Description

This invention relates to devices for separating gases from water from heat networks.

The purpose of the invention is to intensify the process of desorption of dissolved gases.

FIG. 1 is a schematic diagram of the connection of the device to the heat network; in fig. 2 is a section A-A in FIG. one; FIG. 3 shows the core of the device, a longitudinal section j in FIG. 4 - section bb in fig., 3 „

The device includes a housing 1, a circulation pipe 2, a pipe 3, a flange 4, a selection pipe 5, a check valve 6, valves 7 and 8, a pipe 9 of the heat network, a nozzle 10, a pin 11, a bolt 12, a nut 13, a cover 14 housing, guiding the partition 15, the air outlet 16, the nozzle cover 17, the inlet 18, the filter cover 19 and the filter element 20.

The device works in the following way.

Under the action of the dynamic pressure in the supply network of the heat network, water through the sampling pipe 5 through the valve 8 enters the nozzle 10, installed perpendicular to the axis of the housing 1. At the nozzle exit

net water and gases dissolved in it are sprayed and moving along. the baffle plate 15 enters the chamber with the filtering element 20 impregnated with the hydrophobic one. silicone fluid. The impregnation of the filter element 20 transmits gases, oxygen, carbon dioxide and hydrogen dissolved in the supply water, and water and water vapor are retained in the lower part of the housing.

Passing through the filter element, the gases are directed to the air outlet pipe 16, from which they are removed 15 through the outlets. The water-vapor fused in the filter housing through the circulation pipe 2 and the check valve 6 are returned to the pipe heat.

20 of the network 9. As the housing 1 is emptied, new portions of the network water are fed to it. The device is installed in heating chambers on the supply pipeline of the main highways in the wiring areas of districts and quarters, as well as at the CHP or GRES on the supply pipeline, after the heating of the heating water.

The use of the proposed device allows to increase the durability of the heat network by reducing its internal corrosion.
