Since obtaining the patent design of liquid ring vacuum pump, we have been constantly committed to the development and research of this product, and improve its application in various industries. With the continuous development of the power industry, the liquid ring vacuum pump and complete sets of units are continuously optimized according to the application requirements of various vacuum pumps in this field, which gradually reduces the cost of power generation and greatly improves the efficiency of power generation.

 

Application of vacuum pump in power industry: condenser vacuumizing, vacuum water absorption, flue gas desulfurization, fly ash transportation, turbine sealing pipe exhaust.

 

Condenser vacuumizing

The vacuum pump and complete set can be used for the two processes of vacuumizing and vacuum maintaining of condenser.

In the stage of vacuum pumping, the air and other non condensable gases in the condenser are pumped out when steam is not introduced into the condenser; in the stage of vacuum maintenance, the vacuum pump continues to work to extract the leaked dry air during the operation of the condenser, so as to maintain the back pressure of the condenser at the Zui optimal working point, ensure the high efficiency operation of the steam turbine and improve the thermal efficiency of the power plant. The optimized 2BV and 2be series liquid ring units can meet the users' reliable operation under various complex working conditions.

 

Vacuum water absorption

In this regard, the vacuum pump is used to keep a siphon in the cooling water system of the power generation equipment, so that the cooling water circulating pump can keep working at the design flow rate and the power consumption is the lowest. Liquid ring pump is an ideal choice in this aspect.

 

Flue gas desulfurization

When flue gas is desulfurized, 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 produced by filtration will enter into the vacuum pump. The liquid ring pump uses water as the working medium, and there is a large gap between the components, which can effectively operate well under this working condition, and meet the needs of customers. It is an ideal choice for users.

 

Fly ash transportation

The fly ash is transferred from the hopper of the vacuum cleaner to the central drying collection point by means of fluid transportation under vacuum. The main advantages of this kind of transfer system are: since the flying dust is transferred under vacuum, any leakage will be accompanied by air, and the flying dust will not be discharged out. The liquid ring pump has the ability to bear the flying dust into the pump, which is the best choice of transportation equipment for Zui.

 

Turbine sealing pipe exhaust

Steam turbine shaft is sealed by sealing tube to avoid air leakage. These seal tubes are sealed with steam. In order to achieve its design performance, liquid ring pump must be used continuously to remove excess steam and condensate.

 

Vacuum exhaust

Before the boiler water enters the system, the exhaust treatment must be carried out, usually by degasser. A vacuum device is placed on the degasser, and the prepared water flows through the vacuum device to remove all dissolved gases before entering the system.

 

Exhaust Geothermal Gas

Similar to the condenser exhaust, the discharge of geothermal gas includes the discharge 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 lot of corrosive gas. These gases must be discharged in the most effective way possible.
