What is the principle of hydrophobic expansion container? I believe that many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

The working principle of the hydrophobic expansion vessel is that when the drainage of the boiler and other equipment with high pressure enters the drain tank, the pressure is reduced through the expansion vessel (the expansion vessel is equipped with a cooling water pipe), and part of it is vaporized into steam.

Principle: when the drainage of boilers and other equipment with high pressure enters the drain tank, the pressure is reduced through the expansion vessel (the expansion vessel is equipped with cooling water pipes), and part of it is vaporized into steam.

After cooling, the unvaporized high temperature water is sent to the drain tank for use, which can reduce heat loss and soda loss. Steam can be sent into the plant low-pressure steam pipe network to be used.

Extended data

The function of bulk drainage expansion vessel is to receive steam turbine body drainage, main steam, reheat steam drainage, extraction steam system drainage, high accident drainage, low accident drainage, small turbine drainage, auxiliary steam drainage, deaerator overflow, etc. these hydrophobic capacity expansion, decompression, cooling, in order to recover the working fluid.

During operation, pay attention to the body expansion can not be over-temperature, vibration, so as not to damage the equipment, affecting the vacuum of the main engine and the operation of the unit, in addition, because of the great difference between the hydrophobic pressure and temperature, the hydrophobic is classified according to the pressure.

In order to prevent the drainage of different pressure from interfering with each other, causing accidents and stress increase, the drainage with similar pressure is connected to the same manifold. The unit has a high and low pressure drain box, which is arranged at the high pressure condenser.

The drainage system includes: automatic or manual control drainage; thermostat drainage; throttle orifice plate continuous drainage; also includes ventilation exhaust valve; valve stem leakage straight drain.

After reading the above, have you mastered the principle of hydrophobic expansion container? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
