DEVICE FOR DEGASSING OF HOT WATER USED IN THE SYSTEMS OF THE WATER HEATING Russian patent published in 2005 - IPC

FIELD: industrial and municipal systems of water heating; equipment of industrial and municipal water heating systems water purification from the gasses dissolved in it.

SUBSTANCE: the invention presents a device for the hot water degassing in the systems of water heating, that may be used in industrial and communal heating systems. The device for degassing of the hot water in a water heating system contains an accumulating container with the liquid level signaling tool and with a branch pipe for delivery of the degassed water to consumers, the branch pipes for feeding the water for degassing and for withdrawal of the air-steam mixture, a drain line in the accumulating container, the chiller of the air-steam mixture, the systems of degassing and suction of the air-steam mixture, the first and the second ejectors of the different productivity. At that each of them has its own press pump, The press pump of the first ejector of the greatest productivity is made regulated. The first and the second ejectors are capable to form the high-speed streams including the supersonic streams. The system of suction of the air-steam mixture is formed by the second ejector with the press pump and the chiller of the vented steam, which is made in the form of a heat exchanger preheating the water being added in the water heating system after its passing through the consumers for maintenance of the level of the water in the accumulating container controlled by the signaling device. The degassing system is formed by the first ejector, a branch pipe of water delivery for degassing from consumers to the first ejector, a branch pipe of withdrawal of the air-steam mixture connecting the zones of rarefaction of the first and the second ejectors, a sink main additionally equipped with a screen into the accumulating container of the degassed water from the first ejector. The branch pipe of water delivery for degassing is equipped with an adjustable press pump of the first ejector, which is installed for maintenance of a constant pressure drop on the first ejector. The branch pipe of feeding of the degassed water to consumers is additionally equipped with mounted in series follow-up arranged in succession by a pumping station with the controlled productivity directly depending on the level of liquid in the accumulating container, determined by the signaling system, and the hot-water heater. The chiller of the vented steam is additionally equipped with a drain branch pipe discharging the excesses of water accumulated in the chiller of the vent steam in the water added in a heating system. The technical result of the given invention is creation of the power saving, effectively operating device for degassing of the hot water in the heating system, increasing alkalinity of the water, destroying a biological component, economically consuming the heat accumulated by the chillers of the vent steam, equipped with the structural members for removal of the solid fractions formed in the process of heating the water.

EFFECT: the invention ensures creation of the power saving, effectively operating device for degassing of the hot water in the water heating system.
