Description

Technical Field

[0001] The utility model relates to the technical field of gas storage tanks, in particular to a small gas storage tank. Background Technique

[0002] In the production process of chemical fertilizers, especially in the preparation stage of synthetic ammonia, nitrogen in the air reacts with natural gas or other carbon sources under high temperature and high pressure to generate ammonia. In this process, not only ammonia is generated, but also the generation of other combustible gases may occur, such as hydrogen, carbon monoxide, etc.;

[0003] Therefore, it is necessary to collect the generated combustible gases. On the one hand, it can effectively reduce the safety accidents caused by the discharge of combustible gases. On the other hand, it can also recycle the combustible gases. For example, the Chinese utility model patent disclosed in the publication number CN208679138U: A reaction kettle for chemical fertilizer production. In this application, the combustible gases generated during chemical fertilizer production enter the air compressor through a hose. The air compressor compresses the combustible gases and guides them into the gas storage tank for storage, which not only prevents air pollution but also improves the recovery and utilization of energy. However, during chemical fertilizer production, some raw materials themselves contain a certain amount of moisture, and during the chemical reaction process of chemical fertilizer production, complex chemical reactions will occur between the raw materials, and these reactions may generate water as a by-product. Therefore, the generated combustible gases will contain a certain amount of moisture. When the combustible gases enter the gas storage tank, due to temperature changes, condensed water will appear, which will cause a certain amount of condensed water to remain in the gas storage tank. When the existing gas storage tank treats the condensed water, it is easy to discharge a large amount of combustible gases together with the condensed water, which is likely to cause deflagration, and at the same time, it will also damage the respiratory system of the operator.

[0024] As Figures 2-5As shown in the figure, a drain hole 18 is provided at the bottom of the storage ball seat 6. A partition seat 17 is fixedly installed inside the lower valve body 7. A tapered hole is provided at the central position inside the partition seat 17. A partition frame 12 is fixedly installed inside the bottom ring 11. Through the setting of the partition frame 12, a bottom limiting function can be provided for the subsequent installation of the pressure rod 10. A sealing ring 14 is fixedly installed inside the fixing seat 13. The output end of the motor 15 passes through the sealing ring 14 and extends into the lower valve body 7 and is fixedly installed with a gear 16. Through the setting of the motor 15 and the gear 16, the up and down displacement of the pressure rod 10 inside the lower valve body 7 can be controlled. A drain groove 19 is provided inside the upper valve body 8. A sealing groove 20 is provided at the bottom inside the drain groove 19. A first sealing plug 21 is fixedly installed at the top of the cross rod 9. A second sealing plug 22 is fixedly installed at the bottom of the cross rod 9.

At the same time, when the cross bar 9 moves downward, it synchronously drives the first sealing plug 21 to be inserted into the sealing groove 20, so that the storage ball seat 6 is isolated from the inner cavity of the gas storage tank 1. Then, the condensate water in the storage ball seat 6 is discharged through the lower valve body 7 and the partition frame 12. After that, when the motor 15 rotates reversely, the third sealing plug 23, the second sealing plug 22 and the first sealing plug 21 can be reset, so that the storage ball seat 6 is isolated from the inner cavity of the lower valve body 7 and communicated with the inner cavity of the gas storage tank 1.
