Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in the figure, the air heat energy recovery device comprises an air conveying pipe 1 and an exhaust gas conveying pipe 2 which are arranged in parallel at the left side and the right side and are of a cuboid structure, wherein a hot exhaust gas inlet 201 and a cooling exhaust gas outlet 202 are respectively arranged at two ends of the exhaust gas conveying pipe 2, an air inlet 101 and a hot air outlet 102 are respectively arranged at two ends of the air conveying pipe 1, the directions of the air inlet 101 and the hot exhaust gas inlet 201 are opposite, the hot exhaust gas inlet 201 is used for introducing collected hot exhaust gas as a heating body, the air inlet is used for introducing air to be cooled as a heated body, the hot exhaust gas can be heat energy exhaust gas generated by heating and fermenting kitchen and fruit and vegetable waste, and the heated air can be used as new air to be heated and fermented, so that the heating energy consumption. In order to better achieve the effect of heat conversion, heat conduction oil is used as a heat section body, heat conduction oil interlayers 3 are arranged above and below the air conveying pipe 1 and the waste gas conveying pipe 2, the upper heat conduction oil interlayer 3 and the lower heat conduction oil interlayer 3 are communicated through a vertical fin pipe 4, and heat conduction oil 6 is injected into a heat conduction oil pipe 301 arranged through the heat conduction oil interlayer 3 above.
When the device is in operation, the hot waste gas in the waste gas conveying pipe 2 firstly transfers heat energy to the heat conduction oil 6, the heat conduction oil 6 is heated, and the hot waste gas is changed into cooling waste gas; the heat conducting oil 6 heated in the air conveying pipe transfers heat energy to low-temperature air, the heat conducting oil 6 is cooled, and the air is changed into hot air. Therefore, the heat conduction oil 6 is used as the heat receiver, the air quantity is large, the heat capacity is small, if the traditional fin is used as the heat conductor, the heat energy interacted in a short time is small, the heat conduction oil 6 has large heat capacity relative to the air and is easy to dissipate heat, a small amount of heat conduction oil 6 can store the heat energy of large-volume hot waste gas, so that more heat energy can be absorbed, the temperature of the discharged cooling waste gas can be reduced by a lot, and the temperature of the conveyed hot air can be improved by a lot through the heat exchange between the heat conduction oil 6 and the air.
