Based on negative pressure suction condensate reuse device and its gas water heater

Abstract

This invention discloses a negative pressure suction-type condensate reuse device and its gas water heater. Its features include a condensing heat exchanger, an inlet solenoid valve, a water pump, an ejector, and a control valve. The water pump and inlet solenoid valve are respectively installed in the inlet pipe of the condensing heat exchanger. The condensing heat exchanger includes a vortex condensing chamber, a flue pipe, and a condensate pipe. The flue pipe is vertically installed inside the vortex condensing chamber, and the condensate pipe is coiled outside the flue pipe. A condensate outlet is located at the lower part of the vortex condensing chamber. An ejector is connected to the inlet pipe where the water pump is located, and the ejector is connected to the condensate outlet. The high-speed flow inside the ejector generates a low-pressure suction effect to absorb the condensate. This invention has good stability, eliminates the need for a condensate drain pipe, and is convenient for users to install and use.
