Specific implementation mode
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, a kind of retracting device of synthesis ammonia steam condensate, including collecting tank 1, water pump A2, cooling tower 4,
It is characterized in that：The collecting tank 1, water pump A2, cooling tower 4 are sequentially connected, and the water inlet and water outlet of the water pump A2 pass through
3 connection of bypass is adjusted, is equipped with heat exchanger and air-cooled water tower in the cooling tower 4, the water inlet of heat exchanger connect with water pump A2, changes
The water outlet of hot device is connect with air-cooled water tower, gas making equipment, sulfur recovery unit, the methanol that collecting tank 1 passes through pipeline and synthesis ammonia
The connections such as rectifying device, by these equipment, generated steam condensate is led in collecting tank 1 in process of production, passes through water pump
A2 pumps steam condensate to cooling tower 4, and in cooling tower 4, the temperature of steam condensate at this time is first led at 80 DEG C or so
It crosses heat exchanger to exchange heat, for the desalted water or domestic water of preboiler, improves the utilization rate of thermal energy, it is cold after heat exchange
Condensate is cooled down by air-cooled water tower, to prevent the steam condensate of overheat from influencing the filter effect of filter 6 and use the longevity
Life needs the working flow for reducing water pump A2, when the working flow of water pump A2 when the steam condensate in collecting tank 1 is less
When less than metered flow about 30%, cavitation erosion is easy tod produce in water pump A2, and the temperature of steam condensate is more held at 80 DEG C or so
It is also easy to produce cavitation erosion, cavitation erosion can damage the impeller of water pump A2, the service life of water pump A2 be reduced, when the workflow of water pump A2
When measuring relatively low, some vapor condensate liquid that water pump A2 is exported is led back to the entrance of water pump A2 by adjusting bypass 3, makes water pump A2 can
To be operated in the higher operating status of flow, cavitation erosion impeller is prevented.
Further include filter 6, desalination water tank 7, circulating water pool 8, the water inlet of the filter 6 passes through water pump B5 and cooling
Tower 4 connects, and the water outlet of filter 6 is connect with desalination water tank 7 and circulating water pool 8 respectively, and steam condensate is dropped by cooling tower 4
Wen Hou is pumped to filter 6 by water pump B5, and filter 6 is reduced by the filtering of the materials such as activated carbon in steam condensate
Impurity is then sent to the storage of desalination water tank 7, and desalination water tank 7 uses sealing structure, the oxygen in can preventing air in storage
Be dissolved in steam condensate with substances such as carbon dioxide, processing cost can be reduced in reuse, in use, steam condensate into
Enter desalination water tank 7 or enter in circulating water pool 8, by desalination, deoxygenation and etc. after send to water conservancy project sequence.
