The steam pipeline through which steam directly heats the water vibrates violently; can installing an expansion joint solve the noise problem?
No, this noise is produced by the rapid cooling of steam, as it changes from a gaseous state to a liquid state and its volume contracts sharply (by nearly 800 times). It is referred to as the air hammer phenomenon for reference.
No, the expansion joint will break very quickly. For applications where steam is used to heat water directly, it is recommended to use an injector to achieve rapid mixing; the pressure of the steam can also be utilized to accelerate the circulation of water
Causes of cavitation in liquid ring vacuum pumps and treatment methods?
Why is water added to the steam pipes? Reduce pressure? For the pressure-reduction ejector, find a design company to handle it.
You can go to the HaiChuan courses; there is a course specifically on cavitation that you can study.
For many years, steam has been used to heat water directly; there is no vibration. The steam pipes lead directly into the lower part of the tank through probes, and the steam enters the water after being depressurized by a control valve – again, without vibration, though there is some noise. You can search online for steam distributors, which are installed at the bottom of the steam pipes in sinks. It can also be designed according to the vapor mixer approach; there are many similar schemes for directly heating water with steam, and the choice and design depend on the process requirements.
