Oil-containing solid material treatment system

Technical Field

The embodiment of the disclosure relates to an oil-containing solid material treatment system.

Background

The thermal phase separation technology is firstly applied to soil organic matter remediation. With the continuous improvement and perfection of the technology, the technology is gradually applied to the field of oil-based drilling waste treatment. The thermal phase separation technology can be divided into a direct heating technology and an indirect heating technology, and the indirect heating technology is more applied. The method is characterized in that a high-temperature heating cavity generated by an external heat source is utilized, heat energy is transferred to solid waste to evaporate volatile substances contained in the solid waste, and the solid waste is recycled through a condensing tower and separation equipment. At present, there are four main ways of indirect heating: heat transfer oil heating, natural gas/oil combustion open fire heating, electric heating and microwave heating. In the four modes, although the heating by the natural gas/oil burning open fire is widely applied, a large amount of smoke is generated in the operation process, and the smoke is treated by a smoke treatment device and can be discharged after reaching the standard; in addition, the heating mode has low heat transfer efficiency, uneven heating, incapability of accurately controlling the temperature and higher requirements on materials of a furnace body; it cannot be used in some places where open fire is limited.

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The use of "first," "second," and similar terms in the description and claims of the present disclosure are not intended to indicate any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprise" or "comprises", and the like, means that the element or item listed before "comprises" or "comprising" covers the element or item listed after "comprising" or "comprises" and its equivalents, and does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

The inventor notices that for the existing horizontal reaction kettle, because the electromagnetic heater can heat the upper space without the oil-containing solid waste and the lower space with the oil-containing solid waste in the horizontal reaction kettle at the same time at the same temperature, the reaction kettle can be deformed due to uneven heating. For the existing vertical reaction kettle, the electromagnetic heater heats the whole vertical reaction kettle. Therefore, the filling rate of the materials is gradually reduced in the heating process, and the space without the solid materials at the upper part and the space filled with the fixed materials at the lower part are heated at the basically same temperature, so that the reaction kettle is heated unevenly to deform, and larger energy waste is caused.

The embodiment of the present disclosure provides an oily solid material processing system, including: the device comprises a thermal phase separation module, a thermal desorption steam processing module and a noncondensable gas processing module which are sequentially communicated in a gas flowing direction. The thermal phase separation module includes: the vertical furnace body, (mixing) shaft and electromagnetic induction heating coil subassembly. The vertical furnace body comprises a top wall, a bottom wall and a side wall, wherein the top wall and the bottom wall are opposite to each other in the height direction, and the side wall is connected with the top wall and the bottom wall, and the top wall, the bottom wall and the side wall enclose a heat treatment cavity extending in the height direction. The stirring shaft is connected with the vertical furnace body, and one part of the stirring shaft is positioned in the heat treatment cavity. The electromagnetic induction heating coil assembly includes a plurality of coil units that are sequentially disposed on the outer side of the side wall of the vertical furnace body in the height direction. The heating power of each electromagnetic induction heating coil unit can be independently controlled.

Another embodiment of the present disclosure provides a method for treating an oil-containing solid material, including: filling a heat treatment cavity of a vertical furnace body with oil-containing solid materials to be treated, wherein the heat treatment cavity is surrounded by a top wall, a bottom wall and a side wall connecting the top wall and the bottom wall, an electromagnetic induction heating coil assembly is arranged on the outer side of the side wall of the vertical furnace body, and the electromagnetic induction heating coil assembly comprises a plurality of coil units which are sequentially arranged in the vertical direction; turning on at least a part of the plurality of coil units to enter a heating state so as to heat the oily solid material to be treated in the heat treatment cavity; determining at least one of the opened at least one part of the plurality of coil units as a coil unit to be regulated according to the change of the filling rate of the oily solid material to be treated in the heat treatment cavity, and determining at least another one of the opened at least one part of the plurality of coil units as a reference coil unit, wherein the reference coil unit is closer to the bottom wall of the vertical furnace body than the coil unit to be regulated in the vertical direction; and reducing the heating power of the coil unit to be regulated under the condition of keeping the reference coil unit in the heating state.

Therefore, on one hand, the oil-based drilling waste can be treated while drilling due to the adoption of an electromagnetic induction heating mode; on the other hand, because the heating range and the heating power of a plurality of coil units of the electromagnetic induction heating coil assembly are adjusted along with the filling degree of the solid materials in the heat treatment cavity, the deformation caused by nonuniform heating of the furnace body can be effectively avoided, and the energy consumption is reduced.

FIG. 1 is a schematic block diagram illustrating various modules and their connectivity of an oil-bearing solid material handling system provided by an embodiment of the present disclosure; fig. 2 shows a schematic cross-sectional structure diagram of a thermal phase separation module of an oily solid material processing system provided by an embodiment of the disclosure.

Referring to fig. 1 and 2, a system for processing oil-containing solid materials provided by the embodiment of the present disclosure includes: the system comprises a feeding module M1, a thermal phase separation module M2, a thermal desorption steam treatment module M3, a non-condensable gas treatment module M4 and a discharging module M5.

The thermal phase separation module M2, the thermal desorption steam treatment module M3 and the noncondensable gas treatment module M4 are sequentially communicated in a gas flowing direction. Here, the gas flow direction refers to, for example, a flow direction of the gas in the thermal phase separation module M2, the thermal desorption vapor treatment module M3, and the non-condensable gas treatment module M4. The gas may be gas from the oily solid material to be treated or air.

The feeding module M1, the thermal phase separation module M2 and the discharging module M5 are communicated in sequence in the flow direction of the solid material. Here, the solid material flow direction refers to, for example, the moving direction of the oil-containing solid material to be treated in the feeding module M1, the thermal phase separation module M2, and the discharging module M5.

The thermal phase separation module M2 includes: a vertical furnace body 206, a stirring shaft 203 and an electromagnetic induction heating coil assembly 205.

The vertical furnace body 206 includes a top wall 2061 and a bottom wall 2062 opposed to each other in the height direction Y and a side wall 2063 connecting the top wall 2061 and the bottom wall 2062. Here, the height direction Y is, for example, a vertical direction. In the height direction Y, for example, the side walls 2063 do not overlap with either of the top wall 2061 and the bottom wall 2062. In this embodiment, for example, the top wall 2061 and the bottom wall 2062 are both substantially flat walls, and the side wall 2063 is a cylindrical side wall. For example, the vertical furnace body 206 is made of carbon steel to meet the requirement of the electromagnetic induction heating coil assembly on the furnace body material.

The top wall 2061, the bottom wall 2062, and the side walls 2063 enclose a heat treatment chamber C extending in the height direction Y. For example, the thermal processing chamber C has a substantially cylindrical shape. It is understood that the embodiments of the present disclosure are not limited to the particular shape of the top wall 2061, the side walls 2063 of the bottom wall 2062, and the heat treatment chamber C of the vertical furnace 206.

For example, the stirring shaft 203 is a spiral stirring shaft 203, the spiral stirring shaft 203 is rotatably connected to the vertical furnace body 206, and a part of the spiral stirring shaft 203 is located in the heat treatment chamber C. The part of the spiral stirring shaft 203, which is located in the heat treatment chamber C, is provided with an external thread structure 2031 so as to drive the oily material to be treated, which is located in the heat treatment chamber C, to move in the heat treatment chamber C. Here, the concrete form of the stirring shaft 203 is not limited.

The electromagnetic induction heating coil assembly 205 includes a plurality of coil units that are sequentially disposed on the outer side of the side wall 2063 of the vertical furnace body 206 in the height direction Y. Here, the outer side of the side wall 2063 refers to the side of the side wall 2063 opposite the heat treatment chamber C. The heating power of each coil unit is configured to be independently controlled. That is, the heating power of any one coil unit can be controlled independently of the remaining all coil units. Here, the heating power of the coil unit has a value equal to or greater than zero. The heating power of the coil unit corresponds to the heating temperature provided by the coil unit to the vertical furnace body. When the heating power of the coil unit is zero, the coil unit is in a power-off closing state; when the heating power of the coil unit is greater than zero, it indicates that the coil unit is in a heating state for heating the vertical furnace body 206.

Like this, adopt the adjustable mode of heating of vertical electromagnetism segmentation, can realize the accurate accuse temperature of segmentation according to the filling rate adjustment heating range of the solid material in the heat treatment chamber C, carry out indirect heating to the vertical furnace body to avoid the vertical furnace body to take place unfavorable deformation owing to being heated unevenly, and can reduce the energy consumption of electromagnetic induction heating coil assembly on the basis that prevents to warp.

Referring to fig. 2, the electromagnetic induction heating coil assembly 205 includes 5 coil units L1 to L5. Each of the coil units L1 to L5 includes three coils. For example, the height of each of the coil units L1 to L5 in the height direction Y is the same. Embodiments of the present disclosure do not limit the number of coil units included in the electromagnetic induction heating coil assembly 205, the number of coils included in each coil unit, and the height of each coil unit in the height direction.

For example, the plurality of coils in the electromagnetic induction heating coil assembly 205 are arranged at equal intervals in the height direction Y. In this way, the heating zones of the electromagnetic induction heating coil assembly 205 may be more uniformly controlled.

For example, the thermal phase separation module M2 further includes an insulating layer 207 covering the outer surfaces of the top wall 2061, the bottom wall 2062, and the side walls 2063 of the vertical furnace body 206. The outer surfaces of the top wall 2061, the bottom wall 2062, and the side walls 2063 are the surfaces of the top wall 2061, the bottom wall 2062, and the side walls 2063 that are opposite to the heat treatment chamber C. A portion of the insulation layer 207 is located between the vertical furnace body 206 and the electromagnetic induction heating coil assembly 205. For example, the heat insulating layer 207 is mainly made of ceramic fiber wool and covered with glass fiber cloth. Therefore, the heat loss of the equipment in the operation process can be reduced, the electromagnetic induction heating coil can be prevented from being directly contacted with the furnace body to be damaged, and the uniformity of the temperature in the heat treatment cavity C can be effectively improved.

FIG. 3 shows a flow chart of a method for processing oil-containing solid materials provided by the embodiment of the disclosure; fig. 4A to 4C are schematic diagrams illustrating adjusting heating power of a coil unit of an electromagnetic induction heating coil assembly according to a filling degree of a solid material in a vertical furnace body in a processing method of an oil-containing solid material provided by an embodiment of the present disclosure.

For example, each of the illustrated thermal phase separation modules of fig. 4A to 4C may be the thermal phase separation module M2 illustrated in fig. 2. Fig. 4A to 4C schematically show only the thermal phase separation module M2 by a rectangular vertical furnace body 206 and a plurality of coil units L1 to L5, and the openings in the top wall 2061 and the bottom wall 2062 of the vertical furnace body 206, the spiral stirring shaft 203, the insulating layer 207, and the like are omitted.

The oily solid material processing method provided by any embodiment of the disclosure can be implemented by adopting the oily solid material processing system provided by any embodiment of the disclosure.

Referring to fig. 3 to 4C, another embodiment of the present disclosure provides a method for treating an oil-containing solid material, including:

filling a heat treatment chamber C of a vertical furnace body 206 with an oil-containing solid material SW to be treated, wherein the heat treatment chamber C is surrounded by a top wall 2061, a bottom wall 2062 and a side wall 2063 connecting the top wall 2061 and the bottom wall 2062, an electromagnetic induction heating coil assembly 205 is arranged on the outer side of the side wall 2063 of the vertical furnace body 206, and the electromagnetic induction heating coil assembly 205 comprises a plurality of coil units L1-L5 which are sequentially arranged in the vertical direction Y; here, the oil-containing solid material SW is, for example, oil-based drilling waste;

at least one part of the coil units L1-L5 is opened to enter a heating state so as to heat the oily solid material SW to be processed in the heat processing cavity C;

determining at least one of the opened at least one part of the plurality of coil units L1-L5 as a coil unit to be regulated according to the size change of the filling rate of the oily solid material to be treated in the heat treatment cavity C, and determining at least another one of the opened at least one part of the plurality of coil units L1-L5 as a reference coil unit, wherein the reference coil unit is closer to the bottom wall 2062 of the vertical furnace body 206 than the coil unit to be regulated in the vertical direction Y; and

the heating power of the coil unit to be regulated is reduced while keeping the reference coil unit in a heated state.

Here, the change in the filling rate of the oily solid material to be treated in the heat treatment chamber C corresponds to the height position in the vertical direction Y of the surface of the oily solid material to be treated facing the top wall 2061.

The vertical direction Y refers to a direction of gravity, for example, the vertical direction Y is substantially perpendicular to the horizontal direction. The plurality of coil units L1 to L5 arranged in this order in the vertical direction Y means, for example, that the height positions of the plurality of coil units L1 to L5 in the vertical direction Y gradually rise or fall, but the relative positional relationship of the plurality of coil units L1 to L5 in the horizontal direction is not limited.

It will be understood that when the filling rate of the oily solid material to be treated in the heat treatment chamber C is relatively large, the height position of the surface of the oily solid material to be treated facing the top wall 2061 in the vertical direction Y is at a relatively high position (i.e., a position relatively close to the top wall 2061); when the filling rate of the oily solid material to be treated in the heat treatment chamber C is relatively small, the height position of the surface of the oily solid material to be treated facing the top wall 2061 in the vertical direction Y is at a relatively low position (i.e., a position relatively far from the top wall 2061).

Here, the reduction of the heating power of the coil unit to be regulated means the reduction of the heating temperature provided by the coil unit to be regulated to the vertical furnace body 206.

Reducing the heating power of the coil unit to be regulated includes reducing the heating power of the coil unit to be regulated to zero. Reducing the heating power of the coil unit to be regulated to zero means that the coil unit to be regulated is changed from a heating state of power-on to a non-heating state of power-off closing.

Reducing the heating power of the coil unit to be regulated further comprises reducing the heating power of the coil unit to be regulated from a larger value to a smaller value larger than zero. Reducing the heating power of the coil unit to be regulated from a larger value to a smaller value larger than zero means that the coil unit to be regulated is changed from a heating state providing a higher heating temperature to a heating state providing a lower heating temperature.

Therefore, under the condition that the upper space is not filled with the solid materials due to the fact that the filling rate of the solid materials in the heat treatment cavity is gradually reduced, heating of the upper space can be reduced, the temperature at each position in the heat treatment cavity is guaranteed to be uniform, the vertical furnace body is prevented from generating unfavorable deformation, and energy consumption of the coil unit can be saved on the basis of avoiding deformation.

Compared with the condition that the coil unit to be regulated is switched off, the coil unit to be regulated is regulated into a lower-temperature heating state, and the temperature uniformity of all parts in the heat treatment cavity can be better maintained.

For example, reducing the heating power of the coil unit to be regulated while keeping the reference coil unit in the heating state includes: the heating power of the coil unit to be regulated is reduced by 60% to 90% while keeping the reference coil unit in a heated state. For example, the heating power of the coil unit to be controlled is reduced from 100KW to 20 KW.

Referring to fig. 4A to 4C, each coil unit provides a reference position between its position closest to the top wall and its position closest to the bottom wall in the vertical direction. Specifically, the coil unit L1 provides a reference position R1 between a position L12 closest to the top wall and a position L11 closest to the bottom wall in the vertical direction Y; the coil unit L2 provides a reference position R2 between a position L22 closest to the top wall and a position L21 closest to the bottom wall in the vertical direction Y; the coil unit L3 provides a reference position R3 between a position L32 closest to the top wall and a position L31 closest to the bottom wall in the vertical direction Y; the coil unit L4 provides a reference position R4 between a position L42 closest to the top wall and a position L41 closest to the bottom wall in the vertical direction Y; the coil unit L5 provides a reference position R5 between a position L52 closest to the top wall and a position L51 closest to the bottom wall in the vertical direction Y. Each coil unit overlaps with a reference position provided thereto in a horizontal direction X perpendicular to the vertical direction Y.

It will be appreciated that although the various reference positions are indicated by dots in fig. 4A to 4C, any one reference position is not specific to a particular physical structure, but is merely used for comparison with the position in the vertical direction Y of the surface of the oily solid material to be treated facing the top wall.

Determining at least one of the opened at least one part of the plurality of coil units L1-L5 as a coil unit to be regulated according to the change of the filling rate of the oily solid material to be treated in the heat treatment chamber C comprises: when the surface of the oily solid material to be treated facing the top wall 2601 is not higher than at least one reference position in the vertical direction Y, the coil unit providing the at least one reference position is determined as the coil unit to be regulated.

Hereinafter, referring to fig. 4A to 4C, a process of adjusting heating power of a coil unit of an electromagnetic induction heating coil assembly according to a solid material filling degree in a vertical furnace in one example will be described in detail.

Referring to fig. 4A, the oily solid material SW to be treated is filled in the thermal reaction chamber C of the vertical furnace body 206. The surface S1 of the oily solid matter SW to be treated facing the top wall 2061 is higher than the reference position R5 provided by the coil unit L5. In this case, for example, all the coil units L1 to L5 are turned on to heat the oily solid matter SW to be treated at the same heating power.

Referring to fig. 4B, when the height of the oily solid matter SW to be treated in the thermal reaction chamber C of the vertical furnace body 206 is reduced so that the surface S2 of the remaining oily solid matter SW' to be treated facing the top wall 2061 is not higher than the reference position R5 provided by the coil unit L5, the coil unit L5 providing the reference position R5 is determined as the coil unit to be regulated, and the coil unit L1 is determined as the reference coil unit. The heating power of the coil unit to be regulated L5 is reduced. In this case, the coil units L1 to L4 still maintain the original heating power to heat the remaining oily solid matter SW' to be treated.

Referring to fig. 4C, when the height of the remaining oily solid material SW' to be processed in the thermal reaction chamber C of the vertical furnace 206 is further reduced to a level at which the surface S3 of the remaining oily solid material SW ″ to be processed facing the top wall 2061 is not higher than the reference position R4 provided by the coil unit L4, the coil unit L4 providing the reference position R4 may be determined as a coil unit to be regulated, and the heating power of the coil unit L4 to be regulated is reduced. In this case, the coil units L1 to L3 still maintain the original heating power to heat the remaining oil-containing solid material SW' to be treated. The heating power of the coil units L3, L2 and L1 may be reduced in sequence by analogy.

In another example, when the surface S2 of the remaining oily solid matter SW' to be treated facing the top wall 2061 is not higher than the reference position R5 provided by the coil unit L5 but higher than the reference position R4 provided by the coil unit L4, the coil unit L5 can still maintain the original heating power; when the surface S3 of the remaining oily solid matter SW ″ to be treated facing the top wall 2061 is not higher than the reference position R4 provided by the coil unit L4, it is possible to determine both the coil unit L5 providing the reference position R5 and the coil unit L4 providing the reference position R4 as coil units to be regulated, and simultaneously reduce the heating power of the coil units L4 and L5 to be regulated. The disclosed embodiments do not limit the order of decreasing the heating power of the coil units L5 to L1.

In the vertical direction, for at least one coil unit, a first distance between a reference position provided by the coil unit and a position closest to the bottom wall is greater than or equal to 5cm and less than or equal to 10 cm. Thus, the uniformity of the temperature in the thermal processing chamber C can be more advantageously improved. For example, the distance between the position L11 at which the coil unit L1 is closest to the bottom wall in the vertical direction Y and the reference position R1 is 7 cm; the distance between the position L21 of the coil unit L2 closest to the bottom wall in the vertical direction Y and the reference position R2 is 7 cm; the distance between the position L31 of the coil unit L3 closest to the bottom wall in the vertical direction Y and the reference position R3 is 7 cm; the distance between the position L41 of the coil unit L4 closest to the bottom wall in the vertical direction Y and the reference position R4 is 7 cm; the distance between the position L51 of the coil unit L5 closest to the bottom wall in the vertical direction Y and the reference position R5 is 7 cm.

For example, referring to fig. 2, embodiments of the present disclosure provide an oil-containing solid material processing system further comprising a position detector P located on a side of the top wall 2061 of the vertical furnace 206 facing the bottom wall. The detector P is configured to detect the height position in the height direction of the surface of the solid material facing the top wall in the heat treatment chamber C of the vertical furnace body 206. The position detector P is, for example, a laser range finder. The position detector P and the coil units L1-L5 are all electrically connected to the control unit. The control unit may automatically perform the above-described processing method according to the relationship between the height position of the surface of the solid material facing the top wall in the height direction in the heat treatment chamber C detected by the position detector P and the reference positions R1 to R5.

Fig. 5 is a schematic diagram illustrating components and communication relationships of modules of an oil-containing solid material processing system according to an embodiment of the present disclosure.

Referring to fig. 5, the thermal desorption steam treatment module M3 includes: a first condenser 501 and a first liquid storage tank 601 connected in series between the vertical furnace 206 and the non-condensable gas processing module M4, a second condenser 502 and a second liquid storage tank 602 connected in series between the vertical furnace 206 and the non-condensable gas processing module M4, and a first valve assembly. The vertical furnace 206 is connected to the first condenser 501 and the second condenser 502 via a first valve assembly. The first valve assembly is configured to switch between a first communication state and a second communication state. The first communication state is that the heat treatment chamber C of the vertical furnace body 206 is communicated with the first condenser 501 but not communicated with the second condenser 502; the second communication state is that the heat treatment chamber C of the vertical furnace body 206 communicates with the second condenser 502 and does not communicate with the first condenser.

For example, the first condenser 501 and the second condenser 502 are each a tube condenser.

Specifically, the first valve assembly includes, for example, a first valve K1 and a second valve K2.

A first valve K1 is provided on a first line G1 communicating the heat treatment chamber C of the vertical furnace body 206 with the first condenser 501 to control the conducting state of the first line G1.

The second valve K2 is provided on the second line G2 communicating the heat treatment chamber C of the vertical furnace body 206 with the second condenser 502 to control the conduction state of the second line G2.

For example, the first valve K1 and the second valve K2 are each a thermostatic valve.

The first valve K1 is configured to be in an open state such that the heat treatment chamber C and the first condenser 501 communicate via the first pipe G1 in the case where the monitored temperature is equal to or less than the first temperature, and to be in a closed state such that the heat treatment chamber C and the first condenser 501 do not communicate in the case where the monitored temperature is greater than the first temperature.

The second valve K2 is configured to be in a closed state such that the heat treatment chamber C is not communicated with the second condenser 502 in a case where the monitored temperature is equal to or less than the first temperature, and to be in an open state such that the heat treatment chamber C is communicated with the second condenser 502 via the second pipe G2 in a case where the monitored temperature is greater than the first temperature.

For example, the first valve K1 and the second valve K2 are each configured to be manually switchable. That is, the on-off state of each of the first valve K1 and the second valve K2 may be manually controlled.

Here, the monitored temperature is the temperature of the heat treatment chamber C or the temperature of the chamber between the heat treatment chamber C and the first and second condensers 501 and 502 in the gas flow direction. The temperature of the chamber may refer to the temperature of any location in the chamber.

Therefore, according to different time stages of generating water vapor and oil vapor in the thermal phase separation process, the two distillate gases can respectively enter the two sets of condensers in a directional mode, and oil and water are recovered independently. The two condensers can also be mutually standby, so that the long-term stable operation of the treatment system is ensured.

It is to be understood that the disclosed embodiments are not limited to the specific structure of the first valve assembly. For example, in another example, the first valve component may be, for example, a three-way diverter valve, a fluid inlet of the three-way diverter valve is communicated with the heat treatment chamber C of the vertical furnace 206, and two fluid outlets of the three-way diverter valve are communicated with the first condenser 501 and the second condenser 502, respectively. The three-way flow dividing valve may be, for example, a temperature control valve configured to communicate the heat treatment chamber C with the first condenser 501 and not with the second condenser 502 in the case where the monitored temperature is equal to or lower than the first temperature, and to communicate the heat treatment chamber C with the second condenser 502 and not with the first condenser 501 in the case where the monitored temperature is higher than the first temperature.

For example, the oily solid material processing system provided by the embodiment of the present disclosure further includes: a tubular member 204 and a temperature sensor T. The tubular member 204 communicates with the heat treatment chamber C at the first opening K1 of the top wall 2061 of the vertical furnace body. A temperature sensor T is located in the lumen of the tubular member 204. The temperature sensor T is located on the side of the top wall 2061 opposite to the bottom wall in the height direction. The temperature sensor T is configured to provide the above-described monitored temperature. The temperature sensor T is, for example, a thermocouple.

For example, a plurality of additional inductive probes are disposed inside the vertical furnace body 206, so that parameters such as the air pressure in the thermal processing chamber C can be monitored in real time.

For example, the first valve K1, the second valve K2, and the temperature sensor T are all electrically connected to the control unit, for example, so that the on-off states of the first valve K1 and the second valve K2 can be controlled by the control unit according to a temperature signal measured by the temperature sensor T. In addition, in the case where any one of the first condenser 501 and the second condenser 502 malfunctions, the control unit may realize the selection of different condensing passages by controlling the switching states of the first valve K1 and the second valve K2.

For example, the first condenser 501 and the second condenser 502 are connected to the first tank 601 and the second tank 602 through a second valve assembly.

The second valve assembly is configured to be switchable between at least a third communication state, a fourth communication state, and a fifth communication state.

The third communication state is that the first condenser 501 communicates with the first tank 601 without communicating with the second tank 602, and the second condenser 502 communicates with the second tank 602 without communicating with the first tank 601.

The fourth communication state is that the first condenser 501 communicates with the second tank 602 but does not communicate with the first tank 601.

The fifth communication state is that the second condenser 502 communicates with the first tank 601 but does not communicate with the second tank 602.

For example, referring to fig. 5, the second valve assembly comprises: a third valve, a fourth valve, and a fifth valve.

A third valve K3 is provided on a third line G3 that communicates the first condenser 501 with the first tank 601 to control the conducting state of the third line G3;

a fourth valve K4 is disposed on a fourth line G4 connecting the second condenser 502 and the second liquid storage tank 602 to control the on state of the fourth line G4;

a fifth valve K5 is provided on the fifth line G5 communicating the third line G3 and the fourth line G4 to control the conduction state of the fifth line G5.

In this way, in the case where any one of the first condenser 501, the second condenser 502, the first tank 601 and the second tank 602 is not available, the condensing passage in the thermal desorption vapor treatment module M3 can be selected and controlled by the first valve assembly and the second valve assembly.

In another example, first condenser 501 is in direct communication with first reservoir 601 through a third line G3, and second condenser 502 is in direct communication with second reservoir 602 through a fourth line G4; no valves are provided in the third line G3 and the fourth line G4, and the third line G3 and the third line G4 are not in communication.

For example, in the method for processing oily solid materials provided by the embodiment of the present disclosure, at least a portion of the plurality of coil units L1 to L5 is turned on to heat the oily solid materials to be processed in the thermal processing chamber C, including:

During a second time period, a second fraction evaporated from the oily solid material to be treated is condensed and collected by means of a second condensation line communicating with the thermal treatment chamber.

Here, the first condensing line may be a line formed by the first line G1 of the first valve K1, the first condenser 501, the third line G3, and the first tank 601 shown in fig. 5. The second line may be the line formed by the first line G2, the second condenser 502, the fourth line G4 and the second tank 602 of the second valve K2 shown in fig. 5.

And in a first time period, the gas pressure in the heat treatment cavity is a first pressure, and the first temperature is greater than or equal to a first boiling point temperature of water under the first pressure and less than a second boiling point temperature of the oil-based substances in the oil-containing solid material under the first pressure.

And in a second time period, the gas pressure in the heat treatment chamber is a second pressure, and the second temperature is greater than or equal to a third boiling point temperature of the oil-based substances in the oil-containing solid material under the second pressure.

For example, the first pressure and the second pressure are both substantially equal to 20 KPa. In another example, the first pressure and the second pressure may not be substantially equal.
