Power generation device by waste heat of gas water heater

Abstract

The invention discloses a power generation device by waste heat of a gas water heater, comprising a condensing gas water heater and a temperature difference power generation system, wherein the condensing gas water heater comprises a combustor, a combustion chamber, a heat-exchange coil, a high-temperature section heat exchanger and a condensing section heat exchanger; the combustion chamber is positioned below the heat-exchange coil; the combustor is positioned below the combustion chamber; the high-temperature section heat exchanger is positioned below the condensing section heat exchanger; the high-temperature section heat exchanger mainly comprises two corrugated plate bundles, a partition plate, a plate box, a water inlet connecting tube and a water outlet connecting tube arranged in a shell; the corrugated plate bundles comprise two metal plates which are oppositely and longitudinally arranged to form a water channel, convex corrugations and concave corrugations are machined on each metal plate, the convex corrugations are bulges machined on the metal plate towards the outside of the water channel; and the distance between the two corrugated plate bundles is 2-6mm. In the invention, the temperature difference between high-temperature fume and sanitary water is used, and thermoelectric conversion is carried out by a temperature difference chip power generation module, thus realizing efficient utilization of the fume waste heat of the gas water heater, and achieving the purposes of energy conservation and environmental protection.

Description

technical field [0001] The invention relates to a waste heat power generation device, in particular to a gas water heater waste heat power generation device; it is a thermoelectric power generation device used for gas water heater waste heat recovery. The power generation device is used in the gas water heater industry to realize the efficient utilization of the waste heat of the flue gas of the gas water heater and improve the quality of the gas water heater. Background technique [0002] With the deepening of building a "resource-saving" and "environment-friendly" society, energy conservation and environmental protection have become a common problem faced by human beings in the 21st century. China is at a critical stage of sustainable development, and it is of great significance to fully recycle low-grade energy, waste heat, and waste heat energy. Our country is very short of energy, the utilization rate of energy is low, and various industrial waste heat, waste heat and ...
