[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 9 As shown, a waste heat recovery device for a steam cabinet according to an embodiment of the present invention comprises: a waste heat recovery box 1, a heat exchanger tube body 6 is arranged inside the waste heat recovery box 1, three heat exchanger tube bodies 6 are arranged and rotatably arranged inside the waste heat recovery box 1; an air guide component 7, the air guide component 7 is arranged on both sides of the top end and the bottom end of the heat exchanger tube body 6, and the air guide component 7 is used to blow smoke to the outside of the heat exchanger tube body 6; an air inlet component 4, the air inlet component 4 is arranged on the air guide component 7, and is used to introduce smoke into the air guide component 7.

[0032] When the flue gas blows horizontally through the heat exchanger tube 6, the smoke-receiving surface of the heat exchanger tube 6 cannot fully contact the flue gas, resulting in the flue gas being unable to be fully heated. This will not only make the heat exchanger tube 6 unable to fully absorb the heat in the flue gas, resulting in poor waste heat recovery and energy waste, but also the uneven heating of the heat exchanger tube 6 will lead to a large temperature difference between the various parts of the tube, which is easy to cause thermal stress, and may cause problems such as deformation and rupture of the tube. As a result, during long-term operation, the heat exchanger tube 6 will crack due to excessive local thermal stress, resulting in leakage.

[0033] The air bleed component 4 guides the flue gas into the air guide component 7, and the air guide component 7 is used to evenly guide the flue gas to the outside of the heat exchanger tube body 6. The flue gas is blown to the four sides of the heat exchanger tube body 6, so that the flue gas is fully in contact with the heat exchanger tube body 6, thereby ensuring that the heat exchanger tube body 6 can evenly absorb the waste heat of the flue gas. The uniform heating of the heat exchanger tube body 6 can not only ensure that the heat exchanger tube body 6 fully absorbs the heat of the flue gas and improves the waste heat recovery effect, but also prevent the problem that when the flue gas blows to the heat exchanger tube body 6, the smoke-receiving surface of the heat exchanger tube body 6 cannot be fully heated, resulting in a reduction in the waste heat recovery effect. It can also prevent uneven heating from causing a large temperature difference between the various parts of the heat exchanger tube body 6, causing thermal stress, causing deformation and rupture of the tube body, and causing the heat exchanger tube body 6 to crack due to excessive local thermal stress during long-term operation, and leakage occurs.

[0034] like Figures 1 to 9 As shown, the air guide component 7 includes: a smoke box 71, which is arranged on both sides of the top and bottom ends of the heat exchanger tube body 6, and the smoke box 71 is fixed to the inside of the waste heat recovery box 1, and the smoke box 71 is symmetrically distributed at the top and bottom ends of the center line of the heat exchanger tube body 6; an exhaust head 72, the exhaust head 72 is arranged at the end of the smoke box 71 facing the heat exchanger tube body 6, the exhaust head 72 is connected to the smoke box 71 through a flexible pipe, and the number of smoke boxes 71 and exhaust heads 72 is the same; a shaft 73, the shaft 73 is fixed to both sides of the exhaust head 72, and the exhaust head 72 is rotatably arranged in the inside of the waste heat recovery box 1 through the shaft 73, and the air guide component 7 also includes: a driven gear 74, the driven gear 74 is fixed to the outside of the shaft 73; a pneumatic Wheel 79, the pneumatic wheel 79 is rotatably arranged inside the flue gas box 71; half-toothed gear 78, the half-toothed gear 78 is arranged on both sides of the flue gas box 71, and the half-toothed gear 78 is located at one end of the driven gear 74, and the rotating shafts on both sides of the pneumatic wheel 79 protrude from both sides of the flue gas box 71 and are fixedly connected to the half-toothed gear 78; shaft body 2 76, shaft body 2 76 is fixed on one side of the half-toothed gear 78, and is located at one end of shaft body 1 73; built-in groove 1 75, built-in groove 1 75 is opened on both sides of the inside of the waste heat recovery box 1, and corresponds to the position of shaft body 1 73, and shaft body 1 73 is rotatably arranged in the built-in groove 1 75; torsion spring 1 77, torsion spring 1 77 is fixed inside the built-in groove 1 75, and the inner side of torsion spring 1 77 is fixed on the outer wall of shaft body 1 73.

[0035] Correctly install the waste heat recovery device near the exhaust gas outlet of the steam cabinet, connect it to the exhaust gas outlet of the steam cabinet using the connecting flange 2, fill the medium into the heat exchanger tube body 6, and connect the circulating pump to the connecting pipe 3, use the circulating pump to make the medium circulate in the heat exchanger tube body 6, and use the air bleed component 4 to continuously blow the flue gas into the air guide component 7;

[0036] The smoke is introduced into the smoke box 71 by the air bleed assembly 4, and the smoke is continuously blown toward the wind-inducing blades at one end of the pneumatic wheel 79 in the smoke box 71, so that the pneumatic wheel 79 continuously rotates inside the smoke box 71, and the pneumatic wheel 79 drives the second shaft 76 and the half-toothed gear 78 outside thereof to rotate;

[0037] When the half-toothed gear 78 rotates to a position where it meshes with the driven gear 74, it drives the driven gear 74 and the shaft 1 73 to rotate;

[0038] The rotating shaft 73 drives the exhaust head 72 to rotate and change its own angle. The rotation direction of the exhaust head 72 is as follows: Fig. 9 As shown in the direction of the middle arrow, the rotating shaft 73 drives the torsion spring 77 to twist and deform;

[0039] When the half-toothed gear 78 rotates to a position where it is not meshed with the driven gear 74, it does not drive the driven gear 74 and the shaft 1 73 to rotate;

[0040] The torsion spring 77 uses its own elastic force to drive the shaft 73 toward Fig. 9 Rotate in the opposite direction as indicated by the arrow in the middle and return to the initial state;

[0041] Four exhaust heads 72 are arranged on both sides of the top and bottom of each heat exchanger tube body 6. The exhaust heads 72 at the four positions swing back and forth to evenly spray the flue gas around the heat exchanger tube body 6, so that the flue gas fully contacts the heat exchanger tube body 6, thereby ensuring that the heat exchanger tube body 6 can evenly absorb the waste heat of the flue gas, thereby ensuring that the heat exchanger tube body 6 fully absorbs the heat of the flue gas, improving the waste heat recovery effect, and preventing the problem that when the flue gas blows toward the heat exchanger tube body 6, the smoke-receiving surface of the heat exchanger tube body 6 cannot be fully heated, resulting in a reduced waste heat recovery effect;

[0042] It should be noted here that the smoke exhaust port can be opened at the front or back of the waste heat recovery box 1 to discharge the smoke after heat exchange, which is not shown in the figure.

[0043] like Figures 1 to 9As shown, the air bleed assembly 4 includes: an air bleed pipe 41, which is installed at the top and bottom of the waste heat recovery box 1, and the number of the air bleed pipes 41 is the same as the number of the smoke box 71; a connecting flange 2, which is fixed on the air bleed pipe 41 and is used to connect the air bleed pipe 41 with the smoke duct. The air bleed assembly 4 also includes: a connecting pipe 43, which is arranged at the top and bottom ends inside the waste heat recovery box 1, and is located on both sides of the top and bottom ends of the heat exchanger tube body 6, the number of the connecting pipes 43 is the same as the number of the air bleed pipe 41, and the connecting pipe 43 is connected to the air bleed pipe 41; an air bleed pipe 42, which is arranged between the connecting pipe 43 and the smoke box 71, and the air bleed pipe 42 is connected to the connecting pipe 43 and the smoke box 71, and the air outlet of the air bleed pipe 42 faces the windward blade position of the wind wheel 79.

[0044] When the smoke inlet is larger, more smoke can enter the pipe in the same time, while the smoke outlet is smaller, which limits the flow rate of smoke exhaust, so that the speed of smoke increases. The smoke inlet of the air duct 1 41 and the air duct 2 42 is larger than the smoke outlet.

[0045] The connecting flange 2 is connected to the exhaust gas outlet of the steam cabinet, and the smoke is introduced into the connecting pipe 43 through the air duct 1 41, and then continuously injected into the smoke box 71 through the air duct 2 42. The smoke passes through the air duct 1 41, and the smoke exhaust speed is increased by the action of the air duct 1 41. After that, the smoke passes through the air duct 2 42, and the smoke exhaust speed is increased by the action of the air duct 2 42, so that the smoke can efficiently blow the wind-inducing blades at one end of the pneumatic wheel 79 in the smoke box 71 to rotate;

[0046] It should be noted here that in order to increase the speed at which smoke enters the smoke box 71 and enable the pneumatic wheel 79 to rotate better, an exhaust fan can be installed at the position of the air duct 41 to increase the speed at which smoke enters. The exhaust fan is used to speed up the speed at which smoke enters, and the design of the air duct 41 and the air duct 42 is coordinated so that the smoke can better blow the pneumatic wheel 79 to rotate, thereby better driving the shaft 2 76 to rotate.

[0047] like Figures 1 to 9 As shown, the device also includes: a driving component 5, which is arranged on one side of the waste heat recovery box 1, and is used to drive the heat exchanger tube body 6 to rotate; a connecting pipe 3, which is arranged on both sides of the heat exchanger tube body 6, and is used to introduce the medium into the heat exchanger tube body 6 for heat exchange and discharge; a connecting component 8, which is arranged on both sides of the inside of the waste heat recovery box 1, and is used to improve the smoothness of the rotation of the heat exchanger tube body 6 and the exhaust head 72, and the connecting component 8 is used to ensure the connection between the connecting pipe 3 and the heat exchanger tube body 6; a cleaning brush 9, which is arranged at the middle position of the top of the heat exchanger tube body 6, and the heat exchanger tube body 6 is fixed inside the waste heat recovery box 1.

[0048] The driving assembly 5 includes: a pulley 1 53, which is arranged on one side of the waste heat recovery box 1 and fixed to the outside of one side of the heat exchanger tube body 6; a pulley 2 54, which is arranged at the rear end of one side of the waste heat recovery box 1 and is on the same horizontal plane as the pulley 1 53, and the pulley 1 53 and the pulley 2 54 are connected by a belt. The driving assembly 5 also includes: a bracket 52, which is arranged on the outside of the pulley 2 54 and fixed to the side wall of the waste heat recovery box 1; a motor 51, which is installed on the bracket 52, and the rotating shaft of the motor 51 extends to the inside of the bracket 52 and is fixedly connected to one side of the pulley 2 54; a cleaning brush 9, which is arranged on the top of the heat exchanger tube body 6 and fixed to the inside of the waste heat recovery box 1.

[0049] When the waste heat is recovered, the motor 51 is started, and the motor 51 drives the pulley 2 54 to rotate, and the belt drives the pulley 1 53 to rotate, and the rotating pulley 1 53 drives the heat exchanger tube 6 to rotate inside the waste heat recovery box 1, and the rotating heat exchanger tube 6 cooperates with the four exhaust heads 72 located around the heat exchanger tube 6 to continuously blow the flue gas to the surroundings of the heat exchanger tube 6, which can better make the heat exchanger tube 6 contact with the flue gas, thereby improving the heat absorption effect of the heat exchanger tube 6, so that the heat exchanger tube 6 can absorb heat more evenly;

[0050] The cleaning brush 9 is arranged on the top of the heat exchanger tube body 6. When the heat exchanger tube body 6 rotates, the cleaning brush 9 can clean the surface of the heat exchanger tube body 6. By cleaning the surface of the heat exchanger tube body 6, dirt or dust attached to the surface of the heat exchanger tube body 6 is removed, thereby preventing excessive dirt or dust mixed in the flue gas from being attached to the outside of the heat exchanger tube body 6, forming a heat insulation layer on the surface of the heat exchanger tube body 6, and hindering the problem of heat transfer.

[0051] like Figures 1 to 9 As shown, the connecting component 8 includes: a built-in groove 82, which is arranged on both sides of the heat exchanger tube body 6, and the built-in groove 82 is opened on both sides of the waste heat recovery box 1; a bearing 83, which is fixed to the outside of both sides of the heat exchanger tube body 6, and the bearing 83 is placed inside the built-in groove 82, and the outer wall of the bearing 83 is fixedly connected to the inner wall of the built-in groove 82; a built-in groove 85, which is arranged on both sides of the flue gas box 71, and the shaft body 76 is rotatably arranged inside the built-in groove 85; a bearing 84, which is fixed to the outside of the shaft body 76, and the bearing 84 is placed inside the built-in groove 85, and the outer wall of the bearing 84 is fixedly connected to the inner wall of the built-in groove 85. The connecting component 8 also includes: a bearing 81, which is fixed to the outside of the connecting pipe 3, and the bearing 81 is placed inside both sides of the heat exchanger tube body 6, and the outer wall of the bearing 81 is fixedly connected to the inner wall of the heat exchanger tube body 6.

[0052] The bearing 3 84 is installed inside the built-in groove 3 85 and acts on the shaft 2 76. When the wind wheel 79 is driven by the smoke to rotate and drive the shaft 2 76 and the half-toothed gear 78 to rotate, the bearing 3 84 can improve the smoothness of the rotation of the wind wheel 79, so that the wind wheel 79 can be blown more easily.

[0053] The bearing 1 81 is installed between the connecting pipe 3 and the heat exchanger tube body 6. When the heat exchanger tube body 6 rotates, the bearing 1 81 can prevent the connecting pipe 3 from rotating with the heat exchanger tube body 6, thereby ensuring the connection between the circulating pump and the heat exchanger tube body 6 through the connecting pipe 3, and preventing the connecting pipe 3 from rotating with the heat exchanger tube body 6 and affecting the connection stability.

[0054] The second bearing 83 is installed in the second built-in groove 82 . The second bearing 83 acts on both sides of the heat exchanger tube 6 . The second bearing 83 can improve the rotation smoothness of the heat exchanger tube 6 and ensure the rotation effect of the heat exchanger tube 6 inside the waste heat recovery box 1 .
