Problems solved by technology
No matter what kind of technology, its disadvantage is that no matter where the air in the preheating air channel is directed to support combustion, its flow rate must be adjusted by the tank calciner as a whole, so that its flow rate cannot be raised very high, but rather low The high flow rate makes its cooling effect limited, which on the one hand reduces the service life of the cooling water jacket, and on the other hand indirectly causes the discharge temperature of petroleum coke to remain high

The invention discloses a pot calciner system. The pot calciner system comprises a calciner body. The calciner body comprises a calcination chamber, and multiple layers of flame paths arranged outsidethe calcination chamber. The calciner body is further in sliding connection with an adjustment pull plate. The calcination chamber comprises a feeding inlet, a cavity and a discharging outlet in sequence from top to bottom. The discharging outlet is provided with a cooling water jacket. Multiple preheating air channels are further arranged between the flame path on the bottom layer and the cooling water jacket. The pot calciner system further comprises a collection pipe, a draught fan, a heat exchange boiler, a heat exchange pump and a heat using apparatus. The preheating air channels are allconnected to the collection pipe. The collection pipe is connected with the heat exchange boiler and the draught fan in sequence. The heat exchange boiler, the heat exchange pump and the heat using apparatus are connected in sequence through a circulating pipe to form a heat exchange loop. The collection pipe and the circulating pipe carry out heat exchange in the heat exchange boiler. Accordingto the pot calciner system, the velocity of the air in the preheating air channels is not controlled by calcination, the heat exchange efficiency is improved through high-velocity wind current, and the bulk temperature of the area where the high-velocity wind current is in is lowered.
Description
technical field [0001] The invention relates to chemical equipment, in particular to a tank type calciner system. Background technique [0002] Due to the advantages of long heating time, sufficient heating, and less carbon loss, the tank-type calciner is currently the mainstream petroleum coke calcination equipment in my country. Carry out indirect high-temperature calcination. [0003] In the existing technology, the maximum calcination temperature of petroleum coke is generally between 1200-1300 degrees Celsius, while the discharge temperature of the final product is about 100 degrees Celsius, that is, from feeding to discharging, petroleum coke needs to undergo a rapid temperature rise to nearly 1300 Celsius and rapid cooling to 100 degrees. In the cooling stage, the existing technology realizes rapid cooling by setting a cooling water jacket on the discharge port. However, the temperature of the bottom fire path still has a temperature between 900-1150 degrees Celsius. ...
