Abstract

The invention discloses a double air inlet heat-exchange device for a condensation type gas water heater, which comprises a casing, a condensed water collecting box, a condensation heat exchanger and a smoke collecting cover, wherein the casing is of a two-end through structure. A side wall of the condensed water collecting box is provided with a flue gas inlet, the bottom of the condensed water collecting box is provided with a condensed water outlet pipe, a condensed water baffle preventing the condensed water from flowing out of the flue gas inlet is arranged right above the inner side of the flue gas inlet, the smoke collecting cover is provided with a flue gas outlet, the condensed water collecting box is arranged in the casing, the condensation heat exchanger is arranged in the condensed water collecting box, the smoke collecting cover is buckled on the condensed water collecting box, and the condensation heat exchanger is sealed in the smoke collecting cover. The double air inlet heat-exchange device solves the problem that a heat exchanger of an existing condensation type gas water heater is low in heat exchange efficiency, the heat exchanger is corroded due to overflow of the condensed water, the content of CO in the flue gas is too high due to airflow smoothness failure, and the like. The double air inlet heat-exchange device has the advantages that the heat exchange efficiency is high, the air flow is smooth, contents of CO and NOX in the discharged flue gas are low, the overflow of the condensed water is avoided, and the double air inlet heat-exchange device is easy to manufacture.

Description

technical field [0001] The invention relates to a heat exchange device for a condensing gas water heater. Background technique [0002] When ordinary gas water heaters burn at rated power, the flue gas temperature is usually around 180°C, CO, NO X The content is relatively high, and the water vapor in the high-temperature flue gas also contains about 15% of heat energy that is discharged to the outside. The efficiency of existing condensing water heaters is improved by condensing heat exchange, but the corrosion of condensed water will affect the service life of the product. Recovering latent heat is very effective for improving efficiency, energy saving and environmental protection, and reducing the corrosion of condensed water is of great significance for improving the service life of products. [0003] When the gas is burned, a large amount of water vapor will be produced. According to calculations, 1m 3 The natural gas can produce 1.6Kg of water when it is completely ...
