Novel trolley type carbon roasting furnace system adopting pitch smoke heating

Abstract

The invention relates to a novel trolley type carbon roasting furnace system adopting pitch smoke heating. Pitch smoke generated in roasting procedures serves as a heat source and is used for heating carbon products in a trolley type carbon roasting furnace. Under the normal production condition, the consumption of natural gas can be omitted. In addition, at the whole roasting stage, no open flame exists in the trolley type carbon roasting furnace of the system, the open flame element in three explosion elements is separated, and even when the condition of excessive combustion-supporting air (excessive oxygen content) exists, the safety accident that the trolley type carbon roasting furnace explodes cannot be caused to the trolley type carbon roasting furnace of the system; At the whole roasting stage, the roasting procedure I and the roasting procedure II are involved, the atmosphere in the trolley type carbon roasting furnace is strictly controlled at the temperature rise stage and the temperature drop stage, and safety is higher. The system can efficiently recycle waste heat of the trolley type carbon roasting furnace, and is more economical and capable of saving more energy.

Description

technical field [0001] The invention relates to the technical field of carbon product roasting furnaces, in particular to a novel trolley-type carbon roasting furnace system heated by asphalt flue gas. Background technique [0002] Domestic carbon roasting furnaces are currently mainly ring furnaces. Due to the large temperature difference in the furnace chamber of the ring furnace (the temperature difference in the furnace chamber is 200°C-300°C), the mutual influence of adjacent furnace chambers, and the long cycle of the roasting process, the ring furnace began to be neglected. The eyes of domestic carbon enterprises have already aimed at the trolley-type carbon roasting furnaces commonly used by foreign advanced carbon enterprises. [0003] The import price of trolley-type carbon roasting furnace is as high as RMB 20 million or more each. Due to its high price, few domestic carbon companies care about it. [0004] The trolley-type carbon roasting furnaces commonly use...
