Embodiment 1

[0017] Such as figure 2 As shown, the bagasse 8 is placed upside down in the kiln body 4 to the middle of the kiln body to stop dumping, the ignition point 3 is ignited in the middle of the kiln body, the induced draft fan is turned on, and the airflow 9 passes through the sky above the ground, the interior of the kiln body 4, and the kiln bottom brick 5. The air gap between the supporting bricks, the channel between the supporting bricks 6, the air duct 7 to the induced draft fan; after that, the bagasse 8 is continuously poured into the kiln body until it is flush with the ground. The carbonization kiln of the present invention starts the carbonization work, and after the carbonization is completed, the upper layer of uncarbonized bagasse is removed, and the carbonized bagasse is taken out.

Embodiment 2

[0019] Such as figure 2 As shown, put the furfural slag upside down in the kiln body 4 to the middle of the kiln body and stop dumping, ignite the ignition point 3 in the middle of the kiln body, turn on the induced draft fan, and the airflow 9 passes through the sky above the ground, inside the kiln body 4, and between the kiln bottom bricks 5 The air gap between the supporting bricks, the channel between the supporting bricks 6, the air duct 7 to the induced draft fan; after that, the furfural slag is continuously poured into the kiln body until it is flush with the ground. The carbonization kiln of the present invention starts the carbonization work, and after the carbonization is completed, the upper layer of uncarbonized furfural slag is removed, and the carbonized furfural slag is taken out.

Embodiment 3

[0021] Such as figure 2 As shown, put the xylose slag upside down in the kiln body 4 to the middle of the kiln body and stop dumping, light the ignition point 3 in the middle of the kiln body, turn on the induced draft fan, and the airflow 9 passes through the sky above the ground, the inside of the kiln body 4, and the kiln bottom brick 5 The ventilation gap between the supporting bricks, the channel between the supporting bricks 6, the air duct 7 to the induced draft fan; after that, the xylose slag will continue to be poured into the kiln body until it is flush with the ground. The carbonization kiln of the present invention starts the carbonization work, and after the carbonization is completed, removes the uncarbonized xylose residue in the upper layer, and takes out the carbonized xylose residue.

Abstract

The invention discloses a carbonizing kiln for charring wet or dry fibrous residues containing carbon. The carbonizing kiln comprises kiln walls (1) and a kiln body (4) defined by the kiln walls (1); the kiln walls (1) of the kiln body (4) are embedded in an earth body (2); the upper part of the kiln body (4) is exposed to air; the bottom of the kiln body (4) is floored by a plurality of kiln bottom refractory bricks (5) laid side by side in a single layer; the bottoms of the kiln bottom refractory bricks (5) are supported by a plurality of supporting refractory bricks (6); one side out of the kiln walls (1) is provided with an air channel (7) which connects air above ground with passages between the supporting refractory bricks (6) at the lower part of the kiln bottom; an induced draft fan is connected at the exit of the air channel (7) in the ground. According to the invention, air flow of the carbonizing kiln is designed to be the type of down-draught and the flowing of the air flow is uniformly distributed at the bottom of the carbonizing kiln; therefore, a good charring effect is obtained and direct carbonization of wet fibrous residues containing carbon is realized, thereby removing the step of drying before carbonization, reducing energy consumption of carbonization and achieving a better charring effect.

Description

technical field [0001] The invention relates to a carbonization kiln, in particular to a carbonization kiln for carbonizing wet or dry carbon fiber-containing waste residue. Background technique [0002] In the carbonization process of the carbonization kiln or carbonization furnace, it first needs to go through the raw material drying process, that is, the material to be carbonized is dried, and then heated and dehydrated by isolating the air to complete the carbonization process. Therefore, at present, the kiln body can only carbonize dry carbon-containing fiber waste residues, such as sawdust, and for wet carbon-containing fiber waste residues such as furfural residue, sugarcane bagasse and xylose residue, according to the existing technical conditions, it must be dried before entering The carbonization kiln carries out carbonization, and its production process is complex, and the production cost is high, and it is also not conducive to the recycling of wet carbon fiber-c...
