Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen recovery equipment, in particular to an industrial waste hydrogen recovery and reuse device. Background Art

[0002] In the industrial production process, hydrogen is an important participant in many chemical reactions, but after the reaction, some hydrogen will often remain or be discharged as waste gas. If the hydrogen in the waste gas is not recovered, it will not only waste resources but also pose a potential threat to the environment. Therefore, the hydrogen in the waste gas will be purified through a series of processing equipment to make it meet the production requirements again;

[0003] In the industrial production process, hydrogen in the waste gas is often mixed with liquid impurities such as water and oil. If these liquid impurities are directly recycled without treatment, they may have an adverse effect on the subsequent production process, such as blocking pipelines and affecting the purity of hydrogen. Therefore, liquid impurities in the waste gas are removed by gas-liquid separation equipment to ensure the quality of the recycled hydrogen. For example, when using centrifugal gas-liquid separation equipment to remove liquid impurities such as water and oil in the waste gas, the spiral blades in the centrifugal gas-liquid separation equipment are used to force the gas to perform centrifugal cyclone motion to generate centrifugal force, thereby achieving the effect of gas-liquid separation. Although the spiral blades can produce forced cyclone action, so that the entrained droplets have enough centrifugal force to be thrown onto the outer wall of the cylinder, some gas will still be unable to fully separate the liquid, which will affect the gas-liquid separation effect.

DETAILED DESCRIPTION

[0024] like Figure 2 As shown, the gas-liquid separation tank 1 is fixedly mounted on the top and bottom of the top cover 4 with flanges, and the gas-liquid separation tank 1 and the top cover 4 are fixedly connected by flanges and bolts, and the gas-liquid separation tank 1 and the top cover 4 are also interspersed with a sealing ring 10;

[0025] like Figure 2-Figure 3 , Figure 6 As shown, the exhaust pipe 6 is in an inverted L-shaped structure, and a screw groove 12 is provided at the bottom of the exhaust pipe 6. The screw groove 12 is provided at the bottom of the exhaust pipe 6 to realize the rapid assembly of the buffer plate 9. The buffer plate 9 is in a truncated cone structure, and a screw ring 13 is fixedly installed at the bottom of the buffer plate 9. The screw ring 13 is threadedly connected in the screw groove 12, that is, the buffer plate 9 is movably installed at the bottom of the exhaust pipe 6 through the screw ring 13, and a plurality of through holes are provided in the buffer plate 9. With the arrangement of the buffer plate 9, the medium airflow centrifugally accelerated by the spiral blade 7 can be buffered;
