The carbonization furnace is generally based on resistance heating. By energizing the heating element to make it heat up, high temperature is generated to form a closed thermal field, and thermal radiation is performed on the material in the thermal field, so as to achieve the purpose of temperature change of the material, and finally the material undergoes a chemical reaction to form carbonization. During the process, the temperature rises to 400-1400℃, the moisture in the material is first extracted, and the shrinkage and decoking stages are performed simultaneously during the process.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1-3As shown, a carbonization furnace decoking device includes a carbonization furnace, wherein the carbonization furnace 1 is connected to a first condensation bin 2 and a second condensation bin 3 by two pipes, the first condensation bin 2 and the second condensation bin 3 are arranged in parallel through pipes and are provided with placement cavities inside, and honeycomb condensers 15 are placed in the placement cavities, the first condensation bin 2 and the second condensation bin 3 are connected by pipes to the first heat exchanger 4 and the second heat exchanger 5 arranged in series, the first heat exchanger 4 and the second heat exchanger 5 are provided with cavities inside, and a heat exchanger 12 is placed in the cavity, the other end of the second heat exchanger 5 is connected to the pipe between the first filter element 7 and the second filter element 8, the other end of the first filter element 7 is connected to the first vacuum pump 6, and the other end of the second filter element 8 is connected to the second vacuum pump 9.

[0017] Among them, when the material is carbonized at high temperature in the carbonization furnace 1, the emitted tar enters the first condensation bin 2 and the second condensation bin 3 through the pipeline. When the tar passes through the honeycomb condenser 15 in the first condensation bin 2 and the second condensation bin 3, due to the cooling water channel inside the honeycomb condenser 15, the tar is cooled and adsorbed and condensed in the honeycomb condenser 15. The uncondensed tar enters the first heat exchanger 4 and the second heat exchanger 5, and is further cooled by the heat exchanger 12 inside the first heat exchanger 4 and the second heat exchanger 5. The tar is condensed and collected, and finally discharged through the filter element.

[0018] like Figure 3 As shown, the honeycomb condenser 15 is cylindrical and has a through hole. An irregular cooling water channel is arranged inside the honeycomb condenser 15. The cooling water channel is not connected to the through hole. At least two condensation bin water pipes 13 are fixed at the inlet, and the outlet is connected to the water outlet at the bottom of the condensation bin. A condenser positioning plate 14 is fixed on the top of the condensation bin water pipe 13.

[0019] Among them, the through holes are designed to allow the tar to pass through unimpeded and be cooled and adsorbed while passing through. Multiple through holes can ensure the smooth passage of tar. The cooling water channel can cool the tar without contacting the tar. After the tar is adsorbed to a certain extent, it can be lifted out by the handle.

[0020] like Figure 3 As shown, the condensing bin water pipe 13 is made of a metal hollow tube, and the side wall of the condenser positioning plate 14 is provided with a plurality of U-shaped notches.

[0021] The U-shaped notch is used to fix the condenser positioning plate 14 on the condensing chamber to prevent it from being loosened and moved.

[0022] like Figure 2As shown, the upper and lower ends of the heat exchanger 12 are respectively provided with upper and lower fixed plates, cooling water channels are provided in the upper and lower fixed plates, and a number of hollow metal tubes distributed around are fixed between the upper and lower fixed plates, the hollow metal tubes are all connected to the cooling water channels, and a number of heat sinks are fixed on the outer tube wall.

[0023] Among them, the function of the heat exchanger 12 is to further cool and collect the tar. The tar that has been initially collected enters the heat exchanger. The hollow metal tubes in the heat exchanger 12 are filled with cooling water. The tar passes through and is cooled and adsorbed on the heat sink of the outer wall of the hollow metal tube.

[0024] like Figure 2 As shown, a heat exchanger positioning plate 11 is fixed on the upper plane of the upper fixed plate, a heat exchanger water inlet 10 is fixed on the heat exchanger positioning plate 11, and the heat exchanger water inlet 10 is connected to the cooling water channel in the upper fixed plate. The lower fixed plate is provided with a water outlet connected to the water outlet pipe at the bottom of the heat exchanger.

[0025] Among them, the water inlet and the water outlet are set to circulate the cooling water to prevent the problem that the cooling water cannot cool after a certain period of time.
