Abstract

Invention m. used at heat power plants in heating production boilers and heat networks for deaeration and water heating. The purpose of the invention is to increase hydrodynamic stability and improve the quality of deaeration. The inlet part of the nozzle 7 for draining deaerated water is placed in the space of the deaerator and made with an oblique cut, which allows maintaining a higher water level on the bottom of the deaerator while increasing the hydraulic load. The inlet and outlet sections of the drainage channel 6 of the non-evaporated water are located below the water level in the bubbling chamber 3 and below the inlet section of the nozzle 7. Such an implementation eliminates siphoning of the outlet water from the chamber in the drain channel and eliminates the causes of the destruction of the drain channel and the bubbling sheet 4. 1 .

The invention relates to heat and power engineering and industrial heat of water and can be used in thermal power plants in heating boilers and heat networks for deaerating and heating water.

The aim of the invention is to improve hydrodynamic stability and improve the quality of deaeration.

The drawing shows a deaerator, a cross-section.

The deaerator contains a water distributor 2 placed in the housing 1, a bubbling chamber 3, a bubbling sheet 4, a partition 5, a channel 6 for evaporating water, a nozzle 7 for draining deaerated water, the inlet part of which is placed in the deaerator space, made with an oblique cut, a nozzle 8 for the introduction of the heating agent, the pipe 9 for supplying the source water, as well as the pipe 10 for removal

Vacuum deaerator works as follows.

Chemically, the softened water enters the deaerator through pipe 9 to a partitioned water distributor 2 and jets to the initial portion of the bubbling sheet 4. In the jet compartment, the water is heated to a temperature close to the saturation temperature, and partially deaerated with steam formed from boiling overheated water, which It is fed through the pipe 8. After the treatment on the bubbling sheet 4, water is discharged from the deaerator through the pipe 7.

The overheated water entering into the bubbling chamber 3 boils up, the released steam forms a steam pad

The implementation of the nozzle 7 for discharging deaerated water with an oblique cut allows you to maintain a higher level of water at the bottom of the deaerator while increasing the hydraulic load, which increases the surface of water contact with the steam medium and provides additional discharge of non-condensing gases. Changing the water level on the bottom of the deaerator when the hydraulic load fluctuates leads to a corresponding smooth change in the height of the hydraulic shutter, through which non-evaporating water is removed from the bubbling chamber, which ensures optimum pressure drop between the steam spaces of the deaerator and bubbling chamber during various modes bubbling sheet, while deteriorating the quality of deaeration.
