Variable sound speed booster heat exchanger is a mixed type steam water heat exchange equipment

Variable sound velocity booster heat exchanger, also known as two-phase flow jet heat exchanger, is widely used in various fields of steam water heat exchange. Developed independently by Luoyang Blue Ocean Industry Co., Ltd. in China. It is powered by steam, and through the compression and mixing of steam and water, the water temperature instantly rises. It uses pressure shock wave technology to achieve the effect of no external pressure boosting. The significant energy-saving and boosting characteristics greatly reduce the user's operating costs and can replace traditional heat exchangers.

The variable sound velocity booster heat exchanger is a mixed type steam water heat exchange equipment. Steam is treated with adiabatic expansion technology and introduced into the mixing chamber in a jet state. The heated water, which has undergone membrane treatment, is uniformly mixed under the action of steam impact, forming a steam water compression mixture with a certain calculated volume ratio. When its instantaneous compression density reaches a certain value, a two-phase fluid field phenomenon is formed. Under the excitation of the field state, the sound velocity value of the mixture undergoes a transitional transition beyond the critical sound barrier, and a large number of pressure shock waves erupt. The unidirectional conduction characteristics of the pressure shock waves cause the hot water that reaches the design temperature to experience a pressure increase in a constant cross-section pipeline without reflux. The variable sound velocity boosting heat exchange technology is a dual effect of "instantaneous heat transfer+no external pressure boosting" that is forced by the ordered intensification of the two-phase fluid field.

1. Corrosion protection

The application of heat exchangers in the refining industry is very extensive, and their importance is also evident. The utilization rate of heat exchange equipment directly affects the efficiency and cost of the refining process. According to statistics, heat exchangers account for about 1/5 of the investment in chemical construction. Therefore, the utilization rate and lifespan of heat exchangers are important issues worth studying. From the perspective of the causes of damage to heat exchangers, corrosion is a very important factor, and corrosion in heat exchangers is widely present. Solving the corrosion problem effectively is equivalent to solving the root cause of heat exchanger damage. To prevent corrosion of heat exchangers, it is necessary to understand the root cause of corrosion. The reasons for corrosion of heat exchangers will be discussed from the following aspects.
