Cigarette cooling and waste heat secondary utilization device:
Smoke temperature cooling process: The device is installed by the exhaust port of the chimney. The device is separated from the heating crucible. After the construction is detachable, the flue gas enters the cooling tube bundle in the cooling device, and the cooling tube bundle passes through the cooling liquid in the interlayer ( Water. Seawater) absorbs heat. The circulating water can achieve the purpose of cooling at 3 cubic meters per hour. The displacement of the pump can be adjusted according to the change of the temperature of the smoke to reduce the temperature of the smoke and improve the heat exchange efficiency. It consists of a heat exchanger, a heat collecting port, a heat release port, a concentrating energy converter, and a heating supercatheter.
