Liquid ring vacuum pump seawater desalination system

Everyone is paying attention to low-carbon life, and the best and most cost-effective low-carbon life is to use the existing resources of nature to integrate and use, such as solar energy, wind energy, bio-energy and geothermal energy, etc., like using wind power to generate heat from solar energy. Or the desalination of seawater not only saves costs, but also greatly reduces the pressure on the earth and makes a great contribution to environmental protection.piston-vacuum-pump-in-plastic-degassing

The use of solar energy for desalination is an effective method to solve the shortage of freshwater resources in China. There are many methods for desalination of solar energy. In order to reduce the evaporation temperature of seawater, vacuum pump is usually used to achieve negative pressure evaporation, thereby reducing the boiling temperature of seawater boiling. The function of vacuum pump can also be Changing the flow of water vapor facilitates heat transfer and condensation. Therefore, the vacuum pump plays a crucial role in the desalination system. Its working performance has a great impact on the whole seawater desalination system. Therefore, the vacuum pump is required to have reliable performance, stable operation, low energy consumption, high vacuum, and sufficient pumping rate.

At present, vacuum pumps for seawater desalination mainly include water jet vacuum pumps and liquid ring vacuum pumps. The working principle of water jet vacuum pumps is to extract gas by high-speed water flow generated by pressure difference, and has a simple structure to absorb condensed gases such as water vapor. Features, but its low efficiency and high power consumption. The liquid ring vacuum pump relies on the eccentric impeller rotation in the pump casing to throw water into the pump casing to form a concentric water ring with the pump casing. The water ring and the rotor blade form a periodic volume change to suck, compress and discharge the gas. When the vacuum is high, the pumping speed is large, and the condensed gas such as water vapor can be sucked. Compared with the water jet vacuum pump, the power consumption is low, the efficiency is high, the structure is compact, and the vacuum generated is sufficient to meet the desalination requirements. The liquid ring vacuum pump is more suitable for the negative pressure seawater desalination system.

The liquid ring vacuum pump is applied to the solar desalination system, and a new type of solar desalination device is proposed. Through the experimental study on the working performance of the liquid ring vacuum pump, the variation law between the system vacuum degree and the pumping speed is obtained, which is the seawater desalination system. The theoretical basis is determined by matching the performance of the vacuum pump and determining the optimal operating parameters.roots-vacuum-pump-manufacturing
