Description

j

The invention relates to a technique for the degassing of water and can be used to remove dissolved gases, in particular oxygen, from water in the oil, energy, and other industries — 5 liters of water.

Goal 1 "W. Acquired - Reducing the energy consumption of the installation in the winter."

The drawing shows the installation of 10 vacuum deaeration water.

The installation contains a degasser 1 having a water inlet nozzle 2, a sprinkler 3, a nozzle 4 (lower and upper) 5 water outlet nozzles 5 and 15. gas outlet 6, level controller 7, sensor 8 of the lower limit level, pumping device 9 vacuum pump in degasser 1, pump 10, pumping out water from the degasser 1, 20 vertical pipe 11 connected to a sealed container 12 with pipe 13 connected to the atmosphere or to the drain pipe 14, the peak 15 preventing the ingress of pipe 11 into the pipe 11 splash of water flowing from nozzle 4, mounted coax but inside the degasser there is a gipzoobrazny spreader 16, a heat jacket 17 with a nozzle 18 for exhausting the air, communicated with the atmosphere, a hermetic chamber 19 with a nozzle 20 for supplying air and a heater 21 installed inside the chamber and connected to the heat jacket 17 35 by means of a pipe 23 with a discharge line of the pumping device 9. To reduce heat loss, the degasser may be provided with heat insulation 24.

The installation works as follows.

The initial water enters the degasifier I through the water supply pipe 2 and through the sprinkler 3 enters the lower nozzle 4. The stack through the nozzle, water due to the vacuum created by the pumping device 9, is released from the gases dissolved in it and falling on the convex part of the spreading glass 16 enters the gap between the wall of the body of the degasser 1 and the spreader 16. The gap area is filled in such a way as to ensure a certain water velocity in the gap, which is necessary for working without freezing. The exit from the gap, the water through, for example, the bump stops, is directed upwards into the bulk of the water, providing a certain amount of water. The deaerated water through the outlet 5 of the degasser 1 is pumped to the consumer by the pump 10 and the sucked gases are removed from the degasser 1 through the outlet 6 by the evacuator 9.

During the operation of the installation in winter, a part of the gases from the discharge lines of the pump-down device 9 is directed through the nozzle 20 into the chamber I, where the gas is heated with the help of a heater 21 powered by electricity, steam or from any other coolant. The heated air through the pipeline 22 enters the heat jacket 17, filled from the outside of the body of the degasser 1 according to the height of the nozzle 4. After the shirt 17 passes, the air through the pipe 18 enters the atmosphere. After the pumping device 9 of the air,

corrects in chamber 19, and the excess air is vented to the atmosphere.

A regulator is provided for regulating the water level in the degasser I.

7-level, supporting water level within certain limits, and a sensor

8 lower limit, which will stop the pump emergency 10.

If the water level in the degasser 1 is abnormally lowered, the pipe 1 allows the water from the vacuum apparatus to drain unhindered, as the lower end of the pipe I1 is lowered under the water level in the sealed container 12 connected to the atmosphere by a pipe 13 to which the drain pipe 14 can be attached . Above the upper cut pipe 1I installed visor 15.

Dp reducing heat loss in her time and energy saving heater degasser and piping can be provided with heat insulation.

The proposed installation saves energy for water heating, since the replacement of the coolant from the water to the air in the i7 jacket allows the use of heat from the pumping device, and the heater 21 will only be intermittent

The ki is turned on by the temperature relay commands (not shown) installed in the jacket 17 and set to a certain temperature.
