Design a U-shaped water seal
Thread Content
Design requirements: 1. The water seal height shall not exceed 1 meter. 2. Reach a pressure of 50 KPa for sealing. 3. Discharge volume: 2m3/h. 4. No special requirements for the material. 5. The water contains a small amount of dissolved CO2 (accounting for gas resistance). Current approach: 1. Six 1-meter U-tubes connected in series, with a total length of no more than 1 meter. II. Elbows are used in place of pipes between them. III. Install a control valve at the top elbow to prevent the formation of gas blocks due to dissolved gas. IV. Use DN50 pipes. I would like to ask the teachers: Is this design feasible? What other problems might exist? Is there a more reasonable design?
It is recommended to refer to the water seal for condensate water in the gas pipelines of steel mills. He placed multiple partitions inside a barrel, similar to series-connected “U”-shaped tubes. The partitions are arranged with one layer in contact with the top and one layer in contact with the bottom, and then water is added. An overflow port is installed at the highest point of the liquid level to discharge the excess water. At the bottom of each water flow isolation device, there is a sewage valve (or blind flange) for removing sediment. This water level can be made higher, with fewer partitions; no specific calculations have been done, for reference only.
The weld seam is too long; the principle is the same – it allows space to be saved in a limited area. Thank you for your reply.
Have there become fewer people from HaiChuan, or have the questions become simpler so that people don’t want to reply? I hope more people will offer suggestions. Thank you!
