Abstract
In the utility model, an air scavenging loop which connects two adsorption towers and comprises an electromagnetic valve is arranged between the two adsorption towers of a present ordinary double-tower pressure variable adsorption oxygen producing device. Part of oxygen produced in one adsorption tower is utilized to scavenge nitrogen regenerated and released in other adsorption tower into the atmosphere, so that the oxygen concentration in the whole oxygen producing process is increased.
Description
The utility model is about gas separation equipment, particularly about the gas separation equipment with molecular sieve adsorption.
The oxygen that exists in the atmosphere is not only human and one of key element that various biologies are depended on for existence, also is a kind of important industrial raw materials.How oxygen is separated from air, be still an important topic of system gas industry.Industrial oxygenerating mainly is the technical process of adopting low-temperature evaporation for a long time, and it utilizes all gases to have the characteristic of different boiling, produces oxygen, nitrogen and other gas.The technical process that this low-temperature evaporation reaches needs huge equipment, investment is high, current consumption is big, but has advantages such as output is big, purity is high, the big product category of pressure is many, so be applicable to special large scale industry gas delivery factory.Recently development has a kind of selection characterization of adsorption system oxygen of molecular sieve or transformation absorption producing gas method of nitrogen of utilizing again.Make oxygen generating plant in this way have two adsorption tower and gas holders that are full of zeolite molecular sieve usually.Cleaning and exsiccant pressurized air enter in the adsorption tower in turn via the keying of magnetic valve.When adsorption tower of pressurized air inflow carried out nitrogen adsorption, output oxygen, another adsorption tower then made zeolite molecular sieve that adsorbed nitrogen is discharged by reducing pressure, is discharged in the atmosphere and goes, and finishes the regeneration of zeolite molecular sieve.Gas holder is then in order to relax the pulse output of oxygen.This oxygen generating plant is adapted at production scenes such as medical treatment, fishing ground, sewage disposal, chemical pharmaceutical, jewelry manufacturing oxygen is provided continuously, has to reduce expense and the danger of using hyperbaric oxygen and gas cylinder, and instantaneous safety provides the advantage of low-cost oxygen.But because adsorption tower is when regeneration ending, be full of nitrogen in the space in the tower and can't have drained into atmosphere, therefore in next round-robin oxygen preparation, these nitrogen must be exported with oxygen, thereby reduced the oxygen concentration of output, generally between 85%～90%, influenced its application at some production field.
The purpose of this utility model is to provide a kind of double tower THE PRESSURE SWING ADSORPTION OXYGEN GENERATING DEVICE, and it can overcome above-mentioned defective, reaches more than 90% with the oxygen concentration that improves its output.
The purpose of this utility model is achieved in that a kind of double tower THE PRESSURE SWING ADSORPTION OXYGEN GENERATING DEVICE, comprise a pair of adsorption tower of zeolite molecular sieve, admission passage, nitrogen discharge pipeline, oxygen output tube road and the gas holder of being filled with, it is characterized in that being provided with the scavenging loop that comprises magnetic valve that connects described a pair of adsorption tower with magnetic valve with magnetic valve.
Above-mentioned double tower THE PRESSURE SWING ADSORPTION OXYGEN GENERATING DEVICE is characterized in that: be provided with lead and be electrically connected and control the sequence controller that they regularly open and close with magnetic valve in above-mentioned admission passage, nitrogen discharge pipeline and the scavenging loop.
The utility model is compared with existing double tower adsorption oxygen-preparation equipment, only increased a scavenging loop of carrying out regularly to open and close by magnetic valve, be implemented in adsorption tower denitrogen regenerated latter stage, introduce the part of oxygen of another adsorption tower output and drive the interior nitrogen of tower, it is drained, thereby improved entire equipment output concentration of oxygen greatly, can reach 95%～98%.As seen the utility model is simple in structure, and is easily manufactured, with low cost, but can improve the output concentration of oxygen, enlarged its use field and scope.
Below in conjunction with accompanying drawing the utility model is further described.
