Embodiment Construction

[0026] Such as figure 1 , figure 2 , image 3 with Figure 4 Shown: A method for energy saving and emission reduction of carbon anode baking furnace, the specific methods and measures are as follows:

[0027] 1) Roaster sealing

[0028] 1-1. First, we confirm the length and width of the furnace cover according to the length and width of each furnace chamber of the roasting furnace, and confirm the height of the furnace cover according to the heat dissipation temperature of the furnace surface of the high temperature furnace chamber to obtain the furnace cover length, width and height. size of;

[0029] 1-2. Make a special furnace surface seal furnace cover according to the furnace cover size, use several channel steels 1 to fix the screen 2 on the furnace cover frame 3, and place the flame retardant cloth 4 on the fixing frame 5 at the bottom of the furnace cover frame 3. And fixed by the pressure rod 6 on the side of the furnace cover frame 3, the fiber felt 9 is arranged between...

Abstract

The invention provides an energy saving and emission reduction method of a carbon anode baking furnace, and relates to the field of metallurgical industry carbon techniques. A special furnace face sealing furnace cover is specially configured for the baking furnace, and the process of the baking furnace is optimized, namely the flame jetting length is 0.35 time of the flame path depth, the difference between temperature of products in a preheating furnace chamber and flame path smoke temperature is more than 280 DEG C, and a thermocouple is inserted into a second feed box of the preheating furnace chamber. According to the method, the sealing effect of the baking furnace is greatly improved, and cold air is effectively prevented from entering the baking furnace; meanwhile according to the practical experience of temperature distribution in the furnace chamber, the operation technique of the baking furnace is optimized, it is guaranteed that volatile matter fully burns and temperature on the upper portion of a flame path and temperature on the lower portion of the flame path are uniform, and energy consumption of the carbon anode baking furnace is greatly reduced.

Description

Technical field [0001] The invention relates to the technical field of carbon in the metallurgical industry, in particular to an energy-saving and emission-reduction method for a carbon anode baking furnace. Background technique [0002] my country is a major producer of electrolytic aluminum industry. With the substantial growth of electrolytic aluminum, the demand for anode carbon blocks is also increasing day by day. In the process of aluminum carbon anode production, the roasting furnace is a very important equipment. Investment accounts for 40% of the investment in the carbon anode factory, which has the greatest impact on the investment in the construction of the factory and the production cost. The energy consumption of the roasting process accounts for more than 50% of the energy consumption of the carbon anode production. Since the roasting furnace has a very poor sealing effect after 2-3 years of operation, cold air enters the combustion channel, which increases fuel co...
