Description

Technical Field

[0001] The utility model relates to the technical field of coalescing dehydrators, in particular to a coalescing dehydrator used for producing hydrogen from natural gas. Background Art

[0002] The coalescer is composed of a metal shell with a coalescing filter element and a separation filter element installed inside, and is equipped with a drain valve, a drain valve, a differential pressure gauge, a safety valve, a liquid level gauge and other accessories. The liquid-liquid coalescer combines filtration and dehydration in one, and can not only filter out various tiny particles in the medium, but also can filter out moisture, fiber and suspended matter in the medium very well. It is an ideal oil purification equipment.

[0003] Some small water droplets that have not settled in time flow with the liquid to the separation filter element. The separation filter element is made of special materials and has good hydrophobic properties. The small water droplets are intercepted outside the filter element and aggregated into large water droplets to settle again, thereby ensuring the removal of water. The water that settles to the bottom of the shell is displayed by the liquid level gauge, and the water and dirt can be discharged regularly or irregularly through the drain valve. The oil flows from the outside of the filter element to the inside, and the medium that has separated the water is collected by the separation filter element tray and flows out from the separator outlet. Water and oil are discharged through different drainage ports.

[0004] A Chinese patent discloses a natural gas dehydration device (authorization announcement number CN 209759399 U). The patent technology can filter and separate natural gas by setting a coalescing filter layer and a separation filter layer inside the separator. The coalescing filter layer and the separation filter layer can filter and separate the natural gas, and the obtained impurities are output from the sewage pipe. However, they only fall by the gravity of water, and the filter screen is easily blocked for a long time, affecting the filtering effect. Therefore, the utility model provides a coalescing dehydrator for hydrogen production from natural gas to solve the problems raised in the above background technology. Utility Model Content
