technology:

Traditional nitrogen purification equipment, be by nitrogen emptying device, interchanger, deoxygenator, water cooler, absorption type dryer, dust secondary filter, controller, form with pipe connection, the nitrogen emptying device has comprised oil eliminator, cold dried device, activated charcoal filter, snubber.Because nitrogen and oxygen all are more active gas, so, in the nitrogen purification process, no matter be to add carbon deoxygenation purifying, still the deoxidization by adding hydrogen purifying is all separated oxygen than difficulty from general nitrogen, more difficult oxygen impurities is eliminated in nitrogen.The not high major cause of nitrogen gas purity that Here it is.So-called " general nitrogen ", what come to this is a kind of because the nitrogen deoxidation not to the utmost also contains the ordinary nitrogen of oxygen impurities.With traditional nitrogen purification equipment, the nitrogen of acquisition, its purity, just slightly high than general nitrogen, but do not reach requirement far away as 99.995% high-purity nitrogen.As nitrogen purification equipment with deoxidization by adding hydrogen, even, hydrogen impurity can in nitrogen, be produced because of hydrogen is excessive.

Along with the progress and development of society at aspects such as science and technology, epoch, as nitrogen Application Areass such as electronics, thermal treatment, food, chemical industry, chemistry, medicine, requirement to nitrogen gas purity is also more and more higher, thereby, become the requirement that must improve the equipment of making nitrogen and technical process.Have only emphatically by the equipment of making nitrogen is transformed, and the improving of corresponding nitrogen producing craft and flow process, could to greatest extent the oxygen impurities in the general nitrogen be removed, make high-purity nitrogen, just can help relevant industries and adapt to social development, could satisfy the demand of relevant industries nitrogen purification equipment and high-purity nitrogen.This is final, a challenge that has become the air separation plant production to face and to set about finishing undoubtedly.

Summary of the invention:

Order of the present utility model provides a kind of automatic hydrogenation matching device, and its objective is such realization: integral body is formed by pipe connection mainly by hydrogen inlet, valve, under meter, hydrogen outlet; On the pipeline of hydrogen inlet front, be provided with a relief valve, and, disconnected the pipeline of under meter back, ball valve front, and between the pipeline that disconnects, be provided with under meter and operated pneumatic valve assembly by pipe connection phase interconnected body, perhaps, again respectively under meter back, pneumavalve front, on two segment pipes of ball valve back, relief valve front, respectively be provided with a threeway, and between two threeways, with the pipe connection ball valve, with by threeway, pipeline, ball valve, pipeline, under meter, pipeline, pneumavalve, pipeline, three-way flow is arranged side by side to automatic hydrogen supply branch road, is provided with one by threeway, pipeline, ball valve, pipeline, three-way flow to manual hydrogen supply branch road.

Owing to adopted such scheme, in nitrogen purification equipment, acquired automatic hydrogenation matching device, just the oxygen that can measure according to relief valve and under meter is to the demand of hydrogen, the pressure and the flow of hydrogen automatically adjust, with relatively reasonable hydrogen-oxygen proportioning, automatically provide appropriate amount of hydrogen to deoxygenator, both reached the oxygen impurities of fully removing in the nitrogen so that guarantee nitrogen purification, improve the purpose of nitrogen gas purity, and reached again and avoided that hydrogen is excessive to cause containing in the nitrogen hydrogen impurity or deoxygenation purpose not to the utmost still; Just the manual hydrogen supply branch road that can have with use satisfies the less demanding user of nitrogen gas purity.This technical scheme, both further perfect nitrogen purification equipment has further promoted the nitrogen purification technological layer again, for producing high-purity nitrogen, satisfying the demand of high-purity nitrogen Application Areas to high-purity nitrogen and nitrogen purification equipment, provides technical qualification.
