Detailed Description
The following describes the technical solutions in the embodiments of the present application in detail with reference to the drawings in the embodiments of the present application.
The inventors of the present application have found that pyrolysis is commonly used in the industry for the recovery of fiber composites. And no special carbon removing equipment is provided for residual carbon attached to the fibers after the pyrolysis reaction. The existing carbon removal operation is usually completed in a pyrolysis furnace, namely, after the pyrolysis reaction of the fiber composite material is completed, the carbon removal operation is continued. Thus, the cycle of pyrolysis and carbon removal is overlong every time, the improvement of production capacity is greatly limited, and continuous carbon removal cannot be realized.
In view of this, the application provides a conveyor belt type decarbonization furnace, which is independent of a pyrolysis furnace and can be used for carrying out decarbonization operation on a fiber composite material subjected to pyrolysis reaction in a large-scale, continuous, low-cost and low-energy consumption manner.
Implementation mode one
A first embodiment of the present application proposes a conveyor belt type decarbonizing furnace, which, as shown in combination with fig. 1 and 2, includes:
the furnace comprises a furnace body 1 and a conveyor belt device 2 which penetrates through the furnace body 1;
the temperature control device is connected into the furnace body 1 and adjusts the temperature of the furnace body 1;
the oxidizing gas conveying device comprises a plurality of gas conveying pipelines 3 connected into the furnace body 1 and used for introducing oxidizing gas into the furnace body 1;
and the air extracting device is arranged at the top of the furnace body 1 and is used for extracting the gas in the furnace body 1, and the air extracting device enables the interior of the furnace body 1 to be kept in a negative pressure state.
The furnace body 1 in the application is used as a frame structure of the conveyor belt type carbon removing furnace, and on one hand, mounting positions are provided for all parts; on the other hand, the device also serves as a space required by the carbon removal operation, is isolated from the outside, and provides an independent operation space for the carbon removal operation so as to ensure the carbon removal operation to be carried out smoothly. In the embodiment of the present application, the furnace body 1 may be configured as a horizontal structure, and the bottom is provided with various supporting members for supporting the furnace body 1, such as various supporting beams, supporting pillars, and the like. In addition, furnace body 1 in this application can avoid inside heat to run off by outside parcel insulation material, reduces the energy loss, can also completely cut off inside heat, avoids leading to the staff to scald because of unexpected touching.
And the transmission belt device is used for conveying the fiber composite material to be subjected to the decarbonization treatment, enters the furnace body 1 from one side of the furnace body 1, extends out from the other side of the furnace body, and then circularly rotates to the entering side to realize continuous feeding. In the process of conveying the fiber composite material, the residual carbon on the fiber composite material in the furnace body 1 is subjected to oxidation reaction, so that the carbon removal operation is realized. The time required for carbon removal may also vary for different types of fiber composites. Therefore, in the actual production process, a person skilled in the art can control the conveyor belt device 2 according to the type of the fiber composite material to be decarburized so as to adjust the moving speed of the fiber composite material, and further control the decarburizing time of the fiber composite material to ensure complete decarburizing.
In the present application, the gas supply duct 3 is used for introducing an oxidizing gas into the furnace body 1. The fiber composite material is flushed by the oxidizing gas at a certain temperature, so that the aim of removing carbon can be fulfilled while an oxidation reaction is generated. Specifically, in the present embodiment, the plurality of air supply ducts 3 are provided inside the furnace body 1 and can be uniformly distributed in the conveying direction of the conveyor belt device 2. The fiber composite material passes through the spraying areas corresponding to the plurality of gas supply pipelines 3 in sequence in the process of being driven and conveyed by the conveyor belt device 2, and is washed by the oxidizing gas sprayed by the gas supply pipelines 3 corresponding to the areas.
The air extracting device is used for extracting the air in the furnace body 1 to keep the interior of the furnace body 1 in a negative pressure state. The gas includes an oxidizing gas ejected from the gas supply pipe 3 and a gas generated by a reaction of the fiber composite material. After the carbon residue on the surface of the fiber composite material is contacted with the oxidizing gas, oxidation reaction can be carried out to generate carbon dioxide. Therefore, by providing the gas extraction device, the residual carbon filled in the inner space of the furnace body 1 can be collected as carbon dioxide while extracting the gas in the furnace body 1. Moreover, because the interior of the furnace body 1 is kept in a negative pressure state, the gas filled in the inner space of the furnace body 1 cannot leak out of the furnace body 1 under the action of air pressure, and the furnace body is beneficial to keeping the cleanness of the external working environment.
The existing carbon removing equipment is usually heated in an electric heating mode. However, in this way, heat is generally transferred by heat radiation of the heating wires or contact between materials, which tends to cause temperature unevenness in various regions in the furnace body 1. In the present embodiment, the fiber composite material is heated by the gas, so that the reaction temperature can be more uniform. Specifically, the oxidizing gas in this embodiment may be high-compressed air at 400 ℃ to 500 ℃. By arranging the air supply pipeline 3, high-compressed air is introduced into the furnace body 1 through the air supply pipeline 3 to heat the fiber composite material. Compared with electric heating, the high-temperature gas heating has the advantage of better diffusivity. The oxidizing gas directly contacts with the fiber composite materials and diffuses through gaps among the fiber composite materials, the heating effect is good, and the heat transfer is fast.
In addition, in this embodiment, the advantages of using high-pressure compressed air for heating and carbon removal are: the preparation of high compressed air is simple, and the pyrolysis gas that produces when can utilizing pyrolysis fiber composite burns the heated air and prepares, and the energy can be retrieved and recycled, can realize cleaner production.
The conveyor belt type carbon removing furnace can also comprise a temperature control device which is connected into the furnace body 1 and adjusts the temperature of the furnace body 1. On the basis that high compressed air is used as a main heat source of the furnace body 1, the temperature control device can be used as an auxiliary heat source to perform auxiliary heating on the furnace body 1 so as to adjust the local temperature of the furnace body 1, prevent the problem of uneven local temperature of dead corners of gas diffusion and further improve the heating uniformity.
The conveyer belt type decarbonization furnace in the application conveys the fiber composite material through the conveyer belt device 2, and in the conveying process of the conveyer belt, the oxidizing gas sprayed out by the gas supply pipeline 3 is utilized to oxidize the residual carbon in the fiber composite material, so that the decarbonization operation can be carried out on the fiber composite material finished by the pyrolysis reaction in a large-scale, continuous, low-cost and low-energy-consumption manner, and the conveyer belt type decarbonization furnace has a good decarbonization effect.
Second embodiment
The implementation mode is further improved based on the first implementation mode, and the improvement is that: as shown in fig. 1 and 2 in combination, the conveyor belt device 2 includes:
a driving mechanism 22 for driving the mesh belt 21 to move along the length direction of the furnace body 1;
the gas supply pipeline 3 is connected to the lower part of the mesh belt 21 and supplies the oxidizing gas to the direction of the mesh belt 21.
The mesh belt 21 is used for supporting the fiber composite material and is driven by the driving mechanism 22 to drive the fiber composite material to move. The air holes arranged on the mesh belt 21 are used for the passage of oxidizing gas. The gas supply pipe 3 is connected below the mesh belt 21 and supplies the oxidizing gas in the direction of the mesh belt 21. The oxidizing gas sprayed from the gas supply pipeline 3 can pass through the air holes on the net from the lower part of the net belt 21 and scour the fiber composite material on the upper surface of the net belt 21, so as to realize the purpose of better carbon removal.
The oxidizing gas ejected from the gas supply duct 3 passes through the gas holes from below the mesh belt 21 to primarily oxidize the fiber composite material. The oxidizing gas above the mesh belt 21 is pumped out by the air pumping device, and the oxidizing gas can further oxidize the fiber composite material in the process of moving the oxidizing gas in the furnace body 1. The fiber composite material can completely remove the residual carbon attached to the surface of the fiber through multiple oxidation reactions of the oxidizing gas.
In the present embodiment, the air supply duct 3 includes:
a plurality of main pipelines 31, wherein the main pipelines 31 are connected into the furnace body 1 from the outside of the furnace body 1;
the air distribution device comprises at least two branch pipelines 32, wherein the branch pipelines 32 are arranged at intervals along the length direction or the width direction of the mesh belt 21, and a plurality of air nozzles distributed along the length direction of the branch pipelines 32 are arranged on the branch pipelines 32.
The main pipe 31 is a main pipe for supplying the oxidizing gas into the furnace body 1. The branch pipe 32 is connected to the main pipe 31 and supplies the oxidizing gas to the inside of the furnace body 1. The position of the oxidizing gas sprayed out of the furnace body 1 can be adjusted by controlling the position of the branch line 32 in the furnace body 1.
In the present embodiment, as shown in fig. 2, a plurality of main pipes 31 are connected to the furnace body 1 from outside the furnace body 1, and extend downward from one side of the mesh belt 21 to be connected to branch pipes 32. A plurality of branch pipes 32 are arranged at intervals below the mesh belt 21 in the longitudinal direction of the mesh belt 21, and eject oxidizing gas into the furnace body 1 through gas ejection ports.
Further, in the present embodiment, the temperature control device includes:
the heating chamber 4 is arranged on the inner wall of the furnace body 1, a first electric heating device 41 is arranged in the heating chamber 4, and the first electric heating device 41 is used for heating the inner space of the furnace body 1;
the main conduit 31 passes through the heating chamber 4 and is heated via the heating chamber 4.
It should be noted that the heating chamber 4 is disposed on the furnace body 1, and the whole body may be in a ring structure, and a carbon removing space for performing carbon removing operation is formed in the middle. The first heating means provided in the heating chamber 4 can heat the heating chamber 4 and heat the decarburizing space by heat radiation, thereby heating the fiber composite material in the decarburizing space.
The heating chamber 4 is adapted to heat the space for decarbonation of the fibre composite material in the space for decarbonation, and thereby to heat the fibre composite material located in the space for decarbonation. On the basis that high compressed air is used as a main heat source, the heating chamber 4 of the first electric heating device 41 can be used as an auxiliary heat source to perform auxiliary heating on the fiber composite material, so that the internal temperature of the carbon removing space is ensured to reach the set temperature for performing carbon removing operation on the fiber composite material, and the normal operation of the carbon removing operation is ensured.
In addition, since the main path pipe 31 is connected to the inside of the furnace body 1 and passes through the heating chamber 4 to enter the above-mentioned decarbonizing space, the heating chamber 4 can heat the main path pipe 31 passing through the heating chamber 4.
In practical application, the temperature of the high-pressure compressed air introduced into the main pipeline 31 fluctuates, i.e., the temperature may not be within a specified temperature interval (400 ℃ -500 ℃). Therefore, when the high compressed air having a temperature not within the designated temperature interval passes through the heating zone, it may be influenced by the heating zone to adjust to the designated temperature interval. Specifically, in this embodiment, the temperature in the furnace body 1 should be maintained in a temperature range of 400 ℃ to 500 ℃, and the temperature in the heating chamber 4 should also be maintained in a temperature range of 400 ℃ to 500 ℃. When the high-pressure compressed air introduced into the main pipeline 31 is lower than 400 ℃, the high-pressure compressed air passes through the heating zone and is heated by the heating zone, so that the temperature of the high-pressure compressed air entering the carbon removing space is within the temperature range of 400-500 ℃. When the high-pressure compressed air introduced into the main pipeline 31 is higher than 500 ℃, i.e. higher than the temperature of the heating chamber 4, the heat of the high-pressure compressed air is transferred to the heating chamber 4 when the high-pressure compressed air passes through the heating chamber 4, so that the temperature is reduced to the temperature range of 400-500 ℃. That is, the heating chamber 4 also has a temperature stabilizing function.
It should be noted that, in practical use, the high-pressure compressed air introduced into the main pipeline 31 may be heated air with a temperature close to the specified temperature interval. Through the setting of heating chamber 4, adjust the temperature of high compressed air for the temperature that gets into the high compressed gas in the space that removes carbon is located appointed temperature interval all the time, and then can guarantee to remove the carbon effect.
In this embodiment, in order to prolong the time of the high-pressure air passing through the heating chamber 4 and improve the temperature adjusting effect of the heating chamber 4, the main duct 31 may be at least partially folded into an S-shape in the heating chamber 4.
Third embodiment
The present embodiment is a further improvement based on the second embodiment, and the improvement is that: as shown in fig. 1, the temperature control apparatus further includes: a first temperature sensor disposed in the heating chamber 4 and connected to the first electric heating device 41 in communication.

In this embodiment, the temperature control apparatus further includes:

And the second temperature sensor is respectively arranged in each temperature control area and used for monitoring the temperature in the corresponding temperature control area. In practical application, the temperature of each temperature control area can be monitored in real time through the second temperature sensor, and the corresponding temperature control area is heated through the second electric heating device according to needs, so that the purpose of regulating and controlling the temperature of the local area is achieved.

And monitoring the pressure in the furnace in real time through a pressure sensor, and controlling the gas flow of the gas extraction device and/or the oxidizing gas conveying device according to the pressure in the furnace so as to adjust the pressure in the furnace body 1.
In this embodiment, as shown in fig. 1, the gas exhaust means may comprise a gas exhaust outlet 5 provided on the furnace body 1. The extraction outlet 5 is communicated with the furnace space for exhausting the gas in the furnace.
As shown in fig. 3, the air extracting apparatus may further include:
a fan 51 in communication with the pressure sensor, the fan 51 being disposed opposite the extraction outlet 5;
an air suction duct 6 connected to the air suction outlet 5, wherein the fan 51 is installed in the air suction duct 6, and the blowing direction of the fan 51 faces the direction of the air suction outlet 5;
a non-return valve 52 arranged in said suction duct 6.
Wherein, the fan 51 is arranged in the extraction outlet 5 and blows out towards the furnace body 1. The pressure inside the furnace body 1 is detected by a pressure sensor provided inside the furnace body 1, and the detected pressure inside the furnace body 1 is compared with the outside pressure. According to the comparison result, the rotating speed of the air is controlled to control the air flow of the air exhaust outlet 5, so that the pressure in the furnace body 1 is adjusted, the pressure in the furnace body 1 is slightly smaller than the external pressure, and the furnace body 1 is in a micro-negative pressure state.
The exhaust duct 6 may be a transfer duct for transferring the gas in the furnace body 1 to another location, or may be a bypass duct connected in parallel to one side of the transfer duct. The bypass line may be connected in a temporary gas storage facility. In this embodiment, as shown in fig. 3, the pumping duct 6 is a delivery duct for delivering the gas generated by the reaction to another location, and the blower 51 is directly disposed in the delivery duct.
In addition, the gas flowing direction of the check valve 52 is the direction of the gas to be transported from the inside of the furnace body 1 to the outside, so that smooth transportation of the gas in the furnace body 1 to the outside can be ensured, and the problem of over-high pressure in the furnace caused by reverse transportation of the gas into the furnace body 1 due to the gas pressure can be avoided.
Fifth embodiment
The embodiment is a further improvement based on the fourth embodiment, and the improvement is that, as shown in fig. 1, the conveyor type carbon removing furnace further comprises:
the discharge pipeline 7 is connected to the furnace body 1;
the mesh belt 21 extends out of the furnace body 1 through the discharge pipeline 7.
The discharging pipeline 7 corresponds to a discharging port on the furnace body 1 and is used as a buffer space between the inside and the outside of the furnace body 1. Through the setting of ejection of compact pipeline 7, can reduce the influence of external world to the temperature in the furnace body 1 to ensure the normal clear of the inside decarbonization operation of furnace body 1.
In this embodiment, the discharge pipe 7 forms a first included angle with the horizontal plane, and the first included angle is within a range from 10 ° to 35 °.
Specifically, the discharge duct 7 is inclined downward from the side of the furnace body 1 toward the direction in which the mesh belt 21 moves to have a first angle with the horizontal plane. Due to the rising principle of hot air, when high-temperature gas in the furnace is positioned in the discharge pipeline 7, the high-temperature gas is difficult to continue to move downwards along the discharge pipeline 7 in the discharge pipeline 7 inclined downwards, the leakage condition of the high-temperature gas to the outside can be reduced to a certain extent, and the external gas can be prevented from entering the furnace body 1 along the discharge pipeline 7.

Therefore, the moving direction of the high-temperature gas in the discharge duct 7 is inclined upward toward the furnace body 1 under the action of the temperature and the pressure difference between the inside of the furnace and the outside. The applicant finds that when the moving direction of the high-temperature gas in the discharge pipeline 7 is the same as or close to the extending direction of the discharge pipeline 7, the leakage condition of the high-temperature gas is less, and the isolation effect on the external gas is better.
Therefore, the first included angle is preferably in the range of 10 ° to 35 ° through many experimental adjustments of the applicant in consideration of the above various factors in combination. At this moment, the moving direction of the high-temperature gas in the discharge pipeline 7 is the same as or close to the extending direction of the discharge pipeline 7, the leakage condition of the high-temperature gas is less, the isolation effect on the external gas is better, and the energy can be effectively saved.
It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential attributes thereof.
