Regarding the use of hydrogen pipelines for water transport, most manufacturers currently rely on water seals to enable automatic water delivery, which is safer
A safer option is to use the water seal device mentioned on the second floor, while a simpler approach is to install a drain at the lowest point of the pipeline for manual drainage. We use manual drainage.
This method tends to freeze in the winters of the north, leading to unstable production, unless additional protective measures are taken. This post was last edited by sdajie on 2008-1-13 15:23]
Generally, it involves guided drainage combined with manual drainage, and frequent drainage is also required
I personally agree with this approach! Another item is the hydrogen buffer tank, from which water should be drained regularly through its drain valve. This post was last edited by sdajie on 2008-1-13 15:26]
For the hydrogen buffer tank, a salt dehydration tank can be installed in front of it to allow for regular discharge. That’s how our company does it: in summer, it’s played once per shift, while in winter it’s played every 2 hours; moreover, steam is used for insulation in winter.
1. If the synthesis furnace is located close to the hydrogen distribution station, it is sufficient as long as the distribution station has a hydrophobic coating; 2. If the distance is large, our approach is to install drainage points before the flame arrester, buffer tank, and before the material enters the furnace, in order to drain water regularly. The specific frequency needs to be determined based on the temperature, as the temperature of the distribution station remains relatively stable; the greater the temperature difference, the more saturated water will precipitate ; 3. If it is for long-distance transportation and the local winter temperatures are low, then measures to remove water must be considered.
1. Install a safe water addition seal device. 2. Add a hydrogen buffer tank; install a drain at the lowest point and drain the water every half hour. Provide steam tracing for the hydrogen pipelines. Be careful when draining water to ensure it is done in the right amount, as releasing gas can cause fluctuations in hydrogen pressure, leading to potential dangers
Additional notes: 1. At the bends in the hydrogen pipeline and at the areas where access is required, tees or dead ends should be installed to collect and discharge water, thereby preventing incomplete drainage in the straight sections of the pipeline. :Lol. 2. By installing something similar to a tee on the hose that leads into the two-in-one furnace, it’s possible to drain the water from the hose, thereby ensuring a normal pressure difference when water enters the furnace. It was an idea we came up with ourselves, and it works quite well. :victory: Last edited by edc1233 on 2008-6-7 17:16 ]
Some manufacturers do it this way: 1. When the ambient temperature is above freezing point, low-point drainage is used, which can be done manually or automatically via a water seal. 2. When the ambient temperature is above freezing point, activate the dehydrating tank, which is generally installed after the pump’s outlet; solid alkali is used as the absorbent, and inspections and discharge at various drainage points should be intensified.
Install a hydrogen buffer tank, and drain water regularly using the tank’s drain valve. Drainage of hydrogen pipelines is very important; poor management of it can cause fluctuations in the hydrogen chloride synthesis furnace
Let the hydrogen dehumidification tank (filled with pebbles) be used for water removal; a drain valve should be installed at the bottom of the tank. Water should be drained every 2 hours in summer and every 1 hour in winter. There should be no unevenities in the pipelines before hydrogen enters the furnace.
