Description

Technical Field

[0001] The utility model relates to the technical field of oxygen concentrators, in particular to an ultra-low dew point oxygen concentrator. Background Art

[0002] An oxygen concentrator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the various components in the air are used to separate the gas and liquid at a certain temperature. Then, it is distilled to separate it into oxygen and nitrogen. In general, since it is mostly used to produce oxygen, people are accustomed to calling it an oxygen concentrator. Since oxygen and nitrogen have a wide range of uses, oxygen concentrators are also widely used in the national economy, especially in metallurgy, chemical industry, petroleum, national defense and other industries.

[0003] Existing oxygen production equipment requires a cooler to remove excess moisture from the incoming gas to ensure the service life of the molecular sieve. At the same time, the exhaust gas discharged from the muffler outlet of the ultra-low dew point oxygen concentrator has a very low atmospheric dew point, which will affect the working environment when discharged to the outside. Therefore, we proposed an ultra-low dew point oxygen concentrator that can use the exhaust gas to dehumidify the incoming air, eliminating the traditional cooler and reducing costs. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0024] An ultra-low dew point oxygen concentrator provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0025] Combine Figure 1-3 As shown, the present invention provides an ultra-low dew point oxygen concentrator, comprising: a body component 100 and a cooling component 200 disposed on the body component 100;

[0026] The cooling assembly 200 includes a cooling mechanism arranged in the body assembly 100 and a drainage mechanism installed in the cooling mechanism and connected to the bottom of the cooling mechanism; the cooling mechanism includes a cooling outer box 210 installed in the body assembly 100, a cooling inner box 220 fixed in the cooling outer box 210, an air intake cooling pipe 230 connected to the bottom of the cooling outer box 210, a waste box 240 connected to the end of the air intake cooling pipe 230, a condensation plate 250 arranged on the inner side of the cooling inner box 220, guide grooves 260 opened on both sides of the condensation plate 250, air holes 270 arranged on the condensation plate 250, a cooling plate 250 connected to the cooling outer box 210 and penetrating the air intake cooling pipe 230, and a cooling plate 250 provided on the inner side of the cooling inner box 220. The exhaust pipe 280 and the air inlet 290 and the air outlet 291 connected to the cooling inner box 220 can discharge the low dew point exhaust gas generated by the body component 100 into the waste box 240 through the cooling component 200, and then be introduced into the space between the cooling outer box 210 and the cooling inner box 220 by the air intake cooling pipe 230. At the same time, when the body component 100 is working, the outside air enters through the air inlet 290, and is affected by the low temperature when passing through the condensation plate 250. The moisture in the air will condense on the condensation plate 250, and then the dehumidified air is discharged from the air outlet 291 to the body component 100 for oxygen production. In this way, the air is dehumidified by the exhaust gas of the oxygen generator, eliminating the use of traditional coolers, greatly reducing costs, and facilitating promotion and use.

[0027] Furthermore, the drainage mechanism includes a drainage plate 310 fixed to the lower part of the cooling outer box 210, a liquid inlet hole 320 opened on the drainage plate 310, a liquid collecting box 330 fixed on the drainage plate 310 and located above the liquid inlet hole 320, a through-hole 340 opened on the liquid collecting box 330 for the bottom of the air hole 270 to pass through, a drainage pipe 350 connected between the outer end of the drainage plate 310 and the waste box 240, and a control valve 360 ​​arranged on the drainage pipe 350. Through the drainage mechanism, the condensed water generated on the condensation plate 250 can enter the liquid collecting box 330 along the guide groove 260, and then pass through the liquid inlet hole 320 into the drainage plate 310, and then flow from the drainage pipe 350 to the waste box 240 for storage, thereby realizing the automatic collection of condensed water and requiring regular cleaning.

[0028] Specifically, a cooling channel is provided between the cooling outer box 210 and the cooling inner box 220, and the condensation plate 250 is connected to the cooling channel, so that the low dew point exhaust gas generated by the body assembly 100 can enter the cooling channel and be filled in the condensation plate 250 to increase the contact area with the flowing air, thereby improving the condensation effect.

[0029] Furthermore, the condensation plates 250 are conical plate structures evenly arranged in the cooling inner box 220. The conical plate structure facilitates the condensed water to flow into the liquid collecting box 330 and then enter the liquid drain plate 310 for discharge, which is more reasonable.

[0030] On the other hand, the air holes 270 are staggeredly distributed on the condensation plate 250, which can make the incoming air flow in an S shape, increase the flow time of the air in the cooling inner box 220, and ensure the condensation effect.

[0031] Furthermore, the guide groove 260 is a concave triangular groove structure, which can allow the condensed water to flow into the liquid collecting box 330. At the same time, the incoming air will not carry the water in the liquid collecting box 330 to flow to the next step, thereby better controlling the condensed water.

[0032] The working principle and usage process of the present invention are as follows: first, the low dew point exhaust gas generated by the body assembly 100 is discharged into the waste box 240, and then introduced into the space between the cooling outer box 210 and the cooling inner box 220 through the air intake cooling pipe 230. At the same time, when the body assembly 100 is working, the outside air enters through the air inlet 290, and is affected by the low temperature when passing through the condensation plate 250. The moisture in the air will condense on the condensation plate 250, and then the dehumidified air is discharged from the air outlet 291 to the body assembly 100 for oxygen production, and the exhaust gas between the cooling outer box 210 and the cooling inner box 220 is discharged from the exhaust pipe 280. In this way, the exhaust gas of the oxygen generator is used to dehumidify the air. At the same time, the condensed water generated on the condensation plate 250 enters the liquid collection box 330 along the guide groove 260, and then passes through the liquid inlet hole 320 into the drain plate 310, and then flows from the drain pipe 350 to the waste box 240 for storage, and the condensed water can be automatically collected.

[0033] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
