Description

Technical Field

[0001] The invention relates to an energy-saving carbonization furnace, in particular to an energy-saving carbonization furnace with high-position discharge. Background Art

[0002] The discharge ports of the existing disclosed patents, rotary carbonization furnace (publication number: CN109337696A) and a rotary carbonization furnace (publication number: CN105038821B) are all bottom discharge ports. The principle of the bottom discharge of carbonized material is that the carbonized material is transported to the discharge port at the tail of the carbonization furnace under the action of the rotation of the carbonization furnace body and gravity. During the rotation of the furnace body, the carbonized material flows from the bottom of the furnace port to the discharge port under the action of gravity and the folding plate, and the carbonized material comes out from the bottom discharge port.

[0003] In the activated carbon production process, the carbonized material needs to be transported to the slag cooler after coming out of the carbonization furnace. Therefore, after the carbonized material comes out of the discharge pipe, the carbonized material is added to the slag cooler by a hoist. In addition, the carbonized material enters the storage pool after being discharged from the lower port, and is easily broken under the action of gravity, and cannot be activated in subsequent processes.

[0004] In the process of transporting the lower discharge port to the upper high-position slag cooler in the prior art, the dust raising point of the carbonized material is increased, and additional carbonized material lifting and transportation equipment is required. Summary of the invention

[0005] The high-position discharge carbonization furnace of the present invention overcomes the dust raising point in the prior art during the lifting and transportation of carbonized materials, saves transportation and lifting equipment for carbonized materials, and improves the transportation efficiency of carbonized materials.

[0006] The technical effects of the present invention are achieved through the following technical solutions.

[0007] A high-level discharge carbonization furnace comprises a furnace body of the carbonization furnace, a feed port at one end of the furnace body, a heating chamber surrounding the furnace body of carbonized material, a combustion smoke inlet at the bottom of the heating chamber, a combustion smoke outlet at the top of the heating chamber, refractory bricks on the inner wall of the furnace body, a carbonization cavity formed by the refractory bricks of the carbonization furnace, a supporting wheel device of the furnace body of the carbonization furnace, a motor for driving the supporting wheel device to rotate, and a discharge system installed at the tail of the carbonization furnace, the discharge system comprising a furnace mouth, a discharge pipe at the bottom of the furnace mouth, a folding plate in the furnace mouth, an arc hopper arranged outside the furnace mouth and connected to the discharge pipe for holding carbonized material, and a rotating motor for driving the arc hopper to rotate from the bottom to the top. The high-position discharging carbonization furnace of the present invention has a folding plate inside the discharging furnace port, and the carbonized material is folded into the arc hopper through the discharging pipe. The arc hopper rotates to the high position of the furnace port to pour out the carbonized material. After the carbonized material is poured out, the arc hopper rotates again to the bottom of the furnace port for cyclic rotation. The arc hopper rotates to the lower end, and the carbonized material enters the arc hopper. The arc hopper rotates again to the high position of the furnace port to pour out the carbonized material.

[0008] Further, the heating chamber is a gas heating chamber or a solid heating chamber.

[0009] Furthermore, the heating chamber is an integrated heating chamber or a segmented heating chamber.

[0010] Furthermore, the refractory bricks are high-alumina refractory bricks or clay refractory bricks.

[0011] Furthermore, the number of the folding plates is four, and the folding plates are evenly distributed on the circumference of the furnace mouth.

[0012] Furthermore, the hopper is a stainless steel hopper. The temperature of the carbonized material is above 650°C, and a hopper made of ordinary materials will deform and leak, so it must be made of stainless steel.

[0013] Furthermore, the rotation direction of the furnace body is counterclockwise.

[0014] The high-discharge energy-saving carbonization furnace of the present invention has an arc-shaped hopper installed at the discharge pipe of the carbonized material, which lifts the carbonized material from the lower part of the furnace mouth to the higher part of the furnace mouth and then pours the carbonized material out. The high-discharge energy-saving carbonization furnace of the present invention can directly pour the carbonized material from the arc-shaped hopper into the slag cooler.

[0015] Compared with the prior art, the high-position discharging carbonization furnace of the present invention reduces the operation procedure of the high-position feeding from the low position to the next process after the carbonized material is discharged from the furnace, reduces the dust raising probability of the carbonized material, and avoids the technical defect that the carbonized material is broken when it is discharged from the lower part and enters the storage tank. The prior art requires the carbonized material to be horizontally drawn out from the discharge port at the bottom of the furnace body, and then a hoist is installed to lift the carbonized material to a high position. Compared with the prior art, the high-position discharging carbonization furnace of the present invention saves the need to add an additional carbonization furnace hoist and an operating equipment to pull the carbonized material out of the discharge port outside the prior art.

The arc hopper 10-4 rotates counterclockwise with the furnace body 1 to the high position of the furnace mouth 10-1, and pours the carbonized material from the discharge port 10-5 of the arc hopper 10-4. After the carbonized material is poured out, the arc hopper 10-4 continues to rotate at the lower part with the furnace body, and the carbonized material enters the arc hopper 10-4 from the discharge pipe 10-2, and the cycle works.
