Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen production technology, and more specifically, to a highly efficient gas dehydration device for a nitrogen production system. Background Art

[0002] The nitrogen production system refers to a process that uses air as raw material and uses physical methods to separate oxygen and nitrogen in the air to obtain nitrogen. In order to ensure the nitrogen production effect during the current nitrogen production process, the water in the gas needs to be removed by a gas dehydration device when the gas is transported to the nitrogen production system.

[0003] Most of the existing gas dehydration devices generally filter out the moisture in the gas through a dehydration filter element to ensure the dryness of the gas. However, in the process of dehydrating the gas, when the filter element is used for a long time, the water droplets condensed on the surface of the filter element are easy to adhere to the surface of the filter element. At this time, since the mesh of the filter on the filter element is small, the filter mesh is easy to be blocked, resulting in low air dehydration efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a highly efficient gas water removal device for a nitrogen production system which can scrape off water droplets attached to the surface of a water removal filter element, thereby avoiding the problem of excessive water droplets adhering to the surface of the water removal filter element and causing filter pore blockage, and further ensuring the long-term use effect of the water removal filter element.

DETAILED DESCRIPTION

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0022] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually used in reference to the directions shown in the drawings, or in reference to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually used in reference to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0023] See also Figure 1-4 , the utility model provides the following technical solutions:

[0024] Specifically, it refers to an efficient gas dehydration device for a nitrogen making system, including a dehydration shell 1, an outer surface of the dehydration shell 1 is fixedly connected with an outlet pipe 2, one end of the outlet pipe 2 passes through the dehydration shell 1, an outer surface of the dehydration shell 1 facing away from the outlet pipe 2 is fixedly connected with an inlet pipe 3, one end of the inlet pipe 3 passes through the dehydration shell 1, and the inlet pipe 3 is arranged at the lower side of the outlet pipe 2, an internal plate 4 is fixedly installed in the dehydration shell 1, the internal plate 4 is located between the inlet pipe 3 and the outlet pipe 2, and a dehydration filter element 5 is fixedly installed on the lower surface of the internal plate 4. The dehydration filter element 5 is an existing known technology and will not be described in detail here. The upper side of the dehydration filter element 5 passes through the upper surface of the internal plate 4. When in use, the inlet pipe 3 introduces air into the dehydration shell 1. After the air passes through the dehydration filter element 5, the dehydration filter element 5 separates the gas and moisture in the air, and the separated gas is finally transported to the nitrogen making system through the outlet pipe 2.

[0025] Specifically, a bottom plate 6 is fixedly installed on the lower side of the dewatering filter element 5, and a first pulley 7 is sleeved on the outer surface of the bottom plate 6. A connecting plate 8 is fixedly connected to the upper surface of the first pulley 7. A scraping brush 9 is fixedly installed on the surface of the connecting plate 8 on one side close to the dewatering filter element 5. The other side of the scraping brush 9 contacts with the outer surface of the dewatering filter element 5 and slides. When the dewatering filter element 5 separates the moisture in the air, the scraping brush 9 can scrape off the water droplets attached to the surface of the dewatering filter element 5, thereby avoiding the problem of excessive water droplets adhering to the surface of the dewatering filter element 5 and causing the filter pores to be blocked, thereby further ensuring the long-term use effect of the dewatering filter element 5.

[0026] Specifically, the inner ring of the first pulley 7 is fixedly connected with an annular slider 10, and the outer surface of the base plate 6 is provided with an annular groove 11. The annular slider 10 extends into the annular groove 11 and slides in the annular groove 11. Therefore, when the first pulley 7 rotates on the outer surface of the base plate 6, the annular slider 10 slides in the annular groove 11.

[0027] Specifically, a driving mechanism is provided in the air inlet pipe 3, and the driving mechanism includes a rotating shaft 12. The upper end of the rotating shaft 12 is rotatably connected to the top wall of the air inlet pipe 3, and the lower end of the rotating shaft 12 is fixedly connected to the fan blades 13. When the air inlet pipe 3 transports gas into the dewatering shell 1, the airflow will form a thrust on the blades of the fan blades 13, so that the fan blades 13 drive the rotating shaft 12 to rotate.

[0028] Specifically, a second pulley 14 is fixed on the outer surface of the rotating shaft 12, and the second pulley 14 is at the same horizontal position as the first pulley 7. A transmission belt 15 is connected between the first pulley 7 and the second pulley 14. When the rotating shaft 12 rotates, the second pulley 14 will rotate synchronously with the rotating shaft 12, so that the transmission belt 15 can synchronously drive the first pulley 7 to rotate. The above structure is combined with airflow to achieve the purpose of controlling the scraping brush 9 to clean the outer surface of the water removal filter element 5, and no additional electric components are required, so that the mechanism has good environmental value and environmental significance.

[0029] Specifically, the diameter of the second pulley 14 is one fifth of the diameter of the first pulley 7. Therefore, according to the principle of saving effort when a small pulley drives a large pulley, the problem of the first pulley 7 being too heavy and the airflow being unable to drive the fan blades 13 to rotate is avoided, further ensuring the stability of the drive mechanism during operation.

[0030] The working principle of the efficient gas dehydration device for the nitrogen production system provided by the utility model is as follows: when in use, the air inlet pipe 3 introduces air into the dehydration housing 1, and after the air passes through the dehydration filter element 5, the dehydration filter element 5 separates the gas and water in the air;

[0031] At the same time, the airflow will form a thrust on the fan blades 13, so that the fan blades 13 drive the rotating shaft 12 to rotate, and the second pulley 14 will rotate synchronously with the rotating shaft 12, so that the transmission belt 15 can synchronously drive the first pulley 7 to rotate, and the scraping brush 9 slides on the surface of the dewatering filter element 5 to scrape off the water droplets attached to the surface of the dewatering filter element 5.
