Application of Vacuum Pump in Electric Power Industry
Since the patent design of the liquid ring vacuum pump was obtained, it has been continuously devoted to the development and research of this product, improving its application in various industries. With the continuous development of the power industry, the liquid ring vacuum pumps and sets of units are constantly optimized to meet the application requirements of various vacuum pumps in this field, so that the cost of power generation is gradually reduced and the efficiency of power generation is greatly improved.
Application of vacuum pump in power industry: condenser vacuum pumping, vacuum water absorption, flue gas desulfurization, fly ash transportation, turbine sealed pipe exhaust.
Vacuum pumps and complete sets of units can be used for vacuum pumping and vacuum maintenance of condensers.
In the vacuum extraction stage, the air and other non-condensable gases in the condenser are extracted from the initial vacuum when the steam has not been introduced into the condenser; in the vacuum maintenance stage, the vacuum pump continues to work to extract the leaking dry air during the operation of the condenser, maintaining the condenser back pressure at Zui's best operating point, ensuring the efficient operation of the steam turbine and improving the thermal efficiency of the power plant. The optimized 2BV and 2BE series liquid ring units can satisfy the reliable operation of users under various complex operating conditions.
In this regard, the vacuum pump is used to maintain a siphon in the cooling water system of power generation equipment, so that the cooling water circulating pump can keep working at the designed flow rate with the lowest power consumption. The liquid ring pump is an ideal choice in this respect.
flue gas desulfurization
When flue gas is desulphurized, gypsum slurry will be produced, which needs to be dehydrated by vacuum belt filter to form gypsum products. Some impurities, water vapor and a small amount of water generated by filtration will enter the vacuum pump. Water is used as working medium in the liquid ring pump, and there is a large gap between the components. It can effectively run well under this working condition and meet the needs of customers. Want to choose.
Fly ash transportation
Fly ash is transferred from the vacuum cleaner funnel to the central drying collection point by means of fluid transport. The main advantage of this kind of transmission system is that as the dust is transmitted in vacuum, any leakage is accompanied by air entering, and the dust will not be discharged outward. The liquid ring pump has the ability to withstand flying dust entering the pump, and is the best choice of transportation equipment for Zui.
Turbine Secret Seal Pipe Exhaust
Steam turbines are sealed with sealing tubes to avoid air leakage. These sealing tubes are sealed by steam. In order to achieve its design performance, liquid ring pumps must be continuously used to remove excess steam and condensate.
Boiler water must be exhausted before entering the system, usually by degasser. A vacuum device is placed on the degasser to prepare water flow through the vacuum device and remove all dissolved gases before entering the system.
Exhaust Geothermal Gas
Similar to the condenser exhaust, the exhaust of geothermal gas includes the exhaust of air and other non-condensable gases from the steam space of the condenser. However, in geothermal power generation equipment, the steam used to drive the turbine comes from the earth and contains a large number of corrosive gases. These gases must be discharged in the most effective way possible.
