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

FIELD: industrial and municipal systems of hot water supply; devices for hot water purification from the gasses dissolved in it.

SUBSTANCE: the invention is pertaining to the methods and equipment for hot water degassing in the systems of hot water supply and may be used in industrial and municipal systems of hot water supply. The device for degassing of the hot water in the hot water supply 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, a 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 and the press pump of the first ejector having the greatest productivity is made controlled. 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 hot water supply system after its passing through the consumers for maintenance of the level of the water in the accumulating container determined by the signaling device. The degassing system is formed by the first ejector, a branch pipe of water delivery to the first ejector for degassing, a branch pipe of withdrawal of the air-steam mixture connecting the zones of rarefaction of the first and the second ejectors, a main of sink into the accumulating container of the degassed water from the first ejector. The branch pipe of water delivery for degassing is equipped with a controlled press pump of the first ejector and with an in parallel to it located pressure control valve, which are 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 a pumping station with the controlled productivity, that is directly depending on the level of the liquid in the accumulating container, determined by the signaling device. The accumulating container is additionally equipped from beneath with the system for the solid fractions removal. The technical result is creation of the power saving, device for degassing of the hot water in the system of hot water supply, increasing alkalinity of the water, destroying a biological component, economically consuming the heat accumulated by the chiller of the vent steam, equipped with the structural members for removal of the solid fractions formed in the process of the water heating.

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