Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, and in particular to a novel vacuum heat conduction flue gas waste heat recovery device. Background Technology

[0002] Flue gas waste heat recovery refers to the use of technology to recover waste heat from industrial flue gas and convert it into usable energy (such as heat or electricity), thereby improving energy efficiency, reducing energy consumption, and reducing environmental pollution. The significance of flue gas waste heat recovery includes: Energy conservation and consumption reduction: recovering waste heat from flue gas reduces energy waste and lowers enterprise operating costs. Environmental protection and emission reduction: reducing heat loss in flue gas emissions and lowering greenhouse gas emissions. Improved energy utilization efficiency: converting waste heat into usable energy improves overall energy efficiency.

[0003] In existing novel vacuum heat conduction flue gas waste heat recovery devices, the flue gas contains a large amount of particulate matter and other impurities. These impurities easily accumulate inside the device, causing pipe blockage and affecting the heat conduction effect of the heat conduction plate. Therefore, we propose a novel vacuum heat conduction flue gas waste heat recovery device to solve the above-mentioned problems. Utility Model Content

Therefore, a novel vacuum heat-conducting flue gas waste heat recovery device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0030] As a preferred embodiment of this utility model, the fixing mechanism includes: a sliding plate 9, two push rods 11, two insert plates 12 and two fixing buckles 16;

[0031] The slide plate 9 is slidably connected to the front side of the filter plate 8. Two push rods 11 are symmetrically rotated and connected to the front side of the slide plate 9. Two insert plates 12 are symmetrically slidably connected to the front side of the filter plate 8. Two fixing buckles 16 are symmetrically fixed and connected to the front side of the filter box 3. The front side of the two insert plates 12 is rotatably connected to the rear side of the corresponding push rod 11. The two insert plates 12 are engaged with the corresponding fixing buckles 16. The movement of the slide plate 9 will push the two push rods 11. At this time, the movement of the two push rods 11 will push the two insert plates 12 to move closer to each other. At this time, the movement of the insert plates 12 will disengage from the fixing buckles 16, thereby unlocking the filter plate 8.

[0032] As a preferred embodiment of this utility model, a support plate 15 is fixedly connected to the front side of the filter plate 8, and the right sides of the two insert plates 12 are slidably connected to the left side of the support plate 15. The support plate 15 facilitates the limiting of the insert plates 12, so that the insert plates 12 can move stably and vertically.

[0033] As a preferred embodiment of this utility model, the front side of the support plate 15 is symmetrically and fixedly connected with guide plates 14, and there are two guide plates 14. The rear side of both guide plates 14 is fixedly connected to the front side of the slide plate 9. The guide plates 14 facilitate the limiting of the slide plate 9 and guide the slide plate 9 to move laterally in a stable manner.

[0034] As a preferred embodiment of this utility model, the front side of the filter plate 8 is symmetrically fixedly connected with a limiting plate 13, and there are two limiting plates 13. The limiting plate 13 has a hollow structure, and the outer wall of the insert plate 12 is slidably connected to the inner wall of the limiting plate 13. The limiting plate 13 facilitates the stable movement of the insert plate 12 and its engagement with the fixing buckle 16.

[0035] As a preferred embodiment of this utility model, two springs 10 are symmetrically fixedly connected to the left side of the support plate 15. The left side of each spring 10 is fixedly connected to the right side of the slide plate 9. The spring force of the springs 10 facilitates the lateral movement and reset of the slide plate 9.

[0036] It should be noted that the specific model of filter plate 8 to be used is to be selected by those skilled in the art, and the filter plate 8 and other related technologies mentioned above are all existing technologies, which will not be elaborated upon in this solution.

[0037] The working principle of this utility model is as follows: When waste heat recovery from flue gas is required, the inlet pipe 2, outlet pipe 4, water inlet pipe 5, and water outlet pipe 6 are connected to the corresponding pipes. Water is added into the outer casing 1 through the water inlet pipe 5. At the same time, hot flue gas is discharged into the outer casing 1 through the inlet pipe 2. Before entering the outer casing 1, the hot flue gas passes through the filter box 3. The filter plate 8 can filter impurities such as particulate matter in the flue gas. The hot flue gas heats the heat-conducting plate 7, thereby heating the water. The outer casing 1 has a hollow structure, and the inner wall of the outer casing 1 is provided with a heat insulation layer. The interior of the outer casing 1 is vacuum-filled. When the filter plate 8 is clogged and needs to be replaced, the sliding plate 9 is first pushed to move laterally. When the slide plate 9 moves, it compresses the spring 10. At the same time, the movement of the slide plate 9 pushes the two push rods 11. The movement of the two push rods 11 pushes the two insert plates 12 to move closer to each other. At this time, the movement of the insert plates 12 will disengage from the fixing buckle 16, thereby unlocking the filter plate 8. Then the filter plate 8 can be pulled out for replacement. When installing the filter plate 8, insert the filter plate 8 into the filter box 3. At this time, the slide plate 9 can be released. At the same time, the spring 10 loses its restraint and pushes the slide plate 9 to reset. The reset of the slide plate 9 will pull the push rod 11 to move, thereby driving the insert plate 12 to reset. The reset of the insert plate 12 will fix the filter plate 8 to the fixing buckle 16, thus achieving the effect of replacing the filter plate 8.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
