Description

Technical Field

[0001] The utility model relates to the technical field of energy conservation and environmental protection, and particularly relates to a flue gas waste heat recovery and reuse device. Background Technique

[0002] The flue gas waste heat recovery and reuse device is mainly used for recovering the heat in the flue gas discharged during industrial production processes to reduce energy waste and environmental pollution. The flue gas waste heat recovery technology is widely applied to various devices such as boilers, kilns, and smelting furnaces. By recovering the flue gas waste heat, energy consumption can be reduced, the efficiency of the devices can be improved, and at the same time, greenhouse gas emissions can be reduced, which has significant economic and environmental benefits.

[0003] During the use of the flue gas waste heat recovery and reuse device, the flue gas is usually injected into the interior of the conveying pipe, and then water is added to the interior of the cooling box. During the process of the flue gas flowing inside the conveying pipe, the water will absorb the waste heat in the flue gas through the conveying pipe, and the flue gas after the waste heat is absorbed is finally discharged through the exhaust pipe.

[0004] During the operation of the existing flue gas waste heat recovery and reuse devices, although the waste heat in the flue gas can be recovered by water, the contact area between the water and the flue gas is limited, resulting in a relatively slow absorption rate of the waste heat in the flue gas by the water, reducing the recovery efficiency of the flue gas waste heat. Some flue gas waste heat recovery and reuse devices rotate the stirring blades at a specific height inside the cooling box through multiple driving devices to stir the water in the cooling box, thereby increasing the contact area between the water and the flue gas to a certain extent. However, there are problems such as a single stirring direction of the water and a limited specific stirring area, which restricts the water flow direction. Subsequently, there will also be a problem of a small contact amount between the water and the flue gas and too low heat exchange and recovery efficiency. For this reason, we propose a flue gas waste heat recovery and reuse device. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a flue gas waste heat recovery and reuse device. The water body can flow in two dimensions, so that the water body can exchange heat and rise in temperature more comprehensively and in a larger amount, improving the recovery efficiency of flue gas waste heat, and effectively solving the problems in the background technique.

The left end of the exhaust pipe is communicated with the connecting groove formed on the right side of the outer arc surface of the conveying pipe. Both the air inlet valve and the exhaust valve are located outside the box body. During the process of the flue gas flowing inside the conveying pipe, the water will absorb the waste heat in the flue gas for preliminary heating.

[0013] Furthermore, it also includes a protective cover, a sliding column, an adjusting plate, a cross bar, an output rod, a cam, and bevel gears. The protective cover is arranged in the middle of the upper end of the box body. The output rod is rotatably connected to the middle of the left wall of the protective cover.

[0019] 2. During the rotation of the output rod, the output rod can drive the cam to rotate at the same time. When the contact point between the cam and the adjusting plate changes from the center to the far center, the cam drives the sliding column to move downward through the adjusting plate, and the spring contracts. The sliding column drives the mounting ring to move downward through the cross bar, and the mounting ring drives the vertical rod to move downward. When the contact point between the cam and the adjusting plate changes from the far center to the center, the thrust generated by the extension of the spring drives the sliding column to move upward and reset through the adjusting plate. During the upward movement of the sliding column, the sliding column drives the mounting ring to move upward and reset through the cross bar, and the mounting ring drives the vertical rod to move upward, so that the stirring fan blades can drive the water to continuously tumble through the lifting plate while stirring the water, giving the water body a circumferential stirring and vertical turning force, and the water body can flow in two dimensions, so that the water body can exchange heat and heat up more comprehensively and in a larger amount, improving the efficiency of flue gas waste heat recovery and reuse.

[0032] Wherein: A water inlet pipe 4 is arranged in the water inlet opened on the upper side of the front end of the box body 1. A water inlet valve is connected in series on the front side of the water inlet pipe 4. A drain pipe 5 is arranged in the drain outlet opened on the lower side of the front end of the box body 1. A drain valve is connected in series on the front side of the drain pipe 5. During operation, water enters the inside of the box body 1 through the water inlet pipe 4, and the flue gas enters the inside of the conveying pipe 72 through the air inlet pipe 73. During the process of the flue gas flowing inside the conveying pipe 72, the water will absorb the waste heat in the flue gas through the conveying pipe 72.

[0033] The working principle of a flue gas waste heat recovery and reuse device provided by the present utility model is as follows: Before use, the water inlet pipe 4, the drain pipe 5, the air inlet pipe 73, and the exhaust pipe 74 are respectively docked with external pipes. During operation, the water inlet valve, the air inlet valve, and the exhaust valve are opened. Water enters the interior of the box body 1 through the water inlet pipe 4, and flue gas enters the interior of the conveying pipe 72 through the air inlet pipe 73. During the process of the flue gas flowing inside the conveying pipe 72, water will absorb the waste heat in the flue gas through the conveying pipe 72.

When the contact point between the cam 13 and the adjusting plate 9 changes from the center to the far center, the cam 13 drives the sliding column 8 to move downward through the adjusting plate 9, the spring 11 contracts, the sliding column 8 drives the mounting ring 66 to move downward through the cross bar 10, and the mounting ring 66 drives the vertical rod 62 to move downward. When the contact point between the cam 13 and the adjusting plate 9 changes from the far center to the center, the thrust generated by the extension of the spring 11 drives the sliding column 8 to move upward and reset through the adjusting plate 9. During the upward movement of the sliding column 8, the sliding column 8 drives the mounting ring 66 to move upward and reset through the cross bar 10, and the mounting ring 66 drives the vertical rod 62 to move upward, so that the stirring fan blades 63 can drive the water to continuously churn through the lifting plate 64 while stirring the water, further increasing the contact area between the water and the flue gas. When the water absorbs too much waste heat and becomes hot water, the drain valve is opened, and the hot water is discharged through the drain pipe 5. After the hot water is emptied, the drain valve is closed again, and then new water is added into the interior of the box body 1 through the water inlet pipe 4, so as to continue to cool the flue gas.
