Description

Technical Field

[0001] The invention belongs to the technical field of thermal engineering, and in particular relates to a heat source supply device. Background Art

[0002] Industrial high-temperature kiln calcination (sintering, roasting, smelting) is an indispensable production link in cement, lime, glass, ceramics, steam boilers, industrial boilers, steelmaking, chemical industry, waste incineration, solid waste disposal, environmental protection and other industrial fields. Conventional heating is achieved by burning fossil fuels, which will produce a large amount of carbon dioxide emissions during the combustion of fossil fuels and cannot meet the requirements of carbon dioxide emission reduction.

[0003] Traditional industrial high-temperature kilns mainly use fossil energy such as coal, oil, and natural gas as fuel. During the combustion process, they need air and oxygen to replenish, which will inevitably produce a large amount of smoke and nitrogen oxides (NO). X The fuel itself will also produce various waste gases such as SO2 and CO2 due to its different composition. If it is discharged directly, it will inevitably cause varying degrees of pollution to the atmosphere and the environment, especially the large-scale emission of CO2, which poses a severe challenge to my country's realization of the carbon neutrality goal. Therefore, changing the heating (heat source supply) method of industrial kilns is a very arduous task and mission.

[0004] Traditional industrial kilns use fossil fuels to provide heat sources, and their thermal efficiency is not high, only about 35%-40%, resulting in a huge waste of resources and producing a large amount of fuel waste residue. The fuel waste residue also puts great pressure on the control of environmental pollution. Summary of the invention

[0090] like Figure 1-Figure 11 As shown, according to an embodiment of the present invention, a heat source supply device is proposed, which uses a mixed gas in a high-temperature plasma state generated by ionizing a working gas to replace the high-temperature flue gas generated by the combustion of fossil fuels as a heat source, which helps to solve the problems of low thermal efficiency and easy generation of a large amount of fuel waste in existing industrial furnaces.

[0091] In terms of overall design, the heat source supply device includes a main body 1, a plasma generating assembly and an air inlet assembly 5. The main body 1 has an air inlet 101 and an air outlet 102, and a heating channel 103 for connecting the air inlet 101 and the air outlet 102. The plasma generating assembly includes a first electrode rod 21 and a second electrode rod 22 arranged at intervals on the main body 1, and the first electrode rod 21 and the second electrode rod 22 are both located on a first straight line, and the first straight line is perpendicular to the extension direction of the heating channel 103. The first electrode rod 21 has a first working end, and the second electrode rod 22 has a second working end. The first working end and the second working end are arranged inside the heating channel 103, and a discharge distance can be maintained between the first working end and the second working end. The air inlet assembly 5 is used to input working gas into the air inlet 101. The working gas is used to be converted into plasma between the first working end and the second working end.

[0092] The heat source supply device of the present invention can transform the gas between the first electrode rod 21 and the second electrode rod 22 into plasma by arranging the first electrode rod 21 and the second electrode rod 22 on the main body 1 and inputting direct current into the first electrode rod 21 and the second electrode rod 22. At this time, the gas in the plasma state can be mixed with the working gas introduced from the air intake component 5 to form a gas with high speed and high temperature, thereby achieving the purpose of generating high-temperature gas by ionizing the working gas. The high-temperature gas can be used as a heat source for industrial furnaces instead of high-temperature flue gas generated by the combustion of fossil fuels, which helps to achieve zero emission of carbon dioxide in the entire heating process and reduce pollution to the environment. In addition, the heat source supply device also has a good heat conversion efficiency to improve resource utilization.

[0093] Specifically, if Figure 1-Figure 4 As shown, the above-mentioned main body 1 includes a reaction tube 12, a first end cap 11, a second end cap 13 and a support column 14, wherein the support column 14 is fixedly arranged on a mounting base, and the mounting base can be the ground or a mounting plate. The reaction tube 12 is connected to the top of the support column 14, and the first end cap 11 and the second end cap 13 are respectively arranged at the opposite ends of the reaction tube 12, and the first end cap 11 and the second end cap 13 are sealed and connected with the reaction tube 12. In the present embodiment, the main body 1 has an air inlet 101 and an air outlet 102, and a heating channel 103 is arranged between the air inlet 101 and the air outlet 102. Preferably, the air inlet 101 is arranged on the first end cap 11, the air outlet 102 is arranged on the second end cap 13, and the heating channel 103 is arranged on the reaction tube 12, and is arranged in the horizontal direction. At the same time, the first end cover 11 can be sealed and connected to the air intake assembly 5 so that the working gas output by the air intake assembly 5 can flow through the air inlet 101, the heating channel 103 and the air outlet 102 in sequence.

[0094] It should be understood that the material of the main body 1 can be made of one of carbon steel, low alloy steel or high alloy steel, and the specific material selection of the main body 1 can be determined by the heating temperature required to be achieved by the heat source supply device, which will not be described in detail here.

[0095] At this time, the first electrode rod 21 and the second electrode rod 22 are inserted through the main body 1, and the first electrode rod 21 and the second electrode rod 22 are arranged opposite to each other. Specifically, the first electrode rod 21 and the second electrode rod 22 are both inserted through the reaction tube 12 of the main body 1, and the first electrode rod 21 and the second electrode rod 22 are both located on the first straight line. In this embodiment, the first straight line is a vertical line, and at this time, the first straight line is perpendicular to the extension direction of the heating channel 103. Figure 6 As shown, the first electrode rod 21 is arranged at the top of the reaction tube 12, and the second electrode rod 22 is arranged at the bottom of the reaction tube 12. Parts of the first electrode rod 21 and the second electrode rod 22 are both inserted into the heating channel 103, and are arranged at intervals in the heating channel 103. Specifically, the first electrode rod 21 has a first working end, and the second electrode rod 22 has a second working end. The first working end and the second working end are arranged inside the heating channel, and a discharge distance can be maintained between the first working end and the second working end.

[0096] It should be understood that the first electrode rod 21 and / or the second electrode rod 22 can move along the first straight line, so as to achieve the approach or distance between the first electrode rod 21 and the second electrode rod 22, that is, the first electrode rod 21 and the second electrode rod 22 are movably arranged on the main body 1. Such a configuration enables the heat source supply device to adjust the discharge distance between the first working end and the second working end, and when direct current is passed through the first electrode rod 21 and the second electrode rod 22, to achieve regulation of the plasma state conversion rate of the gas, thereby achieving adjustment of the working gas temperature between the first working end and the second working end.

[0097] In addition, in the present embodiment, the first electrode rod 21 and the second electrode rod 22 are both connected to a current supply member disposed outside the main body 1, and the current supply member is not shown in the figure. Specifically, the first electrode rod 21 also has a first connection end, and the second electrode rod 22 also has a second connection end. The first connection end is disposed opposite to the first working end, and the second connection end is disposed opposite to the second working end. Preferably, the positive and negative electrodes of the current supply member are respectively connected to the first connection end of the first electrode rod 21 and the second connection end of the second electrode rod 22, and direct current is output to the first electrode rod 21 and the second electrode rod 22. The current supply member can adjust the size of the input direct current, and regulate the temperature between the first working end and the second working end in accordance with the different discharge distances.

[0098] It should be further understood that the heat source supply device also includes a delivery mechanism, which is used to drive the movement of the first electrode rod 21 and the second electrode rod 22 to achieve the above-mentioned first electrode rod 21 and the second electrode rod 22 to move closer or farther away. Specifically, the delivery mechanism includes a clamping assembly and a driving member, wherein the clamping assembly is used to clamp the first electrode rod 21 and / or the second electrode rod 22 located outside the main body 1, and the driving member is used to drive the clamping assembly to move along the first straight line. In this embodiment, the number of delivery mechanisms is two, and the structures of the two delivery mechanisms are the same. For the convenience of description, the two delivery mechanisms are respectively referred to as the first delivery mechanism and the second delivery mechanism. Among them, the first delivery mechanism is used to drive the first electrode rod 21 to move, and the second delivery mechanism is used to drive the second electrode rod 22 to move.

[0099] Specifically, the first delivery mechanism includes a first driving member 31 and a first clamping assembly 32, and correspondingly, the second delivery mechanism includes a third driving member 33 and a second clamping assembly 34. In this embodiment, the first driving member 31 is arranged on the main body 1, and the first clamping assembly 32 is arranged at the power output end of the first driving member 31. The third driving member 33 and the above-mentioned support column 14 are arranged on the same mounting base, and the second clamping assembly 34 is arranged at the power output end of the third driving member 33. As a preferred embodiment, a mounting platform 106 is arranged on the side wall of the reaction cylinder 12, the first driving member 31 is fixedly mounted on the mounting platform 106, and the third driving member 33 is fixedly arranged on the ground. Among them, the first driving member 31 and the third driving member 33 are both arranged as hydraulic cylinders.

[0100] It should be further understood that the first driving member 31 and the third driving member 33 are configured to move synchronously. This configuration can enable the first electrode rod 21 and the second electrode rod 22 to move closer to or farther away from each other, which helps to further improve the control accuracy of the delivery mechanism over the discharge distance between the first electrode rod 21 and the second electrode rod 22, thereby improving the accuracy of its temperature control over the working gas, which can further improve the use effect of the heat source supply device.

[0101] In this embodiment, since the first clamping assembly 32 and the second clamping assembly 34 have the same structure, the first clamping assembly 32 is taken as an example for description. The first clamping assembly 32 includes a connecting plate 321, a first clamping member 322, and a second clamping member 323, wherein the connecting plate 321 is fixedly arranged at the power output end of the first driving member 31. The first clamping member 322 is arranged on the connecting plate 321, and the second clamping member 323 is movably arranged on the connecting plate 321. The second clamping member 323 is arranged to be movable, so that the second clamping member 323 can cooperate with the first clamping member 322 to achieve clamping and loosening of the first electrode rod 21.

[0102] Specifically, the connecting plate 321 is fixedly connected with the power output end of the first driving member 31 by bolts, a fixing frame 325 is connected to the first connecting plate 321 by bolts, and the fixing frame 325 is installed with the first clamping member 322 and the second driving member 324, wherein the output end of the second driving member 324 is fixedly connected with the second clamping member 323 by the connecting frame 326, and at this time, a return spring 327 is arranged between the fixing frame 325 and the connecting frame 326 to cooperate with the second driving member 324 to ensure the clamping effect of the first clamping assembly 32 on the second clamping member 323. Specifically, the second driving member 324 is set as a cylinder. By setting the second driving member 324 to drive the second clamping member 323 to move, the distance between the first clamping member 322 and the second clamping member 323 can be adjusted, thereby facilitating the clamping and fixing of the first electrode rod 21 by the first clamping assembly 32, and ensuring that the first electrode rod 21 will not move during actual use.

[0103] Here, it should be noted that, in addition to fixing the first clamping member 322 on the connecting plate 321, the first clamping member 322 can also be movably set on the connecting plate 321, and in this case, another cylinder needs to be set on the connecting plate 321, and the two cylinders move synchronously to ensure that the clamping position of the first electrode rod 21 is fixed. Of course, the first clamping member 322 is fixedly set on the connecting plate 321, which helps to determine the clamping position of the first electrode rod 21, and the clamping effect of the first electrode rod 21 is optimal.

[0104] In addition, the first clamping member 322 has a first action surface abutting against the first electrode rod 21, and the second clamping member 323 has a second action surface abutting against the first electrode rod 21. Preferably, both the first action surface and the second action surface are configured as arc surfaces, and can be closely connected with the circumference of the first electrode rod 21. Such a configuration helps to reduce the damage of the first clamping assembly 32 to the first electrode rod 21, and helps to ensure the stability of clamping.

[0105] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, two sealing components are provided on the main body 1, and the first electrode rod 21 passes through one of the two sealing components, and the second electrode rod 22 passes through the other of the two sealing components. In this embodiment, the working gas outputted from the air inlet component 5 to the inside of the main body 1 needs to be mixed with the plasma gas between the first working end and the second working end and then outputted from the gas outlet 102. Since the first electrode rod 21 and the second electrode rod 22 are both provided on the main body 1, it is necessary to provide a sealing component at the connection between the first electrode rod 21 and / or the second electrode rod 22 and the main body 1 to prevent the air flow in the main body 1 from escaping, reduce the loss of high-temperature gas, and ensure the heat conversion rate of the heat source supply device. Preferably, the two sealing components are respectively provided at the top and bottom of the reaction cylinder 12. In addition, the provision of the sealing component also helps to prevent external gas or substances from entering the heating channel, thereby improving the safety of the main body 1 when in use.

[0106] At this time, for the convenience of description, the sealing assembly located at the top of the reaction tube 12 is taken as an example for description. The sealing assembly includes a first connecting seat 41, a protective member 42, a second connecting seat 43 and a sealing member 44. Among them, the first connecting seat 41 is arranged on the reaction tube 12, and the first electrode rod 21 is passed through the first connecting seat 41. Specifically, a mounting port is opened on the reaction tube 12, the first connecting seat 41 is welded on the mounting port, and the first electrode rod 21 passes through the first connecting seat 41. Combined with Figure 6 As shown, a baffle 411 is provided on the first connection seat 41, the protective member 42 is provided inside the first connection seat 41 and one end thereof abuts against the baffle, and at this time, the second connection seat 43 is fixedly connected to the first connection seat 41 and abuts against the other end of the protective member 42 to fix the protective member 42 inside the first connection seat 41. In this embodiment, the protective member 42 is an electrode insulating sleeve and is located between the inner wall of the first connection seat 41 and the circumferential surface of the first electrode rod 21, that is, the protective member 42 is sleeved on the first electrode rod 21, which helps to prevent direct current from flowing to the main body 1 through the first electrode rod 21, and helps to improve the safety of the main body 1 in use.

[0107] In this embodiment, the second connection seat 43 is connected to the first connection seat 41 by bolts, and a connecting member 45 is provided between the second connection seat 43 and the first connection seat 41. The connection member can effectively ensure the sealing of the connection between the second connection seat 43 and the first connection seat 41, which helps to reduce the loss of gas. The connecting member can be set as a rubber member.

[0108] Still Figure 6As shown, the second connection seat 43 is sleeved on the first electrode rod 21. Specifically, the second connection seat 43 includes a seat body 431 and a sealing cover 433. The seat body 431 is used to be fixedly connected to the first connection seat 41, and the first end of the seat body 431 abuts against the protective member 42, and the second end of the seat body 431 is provided with a sealing cover 433. At the same time, a support plate 432 is provided inside the seat body 431, and at this time, the support plate 432, the inner wall of the seat body 431, and the sealing cover 433 cooperate to form an accommodating space, and the above-mentioned sealing member 44 is fixedly provided in the accommodating space and abuts against the peripheral surface of the first electrode rod 21. In this embodiment, the sealing member 44 includes a plurality of sleeves 441 of different lengths and a high-temperature resistant skeleton oil seal 442. The two ends of the sleeve 441 are respectively in contact with the support plate 432 and the sealing cover 433, and a high-temperature resistant skeleton oil seal 442 is arranged between two adjacent sleeves 441. Such an arrangement helps to improve the sealing effect of the sealing assembly, reduce gas loss, and ensure the feasibility of the insertion and movement of the first electrode rod 21.

[0109] In addition, a cooling sleeve 434 is provided on the outer peripheral surface of the seat body 431. The cooling sleeve 434 is welded to the outer side of the seat body 431 and cooperates with the seat body 431 to form a cooling cavity. At the same time, an inlet and an outlet connected to the cooling cavity are provided on the cooling sleeve 434 for inputting and outputting cooling liquid. The provision of the cooling sleeve 434 helps to reduce the temperature of the sealing component, thereby further improving the safety of the heat source supply device.

[0110] like Fig.11 As shown, the first electrode rod and / or the second electrode rod is configured as a plurality of electrode units, and two adjacent electrode units are connected by threads. The first electrode rod or the second electrode rod is configured as a plurality of electrode units screwed end to end, which helps to ensure that the first electrode rod or the second electrode rod has a sufficient length for use. In this embodiment, the first electrode rod or the second electrode rod is configured as three electrode units, and each electrode unit is configured as a graphite electrode. Of course, the electrode unit can also be configured as an electrode of other materials. With such a configuration, the plasma generating assembly can cooperate with the delivery mechanism to further ensure that the continuous delivery of the electrode unit can be implemented, thereby helping to increase the service life of the electrode unit in the heat source supply device, such as the first electrode rod 21 and the second electrode rod 22 can be used continuously for up to 30,000 hours (can work continuously for more than 3 years).

[0111] At this time, the number of the above-mentioned plasma generating components is multiple, and the multiple plasma generating components can be arranged on the main body at intervals along the extending direction of the heating channel. Figure 5As shown, multiple electrode assemblies can be spaced apart along the extension direction of the heating channel and in the horizontal direction, which can further increase the power usage of the heat source supply device from the existing 2MW to more than 30MW. At this time, the temperature of the target gas output by the heat source supply device can be adjusted from 500 to 3000 degrees (and can be increased to a higher temperature required for industrial production), which helps to further improve the thermal conversion efficiency of the heat source supply device and improve the utilization of resources.

[0112] Still Figure 1-Figure 3 As shown, the heat source supply device also includes a detection component, which includes a first detection component 61 and a second detection component 62, wherein the first detection component 61 is used to detect the temperature between the first working end and the second working end. The second detection component 62 is used to detect the temperature and / or wind speed of the air outlet 102. In this embodiment, the first detection component 61 is a thermometer, the first detection component 61 is arranged on the reaction tube 12, and is located on the side of the first working end and / or the second working end close to the air outlet 102, and the second detection component 62 is arranged as a temperature sensor and a wind speed sensor, and both are arranged on the second end cover 13. By arranging the first detection component 61 and the second detection component 62, the temperature of the working gas between the first working end and the second working end and the temperature of the working gas at the air outlet 102 can be effectively monitored, so as to cooperate with the delivery mechanism to control the discharge distance between the first working end and the second working end, and then regulate the output temperature of the working gas.

[0113] At this time, an observation port is provided on the circumference of the reaction tube 12, and a sight glass 64 is provided on the observation port so as to be able to observe the discharge distance between the first electrode rod 21 and the second electrode rod 22. As a preferred embodiment, a scale is provided on the sight glass 64 so as to improve the accuracy of observation and provide a data basis for adjusting the discharge distance. In addition, the above-mentioned detection component also includes a third detection member 63, which can be set as a temperature sensor to detect the temperature of the main body 1, so as to cooperate with the water jacket structure and cooling component described below to ensure the safety of the heat source supply device.

[0114] Still Figure 1As shown, the air intake assembly 5 includes a first fan 51, an air intake portion 52 and an air outlet portion 53, wherein the air intake portion 52 is arranged at the input end of the first fan 51, and the air intake portion 52 is used to communicate with the air outlet 102 of the main body 1, and at this time, the working gas output by the air outlet 102 and used many times can be introduced into the first fan 51, and re-enter the main body 1 under the action of the first fan 51, so as to realize the recycling of the working gas, which helps to further reduce the emission of carbon dioxide. At the same time, the above-mentioned air outlet portion 53 is arranged at the output end of the first fan 51 and is fixedly connected to the first end cover 11 of the main body 1. In this embodiment, the working gas is air. Preferably, the output power of the first fan 51 is adjustable, and the input wind speed of the working gas can be adjusted according to the feedback of the wind speed sensor in the second detection member 62.

[0115] Here, it should be noted that in addition to being set to air, the working gas can also be set to one or a mixed gas of nitrogen, carbon dioxide and inert gas to ensure that the working gas meets the set temperature after mixing with the plasma gas, and the set temperature range is 500℃~1000℃.

[0116] like Figure 6 As shown, the heat source supply device also includes a constraint mechanism to effectively constrain the working gas in the heating channel 103, so as to avoid the occurrence of airflow or heat dissipation, which helps to further improve the heat conversion efficiency of the heat source supply device. In this embodiment, the constraint mechanism includes an air supply component and an air supply component. There are two air supply components, which are respectively arranged on the first end cover 11 and the second end cover 13.

[0117] Specifically, Figure 1 , Figure 3 and Figure 6 As shown, the air supply assembly includes an air inlet pipe 73, a connecting pipe 72 and an air supply member 71. There are multiple air inlet pipes 73, and the output end of each air inlet pipe 73 is connected to a connecting pipe 72. The connecting pipe 72 extends to the interior of the main body 1 and is connected to the air supply member 71. At this time, the air supply member 71 is arranged along the circumference of the heating channel 103, and the air supply member 71 has an air supply port arranged along the extension direction of the heating channel 103, that is, the air supply member 71 has an air supply port arranged horizontally. In this embodiment, the number of air inlet pipes 73 is six, and correspondingly, the number of connecting pipes 72 is six. Combined with Figure 6 and Figure 8 As shown, the air supply member 71 is an integrated structure, and the air supply port of the air supply member 71 is arranged along the circumference of the heating channel 103 .

[0118] It should be understood that the heat source supply device has two air supply components, and the air supply parts 71 of the two air supply components are respectively arranged at the two ends of the heating channel 103, and the air supply ports of the two air supply parts 71 are arranged oppositely. When the air supply component inputs working gas to the air supply component, the working gas output by the air supply part 71 can form a high-pressure airflow in the circumferential direction of the heating channel 103, which helps to constrain the working gas mixed with plasma state to the central position of the heating channel 103, thereby limiting the flow direction of the mixed gas in the heating channel 103 and reducing heat loss. At the same time, it can also prevent the inner wall of the main body 1 from being eroded by high-temperature gas, ensure that the inner wall of the main body 1 is not burned, and improve the service life and safety of the equipment. Moreover, the constraint mechanism can also conduct heat to the working gas input by the air intake component 5, and quickly neutralize and regulate the temperature of the working gas. At this time, the constraint mechanism can cooperate with the delivery mechanism, the air intake component 5 and the detection component to achieve the required temperature and wind speed when the working gas flows out in the shortest time.

[0119] In addition, the number of air supply components 71 can also be set to multiple, and the multiple air supply components 71 are arranged in layers outward with the heating channel 103 as the center, so as to be able to perform multi-layer constraints on the gas in the heating channel 103, thereby helping to further improve the constraint effect on the working gas. Of course, in addition to this, the air supply component 71 can also be set as a split structure, that is, the air supply component 71 includes multiple air outlet pipes, and each air outlet pipe is connected to an air inlet pipe 73 through a connecting pipe 72, and the multiple air outlet pipes are arranged at intervals along the circumference of the heating channel 103. Such an arrangement helps to reduce the processing cost of the air supply component and improve the assembly efficiency of the air supply component. Fig. 9 and Fig.10 As shown, in this embodiment, three air supply members 71 are provided, and the three air supply members 71 extend outward from the heating channel 103 as the center and are arranged at intervals, so as to achieve multi-layer confinement of the gas in the heating channel 103. At the same time, each air supply member 71 is provided with six air outlet pipes, which not only helps to reduce processing costs but also helps to improve the confinement effect.

[0120] In this embodiment, the air supply assembly includes a second fan 77, a connecting main pipe 74 and a control valve 76. Among them, the second fan 77 is connected to multiple air inlet pipes 73 through the connecting main pipe 74. At the same time, a connecting branch pipe 75 is provided between the connecting main pipe 74 and the air inlet pipe 73, and a control valve 76 is provided on the connecting branch pipe 75, and the opening and closing degree of the control valve 76 can be used to control the wind speed of the air supply port. It should be further understood that when the number of air supply parts 71 is three, each air supply part 71 is individually connected to multiple air inlets 101, and multiple air inlets 101 are individually connected to the connecting main pipe 74, and at this time, by setting control valves 76 with different openings, multiple constraint channels can be formed in the circumferential direction of the conveying pipeline, and the wind pressure and wind speed of each constraint channel are different, which helps to further improve the use effect of the heat source supply device.

[0121] Here, it should be noted that the air supply assembly and the air delivery assembly cooperate to input the working gas into the main body 1, and at this time, the working gas and the working gas input into the main body 1 by the air intake assembly are the same type of gas.

[0122] like Figure 6 , Figure 8 , Fig. 9 and Fig.10 , a refractory material 8 is arranged on the inner wall of the main body 1 to protect the inner wall of the main body 1 and prevent the working gas from burning the main body 1 due to excessive temperature. At the same time, it can also reduce the heat loss inside the main body 1 and improve the utilization efficiency. In this embodiment, the refractory material 8 is arranged inside the main body 1 by masonry. Since the main body 1 includes a reaction tube 12, a first end cover 11 and a second end cover 13, the refractory material 8 can be cast separately first, and then the refractory material 8 is arranged inside the main body 1 by connecting and assembling. As a preferred implementation method, the refractory material 8 is a high-temperature resistant material or a composite of multiple high-temperature resistant materials. Specifically, the refractory material 8 is set to a graphite refractory material or a corundum brick or a high-alumina brick refractory material.

[0123] At this time, a cooling assembly is provided on the main body 1, and the cooling assembly includes a coolant inlet 91 and a coolant outlet 93 provided on the reaction tube 12, and a cooling channel 92 is provided between the coolant inlet 91 and the coolant outlet 93, and the cooling channel 92 is provided inside the refractory material 8, specifically, a coolant inlet 91 is provided at the top of the main body 1, and a coolant outlet 93 is provided at the bottom of the main body 1, and at the same time, the cooling channel 92 is provided inside the refractory material 8, and is arranged around the heating channel 103 as the center, which helps to cool down the heat conducted from the inner wall of the refractory material 8, thereby preventing the temperature of the shell of the main body 1 from exceeding the standard, playing a role of cooling protection, and at the same time, the hot water in the coil can also be circulated and reused. As a preferred embodiment, the cooling channel 92 is spiraled into a spiral structure and is arranged around the heating channel 103 as the center to improve the cooling effect of the cooling channel 92. In this embodiment, the material of the cooling channel 92 can be selected from a copper tube or a 304 stainless steel tube, a 310S stainless steel tube, to enhance the thermal conductivity and service life of the cooling channel 92, and is not easy to produce rust.

[0124] In addition, in order to control the surface temperature of the main body 1, a water jacket structure is provided on the end cover. Specifically, in this embodiment, the main body 1 has an inner cylinder 104 and an outer cylinder 105, and a cooling space is formed between the inner cylinder 104 and the outer cylinder 105. The cooling space is used for the circulation of the cooling liquid. Figure 6 As shown, a liquid inlet and a liquid outlet are provided on the outer cylinder 105, the liquid inlet is used to receive normal temperature water, and the liquid outlet is used to output hot water, and the hot water can be recycled again, and the liquid inlet amount of the liquid inlet and the liquid outlet amount of the liquid outlet can be regulated according to the temperature of the main body 1 detected by the third detection member 63. The setting of the water jacket structure helps to further improve the safety of the heat source supply device.

[0125] It should be further understood that the heat source supply device also includes a controller, such as Fig.12 As shown, the controller is electrically connected to the first detection member 61, the second detection member 62 and the third detection member 63 of the detection assembly, and the controller is also simultaneously connected to the first motor, the second motor, the first driving member 31 of the delivery mechanism, the third driving member 33 of the delivery mechanism, the second driving member 324 of the first clamping assembly 32, the fourth driving member of the second clamping assembly 34, the first water pump connected to the coolant inlet, the second water pump connected to the liquid inlet, and the current supply member. The heat source supply device can accurately control the working gas output by the heat source supply device through the linkage control of the controller, so as to output the working gas with a set temperature and a set wind speed, and help to improve the heat conversion efficiency of the heat source supply device.

[0126] In actual use, the controller first starts the first fan 51 and introduces working gas into the main body 1, then controls the first water pump and the second water pump to start, and the first driving member 31 and the third driving member 33 to work, so that the first electrode rod 21 and the second electrode rod 22 reach the specified position, then starts the second fan 77 to blow working gas for confining the working gas into the main body 1, and finally, starts the current supply member to work.

[0127] Then, the controller can adjust the first fan 51, the second fan 77, the current supply member, the first driving member 31 and the third driving member 33 according to the feedback of the first detection member 61 and the second detection member 62. At the same time, the controller can adjust the first water pump and the second water pump according to the feedback of the third detection member 63.

[0128] When the first electrode rod 21 and the second electrode rod 22 need to be replaced, or the clamping position of the clamping assembly on the first electrode rod 21 or the second electrode rod 22 needs to be adjusted, the controller controls the first driving member 31, the third driving member 33, the first driving member 324 and the fourth driving member to operate.

[0129] The heat source supply device of the present application, by supplying direct current to the first electrode rod 21 and the second electrode rod 22, can convert the gas between the first electrode rod 21 and the second electrode rod 22 into a plasma state, and mix it with the working gas input from the air inlet 101 and output it from the air outlet 102, which helps to generate high-temperature gas by ionizing the working gas to replace the high-temperature flue gas generated by the combustion of fossil fuels, provide the heat source required for production for industrial kilns, and help eliminate environmental pollution caused by fuel problems. As a heat source for industrial kilns, the heat source supply device of the present application reduces the demand for fossil fuels, thereby reducing carbon emissions at the source, which is of significant significance for achieving carbon neutrality goals in industrial production processes.

[0130] At the same time, the present application also helps to improve the production efficiency of the working gas and ensure the heat conversion efficiency of the heat source supply device by setting a constraint mechanism and a sealing component, so that compared with the prior art, the heat conversion efficiency of the heat source supply device can reach 75% to 80%, thereby accelerating the heating speed, shortening the production process, and improving production efficiency. Moreover, the setting of the constraint mechanism can cooperate with the refractory material 8 to prevent the inner wall of the main body 1 from being eroded by the high-temperature gas, which helps to ensure that the inner wall of the main body 1 is not burned, and improves the service life and safety of the equipment. In addition, the working gas output by the constraint mechanism can play a role in heat conduction and neutralization of the working gas, thereby improving the precise control of the heat source supply device.

[0131] In addition, the heat source supply device of the present application can increase the existing 2MW to more than 30MW, and the temperature of the working gas outputted by it can be adjusted from 500 to 3000 degrees (and can be increased to a higher temperature required for industrial production). Therefore, the heat source supply device has the characteristics of high power and high heating temperature. At the same time, the heat source supply device can adjust the temperature and flow of the high-temperature gas in real time, so as to provide part or all of the heat source for the industrial kiln to meet the process and production requirements of the industrial kiln, and the heat source supply device can achieve continuous and stable operation, such as the first electrode rod 21 and the second electrode rod 22 can be used continuously for up to 20,000-30,000 hours (can work continuously for more than 3 years). In addition, the gas source selection range of the working gas is wide (oxidizing or reducing gas, and one or more of inert gas).

[0132] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
