Questions about hydrogen reflux
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 21:33 A few days ago, everyone was discussing the setting of large chlorine reflux. Today I want to ask about the hydrogen reflux. The reflux setting of hydrogen in our unit is to return the hydrogen to a pipeline coming out of the scrubber, which is almost the inlet of the compressor. I saw in a book that there is such a setting, which is to go directly back to the scrubber. The pressure points of both settings are on the main pipe. I would like to ask, which of these two setting methods is better? # hcbbs
It is better to go after the scrubber because the scrubber is generally a spray type and does not require much air volume. The reflux after the tower is helpful to reduce the load of the scrubber and reduce mist entrainment.
We return from the pump outlet to the inlet of the washing tower. The control point is at the entrance of the water washing tower.
We perform backflow at the inlet and outlet of the pump. The pump may have a different form, so we use a Roots blower.
Support the 5th floor’s opinion. We also use this method and it operates stably.
Our return flow is the water mist collector outlet returning to the compressor inlet. The response is a bit laggy.
This is the main pipe in front of the machine that refluxes to the main pipe at the back of the machine. The pressure collection point is very sensitive to the reflux operation at the inlet of the water washing tower.
We use a water pump, and the return flow enters the tower from the distribution table to the hydrogen main pipe.
There is basically no difference in the effect. The automatic valve has more signal action, as long as it is sensitive.
