Background

The carbon roasting furnace is one of main equipment for producing carbon products, asphalt smoke generated by the carbon roasting furnace cannot be avoided, and the asphalt smoke needs to be electrically captured by an electrical tar capturing device. As shown in fig. 1, the conventional flue gas treatment system for a carbon roasting furnace includes an electrical tar precipitator 2, a roasting furnace 1 and a chimney 3 respectively connected to the electrical tar precipitator 2. The electrical tar precipitator 2 is arranged at a smoke exhaust outlet (not shown) of the roasting furnace 1, an outlet of the electrical tar precipitator 2 is connected with a chimney, the electrical tar precipitator 2 can electrically precipitate insufficiently-combusted asphalt in the roasting furnace 1, and the electrically-precipitated asphalt is conveyed to a container through a feed opening 21 to be collected.

Normally, the electric tar precipitator has a small amount of pitch electrically captured, but when the roasting furnace is used for a long time, the electric tar precipitator can electrically capture a large amount of pitch, which is mainly caused by insufficient combustion in the furnace chamber of the roasting furnace. After the furnace chamber burns for a long time, the flame path wall in the furnace chamber is over-burnt seriously, which can cause the deformation of the flame path wall; the volatilization and combustion in the furnace are insufficient, and the captured asphalt components do not reach the standard and cannot be used for the second time, so that a large amount of solid waste asphalt is stored for a long time, and the environmental protection pressure is great for the surrounding environment.

Detailed Description

The following non-limiting detailed description of the present invention is provided in connection with the preferred embodiments and accompanying drawings.

As shown in fig. 2, the present example provides a carbon baking furnace 1 capable of reusing pitch electrically captured by an electrical tar precipitator.

The roasting furnace 1 comprises a plurality of furnace chambers 4 communicated with each other, and each furnace chamber 4 comprises a furnace wall 5, a back fire wall 6 and a fire well 7. The furnace walls 5 are arranged outside the furnace chambers 4, and two adjacent furnace chambers 4 are connected through the furnace walls 5. A horizontal passage 41 communicating the two furnace chambers 4 and a vertical passage 42 communicating with the horizontal passage 41 and vertically provided are provided in the furnace wall 5. The anti-fire wall 6 sets up in furnace chamber 4, anti-fire wall 6 includes first anti-fire wall 61, second anti-fire wall 62 and third anti-fire wall 63, it is first, second anti-fire wall 61,62 down extend from last in furnace chamber 4 top, third anti-fire wall 63 is from furnace chamber 4 bottom down up extending, third anti-fire wall 63 is located first, between second anti-fire wall 61,62, make the interior similar sinusoidal flame path 8 that forms of furnace chamber 4, flame path 8 makes the interior heating of furnace chamber 4 more even, the flue gas walking is smooth. The fire well 7 comprises a fire well mouth 71 communicated with the fire well mouth 71, the fire well mouth 71 is positioned above the furnace chamber 4, and a well mouth cover 72 is arranged on the fire well mouth 71, so that air cannot be sucked from the fire well mouth 71 when exhaust gas emission is needed.
