Device for utilizing waste heat of tobacco microwave processing equipment

The utility model relates to a device for utilizing waste heat of tobacco microwave processing equipment. The device comprises microwave heating equipment and tobacco processing equipment for processing tobacco by utilizing hot wind and is characterized in that a hot wind conveying pipeline is connected between an exhaust duct of a cooling system of the microwave heating equipment and a hot wind inlet of the tobacco processing equipment; the hot wind exhausted by the microwave processing equipment is inducted into the tobacco processing equipment; and a fresh wind pipeline and a wind quantity regulating valve are connected on the hot wind conveying pipeline. The device for utilizing the waste heat of the tobacco microwave processing equipment has the advantages that 1, the waste heat generated by a magnetron cooling system of the microwave tobacco heating equipment is effectively utilized and the utilization rate of energy of the tobacco microwave processing equipment is improved; 2, the fresh wind inlet quantity of the tobacco processing equipment for processing the tobacco by the hot wind is reduced so as to reduce the influence on the temperature and the humidity of a tobacco processing workshop and reduce the energy consumption of an air conditioner in the tobacco processing workshop; and 3, a wind temperature of the hot wind exhausted by the cooling system can be ensured to be constant at a temperature of about 70 DEG C by a fan frequency converter so as to reduce the exhaust air rate of the ventilating cooling system of the tobacco microwave processing equipment and reduce the energy consumption of the equipment.
