The invention relates to the technique of water degassing and can be used to remove dissolved gases from water, for example oxygen in oil, energy, food, and other sectors of the national economy.

The purpose of the invention is to increase the degree of water degassing and reduce the cost of manufacturing the installation.

The drawing shows the installation of vacuum deaeration of water

The installation contains a degasser 1 having a water inlet nozzle 2, a water dispenser 3, a nozzle 4, a water nozzle 5, a gas outlet nozzle 6, a water level regulator 7, a sensor 8 of the lower limit level, a vacuum pump 9 that creates a vacuum in the degasser 1, a pump 10, supplying deaerated water to the consumer. In the upper part of the degasser 1, a truncated conical partition 11 is placed in the form of a plate. Above the plate 11 is a hydrodynamic spray 12, communicated with the pipe 2 water supply. The cavities above and below the partition 11 are interconnected by a pipeline 13.

The installation works as follows.

The source water under pressure of 0.2-0.4 MPa enters the degasser 1 through nozzle 2. Due to the energy of the fluid supplied from nozzle 2 to the hydrodynamic sprayer 12, the latter splits the liquid into small particles and the liquid in the form of a torch (a small cable size) enters the cavity above the conical partition 11. Due to the vacuum created in the degasser 1 by the vacuum pump 9, water droplets are released from the main part of the dissolved gases, fall on the conical partition 11 and the stack along the conical partition cial hole fed to distributor 3 which is partitioned to et.vodu

nozzle 4 evenly across the cross section of the degasser 1. The stack over the nozzle 4 in the form of films and droplets, the water due to vacuum is released from the gases remaining in it and enters the lower part of the degasser 1, from where it is fed to the consumer through the nozzle 5. The gas released in the cavity above the conical partition 11 enters the pipeline 13, which transports it to the cavity under the cohesional plate. Here, the gas is freed from splashes and droplet moisture (due to a decrease in its speed) and through pipe b is removed by vacuum pump 9 from the degasser. The gas b out of the water as it passes through the nozzle 4 is also removed through the nozzle b.

To regulate the water level in the degasser, a level 7 regulator is provided that maintains the water level within certain limits. If the level regulator fails and the water level in the degasser is lowered to the lower limit level, the sensor 8 of the lower limit level is triggered, which abnormally stops the pump, which takes water from the degasser 1.

Thus, the proposed device, by using the differential pressure of the liquid on the hydrodynamic sprayer and obtaining finely dispersed liquid flow in the cavity above the conical partition, allows removing 80% of the dissolved gas from the water at the preliminary stage of water degassing and then only 20% comes to the nozzle the remaining gas, which in turn, decreases significantly the amount of bulk nozzles in the degasser and, therefore, reduces the height and mg, the weight of the degasser.

Calculations show that in the proposed water deaeration plant, the mass of the bulk packing is reduced by 8 tons, the height of the degasser is reduced by 2.5 m,

the mass of the degasser itself is 2 tons. The installation of a conical plate requires minimal modifications and does not significantly affect the mass of the degasser, as it allows it to be made from a thin sheet (due to the equality of pressures above and below the plate).
