Discussion on steam pipe network design
Thread Content
Steam is indispensable for chemical production, and the steam pipe network of each pressure level is staggered. In order to optimize the operation of energy conservation, how to arrange the steam pipe network is particularly important. Please discuss it and provide your own suggestions or opinions.
It should be produced and used by oneself as much as possible, which can reduce the loss of steam heat during transportation. During the transportation process, superheated steam should be used as much as possible to prevent water from being carried during transportation and causing damage to pipelines and valves. The layout of public works is similar, with the main road coming in first, and then the branch roads leading to various steam points. The most important considerations in design are drainage and thermal expansion. good luck. . . .
1. Steam pipe networks generally transport superheated steam, and saturated steam is preferred for thermal equipment. 2. Steam pipe network exhaust and hydrophobicity (filtration) are indispensable. 3. Straight pipes or swing pipes need to face upwards. 4. Steam pipe insulation needs to be well maintained. 5. Recycling of steam condensate - heat energy recovery and water recovery. I will write a few items for now, and I will add more when I think of it. It is very meaningful for everyone to participate in this discussion.
1. High, middle and low voltage should be distributed reasonably； 2. The design requires expansion bends ； 3. From high to low, the pressure can be reduced and connected to the grid; 4. The condensate must be fully recovered, especially those with large latent heat; 5. Protective and thermal insulation ； 6. Hydrophobic exhaust must be appropriate.
A few more important points to add: 1. Design of fixed brackets and sliding brackets for steam pipes 2. Determine the appropriate steam pressure pipe network according to the factory's products 3. A complete factory condensate recovery and use plan must be designed, otherwise it will be very energy-inefficient 4. Cold and frost protection must be done in winter 5. Pay attention to cold drawing construction in pipeline construction
