Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Depend on figure 1 It can be seen that the condensing gas water heater includes a condensing gas water heater body 1 , a hot water internal circulation heat exchange system 2 and an electric control cabinet 3 . The body 1 of the condensing gas water heater passes through the water outlet flange 1-2-3 of the lower box, the water inlet flange 1-4-4 of the spray water inlet main pipe, and the water inlet flange 2-3 of the hot water internal circulation pipe. The water outlet flange 2-4 of the hot water internal circulation pipeline is connected with the hot water internal circulation heat exchange system 2. The electric control cabinet 3 communicates with the burner 1-3-1 in the condensing gas water heater body 1, the hot water internal circulation pump 2-1 in the hot water internal circulation heat exchange system 2, various operating parameters, ...

Abstract

The invention discloses a condensing gas water heater which comprises a condensing gas water heater body (1), a hot water internal circulation heat exchanger system (2) and an electronic cabinet (3). The condensing gas water heater body (1) is connected with the hot water internal circulation heat exchanger system (2) through a lower box water outlet flange (1-2-3), a spraying water inlet main pipe water inlet flange (1-4-4), a hot water internal circulation pipeline water inlet flange (2-3) and a hot water internal circulation pipeline water outlet flange (2-4). The electronic cabinet (3) is connected with a combustion engine (1-3-1) in the hot water internal circulation heat exchanger system (2), a hot water internal circulation pump (2-1) in the hot water internal circulation heat exchanger system (2), operating parameter sensors and security monitoring and control parameter sensors through cables and leads. The condensing gas water heater has the advantages of greatly improving flue gas heat exchange efficiency, lowering exhaust gas temperature and improving air preheating temperature by adopting a radial heat pipe fresh air preheater; increasing filtering area, reducing escape amount of hot water and greatly improving efficiency by adopting an efficient flue gas dehydration device.

Description

technical field [0001] The technical solution of the present invention belongs to the field of water heaters, specifically, it belongs to the field of water storage heaters with water sleeves surrounding several combustion chambers, and belongs to F24H1 / 24 according to the International Patent Classification. Background technique [0002] Existing gas-fired water heaters, such as my country's patent No. ZL201120158666.1, titled "A Condensing Gas-fired Water Heater with Air Preheating", include an air preheater, a heat exchange box, a deflector, Combustion tube elbow, water collection tank, spray branch pipe with multiple nozzles, explosion-proof pressure relief movable cover, muffler cover. The flue gas is sprayed into the heat exchange box from the combustion tube elbow, covered by dense water mist, passes through the long serpentine flue formed by the deflector, the flue gas is fully cooled, and passes through the stainless steel chip wire filter at the lower part of the fl...
