Condenser vacuum, vacuum water absorption, flue gas desulphurization, fly ash transportation, turbine confidential sealing, exhaust, vacuum exhaust, exhaust heat.
With the continuous development of the power industry, the water loop vacuum pump and set of sets have also been optimized for various applications in this field, making the cost of power generation reduced gradually and greatly improving the efficiency of power generation. At present, the water ring vacuum pump in the power industry thousands of installed performance has been in China.
1. Condensers evacuated
Vacuum pump and set of units can be used for the vacuum and vacuum maintenance of the condenser two processes. The vacuum stage, the initial vacuum in the condenser that has not been introduced into the condenser, and the air in the condenser and other non condensing gases. In the vacuum maintenance stage, the vacuum pump continues to work to extract the leaked dry during the operation of the condenser. Air. Maintain condenser backpressure at the best working point to ensure the efficient operation of the steam turbine and improve the thermal efficiency of the power plant. The optimized TC, AT and 2BW series of liquid ring units can satisfy users' reliable operation under various complicated working conditions.
Two. Vacuum water absorption
In this respect, the vacuum pump is used to keep a siphon in the cooling water system of the power generation equipment, so that the cooling water circulation pump can be kept at the design flow and the power consumption is the lowest. The water ring vacuum pump is an ideal choice in this regard.
Three, flue gas desulfurization
When the flue gas is desulphurized, the gypsum slurry will be produced. It needs to be dehydrated by vacuum belt filter to form a gypsum product. Some impurities, water vapor and a small amount of water produced by the filter will enter the vacuum pump. The liquid ring pump uses water as the working medium and there is a large gap between the components. It is a good choice for users to run well enough to satisfy customers' needs.
Four. Fly ash transportation
In the vacuum, the fly ash is transferred from the vacuum funnel to the central drying collection point by means of fluid transportation. The main advantage of this delivery system is that any dust leakage is accompanied by air entry and the dust will not be discharged outwards. The pump has the ability to withstand dust entering the pump, and is the best choice for conveying equipment.
Five, turbine confidentiality sealed off the exhaust
Steam turbines seal the shaft with a sealing tube to avoid air leakage. These seals are sealed with steam. In order to achieve its design performance, it is necessary to continuously remove excess steam and condensate.
Six. Vacuum exhaust
Before the boiler water enters the system, the exhaust treatment must be carried out, usually using the degasser. Place a vacuum device on the degasser, prepare the water flow through the vacuum device, and remove all dissolved gases before entering the system.
Seven. Expulsion of hot gas
Similar to the condenser exhaust, the exhaust gas includes 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, which contains a lot of corrosive gases. The most effective way to discharge these gases must be as far as possible.
