The invention relates to the technical field of range hoods, and discloses flue gas energy recycling equipment for a range hood. The flue gas energy recycling equipment comprises a flue gas pipeline,a drain outlet is formed in the inner bottom of the flue gas pipeline, a heat collection water tank is arranged above the flue gas pipeline, heat exchange pipes are arranged inside the flue gas pipeline and are located above the drain outlet, the top ends of the heat exchange pipes penetrate through the flue gas pipeline and extend into the heat collection water tank, and the heat exchange pipes are filled with a heat exchange medium capable of being gasified after being heated. According to the flue gas energy recycling equipment, the heat exchange pipes are filled with the heat exchange medium, the heat exchange medium is subjected to heat exchange and gasification through oil fume in the flue gas pipeline and then is liquefied to release heat above the heat exchange pipes, water in theheat collection water tank is heated, the liquefied heat exchange medium then falls into the inner bottoms of the heat exchange pipes, so that the recovery of waste heat of flue gas is completed, meanwhile, the equipment can complete the heat exchange process without any additional power devices, in addition, the influence of the flow resistance of the flue gas in the flue gas pipeline is almost negligible, and condensed oil stains can be discharged from the drain outlet, and cleaning is facilitated.
Description
technical field [0001] The invention relates to the technical field of range hoods, in particular to equipment for recovering and utilizing flue gas energy of range hoods. Background technique [0002] The range hood is used to exhaust the oily fume generated by the stove in the kitchen to the outside. Most of the range hoods in the current market directly exhaust the oil fume to the outside. Since the initial temperature of the oil fume is above 200°C, the oil fume discharged outside is still above 80°C, and this part of the heat dissipates into the surrounding environment, causing pollution. The ambient temperature rises. [0003] It is also proposed to recover and utilize the waste heat in the oil fume, such as using a heat pump to recycle heat, and using a thermoelectric power generation sheet to recover waste heat for power generation. However, both circulating water and heat pumps need to use additional motor equipment, which consumes electric energy, and the heat re...
