Description

one

The invention relates to heat power engineering and industrial heating equipment, namely to thermal deaerators, and can be used for the degassing of water in thermal power plants and in industrial boilers.

The aim of the invention is to increase the hydrodynamic stability and improve the quality of deaerg. wide range of thermal hydraulic loads.

In the drawing, a schematic representation of the proposed deaeration column is shown.

The column contains installed in the housing 1 jet 2 and the bubbling 3 plates. A built-in steam-through valve 4 and a water drain device 5 adjoin the sparging plate 3. The nozzles 6 7 and 8 are connected to the housing 1 for supplying deaerated water, steam and discharge of the ball, respectively. A continuous bypass valve is installed between the jet plate 2 and the steam-retaining valve 4, which is made in the hydraulic seal formed by the tray 9 and lowered into it by the plate 10, the bottom of the tray 9 and the housing 1 are connected by a partition

12. The walls of the housing 1, the partition n bypass valve 4, jet

2 and bubbling 3 plates limit the inkjet compartment 13 of the column. Water through pipe 6 is fed to the water intake Kaiviepy 12 and then to the jet plate 2; from the jet tray 2, the water is drained onto the bubble plate 3 and then into the iodine drain device 5. Steam is supplied through the nozzle 7 to the bottom of the deaeration column and enters through the holes. of the bubble plate 3 into the jet compartment 13. As the load of the hydraulic load increases, the differential pressure on the bubble plate 3 increases, and the speed increases accordingly.

steam out through its openings. At the same time, the vapor carries liquid drops into the over-compartment space of the jet compartment 13, which can reduce e (the deaeration efficiency and the hydrodynamics of the column deteriorate. Executing a column with a continuous bypass valve avoids an undesirable increase in the rate of steam outflow through the holes of the bubbling plate and keep the steam flow rate at the barbo bar at the optimum level. The valve tripping moment is controlled by the value H of the depth of the plate 10 in the pan 9, With a further increase in load The control measures the built-in steam supply valve 4.

Thus, installing an additional continuous bypass valve in the column allows maintaining optimal steam consumption for sparging in a wide range of loads, which, in turn, provides hydrodynamic stability and the required quality of deaeration in these modes.
