Description

Technical Field

[0001] The utility model relates to the technical field of industrial waste gas treatment, and more specifically, to a highly efficient industrial waste gas heat recovery device. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes within the enterprise's factory area. Since industrial waste gas will generate heat emissions during the emission process, the heat energy in the waste gas can be recovered through a heat recovery device and reused, thereby achieving energy conservation and emission reduction.

[0003] Based on the above, the inventors found that the existing heat recovery device uses the exchanger as the recovery body, and the exhaust gas and the water source perform heat exchange inside the exchanger, thereby playing a role in heat energy recovery, and filters are provided at the air inlet and the water inlet to reduce the entry of impurities into the exchanger. However, as the working time increases, impurities can easily cause the filter to be blocked, resulting in poor circulation of the exchange medium, affecting the effect of heat recovery. Therefore, in view of this, the existing structure is studied and improved to provide an efficient industrial waste gas heat recovery device, in order to achieve a more practical purpose.

[0029] The reciprocating mechanism 9 includes a driving motor 13, the output end of the driving motor 13 is fixedly connected to a rotating disk 14, an adjusting frame 15 is sleeved on the outer side of the rotating disk 14, and a group of first gear blocks 16 are fixedly connected to one side of the rotating disk 14, and a group of second gear blocks 17 are fixedly connected on both sides of the inside of the adjusting frame 15. In order to be able to quickly move and adjust the two filter screens 8 and facilitate the replacement of the filter screens 8, a reciprocating mechanism 9 is provided.

[0030] See also Figure 1The water inlet 2 and the air inlet 4 are arranged diagonally, and the water inlet 2 and the air inlet 4 have the same structure. The exhaust gas enters the exchanger 1 from the air inlet 4 and is discharged from the air outlet 5, while the water source enters the exchanger 1 from the water inlet 2 and is discharged from the water outlet 3. The waste water and the water source flow in the opposite direction and perform heat exchange inside the exchanger 1. Finally, the water source is heated up to complete the heat recovery work.

[0032] See also Figure 4 The impeller 11 faces the outside of the air inlet 4, and one side of the cleaning rod 12 is in contact with the outer surface of the filter 8. During the flow of exhaust gas, the impeller 11 is blown, and then the movable shaft 10 drives the cleaning rod 12 to rotate stably through the support frame 7, thereby cleaning the impurities adhered to the surface of the filter 8, reducing the blockage problem of the filter 8 and ensuring the smooth flow of the pipeline.

[0033] See also Figure 5 The driving motor 13 is fixedly connected to the outer surface of the exchanger 1, and the adjusting frame 15 is fixedly connected to the other end of the sliding plate 6.

The waste water and the water source flow in the opposite direction and perform heat exchange inside the exchanger 1. Finally, the water source is heated up to complete the heat recovery work. The exhaust gas entering the air inlet 4 is filtered for impurities through the filter 8. During the flow of the exhaust gas, the impeller 11 is blown, and then the movable shaft 10 drives the cleaning rod 12 to rotate stably through the support frame 7 to clean the impurities adhered to the surface of the filter 8, thereby reducing the clogging problem of the filter 8 and ensuring the smooth flow of the pipeline. When the filter 8 needs to be replaced, the drive motor 13 is started to drive the rotating disk 14 to rotate. When the rotating disk 14 moves from top to bottom, the first When a tooth block 16 is in meshing contact with a second tooth block 17 on one side of the adjustment frame 15, the adjustment frame 15 drives the sliding plate 6 to drop vertically, and the filter screen 8 located inside the air inlet 4 is moved out of the air inlet 4 to be replaced with a new filter screen 8. At the same time, the filter screen 8 located outside the air inlet 4 enters the air inlet 4 to continue filtering the exhaust gas. When the filter screen 8 needs to be replaced again later, the rotating disk 14 moves from bottom to top, and the adjustment frame 15 drives the sliding plate 6 to rise vertically, and the position adjustment of the two filters 8 is completed again. Similarly, the filter screen 8 inside the water inlet 2 can filter the circulating water source, and can cooperate with the corresponding reciprocating component to replace the filter screen 8, thereby reducing the problem of impurity accumulation and blockage in the recovery device.
