Waste heat recovery water circulating device

Abstract

The invention belongs to the technical field of household life equipment and discloses a waste heat recovery water circulating device. The waste heat recovery water circulating device comprises a hearth, a smoke pipe, a three-way valve, a heat exchanger, a control valve, a water pump, a water tank, temperature sensors, a controller, a control body, a control pipe, a movable body, a spring and a fixed body, the three-way valve is arranged at the joint between a manifold and the smoke pipe, the heat exchanger is arranged at the top of the smoke pipe, one end of the movable rod is firmly connected with the first movable body, the other end of the movable rod is firmly connected with the second movable body after passing the fixed body, and the right wall surface of the first movable body is connected with the right wall surface of the control body through a spring. According to the waste heat recovery water circulating device, the controller is capable of controlling the open / close of the three-way valve according to signals gathered by two temperature sensors so as to use the exhaust waste heat in the smoke pipe to heat household water. The waste heat recovery water circulating device is reasonable in design, simple in structure and suitable for designing household waste heat recycling systems.

Description

technical field [0001] The invention belongs to the technical field of domestic living facilities, and in particular relates to a waste heat recovery water circulation device capable of recovering waste heat from a stove. Background technique [0002] The demand for domestic hot water is indispensable in people's lives. Domestic hot water is used in bathing, kitchen and bathroom, cooking, etc. In rural households in China, people generally use solar water heaters to make domestic hot water by using light and heat, or directly use other heating methods, such as burning fuel or electric heating. However, whether it is solar energy or other heating methods, there are different disadvantages. For example, the use of solar energy is greatly affected by the weather: on cloudy and rainy days, the temperature of hot water is insufficient and high-grade electric energy is often used for auxiliary electric heating; When the temperature of hot water reaches almost 100 degrees, what is...

However, whether it is solar energy or other heating methods, there are different disadvantages. For example, the use of solar energy is greatly affected by the weather: on cloudy and rainy days, the temperature of hot water is insufficient and high-grade electric energy is often used for auxiliary electric heating; When the temperature of the hot water reaches almost 100 degrees, what is produced cannot be used but has to be allowed to evaporate naturally, wasting water resources

And other heating methods need to adopt other energy sources (such as electric energy or coal burning, fuel, etc.), which is not conducive to saving energy.
