Abstract
The utility model discloses a flue gas waste heat recovery device, which comprises a spiral heat exchange tube which is arranged in a flue, wherein the spiral heat exchange tube comprises a water inlet and a water outlet, the water inlet is arranged on the lower end of the spiral heat exchange tube, the water outlet is arranged on the upper end of the spiral heat exchange tube, the water inlet is connected with a water storage device through a pipeline, and the horizontal position of the water storage device is higher than the horizontal position of the spiral heat exchange tube. The spiral heat exchange tube is arranged in the flue when adopting the technical scheme, glue gas generates heat exchange with the spiral heat exchange tube when entering the flue, and water in the spiral heat exchange tube is heated. The flue gas waste heat recovery device heats domestic water by utilizing waste heat of oven flue gas, saves energy and protects environment, and further can supply auxiliary heating for other water heaters simultaneously.
Description
Technical field
The utility model relates to flue gas waste heat recovery apparatus, is specifically related to a kind of flue gas waste heat recovery heat exchanger of spiral tube structure.
Background technology
Improving constantly of Along with people's living standard, water heater have also obtained using widely in the rural area not only in the city.Current water heater mainly contains electric heater, natural gas water heater and solar water heater.The above two need consume a large amount of electric energy or natural gas, exist energy consumption high, shortcomings such as not environmental protection.Though and the latter uses clean solar, at solar irradiations such as cloudy day, winter, nights more weak or do not have solar irradiation in, can not water be heated to suitable temperature.At present, the cooking stove when people cook, the utilization rate of its heat is relatively low, and more thermal energy directly enters among the atmosphere with the form of flue gas, and neither environmental protection wastes energy again.
The utility model content
The purpose of the utility model is and a kind of flue gas waste heat recovery apparatus is provided, and can make full use of the heat energy of flue gas, and water is heated, and supplies daily use.
For achieving the above object; The technical scheme of the utility model is: flue gas waste heat recovery apparatus, comprise the spirality heat exchanger tube that places in the flue, and said spirality heat exchanger tube has comprised water inlet and delivery port; Said water inlet is positioned at the lower end of spirality heat exchanger tube; Said delivery port is positioned at the upper end of spirality heat exchanger tube, and said water inlet is connected with water-storing device through pipeline, and the horizontal level of said water-storing device is higher than the horizontal level of the delivery port of spirality heat exchanger tube.
When adopting technique scheme; The utility model flue gas waste heat recovery apparatus; In flue, insert a spirality heat exchanger tube, the passage the when space that surrounds between wherein is the cooking stove smoke evacuation is when flue gas gets into this passage; Produce heat exchange with the spirality heat exchanger tube, the water in the spirality heat exchanger tube is heated.Moreover; The spirality heat exchanger tube has comprised water inlet and delivery port; Said water inlet is positioned at the lower end of spirality heat exchanger tube; Said delivery port is positioned at the upper end of spirality heat exchanger tube, and said water inlet is connected with water-storing device through pipeline, and the horizontal level of said water-storing device is higher than the horizontal level of the delivery port of spirality heat exchanger tube.After the spirality heat exchanger tube had absorbed great amount of heat energy, the water in it heated up, and forms convection current through the water in pipeline and the water-storing device, thereby the water in the water-storing device is heated.The utility model is simple in structure, enforcement is easy, and environmental protection and energy saving are being guaranteed under the situation of the additive decrementation energy not, utilize the waste heat heating.This design simultaneously also can be solar water heater, electric heater etc. a kind of assistant heating facility, especially solar water heater is provided, and all can heat for it at cloudy day, winter and night.Not only utilize cooking stove fume afterheat heating domestic water, energy-conserving and environment-protective also can be other water heater simultaneously assistant heating are provided.
Further, water-storing device is a heat-preservation cylinder.Utilize heat-preservation cylinder to store, can play the effect of thermal isolation and heat storage, waste heat that can the more efficient use flue gas through the water after the heating of spirality heat exchanger tube.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model flue gas waste heat recovery apparatus embodiment.
The specific embodiment
The utility model flue gas waste heat recovery apparatus; Comprise the spirality heat exchanger tube 1 that places in the flue; Said spirality heat exchanger tube 1 has comprised water inlet 2 and delivery port 3, and said water inlet 2 is positioned at the lower end of spirality heat exchanger tube 1, and said delivery port 3 is positioned at the upper end of spirality heat exchanger tube 1; Said water inlet 2 is connected with heat-preserving container 4 through pipeline, and the horizontal level of said heat-preserving container 4 is higher than the horizontal level of the delivery port of spirality heat exchanger tube.
The utility model flue gas waste heat recovery apparatus; In flue, insert a spirality heat exchanger tube 1, the passage the when space that surrounds between wherein is the cooking stove smoke evacuation is when flue gas gets into this passage; Produce heat exchange with spirality heat exchanger tube 1, the water in the spirality heat exchanger tube 1 is heated.Moreover; Spirality heat exchanger tube 1 has comprised water inlet 2 and delivery port 3; Said water inlet 2 is positioned at the lower end of spirality heat exchanger tube 1; Said delivery port 3 is positioned at the upper end of spirality heat exchanger tube 1, and said water inlet 2 is connected with heat-preserving container 4 through pipeline, and the horizontal level of said heat-preserving container 4 is higher than the horizontal level of the delivery port 3 of spirality heat exchanger tube 1.After spirality heat exchanger tube 1 had absorbed great amount of heat energy, the water in it heated up, and forms convection current through the water in pipeline and the heat-preserving container 4, thereby the water in the heat-preserving container 4 is heated.The utility model is simple in structure, enforcement is easy, and environmental protection and energy saving are being guaranteed under the situation of the additive decrementation energy not, utilize the waste heat heating.This design simultaneously also can be solar water heater, electric heater etc. a kind of assistant heating facility, especially solar water heater is provided, and all can heat for it at cloudy day, winter and night.Not only utilize cooking stove fume afterheat heating domestic water, energy-conserving and environment-protective also can be other water heater simultaneously assistant heating are provided.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some modification and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
