Description

Device capable of preventing flue gas condensate water and rainwater from flowing backward to generator equipment

Technical Field

The utility model relates to the technical field of condensate water collection, and particularly discloses a device capable of preventing smoke condensate water and rainwater from flowing backwards into generator equipment.

Background

The generator set is a power generation device for generating power commonly used in a thermal power plant for cogeneration. When the generator is stopped, a large amount of condensed water formed by saturated water vapor in the flue gas pipeline flows back into the turbocharger and the generator equipment, so that the equipment is damaged; in addition, positive pressure smoke generated by a running unit of the plurality of generators in a parallel installation mode is leaked by the smoke blocking valve, so that the smoke is strung into an inoperative generator, saturated water in a pipeline generates condensed water at a cold-hot alternation position in the smoke pipe and flows back into the generator to damage equipment, and the accessory, the labor and the shutdown bring great direct and indirect economic losses to power generation projects.
