Description

Nitrogen carbon carries purifier apparatus

Technical field:

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

Background technology:

Traditional nitrogen purification equipment is by nitrogen emptying device, deoxygenator, water cooler, absorption type dryer, dust secondary filter, controller, forms with pipe connection.Because nitrogen and oxygen all are more active gas, so, in producing the process of nitrogen, no matter be to add carbon deoxygenation purifying, or the deoxidization by adding hydrogen purifying, difficulty is separated oxygen from general nitrogen, more difficultly oxygen impurities is eliminated the not high major cause of nitrogen gas purity that Here it is in nitrogen.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.The nitrogen emptying device has comprised oil eliminator, cold dried device, activated charcoal filter, snubber.

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 nitrogen carbon and carries purifier apparatus, and its scheme is: whole by nitrogen emptying device, deoxygenator, water cooler and the absorption type dryer that is being linked in sequence, dust secondary filter, controller, form with pipe connection; On general nitrogen enters the mouth pipeline between deoxygenator, be provided with interchanger, and, in the heat exchange jar, be provided with a pipeline that passes the heat exchange jar, two pipe ends that connected French Franc, be exposed to the outside surface of heat exchange jar respectively,, connect with the French Franc that is connected the cooling tank upper end with the French Franc on the pipe end of an end, with the French Franc on the pipe end of the other end, with the pipe connection in the back threeway that is connected the deoxidation jar; On the pipe end that connects general nitrogen inlet, be provided with threeway, tensimeter is installed in the threeway by pipe connection; In deoxygenator, between the pipeline with the deoxygenator two ends, by inserting threeway, ball valve, pipeline, one group of same and deoxygenator that can take turns mutually or connect and use, set up a branch road separately, and between the preceding threeway of back threeway on deoxygenator and lower end, connected a pipeline, united and be two deoxygenators; Two deoxygenators and preheater follow the pipe end that passes heat exchange jar pipeline to connect with first three universal pipes of two deoxygenators upper end, combine mutually; Two deoxygenators and watercooler follow the French Franc of passing heat exchange jar lower end of duct to connect, pass the French Franc of heat exchange jar pipeline upper end and the French Franc pipe connection of cooling tank upper end with back three general pipelines of two deoxygenators lower end, combine mutually.

Owing to adopted such scheme, by in nitrogen purification equipment/system, deoxygenator is formed two deoxygenators, be provided with a pipeline between the back threeway that preceding threeway of setting up in two deoxygenators upper end and lower end are set up, pipeline behind the deoxygenator is passed preheater, not only, the energy save energy, in preheater, remove a part of impurity, and, can be by actual needs by ball valve being carried out the conversion of Push And Release, realize that two groups of deoxygenators are taken turns or series connection is used, in the deoxidation jar, oxygen impurities fully is converted into carbonic acid gas, cool off through supercooler, along with water in the nitrogen and carbonic acid gas are removed, remove the oxygen impurities in the nitrogen to greatest extent, obtained high-purity nitrogen.This technical scheme, both further perfect nitrogen purification equipment and technical process, further promoted the nitrogen purification technological layer again,, provide technical qualification for producing high-purity nitrogen, satisfying the demand of high-purity nitrogen Application Areas to high-purity nitrogen and nitrogen purification equipment.
