Abstract
The utility model discloses an oxygen and oxygen-enriched air preparation device, which comprises an air compressor, a cooling and drying machine, a dewatering oil filter and nitrogen and oxygen separation equipment. An outlet of the air compressor is connected with an inlet of the cooling and drying machine, an outlet of the cooling and drying machine is connected with an inlet of the dewatering oil filter, an outlet of the dewatering oil filter is respectively provided with a first pipe and a second pipe, the first pipe is connected with an inlet of the nitrogen and oxygen separation equipment, and the second pipe is successively provided with a pressure control valve, a flow limiting stop valve and a pneumatic adjusting valve, then is connected with an oxygen outlet of the nitrogen and oxygen separation equipment and is connected with an inlet of a gas storage tank via a sensor. The oxygen and oxygen-enriched air preparation device has the advantages that the oxygen and oxygen-enriched air preparation device is simple in principle and low in production cost and can effectively control oxygen purity, so that the stable oxygen purity is obtained, and simultaneously, suitable oxygen concentration can be selected according to different work conditions.
Description
Technical field
The utility model relates to a kind of oxygen and oxygen enrichment device for making, particularly a kind of oxygen and oxygen enrichment device for making.
Background technology
The control characteristic of common breathing equipment is on the existing market: molecular sieve oxygen generation equipment is by air pressurized air usually, is connected on the air cushioning gas-holder, through the air that buffering dewaters, is exported by gas-holder top.Get into the strainer dedusting and dewater, be connected to cooling driers, connect T level strainer and A level strainer then.Get into oxygen, nitrogen separation equipment, the oxygen of separating connects the product gas surge tank, measures at last and analyzes.The oxygen purity and the flow of conventional oxygenerator are inversely proportional to, and promptly downtrending appears in oxygen purity when flow increases, and cause oxygen purity unstable.
Summary of the invention
To the shortcoming of existing oxygen generating plant, the utility model provides a kind of novel oxygen and oxygen enrichment device for making.
To achieve these goals, the measure taked of the utility model:
A kind of oxygen and oxygen enrichment device for making comprise air, cooling driers, the oil strainer that dewaters, nitrogen oxygen separation device, and the air outlet is connected with the cooling driers inlet, and the cooling driers outlet enters the mouth with the oil strainer that dewaters and is connected; The oil strainer that dewaters outlet is respectively arranged with first pipeline, second pipeline; First pipeline is connected with the import of nitrogen oxygen separation device, sets gradually pressure control valve, current limliting stopping valve, pneumatic adjusting valve on second pipeline and is connected with the oxygen outlet of nitrogen oxygen separation device behind the door and is connected with the gas-holder import through transmitter; Simultaneously, transmitter is connected with the quantitative analysis annex, and meanwhile, the quantitative analysis annex is connected with the pneumatic adjusting valve door through unit; The nitrogen oxygen separation device is provided with the air output equipment.
The beneficial effect of the utility model: principle is simple, and production cost is low; Can effectively control oxygen purity and obtain stable oxygen purity, simultaneously, can select suitable oxygen concentration according to the difference of operating mode.

Embodiment
A kind of oxygen and oxygen enrichment device for making; As shown in Figure 1; Comprise air 1, cooling driers 2, the oil strainer 3 that dewaters, nitrogen oxygen separation device 4, air 1 outlet is connected with cooling driers 2 inlets, cooling driers 2 outlets enter the mouth with the oil strainer 3 that dewaters and are connected; Oil strainer 3 outlets that dewater are respectively arranged with first pipeline, second pipeline; First pipeline is connected with 4 imports of nitrogen oxygen separation device, sets gradually pressure control valve 6, current limliting stopping valve 7, pneumatic adjusting valve door 8 on second pipeline and afterwards is connected and is connected with gas-holder 11 imports through transmitter 9 with 4 outlets of nitrogen oxygen separation device; Simultaneously, transmitter 9 is connected with quantitative analysis annex 10, and meanwhile, quantitative analysis annex 10 is connected with pneumatic adjusting valve door 8 through unit 12; Nitrogen oxygen separation device 4 is provided with air output equipment 5.In the actual implementation process of patent, air gets into cooling driers 2 behind air 1, handles the back through cooling driers 2 and gets into the oil strainer 3 that dewaters; Behind the oil strainer 3 that dewaters, output terminal is divided into two pipelines, and the air admission nitrogen oxygen separation device 4 of first pipeline is carried out nitrogen oxygen separating treatment; The air of first pipeline is after separating, and air is through equipment 5 outputs, and isolated oxygen mixes with the air of second pipeline, gets into gas-holder 11 through transmitter 9 after the mixing; The purity of the interior oxygen of 9 pairs of gas-holder of transmitter detects and carries out concentration analysis through quantitative analysis annex 10 in real time; After the analysis oxygen purity signal is introduced unit 12; Unit 12 compares feedback signal and setting data; Result outputs to pneumatic adjusting valve door 8, and control output oxygen purity reaches the purpose of stablizing the oxygen output purity near setting data automatically.Owing to adopted present method, can effectively control oxygen purity near set(ting)value, obtain stable oxygen purity; And the constant product quality that obtains.Can select suitable oxygen concentration according to the difference of operating mode; System adopts automatic regulative mode to follow the tracks of the output purity of regulating oxygen, overcome the shortcoming that oxygen purity is followed fluctuations in discharge; Purity step-down when flow is big, the situation that flow uses hour purity to uprise; Function with a tractor serves several purposes.
Those skilled in the art's simple change and replacement all are within the protection domain of the utility model in this area.
