Beneficial effect:
1. water tank of the present invention is the collecting device of deaerated water, has the storage boiler feedwater, the change of confluent when absorbing varying duty, the function of maintenance balance.
The membrane deaerator that the present invention adopts is horizontal, header pipe type is exerted oneself greatly can be used for the shared oxygen-eliminating device of two units of large-scale unit or small-sized unit, reduces number of devices, reduces cost of investment.
The present invention all can satisfy the deoxygenation requirement when separate unit unit operation and two units move simultaneously, it is big that equipment adapts to load range, and can satisfy the needs of fixed pressure operation and sliding pressure operation.
Header pipe type membrane deaerator of the present invention is applicable to that various power plant comprise the boiler feed system of power plant for self-supply, is particularly useful for the low temperature water charging system, and the operating mode bigger in thermograde also can safely and steadily run; Distribute female tubular construction to simplify the outfit of equipment structure by the header pipe type feedwater, bring great convenience for manufacturing and installation.
Heat transfer of the present invention, mass transfer mode are different with atomization type, and it is heat transfer, mass transfer to be fused into one carry out simultaneously because will conduct heat, mass transfer fuses into one, so improved heat transfer efficiency greatly.
The special construction of rotating film type jet pipe of the present invention has determined this oxygen-eliminating device to have very strong deoxygenation ability and has adapted to the varying duty ability, especially the high dissolved oxygen of power plant, low temperature moisturizing there is extremely strong adaptive capacity, in the stable operation of the following all energy of the situation of 120% load and sub-load 〉=30%.
Water tank of the present invention is the collecting device of deaerated water, has the storage boiler feedwater, and the change of confluent when absorbing varying duty has the function that keeps balance.
The present invention changes the nature falling liquid film into powerful falling liquid film, has increased the renewal degree of liquid film, again because of liquid film along the powerful rotation of tube wall, entrainment a large amount of steam, strengthened heat exchange, heat transmission function.
Feed pipe of the present invention provides qualified high-quality water to boiler, reaches the oxygen corrosion that reduces unit equipment, the purpose that improves the thermal efficiency of unit.
