Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 to Figure 4In an embodiment of the utility model, an energy-saving industrial waste heat recovery device includes a recovery box 1 and a water tank 2 arranged on one side of the recovery box 1. The bottom end of one side of the recovery box 1 is connected to an air inlet 8 located below the support frame 3, which is used for the hot air generated by the industry to enter the recovery box 1. A plurality of faucets 9 connected to the inside of the water tank 2 are installed side by side on the side away from the recovery box 1, which are used for taking the heated water in the water tank 2. A display screen 10 located on the side wall of the water tank 2 is arranged above the faucet 9, which is used to display the temperature and water volume of the water in the water tank 2.

[0022] The interior of the recovery box 1 is provided with a heat recovery mechanism extending to one side of the water tank 2 and connected to the water tank 2. The heat recovery mechanism includes a first connecting pipe 41, a circulating pump 42, a water inlet pipe 43 and a water outlet pipe 44. A diverter box 45 is fixedly installed on the top and bottom of the inner wall of the recovery box 1. The two ends of the first connecting pipe 41 are connected and installed between the adjacent sides of the diverter box 45. The middle part of the side wall of the first connecting pipe 41 is installed on the inner wall of the recovery box 1 by bolts. A second connecting pipe 46 located between the diverter boxes 45 is provided on one side of the first connecting pipe 41. The two ends of the second connecting pipe 46 are connected to the diverter box 45. The ends are respectively fixedly installed on the middle part of the side of the diverter box 45, a circulating pump 42 is provided between the recovery box 1 and the water tank 2, and both ends of the circulating pump 42 are connected with water inlet pipes 43, the water inlet pipe 43 connected with one end of the circulating pump 42 extends to the inside of the bottom end of one side of the water tank 2, and the water inlet pipe 43 connected with the other end of the circulating pump 42 passes through the bottom of the recovery box 1 and is connected with one of the diverter boxes 45, and a water outlet pipe 44 connected with another diverter box 45 is fixedly installed on the top of the recovery box 1, and the end of the water outlet pipe 44 away from the recovery box 1 is connected and installed on the top of one side of the water tank 2.

[0023] There are nine first connecting pipes 41 evenly and equidistantly distributed between the sides of the diverter box 45. The first connecting pipes 41 are bent to maximize the contact area between the industrially generated hot air and the water source, thereby facilitating the improvement of the waste heat recovery rate.

[0024] When in use, after the industrially generated hot air enters the recovery tank 1, the circulation pump 42 is started to pump the water source in the water tank 2 through the water inlet pipe 43 to the diverter box 45 connected thereto, and then transported to the first connecting pipe 41 and the second connecting pipe 46 through the diverter box 45, so that the industrially generated hot air heats the water source in the first connecting pipe 41 and the second connecting pipe 46. The heated water source enters another diverter box 45, and then returns to the water tank 2 through the water outlet pipe 44, so that the water source in the water tank 2 is continuously heated in a reciprocating manner. The heated hot water in the water tank 2 can be used by the workers in the factory, avoiding the waste of industrial waste heat, thereby improving the utilization of industrial waste heat. At the same time, there is no need to heat the water source separately with the help of an external power supply, which saves energy. In this process, only the circulation pump 42 needs to be used to pump the water source back and forth, and less energy is used, which further improves the energy-saving effect.

[0025] A support frame 3 is welded to the side of the recovery box 1 away from the water tank 2. A purification mechanism for purifying the waste heat exhaust gas after recovery is provided on the top of the support frame 3. The purification mechanism includes a purification box 51, an air intake pipe 52 and a mounting frame 53. The purification box 51 is fixedly installed on the top of the support frame 3. The bottom ends of both sides of the purification box 51 are connected and installed with the air intake pipe 52. The ends of the air intake pipe 52 away from the purification box 51 are fixedly installed on the top of the recovery box 1. The interior of the purification box 51 is slidably plugged with the mounting frame 53. The mounting frame 53 is A handle 54 is welded on one side extending to the outside of the purification box 51. The purification mechanism also includes a filter mesh layer 55, an oil-absorbing sponge 56 and an activated carbon adsorption mesh layer 57 arranged inside the installation frame 53. A plurality of groups of placement blocks 11 are symmetrically welded on both sides of the inner wall of the installation frame 53. The two ends of the filter mesh layer 55, the oil-absorbing sponge 56 and the activated carbon adsorption mesh layer 57 are respectively slidably connected between the corresponding inner walls of the placement blocks 11, and the filter mesh layer 55, the oil-absorbing sponge 56 and the activated carbon adsorption mesh layer 57 are arranged from bottom to top in sequence.

[0026] When in use, the staff first opens the control valve of the exhaust port on the top of the purification box 51. At this time, the hot air generated by the industry enters the recovery box 1 and is utilized, and then enters the purification box 51 through the air inlet pipe 52. The gas passes through the filter mesh layer 55, the oil absorption sponge 56 and the activated carbon adsorption mesh layer 57 in turn and is filtered and purified by multiple layers. The clean gas after purification is discharged to the outside through the exhaust port on the top of the purification box 51, so that harmful substances in the industrial waste heat are removed, avoiding the impact of industrial waste gas on the atmosphere after being discharged to the outside.

[0027] A disassembly mechanism is provided at the end of the handle 54 for facilitating its installation and disassembly, and the disassembly mechanism includes a spring 61, a pull block 62 and a fixing rod 63. The sides of the purification box 51 are welded with fixing blocks 12 located above and below the handle 54 in parallel, and a spring 61 is welded on the side of the fixing block 12 away from the handle 54, and a pull block 62 is welded on the other end of the spring 61. A fixing rod 63 penetrating the spring 61 is welded on the side of the pull block 62 close to the fixing block 12. A fixing hole 64 matching the fixing rod 63 is provided at the top and bottom ends of the handle 54, and one end of the fixing rod 63 penetrates the fixing block 12 and extends to the inside of the fixing hole 64, and the fixing rod 63 is slidably connected to the fixing hole 64 and the fixing block 12.

[0028] During use, when the filter mesh layer 55, the oil absorbing sponge 56 and the activated carbon adsorption mesh layer 57 need to be replaced after being used for a period of time, first pull the pull block 62 to move it toward the side away from the handle 54. When the pull block 62 is pulled, the fixing rod 63 moves in the same direction accordingly, and the spring 61 is stretched and deformed accordingly. When the fixing rod 63 is continuously separated from the inside of the fixing hole 64, hold the handle 54 and pull it toward the side away from the purification box 51, so that the installation frame 53 is separated from the inside of the purification box 51, and then the filter mesh layer 55, the oil absorbing sponge 56 and the activated carbon adsorption mesh layer 57 are sequentially pulled out from between the inner walls of the placement block 11, and the filter mesh layer 55, the oil absorbing sponge 56 and the activated carbon adsorption mesh layer 57 can be replaced. The operation is simple and the work efficiency is improved.

[0029] Working principle: When using the energy-saving industrial waste heat recovery device, the hot air generated by the industry is first discharged into the recovery tank 1 through the air inlet 8, and at the same time, the circulating pump 42 is turned on to transport the cold water in the water tank 2 through the water inlet pipe 43 into the diverter box 45 connected thereto, and then transported to the first connecting pipe 41 and the second connecting pipe 46 through the diverter box 45. At this time, the hot air generated by the industry heats the water source in the first connecting pipe 41 and the second connecting pipe 46. The heated water source enters another diverter box 45, and then returns to the water tank 2 through the outlet pipe 44. In this way, the water source in the water tank 2 is continuously heated in a reciprocating cycle. When the hot air in the recovery tank 1 is used up, the staff opens the control valve of the exhaust port on the top of the purification box 51, and the gas enters the purification box through the air inlet pipe 52. The clean gas is discharged to the outside through the exhaust port at the top of the purification box 51. When it is necessary to dismantle and replace the filter mesh layer 55, the oil absorption sponge 56 and the activated carbon adsorption mesh layer 57 inside the installation frame 53, first pull the pull block 62 to drive the fixing rod 63 to move toward the side away from the handle 54, so that the fixing rod 63 is disengaged from the fixing hole 64, that is, the handle 54 is released from the restriction, and then the handle 54 is pulled to pull the installation frame 53 out of the purification box 51, and then the filter mesh layer 55, the oil absorption sponge 56 and the activated carbon adsorption mesh layer 57 are pulled out from between the inner walls of the placement block 11 in turn, and then they can be replaced.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
