Abstract
The utility model relates to an energy-saving double-tower type oxygen-making air separation machine. The energy-saving double-tower type oxygen-making air separation machine comprises a tower A, a tower B, a connection pipeline between the tower A and the tower B, and oxygen collection pipelines, wherein the oxygen collection pipelines are respectively provided with an air collection valve used for collecting qualified oxygen and an air release valve used for discharging unqualified oxygen, the air collection valve is communicated with an air collection device, and the air release valve is respectively connected with the tower A through a blow down valve of the tower A and is communicated with the tower B through a blow down valve of the tower B. According to the energy-saving double-tower type oxygen-making air separation machine, the unqualified oxygen produced in the preliminary working stage of the tower A is utilized to blow the tower B through the line of the air release valve - the blow down valve of the tower B. When the tower B starts to work, the tower A is blown using the similar method.
Description
Technical field
The utility model relates to a kind of air separation machine, especially relates to a kind of double-tower type system oxygen air separation machine.
Background technology
Double-tower type anoxic air separation machine generally is the gas except that oxygen in the molecular sieve filtration air that utilizes in the adsorption tower, two adsorption tower alternations, and an adsorption tower is when work, and an other adsorption tower is being given birth at purging.Adsorption tower need provide gas gas to purge by another adsorption tower at work in the process of giving birth to.
When adsorption tower is just started working, can produce the not high defective oxygen of more a large amount of purity, these defective oxygen generally can only fall as exhaust gas emission, and this causes very big waste.
Summary of the invention
The utility model mainly is to solve a large amount of defective oxygen of existing in prior technology as exhaust gas emission; Cause the technical problem of very big energy dissipation, the double-tower type system oxygen air separation machine that provides a kind of simple in structure, easy to operate, energy-conservation defective oxygen recovery to utilize.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of energy-saving double-tower type system oxygen air separation machine; Comprise A tower, B tower; Connecting pipeline between A, the B tower and oxygen are collected pipeline; It is characterized in that being respectively equipped with one on the described oxygen collection pipeline is used for gas collection valve and blow-off valve that is used to discharge defective oxygen that qualified oxygen is collected; Described gas collection valve is connected with a gas extractor, and described blow-off valve links to each other with described A tower through A tower blow down valve respectively; Be connected with the B tower through B tower blow down valve.When the A tower was started working, the B tower need purge, and the defective oxygen that the utility model utilizes the A tower work initial stage to produce passes through the route of exhaust-valve-B tower blow down valve, and the B tower is purged.Like this with regard to reasonable use defective oxygen, avoided the directly waste that caused of discharging of defective oxygen.When the B tower is started working, also can purge the A tower through above-mentioned similar method.
As preferably; Described oxygen is collected the proofing unit that pipeline is provided with an oxygen purity; The signal of this proofing unit sends end and links to each other with a unit, and the signal output part of this unit links to each other with described gas collection valve, blow-off valve, A tower blow down valve, B tower blow down valve respectively.When proofing unit finds that the purity of oxygen is not enough, promptly control corresponding valve through unit, make defective gas enter into the adsorption tower that carries out regenerative operation, when oxygen purity reaches requirement, be about to gas and introduce in the gas extractor.
As preferably, described oxygen is collected pipeline and is provided with an oxygen surge tank.The oxygen surge tank has shock absorption to the oxygen of producing, and makes that the gas flow of its output is even, helps collecting, purges, detects.
As preferably, be provided with an on-off valve between described A tower and the B tower.When proofing unit records the gas of producing when qualified, oxygen will be collected, and open on-off valve this moment, through the A tower B tower or B tower purged the A tower.
The beneficial effect that brings of the utility model is; The a large amount of defective oxygen of existing in prior technology have been solved as exhaust gas emission; Cause the technical problem of very big energy dissipation, realized the double-tower type system oxygen air separation machine that a kind of simple in structure, easy to operate, energy-conservation defective oxygen recovery is utilized.
